Extrusion casting die

Abstract

The invention discloses an extrusion casting die, which comprises an upper template, a male die, a female die, a casting, bolts, a lower pressing head, a lower die seat and a pull rod, wherein the female die and the lower die seat are fastened through the bolts; the pull rod is arranged on the lower die seat in a penetrating way; the lower pressing head is arranged at one end of the pull rod; the female die is arranged on the outer side of the lower pressing head; the male die is arranged between the female die and the upper template; and the casting is arranged between the male die and the lower pressing head. By using the extrusion casting die, a casting product is relatively high in comprehensive performance, relatively high in precision, and relatively low in allowance and the surface of the casting product is relatively smooth.

Description

technical field [0001] The invention relates to a extrusion casting mold. Background technique [0002] Casting is a relatively economical blank forming method, and it can show its economical efficiency for parts with complex shapes. Such as the cylinder block and cylinder head of automobile engine, ship propeller and exquisite artwork. In addition, the size and weight of cast parts can be adapted to a wide range, and the types of metals are almost unlimited. While the parts have general mechanical properties, they also have comprehensive properties such as wear resistance, corrosion resistance, and shock absorption. This is another metal forming method. Forging, rolling, welding, punching, etc. cannot be done, so the number and tonnage of rough parts produced by casting in the machine manufacturing industry are still the largest so far. However, during the molding process of die castings, due to the incomplete filling of some parts, when the undercast parts are serious, ...

AI Technical Summary

Problems solved by technology

However, during the molding process of die castings, due to the incomplete filling of some parts, when the undercast parts are serious, the shape of the castings does not meet the requirements of the drawings. At the same time, due to the large shrinkage of the castings during the die casting process, resulting Stresses that cause tearing of the casting and, during solidification of the casting, dark, irregularly shaped keyholes due to insufficient metal compensation
