The utility model relates to the technical field of forming moulds, in particular to a plastic barrel forming mould.

Background technique:

Mold is an important process equipment for the production of industrial products. In modern industrial production, most industrial products need to be produced by molds, but the existing molding dies on the market are poor due to their own stability and deformation resistance. As a result, it is easy to cause overflow of the molding liquid during the molding, contaminating the mold, and wasting resources, and the existing molding mold does not have the function of rotation, which causes the pouring of the higher concentration of the casting liquid to be slow, and the filling of the mold chamber It is not dense, and the phenomenon of bubbles is generated, which leads to a decrease in the quality of the product. At the same time, when the existing molding die is cooled after the mold is poured, the cooling of the mold is uneven due to uneven arrangement of the cooling ports, which affects the hardness of the product after molding.plastic pail mould
