Abstract

The invention discloses a zipper stamping upper die. The zipper stamping upper die comprises a cutter and die halves, wherein the die halves are mounted at the left side and the right side of the cutter. The cutter is used for cutting off a tooth head of each zipper tooth. Each die half is internally provided with a blowing channel, wherein each blowing channel is used for guiding in high-pressuregas. By means of the cutter, the tooth head of each zipper tooth is cut off. The blowing channel in each die half guides in the high-pressure gas which is used for blowing away broken teeth generatedin the cutting-off process. The zipper stamping upper die has the beneficial effects that by means of the zipper stamping upper die, the problems that the broken teeth generated in the zipper stamping process are not stamped thoroughly, and the broken teeth are clamped in tooth clamping grooves and cannot fall off can be solved.

Description

technical field [0001] The invention belongs to the technical field of slide fasteners, and in particular relates to an upper mold for punching chains. Background technique [0002] On the zipper product punching and sizing mold currently used, the air port for blowing teeth on the clamping slider is placed on the side of the slider, causing two problems: [0003] 1. During assembly, the air on the sliders on both sides blows against each other, causing broken teeth to fly randomly, and even fly into the zipper product, so that the broken teeth will be pressed on the surface of the zipper product during the next flushing, causing product damage; [0004] 2. Because the air port is on the side, the broken teeth cannot be completely blown out, and the broken teeth are caught in the tooth socket and cannot be blown out, which will affect the next flushing, resulting in unclean tooth flushing and defective products. Contents of the invention [0005] The purpose of the presen...
