Description

Technical Field

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

[0002] Refractory materials are materials specifically designed to resist high temperatures and chemical corrosion. They are widely used in high-temperature equipment in industries such as metallurgy, glass, cement, and chemicals. These materials include refractory bricks, refractory castables, refractory coatings, and refractory fibers. Refractory bricks are made of refractory clay or high-alumina materials and are used to line furnaces, smelters, and high-temperature reaction chambers. They have good high-temperature resistance and chemical stability. Refractory castables are mainly composed of refractory powder and water glass and are used to repair and fill furnace walls and furnace bottoms of high-temperature equipment.

[0003] Refractory coatings are applied to the surface of equipment to increase its resistance to high temperatures and corrosion. They are usually composed of silicate and alumina powders. Refractory fibers are made of ceramic fibers, which are lightweight and have excellent thermal insulation properties. They are widely used in thermal insulation pads and insulation layers. These materials not only protect equipment from high temperatures and chemical corrosion, but also improve production efficiency and extend equipment service life, meeting the requirements of modern industry for safety, environmental protection and economic benefits.

[0004] Refractory precast components are cast using molds. During the solidification process of the refractory material, it is necessary to remove the air inside to ensure the density and strength of the precast component. However, the traditional method of removing air is to manually use a vibrating pump to move back and forth inside the mold to remove the air. This method is not only time-consuming and labor-intensive, but also inefficient. Therefore, a new type of demolding device for refractory material production is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a demolding device for the production of novel refractory materials, which aims to improve the problem that traditional air removal methods are not only time-consuming and labor-intensive, but also inefficient.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a demolding device for producing novel refractory materials, comprising a fixed frame, a motor fixedly connected to the top left side of the fixed frame, a rotating rod fixedly connected to the output end of the motor, a mold fixedly connected to the top of the fixed frame, a shell fixedly connected to the bottom of the mold, a support rod slidably connected inside the shell, a sliding plate fixedly connected to the upper side of the support rod, a spring fixedly connected to the bottom of the sliding plate, a fixed rod fixedly connected to the bottom of the support rod, and an ejection assembly installed at the bottom of the mold. The ejection assembly facilitates demolding by ejecting the refractory material preform.

[0007] As a further description of the above technical solution: The ejection assembly includes an electric push rod, the top of which is fixedly connected to the front side of the mold. A pressure rod is slidably connected to the output end of the electric push rod. Two fixed plates are rotatably connected to the middle of the pressure rod. A sliding frame is slidably connected to the rear side of the pressure rod. A push rod is fixedly connected to the rear end of the sliding frame. A baffle is fixedly connected to the outside of the push rod. A spring is fixedly connected to the top of the baffle. A top plate is fixedly connected to the top of the push rod.

[0008] As a further description of the above technical solution: A rubber block is fixedly connected to the top of the support rod, and the top of the rubber block abuts against the bottom of the mold.

[0009] As a further description of the above technical solution: The second spring is internally sleeved on the outside of the support rod, and the bottom end of the second spring is fixedly connected to the bottom wall of the outer shell.

[0010] As a further description of the above technical solution: The outer periphery of the sliding plate is slidably connected to the inner wall of the outer shell, and the fixed rod and the rotating rod abut against each other.

[0011] As a further description of the above technical solution: The top of the push rod is slidably connected inside the mold, and the top of the fixing plate is fixedly connected to the bottom of the mold.

[0012] As a further description of the above technical solution: The spring is internally sleeved on the outside of the push rod, and the top end of the spring is fixedly connected to the bottom of the mold.

[0013] As a further description of the above technical solution: The outer periphery of the top plate is slidably connected to the inner wall of the mold.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the drive motor drives the rotating rod to rotate and continuously press the fixed rod, which drives the support rod to move downward, causing the slide plate to compress the spring and quickly push the rubber block to hit the bottom of the mold to generate vibration, thus expelling air. This saves time and effort, avoids the need for workers to use a vibration pump, and effectively improves work efficiency.

