Quickly cooled engine cylinder block die-casting die

Abstract

The invention discloses a quickly cooled engine cylinder block die-casting die. The quickly cooled engine cylinder block die-casting die comprises a moving die base plate, cushion blocks, a supportingplate, a moving die plate, a fixed die plate and a fixed die base plate which are vertically arranged in parallel from left to right in sequence. The outer wall of the moving die base plate is connected with the supporting plate through the cushion blocks. A first water inlet pipe and a second water outlet pipe are arranged at the centers of the top surface and the bottom surface of the supporting plate correspondingly. The end faces, attached to the end faces of the moving die base plate and the supporting plate, of the cushion blocks are provided with through holes. A plurality of telescopic sleeve rods penetrating through the cushion blocks to be connected with the moving die plate are embedded in the moving die base plate. According to the quickly cooled engine cylinder block die-casting die, a first heat dissipation cavity and a second heat dissipation cavity are formed in a spliced mode. Compared with embedded heat dissipation water pipes, the heat dissipation effect of surfaceheat dissipation is better than that of linear heat dissipation, the processing method is simpler and more convenient to implement, the technological steps are fewer, the cost is low, and the production cost of the die can be reduced.

Description

technical field [0001] The invention relates to the technical field of die-casting dies, in particular to a fast-cooling die-casting die for an engine block. Background technique [0002] Die-casting mold is a tool for casting metal parts, a tool that completes the die-casting process on a special die-casting die forging machine. The basic process of die-casting is: the molten metal is first cast at a low or high speed and filled into the cavity of the mold. The mold has a movable cavity surface, which is forged under pressure during the cooling process of the molten metal, which eliminates the shrinkage of the blank. Loose defects also make the internal structure of the blank reach the broken grains of the forged state. The comprehensive mechanical properties of the blank are significantly improved. [0003] Existing die-casting molds radiate heat by embedding heat-dissipating water pipes inside the mould. For mold production, this structure requires complex processes, hi...

Problems solved by technology

[0003] Existing die-casting molds radiate heat by embedding heat-dissipating water pipes inside the mould. For mold production, this structure requires complex processes, high production and manufacturing costs, and the water in the heat-dissipating water pipes is gradually heated along the pipes. , which makes the quality of the product affected by the cooling effect cracks and gaps, affecting the quality of the product
