[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0013] This decorative gypsum board production line uses an automatic mold opening device for composite templates. Thanks to the structure of the cam and corrugated plate, the motor drives the rotating shaft and the cam to rotate. The cam continuously contacts the corrugated block. Because the corrugated block is corrugated, the slot vibrates, and a gap is created between the composite template and the slot, making it easier to remove the composite template. Compared with the traditional automatic mold opening device for composite templates in decorative gypsum board production lines, which has a weaker vibration demolding ability, this structure increases the vibration demolding ability, making it easier for the gypsum board to be smoothly removed from the mold, improving the decorative effect of the product, ensuring the product meets quality standards, and reducing the scrap rate.

[0014] This decorative gypsum board production line uses an automatic mold opening device with composite templates. Thanks to the structure of the compression spring, the mold squeezes the composite template of the decorative gypsum board production line into the slot, the slot squeezes the buffer plate and the sliding column, and the sliding column squeezes the compression spring. Finally, the decorative gypsum board production line uses composite templates to form the final product. This structure increases the buffer capacity, can absorb excess kinetic energy, reduce impact and collision, avoid damage to equipment and molds, and at the same time reduce noise and improve the reliability and service life of the equipment.

[0023] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0024] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0025] like Figures 1 to 5 The diagram illustrates an automatic mold-opening device for composite templates used in a decorative gypsum board production line. It includes a support platform 1 for supporting the composite templates. Four hollow columns 4 are symmetrically welded to the top of the support platform 1. Each hollow column 4 contains a compression spring 401. A sliding column 402 is connected to the end of each compression spring 401 away from the support platform 1. A buffer plate 301 is connected to the end of each sliding column 402 away from the compression spring 401. A slot 3 is provided at the top of the buffer plate 301, and a corrugated block 503 is installed at the bottom of the slot 3. U-shaped grooves 404 are provided on the outer periphery of each hollow column 4. A position sensor 403 is installed inside each hollow column 4. An electric... Machine 5, the output shaft of motor 5 is connected to rotating shaft 501 through coupling. A cam 502 is welded to one end of rotating shaft 501. The slot 3 squeezes the buffer plate 301 and slide column 402. The slide column 402 squeezes the compression spring 401. Finally, the decorative gypsum board production line is formed by composite template. The movable part of electric telescopic rod 105 is shortened and motor 5 is turned on. Motor 5 drives rotating shaft 501 and cam 502 to rotate. Cam 502 continuously contacts corrugated block 503. Since corrugated block 503 is corrugated, slot 3 vibrates. The decorative gypsum board production line composite template in slot 3 creates a gap with slot 3, increasing the vibration demolding ability and facilitating the smooth release of gypsum board from the mold.

[0026] The vertical inner wall of the slot 3 is welded with a slide rail 306, and a base plate 307 is slidably installed on the top of the slide rail 306. When it is necessary to remove the composite template for the decorative gypsum board production line, the base plate 307 can be removed from the sealing plate 103.

[0027] A third guide post 302 and a fixing plate 104 are welded to the top of the support platform 1. A threaded groove 303 is provided on the top of the third guide post 302, and a bolt 304 is rotatably connected inside the threaded groove 303. A protective frame 107 is welded to the side of the fixing plate 104, and an electric telescopic rod 105 for automatic mold opening of the composite template used in the decorative gypsum board production line is installed on the top of the protective frame 107. When mold opening is required, the control unit sends a signal to the power component, and the power component begins to operate. Taking the electric telescopic rod 105 as an example, after receiving the control signal, the movable part of the electric telescopic rod 105 begins to extend or retract the push rod. The movable part of the electric telescopic rod 105 is connected to the support plate 2. When the electric telescopic rod 105 is opened, the telescopic part of the electric telescopic rod 105 extends, and the mold 204 extrudes the composite template used in the decorative gypsum board production line into the slot 3.

[0028] Multiple buffer springs 201 are connected to the bottom of the support plate 2. A connecting plate 203 is connected to the end of the buffer springs 201 away from the support plate 2. A second guide post 202 is welded to the top of the connecting plate 203. A mold 204 for forming composite templates for decorative gypsum board production line is installed at the bottom of the connecting plate 203. The composite template for decorative gypsum board production line is placed flat between the mold 204 and the slot 3. A first guide post 106 is welded to the top of the support plate 2.

[0029] Welding strips 6 are welded to the vertical inner wall of the support platform 1. Multiple limiting rings 601 are connected to the top of the welding strips 6 for fixing. The limiting rings 601 prevent the rotating shaft 501 from shifting. A switch 101, a control panel 102, and a sealing plate 103 are installed on the side of the support platform 1. The control panel 102 is used to control the power source's start, stop, speed adjustment, and stroke control functions. It generally includes a controller (such as a PLC - Programmable Logic Controller), sensors (position sensor 403, pressure sensor), and related electrical components (such as relays, contactors, etc.). The control panel 102 receives signals from the sensors, such as the mold's opening and closing position and the power source's pressure, to precisely control the power source. For example, the position sensor 403 can monitor the mold opening stroke in real time. When the preset mold opening position is reached, the position sensor 403 sends a signal to stop the power source, thereby achieving precise mold opening operation.

[0030] Working principle

[0031] The decorative gypsum board production line uses an automatic mold opening device for composite templates. In use, the composite template is first placed flat between the mold 204 and the slot 3. The electric telescopic rod 105 is activated, extending its telescopic portion. The mold 204 compresses the composite template into the slot 3, which in turn compresses the buffer plate 301 and the sliding column 402. The sliding column 402 compresses the compression spring 401, ultimately shaping the composite template. The movable portion of the electric telescopic rod 105 then shortens, and the motor 5 is activated. The motor 5 drives the rotating shaft 501 and the cam 502 to rotate. The cam 502 continuously contacts the corrugated block 503. Because the corrugated block 503 is corrugated, the slot 3 vibrates, creating a gap between the composite template and the slot 3. When it is necessary to remove the composite template, the base plate 307 can be removed from the sealing plate 103.
