Description

Technical Field

[0001] The utility model relates to the technical field of mold structures, in particular to a quick-detachable material removal device in a mold. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. It is known as the "mother of industry". The mold generally consists of two parts: the upper mold and the lower mold. The two parts can be separated or combined. When separated, the workpiece is taken out, and when closed, the blank is injected into the mold cavity for forming. At present, during the stripping process of the mold, tools are needed to remove the mold after molding. On the one hand, when a large force is applied during the removal process, the mold after molding will be deformed, resulting in the mold becoming a defective product. On the other hand, if the molding mold is removed too slowly, it will affect the overall mold manufacturing efficiency, seriously affecting the mass production of the mold, and at the same time reducing the use effect of the quick-detachable stripping device in the mold, and also affecting the stripping efficiency of the quick-detachable stripping device in the mold.
