Abstract
Description
Technical Field
[0001] This utility model relates to the field of lightweight high-alumina brick production technology, specifically a molding die for producing lightweight high-alumina bricks. Background Technology
[0002] Lightweight high-alumina bricks are mainly used for lining and insulation layers of kilns and furnaces, as well as in areas without strong erosion or scouring from molten materials at high temperatures. These bricks have good thermal shock resistance and can withstand certain temperature changes without cracking. They are suitable for lining materials of various heating furnaces, coking furnaces, and other thermal equipment. High-alumina bricks require pressing and molding in a special molding die. However, existing special molding dies for high-alumina brick production generally consist of an upper die and a lower die. After molding, the push plate inside the lower die pushes the lightweight high-alumina brick upwards. This method is low-cost and easy to demold, but the upward demolding requires handling and transferring the lightweight high-alumina bricks, which is troublesome and generally not very convenient to use.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-2 This embodiment provides a technical solution: a molding die for producing lightweight high-alumina bricks, including a U-shaped base plate 1, a drive unit 1 7 and a drive unit 2 9;
[0021] U-shaped base plate 1: Sliding columns 2 are provided on both the left and right sides of its upper surface. The U-shaped base plate 1 is installed on the frame. A mold box 3 is slidably connected between the two sliding columns 2. An upper template 4 is slidably connected to the upper end of the mold box 3. The upper template 4 is connected to the pressure rod of the processing equipment. During production, the pressure rod of the processing equipment drives the upper template 4 to move upward and move out of the mold box 3. The lower end of the mold box 3 is slidably connected to the longitudinally moving lower template 5. The high alumina brick raw material is quantitatively added to the mold box 3. The lower template 5 blocks the raw material from flowing out. Then the pressure rod drives the upper template 4 to move downward to extrude and form the raw material inside the mold box 3. The mold box 3 slides upward along the sliding columns 2. The upper template 4 blocks the lightweight high alumina brick from moving upward with the mold box 3. Then the upper template 4 pushes the lightweight high alumina brick out of the mold box 3. The lightweight high alumina brick falls through the opening at the rear end of the U-shaped base plate 1 onto the conveyor belt below.
[0022] Drive unit 7: Used to drive the longitudinal movement of the lower template 5. Drive unit 7 includes a lead screw 71, which is mounted on the front side of the mold box 3 via a support base 6. The lead screw 71 is rotatably connected to the support base 6 via a bearing. The rear end of the lead screw 71 is threadedly connected to a threaded hole in the middle of the lower template 5. The lead screw 71 drives the lower template 5 to slide forward along the slide groove at the lower end of the mold box 3. Drive unit 7 also includes a motor 72, a first synchronous pulley 73, and a second synchronous pulley 74. The motor 72 is mounted on the upper surface of the support base 6, and the output shaft of the motor 72 is equipped with a first synchronous pulley. 73. The rear end of the lead screw 71 is provided with a second synchronous pulley 74. The second synchronous pulley 74 is connected to the first synchronous pulley 73 via a synchronous belt drive. The input end of the motor 72 is electrically connected to the output end of an external controller. The output shaft of the motor 72 drives the first synchronous pulley 73 to rotate. The first synchronous pulley 73 drives the lead screw 71 to rotate via the synchronous belt and the second synchronous pulley 74. The drive unit 7 also includes a protective shell 75. The protective shell 75 is located at the rear end of the support base 6. The first synchronous pulley 73 and the second synchronous pulley 74 are both located inside the protective shell 75, providing protection for the internal components.
[0023] Drive unit 2 9: Used to drive the mold box 3 to move up and down. Drive unit 2 9 includes an electric push rod 91, a connecting shaft 92, and a connecting plate 93. The electric push rod 91 is fixedly connected to the upper end of the slide column 2 through the upper support frame 8. The upper support frame 8 provides installation positions for other components. The connecting shaft 92 is provided on the telescopic end of the electric push rod 91. The connecting plates 93 are symmetrically distributed on the upper surface of the support base 6. The long sliding holes in the middle of the connecting plates 93 are all slidably connected to the connecting shaft 92. The input end of the electric push rod 91 is electrically connected to the output end of an external controller. When the telescopic end of the electric push rod 91 retracts, the telescopic end of the electric push rod 91 drives the connecting shaft 92 to move upward. Initially, the connecting shaft 92 slides relative to the long sliding holes in the middle of the connecting plate 93, and the upper end of the connecting shaft 92 contacts the long sliding holes. Then, the connecting shaft 92 drives the connecting plate 93 to move upward, and the connecting plate 93 drives the support seat 6 to move upward. The second drive unit 9 also includes a spring plate 94, which is located at the lower end of the electric push rod 91. The lower end of the spring plate 94 is slidably connected to the upper surface of the support seat 6. When the spring plate 94 undergoes elastic deformation, it slides relative to the support seat 6. The spring plate 94 provides a downward force to the support seat 6, ensuring that the lower template 5 is in contact with the upper surface of the U-shaped base plate 1. The electric push rod 91 is floatingly connected to the connecting plate 93 through the connecting shaft 92, ensuring that the electric push rod 91 is not stressed when pressing lightweight high-alumina bricks. The front end of the upper surface of the U-shaped base plate 1 is provided with symmetrically distributed support shafts 10. The upper ends of the support shafts 10 are all fixedly connected to the lower surface of the upper support frame 8, improving the structural strength of the upper support frame 8.
[0024] The working principle of the molding die for producing lightweight high-alumina bricks provided by this utility model is as follows: Before use, the U-shaped base plate 1 is installed on the frame, and the upper template 4 is connected to the pressure rod of the processing equipment. During production, the pressure rod of the processing equipment drives the upper template 4 to move upward and out of the mold box 3, quantitatively adding the high-alumina brick raw material into the mold box 3. The lower template 5 blocks the raw material from flowing out. Then, the pressure rod drives the upper template 4 to move downward to extrude and form the raw material inside the mold box 3. After the lightweight high-alumina brick is formed, the external controller controls the motor 72 to operate. The output shaft of the motor 72 drives the synchronous pulley 73 to rotate. The synchronous pulley 73 drives the lead screw 71 to rotate through the synchronous belt and the synchronous pulley 74. Rod 71 drives the lower template 5 to slide forward along the groove at the lower end of the mold box 3. Then, the telescopic end of the electric push rod 91 retracts, and the telescopic end of the electric push rod 91 drives the connecting shaft 92 to move upward. Initially, the connecting shaft 92 slides relative to the long sliding hole in the middle of the connecting plate 93. After the connecting shaft 92 contacts the upper end of the long sliding hole, the connecting shaft 92 drives the connecting plate 93 to move upward. The connecting plate 93 drives the mold box 3 to slide upward along the sliding column 2 through the support seat 6. The upper template 4 will block the lightweight high alumina brick from moving upward with the mold box 3. Then, the upper template 4 pushes the lightweight high alumina brick out of the mold box 3. The lightweight high alumina brick falls through the opening at the rear end of the U-shaped bottom plate 1 onto the conveyor belt below, which facilitates the transfer of the lightweight high alumina brick.
[0025] It is worth noting that the motor 72 and electric linear actuator 91 disclosed in the above embodiments can be freely configured according to the actual application scenario. The motor 72 can be a servo motor of model R88M-G20030H-S2-Z, and the electric linear actuator 91 can be an electric linear actuator of model ANT-52. The external controller controls the operation of the motor 72 and the electric linear actuator 91 using methods commonly used in the prior art.
