Description

Technical Field

[0001] This utility model relates to the field of silicon carbide mold technology, specifically a mold for the production of silicon carbide bricks with rapid demolding. Background Technology

[0002] Molds used for producing silicon carbide bricks typically consist of a base plate, side plates, and a mold core. The base plate is the foundation of the mold. The side plates are installed around the base plate to determine the shape and size of the brick. The mold core is designed according to the specific shape and structure of the brick and can be installed in the center of the base plate or other locations. Silicon carbide raw material is filled into the mold cavity formed by the base plate, side plates, and mold core. Then, pressure is applied by a press to shape the raw material within the mold. This method is suitable for producing silicon carbide bricks with relatively regular shapes and large sizes, such as standard silicon carbide bricks and some irregularly shaped silicon carbide bricks.

[0003] For example, the Chinese authorized patent CN217531198U, entitled "A Mold for Lightweight Brick Production," includes a fixed base. A lower mold is movably mounted on the top of the fixed base, and connecting drive mechanisms fixedly connected to the lower mold are fixedly mounted on both the left and right sides of the top of the fixed base. This lightweight brick production mold, by setting an electric slide, first places the upper mold on top of the lower mold, allowing the auxiliary plate to enter the mold cavity. Then, lightweight brick material is injected into the mold cavity inside the lower mold through an injection pipe. After the lightweight brick material is formed, the electric slide inside the fixed plate moves, driving a slider to move, which in turn moves the lower mold. The movement of the lower mold causes the formed lightweight brick inside the mold cavity to fall onto a fixed block, achieving convenient demolding.

[0004] While the existing technologies mentioned above can achieve demolding of bricks, they still require manual intervention, which has limited effect on improving the production efficiency of silicon carbide bricks. Moreover, when applied to large-scale mass production, it is difficult to arrange the demolded silicon carbide bricks in an orderly manner, thus failing to meet current needs. In response, we propose a mold for the production of silicon carbide bricks that allows for rapid demolding. Utility Model Content

[0005] The purpose of this invention is to provide a mold for the production of silicon carbide bricks that allows for rapid demolding, in order to solve the problems of poor demolding effect and low automation of silicon carbide brick molds mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mold for producing silicon carbide bricks with rapid demolding, comprising a base, a molding cavity provided at the middle position of the upper surface of the base, a demolding seat slidably limited inside the molding cavity, a lifting and adjusting mechanism provided at the bottom of the demolding seat for moving the pressed silicon carbide bricks above the base, a hollow groove provided inside the demolding seat, a slot provided at the lower end of one side of the molding cavity, a limiting groove provided at the lower end of the other side of the molding cavity, a reinforcing plate slidably limited inside the limiting groove, and the reinforcing plate extends through the hollow groove into the slot, a reinforcing plate displacement transmission assembly provided below the limiting groove, a silicon carbide brick pushing mechanism provided on one side of the upper surface of the base, and a feeding mechanism provided on the other side of the upper surface of the base.

[0007] Preferably, the lifting adjustment mechanism includes a lifting column fixedly installed at the bottom of the demolding base, and the lifting column is slidably limited to the inner cavity of the base. A stud is rotatably installed in the inner cavity of the base, the stud extends into the interior of the lifting column, and the stud is threadedly connected to the lifting column. A servo motor for driving the stud to rotate is provided at the lower end of the inner cavity of the base.

[0008] Preferably, the displacement transmission assembly includes a transmission gear and a rack. The transmission gear is rotatably connected to the base and is driven to rotate by a motor built into the base. The rack is disposed on one side of the bottom of the reinforcing plate and is meshed with the transmission gear.

[0009] Preferably, the silicon carbide brick pushing mechanism includes a hydraulic lifting device fixedly installed on one side of the upper end face of the base, and the movable end of the hydraulic lifting device is equipped with a top plate, which is located on one side above the molding cavity.

[0010] Preferably, the feeding mechanism includes a frame fixedly installed on the other side of the upper end of the base, two rotating transmission rollers are symmetrically installed inside the frame, a feeding belt is installed outside the transmission rollers, and a feeding motor for driving the transmission rollers to rotate is installed at the front end of one side of the frame.

[0011] Preferably, the discharge end of the feeding mechanism extends to the outside of the base.

