Description

Technical Field

[0001] This utility model relates to the field of refractory materials technology, specifically to a rapid demolding device for corundum furnace tube molds. Background Technology

[0002] Corundum furnace tubes are made of corundum sand (Al2O3) with high hardness, chemical stability, and strong corrosion resistance, and are sintered at high temperatures. As a result, they have high strength, high temperature resistance, and corrosion resistance, making them suitable for various laboratory metal and non-metal sample analysis and molten materials. They are also highly resistant to acids and alkalis, erosion, and rapid heating and cooling, resulting in a long service life. During the production of corundum tubes, they need to be demolded from the mold after casting and curing to facilitate subsequent processing operations.

[0003] The existing publicly available technology, application number CN202321233665.8, describes a rapid demolding device for composite material molding molds. It installs a fixed base by setting an installation box, installs a positioning base by setting a fixed base, installs an upper mold by setting an installation base, limits the first slider by setting a first sliding groove to prevent the first slider from shaking during movement, and drives the inclined block by setting a second cylinder to indirectly move the position of the fixed block.

[0004] However, the above-mentioned patent still has certain drawbacks in use: it ejects the molded finished product by moving the ejector plate, but the friction between the inner wall of the mold and the finished product during ejection not only makes demolding slow and difficult, but also causes scratches on the surface of the finished product, thereby reducing the quality of the finished product and making it difficult to use in the future. The overall use effect is not ideal.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] (a) Technical problems to be solved

[0010] A rapid demolding device for a corundum furnace tube mold includes a base and a top plate. A bottom plate is fixedly installed at the middle of the top of the base. A first adjustment groove and a second adjustment groove are staggered below the bottom plate, with the first adjustment groove located above the second adjustment groove. A first bidirectional lead screw is installed inside the first adjustment groove. One end of the first bidirectional lead screw passes through one side of the base and is connected to a first motor.

A second bidirectional lead screw is installed inside the second adjustment groove. One end of the second bidirectional lead screw passes through one side of the base and is connected to a second motor. Transverse plates are symmetrically sleeved on the outer periphery of both sides of the second bidirectional lead screw.

[0011] Furthermore, several sets of support rods are welded around the top of the base, and a top plate is welded to the top of each support rod.

[0012] Furthermore, hydraulic rods are symmetrically installed at the middle position of the bottom of the top plate, and an upper mold is installed at one end of each hydraulic rod.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a rapid demolding device for corundum furnace tube molds, which has the following beneficial effects:

[0020] This invention employs a first motor and a second motor. After the clay material has solidified, the reverse rotation of the first and second motors drives the transverse and longitudinal plates to move outward synchronously, thereby exposing the corundum furnace tube. At this point, the mold can be demolded. Since multiple sets of plates move outward synchronously during the overall demolding process, the demolding efficiency can be improved. Furthermore, since there is no friction between the molded corundum furnace tube and the demolding process, the wear and tear on the corundum furnace tube caused by friction can be effectively reduced, ensuring its quality and facilitating better subsequent use. It has the advantages of high demolding efficiency, convenient demolding, and good performance. Attached Figure Description

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0029] According to an embodiment of the present invention, a rapid demolding device for corundum furnace tube molds is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a quick demolding device for a corundum furnace tube mold according to an embodiment of the present invention includes a base 1 and a top plate 10. A bottom plate 2 is fixedly installed at the middle of the top of the base 1. A first adjustment groove 4 and a second adjustment groove 14 are staggered below the bottom plate 2, with the first adjustment groove 4 located above the second adjustment groove 14. A first bidirectional lead screw 6 is installed inside the first adjustment groove 4. One end of the first bidirectional lead screw 6 passes through one side of the base 1 and is connected to a first motor 5. Longitudinal plates 3 are symmetrically sleeved on the outer periphery of both sides of the first bidirectional lead screw 6. A second bidirectional lead screw 15 is installed inside the second adjustment groove 14. One end of the second bidirectional lead screw 15 passes through one side of the base 1 and is connected to a second motor 16. Transverse plates 8 are symmetrically sleeved on the outer periphery of both sides of the second bidirectional lead screw 15.

[0031] In one embodiment, a number of support rods 7 are welded around the top of the base 1, and a top plate 10 is welded to the top of the support rods 7.

[0032] In one embodiment, hydraulic rods 11 are symmetrically installed at the bottom center of the top plate 10, and an upper mold 9 is installed at one end of the hydraulic rod 11. The upper mold 9 is set up to be used in conjunction with the lower mold formed by the longitudinal plate 3, the bottom plate 2 and the transverse plate 8, thereby facilitating the production and use of corundum furnace tubes.

[0033] In one embodiment, a number of sets of docking grooves 18 are symmetrically formed around the perimeter of the base plate 2.

[0034] In one embodiment, a mating strip 17 is installed at the bottom of both the longitudinal plate 3 and the transverse plate 8. The mating strip 17 and the mating groove 18 are provided to ensure that the longitudinal plate 3 and the transverse plate 8 can be accurately fitted to the outer periphery of the base plate 2, thereby realizing the lower mold construction operation and ensuring that no gaps will appear when corundum clay is added later, thus preventing leakage.

[0035] In one embodiment, several sets of limiting blocks 12 are symmetrically installed at the top position of the surface of the upper mold 9. The limiting blocks 12 are set to be used in conjunction with the limiting grooves 13 to ensure the accuracy of the docking.

[0036] In one embodiment, a limiting groove 13 is provided at the top center of the surface of the transverse plate 8 and at the top center of the surface of the longitudinal plate 3. The limiting groove 13 is provided to be used in conjunction with the limiting block 12, so that the upper mold 9 can accurately dock with the constructed lower mold, thereby improving the production quality of the corundum furnace tube. At the same time, the structure of the upper mold 9 and the lower mold surface is adapted to the structure of the corundum furnace tube. For example, grooves or protrusions can be provided on the surface, so that the cavity shape constructed after the two are used together is the structural shape of the corundum furnace tube. Since the size types of corundum furnace tubes are diverse, the concave and convex structures provided on the surfaces of the upper mold 9 and the lower mold also need to be adjusted accordingly, which will not be elaborated in detail here.

[0037] In one embodiment, a controller is installed on one side of the base 1. The controller is set up to control the equipment in the structure. Since there are various types of controllers and the application technology is mature, personnel can select one according to their needs and implement it through programming.

[0038] Working principle: In actual use, the operation of the first motor 5 and the second motor 16 can drive the first bidirectional lead screw 6 and the second bidirectional lead screw 15 to rotate, thereby causing multiple sets of longitudinal plates 3 and transverse plates 8 to move. These plates then connect with the mating grooves 18 on the base plate 2 via the mating strips 17 on the surface, causing the longitudinal plates 3 and transverse plates 8 to surround the outer periphery of the base plate 2, thus realizing the construction of the lower mold. Then, personnel can add the corundum clay used in production into the lower mold. Finally, the ejection of the hydraulic rod 11 can drive the upper mold 9 to insert... The material is inserted into the lower mold to shape the corundum furnace tube. After the clay solidifies, the first motor 5 and the second motor 16 reverse their rotation to move the horizontal plate 8 and the vertical plate 3 outwards synchronously, exposing the corundum furnace tube. At this point, the mold can be demolded. Since multiple plates move outwards synchronously during the demolding process, the demolding efficiency is improved, and the wear of the corundum furnace tube caused by friction is reduced, ensuring its quality and facilitating better subsequent use. The device as a whole has the advantages of high demolding efficiency, convenient demolding, and good performance.
