[0002] MIM stands for Metal Powder Injection Molding, which is a new type of powder metallurgy near-net-shape molding technology formed by introducing modern plastic injection molding technology into the field of powder metallurgy. The main production process is: first, the solid powder is evenly mixed with the organic binder, and after granulation, it is injected into the mold cavity by an injection molding machine under the heated plastic state for curing and forming, and then the binder in the formed blank is removed by chemical or thermal decomposition methods, and finally the final product is obtained by sintering and densification. Compared with traditional processes, it has the characteristics of high precision, uniform organization, excellent performance, and low production cost.

[0003] During the production process of MIM, the surface of the product also needs to be sprayed to increase the product's oxidation resistance, corrosion resistance, wear resistance and make the product more beautiful.

[0004] At present, when spraying, the surface of the product is mainly sprayed by workers holding a spray gun. This method easily causes the liquid sprayed by the spray gun to splash on the workers, causing the workers to come into direct contact with the sprayed liquid, which may affect the health of the workers.

A horizontally arranged clamping cylinder 42 is fixedly connected to one side of each clamping plate 41 close to the corresponding side wall of the placement slot 21.

[0037] When the product is placed inside the placement groove 21, the four clamping cylinders 42 are started, and the four clamping cylinders 42 drive the four clamping plates 41 to abut against the product, thereby realizing the clamping process of the product.

[0038] The support block 2 is connected with a tilting assembly 7, and the tilting assembly 7 is used to drive the product inside the placement groove 21 to turn over.
