A plastic wrap metal sheet mold

Abstract

A preservative film metal sheet die comprises an upper die assembly and a lower die assembly. The upper die assembly comprises an upper die base, a backing plate and a male die fixing plate; the lower die assembly comprises a lower die base, a female die fixing plate and an unloading plate; a material strip is arranged between the upper die assembly and the lower die assembly; a male die assembly for stamping is fixed to the male die fixing plate, and a female die assembly is fixed to the position, corresponding to the male die assembly for stamping, of the female die fixing plate, wherein female dies are equal to male dies in number and complementary to the male dies in shape; the male die assembly comprises several male dies used for carrying out cutting towards the lower left, several male dies used for carrying out cutting towards the lower right and one male die used for cutting off edge materials, and the female die assembly comprises several female dies used for carrying out cutting towards the lower left, several female dies used for carrying out cutting towards the lower right and one female die used for cutting off edge materials. According to the preservative film metal sheet die, in the process of production, the opposite-angle cutting technology is adopted for the male dies and the female dies, and therefore sharp corners of sawteeth of the product can be guaranteed.

Description

technical field [0001] The invention relates to a mold, in particular to a plastic wrap metal sheet mold. Background technique [0002] In daily life, plastic wrap is widely used. When using plastic wrap, the metal sheet on the plastic box is usually used to tear off the plastic wrap. The mold manufacturing technology has the advantages of fast forming, batch processing, and guaranteed processing accuracy. Advantages, most of the production of plastic wrap metal sheets currently uses the method of die cutting, but because the serrations of the metal sheets produced by continuous single-line cutting in the existing method are not sharp enough, it is difficult to form them in one mold, which is not only time-consuming and laborious, but also increases labor costs and production efficiency. At the same time, it will cause waste of material use and inaccurate precision. Contents of the invention [0003] The technical problem to be solved by the present invention is to provid...
