Description

Technical Field

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

[0002] Refractory materials refer to a class of inorganic non-metallic materials with a refractoriness of not less than 1580℃. They are now defined as any material whose physical and chemical properties allow it to be used in a high-temperature environment. When producing shaped refractory materials, the raw materials need to be poured into a mold, compacted and shaped, and then demolded. However, when using the existing demolding device, after the shaped refractory material is removed, residual refractory material is easily stuck to the inner wall of the mold, which requires manual removal by the staff, indirectly reducing the production efficiency of refractory materials. Utility Model Content

[0003] In view of this, the present invention provides a demolding device for refractory material production, which can automatically remove residual material on the inner wall of the mold when demolding the material, eliminating the need for manual cleaning by workers and improving the production efficiency of refractory materials.

[0004] To solve the above-mentioned technical problems, this utility model provides a demolding device for refractory material production, including a workbench with a shaping groove inside. A top plate is installed inside the shaping groove, and an ejection mechanism is also installed inside the shaping groove to move the top plate up and down. A scraping mechanism is installed below the top plate, including a scraper blade with a sharp lower end. The lower end of the scraper blade contacts the inner wall of the shaping groove, and the scraper blade is used to scrape off residual material on the inner wall of the shaping groove. The lower side of the inner wall of the shaping groove, corresponding to the area directly below the scraper blade... The part is equipped with a discharge chute. After the heat-resistant material is shaped in the shaping trough, the worker moves the top plate upward through the ejection mechanism, so that the top plate ejects the heat-resistant material from the shaping trough. If there is material residue on the inner wall of the shaping trough, when the worker moves the top plate downward through the ejection mechanism, the scraper at the bottom of the top plate scrapes the material residue on the inner wall of the shaping trough to the discharge chute, and then discharges it into the workbench through the discharge chute. This can remove the residual material on the inner wall of the mold without the need for manual cleaning by the worker, thus improving the production efficiency of refractory materials.

[0005] There are four scraper blades, each set on the lower part of the four side walls of the top plate. The positions of the four scraper blades can scrape the four inner walls of the shaping groove, improving the scraping effect.

[0006] The scraping mechanism also includes an elastic component, which drives the scraper to apply pressure to the inner wall of the shaping groove. The elastic component can push the scraper to apply a certain pressure to the inner wall of the shaping groove, thereby improving the scraping effect of the scraper on the inner wall of the shaping groove.

[0007] The elastic component includes four elastic cavities formed inside the top plate, each corresponding to the top of each scraper. A movable block is slidably mounted on the inner wall of each elastic cavity. A spring is mounted on one side wall of the movable block, with one end fixed to the side wall of the movable block and the other end fixed to the side wall of the elastic cavity. A connecting block is located at the bottom of the movable block. A groove adapted to the connecting block is formed at the bottom of the elastic cavity, and the connecting block is slidably mounted within the groove. The upper part of the scraper is fixed to the bottom of the connecting block. Each elastic cavity contains two springs, which are compression springs. The springs are located inside the elastic cavity on the side away from the inner wall of the shaping groove. Because the springs are compression springs, when the scraper contacts the inner wall of the shaping groove, the springs are compressed. The movable block compresses the springs, and the springs exert a restoring force towards the movable block. This, in turn, drives the scraper to apply pressure to the inner wall of the shaping groove through the movable block and the connecting block, thereby improving the scraping effect of the scraper on the material inside the shaping groove.

[0008] The ejection mechanism includes a placement groove inside the base, located directly below the shaping groove and connected to it. A telescopic push rod is installed inside the placement groove, with its fixed end fixed inside the groove and its output end fixed to the bottom of the top plate. A shaping mechanism is installed on the upper part of the worktable to compact and shape the raw material in the shaping groove. The worker pours the refractory material into the shaping groove, and then the shaping mechanism compacts the refractory material downwards. Finally, the telescopic push rod is activated, and its output end drives the top plate to rise, causing the top plate to eject the refractory material from the shaping groove.

[0009] The shaping mechanism includes a support frame set on the upper part of the workbench, a hydraulic rod set on the upper part of the support frame, the output end of the hydraulic rod passing through the upper wall of the support frame, and a fixed plate set on the output end of the hydraulic rod. A pressing mold adapted to the shaping groove is installed at the bottom of the fixed plate. The worker pours the refractory material into the shaping groove, and then starts the hydraulic rod. The output end of the hydraulic rod drives the fixed plate and the pressing mold to descend. The pressing mold enters the shaping groove to compact and shape the refractory material in the shaping groove.

