Description

Technical Field

[0001] The invention belongs to the technical field of pump cover processing equipment, and specifically relates to a casting molding device for producing an ultra-long self-priming pump cover. Background Art

[0002] An ultra-long self-priming pump refers to a pump that has self-priming ability and can operate under a long suction range. It can work normally under long suction range conditions. The general suction range can reach several meters to tens of meters. It is widely used in the petroleum, chemical, metallurgical and other industries to transport various liquids, including corrosive liquids. Ultra-long self-priming pumps are usually composed of pump casings, impellers, suction pipes, discharge pipes, mechanical seal components, pump shafts and pump covers. However, the pump cover is formed by a casting device during production, usually: Sand casting: using sand as the main material to prepare the casting mold; Lost foam casting: using foam plastic to make a pattern, and letting the foam pattern evaporate or disappear during the casting process to form a casting; Precision casting: also known as lost wax casting, by coating the wax mold with ceramic material and then dewaxing to form a casting mold; Metal mold casting: using metal materials (usually steel or cast iron) to make molds that can be used repeatedly; Pressure casting: injecting molten metal into a metal mold at high speed and high pressure; Centrifugal casting: by injecting molten metal into a high-speed rotating mold, the metal is filled into the mold and formed by centrifugal force; investment casting: a shell is formed by covering a pattern of sand and resin mixture, and then filled with metal for casting; continuous casting: molten metal is continuously poured into a water-cooled mold, rapidly cooled and solid castings are continuously pulled out; vacuum casting: casting is carried out in a vacuum environment to reduce pores and inclusions, and improve the quality and mechanical properties of castings; gypsum casting: casting is carried out using a gypsum mold.

[0003] The metal mold casting molding device used in the existing pump cover has a relatively simple structural design. Usually, the upper mold is connected to the hydraulic system, and the lower mold is on the processing table. During the production process, the staff manually operates the metal spoon to pour the aluminum liquid from the smelting furnace into the metal mold. After a period of cooling time, the upper mold is driven up by the hydraulic cylinder, and the staff removes the molded pump cover to complete the entire production process. Although the entire device can achieve semi-automatic production, it also has some shortcomings. First, the staff may be scalded by the high-temperature aluminum liquid due to manual loading. Second, each time the aluminum liquid needs to be cooled and formed before the next pump cover can be cast. The processing efficiency is low and mass production cannot be carried out. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a casting molding device for producing an ultra-long self-priming pump cover.

[0005] The technical solution adopted to solve the above technical problems is: a casting molding device for producing an ultra-long self-priming pump cover, comprising a feeding mechanism, an upper mold spraying mechanism is installed at the bottom center of the feeding mechanism, and a material transfer mechanism is arranged on one side of the rear end of the feeding mechanism; A first feeding mechanism is arranged between one side of the feeding mechanism and the material transfer mechanism, a lower mold spraying mechanism is arranged on one side of the material transfer mechanism, and a plurality of pump cover mold assemblies are arranged on the top of the material transfer mechanism; A pouring mechanism is provided on the other side of the material transfer mechanism, and a drainage mechanism is provided between the material transfer mechanism and the pouring mechanism; A material unloading mechanism is arranged at the rear end of the material transfer mechanism, a second material feeding mechanism is installed between the material transfer mechanism and the material unloading mechanism, the material loading mechanism has the same structure as the material unloading mechanism, and the first material feeding mechanism has the same structure as the second material feeding mechanism.

[0006] Furthermore, the feeding mechanism includes a support frame, a feeding conveyor belt is installed on the support frame, and a plurality of first positioning grooves are formed on the feeding conveyor belt.

[0007] Through the above technical solution, the staff places the upper mold body into the first positioning groove, automatically transports the upper mold body through the feeding conveyor belt, and then sends it to the transfer mechanism through the first feeding mechanism.

[0008] Furthermore, the upper mold spraying mechanism includes a first mounting frame fixedly connected to the center of the support frame, a first material storage box is fixedly connected to one side of the top of the first mounting frame, a first liquid pump is fixedly connected to the other side of the top of the first mounting frame, a straight nozzle is fixedly connected to the support frame and located at the center of the feeding conveyor belt, a plurality of first nozzles are fixedly connected to the top of the outer wall of the straight nozzle, a first connecting pipe is fixedly connected between the first liquid pump and the first material storage box, a second connecting pipe is fixedly connected between the first liquid pump and the straight nozzle, and a first laser sensor is fixedly installed on the support frame and located on the other side of the straight nozzle.

