[0007] As a preferred embodiment, the bottoms of both sides of the mold base are provided with a plurality of installation slots, and the plurality of installation slots are evenly distributed.

[0008] As a preferred embodiment, four positioning columns distributed in a matrix are fixedly connected to the top surface of the mold base, and four positioning holes matched with the positioning columns are opened on the lower mold.

[0009] As a preferred embodiment, both sides of the mold base are fixedly connected with support rods, and both ends of the U-shaped frame are slidably sleeved on the support rods.

[0010] As a preferred embodiment, through holes are provided at the four corners of the top surface of the mold base, and the U-shaped frame slides through the through holes.

[0011] As a preferred implementation, a fastening bolt is inserted into the upper end of the U-shaped frame, and the fixing block is fixedly mounted to the U-shaped frame by the fastening bolt.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The PCM color-coated plate refrigerator frame stamping forming die has positioning posts and positioning holes. When installing the lower die, the positioning holes of the lower die can be aligned with the positioning posts on the die base, so that the positioning posts are inserted into the positioning holes, and the lower die can be quickly positioned.

[0014] The PCM color-coated plate refrigerator frame stamping mold is provided with a fixing groove and a fixing component. When the lower mold is placed on the mold base for positioning, each fixing groove will be located directly below the corresponding fixing block. The knob can be rotated to drive the screw to rotate, and the U-shaped frame is driven by the screw to slide vertically along the screw, so that the U-shaped frame drives the fixing block to descend, so that the fixing block enters the fixing groove and presses the bottom wall of the fixing groove, so that the lower mold can be fixed on the mold base. When disassembling, it is only necessary to rotate the knob in the opposite direction to raise the fixing block from the fixing groove, which facilitates the disassembly, assembly and replacement of the lower mold.
