[0001] The utility model relates to the technical field of cleaning rotomolding molds, in particular to a rust removal device for the inner cavity of a rotomolding mold. Background Art
[0002] Roto-molding molds, also known as rotational molding molds, are tools used to shape plastic products in the rotational molding process. Plastic raw materials are added to the mold, and then the mold is continuously rotated and heated. Under the action of gravity and heat energy, the plastic raw materials are gradually and evenly coated, melted and adhered to the entire surface of the mold cavity, forming into the required shape, and then cooled and shaped into the product.
[0003] During the rotational molding process, some plastic raw materials will decompose and produce volatile gases after heating. These gases are often corrosive and will cause rust if they act on the mold cavity for a long time. Therefore, professional cleaning agents are needed to remove the rust. The general cleaning method is to use a high-pressure water gun to spray the cleaning agent and use the impact force and pressure to remove the rust in the inner cavity. However, this method requires manual operation, which is time-consuming and labor-intensive. Therefore, a rust removal device for the inner cavity of the rotational mold is needed.

[0026] A screw rod 6 is provided inside the adjustment seat 3, and a driving block 5 is sleeved on the screw rod 6, and one side of the driving block 5 is connected to the lifting plate 4;
[0027] A first rotary drive mechanism 7 is fixed to the top of the adjustment seat 3, and the output end of the first rotary drive mechanism 7 is connected to the screw rod 6;
[0028] The first rotary drive mechanism 7 drives the screw 6 to rotate, causing the drive block 5 to rise or fall along the screw 6, adjusting the height position of the roller 13 so that it is flush with the inner cavity of the rotational molding mold body, and then the cylinder 8 drives the frame 10 to move and extend into the inner cavity of the rotational molding mold body;
[0029] Both ends of the frame 10 are provided with high-pressure nozzles 11, which are connected to the cleaning agent storage device through a water pipe. The cleaning agent is sprayed through the high-pressure nozzles 11, and the rust in the inner cavity is first washed away by the impact force and pressure of the high-pressure water flow;
[0030] The high-pressure nozzles 11 are all arranged in an inclined shape, and the outlet ends of the high-pressure nozzles 11 are all provided with uniform distribution covers 21, and the uniform distribution covers 21 are all circular porous structures, so that the cleaning agent sprayed out is more uniform;
[0031] A roller 13 is provided at the central position of the frame 10 away from the lifting plate 4. A rotating member 12 is evenly provided on the outer side of the roller 13 through a buffer cylinder 16, and brushes 15 are evenly distributed on the rotating member 12.
[0032] A second rotary drive mechanism 9 is fixed at the central position of the frame 10 near the lifting plate 4, and the output end of the second rotary drive mechanism 9 is connected to the roller 13 through a roller;

The buffer rod 17 on one side of the rotating member 12 can squeeze the buffer spring 14 in the buffer cylinder 16. The elastic characteristics of the buffer spring 14 enable the rotating member 12 to contact the inner wall of the rotational mold body with different inner diameters, thereby improving applicability.
