[0033] An embodiment of the present application discloses an injection mold for a charging port connector.
[0034] Reference Figure 1 and Figure 2 An injection mold for a charging port connector includes a sub-mold 7 and a main mold 6. The sub-mold 7 and the main mold 6 are provided with cavities for forming an insulating seat. There are two cavities and they are symmetrically arranged on the main mold 6 and the sub-mold 7. The main mold 6 is provided with a plurality of injection tubes 8 connected with the cavities. Raw materials are injected into the cavities through the injection tubes 8. The raw materials are wrapped on the copper tube and the insulating seat is formed on the copper tube by insert injection molding.
[0035] Reference Figure 1 , Figure 2 and Figure 3 The main mold 6 includes a fixed mold 9 and a sliding mold. The sliding mold is located on the extension line of the line connecting the two cavities and is symmetrically arranged on both sides of the vertical line connecting the two cavities. The sliding mold is slidably arranged on the main mold 6. The sliding mold slides along the direction of the line connecting the two cavities. The sliding mold includes a driving mold 10 and an abutting mold 11. The abutting mold 11 is located between the driving mold 10 and the fixed mold 9. The abutting mold 11 is detachably connected to the driving mold 10. A positioning core 12 is fixed on the abutting mold 11. The positioning core 12 is inserted into the copper tube. The positioning core 12 is stepped. When the positioning core 12 is inserted into the copper tube, the end of the copper tube abuts on the stepped surface of the positioning core 12. A stopper 13 is fixed on the abutting mold 11, which is used to close the opening on the side of the main mold 6 for the abutting mold 11 to slide, so that the side opening of the cavity is closed to form an insulating seat.
[0036] Reference Figure 2 , Figure 3 and Figure 4 The injection mold also includes a driving device for driving the sliding mold to move toward the fixed mold 9 and forming the cavity. The driving device includes two driving rods 14. The two driving rods 14 are inclined and symmetrically arranged on both sides of the vertical line connecting the two cavities. A driving hole 15 is opened on the driving mold 10. The driving hole 15 is inclined. The driving rod 14 is inserted into the corresponding driving hole 15. The driving device also includes a driving source for moving the driving rod 14 up and down. The driving source is preferably a cylinder or an oil cylinder. When the driving source drives the driving rod 14 to move, it drives the driving mold 10 and the abutting mold 11 connected to the driving mold 10 to move in a direction close to or away from the fixed mold 9.
[0037] Reference Figure 3 , Figure 4 and Figure 5 The driving mold 10 is provided with a clamping groove 16, and a clamping block 17 is fixed on the abutting mold 11. The clamping block 17 is clamped in the clamping groove 16, and the end of the clamping block 17 abuts against the bottom wall of the clamping groove 16. A positioning assembly is provided in the clamping groove 16 to prevent the clamping block 17 from being separated from the clamping groove 16. Positioning grooves 18 are provided on the inner walls on both sides of the opposite sides of the clamping groove 16. The positioning assembly includes a positioning rod 19 slidably arranged in the positioning groove 18. A positioning hole 21 is provided on the side wall of the clamping block 17, and the positioning hole 21 corresponds to the positioning rod 19. A positioning spring 20 is fixed in the positioning groove 18, and one end of the positioning spring 20 is fixed in the positioning groove 18, and the other end of the positioning spring 20 is fixed at the end of the positioning rod 19. The positioning spring 20 pushes the positioning rod 19 to be inserted into the positioning hole 21, thereby realizing the connection between the driving mold 10 and the abutting mold 11.
[0038] Reference Figure 4 and Figure 5The clamping block 17 and the positioning rod 19 are provided with mutually parallel guide surfaces 22. When the driving mold 10 moves toward the abutting mold 11, the positioning rod 19 is pushed to move toward the positioning groove 18 under the action of the guide surface 22. When the positioning rod 19 moves to align with the positioning hole 21, the positioning spring 20 pushes the end of the positioning rod 19 to clamp into the positioning hole 21. After the insulating seat is cooled and finalized, the driving mold 10 drives the abutting mold 11 to move away from the fixed mold 9. Under the action of the positioning rod 19, the abutting mold 11 is driven to move away from the fixed mold 9, thereby facilitating the separation of the positioning core 12 from the copper tube, and then facilitating the later removal of the product.

The positioning core 12 is inserted into the corresponding mounting groove 23, and the end of the positioning core 12 abuts on the stepped surface of the mounting groove 23. A mounting hole 24 is opened on the side wall of the abutting mold 11. The mounting hole 24 passes through the positioning core 12 horizontally, and a mounting rod 25 connecting the two positioning cores 12 is inserted in the mounting hole 24. The setting of the mounting rod 25 is used to fix the positioning core 12 on the abutting mold 11, and at the same time facilitate the disassembly of the positioning core 12.
[0040] Reference Figure 4 and Figure 5 The positioning core 12 is an internal hollow cylindrical structure, and a through groove 26 penetrating the abutment mold 11 and the clamping block 17 is opened on the abutment mold 11 along the axial direction of the positioning core 12. The through groove 26 is provided to facilitate cooling and shaping during the molding process of the insulating seat.
[0041] Reference Figure 2 and Figure 5 A track groove 27 is provided on the side wall of the auxiliary mold 7, and a track block 28 is fixed on the abutting mold 11. The track block 28 is slidably set in the track groove 27. The setting of the track block 28 and the track groove 27 facilitates the overall positioning of the abutting mold 11, the main mold 6 and the auxiliary mold 7, thereby ensuring the stability of the overall structure.
[0042] The principle of the embodiment of the present application is: the copper tube of the conductive core tube is installed on the abutment mold 11, the positioning core 12 is inserted into the copper tube, and the end of the copper tube abuts on the stepped surface of the positioning core 12 to realize the installation and positioning of the copper tube on the mold. The staff can place it manually or use a robot to drive it to make the driving rod 14 slide relative to the driving hole 15, so that the driving mold 10 drives the abutment mold 11 to move toward the fixed mold 9, and works together with the sub-mold 7 to form a cavity for molding the insulating seat in the mold, and an insulating seat is formed on the surface of the copper tube by injection molding into the cavity. After cooling, it acts on the sliding mold, so that the sliding mold drives the positioning core 12 to move toward the outside of the main mold 6, which is convenient for product removal.
