Die system for efficiently producing inner diameter and outer diameter fixed plastic workpiece

Abstract

A die system for efficiently producing an inner diameter and outer diameter fixed plastic workpiece comprises the workpiece, and further comprises a die. The die comprises an upper die body, a lower die body, a die body A and a die body B, wherein an opening is formed in one end of the die body A, a cavity is formed in the die body A, the die body B is arranged in the die body A, and the lower die body is arranged in the die body B and extends out of a lower opening of the die body B. The workpiece is put on an upper opening of the die body A, the outer surface of the workpiece makes close contact with the outer surface of the die body B, and the inner surface of the workpiece makes close contact with the outer surface of the die body B. The upper die body is arranged outside the die body A, and the upper die body moves vertically through a first power mechanism. When the upper die body moves downwards, the die body A contracts inwards. The lower die body can move vertically through a second power mechanism. When the lower die body moves upwards, the die body B expands outwards. The thickness of a gap formed between the die body A and the die body B is the thickness of the machined wall of the workpiece. When the plastic workpiece is machined, part of the plastic workpiece is molten through heating, and required mechanical strength is greatly reduced.

Description

technical field [0001] The invention relates to a mold, in particular to a mold system for efficiently producing plastic workpieces with fixed inner and outer diameters. Background technique [0002] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to shape an object. 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 article through the change of the physical state of the formed material. Known as the "Mother of Industry". [0003] However, when the existing molds are used to prepare plastic workpieces with specific inner and outer diameters, large mechanical forces are required, resulting in processing difficulties. This problem needs to be solved urgently. Contents of the invention ...
