Description

Technical Field

[0001] This invention relates to the field of casting island technology, specifically to a molding sand surface processing device based on an electrically automated intelligent casting island. Background Technology

[0002] A casting island is an intelligent production unit in the industrial manufacturing field. It specifically refers to a closed production module that integrates die casting machines, automated equipment, and intelligent control systems. It is mainly used for the efficient forming of metal castings (such as aluminum alloys, magnesium alloys, etc.). It consists of a large die casting machine, a robotic arm, a mold temperature control system, real-time monitoring equipment, etc. It achieves data interconnection and process optimization through the Internet of Things. The casting island manufactures sand molds by mixing molding sand with a curing agent, and then sprays a release agent on the surface of the sand mold before casting.

[0003] However, when sand casting is performed on the casting island, excess binder or release agent will flow along the edges of the sand mold when it is sprayed and adhered to the sand mold. This results in uneven distribution of the binder or release agent, which affects the strength of the sand mold or the demolding of the workpiece. Therefore, it does not meet the existing requirements. To address this, we propose a sand surface processing device based on an electrically automated intelligent casting island. Summary of the Invention

The spraying structure is located above the smooth transfer table. The position of the spraying structure is controlled by the spraying robot arm, and the spraying structure is used to spray the surface of the sand mold.

The delivery pump is in contact with the liquid inside the storage tank through a hose, and the output end of the delivery pump is connected to the nozzle through a hose.

[0010] Preferably, both ends of the double-headed electric telescopic rod are fixed with side baffles, and one side of the double-headed electric telescopic rod is fixed with multiple guide support rods. A moving direction baffle is slidably provided on the outer side of the guide support rod. Both the side baffles and the moving direction baffles are provided with recycling grooves inside. A first recycling pipe is fixedly inserted through the outer side of the side baffles, and a second recycling pipe is fixedly inserted through the outer side of the moving direction baffles.

[0011] Preferably, a recovery pump is also fixed on the upper surface of the storage tank. The output end of the recovery pump is connected to the inside of the storage tank through a hose. A third recovery pipe is fixed to the input end of the recovery pump. A three-way valve is connected to the end of the third recovery pipe. The end of the second recovery pipe away from the moving direction baffle has two branches. The branches of the second recovery pipe and the end of the first recovery pipe are connected to the three-way valve.

[0012] Preferably, the moving structure includes a fixed motor, which is fixed to the ground. The output shaft of the fixed motor outputs upward and is fixed with a rotating disk. Four rotationally symmetrical rotating contact rods are fixed on the outer side of the rotating disk.

[0013] Preferably, the outer side of the end of the rotating contact rod away from the rotating disk is covered with a protective rubber sleeve, and the corners of the protective rubber sleeve are rounded and the surface is smooth.

[0014] Preferably, the roller conveyor table includes a frame, a gearbox and a motor support plate are fixed on one side of the frame, a conveying motor is fixed on the surface of the motor support plate, the output shaft of the conveying motor is connected to the input end of the gearbox, a plurality of conveying rollers and curing strips are linearly arrayed on the inner side of the frame, the conveying rollers and curing strips are spaced apart from each other, and the output end of the gearbox passes through the frame and is connected to the conveying rollers.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention utilizes side baffles and moving direction baffles to shield the sand mold from the side. During the spraying of curing agent and release agent, the curing agent and release agent that exceed the edge of the sand mold flow along the inner surface of the side baffles and moving direction baffles into the recovery tank, thereby preventing the curing agent or release agent from flowing along the edge of the sand mold during spraying, ensuring that the thickness of the curing agent and release agent at the edge of the sand mold is uniform, and not affecting the subsequent demolding and installation of the sand mold.

[0019] 2. This invention recovers the curing agent and release agent collected inside the recovery tank through the first recovery pipe and the second recovery pipe, and then transports the recovered curing agent and release agent back into the storage tank, thereby avoiding raw material waste and reducing production costs;

[0020] 3. In this invention, the curing agent and the release agent are transported to the liquid storage tank through the connecting liquid channel via a straight pipe. The curing agent and the release agent are absorbed by the sponge coating jacket through the liquid holes and are evenly applied to the bottom of the sand mold during the transfer of the sand mold by the transfer roller.

