[0024] In this embodiment, the threaded rod 7 is electrically driven by the lifting motor 5, so that the connecting block 8 drives the upper mold 1 to lift inside the lifting groove 6, and the guide block 9 is conducive to guiding, ensuring the stability of the lifting of the connecting block 8, so that the upper mold 1 is connected to the lower mold 2, and the guide rod 4 is conducive to ensuring the stability of the lifting of the upper mold 1. A sealing strip is installed on the top of the lower mold 2, and then the feed port 3 facilitates the injection of the upper mold 1, which is conducive to the injection molding of the product. A spring damping rod 11 is installed on the inner side of the lower mold 2. When the connecting block 8 drives the upper mold 1 to descend, the upper mold 1 contacts and presses the pad 13 and the sealing fixing frame 16 downward, so that the pad 13 presses the spring damping rod 11 synchronously, and then the spring damping rod 11 is compressed. After the product is injection molded, the connecting block 8 drives the upper mold 1 to rise, and the spring damping rod 11 is released from the force compression, thereby driving the pad 13 to pop out. The pad 13 is arranged inside the lower mold 2, and the top of the pad 13 is installed with a side support column 15, and the side panel 14 is fitted on the side of the side support column 15. The sealing fixing frame 16 is clamped and limited to the side panel 14. The top of the sealing fixing frame 16 is provided with a sealing frame, which is beneficial to avoid leakage during injection molding. When the product is injection molded, only the sealing fixing frame 16 needs to be removed to make the side panel 14 fall off, which is beneficial to demoulding the product. The operation is simple and the installation and disassembly are convenient, which effectively reduces the demoulding waiting time and improves the production efficiency. At the same time, it reduces the wear and damage of the mold during the demoulding process and improves the quality of the product.

[0025] Example 2

[0026] like Figure 1-Figure 5 As shown, a bottom plate 10 is installed at the bottom of the lower mold 2, a connecting plate is installed on the side of the bottom plate 10, a water pump 18 is installed on the top of the connecting plate, a right-angle steel pipe 20 is connected to the side of the water pump 18, one end of the right-angle steel pipe 20 is connected to a spray rack 21, and a plurality of nozzles are distributed on the side of the spray rack 21, a fan 17 is arranged at the bottom of the lower mold 2, one end of the water pump 18 is connected to a connecting pipe 19, a support frame is installed at the bottom of the lower mold 2, and one end of the support frame is connected to the bottom of the fan 17.

[0027] In this embodiment, an external water pipe is connected to one end of the connecting pipe 19, and water is pumped by a water pump 18. The water reaches the spray rack 21 through a right-angle steel pipe 20 and is finally sprayed out from a nozzle to quickly cool the mold. At the same time, a fan 17 is installed at the bottom of the lower mold 2. The fan 17 cooperates with water cooling to efficiently cool the product after injection molding, effectively reducing the cooling waiting time, increasing the product molding speed, and further increasing the product demolding speed. A sealing baffle is provided at the bottom of the spring damping rod 11, and the sealing baffle is provided above the fan 17, so that no leakage will occur and the normal operation of the fan 17 will not be affected.

[0028] The working principle of this embodiment is as follows: when in use, first, a side support column 15 is installed on the top of the pad 13, and the side plate 14 is fitted on the side of the side support column 15. The sealing and fixing frame 16 clamps and limits the side plate 14, and the assembled one is put into the interior of the lower mold 2. Then, the threaded rod 7 is electrically driven by the lifting motor 5, so that the connecting block 8 drives the upper mold 1 to descend on the inner side of the lifting groove 6. The guide block 9 is conducive to guiding and ensures the stability of the lifting of the connecting block 8, so that the upper mold 1 is connected with the lower mold 2. When the connecting block 8 drives the upper mold 1 to descend, the pad 13 and the sealing and fixing frame 16 are contacted and pressed down by the upper mold 1, so that the pad 13 presses down the spring damping rod 11 synchronously. Then the spring damping rod 11 is compressed, and then the feed port 3 facilitates the injection of material into the upper mold 1. After the injection is completed, the external water pipe is connected to one end of the connecting pipe 19 at the same time, and the water source is pumped by the water pump 18, and the water source reaches the spray rack 21 through the right-angle steel pipe 20, and finally sprayed out from the nozzle to quickly cool the mold. At the same time, a fan 17 is installed at the bottom of the lower mold 2. The fan 17 cooperates with water cooling to cool the product after injection molding. After waiting for the product to cool and form, the connecting block 8 drives the upper mold 1 to rise, and the spring damping rod 11 is released from the compression, thereby driving the pad 13 to pop out, and the sealing fixing frame 16 is removed, so that the side plate 14 falls off, which is conducive to demolding the product.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
