Description

Technical Field

[0001] This utility model relates to the field of bending dies, and in particular to a multi-segment bending die for acrylic sheets. Background Technology

[0002] Acrylic sheet products refer to products made from acrylic sheets as raw materials through various processes such as cutting, carving, hot bending, bonding, and injection molding. They are widely used in both residential and commercial fields.

[0003] The core of acrylic sheet shaping is to first obtain the base material through casting / extrusion, and then use thermoforming (such as hot bending) or injection molding processes to achieve the target shape, while coordinating auxiliary processes such as cutting and bonding.

[0004] Existing molds for hot bending acrylic sheets cannot guarantee that the two sides of the acrylic sheet are straight after forming, requiring a second hot bending process, which affects the forming efficiency of the acrylic sheet. In addition, when an acrylic sheet needs to be hot bent in multiple sections, all hot bending positions need to be hot bent one by one, which is cumbersome and inefficient. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-segment bending mold for acrylic sheets.

[0006] According to one aspect of the present invention, a multi-segment bending mold for acrylic sheets is provided, comprising a base, a support plate, and a fixing clamp. The end of the support plate is fixed to the base, and the fixing clamp is disposed on the base. The fixing clamp is used to press and fix the acrylic sheet placed on the support plate. The mold also includes two side plates, the end of which is fixed to the base. One side plate is located on one side of the support plate, and the other side plate is located on the other side of the support plate. The longitudinal section of the side plate parallel to its length direction is arc-shaped. The number of fixing clamps is multiple, with at least two fixing clamps used to press and fix the acrylic sheet placed on one side plate and at least two fixing clamps used to press and fix the acrylic sheet placed on the other side plate.

[0007] This utility model relates to a multi-segment bending mold. A robotic arm places a heated acrylic sheet on a support plate, then presses both sides of the acrylic sheet against two side plates. A fixing clamp is used to press and fix the acrylic sheet to the support plate and the two side plates. After the acrylic sheet cools, the fixing clamp is released, and the formed acrylic sheet can be removed. This allows for the simultaneous hot bending of at least two segments of the acrylic sheet in one operation, eliminating the need to heat-bend each section individually. This simplifies the operation and improves the efficiency of hot bending. Furthermore, since the longitudinal sections of the two side plates, parallel to their length direction, are arc-shaped, a certain degree of interference deformation can be applied to the two sides of the acrylic sheet. After the hot-bent acrylic sheet cools, it ensures that the two sides of the acrylic sheet are straight, eliminating the need for secondary hot bending and further improving the forming efficiency of the acrylic sheet.

[0008] Furthermore, it also includes two intermediate support plates, the ends of which are fixed to the base. One intermediate support plate is located between the support plate and a side plate, and the other intermediate support plate is located between the support plate and another side plate. At least two fixing clips are used to press and fix the acrylic sheet placed on one intermediate support plate and at least two fixing clips are used to press and fix the acrylic sheet placed on the other intermediate support plate.

[0009] Therefore, the robotic arm places the heated acrylic sheet on the support plate, then presses the middle and side sections of the acrylic sheet onto two intermediate support plates, and presses the two sides of the acrylic sheet onto two side plates. The acrylic sheet is then fixed to the support plate, the two intermediate support plates, and the two side plates with clamps. After the acrylic sheet cools down, the clamps are released, and the formed acrylic sheet can be removed. This process completes the four-segment hot bending of the acrylic sheet at one time, eliminating the need to heat-bend each section individually. This simplifies the operation and improves the efficiency of hot bending.

[0010] Furthermore, there are twelve fixing clips, of which four fixing clips are used to press and fix the acrylic sheet placed on the support plate, two fixing clips are used to press and fix the acrylic sheet placed on one intermediate support plate, two fixing clips are used to press and fix the acrylic sheet placed on another intermediate support plate, two fixing clips are used to press and fix the acrylic sheet placed on one side plate, and two fixing clips are used to press and fix the acrylic sheet placed on another side plate.

