Plastic stool injection mold base for preventing reinforcing ribs from dragging damage during demolding

Abstract

The invention discloses a plastic stool injection mold for preventing reinforcing ribs from dragging damage during demolding. The plastic stool injection mold base structurally comprises a plastic mold shell board, a bolt column, an ejector sleeve ejector, two base cushion blocks, a pedestal, two torsion spring columns and a liner, wherein the two base cushion blocks are attached to the lower leftcorner and the lower right corner of the ejector sleeve ejector separately, the two torsion spring columns are inserted and embedded at the upper left corner and the upper right corner of the liner separately. The plastic mold shell board and the ejector sleeve ejector cooperate, a worker performs pushing and pressing with a thick push rod and a thin push rod of a bevel adjuster, the thick push rod is used for making a rotary lug plate to jack the front end of a sliding plate of a spring seat to tilt so as to push a finished product out, the effect of flexibly adjusting the inclination is achieved, and then the thin push rod pushes a steel reed pipe to balance the rear end of the sliding plate so as to prevent scratch loss, so that a linkage connection rod push frame has upward acting force on the plastic mold shell board in an ejector sleeve body, a product is discharged out of a mold with the inclination of the front side being well controlled, then the rear side is integrally jacked to lift the mold, the product protection effect of the mold is improved, and the stability of product quality is optimized.

Description

technical field [0001] The invention relates to an injection molding mold base for a plastic stool based on the anti-damage of reinforcing ribs when ejected from the mold, and belongs to the field of injection molds. Background technique [0002] The plastic stool injection molding mold has a long stool, so the mold base pushes the bumps higher, which is convenient to take out the mold, and in the pressurization process of the injection molding, it also matches the template polishing and covers the injection molding, so the molded plastic mold has sharp edges and corners It is very delicate and beautiful, but the gap between the formed stool legs and the ribs is long, so that the draft angle is not enough and it is easy to be scratched. The shortcomings of the current technology that need to be optimized are: [0003] Because the draft angle of the injection mold is not enough, it will cause local collapse and deformation of the mold, so that the side wall of the molded part...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a plastic stool injection molding mold base based on preventing ribs from being dragged out of the mold, so as to solve the problem of partial collapse of the mold due to insufficient draft angle of the injection mold. Deformation, so that the side wall of the molded part rubs against the mold when the mold is ejected, because the steel surface of the side wall has burrs and is very rough, and the mold is tilted and scratched when the mold is ejected, causing fire patterns, skin patterns and other wear and tear patterns on the molded parts, resulting in unqualified injection molded products, stools Thickness is reduced and the stool is unstable
