Description
Technical Field
[0001] This utility model relates to the technical field of production equipment for magnesium oxide fireproof boards, and more specifically, to a high-performance demolding machine for magnesium oxide fireproof boards. Background Technology
[0002] Magnesium oxide fireproof boards are widely used in construction and decoration due to their excellent fire resistance, mechanical strength and environmental protection characteristics. In the production process, mold forming is a key link, and demolding, as an important process after forming, directly affects the production efficiency and quality of the product.
[0003] However, existing molds for magnesium oxide fireproof boards often require manual assistance or use relatively simple ejection structures during demolding, resulting in low demolding efficiency and difficulty in meeting the needs of large-scale production. Furthermore, due to unreasonable demolding structure design, uneven stress is prone to occur, causing damage and deformation of the magnesium oxide fireproof board during demolding, affecting product quality. In addition, the lack of effective auxiliary demolding design makes the demolding operation complicated, increasing the labor intensity of workers and production costs.
[0004] Therefore, we have made improvements and proposed a high-performance demolding machine for magnesium oxide fireproof boards. Utility Model Content
[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a steam curing device for manufactured sand concrete, thereby solving the problems mentioned in the background. This invention utilizes an automated structure with an upper mold pressing and linkage demolding mechanism, combining the pressing of the upper mold with the downward movement of the piston plate in the mold cavity. Demolding preparation is completed simultaneously during the pressing process, eliminating the need for an additional power source. During demolding, the spring elastic reset drives the piston plate in the mold cavity to move upward and eject the finished product. This improves upon the inefficiency caused by traditional demolding machines relying on manual labor or complex power systems, achieving a continuous automated process for pressing and demolding, and improving the production efficiency of magnesium oxide fireproof boards.
[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0007] A high-performance demolding machine for magnesium oxide fireproof boards includes a base plate, a lower mold mounted on the upper side of the base plate, a mold cavity on the upper side of the lower mold, two mounting grooves on the lower side of the inner wall of the mold cavity, two extrusion plates slidably fitted on the upper side of the lower mold, two inclined grooves symmetrically arranged on one side of each extrusion plate, connecting seats slidably fitted on both sides of each extrusion plate, and L-shaped rods fixedly connected to opposite sides of each of the two connecting seats. Demolding mechanisms are provided inside each of the two mounting grooves. An upper mold is mounted on the upper side of the lower mold to mate with it, and a punch that mates with the mold cavity is mounted on the lower side of the upper mold.
[0008] Furthermore, the connecting seat is slidably fitted onto the inner wall of the inclined groove.
[0009] Furthermore, the demolding mechanism includes a slide rod fixedly connected to the inner wall of the mounting groove, two slide seats slidably fitted on the slide rod, springs sleeved at both ends of the slide rod, a mold cavity piston plate slidably fitted on the inner wall of the mold cavity, and a connecting rod between the two slide seats and the mold cavity piston plate.
[0010] Furthermore, the two ends of the spring are fixedly connected to the inner wall of the mounting groove and one side of the slide, respectively. The slide is fixedly connected to one side of the L-shaped rod, and the two ends of the connecting rod are rotatably engaged with the slide and the mold cavity piston plate, respectively.
[0011] Furthermore, a U-shaped frame is fixedly connected to the upper side of the base plate, and two hydraulic cylinders are installed on the upper side of the U-shaped frame. The output ends of the two hydraulic cylinders are fixedly connected to the upper side of the upper mold.
[0012] Furthermore, a limiting groove is formed on one side of the inner wall of the mounting groove, and a slider that slides in cooperation with the inner wall of the limiting groove is fixedly connected to one side of the L-shaped rod.
[0013] Furthermore, a cooling pipe is installed on the lower side of the inner wall of the mold cavity, and a plurality of heat-conducting plates that cooperate with the lower side of the piston plate of the mold cavity are fixedly connected to the upper side of the cooling pipe.
[0014] Furthermore, the upper side of the lower mold is fixedly connected with multiple trapezoidal blocks, and the lower side of the upper mold is provided with multiple trapezoidal grooves that cooperate with the trapezoidal blocks.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. This utility model, by setting an automated structure of upper mold pressing linkage demolding mechanism, combines the pressing of the upper mold with the downward movement of the mold cavity piston plate. During the pressing process, demolding preparation is completed simultaneously without the need for an additional power source.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] Please refer to Figure 1-5 A high-performance demolding machine for magnesium oxide fireproof boards includes a base plate 1. A lower mold 2 is mounted on the upper side of the base plate 1. A mold cavity 3 is opened on the upper side of the lower mold 2. Two mounting grooves 4 are opened on the lower side of the inner wall of the mold cavity 3. Two extrusion plates 5 are slidably fitted on the upper side of the lower mold 2. Two inclined grooves 6 are symmetrically arranged on one side of the extrusion plates 5. Connecting seats 7 are slidably fitted on both sides of the extrusion plates 5. L-shaped rods 8 are fixedly connected to the opposite sides of the two connecting seats 7. Demolding mechanisms 9 are arranged inside the two mounting grooves 4. An upper mold 10 is mounted on the upper side of the lower mold 2 and cooperates with it. A punch 11 that cooperates with the mold cavity 3 is mounted on the lower side of the upper mold 10. The connecting seats 7 are slidably fitted on the inner wall of the inclined grooves 6. Through the ingenious cooperation of components such as the inclined grooves 6, connecting seats 7, and L-shaped rods 8, the vertical movement of the upper mold 10 is converted into the horizontal and vertical movement of the demolding mechanism 9, resulting in a compact structural layout.
