Description

Technical Field

[0001] The invention belongs to the technical field of metal casting, in particular to a metal casting forming device. Background Art

[0002] Casting is the process of melting metal into liquid that meets certain requirements and pouring it into a mold. After cooling, solidification and cleaning, a casting with a predetermined shape, size and performance is obtained. The casting blank is almost formed, so it can achieve the purpose of no mechanical processing or a small amount of processing, which reduces the cost and reduces the production time to a certain extent.

[0003] A Chinese patent application CN118218574A discloses a heat treatment metal casting molding device, which belongs to the technical field of casting molding devices, in order to solve the technical problem that the prior art is not convenient for continuous scraping of slag when scraping slag in aluminum alloy ingot manufacturing, resulting in low scraping efficiency. The present invention is provided with a guide component, a rolling component, a pulling component, a guide bending plate, a scraping component and a supporting component. When the triangular push block moves to the contact baffle, it can drive the moving plate to move. When the moving plate moves, the pull rope will pull the sliding block, so that the scraping plate scrapes from the upper end of the ingot mold, and the impurities on the upper surface of the aluminum alloy molten liquid can be scraped off. After the triangular push block passes over the baffle, the roller will roll along the guide groove plate to the lowest point. Due to the elastic force of the elastic rope and the inclined setting of the inclined rod, the sliding block will slide down the inclined rod to the end, which is convenient for continuous use, and can continuously remove impurities on the upper surface of the aluminum alloy molten liquid, thereby improving the scraping efficiency, and the manufacturing cost is low.

[0004] The above technology can improve the efficiency of scraping slag and has a low manufacturing cost. However, after the scraping operation, due to the high surface temperature of the molten metal and the opening of the upper end of the ingot mold, an oxide layer will quickly form after contact with oxygen, which will reduce the surface finish of the workpiece after the workpiece is formed.

[0055] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0056] like Figures 1 to 10 As shown, a metal casting molding device according to the present invention comprises a casting part, a control mechanism, a protection mechanism, a cleaning mechanism and a transmission mechanism;

[0057] The casting part stores the supporting platform 1, the forming mold 8 and the injection furnace 6. The forming mold 8 is detachably mounted on the upper end surface of the supporting platform 1. The forming mold 8 is used to provide a cavity for workpiece molding.

[0058] The injection furnace 6 is used to store molten metal. A robotic arm is provided outside the supporting platform 1. The injection furnace 6 is controlled to move by the robotic arm. When the injection furnace 6 moves above the forming mold 8, the molten metal in the injection furnace 6 is poured into the inside of the forming mold 8 to facilitate cooling and molding of the molten metal.

[0059] The protective mechanism includes a closing plate 13, a cleaning plate 11 and an air injection nozzle 16. After the molten metal is injected into the molding mold 8, the upper end surface of the molding mold 8 is closed by the closing plate 13. The molding mold 8 is closed by the closing plate 13 to reduce the contact between the molten metal and oxygen, thereby reducing the rate of formation of the oxide layer when the molten metal is molded.

[0060] The gas injection nozzle 16 is arranged on the closing plate 13 and is connected to an external inert gas storage chamber. In this embodiment, the inert gas is selected from common xenon gas. After the closing plate 13 closes the molding mold 8, xenon gas is injected into the molding mold 8 to expel the air, thereby isolating oxygen and reducing oxidation efficiency. After molding, the surface smoothness of the workpiece is improved, thereby improving the processing quality of the workpiece.

[0061] The cleaning plate 11 is arranged on one side of the closing plate 13 and is made of elastic material. The control mechanism is used to control the movement of the closing plate 13. By controlling the height of the cleaning plate 11, the cleaning plate 11 is made flush with the molten metal in the forming mold 8. Then the closing plate 13 is moved to control the movement of the cleaning plate 11, thereby scraping off the slag on the molten metal to achieve the scraping operation. After scraping the slag, the closing plate 13 closes the upper end opening of the forming mold 8 to prevent oxidation after scraping the slag.

[0062] The cleaning mechanism comprises a gantry 12 , a mounting plate 14 , a control cylinder 10 and a scraping plate 23 . The mounting plate 14 moves synchronously with the closing plate 13 , and the bottom of the mounting plate 14 is fixedly connected to the upper end surface of the closing plate 13 .

