Description

Mould convenient for demoulding

Technical Field

The utility model relates to the technical field of stamping dies, in particular to a die convenient to demould.

Background

The mould is used for producing various moulds and tools of the needed products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods in industry. In short, a mold is a tool used to make a molded article, which is made up of various parts, with different molds being made up of different parts. The processing of the appearance of the article is realized mainly by changing the physical state of the formed material. The die is a tool for making the blank into a workpiece with a specific shape and size under the action of external force. The method is widely used for blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting and the molding processing of compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The die has a specific contour or cavity shape, and the blank can be separated (blanked) according to the contour shape by using the contour shape with the cutting edge. The blank can obtain a corresponding three-dimensional shape by using the shape of the inner cavity. The mold generally comprises a movable mold and a fixed mold (or a male mold and a female mold), which can be separated and combined. And taking out the workpiece when the workpiece is separated, and injecting the blank into the die cavity for forming when the workpiece is closed. The die is a precise tool, has a complex shape, bears the expansion force of a blank, has higher requirements on structural strength, rigidity, surface hardness, surface roughness and machining precision, and is one of important marks of the mechanical manufacturing level.

At present, after the part is subjected to stamping processing, a finished workpiece is easy to clamp in an inner cavity of a lower die and is difficult to demould, and workers are required to manually demould the workpiece, so that the labor is wasted, and the stamping processing efficiency is influenced; therefore, in order to solve the technical problem, the application provides a mold convenient to demolding.
