[0038] The following is a detailed description of the working principle of the photovoltaic equipment module base extrusion die.

[0039] like Figure 1-7As shown, when the photovoltaic device module base is extruded, the metal sheet is first placed on the surface of the lower mold 52, and then the hydraulic cylinder 31 is started. Under the action of the hydraulic cylinder 31, the lower pressure plate 35 moves downward, thereby driving the hot pressing upper mold 45 to move downward and contact the metal sheet. Then, under the pressure of the hot pressing upper mold 45, the metal sheet is deformed. At the same time, during the downward pressing process, the heating block 1 46 and the heating block 2 53 heat the hot pressing upper mold 45 and the lower mold 52, and then the mold heats the metal sheet to improve the plasticity of the metal sheet, so that the metal sheet is not easy to rebound after extrusion molding. After extrusion molding, the hot pressing upper mold 45 moves upward, and under the action of the motor 41, the rotating roller 42 drives the hot pressing upper mold 45 to rotate, so that the hot pressing upper mold 45 rotates to the top of the rotating roller 42, and the cooling upper mold 411 rotates to the bottom of the rotating roller 42. Then, under the action of the infusion pump 419, The liquid nitrogen in the liquid storage tank 418 is injected into the cooling chamber 414 along the infusion hose 417.

Then, the hydraulic cylinder 31 is started again to make the cooling upper mold 411 contact with the extruded base, thereby cooling the extruded base, so that it can be cooled quickly, shortening the processing cycle and increasing the processing efficiency. At the same time, the cooling upper mold 411 and the hot pressing upper mold 45 are connected to the connecting plate 1 43 and the connecting plate 2 49 through the block 1 44 and the block 2 410, which makes it more convenient to replace the mold. The setting of the spring 2 48 and the spring 3 413 makes the top plate 1 47 and the top plate 2 412 pressed against the surface of the hot pressing upper mold 45 and the cooling upper mold 411, thereby fixing the hot pressing upper mold 45 and the cooling upper mold 411 to prevent them from shaking during the flipping process, making them more convenient to use.
