Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a slide block pre-pressing needle anti-insertion component deflection structure. Background Art

[0002] A mold is a tool used to make molded products. Products of different shapes can be made by using different shapes of molds. The internal circumference of the mold in the related technology has undercuts, and a sloping top structure is generally used to facilitate demolding. A mold is a variety of molds and tools used in industrial production for injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods to obtain the required products. A mold is a tool used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material.

[0003] Most of the inserts inside the existing injection molds are in a suspended state inside the mold. During the injection filling process, the inserts may be affected by the injection material and may shift left or right or swing, resulting in errors in the injection molded products, causing defects in the injection molded products that affect their appearance. At the same time, it also increases the amount of damage to the injection molded products and increases the cost of injection mold processing.

The inserts can be clamped and limited by the supporting mechanism during injection molding, which can prevent the inserts from shaking left and right during the injection molding process, causing the injection molded product to deviate and become unusable, and at the same time, the position of the insert body needs to be adjusted for injection molding again, which reduces the workload of the staff, avoids waste of resources, and is also convenient for the later disassembly, replacement or installation of internal parts.
