Die-castings are widely used in automobiles, 3C products, communication infrastructure equipment, home appliances, medical equipment and other industries. A complete vehicle has a large number of parts, and most of the parts are castings. Castings are smelted liquid metals that are injected into pre-prepared molds by pouring, injection, suction or other casting methods. After cooling and subsequent processing such as polishing, the resulting objects have a certain shape, size and performance. This process usually includes the steps of smelting metal, preparing molds, pouring metal, cooling and solidification, and subsequent processing.

[0003] During the production period, the temperature of the casting is relatively high. At this time, the casting must be cooled. During the cooling of the casting and placing it in the water tank, the slag bags, flash and smaller debris on the surface of the casting will fall into the water tank. Larger attachments will be filtered out by the screening net, but smaller debris may leak out.

With the sprinkler head 20, the purification shell 13 and the unblocking shell 15 are connected with the rotating column 21, and the bearing blade 22 is fixedly connected to the rotating column 21. The rotating column 21 is connected to the on-off opening part of the unblocking shell 15, so that the on-off opening part is adjusted according to the flow speed of the circulating water in the purification shell 13. When the water flow is slow, the on-off button 32 on the attraction member 31 is pressed. The attraction member 31 is installed in the unblocking shell 15. The attraction member 31 is made of an iron core and a matching conductive winding. After conduction, it can interact with the magnet and the metal. A plurality of high and low displacement exchangeable screening net units are displaceably installed in the purification shell 13 and the unblocking shell 15, and a rod body 38 is installed on the screening net unit, and a limiting chamber 39 and a linkage part 40 are installed on the rod body 38. There is a The constraint unit with pressure release effect constrains the screening unit through the constraint unit, and releases the constraint unit through the cooperation of the suction piece 31 and the linkage part 40, so that the screening unit can achieve the effect of replacing the screening. The product can be clamped by a robot and immersed in cooling water for cooling. After cooling is achieved, the robot moves the workpiece to the blowing area, and the air source connected by the connecting pipe head 1110 is blown out from the air outlet channel 1111. During the cooling period, the product slag bags, flash, etc. remaining on the casting fall and accumulate in the screening shell 119, but some small debris will leak out through the leakage hole, which will cause debris to exist in the cooling water in the box 11. During the cooling of the cooling water in the box 11, the cooling water is processed by the processing unit to ensure cleanliness.

[0038] The purification shell 13 is installed at the input port of the water pump 112. The purification shell 13 is a rectangular structure. The flow shell 15 is installed under the purification shell 13. The baffle 16 is assembled through fasteners. The discharge chamber 17 is located under the baffle 16. The cleaning unit 18 is assembled on the side wall of the flow shell 15 and is located on the opposite side of the baffle 16. The input channel 19 can be input through an external water source.

[0039] In this solution, a purification shell 13 is installed on the water pump. The purification shell 13 is located between the water pump 112 and the input hole 14. The circulating water flows backward after the debris is screened out by the purification shell 13, and a flow-through shell 15 is installed on the purification shell 13. The screening net unit used in the purification shell 13 can be stored in the flow-through shell 15, and the external water source is input to the cleaning unit 18 through the input channel 19. The sprinkler head 20 on the cleaning unit 18 is used to clean, and the mixed liquid mixed with debris is discharged from the discharge chamber 17, and the shield plate 16 can be easily disassembled, and the components in the flow-through shell 15 can be repaired.

[0040] The rotating column 21 is vertically arranged, connected to the bottom of the purification shell 13 and the top of the unblocking shell 15 and penetrates the purification shell 13 and the unblocking shell 15 , and the penetrated connection area is leakproof, and the bearing blade 22 is located on the side wall of the input hole 14 .