[0010] The fixed plate has through holes on both sides, and a matching guide rod is installed through the through holes on both sides of the fixed plate. The upper end of the guide rod is fixed to the lower side of the support frame surface, and the lower end of the guide rod is fixed to the upper surface of the worktable. The guide rod can limit the fixed plate when it descends, prevent the fixed plate from tilting, and improve the stability of the fixed plate during the descent process.

[0011] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0012] 1. When this utility model is used, after the heat-resistant material is shaped in the shaping tank, the worker moves the top plate upward through the ejection mechanism, so that the top plate ejects the heat-resistant material from the shaping tank. If there is material residue on the inner wall of the shaping tank, when the worker moves the top plate downward through the ejection mechanism, the scraper at the bottom of the top plate scrapes the material residue on the inner wall of the shaping tank to the discharge chute, and then discharges it into the workbench through the discharge chute. This removes the residual material on the inner wall of the mold without the need for manual cleaning by the worker, thus improving the production efficiency of refractory materials.

[0013] 2. When this utility model is used, since the spring is a compression spring, when the scraper contacts the inner wall of the shaping groove, the spring is in a compressed state. The movable block compresses the spring, and the spring applies a rebound force towards the movable block. Then, through the movable block and the connecting block, the scraper is driven to apply pressure to the inner wall of the shaping groove, thereby improving the scraping effect of the scraper on the material of the inner wall of the shaping groove.

[0014] 3. When using this utility model, the worker pours the refractory material into the shaping groove, then the shaping mechanism presses the refractory material in the shaping groove downwards, and finally the telescopic push rod is activated. The output end of the telescopic push rod drives the top plate to rise, so that the top plate pushes the refractory material out of the shaping groove.

[0015] 4. When using this utility model, the worker pours the refractory material into the shaping tank, and then starts the hydraulic rod. The output end of the hydraulic rod drives the fixing plate and the pressing mold to descend. The pressing mold enters the shaping tank to compact and shape the refractory material in the shaping tank. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0025] According to one embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown: This embodiment provides a demolding device for refractory material production, including a workbench 100, a shaping groove 200 inside the workbench 100, a top plate 500 inside the shaping groove 200, and an ejection mechanism inside the shaping groove 200. The ejection mechanism is used to drive the top plate 500 to move up and down. A scraping mechanism is provided at the lower part of the top plate 500. The scraping mechanism includes a scraper 600, and the lower end of the scraper 600 is a sharp structure. The lower end of the scraper 600 contacts the inner wall of the shaping groove 200. The scraper 600 is used to scrape off the residual material on the inner wall of the shaping groove 200. A discharge groove 201 is provided on the lower side of the inner wall of the shaping groove 200, corresponding to the position directly below the scraper 600. After the refractory material is shaped in the shaping groove 200, the worker... The operator moves the top plate 500 upward via the ejection mechanism, causing it to eject the heat-resistant material from the shaping groove 200. If material residue remains on the inner wall of the shaping groove 200, the scraper 600 at the bottom of the top plate 500 scrapes the residue off the inner wall of the shaping groove 200 to the discharge groove 201, and then discharges it into the workbench 100 through the discharge groove 201. This removes residual material from the inner wall of the mold without requiring manual cleaning, thus improving the production efficiency of refractory materials. There are four scraper blades 600, each positioned on the lower part of the four side walls of the top plate 500. The positions of the four scraper blades 600 can scrape all four inner walls of the shaping groove 200, improving the scraping effect.

