[0020] The beneficial effects of the present invention are:

[0021] 1. This mold for the plastic sunroof of a car can control the lifting of the upper mold through the lifting module, which is convenient for mold opening and closing operations. When the upper mold is controlled to rise by the lifting module for mold opening operation, the lifting module can drive the driven gear on the groove wheel driving mechanism to rotate through the linkage gear on it. When the driven gear rotates, the driving cam can be driven to rotate through the driving rod. When the driving cam rotates, the moving plate can be driven to move to one side through the toggle column. During the movement of the moving plate, the lower mold can be driven to move to one side. When the lower mold moves to the linkage block, the extrusion slope on the linkage block can be used to extrude the demoulding mechanism upward. The molded plastic sunroof of the car in the lower mold can be quickly ejected through the demoulding mechanism, which is convenient for demoulding operation and saves time and effort.

[0022] 2. This type of mold for the plastic sunroof of a car, when the plastic mold has been used for a long time and some plastic debris remains in the lower mold cavity and needs to be cleaned, the lifting module continues to be controlled to rise, and the lifting module that continues to rise can continue to drive the lower mold to move to one side through the grooved wheel driving mechanism. When the gear flipping part on the mold flipping mechanism moves to the notch on the linkage flipping table, the gear flipping part can be driven to rotate 180 degrees through the linkage column. When the gear flipping part rotates, the lower mold can be flipped by rotating the shaft rod, and some plastic debris remaining in the lower mold cavity can be poured downwards, and the interior of the lower mold can be quickly cleaned.

[0023] 3. This type of mold for the sunroof plastic parts of automobiles, when the mold flipping mechanism drives the lower mold to flip, one side of the lower mold will contact the trigger mechanism, which can be linked to open the trigger mechanism. After the linkage is opened, the trigger mechanism will automatically control the mold flushing mechanism to open. The mold flushing mechanism can quickly flush the inside of the cavity of the lower mold, and some plastic debris remaining in the cavity of the lower mold can be quickly flushed away, which can effectively avoid the appearance quality and structural strength of the plastic molded sunroof plastic parts being affected. After cleaning, the upper mold is controlled to descend through the lifting module. At this time, the lifting module can be linked to drive the groove wheel driving mechanism to move in the opposite direction. When the groove wheel driving mechanism drives the lower mold to move in the opposite direction to complete the reset, the upper mold will also complete the mold closing at the same time, which is convenient to operate.

[0024] 4. This mold for the plastic sunroof of a car has rollers arranged on the limit plate on the gear flip part. The rollers can reduce the friction between the limit plate and the linkage flip table, making it easier for the gear flip part to slide smoothly on the top of the linkage flip table. Only when the gear flip part moves to the notch position, the gear flip part will drive the lower mold to rotate a certain angle under the drive of the linkage column. The gear flip part can be limited and fixed by the limit plate at other times. The gear flip part cannot rotate, has high stability, and can effectively prevent the lower mold from shaking.

[0046] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0047] Embodiment: As Figure 1-10 shown, a mold for a skylight plastic part of an automobile includes a base 1, on which a lifting module 2 and a linkage block 3 are fixedly arranged. The lifting of the upper mold 4 can be controlled by the lifting module 2 to facilitate the mold opening and closing operations. One side of the lifting module 2 is fixedly connected to the upper mold 4. A lower mold 5 is arranged below the upper mold 4. Mold flipping mechanisms 6 are symmetrically arranged on both sides of the lower mold 5. One side of the lifting module 2 is meshed with a sheave drive mechanism 7, and the mold flipping mechanism 6 is rotatably installed on the sheave drive mechanism 7 through a bearing. A trigger mechanism 8 and a mold flushing mechanism 9 are arranged inside one end of the base 1 away from the upper mold 4. A demolding mechanism 10 is inserted through the bottom of the lower mold 5;

[0048] The mold flipping mechanism 6 includes a rotating shaft rod 601 rotatably inserted through the sheave drive mechanism 7 through a bearing and a linkage flipping table 602 symmetrically fixedly arranged outside the base 1. One end of the rotating shaft rod 601 is fixedly connected to the lower mold 5, and the other end is fixedly connected to a gear flipping member 603. A notch 604 is formed on the linkage flipping table 602. Linkage columns 605 are fixedly arranged at equal intervals on one side of the linkage flipping table 602 above the notch 604. When some plastic debris remains in the cavity of the lower mold 5 and needs to be cleaned after the plastic mold has been used for a long time, continue to control the lifting module 2 to rise. The continuously rising lifting module 2 can drive the lower mold 5 to move to one side through the sheave drive mechanism 7. When the gear flipping member 603 on the mold flipping mechanism 6 moves to the notch 604 on the linkage flipping table 602, the gear flipping member 603 can be driven to rotate 180 degrees through the linkage column 605. When the gear flipping member 603 rotates, the lower mold 5 can be driven to flip through the rotating shaft rod 601, and some plastic debris remaining in the cavity of the lower mold 5 can be poured downward, so that the inside of the lower mold 5 can be quickly cleaned;

[0049] The gear flipping member 603 includes a flipping plate 6031 fixedly connected to one end of the rotating shaft 601, and the upper and lower ends of the flipping plate 6031 are symmetrically fixed with limit plates 6032, and rollers 6033 are equidistantly arranged on the limit plates 6032. A linkage tooth 6034 is arranged on one side of the flipping plate 6031, and the linkage tooth 6034 matches the linkage column 605. By arranging the roller 6033 on the limit plate 6032 on the gear flipping member 603, the roller 6033 can reduce the limit plate 6032. The friction between 032 and the linkage flip table 602 facilitates the smooth sliding of the gear flip part 603 on the top of the linkage flip table 602. Only when the gear flip part 603 moves to the slot 604 and is driven by the linkage column 605, the gear flip part 603 will drive the lower mold 5 to rotate a certain angle. The gear flip part 603 can be fixed by the limiting plate 6032 at other times. The gear flip part 603 cannot rotate, and has high stability, which can effectively prevent the lower mold 5 from shaking.

After cleaning, the upper mold 4 is controlled to descend through the lifting module 2. At this time, the lifting module 2 can be linked to drive the grooved wheel driving mechanism 7 to move in the opposite direction. When the grooved wheel driving mechanism 7 drives the lower mold 5 to move in the opposite direction and completes the reset, the upper mold 4 will also complete the mold closing at the same time, which is convenient to operate.
