[0026] When the injection mold is to be demoulded, hot-melt plastic raw materials are first injected into the mold core 17 through the injection port 14, and then coolant is input into the cooling pipe 5 to accelerate the cooling of the injection molded part in the mold core 17. After the injection molded part is cooled, the demoulding cylinder 13 is started to drive the lower template 15 to move downward until the ejector pin 19 is ejected from the mold core 17 by the ejector column 10, thereby ejecting the injection molded part in the mold core 17. This demoulding method is convenient and fast, which not only reduces the time waiting for the injection molded part to cool down, but also allows the injection molded part to be demoulded without disassembling the mold.

[0027] Embodiment 2

[0028] On the basis of the first embodiment, in order to make the injection molded parts in the mold core 17 cool faster, a water supply seat 2 is provided and fixedly connected to one side of the upper surface of the base 1, a pump 3 is provided in the front end of the water supply seat 2, one end of the return pipe 4 is fixedly connected to the rear end of the water supply seat 2, and the other end of the return pipe 4 is fixedly connected to the side of the heat sink 6, one end of the cooling pipe 5 is fixedly connected to the front end of the water supply seat 2, and the other end of the cooling pipe 5 is fixedly connected to the surface of the heat sink 6, the middle section of the cooling pipe 5 is buried in the mold core 17, the heat sink 6 is fixedly connected to one side of the upper surface of the base 1, an air inlet 7 is provided in the heat sink 6, a fan frame 8 is provided on the upper surface of the heat sink 6, and a heat sink 9 is provided in the fan frame 8;

Then the heat dissipation fan 9 in the fan frame 8 is started. The heat dissipation fan 9 drives the air to flow through the air inlet duct 7 to dissipate the heat carried by the coolant. The cooled coolant then flows into the water supply seat 2 through the return pipe 4 to perform continuous circulation cooling for the mold core 17 and the injection molded parts in the mold core 17. This cooling method is convenient and fast, and can also reduce the time waiting for the injection molded parts to cool, thereby improving the demoulding efficiency of the injection molded parts.

Under the action of the ejector post 10, the demoulding plate 18 squeezes the return spring 20 and moves upward along the limiting slide bar 16, and the ejector pin 19 is then ejected from the mold core 17, thereby ejecting the injection molded part in the mold core 17. This demoulding method is convenient and quick, and the injection molded part can be demoulded without disassembling the mold.

[0033] In actual use, when the injection mold is to be demoulded, firstly, hot-melt plastic raw material is injected into the mold core 17 through the injection port 14, and then coolant is input into the cooling tube 5 to accelerate the cooling of the injection molded part in the mold core 17.
