The cooling method is simple and the cooling effect is good; the cooling mechanism 4 includes a plurality of cooling pipes 41 evenly arranged on the through groove 5, one end of the cooling pipe 41 is connected to the through groove 5, and the through groove 5 corresponds to each cooling pipe 41 The baffle 42 is provided in each of the cooling tubes 41. The lower end of the baffle 42 is sealed and connected to the through groove 5, and the upper end extends toward the cooling tube 41. The side wall of the baffle 42 is sealed and connected to the cooling tube 41. The cooling tube 41 is provided to flow the liquid so that the liquid can take away the heat and achieve the effect of heat dissipation. The cooling tube 41 is connected to the through groove 5, and the baffle 42 is provided in the cooling tube 41. When the liquid enters the through groove 5 and reaches the first cooling tube 41, the liquid can be blocked by the baffle 42 and guided to enter the cooling tube 41, and then flow out of the cooling tube 41.

The input channel 44, the output channel 45 and the turning channel 43 are connected and arranged. The turning channel 43 is arranged to introduce the liquid from the input channel 44 into the output channel 45, so that the liquid can flow and avoid liquid backflow. In this solution, each cooling tube 41 is provided with an input channel 44, an output channel 45 and a turning channel 43;The through groove 5 has a starting end 51 and a terminal end 52, wherein the starting end 51 is provided with an input pipe 53, and the terminal end 52 is provided with an output pipe 54, wherein a first conduit 55 is provided between the input pipe 53 and the input end 2, and a second conduit 56 is provided between the output pipe 54 and the output end 3, and the input pipe 53 and the output pipe 54 are provided so as to facilitate the input and output positions of the operator, and the first conduit 55 is provided to connect the input pipe 53 with the input end 2, and the second conduit 56 is provided to connect the output pipe 54 with the output end 3, and the first conduit 55 and the second conduit 56 can more conveniently introduce liquid into the cooling pipe 41 or lead out the cooling pipe 41; one end of the first conduit 55 is connected with the input end 2, and the other end is arranged to be inclined upward and connected with the upper end position of the input pipe 53, and one end of the second conduit 56 is connected with the output end 3, and the other end is connected with the lower end of the output pipe 54, and the first conduit 55 is connected to the upper end of the input pipe 53 so as to prevent impurities in the liquid from entering the input pipe 53. As the liquid enters the input pipe 53, impurities in the liquid can be retained at the input end 2 or other positions other than the input pipe 53. By connecting one end of the second conduit 56 to the output end 3 and the other end to the lower end of the output pipe 54 and connecting with it, the output pipe 54 can be more convenient to discharge the liquid. The input end 2 includes a separation tube 21 arranged on the shell 1. The middle part of the separation tube 21 has an input hole 22 that passes through from top to bottom. An output ring 31 that passes through from top to bottom is formed between the outer peripheral wall of the separation tube 21 and the shell 1. The separation tube 21 is arranged on the shell 1. The separation tube 21 can be used to separate the input hole 22 and the output ring 31 to avoid the overlap of the two. The structure is clear and the separation method is simple. The separation tube 21 is placed in the middle of the shell 1. The input hole 22, the separation tube 21 and the output ring 31 are concentrically arranged. The input hole 22, the separation tube 21 and the output ring 31 are concentrically arranged to make the width of the output ring 31 more uniform, and the liquid flows more smoothly in the input hole 22 and the output ring 31.The separation tube 21 is a cylindrical tube with an arc-shaped side wall, and the inner circumferential wall of the output ring 31 is an arc-shaped inner circumferential wall. The inner circumferential wall of the output ring 31 is set to be arc-shaped.

Compared with other polygonal tubes, the liquid in the tube is not easy to be retained in the tube, the fluidity is better, and the structure is simple. When implementing this scheme, those skilled in the art can allow water or coolant or other liquid used for cooling to enter the first conduit 55 through the input end 2 and then enter the input pipe 53 through the first conduit 55. Since the first conduit 55 in this scheme is arranged to be inclined upward toward the top of the input pipe 53, when water passes through the first conduit 55, impurities in the water will not easily flow toward the first conduit 55 with the water due to their own weight. When the water enters the input pipe 53, since the input pipe 53 is connected with the starting end 51 of the through groove 5, the water can enter the through groove 5. At this time Since the technicians in this field will continuously inject water into the input end 2 to input the water source, the water in the through groove 5 can also continuously flow toward the end 52 of the through groove 5. When the water reaches the position of the first cooling tube 41, the water will be blocked by the baffle 42 and surge upward. After continuous water injection, the water can enter the turning channel 43 at the upper end of the baffle 42 through the input channel 44 on one side of the baffle 42, and finally enter the output channel 45 on the other side of the baffle 42, and finally enter the channel, repeating in sequence. The number of repetitions is determined by the number of cooling tubes 41 set by the technicians in this field. The water can pass through each cooling tube 41 and finally reach the output tube 54 from the through groove 5, and then enter the second conduit 56 from the output tube 54, and finally be guided by the second conduit 56 to flow out from the output ring 31. The water can continuously circulate to absorb and dissipate the heat of the mold, and the cooling effect is good. Since the water flows over a long distance, the water flow absorbs more heat, which is more conducive to cooling the mold. ;
