Description

Technical Field

[0001] The invention relates to the technical field of extrusion casting dies, and more particularly to an extrusion casting die for an automobile clutch housing. Background Art

[0002] Automobile clutch housing extrusion casting mold is a process in which molten metal is injected into the mold cavity under high pressure and solidified under pressure. This process can effectively reduce defects such as pores and shrinkage holes inside the casting, improve the density and mechanical properties of the casting, and produce castings with dense structure and high mechanical properties. It can replace some forging to produce high-performance complex structural parts. Therefore, the demand for its mold has also increased accordingly. During the squeeze casting of the automobile clutch housing, after the molten metal is squeezed and shaped, it is necessary to quickly cool the molten metal to shape it. During the cooling process, the molten metal cooling time is long, which reduces the production efficiency of the automobile clutch housing squeeze casting, thereby affecting the operator's experience. During the extrusion casting of automobile clutch housings, when cooling liquid is needed during the cooling process, the molten metal may explode when it comes into contact with the cooling liquid, causing damage to the equipment and threatening the operator's personal safety due to the explosion. When liquid cooling is used in the squeeze casting of automobile clutch housing, the molten metal has high temperature properties, which will cause the temperature of the internal cooling liquid to increase after long-term use of the equipment, thereby reducing the cooling effect and affecting the cooling quality of the equipment.
