Description

Technical Field

[0001] The utility model relates to the field of acrylic bathtub processing devices, in particular to a demoulding device for acrylic bathtub molding processing. Background Art

[0002] An acrylic bathtub is a bathtub made of a PMMA plastic material. The acrylic bathtub body is composed of a surface layer (acrylic layer) and an inner layer (glass fiber resin reinforcement layer). It has rich shapes, light weight, good surface finish, and low price. However, acrylic material has the disadvantages of poor high temperature resistance, pressure resistance, wear resistance, and easy aging of the surface. When producing acrylic bathtubs, they need to be shaped by a forming mold, and then the formed acrylic bathtub is removed from the mold by a demoulding device.

[0003] Chinese utility model patent document CN220482350U discloses a device for demolding acrylic bathtub blanks, relating to the field of acrylic bathtub production. The device comprises a frame, wherein two sets of screws are mounted on bearings above the frame, each of which is threaded with a threaded sleeve. A mounting bracket is fixed below the two sets of threaded sleeves, and multiple sets of pneumatic telescopic rods (1) are disposed below the mounting bracket, each of which is provided with a pneumatic suction cup. The pneumatic suction cups are used to absorb the acrylic bathtub, and then a motor drives the screws to rotate, causing the threaded sleeves to move, thereby moving the acrylic bathtub to one side of the frame. This makes it easier for workers to remove the bathtub. Because the horizontal bathtub processing equipment itself is equipped with a vacuum pump, the vacuum pump acts on the pneumatic suction cup, pneumatic telescopic rods (1), and pneumatic telescopic rods (2), eliminating the need for additional power equipment and saving equipment costs. However, the following shortcomings still exist.

[0004] In the above-mentioned prior art, the mounting frame of the demoulding device is movably mounted to the outside of the drive shaft via a threaded sleeve. The mounting frame is located directly above the mold, and a number of pneumatic suction cups are provided at the bottom of the mounting frame. After the pneumatic suction cups remove the acrylic bathtub from the mold, the mounting frame is driven horizontally by the drive shaft via the threaded sleeve. However, the existing demoulding device cannot completely remove the acrylic bathtub from the device after it is removed. Therefore, the inventors have proposed a demoulding device for acrylic bathtub molding processing to solve the above-mentioned problem. Summary of the Invention
