Description

Technical Field

[0001] The invention relates to the technical field of valve casting production, in particular to a valve casting production device. Background Art

[0002] A valve is a device used to control the flow of gases, liquids, and gases or liquids containing solid powders in various pipelines and equipment. A valve is usually composed of a valve body, a valve cover, a valve seat, opening and closing parts, a driving mechanism, seals, and fasteners. The control function of the valve is achieved by driving the opening and closing parts to rise and fall, slide, swing, or change the size of the flow channel area by the driving mechanism or fluid. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, and non-standard customized valve materials according to their materials. They are widely used in industries such as industry, construction, agriculture, and households. Valve casting refers to the manufacture of various types of valve products through casting technology. During the casting production of valve casting, workers need to stand around the casting equipment for a long time to observe the casting situation at all times to avoid accidents. However, the high-temperature hot air released by the large amount of high-temperature metal solution stored during casting is always emitted upwards, which may cause safety hazards when workers are close to the casting equipment for a long time, and seriously affects the workers' observation of the casting situation. Therefore, we proposed a casting production equipment for valve casting. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a casting production equipment for valve casting, comprising: An upper mold, wherein a square feed hole for easy casting is opened on the upper mold, and first side plates are provided on both sides of the upper mold; A lower mold, which is used to press and dock with the upper mold to form a complete cavity inside, and a second side plate is provided on both sides of the lower mold; A casting device, which is used to uniformly cast the mold, and a motor is provided on the top of the casting device; A large collar, which is used to perform sleeve-type fixing on the casting device, and a concave side frame is provided on the outer side of the large collar; One side of the upper mold is fixedly connected to one side of the first side plate, one side of the lower mold is fixedly connected to one side of the second side plate, the top of the casting device is fixedly connected to the drive shaft of the motor, the large collar is sleeved on the casting device and fixedly connected to the casting device, the outer side of the large collar is fixedly connected to one side of the concave side frame, and one side of the concave side frame is fixedly connected to one side of the lower mold; Wherein, the casting device comprises: Arc-shaped baffle, which is used to cover and resist the high-temperature gas emitted by the high-temperature molten metal solution in a large area. Four arc-shaped baffles respectively cover four arc-shaped holes in a large area, preventing the high-temperature hot gas released by the large amount of stored high-temperature molten metal from constantly escaping upward, which seriously affects the staff's observation of the casting situation. One side of the arc-shaped baffle is provided with a heat preservation barrel; The outer side of the heat preservation barrel is fixedly connected to one side of the arc-shaped baffle. There are four arc-shaped baffles, and the four arc-shaped baffles are evenly distributed on the outer side of the heat preservation barrel; The top of the concave side frame is fixedly connected with a limiting vertical rod. A double-ring sleeve plate is sleeved and slidably connected to the outer side of the limiting vertical rod. The bottom of the first side plate is fixedly connected with a two-way electric telescopic rod; The double-ring sleeve plate is sleeved on the outer side of the motor and fixedly connected to the motor. The bottom of the two-way electric telescopic rod is fixedly connected to the top of the second side plate; The top of the heat preservation barrel penetrates and is threadedly connected with a threaded long rod. A square vertical hole is opened on the outer side of the threaded long rod. A cleaning mechanism is slidably connected to the inner wall of the square vertical hole. A material cleaning mechanism is fixedly connected to the inner side of the heat preservation barrel. An arc-shaped hole is opened on the outer side of the heat preservation barrel. An upward-inclined upper inclined ring plate is sleeved and fixedly connected to the outer side of the heat preservation barrel. By setting an upward-inclined upper inclined ring plate below the arc-shaped hole on the outer side of the heat preservation barrel to resist the molten metal solution in the heat preservation barrel, it is prevented that when pouring the molten metal solution, the molten metal solution accidentally overflows from the arc-shaped hole to the outside due to limited vision in the heat preservation barrel. Through the inclined surface of the upper inclined ring plate, the solution can flow into the heat preservation barrel through the liquid passing hole and the arc-shaped hole in time without a large accumulation, preventing the molten metal solution from continuously accumulating to a certain height and then the subsequent poured molten metal solution splashing everywhere. A liquid passing hole is opened on the outer side of the heat preservation barrel. By opening a plurality of liquid passing holes at the position between two arc-shaped baffles on the outer side of the heat preservation barrel, it is convenient for the molten metal solution to pass through, preventing a large amount of molten metal solution from gradually overflowing to the outside of the upper inclined ring plate when accumulating too much between the arc-shaped baffles. The bottom of the heat preservation barrel is communicated with a liquid outlet pipe; The outer side of the heat preservation barrel is fixedly connected to the inner side of the large sleeve ring. The top of the threaded long rod is fixedly connected to the driving shaft of the motor. There are four arc-shaped holes, and the four arc-shaped holes are evenly distributed on the outer side of the heat preservation barrel. There are a plurality of liquid passing holes, and the plurality of liquid passing holes are evenly distributed on the outer side of the heat preservation barrel.

