An acrylic bathtub molding system

technical field

The utility model relates to the technical field of bathtub production, in particular to an acrylic bathtub molding system.

Background technique

The acrylic bathtub is a bathtub made of a PMMA plastic material. The acrylic bathtub cylinder is composed of a surface layer (acrylic layer) and an inner layer (glass fiber resin reinforcement layer). Acrylic bathtubs are characterized by rich shapes, light weight, and good surface finish.

For example, the Chinese invention patent whose patent notification number is CN65128240A discloses a bathtub forming device, which includes a heating device for heating the acrylic plate, a clamping device for clamping the edge of the heated and softened acrylic plate, and an air pressure device , the force provided by the air pressure device evenly acts on the acrylic plate within the range of the clamping area to deform it into a curved plate, and the curved plate is clamped and fixed in the cavity of the forming mold.

When using the above-mentioned bathtub forming device, when the acrylic plate is formed, the acrylic plate will eventually be depressed toward the cavity of the forming mold, so that the acrylic plate fits in the mold and is formed. During the molding process of the bathtub, the whole acrylic plate is located in the molding cavity, which makes it inconvenient to observe the forming condition of the acrylic plate in the cavity of the molding mold, which needs to be improved.
