Description

Technical Field

[0001] The utility model belongs to the technical field of die-casting molds, and in particular relates to a die-casting mold which is convenient for mold opening. Background Art

[0002] A die-casting mold is a tool for casting metal parts, a tool that completes the die-casting process on a dedicated 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 speed or high speed. The mold has a movable cavity surface. It is pressurized and forged with the cooling process of the molten metal, which not only eliminates the shrinkage and shrinkage defects of the blank, but also makes the internal structure of the blank reach the broken grains of the forged state. For example, an easily disassembled die-casting mold with application number 202321899736.8 includes a front mold frame bottom plate, a front mold core, a rear mold frame, a rear mold core and a rear mold frame base. The front mold core is installed on the bottom side of the front mold frame bottom plate, and the rear mold frame is arranged on the bottom side of the front mold frame bottom plate. The rear mold core is installed on the surface of the rear mold frame close to the front mold core, and the main flow channel is installed through the surface of the front mold frame bottom plate. In the die-casting mold, the fixed plug rod can be pulled out from the inside of the positioning block under tension, and then the bolts between the fixed sleeve and the rear mold frame can be rotated. When the bolts are removed, the connecting plate can be pulled, and the connecting plate can be driven by tension to move the fixed sleeve laterally, so that the positioning block can be removed. After the positioning block is removed, the rear mold core can be removed and replaced.

[0003] Although the above-mentioned die-casting mold can realize convenient disassembly and replacement of the mold core, it has the following defects: (1) During the die-casting molding process, the workpiece of the existing die-casting mold is easily attached to the inner wall of the mold during the cooling and molding process, and it is not easy to separate the workpiece from the inner wall of the mold during the mold opening process, and thus the workpiece needs to be manually processed to separate it from the mold, resulting in the problem of inconvenience in opening the die-casting mold. For this reason, we propose a die-casting mold that is easy to open. Utility Model Content
