A liquid inlet pipe 9 is fixedly connected to the inside of the lower mold 3 at one end of the liquid outlet pipe 11. An electric push rod 12 is fixedly connected to the inside of the lower mold base 4. A top rod 13 is fixedly connected to the top of the electric push rod 12. The top rod 13 penetrates through the lower mold 3 and the lower mold base 4. A limiting rod 8 is fixedly connected to the top of the lower mold base 4 outside the lower mold 3. An upper mold base 14 is movably installed on the periphery of the limiting rod 8. A pressing rod 1 is movably installed inside the upper mold base 14. A connecting plate 6 is fixedly connected to the top of the pressing rod 1. An upper mold 2 is fixedly connected to the bottom of the upper mold base 14.

[0024] The staff connects the device to an external push-pull actuator structure. By pushing the upper mold base 14 downward, the upper mold 2 and the lower mold 3 are engaged. Then, the injection molding workpiece raw material is poured into the device. By forming the raw material in the cavity formed by the upper mold 2 and the lower mold 3, after injection molding, by connecting an external coolant inlet and outlet structure to the liquid inlet pipe 9 and the liquid outlet pipe 11, the coolant circulates inside the lower mold 3 through the liquid inlet pipe 9 and the liquid outlet pipe 11. Both the liquid inlet pipe 9 and the liquid outlet pipe 11 are made of heat-dissipating copper material, which can quickly absorb the heat of the lower mold 3 and quickly complete heat exchange with the flowing coolant, quickly cool the workpiece, and make it quickly reach the temperature at which it can be demolded. By pushing the pressing rod 1 downward until it contacts the workpiece, and then pulling the upper mold base 14 upward, the workpiece is separated from the upper mold 2. By controlling the electric push rod 12 to push the top rod 13 upward, the workpiece is ejected from the lower mold 3 by the top rod 13, thus facilitating the staff to quickly perform the demolding operation.

[0025] Referring to Figure 1 , positioning members 5 are fixedly connected to both ends of the lower mold base 4. There are insertion holes inside the positioning members 5. The staff connects the positioning members 5 to an external structure, and then screws an external fixing bolt into the space between the positioning members 5 and the external structure and through the insertion holes, so as to fixedly install the device on the external structure.

[0026] Referring to Figure 1 , a fixed frame 7 is fixedly connected to the top of the upper mold base 14, and there are screw holes inside the fixed frame 7. By connecting an external pushing structure to the fixed frame 7, and then screwing an external fixing bolt into the space between the external pushing structure and the fixed frame 7 and into the screw holes inside, the external pushing structure can be fixedly connected to the upper mold base 14.

[0027] Reference Figure 1 On both sides inside the connecting plate 6, bolt holes 601 are provided, and there are four bolt holes 601. By connecting the external push-pull structure to the connecting plate 6 and screwing the external fixing bolts into the space between the connecting plate 6 and the external push-pull structure and passing through the bolt holes 601, the external push-pull structure can be fixed to the connecting plate 6.

[0028] Reference Figure 1 On one side of both the liquid inlet pipe 9 and the liquid outlet pipe 11, a flange 10 is fixedly connected, and threads are provided inside the flange 10. By fixing the external coolant introduction structure to the flange 10 and making it engage with the threads, the coolant introduction structure can be connected to the liquid inlet pipe 9 and the liquid outlet pipe 11.

[0029] The implementation principle of a mold facilitating demolding in the embodiment of this application is as follows: By pushing the upper mold base 14 down to fit with the lower mold 3, then pouring the raw material of the injection-molded workpiece into the device, so that the raw material forms a cavity between the upper mold 2 and the lower mold 3. By connecting the external coolant introduction and discharge structures to the liquid inlet pipe 9 and the liquid outlet pipe 11, the coolant circulates inside the lower mold 3 through the liquid inlet pipe 9 and the liquid outlet pipe 11, quickly cooling the workpiece to make it quickly reach the temperature at which it can be demolded. Then push the pressure rod 1 down to contact the workpiece, and pull the upper mold base 14 up to separate the workpiece from the upper mold 2. By controlling the electric push rod 12 to push the ejector rod 13 up, the workpiece is ejected from the lower mold 3 by the ejector rod 13.
