Embodiment Construction

[0019] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments of the present invention will be described in detail below with accompanying drawings.

[0020] As shown in Figures 1 to 3, the improvement of the hook-tooth positioning structure of the zipper in the preferred embodiment of the present invention is mainly to sew two continuous zipper cloth strips 90 with several zipper teeth 91, and the zipper cloth strips The zipper teeth 91 of 90 protrude from the corresponding inner side of the zipper cloth strip 90, and the two zipper teeth 91 form a missing tooth portion 92 with each other, and the two zipper cloth strips 90 are separated by a pulling assembly [ not shown] lead and pull, so that the two zipper cloth strips 90 are guided through the positioning structure of the present invention to form precise movement and positioning, and then the two zipper cloth strips 90 are introduced into a...

Abstract

The drag chain hook type positioning structure improvement comprises the base, a trigger component, two hook and pulling structure, a positioning sensing part and a pressed part. The base comprises the top base plate, a bottom plate, a guide slot between the top and bottom base plates to guide a pull chain cloth strip. The triggering component is used to control the action of the hook structure. The two hook structure set an action plate set that can move downward and restrict the displacement of the drag chain cloth strip, to control the stopping of the mold to a position precisely. The positioning sensing part sets on the bottom plate of the base to ensure the action plate set restored to original position to start the action for the cloth strip fitting parts. The pressed part can press the drag cloth strip tightly between the pressed part and the top base. It can improve the yield rate.

Description

technical field [0001] The present invention relates to the improvement of a hook-tooth positioning structure for zipper shooting, and particularly relates to a method of using signals sent by two switches to control the action of a hook-pull mechanism, so that a zipper strip can be accurately stopped at a suitable position of a forming mold. Relative position, so that several accessories are shot onto the positioning structure of the zipper cloth strip. Background technique [0002] The commonly used injection positioning structure for zippers is as described in the Taiwan Patent Announcement No. 208889 "Feeding Injection Structure for Zipper Opening" that was previously applied by the applicant. A feeding positioning mechanism is arranged in front of a combination mold. The feeding positioning mechanism is provided with an upper seat plate, a lower seat plate and a gear seat on a base, and the upper seat plate is provided with a side groove for threading and pulling a zipp...
