Production mould for plastic zippers

Abstract

The invention discloses a production mould for plastic zippers. The production mould includes a machine base. A support column is vertically disposed in the middle of the upper surface of the machine base. A rotary bearing sleeves the top end of the support column. A revolving bench is fixed on the upper surface of the rotary bearing. A plurality of lower dies are clamed uniformly onto the outer edge of the upper surface of the revolving bench by means of bolts. An upper die is buckled with the upper surface of each lower die, wherein a cavity is formed between each lower die and each upper die and is corresponding to a zipper head. In the mould, a plurality of the lower dies and upper dies rotate along with the revolving bench. During the rotation, plastic poured into the cavities is cooled to form the zipper head. A product in the cavity is removed by means of a punching air cylinder through a punching column and then falls into a material hopper. According to the cooling speed of the plastic, a servo motor and the punching air cylinder are cooperated so as to continuously and automatically produce the plastic zipper heads. The production mould improves automatic degree and production efficiency and further reduces comprehensive cost.

Description

technical field [0001] The invention relates to the technical field of zipper moulds, in particular to a plastic zipper production mould. Background technique [0002] The zipper is a connecting piece that relies on the continuous arrangement of elements to merge or separate items, and is now widely used in clothing, bags, tents, etc. A fastener consisting of a row of metal teeth or plastic teeth on each of the two straps is used to connect the edges of the opening (such as the mouth of a garment or a bag), and a slider can pull the two rows of teeth into an interlocking position to close the opening and connect A chain attached to something (as an object to be lifted or dropped) to tighten, stabilize or guide it. The zipper head in the prior art is formed by a zipper head mold, but the zipper production mold generally adopts a single molding, which needs to wait for cooling, and then manually pour the mold for mass production, which is very inconvenient to process, has low...

AI Technical Summary

Problems solved by technology

The zipper puller in the prior art is formed by the zipper puller mould, but the zipper production mold generally adopts a single molding, which needs to wait for cooling, and then manually reverse the mold for mass production, which is very inconvenient to process, low in production efficiency, and cannot realize continuous production. Processing, the comprehensive cost is higher in the processing process
