Description

Technical Field

[0001] This invention relates to the field of gypsum board processing technology, specifically to a rapid prototyping machine for gypsum boards. Background Technology

[0002] Gypsum board is a material made primarily from building gypsum. It is a lightweight, high-strength, thin, and easy-to-process building material with good sound insulation, heat insulation, and fire resistance properties, making it one of the new lightweight building materials currently under development. In the research and development of gypsum board, it is necessary to produce samples for experimentation to verify the parameters and performance of the gypsum board. Currently, sample forming mainly relies on manual operation without specialized equipment, reducing forming efficiency. Furthermore, it is difficult to control the thickness and pressure during the gypsum sample forming process, further reducing work efficiency. Summary of the Invention

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-5 The present invention provides a technical solution: a rapid molding machine for gypsum templates, including a base box 1, a fixed cylinder 2 vertically fixedly connected to the top of the base box 1, a base plate 3 set above the base box 1, a guide rod 4 fixedly connected to the bottom of the base plate 3, the bottom end of the guide rod 4 extending into the fixed cylinder 2 and movably connected to the fixed cylinder 2, thereby realizing that the base plate 3 can move up and down, which facilitates vibration compaction after filling.

[0025] A bottom mold 5 is provided on the top of the base plate 3, and a top mold 6 is provided above the bottom mold 5. The top mold 6 is slidably connected to the inner wall of the bottom mold 5. Therefore, the thickness of the gypsum board can be controlled according to the moving distance of the top mold 6, and the physical properties of the gypsum board at different thicknesses can be measured. A fixed column 7 is vertically fixedly connected to one side of the top of the base box 1. A fixed sleeve 8 is rotatably connected to the top of the fixed column 7. A fixed seat 9 is horizontally fixedly connected to one side of the fixed sleeve 8. A pressure device 10 is vertically provided on one side of the bottom of the fixed seat 9. The pressure device 10 adopts a hydraulic cylinder or an electric telescopic rod. When the top mold 6 needs to be disassembled, the pressure device 10 is rotated to the other side, which facilitates the disassembly and assembly of the filler and the top mold 6.

[0026] A vibration device is provided at the bottom of the base plate 3. The vibration device includes a lifting rod 22, a vibration motor 20, a connecting plate 19, a connecting frame 18, and a guide column 17. The lifting rod 22 and the guide column 17 are vertically arranged at the bottom of the inner wall of the base box 1. The connecting frame 18 is slidably connected to the guide column 17. The connecting plate 19 is fixed at the bottom of the base plate 3. The top of the connecting frame 18 is fixedly connected to the bottom of the connecting plate 19. The vibration motor 20 is fixed to the bottom of the connecting frame 18. Connecting seats 21 are fixedly connected to both sides of the connecting frame 18. A connecting rod 23 is vertically arranged at the movable end of the lifting rod 22. The top of the connecting rod 23 passes through the connecting seat 21 and is fixedly connected to a limit block 24. A second spring 25 is provided between the bottom of the connecting rod 23 and the movable end of the lifting rod 22. The lifting rod 22 is an electric telescopic rod. When vibration is required, the lifting rod 22 works to lift the base plate 3 and start the vibration motor 20. Since the connecting rod 23 is movably connected to the connecting seat 21, the second spring 25 prevents the entire device from vibrating when the vibration motor 20 is working.

[0027] Thickness adjustment devices are provided on both sides of the top of the top mold 6. The thickness adjustment device includes a fixed rod 11, a connecting block 13 is slidably connected to the surface of the fixed rod 11, and a cavity adapted to the fixed rod 11 is provided inside the connecting block 13. A slider 12 is fixedly connected to one end of the fixed rod 11 located in the cavity. A first spring 14 is provided between the bottom of the slider 12 and the cavity. An adjusting screw 15 is vertically threaded to one side of the connecting block 13. A pressure plate 16 is provided at the bottom end of the adjusting screw 15. By rotating the adjusting screw 15, the distance between the pressure plate 16 and the bottom of the bottom mold 5 can be adjusted. During the compaction process, the pressure plate 16 moves downward with the top mold 6. When it contacts the bottom mold 5, it indicates that the target thickness has been reached, and the pressure device 10 stops working. The reason for the movable connection between the connecting block 13 and the fixed rod 11 is to ensure that pressure can still be applied downward when the pressure plate 16 contacts the bottom mold 5. The distance between the connecting block 13 and the top mold 6, that is, the distance of downward movement after contact, can still achieve control of the thickness of the gypsum board.

[0028] A controller 26 is provided on one side of the interior of the base box 1, and a control panel 31 connected to the controller 26 is provided on the surface of the base box 1 for controlling the lifting rod 22 and the vibration motor 20.

[0029] Stabilizing seats 29 are fixedly connected to the top two sides of the base plate 3. Stabilizing bolts 30 are threadedly connected to the center of the stabilizing seats 29. The surface of the bottom mold 5 is provided with fixing grooves that are compatible with the stabilizing bolts 30, so as to fix the bottom mold 5.

[0030] A rib 28 is provided between one side of the fixing sleeve 8 and the top of the fixing seat 9.

[0031] A pressure sensor 27 is provided on the top of the top mold 6 and directly below the pressure application device 10. The pressure sensor 27 directly displays the compaction pressure, which facilitates pressure control during molding.
