Description

Technical Field

[0001] The invention relates to the technical field of stainless steel part casting, in particular to a stainless steel part casting molding machine. Background Art

[0002] Casting is a relatively early metal heat processing technology mastered by humans, with a history of about 6,000 years. China entered the heyday of bronze castings between 1700 BC and 1000 BC, and the technology had reached a very high level. Casting is a method of pouring liquid metal into a casting cavity that is adapted to the shape of the part, and then cooling and solidifying it to obtain a part or blank.

[0003] Existing stainless steel parts are generally made by casting, such as pins.

[0004] The prior art has the following deficiencies:

[0005] 1. Bubbles and impurities are likely to exist inside the molten steel. If they are not removed in time, they will affect the microstructure of the product, thereby reducing the casting quality and affecting the product quality.

[0006] 2. After the existing stainless steel pin is cast, it is necessary to manually knock the casting scraps at the water inlet to loosen the casting and make it fall from the cavity, which reduces the demoulding efficiency and increases the labor workload of workers.

[0007] 3. Since there are pin holes on the outer wall of the stainless steel pin shaft, directly pulling the product out of the mold cavity after the pin shaft is cast can easily damage the mold and casting. Summary of the invention

[0026] Beneficial effects of the present invention:

[0027] 1. The present invention designs a degassing mechanism, a receiving pipe, a storage tank, an extrusion assembly, a transmission assembly and a plurality of atomizing nozzles, so that a degassing agent can be sprayed into the interior of a plurality of storage tanks through the plurality of atomizing nozzles before the molten steel is injected into the mold, thereby removing bubbles and impurities in the molten steel before casting the pin shaft, making the organizational structure of the casting more uniform, thereby improving the casting quality of the parts.

[0028] 2. The present invention realizes the linkage operation of the degassing mechanism and the pouring mechanism by designing a transmission component, that is, the degassing agent can be sprayed on the inside of several receiving tanks while the molten steel is stirred, so that the added degassing agent and the molten steel can be quickly and fully integrated, the removal rate of bubbles and impurities in the molten steel can be accelerated, and the degassing efficiency can be improved.

[0029] 3. The present invention designs a knocking mechanism, i.e., a reciprocating swinging assembly, a plurality of rocker arms and a plurality of knocking blocks. After the casting is completed and the lower mold is lowered and separated from the pin shaft, the scraps of the stainless steel pin shaft formed in the water nozzle can be automatically knocked by the plurality of knocking blocks, so that the stainless steel pin shaft in the upper mold cavity is vibrated and falls from the mold cavity of the upper mold to the top of the plurality of ejector pins. This not only eliminates the need for manual knocking of the casting, thereby improving the demolding efficiency, but also reduces the workload and labor intensity of the workers, thereby helping to save labor costs.

[0030] 4. The present invention, through the design of a knocking mechanism and an automatic demoulding mechanism, can first drive the lower mold to descend and disengage from the pin after the pin is cast. During the disengagement process, a number of ejectors continue to support the outer wall of the pin. After the lower mold is lowered into place, the rotating assembly and four buffer springs drive the several ejectors to slowly descend. At the same time, the knocking block knocks the scraps of the stainless steel pin formed in the water inlet, and cooperates with a number of slowly descending ejectors to slowly separate the pin from the upper mold, avoiding the existing method of removing the casting from the mold by pulling and tugging, which is beneficial to protecting the mold and the casting and avoiding losses. At the same time, the pin is supported by a number of ejectors, which can reduce the contact area with the pin, facilitate rapid heat dissipation of the pin, and thus improve the cooling efficiency.

[0031] 5. The present invention designs the plug plate and the extrusion assembly. Each time the extrusion rod squeezes the degassing agent toward the end close to the liquid outlet, the push plate follows the extrusion rod to slide toward the end close to the delivery pipe, thereby preventing the degassing agent in the storage tank from continuously falling from the discharge pipe into the water receiving pipe and causing waste. The through hole ensures that the receiving pipe keeps consistent with the external air pressure each time the extrusion rod is reset to the right, thereby reducing the resistance encountered by the extrusion rod when it is reset. Each time the extrusion rod is reset to the right, the degassing agent in the storage tank automatically flows from the discharge pipe into the receiving pipe to pre-store the degassing agent, thereby achieving an automatic filling effect. There is no need to manually fill the receiving pipe with degassing agent, thereby realizing automatic delivery of the degassing agent.

