Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy die casting technology, specifically to an aluminum alloy die casting mold. Background Technology

[0002] Aluminum alloy die-casting molds are precision, complex, and heat-resistant steel tools. Under high pressure, molten aluminum alloy is injected at high speed into the mold cavity, rapidly cooled, and then ejected to form the desired shape and size of the die-cast aluminum alloy part. The die-casting process, with pressure forging applied as the molten metal cools, has the advantages of eliminating shrinkage cavities and porosity defects in the blank and achieving a forged, fragmented grain structure within the blank.

[0003] Chinese patent application CN202321304148.5 discloses an aluminum alloy die-casting mold, including a mounting frame. Support rods are mounted at the four corners of the top of the mounting frame, and a fixing plate is mounted on the top of each support rod. Drive motors are mounted on both sides of the inner bottom wall of the mounting frame, and threaded rods are mounted on the top of the output shafts of the drive motors. Movable mechanisms are mounted on both sides of the bottom of the fixing plate, and the tops of the threaded rods are connected to the movable mechanisms. This device allows for mold installation and replacement; however, it is only suitable for molds of fixed sizes and cannot be adjusted to fit different mold dimensions, making it inconvenient to use.