[0009] Through the above technical solution, when the upper mold body is transported by the feeding conveyor belt, when the first laser sensor detects the upper mold body, it transmits information to the first liquid pump, and the first liquid pump starts to work. The first liquid pump extracts the demoulding liquid in the first storage box through the first connecting pipe, and transports it to the straight nozzle through the second connecting pipe, and then sprays the bottom of the upper mold body through multiple first nozzles, so that the pump cover formed later can be better removed from the pump cover mold assembly, thereby improving production efficiency.

[0010] Furthermore, the material transfer mechanism includes a first base arranged on one side of the rear end of the support frame, the top center of the first base is rotatably connected to the first rotating shaft, the top of the first rotating shaft is fixedly connected to a transfer disk, a plurality of second positioning grooves distributed in an annular manner are opened on the top of the transfer disk, a first divider is fixedly installed on the top front end of the first base, a first motor is fixedly installed on one side of the first divider, the output shaft of the first motor is connected to the input shaft of the first divider, the outer wall of the output shaft of the first divider is fixedly connected to the first gear, the outer wall of the first rotating shaft is fixedly connected to the first gear ring, the first gear is meshed with the first gear ring, a third laser sensor is fixedly installed on one side of the top of the transfer disk, a fourth laser sensor is fixedly installed on the other side of the top of the transfer disk, and a fifth laser sensor is fixedly installed on the top rear end of the transfer disk.

[0011] Through the above technical solution, the staff can place the upper mold body in the second positioning groove of the rotating disk and start the first motor. The first motor drives the first divider output shaft to rotate, and then drives the first gear to rotate. The rotation of the first gear drives the first gear ring to rotate, and then drives the first rotating shaft and the rotating disk to rotate, thereby realizing the circular rotation of multiple upper mold bodies, which is convenient for the subsequent lower mold spraying mechanism to automatically spray it, and also convenient for the subsequent pouring mechanism to automatically pour aluminum liquid.

[0012] Furthermore, the first feeding mechanism includes a first fixed frame arranged on one side of the supporting frame, the top of the first fixed frame is fixedly connected to a slide rail, the inner wall of the slide rail is fixedly connected to a rack, a slide seat is slidably connected to the slide rail, the top of the slide seat is fixedly connected to a second motor, the outer wall of the second motor output shaft is fixedly connected to a second gear, the second gear is meshed with the rack, one side of the slide seat is fixedly connected to a first hydraulic cylinder, the bottom end of the first hydraulic cylinder piston is fixedly connected to an electromagnet, and a second laser sensor is fixedly installed at the center of one side of the first fixed frame.

[0013] Through the above technical solution, the sprayed upper mold body continues to be transported through the feeding conveyor belt. At this time, the second laser sensor detects the upper mold body and transmits information to the second motor and the first hydraulic cylinder. The output shaft of the second motor rotates to drive the second gear to rotate, so that the second gear rotates on the rack, and drives the slide to slide on the slide rail. When the slide is close to the position of the upper mold body, the first hydraulic cylinder drives the electromagnet to move downward through the piston, so that the electromagnet attracts the upper mold body, and then transports it to the top of the rotating disk through the slide, close to the position directly above the adjacent lower mold body, and resets the piston of the first hydraulic cylinder to drive the upper mold body to fit with the lower mold body to complete the assembly.

[0014] Furthermore, the lower mold spraying mechanism includes a second fixed frame arranged on one side of the first base, the top of the second fixed frame is fixedly connected to an annular nozzle, the bottom end of the outer wall of the annular nozzle is fixedly connected to a plurality of second nozzles, the top of the center side of the second fixed frame is fixedly connected to a second material storage box, a second liquid pump is fixedly connected to the other side of the second fixed frame close to the second material storage box, a third connecting pipe is fixedly connected between the second liquid pump and the second material storage box, and a fourth connecting pipe is fixedly connected between the second liquid pump and the annular nozzle.

[0015] Through the above technical solution, when the rotating material plate rotates, it drives multiple lower mold bodies to rotate. At this time, the third laser sensor detects the lower mold body and transmits the information to the second liquid pump. The second liquid pump starts to work. The second liquid pump extracts the demoulding liquid from the second storage box through the third connecting pipe, and transports it to the annular nozzle through the fourth connecting pipe. Then, the top of the lower mold body is sprayed through multiple second nozzles, so that the pump cover formed later can be better removed from the pump cover mold assembly, thereby improving production efficiency.

[0016] Furthermore, the pump cover mold assembly includes a lower mold body arranged in the second positioning groove, the top four corners of the lower mold body are fixedly connected with positioning heads, the first positioning groove is provided with an upper mold body, the top of the upper mold body is provided with a pouring port, and the bottom inner end surface of the upper mold body is provided with positioning holes at the four corners. In the assembled state, the plurality of positioning heads are respectively embedded in the corresponding positioning holes.

