Description

Technical Field

[0001] This utility model relates to the field of die casting mold technology, and in particular to a surface treatment device for die casting molds before coating. Background Technology

[0002] Die casting molds are key tools used in the die casting process to form metal products. Liquid or semi-solid metal is injected into the mold cavity under high pressure, and after cooling and solidification, high-precision, complex-structured parts are obtained. The die casting mold is the core component of the die casting machine, consisting of a fixed mold (stationary mold) and a movable mold (moving mold). The mold is closed to form a closed cavity. Under high pressure, molten metal (such as aluminum alloy or zinc alloy) fills the cavity at high speed. After cooling, the mold is opened and the casting is removed. Surface treatment of the die casting mold before coating is a key step to ensure the coating quality and mold performance. It requires operations such as deburring, grinding and polishing, and chemical cleaning to provide a clean and flat base for the coating.

[0003] Before coating a mold, the inner hole of the mold needs to be polished. Common mold inner hole diameters on the market vary. Traditional equipment uses a fixed polishing head, which is only suitable for a single inner hole diameter. Multiple polishing heads are required for different inner hole diameters, which increases costs. Therefore, a surface treatment equipment for die casting molds before coating is proposed.

The distance between the placement plate 102 and the workbench 1 allows the adjustment rod 4 to move down to the maximum distance. The placement plate 102 and the workbench 1 are provided with space for the full stroke of the adjustment rod 4 to avoid equipment interference.

[0035] The process of using the surface treatment equipment for die casting mold before coating provided by this utility model is as follows: According to the inner hole diameter specification of the mold, select the corresponding positioning hole 7 height, slide the slider 62 of the inner hole treatment part 6 along the slide groove 5 to the target positioning hole 7 height, and achieve rigid locking by the positioning bolt 8 through the grinding block 63 and the positioning hole 7, and confirm that the outer end of the positioning bolt 8 is embedded in the hidden groove 9 of the grinding block 63 to avoid interference with the inner wall of the mold.