[0004] Further, the cleaning mechanism includes a square scraping plate. When the square scraping plate rotates along with the threaded long rod, it slides and scrapes the inner wall of the heat preservation barrel, preventing the high-temperature molten metal solution in the heat preservation barrel from adhering to the inner wall of the heat preservation barrel due to long-term non-flow. A square hole is formed on one side of the square scraping plate, and a corrugated strip is fixedly connected to the inner wall of the square hole. When multiple corrugated strips rotate, they evenly stir and disperse the high-temperature molten metal solution in the heat preservation barrel, preventing the high-temperature molten metal solution in the heat preservation barrel from stagnating and not flowing for a long time, resulting in uneven local temperature and poor fluidity. Oblique baffles are fixedly connected to both sides of the square scraping plate. When the molten metal solution is pushed, it gradually moves along the inclined surface of the oblique baffle towards the position of the liquid outlet pipe at the center of the heat preservation barrel, preventing a large amount of residual molten metal solution from being distributed at the position near the inner wall of the bottom of the heat preservation barrel and being difficult to discharge smoothly. A bottom-opening square groove is formed at the bottom of the oblique baffle. By providing a bottom-opening square groove at the bottom of the oblique baffle, it is convenient for the molten metal solution to pass through in sequence, preventing a part of the molten metal solution pushed by the oblique baffle from accumulating in the area between the two oblique baffles and being difficult to discharge. The outer side of the square scraping plate is slidably connected to the inner wall of the square vertical hole. There are two square holes, and the two square holes are evenly distributed on one side of the square scraping plate. There are multiple corrugated strips, and the multiple corrugated strips are evenly distributed on both sides of the inner wall of the square hole. There are multiple oblique baffles, and the multiple oblique baffles are evenly distributed on both sides of the square scraping plate.

[0005] Further, the material cleaning mechanism includes an annular inclined plate. The annular inclined plate slides and scrapes the outer threaded surface of the rotating and upward-moving threaded long rod, preventing part of the molten metal solution from remaining on the outer threaded surface of the threaded long rod and causing jamming during its rotation. A rigid brush is fixedly connected to the inner side of the annular inclined plate. The rigid brush performs hard friction cleaning on the inner threaded surface of the rotating and upward-moving threaded long rod, preventing part of the molten metal solution that is still difficult to scrape off by the annular inclined plate from remaining on the inner threaded surface of the threaded long rod and affecting its use. An inclined surface round hole is formed on the inner side of the annular inclined plate. By providing multiple inclined surface round holes, it is convenient for the continuously accumulating molten metal solution to be discharged in a timely manner, preventing the cleaned molten metal solution from continuously accumulating in the relatively low-temperature area at the top of the heat preservation barrel and being difficult to handle after solidification. A corrugated long piece is fixedly connected to the outer side of the annular inclined plate. Dense brushes are fixedly connected to both sides of the corrugated long piece. The dense brushes perform friction cleaning on the side surface of the square scraping plate, the corrugated strips in the square hole, and the surface of the oblique baffle, preventing the surfaces of the square scraping plate, the corrugated strips, and the oblique baffle from being attached with the stirred residual molten metal solution and being difficult to handle after long-term use. The top of the annular inclined plate is fixedly connected to the inner wall of the heat preservation barrel. There are two corrugated long pieces, and the two corrugated long pieces are evenly distributed on the outer side of the annular inclined plate.