[0041] The screening net unit installed in the purification shell 13 can screen out debris in the circulating water. However, the continuous processing of the circulating water during operation may cause the screening net to be blocked. Therefore, a flow speed measuring part is installed in the purification shell 13. During the period when the circulating water moves into the purification shell 13, the traction force generated by the displacement is applied to the supporting blade 22, thereby pulling the rotating column 21 to rotate. The rotating column 21 is connected to the on-off opening part, so that the flow speed can be reflected in the on-off opening part. During the period when the screening net unit is blocked and hinders the circulation attenuation of the circulating water, the on-off opening part is used to drive the start of the suction member 31, thereby achieving the operation of replacing the screening net unit.

[0042] The on-off opening part includes a displacement platform 24 fixedly connected to the rotating column 21, a spiral beryllium copper wire 25 is fixedly connected to the displacement platform 24, a linkage rod 26 is fixedly connected to the spiral beryllium copper wire 25, and the on-off opening part includes a guide rod 27 fixedly connected to the flow shell 15, a spiral beryllium copper wire 28 is installed on the guide rod 27, a switching rod 29 is fixedly connected to the spiral beryllium copper wire 28, and a supporting platform 30 is fixedly connected to the switching rod 29.

[0043] During the rotation of the rotating column 21, several displacement platforms 24 are pulled to rotate together. The generated inertia can pull the linkage rod 26 to suppress the tension of the spiral beryllium copper wire 25 to slide toward the side. The linkage rod 26 will press on the supporting platform 30 to allow the switching rod 29 to slide on the guide rod 27. If the rotating column 21 rotates normally, the switching rod 29 can move away from the on-off button 32 of the attraction member 31. However, during the period when the flow of the rotating column 21 is not smooth and the speed is attenuated, the inertia becomes weak, and the external force applied by the linkage rod 26 to the switching rod 29 is reduced. As a result, the switching rod 29 is applied to the on-off button 32, causing the attraction member 31 to have a short-term attraction.

[0044] The displacement platform 24 is circularly arranged on the rotating column 21 and is equipped with more than 6 pieces. A spiral beryllium copper wire 25 is arranged in the displacement groove of the displacement platform 24. The linkage rod 26 is slidably arranged in the displacement groove. The guide rod 27 is connected to the inner wall of the unblocking shell 15 at a ninety-degree angle. The switching rod 29 is slidably arranged on the guide rod 27. One end of the switching rod 29 is located at the side wall of the on-off button 32. The supporting platform 30 and the linkage rod 26 are closely connected.

[0045] The screening net unit includes a screening part 33 slidably arranged between the purification shell 13 and the flow shell 15, on which a screening net 34 and a rubber sheet 35 are arranged, on which a spiral beryllium copper wire 36 and a magnet platform 37 are fixedly connected, and on the outer side of the magnet platform 37 a spiral beryllium copper wire 5 is arranged.

[0046] Since the screening net unit is composed of a plurality of screening parts 33, it can be operated in steps. Only one screening net 34 is used all the time, and there is a screening effect in the purification shell 13. However, when the screening net 34 is blocked, the blocked screening net 34 can be replaced and adjusted to operate with a smooth screening net 34. Moreover, this adjustment behavior can be operated actively, and the attraction of the suction member 31 is used as the power.

[0047] The rubber sheet 35 is installed around the screening part 33. The screening part 33 is a rectangular structure. The rubber sheet 35 is attached and connected to the purification shell 13. The rubber sheet 35 is a ring structure installed in the central area of ​​the screening part 33. The spiral beryllium copper wire 36 is connected between the screening part 33 and the bottom of the unblocking shell 15. The magnet platform 37 is located below the screening part 33 and above the attracting member 31. There are more than 4 screening parts 33, which are divided into head units and terminal units installed on both sides, and central units between the head units and the terminal units. There are more than 2 central units.

[0048] In the screening net unit in the present scheme, the operation of the screening part 33 is switched in sequence, from the head unit to the center unit, then to the end unit, and then back to the head unit. According to the operation of the head unit, when the screening net 34 of the head unit is not smooth, the attraction generated by the attraction member 31 is applied to the magnet platform 37, so that the head unit can fall quickly, and the constraint unit at the tail of the head unit can be constrained on one side, and the linkage part 40 can be used on the other side to release the constraint unit at the tail of the center unit, so that the center unit can be used like the head unit, and the center unit and the end unit can be used in turn.

