Automatic penetrator injection molding machine for plastic steel closed-end zippers

Abstract

The invention discloses an automatic penetrator injection molding machine for plastic steel closed-end zippers. The automatic penetrator injection molding machine comprises a workbench, a puller supply device, a penetrator device and an injection molding positioning assembly, wherein the workbench is provided with a zipper conveying device, the puller supply device, the penetrator device and the injection molding positioning assembly are arranged on the workbench, a zipper conveying path sequentially passes through the penetrator device and the injection molding positioning assembly, and the puller supply device provides pullers for the penetrator device; the puller supply device comprises a puller vibrating plate for accommodating pullers and a puller guide rail for outputting the pullers; and the penetrator device comprises a puller clamping assembly and a puller inlet guide plate, the puller clamping assembly is used for clamping pullers from the puller guide rail, the puller inlet guide plate can move to a zipper conveying track, the zipper conveying device can draw zippers to pass through the puller inlet guide plate, and the puller clamping assembly can clamp pullers from the puller guide rail, and enable the pullers to move to the puller inlet guide plate relative to the zipper vacancies of zippers and then penetrate the zipper vacancies.

Description

technical field [0001] The invention relates to the technical field of zipper production equipment, in particular to a plastic-steel closed-end zipper automatic head-threading injection molding machine, which is applied to the process of head-threading and injection molding of the upper and lower stops of the closed-end zipper. Background technique [0002] Closed-end zipper is a kind of zipper with closed tail, and the two zipper pieces cannot be pulled out from the zipper puller. It is commonly used in trousers, bags and other equipment where the zipper puller does not need to completely separate the two zipper tapes. Most of the current Wuwei zipper production equipment adopts the method of threading the head first, and then performing upper and lower stop injection molding, and is produced by different equipment. The main problems of this method are that the production process is long, the occupied area is large, the production capacity does not match, resulting in on-si...

Problems solved by technology

[0003] The purpose of the present invention is to provide a plastic-steel closed-end zipper automatic head-piercing injection molding machine. The main technical problem to be solved is: the traditional closed-end zipper is produced by different equipment to wear the head and stop the plastic, and the production process is long. It is labor-intensive and energy-intensive, and the position change of the zipper is likely to cause the zipper to become knotted, resulting in downtime and low production efficiency.
