Abstract

The invention discloses a metal zipper double-edge tooth selection mould. The mould comprises an upper mould base, a lower mould base and a tooth punching device located between the upper mould base and the lower mould base; the metal zipper double-edge tooth selection mould further comprises a strip pressing device, a tooth pressing device, a tooth pushing device and tooth selection devices which are arranged to be at the left side and the right side and symmetrical; each tooth selection device comprises a tooth selector used for positioning teeth of a selected distance of zipper teeth located at one side, and each tooth selector is provided with a clamping groove matched with the corresponding teeth; the strip pressing device is used for pressing a cloth strip at one side of a zipper, the tooth pressing device is used for pressing teeth at the side and driving the teeth to slide to the clamping groove in the corresponding tooth selector at the side, the tooth pushing device is used for pushing zipper teeth at the other side so that teeth of the selected distance can slide in the clamping groove in the corresponding tooth selector at the same. The zipper teeth of the zipper punched through the mould are stable in length, the mould can be adapted to zipper teeth which belong to the same type of zippers and are different in tooth distance, and thus the effect that tooth trimming is not needed at the two edges can be achieved.

Description

technical field

[0001] The invention relates to a metal zipper bilateral tooth selection mold. Background technique

[0002] During the processing of the metal zipper, teeth are selected according to the length of the required zipper, and then part of the teeth are removed by the tooth punching device to form several zipper sections of equal length, and then the upper stop and the lower stop are installed. The existing gear punching die includes upper and lower mold bases, gear punching cutter and gear selection mechanism. The zipper blank is located above the mold and can move from one side to the other. After the length is selected by the gear selection mechanism, the zipper stops and the gear punching knife falls. Flush the teeth off the zipper blank. Because the cloth tape of the zipper blank has a certain degree of elasticity, the zipper has a certain inertia and will still slide forward for a small distance when it stops, so that the number of teeth on the selected zi...
