[0029] Reference Figure 1 As shown, the utility model provides a technical solution: a bathtub heating and forming device, comprising a base 1, a lower mold 2 is installed on the inner wall of the base 1, four support columns 3 are fixedly connected to the surface of the base 1, a heating plate 4 is slidably connected to the surface of the support columns 3, a top plate 5 is fixedly connected to the end of the four support columns 3 away from the base 1, a driving cylinder 6 is fixedly connected to the surface of the top plate 5, an upper mold 11 is fixedly connected to the output end of the driving cylinder 6, two air ducts 7 are fixedly connected to the surface of the top plate 5, a fan blade 10 is installed on the inner wall of the air duct 7, and a lifting structure 8 is provided on the surface of the base 1. By providing the lifting structure 8, it is convenient to clamp the acrylic plate when die-casting the bathtub, so as to facilitate the die-casting of the bathtub, and then to facilitate the bathtub after die-casting from the mold. A limiting structure 9 is provided on the surface of the air duct 7. By providing the limiting structure 9, it is convenient to prevent dust from entering the air duct 7, so as to prevent dust from sticking to the surface of the bathtub during the die-casting of the bathtub, thereby reducing the quality of the bathtub.

[0030] The specific arrangement and function of the lifting structure 8 and the limiting structure 9 will be described in detail below.

[0031] Reference Figure 2 and Figure 3As shown, in this embodiment: the lifting structure 8 includes a threaded rod 81, which is rotatably connected to the surface of the base 1, and the arc surface of the threaded rod 81 is threadedly connected to a driving arm 82. Both ends of the driving arm 82 are fixedly connected to a frame 83, and the surface of the frame 83 is threaded with a screw 84, and one end of the threaded rod 81 is fixedly connected to a pressing plate 85. The surface of the driving arm 82 is slidably penetrated by two rectangular rods 86, and the two rectangular rods 86 are fixedly connected to the surface of the base 1. The end of the rectangular rod 86 away from the base 1 is fixedly connected to a rectangular block 87, and the support arm moves along the surface of the rectangular rod 86. The rectangular rod 86 has the effect of limiting the moving path of the support arm, thereby preventing the support arm from rotating when moving. The end of the threaded rod 81 away from the base 1 is fixedly connected to a turntable 88, and the cross section of the turntable 88 is cross-shaped. The rotation of the turntable 88 will drive the threaded rod 81 to rotate, and the turntable 88 has the effect of facilitating the rotation of the threaded rod 81. A plurality of anti-skid strips 89 are fixedly connected to one side of the pressing plate 85. The anti-skid strips 89 are rubber strips. The movement of the pressing plate 85 will drive the anti-skid strips 89 to move until the anti-skid strips 89 are tightly attached to the surface of the acrylic plate. The protective strips further improve the effect of clamping the acrylic plate.

[0032] Reference Figure 4 and Figure 5 As shown, specifically, the limiting structure 9 includes a bottom plate 91, the bottom plate 91 is fixedly connected to the arc surface of the air duct 7, a column 92 is fixedly connected to the surface of the base 1, a limiting plate 93 is slidably connected to the surface of the column 92, a latch 94 is slidably penetrated through the surface of the limiting plate 93, and two limiting holes 95 are provided on the surface of the column 92, and the size of the latch 94 matches the size of the limiting hole 95. A spring 96 is sleeved on the surface of the column 92, and the two ends of the spring 96 are fixedly connected to the column 92 and the limiting plate 93 respectively. The limiting plate 93 will move in the direction of the space air duct 7 with the help of the extension force of the spring 96, and the spring 96 can facilitate the movement of the position of the limiting plate 93. An arc strip 98 is fixedly connected to one side of the limiting plate 93 close to the air duct 7. An arc groove 97 is provided on the surface of the air duct 7. The size of the arc strip 98 matches the size of the arc groove 97. When the limiting plate 93 moves, it drives the arc strip 98 to squeeze the dustproof net until the dustproof net fits on the inner wall of the arc groove 97. The arc strip 98 achieves the effect of further increasing the limit of the dustproof net.

[0033] Working principle: when the acrylic plate of the die-cast bathtub needs to be clamped, first put the acrylic plate into the two frames 83 so that the acrylic plate covers the lower mold 2, and then turn the screw 84. The screw 84 will move in the frame 83 with the help of the thread. The movement of the screw 84 will drive the pressing plate 85 to move toward the acrylic plate. The movement of the pressing plate 85 will drive the anti-slip strip 89 to move until the anti-slip strip 89 fits tightly on the surface of the acrylic plate. The acrylic will fit tightly in the frame 83 with the help of the squeezing force of the pressing plate 85. Then turn the turntable 88. The rotation of the turntable 88 will drive the threaded rod 81 to rotate. The rotation of the threaded rod 81 will drive the threaded rod 81 to rotate. The support arm is driven to move, and the movement of the support arm will slide along the surface of the rectangular rod 86. The rectangular rod 86 limits the movement path of the support arm, thereby preventing the support arm from rotating when moving. The movement of the support arm will drive the frame 83 to move, and the movement of the frame 83 will drive the acrylic plate to move. When the acrylic plate moves to a suitable position, the acrylic plate is heated and die-casted. When the bathtub is formed, the turntable 88 is rotated in the opposite direction, and the turntable 88 will drive the threaded rod 81 to rotate, and the threaded rod 81 will drive the support arm to move. The movement of the support arm will drive the frame 83 to move, and the frame 83 will drive the formed bathtub to escape from the lower mold 2.

[0034] When it is necessary to prevent dust from entering the air inlet of the air duct 7, first pull the latch 94, which will move inside the limit plate 93 and gradually come out of the limit hole 95. When the latch 94 comes out of the limit hole 95, pull the limit plate 93 to move away from the air duct 7. The movement of the limit plate 93 will slide along the surface of the column 92. The movement of the limit plate 93 will compress the spring 96. When the limit plate 93 moves to a suitable position, insert the latch 94 into the limit hole 95 opened at the corresponding position. At this time, the spring 96 is in a compressed state, and then put the dust screen When the air inlet of the air duct 7 is reached, the dust-proof net covers the air inlet of the air duct 7, and then the latch 94 is pulled to make the latch 94 disengage from the limiting hole 95. At this time, the limiting plate 93 will drive the limiting plate 93 to move in the direction of the air duct 7 with the help of the stretching force of the spring 96. After the limiting plate 93 moves to a suitable position, it will squeeze the dust-proof net until the dust-proof net fits tightly to the surface of the air duct 7. When the limiting plate 93 moves, it will drive the arc strip 98 to squeeze the dust-proof net until the dust-proof net fits to the inner wall of the arc groove 97. The arc strip 98 achieves the effect of further increasing the limit of the dust-proof net.