[0011] Therefore, four fixing clips can firmly press and fix the acrylic sheet to the support plate to prevent the middle part of the acrylic sheet from warping during the hot bending process. Two fixing clips can firmly press and fix the part between the middle and one side of the acrylic sheet to an intermediate support plate. Two fixing clips can firmly press and fix the part between the middle and the other side of the acrylic sheet to another intermediate support plate to prevent the part between the middle and the side of the acrylic sheet from warping during the hot bending process. Two fixing clips can firmly press and fix one side of the acrylic sheet to a side plate. Two fixing clips can firmly press and fix the other side of the acrylic sheet to another side plate to prevent the side of the acrylic sheet from warping during the hot bending process.

[0012] Furthermore, the base includes a base plate, a left mounting plate, and a right mounting plate. The left mounting plate and the right mounting plate are respectively disposed on the base plate. The two ends of the support plate are respectively fixed on the left mounting plate and the right mounting plate. The two ends of the side plate are respectively fixed on the left mounting plate and the right mounting plate. The two ends of the middle support plate are respectively fixed on the left mounting plate and the right mounting plate.

[0013] Therefore, the left and right mounting plates can provide load-bearing capacity for the support plate, side plates, and middle support plate.

[0014] Furthermore, the base also includes a left support plate, a right support plate, and multiple connecting plates. The left support plate and the right support plate are respectively located at both ends of the base plate. The left support plate is located outside the left mounting plate, and the right support plate is located outside the right mounting plate. The left support plate and the left mounting plate are connected by connecting plates, and the right support plate and the right mounting plate are connected by connecting plates and fixedly clamped on the connecting plates.

[0015] Therefore, the connecting plate provides support for the fixing clamp, and the left support plate, right support plate, and connecting plate can improve the stability of the left mounting plate and right mounting plate.

[0016] Furthermore, it also includes at least one support plate, which is disposed on the base plate and located between the left mounting plate and the right mounting plate. The support plate is used to support the support plate and the intermediate support plate.

[0017] Therefore, the load-bearing plate can provide load-bearing capacity for the support plate and intermediate support plate, ensuring the stability of the support plate and intermediate support plate.

[0018] Furthermore, the left mounting plate, right mounting plate, left support plate, right support plate, and load-bearing plate are arranged in parallel.

[0019] Therefore, this simplifies the assembly of multi-segment bending dies.

[0020] Furthermore, the support plates are arranged horizontally, the middle support plates are arranged at an angle, and the side plates are arranged vertically.

[0021] Therefore, this allows the hot-bent acrylic sheet to have four bending points, forming an overall shape approximately C. The arrangement of the support plate, middle support plate, and side plates can be adjusted according to the shape requirements of the acrylic sheet.

[0022] Furthermore, the height difference between the highest point of the longitudinal section of the side plate, which is parallel to its length direction, and the end of the side plate is 5 mm.

[0023] Therefore, a height difference of 5mm can ensure that the two sides of the acrylic sheet are straight after the hot-bent acrylic sheet has cooled.

[0024] Furthermore, positioning protrusions are provided at both ends of the support plate.

[0025] Therefore, the acrylic sheet to be heat-bent has two slots in the corresponding positions. When the robotic arm places the heated acrylic sheet on the support plate, it ensures that the two slots on the acrylic sheet are respectively engaged with the two positioning protrusions on the support plate, ensuring that the acrylic sheet is placed in the correct position and will not move easily during the heat-bending process.

[0033] See Figures 1 to 4 A multi-segment bending mold for acrylic sheets includes a base 1, a support plate 2, a fixing clamp 3, two side plates 4, two intermediate support plates 5, and a bearing plate 6.

[0034] See Figure 1 and Figure 2 The base 1 includes a base plate 11, a left mounting plate 12, a right mounting plate 13, a left support plate 14, a right support plate 15, and multiple connecting plates 16. The left mounting plate 12 and right mounting plate 13 are respectively mounted (e.g., plugged in) on the base plate 11. The left support plate 14 and right support plate 15 are respectively mounted (e.g., plugged in) at both ends of the base plate 11. The left support plate 14 is located outside the left mounting plate 12, and the right support plate 15 is located outside the right mounting plate 13. The left mounting plate 12 and right mounting plate 13 are located between the left support plate 14 and the right support plate 15. Plate 12, right mounting plate 13, left support plate 14, and right support plate 15 are all arched in shape. The left support plate 14 is connected and fixed to the left mounting plate 12 by multiple connecting plates 16, and the right support plate 15 is connected and fixed to the right mounting plate 13 by multiple connecting plates 16. The left mounting plate 12 and right mounting plate 13 can provide load-bearing for the support plate 2, side plate 4, and middle support plate 5. The connecting plates provide load-bearing for the fixing clamp 3. The left support plate 14, right support plate 15, and connecting plates 16 can improve the stability of the left mounting plate 12 and right mounting plate 13.