[0012] Preferably, guide support columns are fixedly installed at the four corners of the upper surface of the base, and a forming mold that slides and limits the guide support columns is installed between them. A top plate is fixedly installed at the top of the guide support columns, and a hydraulic lifting device is installed at the upper end of the top plate. The movable end of the hydraulic lifting device is fixed to the upper end of the forming mold.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model features an automatic demolding mechanism for silicon carbide bricks. After the silicon carbide bricks are pressed by the molding mold in the molding cavity, as the molding mold rises, the locking and reinforcing mechanism releases the demolding seat, the servo motor starts, and its output shaft drives the stud to rotate. Under the friction between the external thread of the stud and the thread of the lifting column, combined with the guiding effect of the inner cavity of the base on the lifting column, the lifting column drives the demolding seat to move upward, thereby pushing the pressed silicon carbide bricks out of the base. This ensures a stable and precise demolding process, avoids damage to the silicon carbide bricks caused by improper manual operation, realizes automated demolding, greatly reduces manual intervention, reduces labor intensity, and improves production efficiency.

[0015] 2. This utility model, by providing a locking and reinforcing mechanism, when the next silicon carbide brick needs to be pressed, the lifting column, driven by the servo motor, causes the demolding seat to return to the molding cavity. At this time, the motor at one end of the transmission gear is turned on, driving the transmission gear to rotate. Under the meshing of the transmission gear and the rack at the bottom of the reinforcing plate, the rotational motion is converted into linear motion, driving the reinforcing plate through the hollow groove inside the demolding seat and fixing it with the slot on the base, thus achieving strong support for the demolding seat. This effectively resists the huge pressure generated during the pressing of the molding mold, avoids the demolding seat from shifting, shaking, or even being damaged, and ensures that the silicon carbide brick is dimensionally accurate and has a regular shape during pressing.

[0016] 3. This utility model features a pushing mechanism. After the pressed silicon carbide bricks are ejected, the electric push rod is activated, causing the push plate at the movable end to push the silicon carbide bricks towards the feeding mechanism until they fall onto the feeding belt of the feeding mechanism. At this time, the feeding motor remains running, and with the cooperation of the two transmission rollers, the feeding belt moves the silicon carbide bricks. This achieves automated connection of the silicon carbide bricks from demolding to conveying. The combination of the electric push rod and the push plate can quickly and accurately push the demolded bricks onto the feeding belt, ensuring that the bricks are delivered to the next process in a timely manner, reducing the production stagnation caused by material accumulation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 An embodiment of this utility model provides a mold for producing silicon carbide bricks with rapid demolding, including a base 1, a molding cavity 2 provided at the middle position of the upper end face of the base 1, a demolding seat 13 provided inside the molding cavity 2 for sliding and limiting, a lifting and adjusting mechanism provided at the bottom of the demolding seat 13 for moving the pressed silicon carbide bricks above the base 1, a hollow groove 14 provided inside the demolding seat 13, a slot 15 provided at the lower end of one side of the molding cavity 2, a limiting groove 16 provided at the lower end of the other side of the molding cavity 2, a reinforcing plate 20 provided inside the limiting groove 16 for sliding and limiting, and the reinforcing plate 20 extends through the hollow groove 14 to the inside of the slot 15, a displacement transmission component for the reinforcing plate 20 provided below the limiting groove 16, a silicon carbide brick pushing mechanism provided on one side of the upper end face of the base 1, and a feeding mechanism 5 provided on the other side of the upper end face of the base 1;

[0024] During the molding process of silicon carbide bricks, the lifting and adjusting mechanism first places the demolding seat 13 at a suitable position at the bottom of the molding cavity 2, and the raw material is pressed in the space formed by the molding mold 10 and the demolding seat 13. After molding, the lifting and adjusting mechanism is activated to move the demolding seat 13 along with the silicon carbide bricks to the top of the base 1. Then, the displacement transmission component of the reinforcing plate 20 operates, so that the reinforcing plate 20 passes through the empty groove 14 of the demolding seat 13 and inserts into the slot 15 to fix the demolding seat 13, and then the next pressing is performed. After the pressing is completed and the bricks are demolded again, the silicon carbide brick pushing mechanism pushes the bricks to the feeding mechanism 5, and the feeding belt 7 of the feeding mechanism 5 transports the bricks to the outside of the base 1.

[0025] Please see Figure 2 The lifting adjustment mechanism includes a lifting column 17 fixedly installed at the bottom of the demolding base 13, and the lifting column 17 slides and limits the inner cavity of the base 1. A stud 19 is rotatably installed in the inner cavity of the base 1. The stud 19 extends into the interior of the lifting column 17 and is threadedly connected to the lifting column 17. A servo motor 18 for driving the stud 19 to rotate is provided at the lower end of the inner cavity of the base 1.

