Problems solved by technology

[0003] In the existing injection mold, after one side of the slider is inserted into the mold cavity, the slider is usually pressed against the stopper under the action of the spring, which makes the slider likely to be melted when the injection pressure is high. The plastic pushes apart, causing the injection molded parts to fail to form the ideal shape

Abstract

The invention relates to the field of injection molds, in particular to a bolt locking structure which comprises a first sliding block, a second sliding block and a third sliding block. The second sliding block drives the first sliding block and the third sliding block to slide, the oil cylinder and the first sliding block form a sliding block lateral core-pulling mechanism, the second sliding block and the third sliding block form a bolt locking structure, during mold closing, the third sliding block is inserted into the groove so that the first sliding block cannot move, and before mold opening, the third sliding block is inserted into the groove so that the first sliding block cannot move. The oil cylinder drives the second sliding block to drive the third sliding block to be separated from the groove, and then the second sliding block drives the first sliding block to be separated from the mold cavity to complete core pulling, so that the technical problem of how to stabilize the sliding block lateral core pulling mechanism and enable the sliding block lateral core pulling mechanism not to move in the injection molding process is solved.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to a door bolt locking structure. Background technique [0002] There is a slider lateral core-pulling mechanism in the injection mold, which is used to form an undercut structure in the injection molded part. The slider is usually pulled by an inclined guide column or an oil cylinder, so that the slider is separated from the cavity when the mold is opened. , and when the mold is closed, one side of the slider is inserted into the cavity. [0003] In the existing injection mold, after one side of the slider is inserted into the mold cavity, the slider is usually pressed against the stopper under the action of the spring, which makes the slider likely to be melted when the injection pressure is high. The plastic pushes apart, causing the injection molded part to fail to form the ideal shape. [0004] For this reason, a structure is required that can prevent the slider from moving aft...