[0032] 6. The present invention can cast multiple pins at the same time by designing a molding mechanism, namely two telescopic components, a plurality of upper molds and a plurality of lower molds, so that a plurality of pins can be cast at one time, thereby realizing batch processing of pins, which is beneficial to expanding production and increasing corporate profits.

Each time the extrusion rod 423 squeezes the deaerator toward the end close to the liquid outlet, the push plate 601 follows the extrusion rod 423 to slide toward the end close to the delivery pipe 400, thereby preventing the deaerator in the storage tank 41 from continuously falling from the discharge pipe 410 into the water receiving pipe and causing waste. The through hole 428 ensures that the receiving tube 40 is consistent with the external air pressure each time the extrusion rod 423 is reset to the right and slides to the right, thereby reducing the resistance encountered by the extrusion rod 423 when it is reset. Each time the extrusion rod 423 is reset to the right and slides to the right, the deaerator in the storage tank 41 automatically flows from the discharge pipe 410 into the interior of the receiving tube 40 to pre-store the deaerator to facilitate the next air delivery operation.

[0088] Reference Figures 1 to 11 As shown, each telescopic assembly 60 includes a cylinder 600, a push plate 601 and two limit rods 602, the two limit rods 602 are fixedly arranged on the top of the base 1, the cylinder 600 is vertically arranged on the top of the base 1, the push plate 601 is slidably arranged on the outer walls of the two limit rods 602, the output end of the cylinder 600 is fixedly connected to the bottom of the push plate 601, the cylinder 600 is electrically connected to the controller, when the molten steel in the receiving tank 31 is degassed, the cylinder 600 is started by the controller, so that its output end extends upward, because its output end is fixedly connected to the push plate 601, the push plate 601 is slidably connected to the two limit rods 602, the side walls of the plurality of lower molds 62 are fixedly connected to the push plate 601, and the plurality of lower molds 62 are fixedly connected through a plurality of second connecting rods, and then cooperate with another telescopic assembly 60 to drive the plurality of lower molds 62 and the plurality of upper molds 61 to close.

[0089] Reference Figures 1 to 11As shown, the rotating assembly 71 includes a second motor 710, a synchronous belt 711, two synchronous wheels 712 and four cams 713. A vertical plate is fixedly arranged on the top of the base 1. The second motor 710 is inserted on the outer wall of the vertical plate. Two second hinge shafts are symmetrically arranged on the top of the base 1. Every two cams 713 are fixed on one second hinge shaft. The output end of the second motor 710 is fixedly connected to one end of one of the second hinge shafts. Four rollers 700 are rotatably arranged on the lifting plate 70. The outer wall of each roller 700 is The outer wall of a cam 713 is in conflict with each other. Each synchronous wheel 712 is fixed on a second hinge shaft. The synchronous belt 711 is sleeved between the two synchronous wheels 712. Two mounting blocks are fixedly provided on the top of the base 1. Two buffer springs 701 are fixedly provided between the top of each mounting block and one end of the bottom of the lifting plate 70. The second motor 710 is electrically connected to the controller. When the casting of several stainless steel pin shafts 8 is completed, the output ends of the two cylinders 600 are driven by the controller to shrink, so that the two push plates 601 slide down vertically, thereby driving several lower molds 62 to descend, that is, to disengage from several upper molds 61, and also to disengage from the outer wall of the lower half of several stainless steel pin shafts 8. Then the second motor 710 is started by the controller to rotate its output end. Since the output end of the second motor 710 is fixedly connected to one of the second hinge shafts, each two cams 713 are rotatably connected to the base 1 through a second hinge shaft. Each synchronous wheel 712 is fixedly connected to a second hinge shaft. The two synchronous wheels 712 are sleeved by the synchronous belt 711. In the initial state, the protrusion of each cam 713 is in conflict with the outer wall of a roller 700, so that when the four cams 713 rotate, the protrusions of the four cams 713 no longer conflict with the four rollers 700, thereby causing the lifting plate 70 lifted by the four cams 713 to drop vertically, and the two buffer springs 701 have a buffering effect, ensuring that the lifting plate 70 drives a plurality of ejector pins 72 to drop slowly. At this time, due to the water inlet 610, the upper half of the stainless steel pin 8 will not automatically separate from the cavity 620 of the upper mold 61.