[0035] See Figure 1 and Figure 2The support plate 6 is installed (e.g., by plugging) on ​​the base plate 11. There are multiple support plates 6 arranged in parallel. The support plate 6 is located between the left mounting plate 12 and the right mounting plate 13. The support plate 6 can provide support for the support plate 2 and the middle support plate 5, ensuring the stability of the support plate 2 and the middle support plate 5.

[0036] See Figure 1 and Figure 2 The left mounting plate 12, right mounting plate 13, left support plate 14, right support plate 15, and bearing plate 6 are arranged in parallel, which simplifies the assembly of multi-segment bending dies.

[0037] See Figure 1 and Figure 2 The two ends of the support plate 2 are fixed (e.g., by insertion) to the left mounting plate 12 and the right mounting plate 13 of the base 1, respectively. The two ends of the side plate 4 are fixed (e.g., by insertion) to the left mounting plate 12 and the right mounting plate 13 of the base 1, respectively. The two ends of the middle support plate 5 are fixed (e.g., by insertion) to the left mounting plate 12 and the right mounting plate 13 of the base 1, respectively. One side plate 4 is located on one side of the support plate 2, and the other side plate 4 is located on the other side of the support plate 2. One middle support plate 5 is located between the support plate 2 and one side plate 4, and the other middle support plate 5 is located between the support plate 2 and the other side plate 4. When the base 1 is placed on a horizontal surface, the support plates 2 are arranged horizontally. The intermediate support plates 5 are arranged at an angle, and the side plates 4 are arranged vertically. This allows the hot-bent acrylic sheet to have four bending positions. One bending position is formed between the support plate 2 and one intermediate support plate 5, another between the support plate 2 and another intermediate support plate 5, one between one intermediate support plate 5 and one side plate 4, and another between another intermediate support plate 5 and another side plate 4. A total of four bending positions can be formed on the acrylic sheet, so that the hot-bent acrylic sheet has an overall shape of approximately C. The arrangement of the support plate 2, intermediate support plate 5, and side plates 4 can be adjusted according to the shape requirements of the acrylic sheet.

[0038] See Figure 1 and Figure 2The left support plate 14 and the left mounting plate 12 are connected and fixed by five connecting plates 16. The positions of the five connecting plates 16 correspond to one end of the support plate 2, the two intermediate support plates 5, and the two side plates 4, respectively. The right support plate 15 and the right mounting plate 13 are connected and fixed by five connecting plates 16. The positions of the five connecting plates 16 correspond to the other ends of the support plate 2, the two intermediate support plates 5, and the two side plates 4, respectively. The fixing clip 3 is fixed on the connecting plates 16 of the base 1. The fixing clip 3 is used to press and fix the acrylic plate placed on the support plate 2, the intermediate support plate 5, and the side plate 4. This embodiment In this configuration, there are twelve fixing clips 3. Two fixing clips 3 are used to press and fix one side of the acrylic sheet placed on the support plate 2, two fixing clips 3 are used to press and fix the other side of the acrylic sheet placed on the support plate 2, one fixing clip 3 is used to press and fix one side of the acrylic sheet placed on an intermediate support plate 5, one fixing clip 3 is used to press and fix the other side of the acrylic sheet placed on the intermediate support plate 5, one fixing clip 3 is used to press and fix one side of the acrylic sheet placed on another intermediate support plate 5, and one fixing clip 3 is used to press and fix the acrylic sheet placed on the intermediate support plate 5. On the other side of the acrylic sheet on the support plate 5, a fixing clip 3 is used to press and fix one side of the acrylic sheet placed on one side plate 4, a fixing clip 3 is used to press and fix the other side of the acrylic sheet placed on that side plate 4, a fixing clip 3 is used to press and fix one side of the acrylic sheet placed on another side plate 4, and a fixing clip 3 is used to press and fix the other side of the acrylic sheet placed on that side plate 4. These four fixing clips 3 can firmly press and fix the acrylic sheet to the support plate 2, preventing the middle part of the acrylic sheet from warping during the hot bending process. Two fixing clips 3 can... The acrylic sheet is securely pressed and fixed to a middle support plate 5 between the middle and one side edge. Two fixing clips 3 can securely press and fix the acrylic sheet between the middle and the other side edge to another middle support plate 5, preventing the acrylic sheet between the middle and the side edge from warping during the hot bending process. Two fixing clips 3 can securely press and fix one side of the acrylic sheet to a side plate 4, and two fixing clips can securely press and fix the other side of the acrylic sheet to another side plate 4, preventing the side of the acrylic sheet from warping during the hot bending process.

