The top of the frame 501 is fixedly connected to the outer wall of the upper mold 4, so that the frame 501 is driven to move vertically along the inner wall of the bracket 1 during the vertical movement of the upper mold 4. The bottom inner wall of the frame 501 is slidably connected with a wedge block 503 to maintain the stability of the wedge block 503 during lateral movement. The outer wall of the wedge block 503 is fixedly connected to one end of a spring 504, and the other end of the spring 504 is fixedly connected to the inner wall of the frame 501, and the wedge block 503 is driven by the force of the spring 504 to move outward to maintain the clamping and fixing effect with the limit frame 502. The outer wall of the frame 501 is inserted into the limit frame 502, and the outer wall of the wedge block 503 is clamped with the inner wall of the limit frame 502, so that the frame 501 is connected and fixed to the sliding rail 601.

[0031] Reference Figure 3-Figure 4The lower mold 2 is provided with an adjustable demoulding mechanism 6, which includes a sliding track 601, the inner wall of the sliding track 601 is slidably connected with an ejector rod 602, and the ejector rod 602 is kept to move laterally along the inner wall of the sliding track 601, and the outer wall of the ejector rod 602 is movably connected with the inner wall of the lower mold 2 to maintain the airtightness of the lower mold 2 and the ejector rod 602 during the movement, and the outer wall of the ejector rod 602 is hinged with a connecting rod 603, and the outer wall of the connecting rod 603 is hinged with a sliding plate 604, and the bottom of the sliding plate 604 is slidably connected with the inner wall of the shell 606, so that the sliding plate 60 4 moves laterally along the inner wall of the housing 606, and during the lateral movement of the sliding plate 604, the positions of the two groups of ejector rods 602 are changed by the connecting rod 603. The inner wall of the housing 606 is rotatably connected with the threaded rod 605, and the outer wall of the threaded rod 605 is threadedly connected with the bottom of the sliding plate 604, so that the housing 606 provides a support effect for the threaded rod 605, and the sliding plate 604 is driven to move by rotating the threaded rod 605.

[0032] Working principle: By starting the hydraulic rod 3 to drive the upper mold 4 to move downward, the upper mold 4 is fitted with the lower mold 2, and the injection tube is controlled to transfer the injection liquid to the inner walls of the upper mold 4 and the lower mold 2 for storage, and the liquid is naturally formed by waiting, so as to obtain the finished car roof light box.

[0033] When the finished car ceiling light box placed in the inner wall of the lower mold 2 needs to be taken out after natural molding, the upper mold 4 is first driven to reset upward by starting the hydraulic rod 3 to achieve the purpose of opening, and the frame 501 is driven to move simultaneously during the vertical movement of the upper mold 4, so that the frame 501 drives the sliding track 601 to move vertically during the vertical movement, and the sliding track 601 drives the two groups of ejector rods 602 set on the top to move upward along the inner wall of the lower mold 2, so that the bottom of the finished car ceiling light box is squeezed upward by the two groups of ejector rods 602, so that the finished car ceiling light box is pushed out, and the purpose of rapid demolding is achieved.

[0034] At the same time, considering that when making car ceiling light boxes of different sizes, the sizes of molds required are also different, it is necessary to change the lateral position of the ejector rod 602. By rotating the threaded rod 605, the sliding plate 604 is driven to move laterally along the inner wall of the shell 606 during the rotation of the threaded rod 605, and the two sets of ejector rods 602 are driven to move along the inner wall of the sliding track 601 in cooperation with the connecting rod 603, thereby adapting to the use of lower molds 2 of different sizes to improve the adaptability of the device.
