A precision mold for processing plastic products

Abstract

The invention relates to the technical field of plastic processing equipment, and discloses a precision mold for processing plastic products, comprising a movable mold base and a static mold base, a movable mold core is provided in the middle of the bottom surface of the dynamic mold base, and a movable mold core is provided in the middle of the top surface of the static mold base. There is a static mold core, and the inside of the static mold base is rectangular in shape, and four guide columns are movably socketed, and the outer ring of the guide column is movably socketed with a protection spring, and the middle part of the movable mold base is provided with a penetrating injection mold. hole, the inside of the injection hole is movably socketed with a movable plunger, the top of the movable mold base is provided with a guide sleeve matching the guide column, and the inside of the bottom of the static mold base is movably socketed with a push rod, so The outer ring of the ejector rod is movably connected with a return spring, and the inside of the guide sleeve is movably connected with a pressure block. The end of the guide sleeve located inside the movable mold seat is connected with a pressure chamber, and the bottom movable sleeve of the pressure chamber Connected with a pressure block, the mold has high precision and high processing efficiency.

Description

technical field [0001] The invention relates to the technical field of plastic processing equipment, in particular to a precision mold for processing plastic products. Background technique [0002] Plastic products are widely used in today's society. Various plastic products have entered our lives, but because of their own small hardness and rigidity, plastic products must ensure quality clearance during production. Plastic products are mostly produced using Injection molding, that is, using an injection molding machine to inject molten plastic into the mold, and take it out after cooling and solidification to repair burrs, etc. However, there are still some defects in the existing plastic product processing molds: [0003] 1. Inject molten plastic through the injection hole during injection molding. When the cavity in the mold is filled with plastic, it will accumulate. When the injection molding fills the space in the cavity, the injection molding will stop. At this time, ...

Problems solved by technology

[0003] 1. Inject molten plastic through the injection hole during injection molding. When the cavity in the mold is filled with plastic, it will accumulate. When the injection molding fills the space in the cavity, the injection molding will stop. At this time, it is only a temporary guarantee. The cavity is filled, but in fact the plastic will cool and the volume will decrease, and the density of the filled plastic is low at this time, which cannot meet the qualified plastic quantity and plastic density, so the produced plastic products cannot guarantee the qualified degree;

[0004] 2. Injection molding is carried out through the injection molding hole, and the plastic in the injection molding hole is also solidified after the injection molding is completed. It is necessary to subsequently remove the section of plastic formed in the injection molding hole. The subsequent removal is not only a waste of time but also cannot guarantee the certainty of the removal. It is accurate, and at the same time, it will also cause waste of plastic, and the production efficiency is not high
