Description

Technical Field

[0001] This utility model relates to the technical field of refractory material production, and in particular to a refractory material pressing device. Background Technology

[0002] Forming and processing equipment for pressing refractory materials is an essential part of the refractory material manufacturing process. It is mainly used to press raw materials into plates or blocks for easy processing. Chinese utility model patent CN221291719U discloses a refractory material pressing device. This device includes a mold assembly and a pressing assembly mounted on a frame. The mold assembly includes a fixed base at the bottom of the frame, an assembly groove on the top surface of the fixed base, a hydraulic telescopic column at the bottom of the assembly groove, a support plate connected to the upper end of the hydraulic telescopic column, and a mold plate connected to the support plate via several support springs. The pressing assembly includes a mounting plate at the top of the frame, a drive cylinder on the top surface of the mounting plate, a counterweight connected to the drive cylinder via a piston rod, an upper pressing head connected to the bottom surface of the counterweight, and a sliding collar slidably connected to the outer periphery of the upper pressing head. A dust cover is mounted on the bottom surface of the sliding collar. During the descent of the upper pressing head into the mold cavity, the bottom surface of the dust cover first contacts the top surface of the assembly plate, achieving complete coverage of the mold cavity. This effectively prevents the refractory material from being squeezed out and splashing the moment the upper pressing head enters the mold cavity, providing a certain level of protection and enhancing safety.

[0003] The existing pressing device has a lower pressing component and an upper mold that move up and down above the lower mold. Due to the obstruction of the lower pressing component and the upper mold, it will cause obstacles when picking up and putting down the raw materials and the formed refractory materials, which is not conducive to improving work efficiency. Moreover, the lower pressing component and the upper mold are at risk of falling and injuring the workers. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a refractory material pressing device that adopts an upper mold that opens and closes to the side, avoiding obstruction of refractory material loading and unloading, and has high working efficiency and good safety.

[0005] This utility model discloses a refractory material pressing device, comprising a platform, a main pusher cylinder, and a lower mold. The fixed end of the main pusher cylinder is mounted on the platform, and the lower mold is mounted on the top of the piston rod of the main pusher cylinder. It also includes multiple vertical shafts, hinged columns, a horizontal rod, an upper pressure plate, an upper mold, and an auxiliary pusher cylinder. The multiple vertical shafts are vertically mounted on the platform. The lower mold is slidably connected to the multiple vertical shafts via sliding sleeves. The hinged columns are vertically mounted on the side of the platform. The middle part of the horizontal rod is hinged to the top of the hinged columns. The upper pressure plate is mounted on the inner end of the horizontal rod, and the upper mold is mounted on the lower end face of the upper pressure plate. The upper pressure plate and the upper mold are located above the lower mold, and the upper mold can extend into the cavity of the lower mold. The lower end of the auxiliary pusher cylinder is hinged to the platform, and the upper end of the piston rod of the auxiliary pusher cylinder is hinged to the outer end of the horizontal rod. During operation, the piston rod of the auxiliary pusher cylinder retracts, pulling the outer end of the horizontal rod downwards, thereby causing the inner end of the horizontal rod to lift the upper pressure plate upwards, causing the upper pressure plate and the upper mold to flip and tilt to the outside of the lower mold. The piston of the main pusher cylinder... The rod retracts, causing the lower mold to descend along the vertical axis to its lowest position. The refractory material raw material is then placed into the cavity of the lower mold according to the process. The piston rod of the auxiliary pusher cylinder extends, pushing the outer end of the crossbar upwards. This causes the inner end of the crossbar to flip the upper pressure plate downwards and flatten it, allowing the upper pressure plate to move the upper mold above the cavity of the lower mold. The piston rod of the main pusher cylinder extends upwards, pushing the lower mold upwards, causing the upper mold to extend into the cavity of the lower mold and press the raw material into refractory bricks or plates. After pressing, the piston rod of the main pusher cylinder retracts, causing the lower mold to descend. The piston rod of the auxiliary pusher cylinder retracts, causing the upper pressure plate to flip the upper mold to the outside of the lower mold, removing the formed refractory material from the cavity of the lower mold. Compared to existing technologies, when handling refractory material raw materials and formed bricks or plates, the flipping of the upper pressure plate and upper mold to the outside of the lower mold does not cause obstruction, improving work efficiency and reducing the risk of falling materials injuring workers, thus ensuring good safety.