[0049] The rod body 38 is vertically arranged below the screening part 33, the limiting cavity 39 is located at the side wall of the rod body 38, one end of the linkage part 40 is arranged facing the tail, and the constraint unit includes a center platform 41 and a side platform 42 fixedly connected in the unblocking shell 15, and a stop cavity is arranged in the center platform 41 and the side platform 42, and a spiral beryllium copper wire 43 is installed in the stop cavity, and a constraint platform 44 is fixedly connected to the spiral beryllium copper wire 43, and a wire body 45 is fixedly connected to the constraint platform 44, and the wire body 45 is fixedly connected to the moving platform 46, and the moving platform 46 is located in the moving cavity 47.

[0050] The constraint unit can constrain the rod body 38 and the screening part 33, and can also be released through the pressure of the linkage part 40. The clean screening part 33 in the unobstructed shell 15 also bears the effect of attraction, but because of its insufficient displacement length, it is impossible to cause the adaptive constraint unit to be released. Therefore, during the replacement of the unobstructed screening part 33, only the adjacent subsequent screening part 33 can be pulled out, and considering the long distance between the head unit and the terminal unit, the main part of the constraint unit is divided into a center platform 41 and a side platform 42. The distance of the side platform 42 is longer, the release area is at the tail of the terminal unit, and the constraint area is at the tail of the head unit.

[0051] The centering platform 41 is located between the head unit and the centering unit, the centering unit and the centering unit, and the centering unit and the terminal unit. The constraint platform 44 on the centering platform 41 is used to constrain the rod body 38 of the centering unit and the terminal unit. The side platform 42 is concave in structure and is located between the terminal unit and the head unit. The constraint platform 44 on the side platform 42 is used to constrain the rod body 38 of the head unit. The motion cavity 47 is installed on the centering platform 41 and the side platform 42. The motion platform 46 in the centering platform 41 is located at the tail end of the linkage part 40 on the head unit and the centering unit, and the motion platform 46 in the side platform 42 is located at the tail end of the linkage part 40 on the terminal unit.

[0052] In the constraint unit, the constraint platform 44 is displaced by pulling the spiral beryllium copper wire 43, and is connected to the limiting cavity 39 on the rod body 38, so as to achieve the purpose of restraining the screening part 33. During the period when the screening part 33 is rapidly dropped and constrained, pressure can be applied to the moving platform 46 through the linkage part 40, thereby allowing the moving platform 46 to move to the rear, and the constraint platform 44 is pulled by the wire body 45 to release the adapted screening part 33, so as to achieve the purpose of replacement.

[0053] The unblocking shell 15 is fixedly connected with an assembly plate 48, and a sliding reset rod 49 is fixedly connected to the assembly plate 48. A cleaning broom 50 is slidingly arranged on the sliding reset rod 49, and the cleaning broom 50 is located at the side of the screening net unit.

[0054] In this solution, not only the debris on the blocked screening net 34 is treated with an external water source, but also the debris is cleaned by a cleaning broom 50 on the mounting plate 48. The treatment is performed during the up and down displacement of the screening net 34, and the cleaning broom 50 has an active dodging effect, which can prevent the screening net 34 from being damaged.