[0017] Through the above technical solution, the aluminum liquid flows into the molding grooves of the lower mold body and the upper mold body through the pouring port. During assembly, multiple positioning heads are inserted into the corresponding positioning holes, so that the rotating plate prevents the upper mold body from shifting when rotating, thereby improving the stability of the assembly of the lower mold body and the upper mold body and improving the casting quality of the pump cover.

[0018] Furthermore, the drainage mechanism includes a third fixing frame arranged on the other side of the first base, the top of the third fixing frame is fixedly connected with a concave drainage plate, and one side of the top of the concave drainage plate is fixedly connected with a drainage funnel.

[0019] Through the above technical solution, the aluminum liquid flows through the drainage funnel to the concave drainage plate, and then flows to the pouring port of the upper mold body through the concave drainage plate. The entire pouring process does not require manual operation by the staff, which improves the safety of the staff and improves production efficiency.

[0020] Furthermore, the pouring mechanism includes a second base arranged on the other side of the third fixed frame, the top center of the second base is rotatably connected to the second rotating shaft, the top of the second rotating shaft is fixedly connected to the chassis, the second divider is fixedly installed on the top front end of the second base, a third motor is fixedly installed on one side of the second divider, the output shaft of the third motor is connected to the input shaft of the second divider, the outer wall of the output shaft of the second divider is fixedly connected to the third gear, the outer wall of the second rotating shaft is fixedly connected to the second gear ring, the third gear is meshed with the second gear ring, a plurality of annularly distributed second mounting frames are fixedly connected to the top of the chassis, a plurality of second mounting frames are rotatably connected to connecting frames, a plurality of connecting frames are fixedly installed with furnaces, a plurality of furnaces are fixedly connected with discharge nozzles on the tops, a plurality of second mounting frames are respectively installed with second hydraulic cylinders between the corresponding connecting frames, the bottom ends of the plurality of second hydraulic cylinders are rotatably connected to the corresponding second mounting frames, and the top ends of the plurality of second hydraulic cylinder pistons are rotatably connected to the corresponding connecting frames.

[0021] Through the above technical scheme, when the rotating material plate drives the assembled pump cover mold assembly for transportation, the fourth laser sensor detects the pump cover mold assembly and transmits the information to the second hydraulic cylinder, and the second hydraulic cylinder starts to work. The second hydraulic cylinder pushes the connecting frame through the piston, so that the connecting frame flips upward, so that the connecting frame drives the furnace to flip upward, and the discharge nozzle rotates accordingly, so that the discharge nozzle flips to the top of the drainage funnel. Due to gravity, the aluminum liquid in the furnace is poured into the drainage funnel. When the aluminum liquid in the furnace is poured, the third motor can be started, and the third motor drives the second divider to operate, so that the output shaft of the second divider drives the third gear, so that the third gear drives the second gear ring to rotate, so that the second gear ring drives the second rotating shaft and the chassis to rotate, and then drives multiple furnaces to rotate, so that the adjacent furnaces rotate to one side of the drainage funnel, and continue to pour aluminum liquid into the pump cover mold assembly. Since one furnace is working and pouring, the other two furnaces are loaded and the aluminum blocks are melted, so that the entire casting equipment continues to produce pump covers without stopping operation, which greatly improves production efficiency.

[0022] The beneficial effects of the present invention are as follows: (1) The present invention designs a loading mechanism, a first feeding mechanism, a transfer mechanism, a unloading mechanism and a second feeding mechanism. The loading mechanism and the first feeding mechanism automatically transport the upper mold, and the transfer mechanism automatically transfers the lower mold.

After cooling and forming, the upper mold is automatically removed by the unloading mechanism and the second feeding mechanism, which is convenient for the staff to take the formed pump cover. The whole process is automated and has high production efficiency. (2) The present invention designs a drainage mechanism and a pouring mechanism. The pouring mechanism automatically pours molten aluminum into the pump cover mold assembly, and the three designed furnaces can be used in order without stopping to melt aluminum blocks, thereby improving production efficiency. The whole process does not require manual pouring, thereby improving the safety of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

The third motor 805 drives the second divider 804 to operate, so that the output shaft of the second divider 804 drives the third gear 806, so that the third gear 806 drives the second ring gear 807 to rotate, and the second ring gear 807 drives the second rotating shaft 802 and the chassis 803 to rotate, thereby driving multiple furnaces 810 to rotate, so that the adjacent furnaces 810 rotate to one side of the drainage funnel 703, and continue to pour aluminum liquid into the pump cover mold assembly 6. When one furnace 810 is working and pouring, the other two furnaces 810 are loading and melting the aluminum blocks, so that the entire casting equipment continues to produce pump covers without stopping operations, which greatly improves production efficiency.

