Zipper pull head injection molding machine

Abstract

The invention discloses a zipper pull head injection molding machine. Disordered pull head main bodies are arranged through a vibration disc. Whether the pull head main body passes is automatically controlled through a discharging control device in butt joint with a discharging port so that only one pull head is ensured to pass each time and enters into one corresponding trough of a material arranging table. The pull head main bodies in the multiple troughs of the material arranging table are automatically grabbed and moved into a corresponding cavity of a lower die through a feeding device sothat injection molding operation of a hand pulling portion is performed on pulling boards of the pull head main bodies after die assembly, and then the pull heads are formed. Through an automatic part taking and water gap auxiliary shearing device, the pull heads after injection molding and a water gap connected with a hand pulling part are automatically taken out of the lower die and moved to awater gap shearing device. Under assistance of the automatic part taking and water gap auxiliary shearing device, the water gap is cut off through the water gap shearing device. A whole process is completed mechanically and automatically, manual operation is not needed, and production efficiency and product quality can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of mold production, in particular to a slider injection molding machine for zippers. Background technique [0002] Such as figure 1 As shown, it is a schematic structural diagram of a slider 10 of a zipper, which includes a main body 100 composed of a metal chain head 101 and a pull tag 102, and a plastic handle 103 covering the front of the pull tag 102. The plastic The handle portion 103 on the one hand can improve the comfort of the hand when pulling the slider 10, and on the other hand can make the slider 10 as a whole more beautiful and elegant. [0003] At present, the manufacturing method of this type of slider 10 is to manually put a plurality of prefabricated main bodies 100 (as for how the main bodies are made in the prior art, it will not be repeated here) into a plurality of corresponding cavities of a multi-cavity mold (i.e. The multi-cavity mold has multiple cavities) for injection molding to...

AI Technical Summary

Problems solved by technology

However, by manually feeding materials, taking parts and manually cutting them one by one, or manually taking parts and placing them in an automatic shearing device for one-time cutting, there are problems of low efficiency and excessive burrs after cutting, which will affect the quality of the slider 10. question
