First, prepare a steel scale (5 kg scale), seasoning bucket (or plastic basin), bibimbap (or bamboo chopsticks) and small spoon (plastic, aluminum or porcelain spoon); Secondly, according to the size of the mold and the number of products made, the unsaturated resin is weighed, poured into the seasoning barrel, and then the curing agent is added according to the ratio of (): (accelerator). First, add curing agent to unsaturated resin and fully stir (), then add accelerator and stir, and dilute after fully mixing (the same stirring), and then add materials according to the required color (). In order to reach the required level, a large amount of pigments can usually be used. ) when adding pigment, dissolve the pigment with resin, stir it internally, pour it into a bucket and stir it fully. After stirring, add the bottom material, and add it while stirring until it reaches the required level. (The prepared mixed slurry should be viscous, so that it can flow slowly after being scooped up with a spoon. Thirdly, the inverted mold should be square and flat, and the surface of the inner mold of the mold should be clean (horizontal) for pouring. When pouring, pour the slurry with a small spoon, not pour it. Pour from the highest point to make it flow naturally, so that bubbles can be squeezed out, otherwise there will be pores after the finished product. When pouring into the mold, be careful not to overflow the periphery of the mold. After pouring out the periphery, it should be cleaned and removed immediately, otherwise it needs to be treated and polished after molding. Pour the slurry into the mold for 1-2 hours, then it can be solidified, and then it can be demoulded. A manufacturing method of unsaturated resin artworks is characterized by comprising the following steps: (1) manufacturing a mold with silicone rubber according to the shape of the resin artworks; (2) adding a proper amount of filler into the unsaturated resin and uniformly stirring; (3) Before pouring into the mold, adding curing agent and accelerator into the unsaturated resin, and pouring into the mold after stirring evenly; And (4) demoulding after curing the resin to obtain the artwork with the required shape. It can pour various shapes of simulated handicrafts at room temperature, and has the advantages of rapid solidification, realistic details and simple process. 2

