[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] Since the clamping ring 9 is against the outside of the clamping groove 8 of the circular clamping block 7, the movable plate 3 is moved by the operation of the hydraulic rod 6, and then the push rod 4 and the movable mold 1 are driven to slide relative to each other. The push rod 4 will squeeze the end cover for the first push demoulding of the end cover.
[0026] like Figures 1 to 6 As shown, the ends of the plurality of push rods 4 correspond to different bending and horizontal positions of the injection-molded end cover of the instrument panel.
[0027] It is used for pushing a plurality of push rods 4 to different positions of the injection molded end caps, so as to improve the success of demoulding.
[0028] like Figures 1 to 6As shown, a through hole 10 is provided at the end of the push rod 4, and the inside of the through hole 10 is slidably connected to the extrusion rod 5. A sliding hole 11 is provided at the bottom of the extrusion rod 5, and a positioning rod 12 is slidably installed inside the sliding hole 11. A first extrusion slope 13 is provided at one end of the positioning rod 12, and a return spring 14 is fixedly installed at the end of the positioning rod 12 away from the first extrusion slope 13. The end of the return spring 14 away from the positioning rod 12 is fixedly connected to the inner wall of the extrusion rod 5, and a second extrusion slope 15 is provided at a position corresponding to the first extrusion slope 13 inside the movable mold 1, and the second extrusion slope 15 is slidingly arranged in contact with the first extrusion slope 13.
[0029] When the push rod 4 extrude the end cap, the first extrusion slope 13 on the positioning rod 12 will squeeze the second extrusion slope 15, which will drive the positioning rod 12 to slide inside the sliding hole 11. At this time, the return spring 14 is in a compressed state. When the first extrusion slope 13 slides out of the second extrusion slope 15, the extrusion rod 5 slides inside the perforation 10 to push the end cap to be demoulded for the second time.
[0030] like Figures 1 to 6 As shown, the positioning rod 12 is vertically arranged at an angle close to one end of the first extrusion slope 13 .
[0031] It is used to stabilize the positioning rod 12 when it slides inside the through hole 10.
[0032] like Figures 1 to 6 As shown, a push spring 16 is fixedly installed at one end of the extrusion rod 5 close to the sliding hole 11 , and one end of the push spring 16 away from the extrusion rod 5 is fixedly connected to the inner wall of the push rod 4 .

[0037] When the device is in use, the movable mold 1 and the fixed mold 2 are combined to inject the end cover of the instrument panel, and then the movable mold 1 is moved, and the movable plate 3 is driven to move by the operation of the hydraulic rod 6, and then the push rod 4 is driven to slide relative to the movable mold 1, and the push rod 4 will squeeze the end cover for the first push demoulding of the end cover. In this process, the first extrusion slope 13 on the positioning rod 12 will squeeze the second extrusion slope 15, and will drive the positioning rod 12 to slide inside the sliding hole 11. At this time, the return spring 14 is in a compressed state, and the first extrusion slope 13 slides out of the second extrusion slope 15. When the mold is removed, the extrusion rod 5 is pushed to slide inside the perforation 10 by the action of the push spring 16, so as to demould the end cover for the second time. After the material is unloaded, the movable mold 1 and the fixed mold 2 are closed, and the fixed mold 2 extrude the extrusion rod 5, driving the first extrusion slope 13 on the positioning rod 12 to move to the second extrusion slope 15. The positioning rod 12 is pushed by the return spring 14, which drives the first extrusion slope 13 on the positioning rod 12 to move to the lowest end of the second extrusion slope 15. At this time, the push spring 16 is in a compressed state, so as to realize the next injection molding.
