Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy die-casting molds, and in particular to an aluminum alloy die-casting mold with a multi-cavity independent temperature control function. Background Art

[0002] Aluminum alloy is the most widely used type of non-ferrous metal structural material in industry. It has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. Aluminum alloy die-casting molds can be divided into single-cavity molds and multi-cavity molds according to their composition and structure. It is a process completed on a special die-casting forging machine. Its basic process is: the molten metal is first cast and filled into the mold cavity at a low speed or high speed. The mold has a movable cavity surface. It is pressurized and forged as the molten metal cools, which not only eliminates the shrinkage and porosity defects of the blank, but also makes the internal structure of the blank reach the broken grains of the forged state. The comprehensive mechanical properties of the blank are significantly improved; however, the upper mold of the aluminum alloy die-casting mold currently used is moved up and down by a hydraulic cylinder for pressing. Since the hydraulic cylinder often vibrates slightly during pressing, the combination between the upper mold and the lower mold is no longer tight, causing the aluminum alloy melt in the cavity to deform during cooling and forming, and other defects. In addition, the aluminum alloy die-casting mold forms the aluminum alloy parts by natural cooling during the forming process, which wastes time. In addition, the surface of the aluminum alloy parts still has a certain temperature when the mold is removed, which can easily scald the staff. Summary of the invention
