[0002] Molding is the abbreviation of compression molding, also known as compression molding; a plastic processing method in which plastic or rubber compounds are formed into products by heating and pressurizing in a closed mold cavity. When processing plastic tableware, molding is mainly used for production. Generally, powder, granules, pellets, and sheets are placed in the mold cavity of a heated mold, and then the mold is closed and pressurized to form and solidify or vulcanize it, and then the product is demolded.

[0020] like Figure 1 The figure is a schematic diagram of the structure of a molding device for processing plastic tableware provided in this embodiment.

[0021] In this embodiment, the structure is mainly as follows Figure 1As shown, it includes a base 1, a die pressing table 2, and a demolding table 3. A rotating table 4 is arranged on the base 1. A rotating motor 5 is arranged on the side of the rotating table 4 to facilitate driving the rotating table 4 to rotate and thereby drive the lower mold 6 to rotate. A lower mold 6 with equal spacing in a ring shape is arranged on the top edge of the rotating table 4. The die pressing table 2 is arranged on one side of the rotating table 4, and the demolding table 3 is arranged on the other side of the rotating table 4. A spraying table 7 is arranged next to the rotating table 4, and the spraying table 7 is arranged before the die pressing. A cooling fan 8 is arranged next to the rotating table 4, and the cooling fan 8 is arranged before demolding. The cooling fan 8 is arranged above the lower mold 6 to facilitate rapid cooling of the lower mold 6. The spraying table 7, the die pressing table 2, the cooling fan 8, and the demolding table 3 are distributed around the rotating table 4 to facilitate continuous and uninterrupted molding of plastic tableware.

[0022] A fixing frame 9 is arranged on the top of the die pressing table 2, an electric push rod 10 is arranged at the bottom of the fixing frame 9, an upper mold 11 is arranged at the bottom of the electric push rod 10, and the upper mold 11 is arranged above the lower mold 6 to facilitate molding of plastic tableware.

[0023] A rotating motor 12 is arranged at the bottom of the demoulding table 3, and the rotating motor 12 is connected to the rotating shaft 13, so as to drive the suction cup 18 to rotate. A rotating shaft 13 is arranged on the demoulding table 3, and a lifting platform 14 is arranged on the rotating shaft 13. A lifting motor 15 is arranged on the side of the lifting platform 14, so as to drive the suction cup 18 to rise and fall.