The manufacturing process of unsaturated resin handicraft mold is 1, and the mold opening methods include slicing, packaging, demoulding, painting and pouring. 2. Mold opening procedures mainly include mold repairing, plate arranging, soil piling, mold brushing, mold pouring, plastering and mold reversing. 3. The main materials for mold opening are silicone rubber, silicone oil, hard oil, hardening aid, gypsum, gauze and fiber. Second, the method of sorting out the mold seeds and faults, pouring out the mold seeds, polishing the bottom with the first generation, trimming the embryo, repairing and polishing, and determining whether the mold seeds are accessories, whether the mold seeds can be filled with oil soil and whether the mold seeds can achieve the effect of the template. 1, and the number of mold species decreased by 0. 1 mm per regeneration generation. It is best to use the first generation as a mold species. 2, the mold does not remove oil, which will affect the surface finish and production quality. 3. The mold sometimes needs accessories, and the clamping position of the accessories should be appropriate, and the position of the interface should be appropriate. 4. The mold should not have bad problems such as wire drawing, burning, graininess, porosity and deformation. 5. There is a great difference between the mold and the template, which may be caused by the shrinkage of the mold. 6. If you can't leave the mold at the depth of the mold, can you fill it with oil soil? 7. Parts with smooth mold requirements should be polished with sandpaper, and low molding sand should be used according to mold requirements. 8. The effect of the mold cannot be different from that of the template. 9. Whether the mold is easy to make mistakes and whether the mold line protection layer is attached according to the mold requirements. Third, the method and failure of plate arrangement determine the size and 90-degree angle of the bottom plate according to the size of the mold, and then determine the size of the grouting groove. The other inlet should be suitable, provided that the slurry can reach all parts. The distance between dies is a reference for arranging plates from the structure and mode of dies and the production requirements of the process. 1, inappropriate grouting groove and blanking position affect white embryo grouting production. 2. Determine the 90-degree angle of the bottom plate. If the bottom plate is not straight, it will affect the soil piling operation. 3. If the slurry at the lower discharge port cannot completely reach all parts, the discharge point should be increased. 4. Glue waste caused by excessive mold spacing. 5. Know the size, structure and opening mode of the die before arranging the plates. Four. According to the type of mold and production requirements, firstly, determine the mold opening mode and the position of the mold line, stack the oil soil along the mold line, cut the oil soil into rectangles or squares, then determine the nailing mode of the oil soil board, and finally trim the edge, which should be clean and smooth. Wash oil stains with soapy water. 1, the wrong position of the mold line causes inconvenience to the white blank production line for grouting and white blank, and also brings inconvenience to sanding. 2. The size of oil stain depends on the size of gypsum coating. 3. Unclean trimming leads to the multilateral phenomenon of the die. 4. Improper nailing between the inner mold and the outer mold will lead to grouting and slurry exposure. 5. The thickness of clay is equal to the thickness of internal model. 6. Sometimes, the internal mold with soil coating has to be operated, and it cannot be demoulded without operation. 7. The quality of trimming and the mold line are interrelated. 5. The method and fault of brush casting mold are whether to add silicone oil, paste gauze and add top position according to the different mold types and production needs. Then determine the economical proportion of hardening, and take time to brush the mold after seasoning with silica gel. The thickness and thickness of the brush mold are the same, and the dead angle should be brushed in place to avoid the difference in thickness. According to the different types and production requirements of the mold, the mold is surrounded by a fence, the tin-coated seasoning is poured into the fence for hardening, the fence is removed after hardening, and then plastering is carried out. 1, the amount of curing agent is determined according to the weather temperature, and the shrinkage of the mold decreases if the curing agent is too large. 2. Inappropriate brush at the horn of the brush die causes die, die burning, die and die aging. 3. The thickness of the brush die is different, which makes the die easy to break. 4. According to whether the mold between the jacket and the internal mold is disassembled, decide whether to add a jacking position. 5. Over-sealing of the casting mold leads to the waste of silicone rubber, and the size of the mold (casting mold) is determined by the sealing size. 6. Due to factors such as brushing technology and materials, there are bubbles in the mold. 7. Insufficient time of vacuum sealant will produce bubbles in the mold and affect the quality of white embryo. The manufacturing method and shortcomings of intransitive verb overcoat 1. The gypsum coating is surrounded by wooden boards and determines the concentration and weight of gypsum to be poured into the shell. To be determined, remove the shell, trim the gypsum coating and fix the position of the coating. Before plastering, the plastering method should be determined according to different mold types and production requirements. 1, the gypsum coating is too heavy, which makes it inconvenient to make white embryos, and the gypsum coating is too thin and easy to break. 2. The gypsum is too thick, causing bubbles in the coat. 3. The plastering method is wrong, which brings inconvenience to grouting operation. 4. Gypsum coat can't be fused, and white embryo grouting will cause slurry leakage or wrong mould. 5. Whether there is multilateral phenomenon in the dressing of gypsum coating.

Secondly, the fiber jacket has the advantage of reducing the weight of the mold and bringing convenience to the work. According to different mold types and production requirements, determine the fixing type, then determine the coating thickness, the ratio of Polly slurry to gypsum and the number of fiber layers, brush Polly slurry on the mold, paste the fiber, and brush Polly slurry on the mold again with the same thickness. Repair the coat after setting. Fiber coating is mainly used for large products. Her disadvantage is that it is easy to deform when used for too long. 1, the fiber sheath is not firm, resulting in white embryo grouting and pulp exposure. 2. Whether the ratio of Polly pulp to fiber is appropriate. 3. Inconsistent clamping position of fiber jacket leads to exposure of white embryo, wrong mold, and even affects product deformation. 4, the fiber jacket is deformed, and the products produced by white embryo will also be deformed.

3. After the jacket of the mold is turned back and forth, only half of the mold is actually made except for the outer plate and oil stain, and then the mold opening process is carried out again. After the whole mold is completed, half of it will be dismantled for production, and the number of turns will be determined according to the quality requirements, and one set of mold will be formed at a time. Too many inversions of 1. will lead to polygonal mold, large mold line and deformation of the mold. 2. The position of the operation is wrong, which leads to the inconvenience of white embryo production.

Fourthly, the operation method of mold is mainly used for pouring mold, and other molds sometimes operate. The position and degree of operation are determined according to the size and structure of the mold and the production requirements, and the mold can be pulled out.

Verb (abbreviation of verb) Repairing the finished mold After the finished mold is completed, there are bubbles and multiple layers in the mold due to factors such as technology and materials. First, make bubbles, and then use scissors to remove multiple layers. If these two problems are not solved, it will directly affect the white embryo grouting operation and quality.
