[0030] See also Figure 1-5 A guide column for a product mold includes a guide column body 1, an upper and lower molding mechanism, a lubricating oil one-way sealing mechanism and a reset auxiliary mechanism. The lubricating oil one-way sealing mechanism includes an oil lubricating pipe 2, a sealing plate 3, a movable plate 4, a convex-concave block 5 and a convex-concave groove 6. The sealing plate 3 is fixedly installed at one end of the oil lubricating pipe 2, the convex-concave block 5 is arranged on the outer wall of the movable plate 4, and the convex-concave groove 6 is arranged on the inner wall of the sealing plate 3. The convex-concave block 5 and the convex-concave groove 6 can be movably matched to enable the sealing plate 3 and the movable plate 4 to be opened, closed and sealed. The reset auxiliary mechanism includes a movable plate 4, ... Rod 7, column hole 8, reset spring 9, inner frame 10 and adjustment ring 11, the movable rod 7 is installed on the inner side of the movable plate 4, the column hole 8 is set through the movable rod 7 and the central position of the movable plate 4, the inner frame 10 is fixedly mounted on the inner wall of the lubricating tube 2, one end of the reset spring 9 is connected to the inner frame 10, and the other end of the reset spring 9 extends into the interior of the column hole 8, multiple groups of adjustment rings 11 are set up and down on the reset spring 9, the inner diameter of the adjustment ring 11 decreases from top to bottom, and the adjustment ring 11 is movably set in the column hole 8.

[0031] In this embodiment, the external oil filling device presses the movable plate 4 to inject the lubricating oil into the oil lubricating tube 2. The oil lubricating tube 2 is filled with lubricating oil. When the guide column body 1 moves relatively, especially during the up and down movement of the molding mechanism, the lubricating oil flows into the space between the movable plate 4 and the sealing plate 3 through the oil groove 19. The convex and concave blocks 5 on the outer wall of the movable plate 4 cooperate with the convex and concave grooves 6 on the inner wall of the sealing plate 3 to achieve opening and closing and sealing. When the injection is stopped, the convex and concave blocks 5 cooperate with the convex and concave grooves 6 to seal and prevent the lubricating oil from flowing back, thereby ensuring the unidirectional flow of the lubricating oil, thereby effectively lubricating the contact surface between the guide column body 1 and the guide sleeve 12. When the reset auxiliary mechanism needs to be operated, during the mold opening and resetting stage of the upper and lower molding mechanisms, the reset auxiliary mechanism helps the movable plate 4 and related components of the lubricating oil one-way sealing mechanism to return to the initial position through the elastic force of the reset spring 9, ensuring that the lubricating oil one-way sealing mechanism can be effectively reset after each molding and prepare for the next lubrication process. By replacing external long rods of different lengths and thicknesses and extending them into the column hole 8 and connecting them with different adjustment rings 11, the elastic force of the reset spring 9 can be flexibly adjusted to adapt to the requirements of different molds, thereby ensuring the effectiveness and reliability of the reset mechanism.

[0032] The upper and lower forming mechanisms include a guide sleeve 12, a pressure plate 13, a base plate 14, an upper mold 15 and a lower mold 16. Four groups of guide column bodies 1 are installed at the four sides of the base plate 14. The guide sleeve 12 is fixedly arranged at the four sides of the pressure plate 13. The guide sleeve 12 is movably sleeved on the guide column body 1. The lower mold 16 is installed on the top end surface of the base plate 14. The upper mold 15 is connected to the bottom of the pressure plate 13, and the upper mold 15 and the lower mold 16 are arranged for relative movement.

[0033] In this embodiment, at the beginning of the molding process, the pressing plate 13 is moved downward by an external driving force such as hydraulic or mechanical drive, and the guide sleeve 12 slides along the guide column body 1, ensuring the stable and vertical downward movement of the pressing plate 13. The upper mold 15 moves downward with the pressing plate 13 and gradually approaches the lower mold 16. When the pressing plate 13 moves down to the set position, the upper mold 15 and the lower mold 16 are completely docked to form a closed mold space to complete the molding process of the product. After the molding is completed, the pressing plate 13 moves upward in the opposite direction, and the guide sleeve 12 slides along the guide column body 1 to the initial position. The upper mold 15 and the lower mold 16 are separated, completing a molding cycle.

[0035] More specifically, the design of the inner fixing plate 18 and the movable column 20 not only provides a sealing function for the lubrication system to prevent leakage of lubricating oil, but also increases the stability of the overall structure. The setting of the connecting column 21 and the connecting bolt 22 makes the connection between the upper mold 15 and the pressure plate 13 more secure. At the same time, the application of the locking sleeve 23 and the base bolt 24 ensures the stability of the guide column body 1 and the bottom plate 14 and the reliability of the mold as a whole. By replacing the connection between the external long rod of different length and thickness and the adjustment ring 11, the elastic strength of the reset spring 9 can be flexibly adjusted to meet different molding force and speed requirements.

[0036] In summary, when the overall equipment is in use or running: when the operation of the lubricating oil one-way sealing mechanism is required, the external oil filling device presses the movable plate 4 to inject the lubricating oil into the oil lubricating tube 2, and the inside of the oil lubricating tube 2 is filled with lubricating oil. When the guide column body 1 moves relatively, especially during the up and down movement of the molding mechanism, the lubricating oil flows into the space between the movable plate 4 and the sealing plate 3 through the oil groove 19, and the convex and concave blocks 5 on the outer wall of the movable plate 4 cooperate with the convex and concave grooves 6 on the inner wall of the sealing plate 3 to achieve opening and closing and sealing. When the injection is stopped, the convex and concave blocks 5 cooperate with the convex and concave grooves 6 to seal and prevent the lubricating oil from flowing back, thereby ensuring the one-way flow of the lubricating oil, thereby effectively lubricating the contact surface between the guide column body 1 and the guide sleeve 12.

[0037] When the reset auxiliary mechanism needs to be operated, during the mold opening and reset stage of the upper and lower molding mechanisms, the reset auxiliary mechanism uses the elastic force of the reset spring 9 to help the movable plate 4 and related components of the lubricating oil one-way sealing mechanism return to the initial position, ensuring that the lubricating oil one-way sealing mechanism can be effectively reset after each molding and prepare for the next lubrication process. By replacing external long rods of different lengths and thicknesses that are inserted into the column hole 8 and connected to different adjustment rings 11, the elastic force of the reset spring 9 can be flexibly adjusted to adapt to different lubrication requirements, thereby ensuring the effectiveness and reliability of the reset mechanism.

[0038] When the upper and lower molding mechanisms need to be operated, at the beginning of the molding process, the pressing plate 13 moves downward by an external driving force such as hydraulic or mechanical drive, and the guide sleeve 12 slides along the guide column body 1, ensuring the smooth and vertical downward movement of the pressing plate 13. The upper mold 15 moves downward with the pressing plate 13 and gradually approaches the lower mold 16. When the pressing plate 13 moves down to the set position, the upper mold 15 and the lower mold 16 are completely docked to form a closed mold space to complete the molding process of the product. After the molding is completed, the pressing plate 13 moves upward in the opposite direction, and the guide sleeve 12 slides along the guide column body 1 to the initial position. The upper mold 15 and the lower mold 16 are separated, completing a molding cycle.
