[0002] Melamine tableware is a type of tableware made of melamine resin powder that is heated, pressurized and die-cast. Melamine plastic tableware is also called porcelain-like tableware. It is lightweight, beautiful, resistant to low temperatures (can be placed directly in the refrigerator), resistant to boiling (can be steamed or boiled in boiling water), resistant to pollution, and not easy to break. It is widely used in the fast food industry and children's catering industry, and is deeply loved by consumers and children. It also has the advantages of a smooth surface and easy cleaning.

[0003] A melamine tableware forming and demolding device is disclosed in the Chinese patent application disclosure specification CN219564106U. When in use, the staff holds the handle to push the ejector rod upward, and the raised ejector rod ejects the ejector ring from the ring groove in the mold base. The ejected ejector ring contacts the overflowed molded part on the mold base, and the melamine tableware in the mold can be lifted out at the same time, thereby realizing the demolding work. During the demolding process, the overall force is uniform and the ejection is smooth, and the melamine tableware body will not be deformed due to the squeezing force.
