[0025] Embodiment 2:

[0026] Figure 1-6The acrylic hot bending auxiliary positioning tooling of an embodiment of the utility model is shown, which includes: a plastic bending mold 1: the left and right sides of the plastic bending mold 1 are slidably connected with a hollow head 2, the inner wall of the hollow head 2 is fixedly connected with a multi-faceted head 3, the inner cavity of the hollow head 2 is slidably connected with an elastic slotted head 4, the bottom of the elastic slotted head 4 is fixedly connected with a connecting rod 5, the left and right sides of the plastic bending mold 1 are fixedly connected with a support plate 6, a spring 7 is welded between the top of the support plate 6 and the bottom of the hollow head 2, the bevel head 13 is located directly below the limit head 12, and the hollow head 2 It is slidably connected to the inner cavity of the limit plate 9, and the bevel head 1 8 is located between the limit head 12 and the bevel head 2 13. The inner cavity of the plastic bending mold 1 is slidably connected with a bending pressure plate 14. The bottoms of the left and right sides of the bending pressure plate 14 are respectively fixedly connected to two connecting rods 5. The hollow head 2 is fixedly connected to the side opposite to the plastic bending mold 1 with a bending plate 15.

[0027] Working principle: When the utility model is used, the user places the heated acrylic plate in the inner cavity of the plastic bending mold 1, and then places the bending surface pressure plate 14 in the inner cavity of the plastic bending mold 1, so that the bending surface pressure plate 14 is pressed against the surface of the acrylic plate. When the bending surface pressure plate 14 slides in the inner cavity of the plastic bending mold 1, the elastic slotted heads 4 on both sides of the bending surface pressure plate 14 will enter the inner cavity of the hollow head 2, and under the special shape of the inner wall of the elastic slotted head 4, and the support of the support plate 6 and the spring 7, the elastic slotted head 4 clamps the surface of the polygonal head 3, and then the hollow head 2 and the elastic slotted head 4 are used to fix the bending surface pressure plate 14 and the plastic bending mold 1. After the acrylic plate is bent, the bending pressure plate 14 is pulled upwards. At this time, under the positioning of the positioning plate 10 and the limiting head 12, the elastic slotted head 4 is removed from the surface of the polygonal head 3, so that the bending pressure plate 14 is separated from the inner cavity of the hollow head 2, or the hollow head 2 is pulled downwards, and with the cooperation of the bevel head 1 8 and the bevel head 2 13, the two positioning plates 10 are slid back to back, thereby ending the limiting of the hollow head 2 and separating the polygonal head 3 from the inner cavity of the elastic slotted head 4.