[0027] Specifically, when the high-performance demolding machine for magnesium oxide fireproof board is running, the raw material of magnesium oxide fireproof board is first placed in the mold cavity 3 of the lower mold 2. Then, the two hydraulic cylinders 13 located on the upper side of the U-shaped frame 12 are activated. The output end of the hydraulic cylinder 13 pushes the upper mold 10 downward, so that the punch 11 on the lower side of the upper mold 10 is pressed into the mold cavity 3, and cooperates with the lower mold 2 to complete the pressing work of the raw material. During the pressing process, the cooling pipe 16 and the heat conduction plate 17 work together to cool the raw material in the mold cavity 3 and accelerate the molding of the magnesium oxide fireproof board.
[0028] In this embodiment, the demolding mechanism 9 includes a slide rod 91 fixedly connected to the inner wall of the mounting groove 4. Two slide seats 92 are slidably fitted on the slide rod 91. Springs 93 are sleeved on both ends of the slide rod 91. A mold cavity piston plate 94 is slidably fitted on the inner wall of the mold cavity 3. A connecting rod 95 is provided between the two slide seats 92 and the mold cavity piston plate 94. The two ends of the springs 93 are fixedly connected to the inner wall of the mounting groove 4 and one side of the slide seats 92, respectively. The slide seats 92 are fixedly connected to one side of the L-shaped rod 8. The two ends of the connecting rod 95 are rotatably fitted to the slide seats 92 and the mold cavity piston plate 94, respectively. A cooling pipe 16 is installed on the lower side of the inner wall of the mold cavity 3. Multiple heat-conducting plates 17 that cooperate with the lower side of the mold cavity piston plate 94 are fixedly connected to the upper side of the cooling pipe 16. By combining the downward pressing of the upper mold 10 with the pre-action of the demolding mechanism 9, the piston plate 94 of the mold cavity is moved downward during the downward pressing process of the upper mold 10, without the need for an additional power source, thus reducing energy consumption; during demolding, the spring 93 automatically drives the demolding, forming a continuous automated workflow and improving production efficiency.
[0029] Specifically, when the upper mold 10 moves downward, its bottom will press down on the extrusion plate 5. After being subjected to pressure, the extrusion plate 5 slides on the upper side of the lower mold 2. Since the connecting seat 7 is slidably fitted on the inner wall of the inclined groove 6 of the extrusion plate 5, when the extrusion plate 5 slides, the inclined surface of the inclined groove 6 will generate a lateral extrusion force on the connecting seat 7, pushing the connecting seat 7 to move outward. The connecting seat 7 drives the L-shaped rod 8 to move synchronously. When the L-shaped rod 8 moves, it pulls the slide block 92 to slide on the slide rod 91, compressing the springs 93 at both ends of the slide rod 91. At the same time, the slide block 92 drives the mold cavity piston plate 94 downward through the connecting rod 95 on the inner wall of the mold cavity 3. During the sliding process, the piston plate 94 of the mold cavity moves downward to reserve space for the pressing of raw materials and plays a stabilizing support role during the pressing process. After the glass magnesium fireproof board is pressed, the hydraulic cylinder 13 drives the upper mold 10 to move upward and reset. As the upper mold 10 moves upward, it no longer applies pressure to the extrusion plate 5. The compressed spring 93 begins to release its elastic potential energy, pushing the slide block 92 to slide in the opposite direction on the slide rod 91. The slide block 92 is driven by the connecting rod 95 to drive the piston plate 94 of the mold cavity 3 to slide upward on the inner wall of the mold cavity 3, pushing the formed glass magnesium fireproof board out of the mold cavity 3, thereby completing the demolding operation.
[0030] In this embodiment, a U-shaped frame 12 is fixedly connected to the upper side of the base plate 1. Two hydraulic cylinders 13 are mounted on the upper side of the U-shaped frame 12, and the output ends of the two hydraulic cylinders 13 are fixedly connected to the upper side of the upper mold 10. A limiting groove 14 is formed on one side of the inner wall of the mounting groove 4, and a slider 15 that slides and engages with the inner wall of the limiting groove 14 is fixedly connected to one side of the L-shaped rod 8. Multiple trapezoidal blocks 18 are fixedly connected to the upper side of the lower mold 2, and multiple trapezoidal grooves 19 that engage with the trapezoidal blocks 18 are formed on the lower side of the upper mold 10. The engagement of the L-shaped rod 8 with the limiting groove 14 and the slider 92 with the slide rod 91 provides stable guidance for the operation of the mechanism, avoids shaking during the movement, and ensures long-term reliable operation of the equipment.
[0031] Specifically, the slider 15 on the L-shaped rod 8 slides within the limiting groove 14 to ensure the stability and guidance of the movement of the L-shaped rod 8. The trapezoidal block 18 and the trapezoidal groove 19 cooperate with each other to improve the accuracy of mold closing and improve the production and molding effect of the glass fireproof board.