[0015] 2. In this utility model, the electric push rod presses the pressure rod, which is driven to operate under the support of the fixed plate. This causes the sliding frame to move the top rod upward, and the baffle to compress the spring and drive the top plate to work. This solves the problem of demolding and ejecting the refractory precast parts, making it convenient for workers to remove them. The operation is simple, time-saving and labor-saving.

[0020] Specifically, the fixed frame 1 is used to connect and support the device, the motor 2 is used to drive the rotating rod 3 to work, the mold 4 is used to cast refractory precast parts, the outer shell 5 is used to connect and protect the internal parts, the fixed rod 17 is used to withstand the pressure from the rotating rod 3 and drive the support rod 6 to move, the support rod 6 is used to drive the rubber block 18 to impact the bottom of the mold 4 and generate vibration, the sliding plate 15 is used to compress the second spring 16 and store force for the second spring 16, the second spring 16 is used to drive the support rod 6 to move upward to achieve impact, and the rubber block 18 is made of rubber to avoid damage to the mold 4 during impact.

[0021] Reference Figure 1 - Figure 4 The ejector assembly includes an electric push rod 14, the top of which is fixedly connected to the front side of the mold 4. A pressure rod 8 is slidably connected to the output end of the electric push rod 14. Two fixed plates 7 are rotatably connected to the middle of the pressure rod 8. A sliding frame 9 is slidably connected to the rear side of the pressure rod 8. A push rod 10 is fixedly connected to the rear end of the sliding frame 9. A baffle 11 is fixedly connected to the outside of the push rod 10. A spring 12 is fixedly connected to the top of the baffle 11. A top plate 13 is fixedly connected to the top of the push rod 10. The upper side of the push rod 10 is slidably connected to the inside of the mold 4. The top of the fixed plate 7 is fixedly connected to the bottom of the mold 4. The spring 12 is sleeved inside the outside of the push rod 10. The top of the spring 12 is fixedly connected to the bottom of the mold 4. The outer periphery of the top plate 13 is slidably connected to the inner wall of the mold 4.

[0022] Specifically, the electric push rod 14 is used to press down the pressure rod 8. The fixed plate 7 is a fulcrum for the pressure rod 8. The rear side of the pressure rod 8 will push the sliding frame 9 in the opposite direction. The front side of the pressure rod 8 has a sliding groove to counteract the bias force of the pressure rod 8. The sliding frame 9 is used to counteract the bias force of the pressure rod 8, so that the force is transmitted vertically upward to the push rod 10.

Through the cooperation of the above parts, the mold 4 can be easily separated from the cast preform.

[0023] Working principle: When casting refractory preforms, the refractory material is first added into the mold 4. The motor 2 is driven by an external power source. The motor 2 drives the rotating rod 3 to rotate, and the rotating rod 3 will continuously press down on the fixed rod 17, causing the support rod 6 to move downwards synchronously. When the rotating rod 3 and the fixed rod 17 are disconnected, the spring 16 will immediately push the sliding plate 15, causing the support rod 6 to push the rubber block 18 to hit the bottom of the mold 4, generating vibration and expelling air. After the air is expelled, the motor 2 is controlled to stop rotating, allowing the mold 4 to remain still for a period of time, allowing the refractory material to solidify and form. After forming, the electric push rod 14 is controlled to extend, and under the support of the fixed plate 7, it drives the pressure rod 8 to push the sliding frame 9 upwards, causing the sliding frame 9 to drive the top rod 10 to move upwards, pushing the top plate 13 to eject the refractory preform, achieving demolding. Then the electric push rod 14 is retracted, and the spring 12 will immediately push the baffle 11 to reset the top rod 10. Then the next piece can be cast. The whole process is time-saving, labor-saving, simple to operate, and effectively improves work efficiency.
