The limiter 16 also limits the upper mold 6, so that the docking of the upper mold 6 and the lower mold 3 is more stable. The upper mold 6 is vertically fixed with an introduction pipe 19, and the lower end surface of the introduction pipe 19 is flush with the lower end surface of the upper mold 6. The upper end of the introduction pipe 19 extends to the top of the upper mold 6. The lower mold 3 and the upper mold 6 are respectively fixed with S tubes horizontally, and a water tank 7 is fixedly installed on the upper end surface of the top plate 4. The water tank 7 is connected to one end of the S tube 8 through a conveying mechanism. The end of the S tube 8 away from the conveying mechanism is fixedly connected with a reflux telescopic pipe 9, and the reflux telescopic pipe 9 is fixedly passed through the water tank 7. A cover is provided on the upper part of the water tank 7. The device can inject water into the upper mold 6 or the lower mold 3 by respectively arranging S tubes 8 in the upper mold 6 and the lower mold 3, and use the water flow to take away heat and slow down the shaping and cooling of the raw materials. At the same time, components such as the pump body 11 are arranged to realize the recycling of water, which is convenient and practical.

[0026] Example 2

[0027] like Figure 1 As shown in FIG. 4 , the conveying mechanism includes two pump bodies 11 fixedly mounted on the inner bottom surface of the water storage tank 7. The two pump bodies 11 are fixedly connected with the corresponding S tubes 8 through the conveying telescopic tubes 12 respectively. The conveying telescopic tubes 12 are fixedly penetrated through the side wall of the water storage tank 7. The pump bodies 11 are used to convey water, which enters the S tube through the conveying telescopic tubes 12 and then returns to the water storage tank 9 through the reflux telescopic tube 9.

[0028] Example 3

[0029] like Figure 1-4, the inner bottom surface of the lower mold 3 is laterally slidably matched with an ejection plate 15, and a push plate 13 is laterally arranged below the table 1. A connecting column 14 is vertically fixedly installed on the upper end surface of the push plate 13. The connecting column 14 movably penetrates the table 1 and the lower mold 3. The upper end surface of the connecting column 14 is fixedly connected to the lower end surface of the ejection plate 15. The push plate 13 is made of non-metallic material to ensure that it is a poor conductor of heat, so as to avoid the push plate 13 from being too hot and inconvenient to operate. Pushing the push plate 13 upward can indirectly drive the ejection plate 15 to move, so as to push the product out and facilitate material removal.

[0030] Working principle:

[0031] When in use, the electric push rod 10 is controlled to extend and drive the upper mold 6 to move downward, and the upper mold 6 moves downward to cover the lower mold 3. Then, the high-temperature raw material is injected into the space between the upper mold 6 and the lower mold 3 through the inlet pipe 19. Then, the pump body 11 is controlled to start. The pump body 11 sends the water in the water tank 7 outward, and the water returns to the water tank 7 through the delivery telescopic pipe 12, the S pipe and the reflux telescopic pipe 9. The flowing water takes away the heat in the lower mold 3 and the upper mold 6, and accelerates the shaping and cooling of the raw materials. After cooling, the pump body 11 is closed, and the electric push rod 10 is controlled to shorten and reset to drive the upper mold 6 to move upward and open, and then the push plate 13 is pushed upward, which indirectly drives the push plate 15 to move upward to push out the shaped product.

Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