[0026] After the silicon carbide brick is pressed in the molding cavity 2, the servo motor 18 is turned on, and its output shaft drives the stud 19 to rotate. Since the stud 19 is threadedly connected to the lifting column 17, and the inner cavity of the base 1 guides the lifting column 17, the rotational motion of the stud 19 is converted into the linear motion of the lifting column 17 under the friction of the threads, which in turn drives the demolding seat 13 to move upward, pushing the pressed silicon carbide brick out of the base 1. When it is necessary to press the next silicon carbide brick, the servo motor 18 rotates in the opposite direction, so that the lifting column 17 drives the demolding seat 13 to return to the molding cavity 2.

[0027] Please see Figure 4 The displacement transmission assembly includes a transmission gear 21 and a rack 22. The transmission gear 21 is rotatably connected to the base 1 and is driven to rotate by a motor built into the base 1. The rack 22 is located on one side of the bottom of the reinforcing plate 20 and is meshed with the transmission gear 21.

[0028] After the lifting and adjusting mechanism resets the demolding seat 13 into the molding cavity 2, the motor built into the base 1 starts, driving the transmission gear 21 to rotate. Since the rack 22 meshes with the transmission gear 21, the rotational motion of the transmission gear 21 is converted into the linear motion of the rack 22 through meshing transmission. The rack 22 is fixed to the bottom of the reinforcing plate 20, thereby driving the reinforcing plate 20 to slide in the limiting slide groove 16, so that it passes through the empty groove 14 inside the demolding seat 13 and is fixed to the slot 15 on the base 1, thus achieving strong support for the demolding seat 13. When demolding is required, the motor rotates in the opposite direction, and the transmission gear 21 drives the rack 22 to disengage the reinforcing plate 20 from the slot 15, releasing the lock on the demolding seat 13. The displacement transmission component, through the meshing transmission of the gear and rack, can quickly and stably realize the extension and retraction of the reinforcing plate 20, and accurately lock and unlock the demolding seat 13. During the pressing process, it provides reliable support for the demolding seat 13, preventing the demolding seat 13 from shifting or deforming due to excessive pressure, thus ensuring the molding accuracy of silicon carbide bricks; and it can also release the restriction in time during demolding without affecting the demolding process.

[0029] Please see Figure 1 and Figure 3 The silicon carbide brick pushing mechanism includes a hydraulic lifting device 12 fixedly installed on one side of the upper end face of the base 1. The movable end of the hydraulic lifting device 12 is equipped with a top plate 11, and the top plate 11 is located on one side above the molding cavity 2. When the lifting adjustment mechanism pushes the pressed silicon carbide brick out of the base 1, the hydraulic lifting device 12 is activated, and its movable end drives the top plate 11 to descend until the top plate 11 contacts the silicon carbide brick. Then the hydraulic lifting device 12 continues to operate, pushing the top plate 11 to push the silicon carbide brick towards the feeding mechanism 5. When the silicon carbide brick is pushed onto the feeding belt 7 of the feeding mechanism 5, the hydraulic lifting device 12 drives the top plate 11 to reset.

[0030] Please see Figure 1 and Figure 2 The feeding mechanism 5 includes a frame 6 fixedly installed on the other side of the upper end of the base 1. Two rotating transmission rollers are symmetrically installed inside the frame 6. A feeding belt 7 is installed outside the transmission rollers. A feeding motor 8 that drives the transmission rollers to rotate is installed at the front end of one side of the frame 6. The discharge end of the feeding mechanism 5 extends to the outside of the base 1. The feeding motor 8 is continuously turned on, and its output shaft drives the transmission rollers to rotate. Since the feeding belt 7 is sleeved outside the two transmission rollers, it starts to run under the friction of the transmission rollers. When the silicon carbide brick is pushed onto the feeding belt 7 by the silicon carbide brick pushing mechanism, the movement of the feeding belt 7 transports the brick to the outside of the base 1, completing the feeding process.

[0031] Please see Figure 1 Guide support columns 9 are fixedly installed at the four corners of the upper surface of the base 1. A forming mold 10 is installed between the guide support columns 9 and is slidably limited thereto. A top plate 11 is fixedly installed at the top of the guide support columns 9. A hydraulic lifting device 12 is installed at the upper end of the top plate 11, and the movable end of the hydraulic lifting device 12 is fixed to the upper end of the forming mold 10.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