[0006] Preferably, it also includes multiple thrust bearing seats and multiple pressure plates. The multiple thrust bearing seats are respectively mounted on multiple vertical shafts, and the multiple pressure plates are respectively installed on the rotating ends of the multiple thrust bearing seats. The edge of the upper pressure plate is provided with multiple clearance openings for avoiding the pressure plates. The multiple pressure plates are rotatably mounted on the multiple vertical shafts through the multiple thrust bearing seats. When the upper pressure plate is placed flat above the lower mold, the multiple pressure plates reach the upper end surface of the upper pressure plate through the multiple clearance openings of the upper pressure plate. Rotating the multiple pressure plates causes them to press against the upper end of the upper pressure plate, thereby limiting the upper end surface of the upper pressure plate and improving the stability of the lower mold in pressing the refractory material with the upper mold.

[0007] Preferably, the device further includes multiple drive wheels and a drive belt. The multiple drive wheels are concentrically mounted on the rotating ends of multiple thrust bearing seats, and are located below multiple pressure plates. The drive belt is sleeved and connected to the multiple drive wheels. The drive belt enables the multiple drive wheels to drive synchronously, so that when one pressure plate is rotated, the pressure plate drives the drive wheel below it to rotate through the rotating end of the thrust bearing seat. This drive wheel drives the other multiple drive wheels to rotate synchronously through the drive belt, thereby enabling the multiple pressure plates to rotate synchronously and achieving synchronous operation of multiple pressure plates, thus improving work efficiency.

[0008] Preferably, it also includes a motor and a drive wheel. The motor is mounted on the hinged column via a bracket, and the drive wheel is concentrically mounted on the output shaft of the motor. The drive wheel is connected to a transmission belt. The transmission belt is fitted onto the drive wheel, so that when the motor drives the drive wheel to rotate, it drives the transmission belt to rotate. The transmission belt drives multiple transmission wheels to rotate synchronously, thereby causing multiple pressure plates to rotate synchronously and automatically, pressing and releasing the upper pressure plate.

[0009] Preferably, it also includes multiple clamping rollers, which are rotatably mounted on the hinged column and platform via a bracket. The multiple clamping rollers tension and press the transmission belt against the drive wheel and multiple transmission wheels. By setting multiple clamping rollers, the wrap angle between the transmission belt and the multiple transmission wheels and drive wheels meets the transmission requirements, thereby improving the reliability and stability of the transmission.

[0010] Preferably, the assembly also includes an inner push plate, multiple sliding rods, and multiple springs. The inner push plate is vertically and slidably installed in the cavity of the lower mold. The upper ends of the multiple sliding rods pass through the bottom of the cavity of the lower mold and connect to the inner push plate. The lower ends of the sliding rods are slidably inserted into the main push cylinder. One end of each of the multiple springs is connected to one of the sliding rods, and the other end of each spring is connected to the platform. When the piston rod of the main push cylinder extends and pushes the lower mold to rise and press the refractory material raw material, the bottom of the cavity of the lower mold drives the inner push plate to rise, so that the inner push plate and the cavity of the lower mold are pressed and formed. During the process, the inner push plate drives multiple sliding rods to rise and stretches multiple springs to store energy. After the refractory material is pressed into shape, the piston rod of the main push cylinder retracts and pulls the lower mold down. The elastic force of multiple springs is released and drives the inner push plate to descend synchronously through multiple sliding rods. After the multiple springs retract and reset, the multiple springs begin to support the multiple sliding rods and the inner push plate with their elastic force, thereby causing the inner push plate to push out the refractory material pressed into shape in the cavity of the lower mold, achieving rapid material discharge. Setting limit blocks on multiple sliding rods can improve the pushing effect of multiple inner push plates on the formed refractory material.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: when taking and placing raw materials and molded bricks or plates of refractory materials, the upper pressure plate and the upper mold flip to the outside of the lower mold, which will not cause obstruction, which is conducive to improving work efficiency and reducing the risk of falling and injuring workers, thus ensuring good safety.