[0090] Reference Figures 1 to 11As shown, the reciprocating swing assembly 50 includes an electric push rod 500, a second rack 501, a cylindrical gear 502, a second connecting rod 503 and a slide bar 504, wherein a mounting plate is fixedly provided on the top of one of the vertical plates, a slideway is fixedly provided on the outer wall of the mounting plate, the second rack 501 is slidably provided on the slideway, a third hinge shaft is rotatably provided on the top of one of the upper molds 61, the cylindrical gear 502 is fixedly provided on one end of the third hinge shaft, the cylindrical gear 502 is meshedly connected with the second rack 501, the second connecting rod 503 is fixedly provided on the other end of the third hinge shaft, the slide bar 504 is hingedly provided on the end of the second connecting rod 503 away from the third hinge shaft, and a sliding bar 504 is provided on the outer wall of one of the swing rods 51 close to the cylindrical gear 502 The electric push rod 500 is electrically connected to the controller. Due to the water inlet 610, the upper half of the stainless steel pin shaft 8 will not automatically separate from the cavity 620 of the upper mold 61. Therefore, when the plurality of ejector pins 72 slowly descend, the electric push rod 500 is started by the controller, so that its output end extends downward. Since its output end is fixedly connected to the second rack 501, the cylindrical gear 502 is fixedly connected to one end of the third hinge shaft, the second connecting rod 503 is fixedly connected to the other end of the third hinge shaft, and the cylindrical gear 502 is meshed with the second rack 501, thereby driving the second connecting rod 503 to rotate clockwise with the third hinge shaft as the center. A sliding groove for the slide bar 504 to slide is provided on the outer wall of the swing rod 51. The slide bar 504 is hinged to the end of the second connecting rod 503 away from the third hinge axis, and then the slide bar 504 drives one of the swing rods 51 close to the cylindrical gear 502 to swing clockwise with the rotating rod 611 as the center. Since the other two swing rods 51 are fixedly connected to the rotating rod 611, the three swing rods 51 are driven to rotate clockwise with the rotating rod 611 as the center, and further drive a plurality of knocking blocks 52 to knock the leftovers of the stainless steel pin shaft 8 formed in the water outlet 610, so that the stainless steel pin shaft 8 in the cavity 620 of the upper mold 61 is vibrated and falls from the cavity 620 of the upper mold 61 to the top of a plurality of ejector pins 72, each ejector pin 72. The tops of 72 are designed to fit the arc structure of the stainless steel pin 8, which can facilitate several ejector pins 72 to receive the fallen stainless steel pin 8, prevent the product from falling to the ground, play a fall-proof effect, and avoid losses. At the same time, the arc structure of the stainless steel pin 8 designed to fit the top of each ejector pin 72 is also flush with the inner wall of the cavity 620 of the lower mold 62, and will not affect the normal casting of the pin. Here, it should be noted that when several ejector pins 72 initially descend, the knocking block 52 starts to knock the stainless steel pin 8 scraps formed in the water outlet 610, which can ensure that the pin separated from the cavity 620 of the upper mold 61 falls into the top of the ejector pin 72 within the shortest distance of the descent of several ejector pins 72, thereby improving the stability of material discharge.

[0091] Reference Figures 1 to 11As shown, a drain pipe 311 is fixedly provided at the bottom of each receiving tank 31, and a solenoid valve 312 is fixedly provided on the outer wall of each drain pipe 311. Three liquid feeding grooves 20 are evenly spaced on the top of the mounting platform 2, and the top of each liquid feeding groove 20 is located below a drain pipe 311. The bottom of each liquid feeding groove 20 faces a water outlet 610. The solenoid valve 312 is electrically connected to the controller. When a plurality of lower molds 62 and a plurality of upper molds 61 are tightened, the solenoid valve 312 is activated by the controller, so that the drain pipe 311 is opened. Since three liquid feeding grooves 20 are evenly spaced on the top of the mounting platform 2, and the top of each liquid feeding groove 20 is located below a drain pipe 311, the bottom of each liquid feeding groove 20 faces a water outlet 610, and the solenoid valve 312 is electrically connected to the controller. When a plurality of lower molds 62 and a plurality of upper molds 61 are tightened, the solenoid valve 312 is activated by the controller, so that the drain pipe 311 is opened. Below the tube 311, the bottom of each liquid feeding groove 20 faces a water inlet 610, so that the degassed molten steel flows into between a plurality of upper molds 61 and a plurality of lower molds 62 through the inclined liquid feeding groove 20 until the cavities 620 of the two are filled, and then the casting of the parts is achieved by tightening the plurality of upper molds 61 and the plurality of lower molds 62. Here, it should be noted that the present application is mainly designed for the casting of stainless steel pin shafts 8, and the cavities 620 inside the plurality of upper molds 61 and the plurality of lower molds 62 are in the shape of fitting the outer wall of the stainless steel pin shaft 8, so the casting of the stainless steel pin shaft 8 can be automatically completed by tightening the plurality of upper molds 61 and the plurality of lower molds 62.

