Description

Plastic mould production is with flexible koch of secondary Technical Field The utility model relates to the field of mold production, in particular to a secondary telescopic lithocarpy for plastic mold production. Background The plastic mould is a tool matched with a plastic forming machine in the plastic processing industry and endows a plastic product with complete configuration and accurate size. Because of the variety of plastics and the variety of processing methods, the structures of the plastic molding machine and the plastic products are various, and the variety and the structure of the plastic mold are also various. However, the existing plastic mold has the following problems in production: When the existing mold cavity of the mold is used for producing plastic products, after plastic is heated and softened in the mold, the products can be tightly adsorbed on the surface of the mold in the cooling process due to the cooling effect of the mold, so that the plastic products are difficult to demold, and can be caused by the reasons that the temperature of the mold is too high or too low, the design of a cavity is unreasonable and the like, so that great inconvenience is brought to the production, and the secondary telescopic joint for producing the plastic molds is necessary to be used in the existing mold production field. Disclosure of utility model In order to make up the deficiency of the prior art, when the die cavity of the existing die produces the plastic product, after the plastic is heated and softened in the die, the product can be tightly adsorbed on the surface of the die in the cooling process due to the cooling effect of the die, so that the plastic product is difficult to demold, and the problem that the production is inconvenient is caused by the reasons that the die temperature is too high or too low, the design of the die cavity is unreasonable and the like. The technical scheme adopted by the utility model for solving the technical problems is that the secondary telescopic lithocarpy for producing the plastic mould comprises the following steps: The device comprises a pressing plate, wherein a mounting opening is formed in the middle of the pressing plate, a plurality of first sliding blocks are fixedly arranged on the inner wall of the mounting opening, one ends of the first sliding blocks extend out of the pressing plate, a plurality of traction grooves are formed in the inner wall of the mounting opening, the traction grooves are located between the two first sliding blocks, and traction sliding grooves are formed in the inner walls of the first sliding blocks; The secondary telescopic lithocarpy mechanism comprises a second sliding block, and a plurality of second sliding blocks are movably assembled with the mounting opening. The one end of second slider is all fixed mounting has the connecting rod, and the one end fixed mounting of a plurality of connecting rods has the go-between. And traction sliding blocks are fixedly assembled on the lower parts of the surfaces of the second sliding blocks, and the traction sliding blocks are correspondingly and movably assembled with the traction grooves. And the second sliding blocks are fixedly provided with operation sliding blocks, and the operation sliding blocks are positioned on the inner sides of the second sliding blocks. The inner side of the second sliding block is provided with a central core, and the central core is positioned on the inner side of the connecting ring. The three side surfaces of the central core are fixedly provided with guide sliding blocks, and the guide sliding blocks are correspondingly and movably assembled with the traction sliding grooves of the first sliding blocks. The three end faces of the central core are respectively provided with a guide chute, and the guide chutes are correspondingly and movably assembled with the operation slide blocks of the second slide blocks. The bottom of the traction sliding block is provided with traction holes, and the bottom of the central core is provided with a guide hole. The utility model has the advantages that: The device performs secondary shrinkage, optimizes the primary shrinkage, ensures that the product can shrink again under the condition of the same height and back-off, ensures that the buckling stroke of the product Ke Chuchan is larger, further increases the producibility of the product, ensures that the secondary shrinkage and the shrinkage mechanism is in a shrinkage state, provides enough filling space for injection molding materials, and ensures that the secondary shrinkage and the shrinkage mechanism stretches out to assist the smooth demoulding of the product when the mould is opened, and ensures the accuracy and the reliability ‌ of the action by a mechanical structure or a hydraulic system in the mould.
