Referring to fig. 3 and 5, the cooling pipe includes an output pipe and an input pipe, the cooling member 21 includes an output branch pipe 210 and an input branch pipe 211, the input branch pipe 211 is sleeved outside the output branch pipe 210, a cooling space 212 is formed between an inner wall of the input branch pipe 211 and an outer wall of the output branch pipe 210, and an output end of the input branch pipe 211 is communicated with an input end of the output branch pipe 210. The cooling of the mold core 1 is realized by embedding and installing the output branch pipes 210 and the input branch pipes 211 in the mold core 1, so that the product 5 is shaped, and the working efficiency is improved. The cooling assembly 2 further comprises a power member 22, and the output end of the output branch pipe 210 and the input end of the input branch pipe 211 are respectively connected with the power member 22. In this embodiment, the power member 22 is provided with two power members 22 for supplying water and connected with the input end of the input branch pipe 211, and the power member 22 for pumping water is connected with the output end of the output branch pipe 210. An internal circulation cooling channel is formed, and the cooling efficiency is accelerated.