[0026] The scraping mechanism also includes an elastic component, which drives the scraper 600 to apply pressure to the inner wall of the shaping groove 200. The elastic component can push the scraper 600 to apply a certain pressure to the inner wall of the shaping groove 200, thereby improving the scraping effect of the scraper 600 on the residual material on the inner wall of the shaping groove 200. The elastic component includes four elastic cavities 601 formed inside the top plate 500. Each elastic cavity 601 corresponds to the area directly above each scraper 600. A movable block 602 is slidably arranged on the inner wall of the elastic cavity 601. A spring 604 is arranged on one side wall of the movable block 602. One end of the spring 604 is fixed to one side wall of the movable block 602, and the other end of the spring 604 is fixed to one side wall of the elastic cavity 601. A connecting block 603 is provided at the bottom of the movable block 602, and a connecting block 603 is provided at the bottom of the elastic cavity 601. The sliding groove is adapted to the connecting block 603, and the connecting block 603 is slidably disposed in the sliding groove. The upper part of the scraper 600 is fixed to the bottom of the connecting block 603. There are two springs 604 inside each elastic cavity 601, and the springs 604 are compression springs 604. The springs 604 are disposed inside the elastic cavity 601 and located on the side away from the inner wall of the shaping groove 200. Since the springs 604 are compression springs 604, when the scraper 600 contacts the inner wall of the shaping groove 200, the springs 604 are in a compressed state. The movable block 602 compresses the springs 604, and the springs 604 apply a rebound force in the direction of the movable block 602. In turn, the movable block 602 and the connecting block 603 drive the scraper 600 to apply pressure to the inner wall of the shaping groove 200, thereby improving the scraping effect of the scraper 600 on the inner wall of the shaping groove 200.

[0027] According to another embodiment of the present invention, such as Figure 5 and Figure 6 As shown, the ejection mechanism includes a placement groove inside the base, located directly below the shaping groove 200 and connected to it. A telescopic push rod 400 is installed inside the placement groove, with its fixed end fixed inside the groove and its output end fixed to the bottom of the top plate 500. A shaping mechanism is installed on the upper part of the workbench 100. The shaping mechanism is used to compact and shape the raw material in the shaping groove 200. The worker pours the refractory material into the shaping groove 200, and then the shaping mechanism compacts the refractory material in the shaping groove 200 downwards. Finally, the telescopic push rod 400 is activated, and the output end of the telescopic push rod 400 drives the top plate 500 to rise, causing the top plate 500 to eject the refractory material from the shaping groove 200.

[0028] The shaping mechanism includes a support frame 300 mounted on the upper part of the workbench 100. A hydraulic rod 301 is mounted on the upper part of the support frame 300. The output end of the hydraulic rod 301 passes through the upper wall of the support frame 300, and a fixing plate 302 is mounted on the output end of the hydraulic rod 301. A pressing mold 303 adapted to the shaping groove 200 is installed at the bottom of the fixing plate 302. When the operator pours refractory material into the shaping groove 200, the hydraulic rod 301 is activated. The output end of the hydraulic rod 301 drives the fixing plate 302 and the pressing mold 303 to descend, and the pressing mold 303 enters... The refractory material in the shaping groove 200 is compacted and shaped by the refractory material in the shaping groove 200. The fixing plate 302 has through holes on both sides, and a matching guide rod 304 is installed through the through holes on both sides of the fixing plate 302. The upper end of the guide rod 304 is fixed to the lower side of the surface of the support frame 300, and the lower end of the guide rod 304 is fixed to the upper surface of the workbench 100. The guide rod 304 can limit the fixing plate 302 when it descends, prevent the fixing plate 302 from tilting, and improve the stability of the fixing plate 302 during the descent process.

[0029] How to use this utility model:

[0030] Workers pour refractory material into the shaping groove 200, then activate the hydraulic rod 301. The output end of the hydraulic rod 301 drives the fixed plate 302 and the pressing mold 303 to descend. The pressing mold 303 enters the shaping groove 200 to compact and shape the refractory material. Finally, the telescopic push rod 400 is activated. The output end of the telescopic push rod 400 drives the top plate 500 to rise, causing the top plate 500 to push the refractory material out of the shaping groove 200. If there is material residue adhering to the inner wall of the shaping groove 200, when the worker lowers the top plate 500 by using the telescopic push rod 400, because the spring 604 is a pressure spring, when the scraper 600 contacts the shaping groove 200... When the inner wall of the mold is being demolded, the spring 604 is compressed. The movable block 602 compresses the spring 604, and the spring 604 applies a rebound force towards the movable block 602. This, in turn, drives the scraper 600 to apply pressure to the inner wall of the molding groove 200 through the movable block 602 and the connecting block 603. This causes the scraper 600 at the bottom of the top plate 500 to scrape the material residue on the inner wall of the molding groove 200 to the discharge groove 201, thereby improving the scraping effect of the scraper 600 on the material removal effect on the inner wall of the molding groove 200. This utility model can automatically remove residual material on the inner wall of the mold when demolding the material using the scraper 600, eliminating the need for manual cleaning by workers and improving the production efficiency of refractory materials.

[0031] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
