[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0021] like Figures 1 to 5 As shown, a molding die for molding a decorative panel of an automobile instrument panel comprises a bottom plate 3 and a top plate 6, a lower mold 1 is fixedly connected to the middle of the upper end surface of the bottom plate 3, an upper mold 2 is fixedly connected to the middle of the lower end surface of the top plate 6, and lifting components for assisting demoulding are arranged on both sides of the upper mold 2 and the lower mold 1. The molding die is provided with a lifting component for assisting demoulding, and the upper mold 2 moves upward to drive the fixed cylinder to move upward, and the rotating rod 10 contacts the conical surface of the lower end of the connecting cylinder 11. Since the elastic force of the reset spring 12 on the ejector rod 14 is much smaller than the elastic force of the telescopic spring 9, the rotating rod 10 moves upward through the connecting cylinder 11. The connecting tube 11 drives the push rod 14 to move upward, so that the automobile dashboard trim panel inside the molding cavity is separated from the molding cavity. When the push rod 14 moves to the sliding position limit, the rotating rod 10 rotates and disengages from the connecting tube 11. The push rod 14 moves downward through the action of the reset spring 12, and the lifting component is linked with the lifting and lowering movement of the upper mold 2 to complete the auxiliary demolding work. Through the lifting component, the molding mold does not need manual assistance to unload during the production process of the automobile dashboard trim panel, which greatly improves the working efficiency of the molding mold and improves the production safety of workers.

[0022] Further, such as Figure 1As shown, guide rods 4 are fixedly connected at the four corners of the upper end surface of the bottom plate 3, and the upper ends of multiple guide rods 4 are slidably connected to the top plate 6. An injection tube 5 is fixedly connected to the middle of one side end surface of the upper mold 2. The molding mold limits the lifting and lowering movement of the upper mold 2 by the set guide rods 4, improves the movement stability of the upper mold 2, and completes the injection of the injection solution through the injection tube 5.

[0023] Further, such as Figures 2 to 5 As shown, the lifting assembly includes a fixed sleeve 7 fixedly connected to the middle part of one side of the lower end surface of the top plate 6, an open groove 8 is provided at the inner lower end of the fixed sleeve 7, a rotating rod 10 is rotatably connected inside the open groove 8, the rotating rod 10 is L-shaped and has rounded corners at the corners of one side of the lower end of the rotating rod 10, a telescopic spring 9 is fixedly connected to the middle part of one side of the inner wall of the open groove 8, one end of the telescopic spring 9 is fixedly connected to the middle part of the rotating rod 10, and the lifting assembly also includes a push rod 14 arranged on both sides of the molding cavity of the lower mold 1, the push rod 14 is slidably connected to the lower mold 1, and one side of the inner part of the lower mold 1 is fixedly connected to the upper end of the push rod 14. A return spring 12 is connected, and the lower end of the return spring 12 is fixedly connected to the push rod 14. The inner upper end of the lower mold 1 is located on one side of the return spring 12 and is fixedly connected to a retractable sealing gasket 13. The upper end of the retractable sealing gasket 13 is fixedly connected to the lower mold 1. One end of the push rod 14 passes through the lower mold 1 and is fixedly connected to a connecting tube 11. The upper and lower ends of the connecting tube 11 are both conical in design. When the upper mold 2 moves downward through the top plate 6, the fixed sleeve 7 fixedly connected to the top plate 6 moves downward synchronously. The upper and lower ends of the fixed sleeve 7 are rotatably connected to a rotating rod 10. The rotating rod 10 is L-shaped in design. During the descent process, first The upper and lower ends of the connecting tube 11 are both conical in design, so the rotating rod 10 will rotate after contacting the connecting tube 11. When the upper mold 2 moves to the working position, the rotating rod 10 is not in contact with the connecting tube 11. The rotating rod 10 is reset by the action of the telescopic spring 9 at the rear end. At this time, the molding mold injects the solution into the molding cavity through the injection pipe 5. The retractable sealing gasket 13 is set to prevent the solution from leaking. After completing the manufacturing process of the automobile instrument panel trim, the upper mold 2 moves upward to drive the fixed tube to move upward, and the rotating rod 10 and the lower end conical surface of the connecting tube 11 are connected. Contact, because the elastic force of the return spring 12 on the push rod 14 is much smaller than the elastic force of the telescopic spring 9, the rotating rod 10 drives the push rod 14 to move upward through the connecting tube 11 while moving upward, so that the automobile instrument panel trim inside the molding cavity is separated from the molding cavity. When the push rod 14 moves to the sliding position limit, the rotating rod 10 rotates and disengages from the connecting tube 11, and the push rod 14 moves downward by the action of the return spring 12. Through this structural design, during the production process of the automobile instrument panel trim, no manual assistance is required for unloading, which greatly improves the working efficiency of the molding mold.

[0024] Working principle: when the upper mold 2 moves downward through the top plate 6, the fixed sleeve 7 fixedly connected to the top plate 6 moves downward synchronously, and the upper and lower ends of the fixed sleeve 7 are rotatably connected with the rotating rod 10. The rotating rod 10 is L-shaped. During the descent, it first contacts the connecting tube 11. Since the upper and lower ends of the connecting tube 11 are both conical, the rotating rod 10 will rotate after contacting the connecting tube 11. When the upper mold 2 moves to the working position, the rotating rod 10 does not contact the connecting tube 11. The rotating rod 10 is reset by the action of the telescopic spring 9 at the rear end. At this time, the molding mold injects the solution into the molding cavity through the injection pipe 5. The retractable sealing pad 13 is set to prevent the solution from leaking, thus completing the molding of the automobile instrument panel. After the manufacturing process, the upper mold 2 moves upward, driving the fixed tube to move upward, and the rotating rod 10 contacts the conical surface of the lower end of the connecting tube 11. Since the elastic force of the reset spring 12 on the push rod 14 is much smaller than the elastic force of the telescopic spring 9, the rotating rod 10 drives the push rod 14 to move upward through the connecting tube 11 while moving upward, so that the automobile instrument panel trim inside the molding cavity is separated from the molding cavity. When the push rod 14 moves to the sliding position limit, the rotating rod 10 rotates and disengages from the connecting tube 11, and the push rod 14 moves downward by the action of the reset spring 12. Through this structural design, no manual assistance is required for unloading during the production process of the automobile instrument panel trim, which greatly improves the working efficiency of the molding mold.
