The rotation of the threaded rod 10 cooperates with the transmission assembly to drive the top block 11 to move, thereby pressing the upper fixed plate 5 downward and pushing the lower fixed plate 6 upward, thereby realizing the fitting and pressing of the upper mold 1 and the lower mold 2. Compared with the existing device, it avoids the need for an additional pressing device to press the two molds together before the injection molding operation can be performed, which is a more cumbersome operation and improves the production efficiency.

[0022] Reference Figure 3-5 A plurality of limit blocks 12 are fixedly connected in pairs inside the cavity 9, and the top block 11 is slidably arranged between two limit blocks 12 in the same group, and both sides of the top block 11 are in contact with the limit blocks 12, thereby improving the stability and smoothness of the sliding of the top block 11.

[0023] The transmission assembly includes a plurality of sliders 13 threadedly sleeved on the threaded rod 10, and the sliders 13 correspond to the top blocks 11 one by one, and the opposite sides of the sliders 13 and the top blocks 11 are inclined, and one end of the threaded rod 10 extends to the outside of the baffle 8 and is fixedly connected with a handle 14. The threaded rod 10 is rotated by the handle 14, and the sliders 13 drive the top blocks 11 to move through the inclined surfaces, thereby realizing the fixation of the top blocks 11 to the upper fixed plate 5 and the lower fixed plate 6.

[0024] Reference Figure 3-5 There is a gap between the limit block 12 and the slider 13, and the relative sides of the limit block 12 and the slider 13 are parallel to each other, so as to limit the slider 13 and prevent the slider 13 from being separated from the top block 11.

[0025] The cavity 9 is provided with sliding grooves 15 on both sides of the top block 11, and a sliding plate 16 is slidably connected in the sliding groove 15, and the sliding plate 16 is fixedly connected to the side of the top block 11, and a spring 17 is fixedly connected between one side of the sliding plate 16 and the side wall of the sliding groove 15, and the spring 17 is used to realize automatic retraction of the top block 11 to avoid interference with the top block 11 when the plug plate 3 is inserted or removed.

[0026] Reference Figure 3 One end of the threaded rod 10 away from the handle 14 is fixedly connected to an auxiliary block 18 for limiting the slider 13. The limitation of the auxiliary block 18 prevents the slider 13 from being separated from the top block 11.

[0027] Working principle:

[0028] When the injection mold for automobile lamps is in use, the fixing holes of the upper mold 1 are aligned and the fixing rod 4 is inserted. After the upper mold 1 and the lower mold 2 are fitted together, the two plug plates 3 are respectively inserted into the through holes 7 on both sides. At this time, the handle 14 is rotated to drive the threaded rod 10 to rotate, thereby driving the slider 13 to move. The slider 13 then drives the top block 11 to slide vertically and fit the inner wall of the through hole 7, and the upper fixing plate 5 is pressed downward and the lower fixing plate 6 is pushed upward, so that the upper mold 1 and the lower mold 2 are pressed and fixed, and the injection molding operation can be performed. After the accommodation is completed, the handle 14 is rotated in the opposite direction to drive the threaded rod 10 to rotate. At this time, the spring 17 moves the top block 11 into the cavity 9, so that the plug plate 3 can be taken out, and the lower mold 2 can be separated from the lower mold 2. The above is the entire use process of the injection mold for automobile lamps.

[0029] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and utility model concept of the present application, which should be covered by the protection scope of the present application.