[0021] 4. This invention uses a drying lamp to cure the curing agent and release agent applied to the bottom of the sand mold, while using a heat insulation pad to block the heat transmitted to the side by the drying lamp, thus preventing the heat from the drying lamp from curing the curing agent and release agent absorbed by the sponge coating.

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] like Figure 1 As shown, the molding sand surface processing equipment based on the electrical automation intelligent casting island includes a fixed base 1, on which a smooth transfer table 2 is embedded. The surface of the smooth transfer table 2 is smooth and burr-free. Roller conveyor tables 5 are fixed at both ends of the fixed base 1. The roller conveyor tables 5 are used to transport the sand mold and perform bottom spraying operations.

[0032] like Figures 3 to 5 As shown, the roller conveyor table 5 includes a frame 501. A gearbox 502 and a motor support plate 504 are fixed on one side of the frame 501. A conveyor motor 503 is fixed on the surface of the motor support plate 504. The output shaft of the conveyor motor 503 is connected to the input end of the gearbox 502. Multiple transfer rollers 506 and curing strips 507 are linearly arrayed on the inner side of the frame 501. The transfer rollers 506 and curing strips 507 are spaced apart from each other. The output end of the gearbox 502 passes through the frame 501 and is connected to the transfer rollers 506. The transfer rollers 506 are driven to rotate in the same direction by the conveyor motor 503 and the gearbox 502, thereby conveying the sand mold.

[0033] The transfer roller 506 includes a drive shaft 5061. One end of the drive shaft 5061 is provided with a docking liquid channel 5062. A straight conveying pipe 505 is rotatably inserted into the inner side of the docking liquid channel 5062. Both ends of the drive shaft 5061 are rotatably connected to the frame 501 through roller bearings. An outer cylinder 5063 is fixed to the outer side of the drive shaft 5061. A liquid storage tank 5066 is provided between the outer cylinder 5063 and the drive shaft 5061. A sponge coating jacket 5065 is sleeved on the outer side of the outer cylinder 5063. Multiple liquid holes 5064 are provided on the outer surface of the outer cylinder 5063. The curing agent and the release agent are transferred to the liquid storage tank 5066 through the docking liquid channel 5062 via the straight conveying pipe 505. The curing agent and the release agent are absorbed by the sponge coating jacket 5065 through the liquid holes 5064 and are evenly coated on the bottom of the sand mold during the transfer of the sand mold by the transfer roller 506.

[0034] The curing strip 507 includes a protective housing 5071. Two symmetrically distributed heat insulation pads 5072 are bonded to the inner side of the protective housing 5071. A drying lamp tube 5073 is also fixed to the inner side of the protective housing 5071. The curing agent and release agent applied to the bottom of the sand mold are cured by the drying lamp tube 5073.

[0035] like Figure 1 , Figure 6 and Figure 7 As shown, a fixed frame 3 is fixed above the two fixed seats 1, and a spraying robot arm 4 is fixed below the fixed frame 3. A spraying structure 7 is detachably installed at the bottom of the spraying robot arm 4. The spraying structure 7 is located above the smooth transfer table 2. The position of the spraying structure 7 is controlled by the spraying robot arm 4, and the spraying structure 7 is used to spray the sand mold surface.

[0036] The spraying structure 7 includes a rotating disk 701. A rotary motor is fixed inside the bottom of the spraying robotic arm 4. The output shaft of the rotary motor is fixedly connected to the rotating disk 701. A double-headed electric telescopic rod 702 is fixed to the bottom of the rotating disk 701. Two symmetrical storage tanks 709 are fixed to the upper surface of the double-headed electric telescopic rod 702. The storage tanks 709 store curing agent or release agent. A nozzle 708 is fixed to the middle of the bottom surface of the double-headed electric telescopic rod 702. A delivery pump 711 is fixed to the upper surface of the storage tanks 709. The delivery pump 711 is in contact with the liquid inside the storage tanks 709 through a hose. The output end of the delivery pump 711 is connected to the nozzle 708 through a hose. The curing agent or release agent is delivered through the delivery pump 711 and the hose and sprayed evenly through the nozzle 708.

