[0038] Example 2

[0039] like Figure 1 to Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that mounting holes 10 are opened at the four corners of the upper surface of the base plate 1, and the inner wall of each mounting hole 10 is threadedly connected with a mounting bolt 11.

[0043] Working principle: When the device is in use, the raw materials must first be added to the storage box 2 through the feed barrel 14, and then transported to the plasticizing box 3 for plasticization, and finally transported to the extrusion box 4 for extrusion molding. At the same time, the material inside the extrusion box 4 can be cooled by the cooling mechanism 5, and the coolant inside the water tank 501 can be transported to the inside of the circulating water pipe 503 through the first water pump 502. The coolant flowing through the circulating water pipe 503 can absorb the temperature of the raw materials. Then, the coolant will be transported to the inside of the infusion pipe 507 through the second water pump 505, so that it can be sprayed out through the nozzle 508, which can achieve the purpose of cooling. At the same time, the coolant that absorbs the temperature can be transported to the inside of the water tank 501 through the third water pump 509, and then the rotating motor 5010 is started. The rotating motor 5010 can drive the stirring rod 5011 to rotate, thereby achieving the purpose of stirring the coolant, increasing the contact area between the coolant and the air, and reducing the temperature of the coolant faster, which can ensure the cooling effect of the device on the raw materials and effectively increase the practicality of the device.
