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 thereon. 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 demoulding mechanism can be squeezed upward by using the extrusion slope on the linkage block.

[0016] 2. For the mold of the plastic part of the sunroof of the car, when the plastic mold has been used for a long time and some plastic debris remains in the cavity of the lower mold and needs to be cleaned, the lifting module is controlled to rise continuously, 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 cavity of the lower mold can be poured downwards, so that the inside of the lower mold can be quickly cleaned.

[0017] 3. This mold for the plastic sunroof of a car, when the mold flipping mechanism drives the lower mold to flip, one side of the lower mold will contact the trigger mechanism, and the trigger mechanism can be linked to open. The trigger mechanism after linkage opening will automatically control the mold flushing mechanism to open. The mold flushing mechanism can be used to 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 affecting the appearance quality and structural strength of the plastic molded sunroof plastic parts. 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.

[0018] 4. This mold for the plastic part of the sunroof of a car has a roller arranged on the limit plate on the gear flip part. The roller can reduce the friction between the limit plate and the linkage flip table, so that the gear flip part can 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, and the gear flip part cannot rotate. It has high stability and can effectively prevent the lower mold from shaking.
