Inclined pin installing structure for ejection molding mold

Abstract

The invention discloses an inclined pin installing structure for an ejection molding mold, comprising a male-mold core, an inclined pin and a sliding block, wherein the inclined pin and the sliding block are arranged on the male-mold core; the male-mold core is provided with a cavity; one end of the inclined pin is arranged in the cavity, and the other end of the inclined pin is provided with an inclined pin seat; a positioning step is arranged between the inclined pin and the sliding block and comprises a base and two clamping parts which are arranged on the base and are used for positioning the sliding block and the inclined pin respectively; and the two sides of the two clamping parts are respectively provided with a sliding rail. The inclined pin installing structure disclosed by the invention has the advantages that a formed product is ejected by the inclined pin and the positioning step is used for positioning, so that burrs of the formed product caused by simultaneous breaking of the sliding block and the inclined pin are avoided, and the phenomena of fracture, bending and clamping and the like of the existing ejection pin are overcome; uniform ejecting force acts on the formed product, the demolding can be ensured, the fracture of the formed product is reduced, and no marks remain on the appearance of the formed product; and the structure is simple and reasonable, the stability is high, and the demolding faults such as fracture and scratch of the formed product are avoided.

Description

technical field [0001] The invention relates to an ejector part of an injection molding die, in particular to an installation structure of an inclined pin for an injection molding die. Background technique [0002] The structure of the mold for injection molding is changeable. Different gate forms, different ejection methods and different mold structures can form various types of mold forms. Therefore, it is quite difficult to clearly classify the molds. Hereby Generally, the commonly used classification methods can be simply distinguished according to the mold structure, two-plate mold, three-plate mold, no-runner mold and reverse injection mold. When the mold injects the molded product, the injection action is completed, the material filled in the molding space is cooled and solidified, and then the molded product is ejected. At this time, the fixed side and the movable side of the molding machine open the stroke, and the mold is separated by the parting surface. Start fo...

AI Technical Summary

Problems solved by technology

[0003] The ejection of the molded product depends on the molding material, the shape of the molded product, and the structure of the mold. When ejecting, it is best not to crack, scratch, etc., and it must be demolded with few failures. However, the most frequent failure of the existing mold is It is the ejector mechanism, if the ejector pin is broken, bent, stuck, etc., it must be easy to repair or replace, which affects the effect of demoulding and affects the efficiency of production, and the oblique pin has a hook, which is on the product If there is an undercut surface in the exit direction, there is a slider on the side, and if the oblique pin has insufficient space in the exit direction, it is easy to cause the slider and the oblique pin to break the molded product at the same time, causing burrs, which also affects the demoulding and quality of the product