[0063] The control cylinder 10 is installed on the mounting plate 14 through the gantry 12. The control cylinder 10 is a common electric telescopic rod. The control cylinder 10 controls the lifting and lowering of the scraping plate 23 and scrapes the cleaning plate 11. The gantry 12 is fixedly installed on the upper end surface of the mounting plate 14, and the control cylinder 10 is arranged at the upper end of the gantry 12.

[0064] After the cleaning plate 11 scrapes the residue, the scraping plate 23 scrapes the solidified residue on the outer wall of the cleaning plate 11 along the outer wall of the cleaning plate 11 to achieve self-cleaning of the cleaning plate 11 for the next use.

[0065] The transmission mechanism is used to knock the scraper plate 23. After the slag and molten metal solidify, the resistance during scraping increases. At this time, knocking the scraper plate 23 can improve the efficiency of removing and cleaning the slag.

[0066] As a preferred embodiment of the present invention, the control mechanism includes a carrier frame 5, a sliding platform 4, a lifting cylinder 3, a slide plate 2 and a feed cylinder 15, wherein the lifting cylinder 3 and the feed cylinder 15 are both common hydraulic cylinders.

[0067] The supporting frame 5 is fixedly mounted on the side wall of the supporting platform 1, the lifting cylinder 3 is fixedly mounted on the outer wall of the supporting frame 5, the sliding platform 4 is slidably arranged in the supporting frame 5, and the lifting and lowering is controlled by the lifting cylinder 3, wherein the bottom of the supporting frame 5 is fixedly connected to the movable end of the lifting cylinder 3, and the lifting and lowering of the sliding platform 4 is then controlled by the lifting cylinder 3.

[0068] The slide plate 2 is slidably mounted on the outer wall of the carrier frame 5, the feed cylinder 15 is fixedly mounted on the upper end surface of the sliding table 4, and the movable end of the feed cylinder 15 is fixedly connected to the outer wall of the closing plate 13, and the sliding of the closing plate 13 is controlled by the feed cylinder 15.

[0069] The outer wall of the slide plate 2 is fixedly connected to the outer wall of the mounting plate 14 . During the sliding process of the closing plate 13 , the sliding stability of the closing plate 13 is improved by connecting the mounting plate 14 and the slide plate 2 .

[0070] When it is necessary to control the lifting of the closing plate 13, the lifting cylinder 3 controls the lifting of the sliding table 4, and then controls the synchronous lifting of the feed cylinder 15 and the closing plate 13. When the cleaning plate 11 is scraping the residue, the feeding cylinder 15 controls the closing plate 13 to move in the horizontal direction, thereby achieving the scraping effect.

[0071] As a preferred embodiment of the present invention, a mounting cylinder 21 is fixedly mounted on the movable end of the control cylinder 10 , and the mounting cylinder 21 is controlled to rise and fall by the control cylinder 10 .

[0072] The inner wall of the mounting tube 21 is elastically mounted with a force block 19 , a blocking ring for limiting the maximum sliding stroke of the force block 19 is arranged inside the mounting tube 21 , a spring is arranged at the bottom of the force block 19 , and the other end of the spring is connected to the inner wall of the mounting tube 21 .

[0073] A connecting rod 25 is fixedly installed on the bottom surface of the force block 19, and the bottom of the connecting rod 25 is fixedly connected to the upper end surface of the scraper plate 23. The mounting tube 21 is controlled to slide downward by the control cylinder 10. At this time, the blocking ring top presses the force block 19 to drive the scraper plate 23 to slide, so as to scrape off the solidified residue on the outer wall of the cleaning plate 11.

[0074] The transmission mechanism includes a storage cylinder 18 , a control plug 28 and a knock rod 30 . The storage cylinder 18 is fixedly mounted on the inner wall of the mounting cylinder 21 , and an air inlet is arranged on the outside, through which gas is injected into the storage cylinder 18 .

[0075] The outer wall of the control plug 28 is sealed to the inner wall of the storage tube 18, and the bottom of the control plug 28 is connected to the inner wall of the storage tube 18 via an elastic member. After external gas is injected into the storage tube 18, the control plug 28 is driven to slide by the gas pressure.

[0076] The knocking rod 30 is fixedly installed at the bottom of the control plug 28, and the outer wall is slidably fitted with the inner wall of the storage tube 18. The control plug 28 is reset by pulling the elastic force of the elastic member, driving the knocking rod 30 to knock the force block 19, thereby realizing the knocking of the scraper plate 23. The instantaneous kinetic energy generated during the knocking assists the residue to fall off the outer wall of the cleaning plate 11, thereby improving the cleaning efficiency. Among them, the elastic member uses a common spring.

