Description

A new type of in-mold clapping device

technical field

The utility model relates to a mold, in particular to a novel in-mold clapping device.

Background technique

With the continuous progress of society, people are now inseparable from industry. The development of industry has driven the rapid development of society, and industry has also driven the development of machinery manufacturing, and molds play a vital role in the industrial age. 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 make shaped 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 article through the change of the physical state of the formed material. Known as the "Mother of Industry".

Under the action of external force, the blank becomes a tool with a specific shape and size. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or cavity shape, and the application of a contour shape with a cutting edge can separate the blank according to the contour line shape (punching). Applying the shape of the inner cavity can make the blank obtain the corresponding three-dimensional shape. The mold generally includes two parts, the movable mold and the fixed mold (or punch and die), which can be separated or combined. Take out the parts when they are separated, and inject the blank into the mold cavity to form when they are closed. The mold is a precision tool with a complex shape and bears the bulging force of the billet. It has high requirements for structural strength, stiffness, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important symbols of the level of mechanical manufacturing.

At present, the existing molds used in the past mold processing adopt ordinary surface pressing technology. Although the ordinary surface pressing structure can also be made in the process of surface pressing, the size of the products produced by the ordinary surface pressing structure is unstable.
