Auxiliary positioning device for plastic steel left-right insertion injection molding

The utility model provides an auxiliary positioning device for plastic steel left-right insertion injection molding. The auxiliary positioning device comprises a left-right insertion injection molding mechanism, a zipper clamping mechanism and a driving mechanism which are arranged in sequence, a limiting step is formed on the left-right insertion injection molding mechanism; the zipper clamping mechanism is connected with a driving mechanism, and the driving mechanism drives the zipper clamping mechanism to move so that zipper teeth at one end of the zipper can abut against the limiting step. The auxiliary positioning device has the advantages that the auxiliary positioning device can correct the distance between the upper stopper and the zipper teeth in the zipper, so that the distance is not too large, the purpose of assisting the positioning of the upper stopper is achieved, and the product quality is improved. 本实用新型提供了一种塑钢左右插注塑的辅助定位装置，包括依次设置的左右插注塑机构、拉链夹紧机构和驱动机构；所述左右插注塑机构上形成有限位台阶；所述拉链夹紧机构与驱动机构相连接，所述驱动机构驱使
