[0002] With the development of the automotive industry, vehicle models are becoming more and more diversified. Compared with ordinary sedans, SUV models have the characteristics of higher vehicle body and stronger passing ability; wider field of vision and better driving experience; stronger loading capacity; and more imposing appearance. Due to the higher chassis and body of SUV models, their rear doors are usually opened in a hatchback manner. When closing the rear door, the operator needs to operate the door through the handle box on the rear door. Currently, the rear door handle box is injection molded at high temperature and high pressure using engineering plastics as raw materials. Because the rear door handle box has an enveloping structure, it will shrink inward and deform after injection molding and cooling, resulting in problems such as large dimensional deviation of the product and poor vehicle installation clearance, which not only affects the aesthetics but also causes abnormal noises when the handle box is tightly held by hand and squeezed against the rear door.

[0003] Chinese Patent No. CN214111226U discloses a shaping tool for an automotive rear door handle box. When using this device, hold the handle and pull the pull rod counterclockwise outward. The connecting rod drives the pressure rod to lift upward counterclockwise. After slipping the just injection molded handle box at high temperature and high pressure onto the tire mold, pull the pull rod clockwise inward to return to its original position, and the pressure block presses the bottom of the handle box. After the handle box is completely cooled and shaped, pull the pull rod to drive the pressure block to open upward, and then take out the handle box from the tire mold.

[0004] The applicant found the following technical problems when implementing the above technical solution:

[0005] When using this device, it is necessary to always hold the handle by hand. Otherwise, when the friction at the rotating shaft is less than the gravity of the pressure block, it will return to its original position under the action of the gravity of the pressure block, or fall to the other side of the tire mold, which will affect the shaping effect of the handle box and reduce the work efficiency.

[0006] Therefore, it is an urgent problem to be solved by the utility model to provide a shaping tool for a rear door handle box of a vehicle that does not require continuous hand holding after pulling up the pull rod. Summary of the Utility Model
