The four liquid inlet channels 83 are respectively located above the four liquid outlet channels 84.

The top ends of the drain pipes 87 pass through the second liquid inlet holes 86 and extend into the cooling chambers 71.

[0046] The specific injection molding process of the mold of this application is as follows:

[0047] The injection molding machine first controls the mold to close the mold so that the molding blocks 7 are respectively inserted into the injection holes 42 , and a first molding cavity 101 for molding the tube body 92 is formed between the molding blocks 7 and the injection holes 42 , and a second molding cavity 102 for molding the plate body 91 is formed between the groove 61 and the second panel 5 .

[0048] Then the injection molding machine starts to inject hot flow plastic into the hot runner 13. After receiving the hot flow plastic, the hot runner 13 injects the hot melt plastic into a number of flow grooves 41. Then the hot melt plastic will flow into a number of injection holes 42. The hot melt plastic in the injection holes 42 of the runner will flow into the molding cavities between the molding blocks 7 and the injection holes 42, thereby realizing the simultaneous injection molding of a number of tube bodies 92. After the hot flow plastic fills the molding cavity of the tube body 92, it will flow into the groove 61 to form the plate body 91.

[0049] After the product injection molding is completed, cold water is injected into the two first infusion ports 232 through an external pipeline. The cold water entering the two first infusion ports 232 will enter the two annular cooling grooves 62. After passing through the annular cooling grooves 62, the cooling water will flow out from the two first discharge ports 233. When the cooling water flows, the temperature of the third panel 6 will be reduced, thereby improving the cooling effect of the third panel 6 on the product and shortening the cooling time of the product.

[0050] When injecting cold water into the first infusion port 232, it is also necessary to inject cold water into the eight second infusion ports 234. The cold water entering the eight second infusion ports 234 will pass through the eight third infusion ports 64, and then enter the eight liquid inlet channels 83 from the eight third infusion ports 64, and then the cooling water will enter the eight groups of first liquid inlet holes 81 through the eight liquid inlet channels 83, and then flow into the cooling chambers 71 through the eight groups of second liquid inlet holes 86 to cool the tube bodies 92, and then the cooling water will flow into the eight groups of connecting holes 85 through the several drain pipes 87, and then flow into the eight groups of first liquid outlet holes 82 through the eight groups of first liquid outlet holes 82, and then be uniformly collected into the eight liquid outlet channels through the eight groups of first liquid outlet holes 82 and discharged from the mold through the eight second drain ports 235.

[0051] After the product is cooled, the injection molding machine controls the upper mold body 1 and the lower mold body 2 to separate, and then controls the two top plates to move toward the upper mold body 1. When the two top plates move, they will drive a number of ejectors to move, and when the ejectors move, the two molded products will be ejected from the two third panels 6. After the two products are ejected, the injection molding machine will control the upper mold body 1 and the lower mold body 2 to close the mold for a new round of injection molding production of two products.

[0052] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