[0055] The specific implementation method is as follows: the product is clamped by a robot and immersed in cooling water for cooling. After cooling is completed, the robot moves the workpiece to the blowing area, and the air source connected to the connecting pipe head 1110 is blown out from the air outlet channel 1111. During the cooling period, the slag bags and flash of the products remaining on the casting fall and accumulate in the screening shell 119, but some small debris will leak out through the water leakage hole, so that the cooling water in the box body 11 will have debris. During the cooling of the cooling water in the box body 11, the cooling water is processed by the treatment unit to ensure cleanliness. A purification shell 13 is installed on the pump. The purification shell 13 is between the pump 112 and the input hole 14. The circulating water flows backward after screening the debris through the purification shell 13, and a smooth The through shell 15 can store the screening net unit used in the purification shell 13 into the unblocked shell 15, and input external water source into the cleaning unit 18 through the input channel 19, and use the sprinkler head 20 on the cleaning unit 18 to clean, and the mixed liquid with debris is discharged from the discharge chamber 17, and the baffle 16 can be easily disassembled, and the components in the unblocked shell 15 can be repaired. During the operation, the continuous treatment of circulating water may cause the screening net to be blocked. Therefore, a flow speed measuring part is installed in the purification shell 13. During the period when the circulating water moves to the purification shell 13, the traction force generated by the displacement will be applied to the bearing blade 22, thereby pulling the rotating column 21 to rotate, and the rotating column 21 is connected to the on-off opening part, so that the flow speed can be reflected in the on-off opening part. The phenomenon of unblocked flow hinders the circulation of circulating water. During the attenuation period, the on-off opening part is used to drive the start of the attraction member 31, thereby achieving the operation of replacing the screening unit. During the rotation of the rotating column 21, a number of displacement platforms 24 are pulled to rotate together. The generated inertia can pull the linkage rod 26 to suppress the tension of the spiral beryllium copper wire 25 to slide to the side. The linkage rod 26 will press on the supporting platform 30 to allow the replacement rod 29 to slide on the guide rod 27. If the rotating column 21 rotates normally, the replacement rod 29 can deviate from the on-off button 32 of the attraction member 31. However, during the attenuation period of the unblocked flow of the rotating column 21, the inertia weakens, and the external force applied by the linkage rod 26 to the replacement rod 29 is reduced, so that the replacement rod 29 is applied to the on-off button 32, so that the attraction member 31 has a short-term attraction. Since the screening net unit is composed of several screening parts 33, it can be operated in steps. Only one screening net 34 is used all the time, and there is a screening effect in the purification shell 13. However, when the screening net 34 is blocked, the blocked screening net 34 can be replaced, and it can be adjusted to operate with a smooth screening net 34, and this adjustment behavior can be operated actively, using the attraction of the suction member 31 as the power. In the screening net unit in this scheme, the operation of the screening part 33 is switched in sequence, from the head unit to the middle unit, then to the end unit, and then back to the head unit. According to the operation of the head unit as a reference, when the screening net 34 of the head unit is blocked, the attraction generated by the suction member 31 is applied to the magnet platform 37, so that the head unit can fall quickly.On one hand, the constraint unit at the tail of the head unit is constrained, and on the other hand, the linkage part 40 can be used to release the constraint unit at the tail of the center unit, so that the center unit can be used in the same way as the head unit, and the center unit and the end unit can be used in turn. The constraint unit can constrain the rod 38 and the screening part 33, and can also be released through the pressure of the linkage part 40. The clean screening part 33 in the unblocked shell 15 also bears the effect of attraction, but because of its insufficient displacement length, it cannot cause the release of the constraint unit it is adapted to. Therefore, during the replacement of the unblocked screening part 33, only the adjacent subsequent screening part 33 can be pulled out, and considering that the distance between the head unit and the end unit is relatively long, the main part of the constraint unit is divided into a center platform 41 and a side platform 42. The distance between the side platform 42 is relatively long, and the release area is at the end. The tail of the unit, the constraint area is located at the tail of the head unit. In the constraint unit, the constraint platform 44 is pulled by the spiral beryllium copper wire 43 to move, and is connected to the limiting cavity 39 on the rod body 38 to achieve the purpose of restraining the screening part 33. During the rapid fall of the screening part 33, when it is restrained, it can be pressed on the moving platform 46 through the linkage part 40, thereby allowing the moving platform 46 to move to the tail, and the constraint platform 44 is pulled by the wire body 45 to release the adapted screening part 33 to achieve the purpose of replacement. In this scheme, not only the external water source is used to treat the debris on the unsmooth screening net 34, but also the cleaning broom 50 on the assembly plate 48 is used to clean it. The treatment is performed during the high and low displacement of the screening net 34, and the cleaning broom 50 has the effect of actively avoiding, which can prevent the screening net 34 from being damaged.
