How to make resin crafts?
First, prepare a steelyard (5 kg scale), a seasoning bucket (or plastic basin), covered rice (or bamboo chopsticks) and a small spoon (plastic, aluminum or porcelain spoon); Second, according to the size of the mold and the number of products produced, the unsaturated resin is first weighed, (combined) 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, fully stir (), then add accelerator, fully mix, dilute (stir the same), 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 the pigment, dissolve the pigment with resin, stir it inside, and pour it into a bucket for full stirring. Add the bottom material after stirring, and add it while stirring until the required liquid level is reached. (The prepared mixed slurry should be sticky, so that it can flow slowly after being scooped up with a spoon and poured down. Third, the inverted mold should be square and level, and the inner surface of the mold should be cleaned (horizontal) for pouring. When pouring, pour the slurry with a small spoon, not pour it. Pour from the highest point and let it flow naturally, so that bubbles can be squeezed out, otherwise there will be pores after the finished product. Be careful not to overflow the periphery of the mold when pouring it into the mold. After pouring out the periphery, it should be cleaned and removed immediately, otherwise it needs to be processed and polished after molding. The slurry can be solidified after being poured into the mold for 1-2 hours, 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 be used to pour various shapes of simulated handicrafts at room temperature, and its three-dimensional modeling is rapid, the details are realistic and the process is simple. 2
The manufacturing process of unsaturated resin handicraft mold is 1, and there are a series of mold opening methods such as 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 mold species and the fault of dumping mold species. The first generation is used to grind the bottom, repair the embryo and sand, and determine 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, the card 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, granularity, 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. Can the mold be filled with oil soil if there is no mold left in the depth of the mold? 7. The smooth part of the mold should be sanded, and low molding sand should be used according to the 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 on the premise 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, the grouting groove and blanking position are not suitable, which affects the 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. Before arranging the plates, first understand the size, structure and opening mode of the die before arranging the plates. Four. According to the types of molds and production requirements, first determine the mold opening mode and the position of the mold line, pile the oil soil along the mold line, cut the oil soil into rectangles or squares, then determine the nailing mode of the oil soil plate, and finally trim the edges with neat and smooth edges. Wash oil stains with soapy water. 1, the wrong position of the mold line will cause inconvenience to grouting and blank production line, and will also bring inconvenience to sanding. 2. The size of oil pollution depends on the size of gypsum layer. 3. Unclean trimming caused the multilateral phenomenon of the mold. 4. Improper nailing between the inner mold and the outer mold will cause 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 the mold can't be released without operation. 7. The quality of trimming and the mold line are interrelated. 5. The method and fault of brush casting mold are based on the different mold types and production needs, whether to add silicone oil, paste gauze and add top position. Then determine the economic proportion of hardening, season with silica gel for a period of time, and then brush the mold. The thickness of the brush mold is consistent, and the dead angle should be brushed in place to avoid the thickness difference. 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 depends on the weather temperature, and the shrinkage of the mold decreases if the curing agent is too large. 2. Inappropriate brush at the corner of the brush die causes die, burning die, die and die aging. 3, the thickness of the brush die is different, which leads to the die being easily broken. 4. Decide whether to add jacking position according to whether to disassemble the mold between the jacket and the internal mold. 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 size of the sealing. 6. Due to factors such as brushing process and materials, there are bubbles in the mold. 7. Insufficient vacuum sealing time will cause bubbles in the mold, which will affect the quality of white embryo. The making method and shortcomings of intransitive verb coat 1. The gypsum coat is surrounded by wooden boards, and the concentration and weight of gypsum are determined and poured into the fence. After confirmation, 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 makes the grouting operation inconvenient. 4. Gypsum coats cannot be combined, and white embryo grouting will cause slurry leakage or wrong formwork. 5. Whether there is multilateral phenomenon in the wearing of plaster coat.
Second, the advantage of fiber coating is to reduce the weight of the mold and bring convenience to the work. According to the different mold types and production requirements, determine the fixed 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 then brush Polly slurry on the mold 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 sheath leads to white embryo exposure, wrong mold and even affects product deformation. 4, fiber sheath deformation, white embryo products will also be deformed.
3. After the jacket of the mold is turned back and forth, except for the outer plate and sludge, only half of the mold is actually made, and the mold opening process is carried out again. After the whole mold is completed, half of it will be dismantled for production, and the turnover times will be determined according to the quality requirements, and one set of mold will be formed at a time. Too many inversions of 1. lead to polygonal mold, large mold line and deformation of the mold. 2. The wrong posture of operation leads to inconvenience in making white embryos.
Fourth, the operation method of the mold is mainly used for pouring molds, and other molds are sometimes operated. 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, bubbles and layers appear in the mold due to factors such as technology and materials. Fill up the bubbles first, and then remove the layers with scissors. If these two problems are not solved, it will directly affect the operation and quality of white embryo grouting.
