Description

Technical Field

[0001] The utility model relates to the technical field of die casting moulds, in particular to a die casting mould for a diesel engine body. Background Art

[0002] The die-casting mold is a tool for casting metal parts. It is a tool that completes the die-casting process on a special die-casting forging machine. The basic process of die-casting is: the molten metal is first cast and filled into the mold cavity at a low or high speed. The mold has a movable cavity surface. It is pressurized and forged as the molten metal cools. This not only eliminates the shrinkage defects of the blank, but also makes the internal structure of the blank reach the broken grains in the forged state, and the comprehensive mechanical properties of the blank are significantly improved.

[0003] The existing die-casting for diesel engine body has no cooling structure and needs to be connected to external water supply equipment through pipes to cool the molten metal by cooling water, which is relatively dependent on external equipment. Therefore, we propose a die-casting mold for diesel engine body. Utility Model Content
