[0033] Reference Figures 3 and 4 As shown, the outside of the slider 6 is slidably connected to the inside of the support plate 2, and the outside of the ejector plate 11 is slidably connected to the inside of the lower mold 14. The adjacent side of the multiple sliders 6 is fixedly connected with a connecting plate 7, and the top of the connecting plate 7 is fixedly connected with a connecting rod 8. The connecting rod 8 is to prevent the spring 9 from deforming. The outside of the connecting rod 8 is provided with a spring 9, which uses its own elastic potential energy to assist the ejector plate 11 to reset. One side of the spring 9 is fixedly connected to the top of the connecting plate 7, and the other side of the spring 9 is fixedly connected to the inside of the push cylinder 10. The top of the connecting rod 8 is fixedly connected to The push cylinder 10 is used to push the product after injection molding. The outside of the push cylinder 10 is slidably connected to the push plate 11. The push plate 11 is used to eject the product. A limiting groove 12 is provided inside the push plate 11. The limiting groove 12 is used to limit the limiting block 13. The internal sliding connection of the limiting groove 12 is used to limit the limiting block 13. The outside of the limiting block 13 is fixedly connected to the outside of the push cylinder 10. The top of the lower mold 14 is engaged with the bottom of the upper mold 18. The top of the two support plates 2 is fixedly connected to the lower mold 14, which can provide accurate cavity and support for injection molding.

[0034] Reference Figure 2As shown, the top of the support plate 1 2 is fixedly connected to the support plate 2 15, which ensures the integrity and stability of the mold structure. The top of the support plate 2 15 is fixedly connected to a power component for pushing the upper mold 18. The power component includes an air pump 2 16, which provides power support for related actions of the mold. The bottom of the air pump 2 16 is fixedly connected to the top of the support plate 2 15, and the driving end of the air pump 2 16 is fixedly connected to a push rod 2 17. The left and right sides of the upper mold 18 are fixedly connected with a slider 2 19. The upper mold 18 and the lower mold 14 cooperate closely to form a complete injection cavity, thereby ensuring the shape and dimensional accuracy of the injection molded product.

[0035] Reference Figures 5 and 6 As shown, the interior of the support plate 15 is provided with two slide grooves 20, and the interior of the lower mold 14 is provided with two injection ports 21, which can effectively control the flow rate of the injection liquid. The interior of the lower mold 14 is fixedly connected with two insulation cylinders 22. The material of the insulation cylinder 22 is ceramic fiber material, which effectively reduces heat loss and keeps the temperature of the injection liquid stable. The material of the insulation cylinder 23 is aluminum alloy. The interior of the insulation cylinder 1 22 is fixedly connected with the insulation cylinder 2 23, which further improves the temperature stability of the injection liquid. The interior of the insulation cylinder 2 23 is fixedly connected with a heating wire 24, which can quickly generate uniform heat and transfer the heat to the injection liquid to make it reach a suitable injection temperature. The interior of the heating wire 24 is provided with a delivery pipe 25, and the front side of the delivery pipe 25 is fixedly connected with a nozzle 26, so that the injection liquid is evenly injected into the mold cavity. The rear side of the two delivery pipes 25 is fixedly connected with a diversion pipe 27.

[0036] Working principle: First, start the air pump 16, so that the air pump 16 drives the push rod 17 to make the upper mold 18 cooperate with the slider 19 to close the upper mold 18 and the lower mold 14, and then inject the injection liquid into the space between the lower mold 14 and the upper mold 18 through the diverter pipe 27 and the nozzle 26;

[0037] After injection molding is completed, cylinder 3 is first activated, pushing push rod 4 forward. The movement of push rod 4 drives the connected slider 6 to slide in the chute 5, allowing slider 6 to move stably and accurately. The movement of slider 6 transmits force through connecting plate 7 and connecting rod 8, ultimately pushing ejector plate 11 forward. During this movement, ejector plate 11 ejects the completed product from lower mold 14. During this process, spring 9 acts as a buffer and assists in reset, ensuring a smooth ejection. The cooperation between limit groove 12 and limit block 13 limits the range of movement of ejector plate 11, preventing it from over-ejecting. This allows push cylinder 10 to first loosen the completed product and then lift it through ejector plate 11, thus ensuring the accuracy and safety of the ejection operation.

[0038] When the injection molding liquid is added, the mold carefully heats and insulates the injection molding liquid for the next stage. The injection port 21 is used to introduce the injection molding liquid into the mold. Before this, the injection molding liquid is heated by the heating wire 24 inside the insulation cylinder 1 22 and the insulation cylinder 2 23. The insulation cylinder 1 22 is made of ceramic fiber material, which has extremely low thermal conductivity and good heat resistance. It can effectively reduce heat loss and maintain the temperature of the injection molding liquid. At the same time, its surface has a certain roughness, which can increase the contact area with the injection molding liquid and improve heating efficiency. The insulation cylinder 2 23 is made of aluminum alloy material. This material is light and has excellent thermal conductivity. It can quickly transfer the heat generated by the heating wire 24 to the injection molding liquid, allowing the injection molding liquid to quickly reach the appropriate injection temperature. Moreover, the aluminum alloy material is easy to process and has relatively low cost. The heat generated by the heating wire 24 is evenly transferred to the injection molding liquid, allowing it to reach the appropriate injection temperature. At the same time, the delivery pipe 25 transports medium such as hot water or hot oil to the insulation cylinder, further enhancing the insulation effect. After being heated, the injection molding liquid is evenly distributed through the diverter pipe 27 and then accurately injected into the mold through the nozzle 26. This design ensures that the injection molding liquid maintains good fluidity and temperature stability when injected into the mold, thereby improving the quality and efficiency of injection molding.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
