The utility model provides a technical solution: an injection molding device for automobile parts, including a bottom plate 1, a plurality of vertical rods 2 are fixedly connected to the top surface of the bottom plate 1, the top ends of the vertical rods 2 are fixedly connected to the top plate 3, a cylinder 4 is fixedly installed on the top surface of the top plate 3, the output end of the piston rod of the cylinder 4 is fixedly connected to one end of the connecting rod 41, and the other end of the connecting rod 41 is fixedly installed with a lifting plate 5, a plurality of through holes 51 are provided on the top surface of the lifting plate 5, and the through holes 51 are slidably connected to the vertical rods 2, an upper mold 8 is fixedly installed on the bottom surface of the lifting plate 5, and sliding frames 9 are fixedly installed at both ends of the bottom surface of the lifting plate 5;

[0024] The lower mold 10 is fixedly installed on the top surface of the bottom plate 1, and a built-in groove 101 is provided in the lower mold 10. The built-in groove 101 is slidably connected to the ejection block 11. The ejection block 11 has a certain counterweight. During the downward movement of the sliding frame 9, the connecting frame 12 will be moved down to the bottom by the force of the counterweight of the ejection block 11. The two sides of the ejection block 11 are respectively fixed to the connecting frames 12, and the top of the connecting frame 12 is fixed to the limit plate 121. The bottom surface of the sliding frame 9 is provided with a second through-port 91, and the connecting frame 12 is slidably connected in the second through-port 91. The limit plate 121 is slidably connected to the sliding frame 9. After the injection molding is completed, the ejection block 11 can be driven to move up and eject as the upper mold 8 moves up to a suitable position.

[0025] Embodiment 2:

[0026] See also Figure 1-4 , which is the second embodiment of the utility model, is based on the previous embodiment, and sliding grooves 102 are respectively provided on both sides of the built-in groove 101, and the connecting frame 12 is slidably connected to the sliding grooves 102. The sliding grooves 102 can limit the moving range of the connecting frame 12.

[0027] Two ends of the top surface of the lifting plate 5 are respectively provided with a through opening 52 , and the limiting plate 121 is slidably connected to the through opening 52 . When the lifting plate 5 moves, the limiting plate 121 slides in the through opening 52 and the sliding frame 9 .

[0028] The lower mold 10 has slots 103 on both sides, and the sliding slots 102 and slots 103 are connected. When the lifting plate 5 and the upper mold 8 move downward, the sliding frame 9 moves downward and slides on the connecting frame 12. When the sliding frame 9 moves downward to a certain position, it slides in the slots 103 set on both sides of the lower mold 10 until the sliding frame 9 contacts the bottom of the connecting frame 12 and presses the connecting frame 12 to move to the bottom surface of the sliding slot 102, so that the ejector block 11 moves downward with the upper mold 8 into the lower mold 10, which is convenient for injection molding.

[0029] The top surface of the bottom plate 1 is fixed with one end of a plurality of springs 6, and the other end of the spring 6 is fixed with a connecting plate 7. The spring 6 is sleeved on the vertical rod 2, and can contact the connecting plate 7 during the downward movement of the lifting plate 5 to drive the connecting plate 7 to move downward and squeeze the spring 6, thereby playing a certain buffering role.

[0030] A second through hole 71 is provided on the top surface of the connecting plate 7 , and the second through hole 71 is slidably connected to the vertical rod 2 , thereby improving the stability of the movement of the connecting plate 7 .

When the utility model is actually used, after the parts are injection molded, the cylinder 4 is connected to an external power supply, and the lifting plate 5 and the upper mold 8 are driven to move upward by starting the cylinder 4. At the same time, the sliding frame 9 arranged on the bottom surface of the lifting plate 5 moves upward accordingly, and the sliding frame 9 slides on the connecting frame 12. When the sliding frame 9 moves up and contacts the limit plate 121, the limit plate 121 and the connecting frame 12 can be driven up by the upward movement of the sliding frame 9, so that the ejection block 11 moves up accordingly to eject the inner wall of the lower mold 10, so that the injection molded parts can be ejected from the inner wall of the lower mold 10 after the parts are injection molded, so that the staff can take out the injection molded parts, and the staff can demould and operate conveniently.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
