It cannot change different molds according to production needs to produce bathtubs of different shapes, cannot quickly clean the inside of the bathtub mold to reduce the occurrence of processing failures and defective products due to the presence of debris and dust inside during processing, cannot quickly heat the sheet material to ensure better molding in the mold, improve the molding quality and appearance of the bathtub, and cannot quickly change different pressing molds to press the heated sheet material. Therefore, a utility model is proposed to solve the above problems. Utility Model Content

The heating motor 17 drives the heating screw 18 to rotate, causing the upper heating seat 19 to move up and down on one side of the heating frame 4. 9. Move downwards to the sheet material rack 14. The lower heater 16 and upper heater 20 are activated to heat the acrylic sheet material inside the sheet material rack 14, quickly softening it. Hydraulic bolts 113 allow for rapid installation and removal of the forming mold 114 under the hydraulic plate 112, facilitating worker replacement of the appropriate forming mold 114 according to the bathtub mold 10. After the acrylic sheet material is heated, the moving motor 12 drives the moving screw 13 to rotate, moving the sheet material rack 14 within the moving slide rail 2 to the forming base plate 1. The forming hydraulic press 111 then drives the hydraulic plate 112. The lower forming mold 114 extends and retracts vertically, pressing the heated acrylic sheet downwards. After the bathtub is finished, the worker takes the cleaning head 502 and turns on the filter pump 504. The filter pump 504 rotates, causing the cleaning head 502 to draw out debris and dust from the bathtub mold 10 and suck it into the cleaning box 501, which can quickly clean the inside of the bathtub mold 10. This device can quickly change the mold, significantly reducing mold change time, improving overall production efficiency, and can change different molds according to production needs.
