[0002] Melamine tableware, also known as imitation porcelain tableware, melamine tableware or scientific porcelain tableware, is a kind of polymer tableware formed by heating and pressing melamine resin powder. The main components of melamine tableware are melamine and formaldehyde, and usually do not contain heavy metals and harmful chemical substances. Therefore, it is considered a relatively safe tableware choice. They are light, beautiful, resistant to low temperature, boiling, and not easy to break, so they are widely used in the catering industry, especially in the children's catering industry. Melamine tableware is used in the temperature range of -20°C to 120°C, has food-grade safety, is non-toxic and odorless, and has high surface hardness, scratch resistance, good gloss and bright color.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-3 , the present invention provides a technical solution for a high-temperature-resistant melamine tableware molding machine: including a workbench 4, a first upper die 1, a second upper die 2 and a third upper die 3. A support rod 5 is provided at the top of the workbench 4. The support rod 5 is fixedly connected to the rear of the top of the workbench 4. The bottom of the support rod 5 is fixedly connected with a cylinder 6. The first upper die 1 is provided at the bottom of the cylinder 6. The first lower die 7 is provided in the middle of the top of the workbench 4. The second upper die 2 and the second lower die 9 are provided on the left side of the top of the workbench 4. The third upper die 3 and the third lower die 10 are provided on the right side of the top of the workbench 4. The bottom of the cylinder 6 is fixedly connected with a card slot 11. The tops of the first upper die 1, the second upper die 2 and the third upper die 3 are all fixedly connected with card blocks 12. The card blocks 12 are adapted to the card slots 11, and the card blocks 12 are clamped in the card slots 11.

[0020] Specifically, connection grooves 13 are provided on both sides of the card slot 11. The connection grooves 13 extend to the outside of the card slot 11. Connection blocks 14 are provided on both sides of the card block 12. The connection blocks 14 are adapted to the connection grooves 13, and the connection blocks 14 are movably connected inside the connection grooves 13.

[0021] Specifically, grooves 15 are provided on both sides of the card block 12. Springs 16 are provided inside the grooves 15. One end of the spring 16 is fixedly connected inside the groove 15, and the other end of the spring 16 is fixedly connected with a connection block 14.

[0022] Specifically, bottom plates 8 are provided at the bottoms of the first lower die 7, the second lower die 9 and the third lower die 10. The bottoms of the bottom plates 8 are fixedly connected with electric push rods 18. The bottoms of the electric push rods 18 are fixedly connected with fixed plates 19.

[0023] Specifically, suction cups 20 are fixedly connected to the bottom of the fixed plate 19. The number of the suction cups 20 is four and they are fixedly connected to the bottom corners of the fixed plate 19.

[0024] Specifically, a first storage box 21 is fixedly connected to the left side of the top of the workbench 4.
