Technical Field

[0001] The utility model relates to the technical field of oil tank production roto-molding equipment, in particular to a novel roto-molding device for producing oil tanks. Background Art

[0002] The basic process of rotational molding is very simple, that is, placing powdered or liquid polymer in a mold, heating it and rotating it around two perpendicular axes (rotation and revolution), and then cooling it. At the beginning of the heating stage, if powdered material is used, a porous layer is first formed on the mold surface, and then gradually melts during the cycle, finally forming a box with uniform thickness.

[0003] After the oil tank of the existing device is manufactured, the manufactured oil tank is generally embedded in the device, and most of the manufactured box bodies have no fulcrum, resulting in that the manufactured oil tank is difficult to be pulled out from the device.

[0004] After searching, it was found that the patent publication number CN214447888U discloses a new type of rotational molding device for producing oil tanks. The device drives the partition to move through the cooperation of a driving motor and a threaded rod, so that the oil tank manufactured in the rotational molding cavity can be easily taken out. However, the driving motor, threaded rod and other components are in a fixed box. When the driving motor is maintained and repaired in the later stage, the fixed box needs to be disassembled, which brings great inconvenience to the later maintenance of the device.
