Detailed ways

As shown in Figure 1, the utility model discloses a cooling device for processing and forming plastic blades, including a forging table 1 and a cooling pipeline 3, a mold 2 is arranged above the forging table 1, and the forging table 1 and the mold 2 A cooling circuit 12 is provided at the contact point, and the cooling pipeline 3 passes through the upper surface, the lower surface, and the forging table 1 of the mold 2 in sequence, and a first inlet 312 is provided above the cooling pipeline 3, and the cooling pipeline 3 Below the pipe 3 is provided a first outlet 313, the first inlet 312 is connected to the cooling medium delivery pipe, the cooling circuit 12 includes a second inlet 121 and a second outlet 122, the The second inlet 121 is located next to the mold 2, the second outlet 122 communicates with the cooling pipeline 3 located in the forging table 1, and the cooling pipeline 3 is located on the first inlet There are several through holes 311 on the pipe wall on the side, the first outlet 313 is located in the circulation pool 4, and the circulation pump is installed in the circulation pool 4, and the output end of the circulation pump is connected with the cooling medium delivery pipeline. connect. A plurality of diversion holes 11 are opened on the forging table 1 , and the diversion holes 11 are facing the circulation pool 4 . Preferably, the cooling pipeline 3 in this embodiment is located at the center of the mold 2 , there are four cooling circuits 12 , and each cooling circuit 12 is symmetrically distributed around the cooling pipeline 3 .

In this embodiment, the cooling medium in the circulation pool 4 is drawn out by the circulation pump, and a part of the cooling medium enters the cooling pipeline 3 from the cooling medium circulation pipeline through the first inlet 312 to cool the center of the mold, and due to the through hole 311, the cooling medium is sprayed from the through hole on the wall surface of the cooling pipe 3 above the mold to the surface of the mold for cooling, and at the same time, part of the liquid accumulation of the cooling medium sprayed on the forging table 1 flows into the second inlet on the forging table 121, cooling the bottom of the mold through the cooling circuit 12, the cooling medium in the cooling circuit 12 is collected into the cooling passage through the second outlet 122, and finally flows back into the circulation pool 4 through the first outlet 313; The other part of the cooling medium sprayed on the forging table 1 flows back into the circulation pool 4 through the guide hole 11. Through the above process, on the one hand, the inside and outside of the mold are cooled by the cooling medium, so that all parts of the melt The cooling rate is roughly the same, and the shrinkage of the die-casting parts is the same when cooling, which eliminates the problems of internal stress concentration, large deformation and easy cracking after cooling, and improves the hydraulic performance and strength of the impeller. On the other hand, while the cooling medium plays a cooling role, it can finally flow back to the circulation pool for repeated use, which saves costs.
