[0013] Further, the bottom surface of the lifting part is connected with the top surface of the driving block, the rear mold is provided with a through hole for the lifting part to pass through, and the driving block can drive the lifting part to move up and down. The power oil cylinder transmits power to the driving block to drive the lifting part mounted on the driving block to move up and down.

[0014] Further, an oil cylinder support is further included, the oil cylinder support is arranged on the bottom surface of the rear mold through bolts, and the power oil cylinder is arranged on the oil cylinder support.

[0015] Further, the lifting part and the driving block are connected through bolts.

[0016] The above technical scheme can achieve the following beneficial effects:

[0017] 1. The blow molding hanging table structure forming mold has the advantages that a hanging table mold with a groove is designed on the mold, the glue is forced to enter the groove to form the product wall thickness when the lifting part is lifted, then the lifting part is lowered to retreat, and the blow molding forms the hanging table positioning structure, so that the blow molding product has the hanging table positioning structure, and the wall thickness of the positioning structure is uniform and moderate.

[0018] 2. The blow molding hanging table structure forming mold can achieve the purposes of simplifying the mold structure and reducing the production cost. DRAWINGS
