Description

Technical Field

[0001] This utility model relates to the technical field of thermoforming, specifically to a thermoforming device for lightweight foam boards. Background Technology

[0002] Airplane models are generally divided into two types: dynamic and static. Static models are used for collection and display and cannot fly. They are models that are scaled down to a certain proportion based on the image of an airplane. Dynamic models, on the other hand, can fly and can be controlled by remote control. Airplane models are generally made of foam board, but different styles of airplanes require thermoforming of the foam board to obtain the basic style of the airplane model.

[0003] For example, a utility model patent with Chinese patent announcement number CN206967822U discloses a foam board hot pressing molding device, including a first crossbeam, a first heating box and a second heating box. A second cylinder is provided in the middle of the first crossbeam, which can heat the foam board. After the foam board is deformed by heat, it can be quickly moved between the upper mold and the lower mold through the cooperation of the slide rail line and the slide rail, avoiding cooling caused by long-term movement.

[0004] However, the existing devices mentioned above fix the sheet metal by means of a slide rail. This fixing method has poor fixing effect and can cause the sheet metal to shift during processing, which in turn affects the thermoforming effect of the device on the sheet metal and makes it inconvenient to fix sheet metal of different sizes. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a lightweight foam board thermoforming device that improves the device's fixing effect on the board, facilitates fixing operations for boards of different sizes, improves the device's effect on subsequent thermoforming of the board, and enhances its practicality.

[0006] This utility model discloses a lightweight foam board thermoforming device, comprising a workbench and a second hot press plate. A fixing groove is formed at the top of the workbench, and a first hot press plate is attached to the top of the fixing groove. A power mechanism is provided at the top of the second hot press plate. Two fixing mechanisms are symmetrically arranged at the top of the workbench. Each fixing mechanism includes a movable plate, the outer wall of which is rotatably connected to the top of the workbench via two second connecting rods. Two first connecting rods are symmetrically fixedly installed on the outer wall of the movable plate, and a clamping plate is rotatably installed at the bottom of each first connecting rod. An inclined plate is obliquely fixedly installed at one end of the movable plate, and the bottom end of the inclined plate is fixedly connected to the outer wall of the workbench via multiple springs. An extension mechanism is provided at the top of the clamp; A limiting mechanism is provided on the outer wall of the inclined plate. This lightweight foam board thermoforming device, through the extension and contraction of the spring, synchronously drives the inclined plate and the moving plate to adjust their angle under the limitation of the second connecting rod. As the moving plate moves, it simultaneously drives the clamping plate to move longitudinally under the limitation of the first connecting rod. The clamping plate contacts the board at the top of the first hot press plate, thereby fixing the board. The second hot press plate and the first hot press plate perform thermoforming on the board, which improves the fixing effect of the device on the board, facilitates fixing of boards of different sizes, improves the effect of the device on the subsequent thermoforming of the board, and improves its practicality.

[0007] Preferably, the limiting mechanism includes a fixing block that fits against the outer wall of the inclined plate. A first screw is rotatably mounted on one end of the fixing block, and the other end of the first screw is screwed onto the outer wall of the worktable. By rotating the first screw, the fixing block is simultaneously moved laterally. As the fixing block moves, the angle of the rotating inclined plate is limited.

[0008] Preferably, the power mechanism includes a cylinder. A top plate is fixedly installed on the top of the worktable through multiple connecting columns. The cylinder is fixedly installed on the top of the top plate. The output end of the cylinder is fixedly connected to the top of the second hot press plate. Power is output through the bottom end of the cylinder, thereby synchronously driving the second hot press plate to perform longitudinal movement. The second hot press plate and the first hot press plate perform thermoforming operations on the sheet material at the top of the first hot press plate.

[0009] Preferably, the extension mechanism includes a sliding mechanism and a fixed plate. The bottom end of the fixed plate is at the same horizontal plane as the bottom end of the clamping plate. A sliding rod is horizontally fixedly installed on the top end of the fixed plate. The sliding rod is slidably connected to the top end of the clamping plate through the sliding mechanism. By sliding the sliding rod and the fixed plate, plates of different sizes and lengths can be fixed.

[0010] Preferably, the sliding mechanism includes a bracket, which is fixedly installed at one end of the clamping plate. A limit block is fixedly installed at the top of the bracket, and a limit groove is formed at the bottom of the limit block. The limit groove is slidably connected to the slide rod, and the slide rod slides on the limit groove to facilitate the lateral movement of the slide rod and the fixed plate.

[0011] Preferably, it also includes a support mechanism. The bottom end of the workbench is provided with multiple through holes, and the top of each through hole is provided with a support mechanism. By opening the through holes, the first hot press plate can be quickly separated from the fixed groove through the support mechanism.

[0012] Preferably, the support mechanism includes a second screw, which is screwed into the inner wall of the through hole. A support column is fixedly installed at the bottom end of the second screw. While the second screw is rotated by the support column, the top end of the second screw contacts the bottom end of the first hot press plate, thereby causing the first hot press plate to quickly detach from the fixing groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This lightweight foam board thermoforming device, through the extension and contraction of the spring, synchronously drives the inclined plate and the moving plate to perform angle adjustment under the limitation of the second connecting rod. Simultaneously, the movement of the moving plate, under the limitation of the first connecting rod, drives the clamping plate to perform longitudinal movement. The clamping plate contacts the board at the top of the first hot press plate, thereby fixing the board. The second and first hot press plates perform thermoforming on the board, improving the device's fixing effect on the board, facilitating fixing of boards of different sizes, improving the device's subsequent thermoforming effect on the board, and enhancing its practicality.

[0018] like Figures 1 to 4As shown, this utility model discloses a lightweight foam board thermoforming device. During operation, the extension and retraction of spring 9 synchronously drives the inclined plate 8 and the moving plate 4 to adjust their angles under the limitation of the second connecting rod 7. Simultaneously, the movement of the moving plate 4, under the limitation of the first connecting rod 5, synchronously drives the clamping plate 6 to move longitudinally.
