Description

Technical Field

[0001] This utility model relates to the field of zirconium corundum brick production technology, specifically a resin mold for the production and processing of electrofused zirconium corundum bricks. Background Technology

[0002] Resin sand molds are required when melting and casting zirconia corundum bricks. Resin sand molds are molds made of resin sand. Before molding and core making, the surface of the sand grains is covered with a solid resin film. They have the characteristics of high strength, high temperature resistance, and easy demolding, and are widely used in the metal casting industry.

[0003] According to application number 202321341800.0 published on the China Patent Network, this utility model discloses a mold core for zirconia-corundum checker bricks, relating to the field of checker brick mold technology. It includes: a forming mold with a base embedded within it; several cores, all fixedly installed on the top of the base; and a stripping mechanism comprising a stripping block and a moving component. Several cores are simultaneously slidably inserted into the stripping block, which is slidably connected to the inner wall of the forming mold. The moving component is fixedly installed on the lower surface of the stripping block, with one end extending to the outside of the forming mold. The beneficial effects of this utility model are... The base is set at the bottom of the forming mold, and multiple cores are set on the base. A stripper block is fitted on the core. After the molten liquid is poured and cooled to form, the checker bricks can be easily unloaded by moving the stripper block upwards. The sealing between the stripper block and the forming mold prevents leakage of the molten liquid during casting, ensuring the forming quality of the checker bricks.

The bottom of the support blocks 14 is fixedly connected to the top of the transmission box 3.

[0021] As a technical optimization of this utility model, by setting a rotating block 10, a pushing block 11, an inserting block 12, a guide rod 13 and a support block 14, the rotating rod 4 can be limited, thus preventing the rotating rod 4 from rotating on its own during use.

[0022] refer to Figure 4 A torsion spring 15 is fitted on the surface of the rotating rod 4. The top of the torsion spring 15 is fixedly connected to the top of the inner wall of the transmission box 3, and the bottom of the torsion spring 15 is fixedly connected to the top of the turntable 5.

[0023] As a technical optimization of this utility model, by setting the torsion spring 15, the rotating rod 4 can be automatically rotated, thereby improving the performance of the rotating rod 4.

[0024] refer to Figure 5 The transmission box 3 has two horizontally fixed limiting rods 16 inside, which pass through the moving plate 8 and are slidably connected to the moving plate 8.

[0025] As a technical optimization of this utility model, by setting the limiting rod 16, the moving plate 8 can be guided, so as to avoid the phenomenon of tilting and jamming of the moving plate 8 during the movement.

[0026] refer to Figure 5 The end of the limiting rod 16 away from the transmission box 3 is fixedly connected to a stop block 17, and the end of the stop block 17 near the transmission box 3 is in contact with the surface of the moving plate 8.

[0027] As a technical optimization of this utility model, by setting the stop 17, the movable plate 8 can be limited to prevent the movable plate 8 from disengaging from the limit rod 16.

[0028] refer to Figure 3 The transmission box 3 has openings 18 on both sides, and the card plate 9 passes through the opening 18 and is slidably connected to the inner wall of the opening 18.

[0029] As a technical optimization of this utility model, by setting the opening 18, the card plate 9 can pass completely through the transmission box 3 for limiting, thereby improving the stability of the card plate 9.

[0030] refer to Figure 3 A spring return device 19 is fitted on the surface of the guide rod 13. The end of the spring return device 19 away from the push block 11 is fixedly connected to the surface of the support block 14.

[0031] As a technical optimization of this utility model, by setting the rebound device 19, the push block 11 can be moved inward automatically, preventing the push block 11 from moving randomly.

[0032] refer to Figure 3 A pull plate 20 is fixedly connected to the top of the card plate 9, and the pull plate 20 is used in conjunction with the card plate 9.

[0033] As a technical optimization of this utility model, by setting the pull plate 20, it is easier for the user to pull the card plate 9 left and right, thus improving the user's comfort.

[0034] The working principle and usage process of this utility model are as follows: First, insert the upper mold 1 into the lower mold 2. After insertion, pull the push block 11 outwards. The push block 11 moves the insert block 12 outwards, moving it away from the rotating block 10. After this, the user rotates the rotating block 10. The rotating block 10 rotates the rotating rod 4, which in turn rotates the turntable 5. The turntable 5 rotates the pull rod 6. While rotating, the pull rod 6 pulls the traction rod 7 inwards. The traction rod 7 moves the moving plate 8 inwards, which in turn moves the clamping plate 9 inwards, pressing the clamping plate 9 firmly against the bottom of the lower mold 2. After this pressing, release the push block 11. The spring force of the spring mechanism 19 moves the push block 11 and the insert block 12 inwards, inserting the insert block 12 into the interior of the rotating block 10 to fix it. Finally, to remove the casting, reverse the above steps.

[0035] In summary, this resin mold for the production and processing of fused zirconia-corundum bricks, by setting a clamping plate 9, can fix the upper mold 1 and the lower mold 2, preventing the mold from shaking during casting. By setting a transmission box 3, rotating rod 4, turntable 5, pull rod 6, traction rod 7 and moving plate 8, the clamping plate 9 can be moved left and right, improving the performance of the clamping plate 9. By setting a rotating block 10, push block 11, insert block 12, guide rod 13 and support block 14, the rotating rod 4 can be fixed, preventing the rotating rod 4 from rotating arbitrarily. This provides the advantage of easy fixation and solves the problem that during casting, the rolling of the molten solution can cause the upper mold to shake, resulting in air cavities in the castings inside the mold. This previously required the user to use external pressure to tighten the mold for casting, increasing the user's operating difficulty and reducing the practicality of the mold.
