Zipper slider mounting mould self-adaptive to different zipper pulls hanging ring sizes

Abstract

A zipper slider mounting mould self-adaptive to different zipper pulls hanging ring sizes comprises a mould base and a top plate arranged at the top of the mould base, a mounting groove is arranged on each of two side arms of the mould base which is provided with a zipper pulls hooking block in a matching manner, and guide projections are arranged on two sides of the zipper pulls hooking block respectively and are assembled to the two mounting grooves respectively. Each guide projection is provided with a through hole, a limit rod capable of freely sliding up and down is assembled in each through hole, an ejector pin in horizontal projection is arranged at the top of each limit rod, and a first pressure spring and a second pressure spring are further sleeved on the outer side of each limit rod and are arranged above and below the corresponding guide projection respectively. The zipper slider mounting mould self-adaptive to the different zipper pulls hanging ring sizes in the application has the advantages that zipper sliders cannot be pull out, and quality of products can be well guaranteed; a worker does not need to adjust the height of a stopper according to pull rings of different sizes, and production efficiency is improved; and replacement times of the mould are decreased effectively, and service life of the mould is prolonged.

Description

technical field [0001] The invention relates to a zipper head piercing die, in particular to a zipper head piercing die which is self-adaptive to the sizes of different pull tab hanging loops. Background technique [0002] Such as figure 2 As shown, the existing zipper head piercing die is made up of a stopper, a hook pull piece, a stage clip, a limit block, and a base mold base. The main working principle is: when the slider is placed at a fixed position, the hanging ring on the slider will drop and hook on the hook on the hook piece; the entire mold base moves upward under the action of the cylinder, and the block will touch at this time. Hook the pull piece, press the hook pull piece to stop it from rising, the hook pull piece will pull down the pull piece hanging ring, lift the horse hook, so that the cloth belt can pass through the slider without getting stuck live. However, because the size of the hanging ring of different pull pieces is different, when changing the...
