[0002] Acrylic is a thermoplastic material that can be softened by heating to a certain temperature and then molded into shape. Usually, when acrylic is heated to the corresponding softening point, it can be bent and folded according to the required shape to create various shaped products.

[0003] After being heated, acrylic sheets need to be placed into specific molds for shaping. For example, U-shaped acrylic sheets require the heated acrylic sheet to be placed into the inner cavity of a U-shaped support, and the acrylic sheet is shaped by the cooperation of a U-shaped abutment. In order to make the U-shaped abutment more stable when it leaves the inner cavity of the U-shaped support, an acrylic sheet hot bending mold positioning device is designed. This device uses the operation of a threaded rod to allow the U-shaped abutment to slide in a straight line into the inner cavity of the U-shaped support. This guides the U-shaped abutment when it slides into the inner cavity of the U-shaped support and makes it more stable when it leaves the inner cavity of the U-shaped support, so as to minimize the skew of the U-shaped abutment when it leaves the inner cavity of the U-shaped support.

[0022] In the following description, embodiments of the acrylic sheet hot bending mold positioning device of the present invention will be described with reference to the accompanying drawings.

[0023] Example 1:

[0024] Figure 1-4 This invention illustrates an acrylic sheet hot bending mold positioning device according to an embodiment of the present invention, comprising: a support box 1; a servo motor 2 is bolted to the left side of the support box 1; a threaded rod 3 is rotatably connected to the inner cavity of the support box 1; the output shaft of the servo motor 2 passes through the inner cavity of the support box 1 and is fixedly connected to the left end of the threaded rod 3 via a flange; a perforated sleeve 4 is threaded to the surface of the threaded rod 3; a limit groove 5 is formed on the top of the support box 1; a vertical rod 6 is bolted to the top of the perforated sleeve 4; an L-shaped support plate 7 is bolted to the top of the vertical rod 6; a U-shaped abutment 8 is bolted to the inner cavity of the L-shaped support plate 7; a U-shaped support 9 is bolted to the top of the support box 1; and L-shaped supports are welded to both the front and rear sides of the inner cavity of the support box 1. L-shaped guide 10 and L-shaped guide 10 are both bolted to support rods 11 on both the front and rear sides of the open sleeve 4. The opposite ends of the two support rods 11 are welded with protrusions 12. The surface of the vertical rod 6 is slidably connected to the inner cavity of the limiting groove 5. The U-shaped support 9 is located on the right side of the U-shaped contact 8. The surface of the U-shaped contact 8 is slidably connected to the inner cavity of the U-shaped support 9. The surface of the protrusion 12 is slidably connected to the inner cavity of the L-shaped guide 10. A rotating wheel 13 is installed at the bottom of the protrusion 12. The surface of the rotating wheel 13 is slidably connected to the inner cavity of the L-shaped guide 10. By setting the rotating wheel 13, the friction between the protrusion 12 and the L-shaped guide 10 can be reduced while the support rod 11 and the protrusion 12 are sliding in a straight line, so that the open sleeve 4 can slide more smoothly.

[0025] Example 2:

[0026] Figure 1-4 This invention illustrates an acrylic sheet hot bending mold positioning device according to an embodiment of the present invention, comprising: a support box 1; a servo motor 2 is bolted to the left side of the support box 1; a threaded rod 3 is rotatably connected to the inner cavity of the support box 1; the output shaft of the servo motor 2 passes through the inner cavity of the support box 1 and is fixedly connected to the left end of the threaded rod 3 via a flange; a perforated sleeve 4 is threaded to the surface of the threaded rod 3; a limit groove 5 is formed on the top of the support box 1; a vertical rod 6 is bolted to the top of the perforated sleeve 4; an L-shaped support plate 7 is bolted to the top of the vertical rod 6; a U-shaped abutment 8 is bolted to the inner cavity of the L-shaped support plate 7; a U-shaped support 9 is bolted to the top of the support box 1; and the front and rear sides of the inner cavity of the support box 1 are... The open sleeve rod 4 is welded with an L-shaped guide 10. The front and rear sides of the open sleeve rod 4 are fixedly connected with support rods 11 by bolts. The opposite ends of the two support rods 11 are welded with protrusions 12. The bottom of the open sleeve rod 4 is equipped with a double-layer rotating wheel 14. The surface of the double-layer rotating wheel 14 is rolled and connected to the bottom of the inner cavity of the support box 1. The double-layer rotating wheel 14 can provide support to the bottom of the open sleeve rod 4, which can prevent the open sleeve rod 4 and the threaded rod 3 from tilting due to the pressure of the U-shaped contact member 8. At the same time, it can make the open sleeve rod 4 slide more smoothly. The bottom of the support box 1 is fixedly connected with a support base 15 by bolts. The front and rear sides of the support box 1 are fixedly connected with L-shaped plates 16 by bolts. The U-shaped support member 9 is fixedly connected to the L-shaped plate 16 by bolts.

[0027] Working Principle: In use, the user places the heated acrylic sheet into the inner cavity of the U-shaped support 9, ensuring the acrylic sheet fits as closely as possible to the inner wall of the U-shaped support 9. Then, the servo motor 2 is activated, driving the threaded rod 3 to rotate. Under the action of the thread, the opening sleeve 4 slides on the surface of the threaded rod 3. This, along with the vertical rod 6 and the L-shaped support plate 7, causes the U-shaped contact piece 8 to slide towards the U-shaped support 9. As the U-shaped contact piece 8 approaches the U-shaped support 9, the operator can adjust the acrylic sheet to ensure its surface fits more closely to the inner wall of the acrylic sheet. Once the U-shaped contact piece 8 has slid to its designated position... When the servo motor 2 stops the threaded rod 3 from rotating, the position of the U-shaped abutment 8 is fixed, which in turn allows the acrylic plate inside the U-shaped support 9 to achieve a better shaping effect. After the shaping is completed, the servo motor 2 is started again to drive the U-shaped abutment 8 to slide. At this time, the cooperation of the L-shaped guide 10, the protrusion 12 and the rotating wheel 13 can make the U-shaped abutment 8 maintain a straight sliding better. This allows the U-shaped abutment 8 to be guided when sliding into the inner cavity of the U-shaped support 9, and to be more stable when leaving the inner cavity of the U-shaped support 9, so as to minimize the skewness of the U-shaped abutment 8 when leaving the inner cavity of the U-shaped support 9.

[0028] In summary, this acrylic sheet hot bending mold positioning device, by starting the servo motor 2 to drive the threaded rod 3 to rotate, causes the threaded rod 3 to drive the opening sleeve 4 and the U-shaped abutment 8 to slide, thereby keeping the U-shaped abutment 8 sliding in a straight line into the inner cavity of the U-shaped support 9 and shaping the acrylic sheet. This achieves the goal of guiding the U-shaped abutment 8 when sliding into the inner cavity of the U-shaped support 9 and making it more stable when leaving the inner cavity of the U-shaped support 9, so as to minimize the skewness of the U-shaped abutment 8 when leaving the inner cavity of the U-shaped support 9.