[0037] Both ends of the double-headed electric telescopic rod 702 are fixed with side baffles 703. Multiple guide support rods 707 are fixed on one side of the double-headed electric telescopic rod 702. A moving direction baffle 705 is slidably provided on the outer side of the guide support rod 707. Both the side baffles 703 and the moving direction baffles 705 are provided with recycling grooves 712. A first recycling pipe 704 is fixed through the outer side of the side baffles 703, and a second recycling pipe 706 is fixed through the outer side of the moving direction baffles 705. The side baffles 703 and the moving direction baffles 705 are used to shield the side of the sand mold to prevent the curing agent or release agent from flowing along the edge of the sand mold when sprayed, and to ensure that the thickness of the curing agent and release agent at the edge of the sand mold is uniform.

[0038] A recovery pump 710 is also fixed on the upper surface of the storage tank 709. The output end of the recovery pump 710 is connected to the inside of the storage tank 709 through a hose. A third recovery pipe 713 is fixed to the input end of the recovery pump 710. A three-way valve is connected to the end of the third recovery pipe 713. The end of the second recovery pipe 706 away from the moving direction baffle 705 has two branches. The branches of the second recovery pipe 706 and the end of the first recovery pipe 704 are connected to the three-way valve. The curing agent and release agent collected inside the recovery tank 712 are recovered through the first recovery pipe 704 and the second recovery pipe 706, and the recovered curing agent and release agent are transported back to the inside of the storage tank 709 to avoid waste of raw materials.

[0039] like Figure 1 and Figure 2 As shown, each side of the fixed base 1 is provided with an independent moving structure 6, which pushes and moves the sand mold located on the surface of the smooth transfer table 2.

[0040] The moving structure 6 includes a fixed motor 601, which is fixed to the ground. The output shaft of the fixed motor 601 is upward and fixed to a rotating disk 602. Four rotationally symmetrical rotating contact rods 603 are fixed to the outside of the rotating disk 602. The outer side of the rotating contact rods 603 away from the rotating disk 602 is covered with a protective rubber sleeve 604. The corners of the protective rubber sleeve 604 are rounded and the surface is smooth. The rotating contact rods 603 and the protective rubber sleeve 604 are used to push and transfer the sand mold located on the surface of the smooth transfer table 2, and during the transfer process, it is ensured that the outer surface of the sand mold will not be damaged or scratched due to the contact of the protective rubber sleeve 604.

[0041] Working principle: After the sand mold is prepared, it is transferred to the surface of the roller conveyor table 5. The roller conveyor table 5 is used to transfer the sand mold to the surface of the smooth transfer table 2. During the transfer, the straight conveyor pipe 505 transmits the curing agent and release agent to the liquid storage tank 5066 through the docking liquid channel 5062. The curing agent and release agent are absorbed by the sponge coating jacket 5065 through the liquid hole 5064 and are evenly coated on the bottom of the sand mold during the transfer of the sand mold by the conveyor roller 506.

[0042] After the bottom of the sand mold is coated, the curing agent or release agent applied to the bottom of the sand mold is cured using the drying lamp tube 5073. Then the sand mold is transferred to the surface of the smooth transfer table 2. At this time, the spraying robot arm 4 drives the spraying structure 7 to move, so that the moving direction baffle 705 is in contact with the side of the sand mold facing the roller conveyor table 5. The double-headed electric telescopic rod 702 is powered on and drives the two side baffles 703 to be in contact with the side of the sand mold. After the side baffles 703 and the moving direction baffles 705 are in contact with the sand mold;

[0043] The delivery pump 711 extracts the curing agent or release agent from the storage tank 709 and sprays it evenly onto the surface of the sand mold through the nozzle 708. During the spraying process, the curing agent or release agent that exceeds the edge of the sand mold falls into the recovery tank 712 inside the side baffle 703 and the moving direction baffle 705 and is collected. As the nozzle 708 moves, the side baffle 703 moves in contact with the side of the sand mold. The moving side baffle 703 flattens the side of the sand mold, thereby preventing the curing agent or release agent from flowing along the edge of the sand mold during spraying, ensuring that the thickness of the curing agent and release agent at the edge of the sand mold is uniform and does not affect the subsequent demolding and installation of the sand mold.

[0044] After the sand mold surface treatment is completed, the spraying robot arm 4 drives the spraying structure 7 to reset as a whole. Then, the sand mold is transferred to another roller conveyor table 5 through the moving structure 6. The processed sand mold is then transported to the next process through this roller conveyor table 5. The remaining sand molds are then processed for automated production.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
