Core-pulling mechanism and mold

Abstract

The utility model belongs to injection mould technology field discloses a kind of core-pulling mechanism and mould, in this core-pulling mechanism, rotating member includes rotating body and the mould core of being arranged in rotating body one end, mould core is spirally arranged along the direction of being away from rotating body;One of rotating body and upper die seat is provided with guide slot, and the other is provided with helical guide rail, helical guide rail is arranged in guide slot, rotating member moves along its own axis while rotating around its own axis;Driving assembly is slidably connected with upper die seat, and is connected with rotating body, driving assembly is close to or away from upper die seat to drive rotating body to spiral advance or spiral retreat.After pouring is completed, rotating body moves upward while, it rotates under the cooperation of helical guide rail and guide slot, to drive several mould cores to spiral rise synchronously, to be extracted from respective corresponding helical groove respectively, only driving rotating body is needed in the whole process, reduce the risk of jam, and help to improve assembly efficiency.
