The setting of the fixing bolt 305 is that when using the turbocharger housing casting mold to manufacture the turbocharger housing, first start the cylinder 302 to make the upper mold 2 fit tightly with the lower mold 1, then rotate the L-shaped fixing block 304 to get it under the lower mold 1, and then fix it with the fixing bolt 305, and then pour in molten iron and wait for completion, remove the fixing bolt 305 and rotate the L-shaped fixing block 304 to make the L-shaped fixing block 304 detach from the lower mold 1, and then start the cylinder 302 to pull the upper mold 2 to separate it from the lower mold 1, and take out the manufactured turbocharger housing.

[0022] Furthermore, the lower mold 1 fits tightly with the upper mold 2, and the cylinder 302 is symmetrically arranged with respect to the central axis of the outer frame 301. Through the arrangement of the cylinder 302, the upper mold 2 can be better separated from the lower mold 1, and the cylinder 302 drives the upper mold 2 to separate from the lower mold 1.

[0023] Furthermore, the outer wall size of the cylinder 302 matches the inner wall size of the outer frame 301, and the central axis of the mold 2 above the connecting block 303 is symmetrically arranged. Through the arrangement of the outer frame 301, the cylinder 302 can work better and be installed through the outer frame 301.

[0024] Furthermore, the central axis of the mold 2 above the L-shaped fixing block 304 is symmetrically arranged, and the central axis of the mold 2 above the fixing bolt 305 is symmetrically arranged. Through the arrangement of the L-shaped fixing block 304, the lower mold 1 and the upper mold 2 can be fixed more tightly. The L-shaped fixing block 304 fixes the lower mold 1 and the upper mold 2 through the fixing bolt 305.

[0025] Further, the cooling mechanism 4 includes a water inlet 401, an inner cavity 402, a water outlet 403, a connecting pipe 404, a water tank 405 and a cooling machine 406. A water inlet 401 is provided on one side surface of the lower mold 1, an inner cavity 402 is provided on the inner side surface of the lower mold 1, an inner cavity 402 is provided on the inner side surface of the upper mold 2, a water outlet 403 is provided on one side surface of the lower mold 1, a connecting pipe 404 is fixedly connected to one side surface of the water outlet 403, a water tank 405 is fixedly connected to one end surface of the connecting pipe 404, a cooling machine 406 is provided on one side surface of the water tank 405, and a cooling machine 406 is provided on one side surface of the water tank 405. The inner cavity 402, the water outlet 403, the connecting pipe 404, the water tank 405 and the cooler 406 are arranged. During the manufacturing process of the turbocharger housing, the cooler 406 is first started to transport the water with relatively low temperature through the connecting pipe 404, and then enters the inner cavity through the water inlet 401 to quickly cool the molten iron in the mold, and then outputs it through the water outlet 403, and then transported to the water tank 405 through the connecting pipe 404. The water in the water tank 405 is transported to the cooler 406 through the connecting pipe 404 and quickly cooled to a low temperature. In this way, the circulating water cooling can achieve the manufacturing time of the turbocharger housing to quickly cool down.

[0026] Furthermore, the outer wall size of the water inlet 401 matches the inner wall size of the connecting pipe 404, and the outer wall size of the water outlet 403 matches the inner wall size of the connecting pipe 404. Through the setting of the connecting pipe 404, the input and output of water can be more stable. The connecting pipe 404 connects various components.

[0027] Furthermore, the water tank 405 is connected to the cooler 406 via the connecting pipe 404 , and the central axis of the mold 1 below the connecting pipe 404 is symmetrically arranged. Through the arrangement of the water tank 405 , the circulation of water can be more convenient, and the water tank 405 continuously provides circulating water to the cooler 406 .

[0028] Working principle: When using the turbocharger housing casting mold to manufacture the turbocharger housing, first start the cylinder 302 to make the upper mold 2 fit tightly with the lower mold 1, then rotate the L-shaped fixing block 304 to get it under the lower mold 1, and then fix it with the fixing bolt 305, then pour in molten iron and wait for completion, remove the fixing bolt 305 and rotate the L-shaped fixing block 304 to make the L-shaped fixing block 304 separate from the lower mold 1, then start the cylinder 302 to pull the upper mold 2 to separate it from the lower mold 1, and take out the finished mold. In the manufacturing process of the turbocharger housing, the cooler 406 is first started to transport the water with relatively low temperature through the connecting pipe 404, and then enters the inner cavity through the water inlet 401 to quickly cool the molten iron in the mold, and then outputs it through the water outlet 403, and then transported to the water tank 405 through the connecting pipe 404. The water in the water tank 405 is transported to the cooler 406 through the connecting pipe 404 and quickly cooled to a low temperature. In this way, the circulating water cooling reaches the manufacturing time of the turbocharger housing.
