Injection mold and demolding mechanism thereof

Abstract

The invention belongs to the technical field of injection molding product demolding and provides an injection mold and a demolding mechanism thereof. The demolding mechanism comprises a mold core component, an oblique jacking seat, elastic oblique jacking swing rods and a supporting block assembly; the oblique jacking seat can move relative to the mold core in a mold opening and closing direction;each oblique jacking swing rod comprises an oblique jacking head part, an oblique jacking foot part and an oblique jacking body part; the supporting block assembly comprises a guiding middle plate and supporting side plates; sliding spaces for the oblique jacking body parts to slide are formed between the guiding middle plate and the supporting side plates; a first contact surface is formed on each oblique jacking body part; a first contact matching surface is formed on the surface of one side, facing the guiding middle plate, of each supporting side plate; and the first contact matching surfaces are used for abutting against the first contact surfaces during mold opening so as to drive the oblique jacking head parts to swing towards one side of the guiding middle plate. Compared with theprior art, the demolding mechanism provided by the invention has the advantages of simple structure, small occupied mold space, high applicability, convenient disassembly and assembly and low manufacturing cost, and has product ejecting, demolding and core pulling functions.

Description

technical field [0001] The invention relates to the technical field of ejection of injection molded products, in particular to an injection mold and an ejection mechanism thereof. Background technique [0002] At present, for plastic products with internal structures such as undercuts and buckles, the inclined roof structure is generally used to release the mold. The inclined roof design is relatively simple in process and low in cost. The inclined top pushes forward obliquely along a certain angle. When the inclined top travels forward for a certain distance, the position of the buckle is separated from the inner contact of the plastic product, so that the plastic product can be taken out smoothly. However, the injection mold with inclined top takes up a lot of space, high cost and complicated installation.
