Delay forced de-molding mechanism of injection mold

Abstract

The invention discloses a delay forced demolding mechanism of an injection mold. The mechanism comprises a pellet (1), a pellet pull rod (2), a limited block (21) and a delay slipway (3). The technical scheme of the invention is that: in a demolding process, a product carrier rod ejects a mold core part of a coated pellet out of a movable mold core forward along with a product and the limiting block limited by the delay slipway prevents the pellet from moving forward by pulling; and the mold core part of the pellet is forcibly extracted from a product inverted buckle position under the actionof the elasticity of a product inverted buckle in the continuous demolding process of the product. Therefore, the problems of high labor force, high working intensity, low efficiency, high cost and accident potential existing in the prior art are solved. The provided delay forced demolding mechanism of the injection mold allows the injection mold of an injection molding product at an inverted buckle clamping position to realize automatic demolding and fulfills the aims of reducing labor force, lowering working intensity, improving production efficiency, lowering cost and eliminating the accident potential.

Description

technical field [0001] The invention relates to a demoulding mechanism of an injection mold, and specifically refers to a time-delayed forced demoulding mechanism of an injection mold that is applied to a movable mold part of an injection mold and is used to force a core block out of an injection molded product. Background technique [0002] The undercut jaws of some injection molding products are difficult to demould because the inside and outside are covered in the mold core. For example, the demoulding of the jaws of automobile trunking products, the prior art adopts the method of core demoulding , that is, during injection molding, the core block is manually embedded in the dynamic model core to participate in the molding, and the core block is ejected together with the product when demoulding, and then the core block is manually extracted from the product, and so on. In actual production Multiple core blocks are usually prepared for turnover. The production of the core...

AI Technical Summary

Problems solved by technology

The production of the core block method must be manned, which requires a lot of labor and high work intensity; manual placement of the core block takes time, resulting in low production efficiency and high overall costs; if the manual placement of the core block is not in place, destructive accidents will occur. Manual placement of inlays will cause work-related accidents if the injection molding machine accidentally moves; therefore, the existing technology has problems and deficiencies such as high manpower occupation, high work intensity, low efficiency, high cost, and hidden dangers of accidents.
