The heat dissipation copper tube 62 and the water inside it are used to conduct the heat of the lower mold 1 to reduce the temperature of the lower mold 1. The end of the drive shaft 5 away from the bidirectional motor 4 passes through the lower mold 1 and is fixedly installed A turntable 63 is installed, and the driving shaft 5 is rotatably connected to the penetration point of the lower mold 1.

When the latch 67 is in contact with the inner wall of the sleeve rod 66, it moves up and down, and squeezes the sleeve rod 66 back and forth, causing the sleeve rod 66 to swing back and forth, thereby causing the sleeve rod 66 to drive the water inlet pipe 61 to rotate back and forth, and the reciprocating rotation of the water inlet pipe 61 can drive the water spray pipe 64 to swing back and forth, and the reciprocating swing of the water spray pipe 64 can increase the spraying area of ​​the atomizing nozzle 65, so that the water mist sprayed by the atomizing nozzle 65 can be evenly sprayed on the outside of the lower mold 1 and the upper mold 2, thereby improving the cooling effect of the upper mold 2 and the lower mold 1, and through the cooperation of the heat dissipation copper tube 62 and the atomizing nozzle 65, the inside and outside of the lower mold 1 can be cooled synchronously, avoiding the situation where the temperature inside and outside of the lower mold 1 are different.

[0030] When the driving shaft 5 rotates, it will drive the driving bevel gear 71 to rotate synchronously. When the driving bevel gear 71 rotates, it cooperates with the forward bevel gear 74 and the reverse bevel gear 76 that are meshed with it, so that the forward shaft 72 and the reverse shaft 75 can rotate synchronously in opposite directions, so that the forward fan 73 and the reverse fan 77 can rotate synchronously in opposite directions. The rotation of the forward fan 73 can draw the external cold air into the interior of the lower mold 1 through the through groove 3 to cool the interior of the lower mold 1. At the same time, the rotation of the reverse fan 77 can draw the heat inside the lower mold 1 out through the through groove 3.