[0092] The working principle of the present invention is as follows: when the molten steel is poured into the interior of the receiving tank 31 from the liquid receiving port 310, the first motor 300 is started by the controller, so that its output end drives the first rotating shaft 301 to rotate. Since each worm 302 is meshedly connected with a worm wheel 303, several worms 302 are fixedly connected to the first rotating shaft 301, and each worm wheel 303 is fixedly connected to a stirring shaft 320, thereby driving several stirring shafts 320 to rotate counterclockwise.

[0093] When the stirring shaft 320 rotates counterclockwise, since the stirring shaft 320 is rotatably connected to the receiving tank 31 through the transverse plate, the plurality of stirring plates 321 are fixedly connected to the stirring shaft 320 through the pipe clamp, thereby driving the plurality of stirring plates 321 to rotate and stir the molten steel in the receiving tank.

[0094] While the stirring shaft 320 drives several stirring plates 321 to stir the molten steel in the liquid receiving tank, since the two sprockets 434 are respectively fixedly connected to the top of the second rotating shaft 431 and the top of one of the stirring shafts 320, the two sprockets 434 are sleeved by the chain 430, the first bevel gear 432 is fixedly connected to the bottom end of the second rotating shaft 431, and the second bevel gear 433 is fixedly connected to one end of the third rotating shaft, the first bevel gear 432 and the second bevel gear 433 are meshed and connected, thereby driving the third rotating shaft to rotate clockwise.

[0095] When the third shaft rotates clockwise, since the other end of the third shaft is fixedly connected to the toothless gear 420, the toothless gear 420 is meshed with the first rack 421, and the first rack 421 is slidably connected to the slide rail, thereby driving the first rack 421 to slide inside the slide rail toward the end away from the return spring 426. Since the second plug rod 425 is fixedly connected to the first rack 421, the second plug rod 425 is plugged into the avoidance gap at the bottom of the first connecting rod 422, so that when the first rack 421 drives the end to slide away from the return spring 426, the second plug rod 425 pushes the first connecting rod 422 to rotate counterclockwise with the first hinge axis as the center. The L-shaped block at one end of the extrusion rod 423 is fixedly connected, and the other end of the extrusion rod 423 is slidably connected to the receiving tube 40, so that the top end of the first connecting rod 422 is driven by the first plug rod 424 to push the extrusion rod 423 to slide inside the receiving tube 40 toward the end close to the liquid outlet, and the degassing agent pre-stored in the receiving tube 40 is squeezed into the inside of the delivery pipe 400, and then transported to the inside of several atomizing nozzles 44 by the diversion pipe 401. Since each atomizing nozzle 44 is facing a receiving tank 31, the degassing agent is sprayed on the inside of several receiving tanks 31 while stirring the molten steel, so that bubbles and impurities in the molten steel are removed before casting the parts, so that the organizational structure of the casting is more uniform, thereby improving the casting quality of the parts.

[0096] Each time the extrusion rod 423 squeezes the deaerator toward the end close to the liquid outlet, the push plate 601 follows the extrusion rod 423 to slide toward the end close to the delivery pipe 400, thereby preventing the deaerator in the storage tank 41 from continuously falling from the discharge pipe 410 into the water receiving pipe and causing waste. The through hole 428 ensures that the receiving pipe 40 is consistent with the external air pressure each time the extrusion rod 423 is reset to the right, thereby reducing the resistance encountered by the extrusion rod 423 when it is reset. Each time the extrusion rod 423 is reset to the right, the deaerator in the storage tank 41 automatically flows from the discharge pipe 410 into the interior of the receiving pipe 40, so as to pre-store the deaerator and facilitate the next air delivery operation.

