Abstract
The utility model provides an injection mold with a core-pulling mechanism driven by mold opening and closing, which can resolve problems that when utilizing routine core pulling methods such as lifting to pull cores to overcome internal under-cut of products, core-pulling mechanisms which adopt hydraulic cylinders to pull cores from the lower sides of the products are complicated in structure, high in cost, poor in stability and the like. The technical scheme includes that a driving slide block is slidably connected with a movable plate of the mold, a sliding direction of the driving slide block is perpendicular to an opening direction of the mold, at least one side of the front end of the driving slide block is wedged, and a driven slide block which is inserted into an insert and provided with a wedged end face slidably matches with the driving slide block via an inclined slideway. The injection mold core pulling mechanism utilizes an angle pin to drive the slide block when in mold opening and closing, and completes core pulling action in a direction perpendicular to the mold opening and closing direction, thereby resolving the problem of internal under-cut. Further, the injection mold has simple structure, low cost, fine stability and short injection molding period.
