A kind of zipper injection molding machine and zipper injection molding method

Abstract

The present invention relates to the technical field of zipper production equipment, specifically to a zipper injection molding machine and a zipper injection molding method. The zipper injection molding machine comprises a working table, an injection molding host machine, a conveying device and a belt loosening device, wherein the injection molding host machine comprises a lower mold arranged on the working table, an upper mold arranged above the lower mold, and a host machine drive mechanism for driving the upper mold to move toward the lower mold direction, the conveying device is used for tensioning or driving a chain belt to pass through between the upper mold and the lower mold of the injection molding host machine, and the belt loosening device is arranged on the working table and is used for loosening the chain belt tensioned on the conveying device before the chain belt on the conveying device is subjected to injection molding by using the injection molding host machine. According to the present invention, the zipper injection molding machine has characteristics of high synergy degree, rapid production speed and low error; and the chain belt is loosened by the belt loosening device before the injection molding host machine performs injection molding on the chain belt so as to make the chain belt be subjected to injection molding during being loosening, such that the chain belt deformation range is small, the flat chain belt is ensured, and the product quality is good.

Description

technical field [0001] The invention relates to the technical field of zipper production equipment, in particular to a zipper injection molding machine and a zipper injection molding method. Background technique [0002] As a big zipper production country, my country accounts for 50%-60% of the world's total production. As the zipper industry develops in the direction of low cost, high quality, large scale and intensification, the requirements for zipper production efficiency and automation equipment are also increasing. higher. [0003] Existing, injection molding machine is used for the zipper teeth of plastic-steel zipper or upper and lower stops on chain belt on chain belt injection molding, and existing injection molding machine (as authorization announcement number is: CN202053457U disclosed full-automatic four-color zipper Mi injection molding machine) usually includes a workbench, an injection molding host and a belt puller. When the injection molding host is injecte...

Problems solved by technology

[0003] Existing, injection molding machine is used for the zipper teeth of plastic-steel zipper or upper and lower stops on chain belt on chain belt injection molding, and existing injection molding machine (as authorization announcement number is: CN202053457U disclosed full-automatic four-color zipper Mi injection molding machine) usually includes a workbench, an injection molding host and a belt puller. When the injection molding host is injected, the belt puller stops conveying the chain belt. At this time, the chain belt is tensioned by the belt puller. The defects of the existing injection molding machine mainly include the following Two points: one is that the injection molding machine and the belt puller are controlled separately, and deviations occur in the control process, resulting in errors; the other is that the high temperature generated by the injection molding machine during the injection molding process will easily deform the chain belt, resulting in uneven chain belts after injection molding. quality cannot be guaranteed