[0097] When the degassing of the molten steel in the receiving tank 31 is completed, the cylinder 600 is started through the controller so that its output end extends upward. Since its output end is fixedly connected to the push plate 601, the push plate 601 is slidably connected to two limit rods 602, the side walls of several lower molds 62 are fixedly connected to the push plate 601, and several lower molds 62 are fixedly connected by several second connecting rods, and then cooperate with another telescopic component 60 to drive several lower molds 62 and several upper molds 61 to be tightened.

[0098] When several lower molds 62 are tightened with several upper molds 61, the solenoid valve 312 is started by the controller, so that the drain pipe 311 is opened. Since three liquid feeding grooves 20 are designed at equal intervals on the top of the mounting table 2, the top of each liquid feeding groove 20 is located below a drain pipe 311, and the bottom of each liquid feeding groove 20 faces a water outlet 610, so that the degassed molten steel flows into the several upper molds 61 and the several lower molds 62 through the inclined liquid feeding grooves 20 until the cavities 620 of the two are filled, and then the casting of the parts is achieved by tightening the several upper molds 61 and the several lower molds 62. Here, it should be noted that the present application is mainly designed for the casting of stainless steel pin shaft 8, and the cavity 620 inside the several upper molds 61 and the several lower molds 62 is a shape that fits the outer wall of the stainless steel pin shaft 8. Therefore, the casting of the stainless steel pin shaft 8 can be automatically completed by tightening the several upper molds 61 and the several lower molds 62.

[0099] When the casting of several stainless steel pins 8 is completed, the output ends of the two cylinders 600 are driven to contract through the controller, so that the two push plates 601 slide down vertically, thereby driving several lower molds 62 to descend, that is, to separate from several upper molds 61, and also to separate from the outer wall of the lower half of several stainless steel pins 8, and then the second motor 710 is started by the controller to rotate its output end. Since the output end of the second motor 710 is fixedly connected to one of the second hinge shafts, each of the two cams 713 is rotatably connected to the base 1 through a second hinge shaft, and each synchronous wheel 712 is connected to a second hinge shaft. The shafts are fixedly connected, and the two synchronous wheels 712 are sleeved by the synchronous belt 711. In the initial state, the protrusion of each cam 713 conflicts with the outer wall of a roller 700. Therefore, when the four cams 713 rotate, the protrusions of the four cams 713 no longer conflict with the four rollers 700, thereby causing the lifting plate 70 lifted by the four cams 713 to drop vertically. The two buffer springs 701 have a buffering effect, ensuring that the lifting plate 70 drives a number of ejector pins 72 to drop slowly. At this time, due to the water inlet 610, the upper half of the stainless steel pin 8 will not automatically detach from the cavity 620 of the upper mold 61.

[0100] The second link 503 is fixedly connected to the other end of the third hinge shaft, and the cylindrical gear 502 is meshed with the second rack 501, thereby driving the second link 503 to rotate clockwise around the third hinge shaft as the center. Since a groove for sliding the slide bar 504 is provided on the outer wall of one of the swing rods 51 close to the cylindrical gear 502, the slide bar 504 is hinged to the end of the second link 503 away from the third hinge shaft, and then the slide bar 504 drives one of the swing rods 51 close to the cylindrical gear 502 to swing clockwise around the rotating rod 611 as the center. Since the other two swing rods 51 are fixedly connected to the rotating rod 611, the three swing rods 51 are driven to rotate clockwise around the rotating rod 611 as the center, further driving the plurality of knockers 72 to rotate clockwise. The block 52 knocks the scraps of the stainless steel pin 8 formed in the sprue 610, so that the stainless steel pin 8 in the cavity 620 of the upper mold 61 is vibrated and falls from the cavity 620 of the upper mold 61 to the top of the plurality of ejector pins 72. The top of each ejector pin 72 is designed to fit the arc structure of the stainless steel pin 8, which can facilitate the plurality of ejector pins 72 to receive the fallen stainless steel pin 8, prevent the product from falling to the ground, play an anti-fall effect, and avoid losses. At the same time, each ejector pin The arc-shaped structure of the stainless steel pin 8 designed at the top of the needle 72 is also flush with the inner wall of the cavity 620 of the lower mold 62, and will not affect the normal casting of the pin. Here, it should be noted that when several ejector pins 72 initially descend, the knocking block 52 starts to knock the scraps of stainless steel pin 8 formed in the water outlet 610, which can ensure that the pin separated from the cavity 620 of the upper mold 61 falls into the top of the ejector pin 72 within the shortest distance of the descent of several ejector pins 72, thereby improving the stability of material discharge.
