[0001] The utility model relates to the technical field of bag production, in particular to a bag hot pressing molding die. Background Art

[0002] A molding mold, also known as a mold, is a mold made in proportion to the shape and structure of the actual object. It is a tool that uses pressing or pouring to make the material into a certain shape. When producing luggage, molds are generally used to process the luggage. With the continuous improvement of people's living standards, luggage is also constantly developing. Therefore, the molding molds used for luggage processing have also been continuously developed and innovated. They have basically met people's use needs, but there are still some problems.

[0003] At present, when producing bags, since the materials of bags are mostly high-density plastics, hot pressing is adopted during molding. However, since high-density plastics have a certain viscosity when molten, the convenient parts of the bags are easily adhered to the inner wall of the mold after molding and cooling, which makes it inconvenient to take out the molded bags.