[0077] A vent hole is provided on the top of the control plug 28;

[0078] When the exhaust hole is blocked, air is inflated in the storage tube 18 of the air inlet box, and the sliding elastic part of the control plug 28 stores elastic potential energy. When the exhaust hole is blocked, the inner chamber of the storage tube 18 on the lower side of the control plug 28 is closed, and the injected gas drives the control plug 28 to slide upward.

[0079] After the inner cavity of the storage tube 18 is inflated, the exhaust hole is opened, and the elastic member releases elastic potential energy, driving the control plug 28 to reset, and the tapping rod 30 taps the force block 19. When the exhaust hole is opened, the gas in the inner cavity of the storage tube 18 is discharged. At this time, the elastic member releases elastic potential energy to drive the control plug 28 and the tapping rod 30 to descend, thereby achieving the effect of tapping the force block 19.

[0080] As a preferred embodiment of the present invention, a friction plate 27 is fixedly installed on the upper end surface of the control plug 28, and rubber is arranged inside the friction plate 27. A sealing rod 38 is slidably installed in the exhaust hole at the upper end of the control plug 28. The outer wall of the sealing rod 38 is connected to the inner wall of the friction plate 27 by friction force, and the fixing of the sealing rod 38 and the friction plate 27 is achieved by friction force.

[0081] The outer wall of the blocking rod 38 is provided with a notch for gas to pass through. When the blocking rod 38 is slid until the notch is aligned with the exhaust hole, the exhaust hole is connected. When the blocking rod 38 is slid until the solid section at the bottom of the blocking rod 38 is aligned with the exhaust hole, the exhaust hole is blocked.

[0082] An upper push rod 26 is fixedly installed on the top of the storage cylinder 18, and a lower push rod 29 is fixedly installed on the bottom of the storage cylinder 18. The positions of the upper push rod 26 and the lower push rod 29 correspond to the position of the blocking rod 38, and the upper push rod 26 and the lower push rod 29 are located on the active trajectory of the blocking rod 38 when the control plug 28 slides.

[0083] When gas is injected into the storage tube 18, the control plug 28 slides upward until the sealing rod 38 contacts the upper push rod 26. The gas injection continues and the upper push rod 26 pushes the sealing rod 38, causing the sealing rod 38 and the control plug 28 to slide relative to each other until the notch of the sealing rod 38 is aligned with the exhaust hole. At this time, the exhaust hole remains in a conductive state, and the control plug 28 is reset by the elastic member, and the knocking rod 30 knocks the top of the force block 19.

[0084] When the elastic member drives the control plug 28 to slide down, the lower pressing rod 29 presses the blocking rod 38, so that the blocking rod 38 and the control plug 28 slide relative to each other until the solid section at the bottom of the blocking rod 38 is aligned with the exhaust hole, and the exhaust hole is blocked. After the blocking, air is continuously injected into the storage tube 18, so that the control plug 28 can be lifted again to prepare for the next knock.

[0085] As a preferred embodiment of the present invention, a collecting pool 7 is fixedly installed on the outer wall of the supporting platform 1. After the closing plate 13 is covered with the forming mold 8, the cleaning plate 11 is located directly above the collecting pool 7, and the residue falling off from the outer wall of the cleaning plate 11 falls into the collecting pool 7 to be collected.

[0086] An air outlet is provided on the upper end surface of the closing plate 13, and a sealing plate 17 is provided on the upper end surface of the closing plate 13 for one-way sealing of the air outlet. When the gas injection nozzle 16 injects inert gas, the gas in the molding mold 8 is discharged through the air outlet, and one side of the sealing plate 17 is connected to the outer wall of the closing plate 13, thereby realizing one-way sealing of the air outlet and preventing external oxygen from entering the interior of the molding mold 8 again.

[0087] A clamping ear plate 9 for clamping the forming mold 8 is detachably mounted on the upper end surface of the bearing platform 1 . The clamping ear plate 9 is connected to the bearing platform 1 by bolts and is used to clamp the forming mold 8 to fix the forming mold 8 .

[0088] As a preferred embodiment of the present invention, a storage box 31 is fixedly installed on the upper end surface of the closing plate 13. The inner cavity of the storage box 31 is used to store evaporative liquid. In this embodiment, the evaporative liquid is common pure water. A connecting pipe 32 is fixedly installed on the outer wall of the storage box 31. When the storage box 31 is heated, the evaporative liquid vaporizes and expands, and is discharged through the connecting pipe 32.

