Description

Technical Field

[0001] The utility model relates to the technical field of plastic product processing, in particular to an automatic shear bracket fixture. Background Art

[0002] In our daily lives, more and more plastic products are being used, and these are generally produced using injection molding. Injection molding is a method for producing industrial products, typically using rubber and plastic injection molding. Injection molding can also be divided into injection molding and die casting. Plastic injection molding involves melting plastic pellets and injecting them through an injection mold.

[0003] As is known, during the injection molding process, liquid raw material is injected into the mold cavity through the injection port. After the raw material cools, a workpiece is formed and sprue waste is formed at the injection port. To improve injection molding efficiency, at least two or more workpieces can be molded at a time. Because the raw material is connected within the injection cavity during the injection molding process, the waste generated by cooling the molding process will usually connect multiple workpieces. This is inconvenient for the transportation and storage of the workpieces. Therefore, in the prior art, the waste is usually cut off by the operator, which greatly reduces the efficiency of the injection molding workpiece and has certain shortcomings. Utility Model Content