[0039] See Figure 1 and Figure 2 In this embodiment, no improvement is made to the structure of the fixing clip 3. Existing fixing clip structures can be directly selected, as long as the structure of the fixing clip can achieve both pressing and loosening of the acrylic sheet.

[0040] See 2 to Figure 4 The longitudinal section of side plate 4, which is parallel to the length direction of side plate 4, is arc-shaped. Figure 4As shown in the diagram, this allows for a certain degree of interference deformation on both sides of the acrylic sheet during the hot bending process. After the hot-bent acrylic sheet cools, it ensures that both sides are straight, eliminating the need for secondary hot bending and improving the forming efficiency of the acrylic sheet. (See attached image.) Figure 4 In this embodiment, the height difference H between the highest point in the middle of the side plate 4 and the end of the side plate 4 is 5mm. The height difference of 5mm can ensure that the two sides of the acrylic sheet are straight after the hot-bent acrylic sheet is cooled. In other embodiments, the size of the height difference H between the highest point in the middle of the side plate 4 and the end of the side plate 4 can be adaptively adjusted according to the length of the acrylic sheet.

[0041] See Figure 1 and Figure 2 The support plate 2 has positioning protrusions 21 formed at both ends. The acrylic sheet to be heat-bent has two slots in the corresponding positions. When the robot places the heated acrylic sheet on the support plate 2, it ensures that the two slots on the acrylic sheet are respectively engaged with the two positioning protrusions 21 on the support plate 2, so as to ensure that the acrylic sheet is placed in the correct position and that the acrylic sheet will not move easily during the heat bending process.

[0042] See Figures 1 to 5 This utility model relates to a multi-segment bending mold. A robotic arm places a heated acrylic sheet 10 onto a support plate 2. Two slots 101 on the acrylic sheet 10 engage with two positioning protrusions 21 on the support plate 2. The robotic arm then presses the portion of the acrylic sheet 10 between its middle and sides onto two intermediate support plates 5, and presses both sides of the acrylic sheet 10 onto two side plates 4. Corresponding fixing clips 3 are used to press and fix the acrylic sheet 10 onto the support plate 2, the two intermediate support plates 5, and the two side plates 4. After the acrylic sheet cools, all the fixing clips 3 are released, and the formed acrylic sheet is bent... The acrylic sheet 10 can be removed, thus completing the four-segment hot bending of the acrylic sheet 10 simultaneously without having to hot bend each section individually. This simplifies the operation and improves the efficiency of hot bending. Furthermore, since the height difference between the highest point of the longitudinal section parallel to the length direction of the two side plates 4 and the end of the side plate is 5mm, a certain degree of interference deformation can be applied to both sides of the acrylic sheet 10. After the hot-bent acrylic sheet 10 cools, it ensures that both sides are straight, eliminating the need for secondary hot bending and further improving the forming efficiency of the acrylic sheet.

[0043] The above descriptions are merely some embodiments of this utility model, intended to illustrate the technical means of this utility model, and are not intended to limit the technical scope of this utility model. Any obvious improvements made to this utility model by those skilled in the art in conjunction with existing common knowledge fall within the protection scope of this utility model.
