Description

A mold undercut demoulding structure

Technical Field

The utility model relates to the technical field of molds, in particular to a mold undercut demoulding structure.

Background Art

Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, molds are tools 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. It is known as the mother of industry. It is a tool that makes the blank become a part of a specific shape and size under the action of external force. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and engineering plastics, rubber, ceramics and other products. In the forming process of compression molding or injection molding, the mold has a specific contour or inner cavity shape. The application of a contour shape with a cutting edge can make the blank separate and punch according to the contour shape. The application of the inner cavity shape can make the blank obtain a corresponding three-dimensional shape. The mold generally includes a movable mold and a fixed mold, or a punch and a die. The two parts can be separated and combined. When separated, the workpiece is taken out, and when closed, the blank is injected into the mold cavity for forming. The mold is a precision tool with a complex shape. It bears the expansion force of the blank. It has high requirements on structural strength, rigidity, surface hardness, surface roughness and processing accuracy. The development level of mold production is one of the important indicators of the level of mechanical manufacturing.

However, it still has some disadvantages. For example, in the production of injection molded products, it is necessary not only to consider the accuracy and precision of the product mold design, so that the product produced by the mold meets the design requirements and is beautiful, but also to ensure that the product can be easily demolded. The demolding process takes a lot of time for the staff, and the product cannot be taken out of the mold quickly, which reduces the work efficiency. The molded product is easily damaged during the demolding process. The injection groove has a unique shape and a small internal space, which makes it difficult to take out the molded product.

In order to solve the above problems, a mold undercut demoulding structure is proposed in the present application.