When a plurality of corrugated strips rotate, they evenly stir and disperse the high-temperature molten metal in the heat preservation barrel, preventing the high-temperature molten metal in the heat preservation barrel from stagnating and not flowing for a long time, resulting in poor fluidity due to uneven local temperature. When the molten metal is pushed, it gradually moves along the inclined surface of the inclined baffle towards the position of the liquid outlet pipe at the center of the heat preservation barrel, preventing a large amount of residual molten metal from being distributed at the bottom of the heat preservation barrel near the inner wall and being difficult to drain smoothly. By opening a bottom square groove at the bottom of the inclined baffle, it is convenient for the molten metal to pass through in sequence, preventing part of the molten metal pushed by the inclined baffle from accumulating in the area between the two inclined baffles and being difficult to drain.

[0013] For the second embodiment, please refer to Figures 1 - 8, the present invention provides a casting production device for valve casting: The cleaning mechanism 505 includes a square scraping plate 5051. A square hole 5052 is formed on one side of the square scraping plate 5051. A corrugated strip 5053 is fixedly connected to the inner wall of the square hole 5052.

When in use, the threaded long rod 503 rotates, driving the square scraper 5051 in the square vertical hole 504 to rotate together. When the square scraper 5051 rotates, the outer side is in constant contact with the inner wall of the insulation barrel 502. The square scraper 5051 slides and scrapes the inner wall of the insulation barrel 502 as the threaded long rod 503 rotates. When the square scraper 5051 rotates, it drives the corrugated strips 5053 in the square hole 5052 to rotate together. When the multiple corrugated strips 5053 rotate, the high-temperature metal solution in the insulation barrel 502 is evenly stirred and broken up. When the square scraper 5051 rotates, it drives the inclined baffles 505 on both sides. 4 rotates together, and the bottom of the inclined baffle 5054 is in contact with the bottom of the insulation barrel 502 at all times when it rotates.