[0089] After the closing plate 13 is attached to the forming mold 8 , the heat energy of the molten metal is transferred to the storage box 31 , thereby heating the evaporating liquid inside the storage box 31 .

[0090] The upper end surface of the mounting plate 14 is fixedly mounted with an adapter tube 20, and the upper end surface of the adapter tube 20 is provided with a pressure relief port 33 and an adapter nozzle 34. The adapter nozzle 34 is connected with the air inlet of the outer wall of the storage tube 18. After the storage box 31 is heated inside, when the connecting tube 32 is connected with the adapter nozzle 34, gas is injected into the storage tube 18 to control the knocking rod 30 to reciprocately knock the force block 19. When there is no need to knock the force block 19, the connecting tube 32 is controlled to be connected with the pressure relief port 33. At this time, the gas inside the storage box 31 is discharged through the pressure relief port 33.

[0091] In this embodiment, the useless heat generated when the molten metal is formed is used as the kinetic energy for the outer wall of the scraping cleaning plate 11 to knock against the scraping plate 23, thereby achieving reasonable reuse of the heat.

[0092] The outer wall of the storage box 31 is provided with a liquid injection port, and the liquid injection port is used to add evaporative liquid.

[0093] A heat conducting plate is provided at the bottom of the storage box 31 at the contact position with the closing plate 13. The heat conducting plate is a copper plate and is used to improve the heat conduction efficiency.

[0094] The outer wall of the storage box 31 is provided with a preheating plate 39 , the heating end of the preheating plate 39 extends to the inside of the storage box 31 , and the preheating plate 39 is a common resistance heater, which is used to preheat the evaporating liquid after the closing plate 13 is separated from the forming mold 8 .

[0095] As a preferred embodiment of the present invention, a transmission rod 24 is slidably mounted on the upper end surface of the mounting plate 14 , and the mounting plate 14 provides a mounting and sliding position for the transmission rod 24 .

[0096] One end of the transmission rod 24 extends to the inner wall of the adapter tube 20 and is fixedly mounted with a closing plug 37 . The outer wall of the closing plug 37 is slidably fitted with the inner wall of the adapter tube 20 , and the sliding transmission rod 24 drives the closing plug 37 to slide synchronously.

[0097] Slide the closing plug 37 until it moves between the connecting pipe 32 and the pressure relief port 33, and the adapter nozzle 34 is now connected to the connecting pipe 32;

[0098] The closing plug 37 is slid until it slides between the connecting pipe 32 and the adapter nozzle 34 , at which time the pressure relief port 33 is connected to the connecting pipe 32 .

[0099] A transmission bevel block 35 is slidably mounted on the upper end of the mounting plate 14. The inclined surface of the transmission bevel block 35 is located directly below the mounting tube 21. When the mounting tube 21 slides down, the bottom of the mounting tube 21 presses against the inclined surface of the transmission bevel block 35, thereby controlling the transmission bevel block 35 to slide.

[0100] A support plate 36 is fixedly mounted on the outer wall of the mounting plate 14 , and the side wall of the support plate 36 is elastically connected to the outer wall of the transmission bevel block 35 . After the transmission bevel block 35 slides, the transmission bevel block 35 is reset by controlling the elastic force.

[0101] The transmission plate 22 is rotatably mounted on the outer wall of the transmission bevel block 35 , and the other end of the transmission plate 22 is rotatably connected to the outer wall of the transmission rod 24 . When the transmission bevel block 35 slides, the transmission rod 24 is driven to slide through the transmission plate 22 , thereby controlling the closing plug 37 to slide.

[0102] When scraping the surface of the cleaning plate 11, the control cylinder 10 controls the mounting tube 21 to slide down. At this time, the transmission bevel block 35 slides under the top pressure, and drives the closing plug 37 to slide between the connecting pipe 32 and the pressure relief port 33 through the transmission plate 22 and the transmission rod 24. At this time, the storage box 31 exhausts the air into the storage tube 18, realizing the coordinated knocking and sliding down.

[0103] After scraping and cleaning the plate 11, the control cylinder 10 controls the mounting tube 21 to slide up until the mounting tube 21 is separated from the transmission bevel block 35. At this time, the transmission bevel block 35 is reset by elastic force. At this time, the closing plug 37 slides between the connecting pipe 32 and the adapter nozzle 34, and the gas inside the storage box 31 is discharged from the pressure relief port 33.
