[0025] A fixing frame 3 is hingedly connected to the rack 1 at one end, and a pressing plate 31 is arranged at the circumferential edge of the fixing frame 3. After the bottom basin base is placed on the rack 1, the skirt edge is pressed tightly on the limiting plate 21 by the pressing plate 31 to fix the bottom basin base on the rack 1;

[0026] A locking device 4 is arranged on the rack 1, and the other end of the fixing frame 3 is detachably connected to the rack 1 by the action of the locking device 4;

[0027] A vacuum pump is connected in communication with a ventilation opening 22 in the bottom wall of the forming die 2 through an air pipe.

[0028] In the embodiment, the bottom basin body is preferably made of ABS material or acrylic material, and the skirt is arranged at the circumferential edge of the bottom basin body. The forming mold 2 is arranged on the rack 1, and the limiting plate 21 is arranged at the circumferential edge of the forming mold 2. The pressing plate 31 is arranged at the circumferential edge of the fixing frame 3. First, the bottom basin body is heated in the heating box to soften the bottom basin body. After the bottom basin body is softened, the bottom basin body is placed on the rack 1. The other end of the fixing frame 3 is locked with the rack 1 by the locking device 4, so that the bottom wall of the bottom basin body abuts against the limiting plate 21, and the bottom wall of the pressing plate 31 is pressed against the top wall of the bottom basin body. Thus, the skirt is pressed against the limiting plate 21 by the pressing plate 31, and the circumferential edge of the bottom basin body is fixed on the rack 1. Then, the vacuum pump is started to pump air in and out to remove the air in the forming mold 2, so that the bottom basin body is tightly attached to the inner wall of the forming mold 2, thereby forming the shape of the shower room bottom basin. Then, the formed shower room bottom basin is cooled to obtain the finished product. The structure is simple, easy to operate, can effectively fasten and press the four sides of the bottom basin body, prevent displacement of the bottom basin body during plastic suction, and effectively reduce the production cost of the product.

[0029] Further, the locking device 4 includes a locking tongue 41, a buckle body 42 and a locking ring 43.
