[0021] like Figure 1 As shown, the utility model provides a technical solution: an injection mold for a car charging pile shell, comprising a base 10, a workbench 11 is fixedly installed on the upper end surface of the base 10, rectangular openings 12 are opened on both sides of the workbench 11, a lower mold frame 13 is arranged between the two rectangular openings 12, the lower mold frame 13 is fixed to the upper end surface of the base 10, and an adaptive upper mold frame 14 is arranged above the lower mold frame 13, and a lifting component for moving the upper mold frame 14 is arranged on the inner side of the rectangular opening 12, and a lifting component for lifting the mold is connected to the lifting component. During specific use, the upper mold frame 14 is driven by the provided lifting component to lift up and down, so as to open and close the mold. This design not only improves production efficiency, but also reduces the labor intensity of operators, and the lifting component drives the lifting component to lift up and down synchronously, so that the injection molded parts after injection molding can be ejected during the mold opening process, which greatly simplifies the part removal process and improves the degree of production automation.

[0022] As an implementation method in this embodiment, Figure 1 and Figure 2As shown, the lifting assembly includes a limiting slide rail 20 fixed on the inner wall of the rectangular opening 12, and a sliding plate 21 is slidably connected to the limiting slide rail 20. A connecting rod 22 is fixedly installed on the side wall of the sliding plate 21 close to the upper mold frame 14, and the other end of the connecting rod 22 is fixedly installed on the outer wall of the upper mold frame 14. A rack 23 is fixedly installed on the side wall of the sliding plate 21 away from the limiting slide rail 20, and a driving assembly is arranged on one side of the rack 23. During specific use, the moving range and trajectory of the sliding plate 21 are limited by the setting of the limiting slide rail 20, so as to drive the sliding plate 21 to slide up and down stably, and the sliding plate 21 drives the connecting rod 22 to move up and down synchronously, so that the upper mold frame 14 is lifted and lowered synchronously, and the setting of the rack 23 is used in conjunction with the driving assembly, so as to drive the sliding plate 21 to move synchronously through the rack 23.

[0023] As an implementation method in this embodiment, Figure 1 As shown, the driving assembly includes a mounting plate 24 fixedly mounted on the upper end surface of the workbench 11, a driving rod 25 is horizontally penetrated through the mounting plate 24, the driving rod 25 is rotatably connected to the mounting plate 24, a gear 26 is fixedly sleeved on one end of the driving rod 25, the gear 26 is meshed with the rack 23 for transmission, a driving motor 27 is fixedly mounted on the other end of the driving rod 25, a storage plate 28 is fixedly mounted on the side wall of the mounting plate 24, and the driving motor 27 is fixedly mounted on the storage plate 28. During specific use, the gear 26 on the driving rod 25 is driven to rotate by the set driving motor 27, so that the gear 26 drives the rack 23 to transmit up and down, and the rack 23 can drive the sliding plate 21 to move synchronously, thereby driving the upper mold frame 14 to move synchronously.

[0024] As an implementation method in this embodiment, Figure 3 As shown, the ejection assembly includes a transverse plate 30, both ends of which are fixedly connected to the corresponding side walls of the sliding plate 21, and a plurality of ejector rods 31 are fixedly connected in an array on the upper end surface of the transverse plate 30, and the top ends of the ejector rods 31 vertically upwardly pass through the top wall of the workbench 11 and the bottom wall of the lower mold frame 13 in sequence. During specific use, when the sliding plate 21 moves up and down, the transverse plate 30 moves synchronously, so that the transverse plate 30 drives the ejector rods 31 to move up and down, so that the lifting operation of the ejector rods 31 can cooperate with the mold opening at the same time, thereby improving the production efficiency to a certain extent.

[0025] As an implementation method in this embodiment, Figure 2 , Figure 4 and Figure 5As shown, a plurality of through holes 101 adapted to the ejector rod 31 are arranged in an array on the base 10, and a plurality of through holes 131 adapted to the ejector rod 31 are arranged in an array on the inner bottom wall of the lower mold frame 13. The ejector rod 31 passes through the top wall of the workbench 11 and the bottom wall of the lower mold frame 13 through the through holes 101 and the through holes 131, so that the ejector rod 31 can shuttle up and down in the base 10 and the lower mold frame 13.

[0026] As an implementation method in this embodiment, Figure 1 and Figure 3 As shown, a material guide tube 15 is provided at the top of the upper mold frame 14. The bottom end of the material guide tube 15 passes through the top wall of the upper mold frame 14 and the port is flush with the inner top wall of the upper mold frame 14. The material guide tube 15 is used to transport the injection material into the mold to avoid leakage or overflow of the material during the transportation process.

[0027] As an implementation method in this embodiment, Figure 4 As shown, universal wheels 16 are fixedly installed at the four corners of the lower end surface of the base 10. The universal wheels 16 are a lockable structure. The setting of the universal wheels 16 can make the entire device movable and placed, making it more convenient to use.

[0028] Working principle: When in use, the drive motor 27 is used to drive the gear 26 on the drive rod 25 to rotate, so that the gear 26 drives the rack 23 to transmit up and down, and the rack 23 can drive the sliding plate 21 to move synchronously. The moving range and trajectory of the sliding plate 21 are limited by the set limit slide rail 20, driving the sliding plate 21 to slide up and down stably, and the sliding plate 21 drives the connecting rod 22 to move up and down synchronously, so that the upper mold frame 14 is lifted and lowered synchronously. When the sliding plate 21 moves up and down, the cross plate 30 moves synchronously, so that the cross plate 30 drives the ejector rod 31 to move up and down, so that the lifting operation of the ejector rod 31 can be carried out simultaneously with the mold opening.

[0029] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