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, a refractory material pressing device includes a platform 1, a main push cylinder 2, and a lower mold 3. The fixed end of the main push cylinder 2 is mounted on the platform 1, and the lower mold 3 is mounted on the top of the piston rod of the main push cylinder 2. It also includes multiple vertical shafts 4, hinged columns 5, a horizontal bar 6, an upper pressure plate 7, an upper mold 8, and an auxiliary push cylinder 9. The multiple vertical shafts 4 are vertically mounted on the platform 1. The lower mold 3 is slidably connected to the multiple vertical shafts 4 via sliding sleeves. The hinged columns 5 are vertically mounted on the side of the platform 1. The middle part of the horizontal bar 6 is hinged to the top of the hinged column 5. The upper pressure plate 7 is mounted on the inner end of the horizontal bar 6. The upper mold 8 is mounted on the lower end face of the upper pressure plate 7. The upper pressure plate 7 and the upper mold 8 are located above the lower mold 3. The upper mold 8 can extend into the cavity of the lower mold 3. The lower end of the auxiliary push cylinder 9 is hinged to the platform 1, and the upper end of the piston rod of the auxiliary push cylinder 9 is hinged to the outer end of the horizontal bar 6. It also includes multiple thrust bearing seats 10 and multiple pressure plates 11. The seats 10 are respectively mounted on multiple vertical shafts 4, and multiple pressure plates 11 are respectively installed on the rotating ends of multiple thrust bearing seats 10. The edge of the upper pressure plate 7 is provided with multiple clearance openings for avoiding the pressure plates 11. It also includes multiple transmission wheels 12 and transmission belts 13. The multiple transmission wheels 12 are respectively concentrically installed on the rotating ends of multiple thrust bearing seats 10 and are respectively located below multiple pressure plates 11. The transmission belts 13 are mounted on the multiple transmission wheels 12. It also includes a motor 14 and a drive wheel 15. The motor 14 is mounted on the hinge column 5 through a bracket. The output shaft of the motor 14 is concentrically mounted on the drive wheel 15. The drive wheel 15 is connected to the transmission belt 13. It also includes multiple clamping wheels 16. The multiple clamping wheels 16 are rotatably mounted on the hinge column 5 and the platform 1 through a bracket. The multiple clamping wheels 16 tension and press the transmission belt 13 onto the drive wheel 15 and the multiple transmission wheels 12.

[0021] Multiple pressure plates 11 are rotatably mounted on multiple vertical shafts 4 via multiple thrust bearing seats 10. During operation, the piston rod of the auxiliary push cylinder 9 retracts, pulling the outer end of the crossbar 6 downwards, thereby causing the inner end of the crossbar 6 to lift the upper pressure plate 7 upwards, causing the upper pressure plate 7 and the upper mold 8 to flip and tilt to the outside of the lower mold 3. The piston rod of the main push cylinder 2 retracts, causing the lower mold 3 to descend to its lowest position along the vertical shaft 4, and the refractory material raw material is placed into the cavity of the lower mold 3 according to the process. The piston rod of the auxiliary push cylinder 9 extends, pushing the outer end of the crossbar 6 upwards, causing the inner end of the crossbar 6 to flip the upper pressure plate 7 downwards and flatten it, so that the upper pressure plate 7 drives the upper mold 8 to reach the upper cavity of the lower mold 3. Multiple pressure plates 11 reach the upper surface of the upper pressure plate 7 through multiple clearance openings of the upper pressure plate 7. When the motor 14 drives the drive wheel 15 to rotate, it drives the transmission belt 13 to rotate. The transmission belt 13 drives multiple transmission wheels 12 to rotate synchronously. 2. The main push cylinder 2 drives multiple pressure plates 11 to rotate synchronously, so that the multiple pressure plates 11 press against the upper end of the upper pressure plate 7, thereby limiting the upper end face of the upper pressure plate 7 and improving the stability of the lower mold 3 in conjunction with the upper mold 8 in pressing refractory materials. The piston rod of the main push cylinder 2 extends upward, pushing the lower mold 3 upward, so that the upper mold 8 extends into the cavity of the lower mold 3 to press the raw material into refractory bricks or plates. After pressing, the piston rod of the main push cylinder 2 retracts, causing the lower mold 3 to descend. The piston rod of the auxiliary push cylinder 9 retracts, causing the upper pressure plate 7 to rotate the upper mold 8 to the outside of the lower mold 3, and the formed refractory material is taken out from the cavity of the lower mold 3. Compared with the existing technology, when taking out and putting in the raw material of refractory materials and the formed bricks or plates, the upper pressure plate 7 and the upper mold 8 rotate to the outside of the lower mold 3, which will not cause obstruction, which will help improve work efficiency and reduce the risk of falling and injuring workers, thus improving safety. Example 2

