[0032] In use, first, the scraping assembly 600 is placed inside the embedding ring 302, and the supporting plate 611 is placed inside the avoiding groove 602, then the lower mold plate 200 is placed on the top of the base 300, and the upper mold plate 100 is placed on the top of the lower mold plate 200, after that, the cover plate 400 is placed on the top of the upper mold plate 100, the blocking piece 904 and the vertical rod 903 are passed through the installation hole 902, the horizontal plate 908 is pushed outward by the handheld handle 915, the horizontal plate 908 is attached to the vertical rod 903 through the U-shaped groove 909, then the threaded rod 907 is screwed, so that the sliding seat 906 and the horizontal plate 908 move upward, and the horizontal plate 908 is tightly pressed on the bottom of the blocking piece 904, so as to ensure the extrusion force between the upper mold plate 100, the lower mold plate 200, the base 300 and the cover plate 400; similarly, the upper mold plate 100, the lower mold plate 200, the base 300 and the cover plate 400 can be disassembled in turn, so that the annular flow channel, the circular cavity and the square groove 103 are exposed, and the scale is easy to clean; The cooling water flows into the outer ring cavity of the circular cavity through the water inlet pipe 500, and drives the groove-shaped seat 603 to rotate, part of the cooling water passes through the gap between the avoiding groove 602, the reinforcing ring two 606 and the reinforcing ring three 608, the gap between the reinforcing ring three 608 and the top wall of the stepped groove 202, and enters the inner ring cavity of the circular cavity, and the groove-shaped seat 603 further drives the cooling water in the inner ring cavity to flow. Through the blocking effect of the groove-shaped seat 603 on the cooling water, the flow time of the cooling water in the circular cavity is prolonged. Then, the cooling water in the circular cavity enters the inside of the annular flow channel through the U-shaped pipe 304 and the L-shaped pipe 205, and through the arrangement of the flow guide assembly 700, the cooling water is branched in the left side of the annular flow channel, flows from left to right in the inside of the annular flow channel, and then converges to the middle of the right side of the annular flow channel. The cooling water enters the straight flow channel through the through hole 105, and finally, the cooling water passes through the S-shaped flow channel and the drain pipe 800 and is discharged.

[0033] During the process that the cooling water drives the groove-shaped seat 603 to slide along the annular guide rail 601, the supporting plate 611 moves synchronously along the annular guide rail 601, when the groove-shaped seat 603 moves to the avoiding groove 602, the spring one 612 is in a free stretching state, the scraper 607 is separated from the top wall of the stepped groove 202, and the cooling water can fully contact with the top wall of the stepped groove 202. After the supporting plate 611 passes through the avoiding groove 602, the spring one 612 is compressed, and the scraper 607 is attached to the top wall of the stepped groove 202. Through the elasticity of the spring one 612, the pressure between the scraper 607 and the top wall of the stepped groove 202 is ensured, so that the scale is removed by scraping the scraper 607 on the top wall of the stepped groove 202, and the heat conduction effect of the cooling water and the mold is ensured.