[0014] When the present invention is operated, before casting, the first side plate 2 at the top is driven to move upward by the bidirectional electric telescopic rod 11. The upward movement of the first side plate 2 drives the upper mold 1 to move upward together. After the upper mold 1 moves up to a distance from the lower mold 3, the staff can carefully clean the inside of the cavity of the upper mold 1 and the lower mold 3. After cleaning, the bidirectional electric telescopic rod 11 is used to drive the upper mold 1 to move down to contact with the lower mold 3 and tightly press it. At this time, the freshly fired high-temperature molten metal is poured into the casting device 5, and the inside of the mold is evenly cast by the casting device 5. When not casting, the motor 6 can be started to drive the parts in the casting device 5 to rotate and stir the high-temperature molten metal, and the high-temperature molten metal is poured onto the two arc baffles 50. 1, the high-temperature metal solution poured into the upper inclined ring plate 508 is located at the position where the liquid outlet hole is opened on the outside of the insulation barrel 502, and a part of the high-temperature metal solution flows into the insulation barrel 502 through the liquid through hole 509, and the other part of the metal solution overflows to both sides of the liquid through hole 509 and flows into the insulation barrel 502 through the arc hole 507. By opening a plurality of liquid through holes 509 at a position between the two arc baffles 501 on the outside of the insulation barrel 502 to facilitate the passage of the metal solution, an upwardly inclined upper inclined ring plate 508 is provided on the outside of the insulation barrel 502 near the bottom of the arc hole 507 to resist the metal solution in the insulation barrel 502, and the high-temperature metal solution flows downward from the upper inclined ring plate 508 and passes through the arc hole 507 and the liquid through hole 50 9 enters the insulation barrel 502, and the inclined surface of the upper inclined ring plate 508 facilitates the solution to flow into the insulation barrel 502 in time through the liquid through hole 509 and the arc hole 507 without a large amount of accumulation. The four arc baffles 501 are respectively arranged at positions corresponding to the four arc holes 507. The four arc baffles 501 cover the four arc holes 507 with a large area. After the metal solution is poured in, the motor 6 is started to drive the threaded long rod 503 to rotate. Under the rotation limit of the limit vertical rod 9, the threaded long rod 503 is rotated and moved upward. When the threaded long rod 503 rotates and moves upward, it drives the cleaning mechanism 505 in the square vertical hole 504 to move upward together. When the cleaning mechanism 505 rotates and moves upward, it gradually contacts with the cleaning mechanism 506. The cleaning mechanism 506 rotates and moves upward. The threaded long rod 503 and the cleaning mechanism 505 perform self-cleaning together. When the threaded long rod 503 rotates and moves upward to the top of the liquid outlet pipe 510, the high-temperature metal solution in the insulation barrel 502 flows into the mold through the liquid outlet pipe 510 for casting. When the threaded long rod 503 rotates, it drives the square scraper 5051 in the square vertical hole 504 to rotate together. When the square scraper 5051 rotates, the outer side of the square scraper 5051 is in constant contact with the inner wall of the insulation barrel 502. As the threaded long rod 503 rotates, the square scraper 5051 slides and scrapes the inner wall of the insulation barrel 502. When the square scraper 5051 rotates, it drives the corrugated strips 5053 in the square hole 5052 to rotate together. When multiple corrugated strips 5053 rotate, the high-temperature metal solution in the insulation barrel 502 is evenly stirred and dispersed.When the square scraping plate 5051 rotates, it drives the inclined baffles 5054 on both sides to rotate together. When the inclined baffles 5054 rotate, the bottom always contacts the bottom of the heat preservation barrel 502. As the inclined baffles 5054 rotate with the square scraping plate 5051, they continuously push the residual molten metal solution at the bottom of the heat preservation barrel 502 to move. When the molten metal solution is pushed, it gradually moves along the inclined surface of the inclined baffle 5054 towards the position of the liquid outlet pipe 510 at the center of the heat preservation barrel 502. By opening a bottom square groove 5055 at the bottom of the inclined baffle 5054, it is convenient for the molten metal solution to pass through in sequence. When the threaded long rod 503 gradually moves up to the point where the bottom of the square scraping plate 5051 contacts the inner bottom of the square vertical hole 504, the square scraping plate 5051 rotates and moves up together with the threaded long rod 503. When the directional scraping plate rotates and moves up, it gradually approaches the material cleaning mechanism 506 and makes a toggling contact with the material cleaning mechanism 506. When the threaded long rod 503 rotates and moves up, the position near the bottom on the inner side of the annular inclined plate 5061 always contacts the external thread surface of the threaded long rod 503. The annular inclined plate 5061 slides and scrapes the external thread surface of the rotating and moving-up threaded long rod 503. Both the hard brush 5062 and the dense brush 5065 are made of high-temperature heat-resistant materials. At the same time, the hard brush 5062 on the inner side of the annular inclined plate 5061 also always contacts the internal thread surface of the threaded long rod 503. The hard brush 5062 performs hard friction cleaning on the internal thread surface of the rotating and moving-up threaded long rod 503. When the molten metal solution scraped off on the inner side of the annular inclined plate 5061 accumulates more, it gradually falls outward from the inclined surface round hole 5063. By opening multiple inclined surface round holes 5063, it is convenient for the continuously accumulating molten metal solution to be discharged in time. When the square scraping plate 5051 rotates and moves up with the threaded long rod 503, it makes a toggling contact with the corrugated long piece 5064. When the square scraping plate 5051 passes through the corrugated long piece 5064, it makes a frictional contact with the dense brush 5065 on its surface. The dense brush 5065 performs frictional cleaning on the side surface of the square scraping plate 5051, the corrugated strips 5053 in the square hole 5052, and the surface of the inclined baffle 5054.,
