Problems solved by technology
The process of inserting the last chain element into the denture requires extremely high operating precision, and a slight deviation will cause a tooth smashing failure. At the same time, the setting of the denture also causes the leakage of injection molding raw materials, resulting in a waste of raw materials

The invention belongs to the field of a zipper manufacturing device, and particularly relates to a zipper injection molding machine for producing an injection molding zipper. The invention discloses a zipper injection molding machine which is used for molding zipper teeth on a zipper belt so as to produce the injection molding zipper. The zipper injection molding machine is characterized by comprising a worktable, an injection molding main machine, a conveying device and a pull-back device, wherein the injection molding main machine comprises a lower mold, an upper mold and a drive mechanism, the upper mold and the lower mold are arranged along the advancing direction of the zipper belt, and two end edges are respectively provided with a stop block; the conveying device comprises a guide mechanism, a limiting mechanism and a moving mechanism, the guide mechanism comprises a guide roller and a buffer mechanism, the moving mechanism can drive the chain belt to move along the advancing direction; the pull-back device comprises a base, a crank and a movable guide roller, the movable guide roller is rotatably connected to the base by virtue of the crank, when the movable guide roller rotates, pressure can be applied to the chain belt, and the chain belt can be pulled back. The zipper formed by the zipper injection molding machine is uniform and continuous in zipper teeth and capable of saving the injection molding raw materials.
Description
technical field [0001] The invention belongs to the field of zipper manufacturing equipment, and in particular relates to a zipper injection molding machine for producing injection zippers. Background technique [0002] Zippers mainly include metal zippers, nylon zippers and injection molded zippers. Injection molded zippers are widely popular due to their low cost and good performance. The zipper injection molding machine mainly includes a conveying device and an injection molding host. The conveying device is used to move the chain belt of the zipper, and the injection molding host is used to inject and form the chain elements on the chain belt and obtain the finished zipper. [0003] The main problems that need to be solved for injection molded zippers include the uniformity of chain teeth, the continuity of zippers and the saving of injection molding raw materials. The industry has better solved the problem of the uniformity of the chain teeth by setting a buffer mechan...