[0022] like Figure 2 , Figure 4 and Figure 5As shown, based on Embodiment 1, it also includes an inner push plate 17, multiple slide rods 18, and multiple springs 19. The inner push plate 17 is slidably installed in the cavity of the lower mold 3. The upper ends of the multiple slide rods 18 pass through the bottom of the cavity of the lower mold 3 and are connected to the inner push plate 17. The lower ends of the slide rods 18 are slidably inserted into the main push cylinder 2. One end of each of the multiple springs 19 is connected to the multiple slide rods 18, and the other end of each spring 19 is connected to the platform 1. When the piston rod of the main push cylinder 2 extends and pushes the lower mold 3 to rise and press the refractory material raw material, the bottom of the cavity of the lower mold 3 drives the inner push plate 17 to rise, so that the inner push plate 17 presses against the cavity of the lower mold 3. During the molding process, the inner push plate 17 drives multiple slide rods 18 to rise and stretches multiple springs 19 to store force. After the refractory material is pressed and formed, the piston rod of the main push cylinder 2 retracts and pulls the lower mold 3 down. The elastic force of multiple springs 19 is released and drives the inner push plate 17 to descend synchronously through multiple slide rods 18. After multiple springs 19 retract and reset, multiple springs 19 begin to elastically support multiple slide rods 18 and inner push plate 17, thereby causing the inner push plate 17 to push out the refractory material pressed and formed in the cavity of the lower mold 3, realizing rapid material unloading. Setting limit blocks on multiple slide rods 18 can improve the pushing effect of multiple inner push plates 17 on the formed refractory material.

[0023] like Figures 1 to 6 As shown, this utility model discloses a refractory material pressing device. During operation, the piston rod of the auxiliary push cylinder 9 retracts, pulling the outer end of the crossbar 6 downwards. This causes the inner end of the crossbar 6 to lift the upper pressure plate 7 upwards, causing the upper pressure plate 7 and the upper mold 8 to flip and tilt to the outside of the lower mold 3. The piston rod of the main push cylinder 2 retracts, causing the lower mold 3 to descend along the vertical axis 4 to its lowest position. Then, the refractory material raw material is placed into the cavity of the lower mold 3 according to the process. The piston rod of the auxiliary push cylinder 9 extends, pushing the outer end of the crossbar 6 upwards, causing the inner end of the crossbar 6 to flip the upper pressure plate 7 downwards and flatten it. This causes the upper pressure plate 7 to bring the upper mold 8 to the top of the cavity of the lower mold 3. The piston rod of the main push cylinder 2 extends upwards, pushing the lower mold 3 upwards, causing the upper mold 8 to extend into the cavity of the lower mold 3 and press the raw material into refractory bricks or plates. During the pressing process, the bottom of the cavity of the lower mold 3 drives the inner push plate 17 to rise, so that the inner push plate 17 and the cavity of the lower mold 3 are pressed together. During this process, the inner push plate 17 drives multiple slide rods 18 to rise and stretches multiple springs 19 to store force. After pressing is completed, the piston rod of the main push cylinder 2 retracts and drives the lower mold 3 to fall. The piston rod of the auxiliary push cylinder 9 retracts and causes the upper pressure plate 7 to drive the upper mold 8 to flip to the outside of the lower mold 3. Finally, the piston rod of the main push cylinder 2 retracts and pulls the lower mold 3 to fall. The elastic force of multiple springs 19 is released and drives the inner push plate 17 to fall synchronously through multiple slide rods 18. When multiple springs 19 retract and reset, multiple springs 19 begin to elastically support multiple slide rods 18 and inner push plate 17, so that the inner push plate 17 pushes out the refractory material pressed in the cavity of the lower mold 3 for discharge.

[0024] The main functions achieved by this utility model are:

[0025] 1. When handling raw materials and molded bricks or slabs of refractory materials, the upper pressure plate 7 and the upper mold 8 are flipped to the outside of the lower mold 3, which will not cause obstruction and will help improve work efficiency.