[0034] The working principle of this embodiment is as follows: the staff places the upper mold body 603 into the first positioning groove 103, and automatically transports the upper mold body 603 through the feeding conveyor 102, and at the same time places the upper mold body 603 in the second positioning groove 304 of the rotating disk 303. When the upper mold body 603 is transported by the feeding conveyor 102, the first laser sensor 11 detects the upper mold body 603 and transmits the information to the first liquid pump 203, and the first liquid pump 203 starts to work. The first liquid pump 203 extracts the demoulding liquid in the first storage box 202 through the first connecting pipe 206, and transports it to the straight nozzle 204 through the second connecting pipe 207, and then sprays the bottom of the upper mold body 603 through multiple first nozzles 205; At the same time, the first motor 306 drives the output shaft of the first divider 305 to rotate, and then drives the first gear 307 to rotate. The rotation of the first gear 307 drives the first gear ring 308 to rotate, and then drives the first rotating shaft 302 and the rotating material plate 303 to rotate, so as to realize the circular rotation of multiple upper mold bodies 603. At this time, the third laser sensor 13 detects the lower mold body 601 and transmits the information to the second liquid pump 505. The second liquid pump 505 starts to work. The second liquid pump 505 extracts the demoulding liquid from the second storage box 504 through the third connecting pipe 506, and transports it to the annular nozzle 502 through the fourth connecting pipe 507, and then sprays the top of the lower mold body 601 through multiple second nozzles 503; After the spraying of the upper mold body 603 and the lower mold body 601 is completed, the upper mold body 603 continues to be transported by the feeding conveyor 102. At this time, the second laser sensor 12 detects the upper mold body 603 and transmits the information to the second motor 405 and the first hydraulic cylinder 407. The output shaft of the second motor 405 rotates to drive the second gear 406 to rotate, so that the second gear 406 rotates on the rack 403, and then drives the slide 404 to slide on the slide rail 402. When sliding close to the position of the upper mold body 603, the first hydraulic cylinder 407 drives the electromagnet 408 to move downward through the piston, so that the electromagnet 408 absorbs the upper mold body 603, and then transports it to the top of the rotating disk 303 through the slide 404, close to the position just above the adjacent lower mold body 601, and resets the piston of the first hydraulic cylinder 407. At this time, multiple positioning heads 602 are inserted into the corresponding positioning holes 605 to complete the assembly of the upper mold body 603 and the lower mold body 601; After the assembly is completed, the rotating material plate 303 continues to rotate. At this time, the fourth laser sensor 14 detects the pump cover mold assembly 6 and transmits the information to the second hydraulic cylinder 812. The second hydraulic cylinder 812 starts to work. The second hydraulic cylinder 812 pushes the connecting frame 809 through the piston, so that the connecting frame 809 flips upward, so that the connecting frame 809 drives the furnace 810 to flip upward, and at the same time, the discharge nozzle 811 rotates accordingly, so that the discharge nozzle 811 flips to the top of the drainage funnel 703. Due to gravity, the aluminum liquid in the furnace 810 is poured into the drainage funnel 703, and the aluminum liquid flows through the drainage funnel 703 to the concave drainage plate 702, and then through the concave drainage funnel 703. The guide plate 702 flows into the pouring port 604 of the upper mold body 603 to complete the pouring of the pump cover mold assembly 6. When the aluminum liquid in the melting furnace 810 is poured, the third motor 805 can be started, and the third motor 805 drives the second divider 804 to operate, so that the output shaft of the second divider 804 drives the third gear 806, so that the third gear 806 drives the second gear ring 807 to rotate, so that the second gear ring 807 drives the second rotating shaft 802 and the chassis 803 to rotate, and then drives multiple furnaces 810 to rotate, so that the adjacent furnaces 810 rotate to one side of the drainage funnel 703, and continue to pour aluminum liquid into the pump cover mold assembly 6; The rotating disk 303 continues to rotate, and at the same time, the aluminum liquid in the pump cover mold assembly 6 is cooled and formed. At this time, the fifth laser sensor 15 detects the pump cover mold assembly 6 and transmits the information to the second feeding mechanism 10. The second feeding mechanism 10 transfers the upper mold body 603 to the unloading mechanism 9, and the staff removes the pump cover formed on the lower mold body 601, completing the entire production process.
