[0006] Preferably, the casting assembly includes an upper mold, a lower mold is arranged at the bottom of the upper mold, an electromagnet is arranged at the top of the upper mold, air rods are fixedly connected to both ends of the electromagnet, a feeding port is opened at one end of the upper mold, and a wind box is fixedly connected to the other end of the upper mold.

[0007] Preferably, one end of the bottom plate is provided with a movable groove, and the other end of the bottom plate is fixedly connected with a fixed groove.

[0008] Preferably, one end of the lower mold is fixedly connected to the side surface of the connecting plate, and the other end of the lower mold is movably connected to the inside of the fixed groove.

[0009] Preferably, an air duct is fixedly connected to the side surface of the air box.

[0010] Preferably, a stepping motor is fixedly connected to the side surface of the fixed block.

[0011] Preferably, a fixing member and a second fixing member are respectively fixedly connected to both sides of the movable groove. The rotating member is fixedly connected to the top of the fixing member. The connecting plate penetrates through the second fixing member and is fixedly connected to the driven gear.

[0012] The utility model provides a multi-functional control valve body casting for hydraulic components. Compared with the prior art, the following beneficial effects are achieved:

[0013] 1. For the multi-functional control valve body casting of hydraulic components, the stepping motor drives the rotating member to rotate. When the rotating member rotates, it drives the externally sleeved sliding rod to swing left and right. Since the sector gear fixedly connected to the side surface of the sliding rod can drive the externally meshed driven gear to rotate while swinging with the sliding rod, the connecting plate fixedly connected to the side surface of the driven gear will swing simultaneously, causing the metal liquid injected inside to shake, enter the corner and curved surface cavities, and at the same time defoaming the metal liquid inside to avoid the generation of air holes during casting.

[0014] 2. For the multi-functional control valve body casting of hydraulic components, through the fixing effect of the connecting plate and the fixed groove, after the lower mold and the feeding port are combined, they can be driven by the connecting plate to swing simultaneously. After the casting is completed, the electromagnet adsorbs on the top of the feeding port to lift the feeding port. At the same time, the air box arranged at one end of the upper mold collects the harmful gases through the air duct to avoid the harmful gases from overflowing and affecting the health of employees.

[0021] Please refer to Figures 1-4 The present invention provides a technical solution: a multi-functional control valve body casting for hydraulic components. It includes a casting component 1, and a swing component 2 is arranged at one end of the casting component 1. The swing component 2 includes a bottom plate 21. One end of the bottom plate 21 is fixedly connected with a fixed block 22, and the fixed block 22 is used to fix the fixed rod 24 and the stepping motor 27. One side of the top of the fixed block 22 is fixedly connected with a fixed rod 24. One end of the fixed rod 24 is movably connected with a slide rod 25. A sector gear 26 is fixedly connected to the side of the slide rod 25. The bottom of the sector gear 26 meshes with a driven gear 212. A connecting plate 211 is fixedly connected to the side of the driven gear 212. A rotating piece 29 is slidably connected inside the slide rod 25. When the rotating piece 29 rotates, it slides inside the slide rod 25, causing the slide rod 25 to swing. The sector gear 26 can swing along with the slide rod 25 to drive the driven gear 212 engaged at the bottom to rotate back and forth, so that the connecting plate 211 fixedly connected to the side of the driven gear 212 can drive the lower die 12 to swing.

[0022] Please refer to Figures 1-2, the casting component 1 includes an upper mold 11. A lower mold 12 is provided at the bottom of the upper mold 11. An electromagnet 14 is provided at the top of the upper mold 11. The electromagnet 14 is a device that generates an electromagnetic field once powered on. When a power voltage is applied across the two ends of the coil of the electromagnet 14, a current flows through the coil. The current as the excitation current of the coil generates a magnetic field, which magnetizes the iron core and makes it magnetic. Two air rods 15 are fixedly connected to both ends of the electromagnet 14. An inlet 13 is provided at one end of the upper mold 11. Molten metal is injected into the interior through the inlet 13. A bellows 16 is fixedly connected to the other end of the upper mold 11. An air duct 17 is fixedly connected to the side of the bellows 16. During demolding, the bellows 16 can inhale harmful gases in the air into the interior through the air duct 17.

[0023] Please refer to Figure 1 , 3 -4. An activity slot 213 is provided at one end of the bottom plate 21. The activity slot 213 is used to provide space for the swing of the sliding rod 25. A fixed slot 23 is fixedly connected to the other end of the bottom plate 21. The fixed slot 23 is used to support the lower mold 12. The circular arc setting enables the lower mold 12 to rotate inside. One end of the lower mold 12 is fixedly connected to the side of the connecting plate 211. The other end of the lower mold 12 is movably connected to the interior of the fixed slot 23. A stepping motor 27 is fixedly connected to the side of the fixed block 22. A fixing member 28 and a second fixing member 210 are respectively fixedly connected to both sides of the activity slot 213. The fixing member 28 and the second fixing member 210 can fix the stepping motor 27 and the connecting plate 211. A rotating member 29 is fixedly connected to the top of the fixing member 28. The connecting plate 211 passes through the second fixing member 210 and is fixedly connected to the driven gear 212.

[0024] During use, first, molten metal is injected into the interiors of the upper mold 11 and the lower mold 12 through the inlet 13. The stepping motor 27 drives the rotating member 29 to rotate. When the rotating member 29 rotates, it drives the sliding rod 25 sleeved outside to swing left and right. Since the sector gear 26 fixedly connected to the side of the sliding rod 25 can make the driven gear 212 meshed outside rotate while following the swing of the sliding rod 25, the connecting plate 211 fixed to the side of the driven gear 212 will swing simultaneously, causing the molten metal injected inside to shake, enter the corners and curved surface cavities, and at the same time defoam the interior of the molten metal to avoid the generation of air holes during casting. At the same time, after the casting is completed, the electromagnet 14 adsorbs on the top of the inlet 13 to lift the inlet 13. At the same time, the bellows 16 provided at one end of the upper mold 11 collects harmful gases in the interior through the air duct 17, avoiding the harmful gases from overflowing and affecting the health of employees.
