[0034] Example
[0035] One embodiment of the present invention provides a high-speed powder molding machine, comprising a machine body, a power transmission unit, an upper punching unit, a feeding unit, a lower punching unit, a height detection unit, a pressure detection unit, and a control unit.
[0036] like Figure 1 As shown, the body includes an upper frame 11, a middle frame 12, a lower frame 13, and a cover 14.
[0037] The power transmission unit includes a motor 21 and a first transmission component.
[0038] The motor 21 is mounted on the frame, which is fixedly connected to the lower frame 13. In this embodiment, the motor 21 is a servo motor.
[0039] like Figure 2 , Figure 3 , Figure 4 As shown, the first transmission assembly includes a first transmission shaft 221, a first bevel gear 222, an upper punch eccentric wheel 223, and a lower punch cam 224. The first transmission shaft 221 is housed within the lower frame 13 and is parallel to the rotation shaft of the motor 21. The first bevel gear 222, the upper punch eccentric wheel 223, and the lower punch cam 224 are sequentially mounted on the first transmission shaft 221. The motor 21 drives the first transmission shaft 221 to rotate. This can be achieved using a belt or chain drive. When using a belt drive, a small pulley is mounted on the shaft of the motor 21, and a large pulley is mounted on the first transmission shaft 21. When using a chain drive, a small sprocket is mounted on the shaft of the motor 21, and a large sprocket is mounted on the first transmission shaft 21. (The belt or chain and the transmission wheel are not shown in the figure).
[0040] like Figure 3 As shown, the upper punch unit includes an upper crossbeam 31, a lower crossbeam 32, two rods 33, and an upper punch assembly. The upper crossbeam 31 and the lower crossbeam 32 are arranged parallel to each other and connected by the two rods 33. One end of each rod 33 is fixedly connected to both ends of the upper crossbeam 31, and the other end of each rod 33 is fixedly connected to both ends of the lower crossbeam 32. The upper crossbeam 31 is located on the upper part of the upper frame 11, and the lower crossbeam 32 is located inside the lower frame 13 and directly below the upper punch eccentric wheel 223. A spring return device is provided between the bottom of the lower crossbeam 32 and the frame housing. The upper punch assembly includes an upper punch head 34. 1. The upper punch shaft 342 is connected at one end to the middle of the upper crossbeam 31. The upper punch head 341 is installed at the other end of the upper punch shaft 342. The mold is set on the upper frame 11 and located directly below the upper punch head 341. During operation, when the upper punch eccentric wheel 223 rotates and contacts the lower crossbeam 32 and presses the lower crossbeam 32 down, the upper crossbeam 31 and the lower crossbeam 32 move downward together, thereby driving the upper punch head 341 to press down. When the upper punch eccentric wheel 223 rotates away from the lower crossbeam 32, the spring return device pushes the lower crossbeam 32 upward, thereby the upper punch head 341 also moves upward.
[0041] The feeding unit includes a second transmission assembly and a feeding assembly. The second transmission assembly includes a second transmission shaft 411, a second helical gear 412, and a second turntable 413. The second transmission shaft 411 is perpendicular to the first transmission shaft 221. One end of the second transmission shaft 411 is provided with a second bevel gear 412, which meshes with the first bevel gear 222. The other end of the second transmission shaft 411 is provided with a second turntable 413, and the top surface of the second turntable 413 is provided with a cam groove. The motor 21 drives the first bevel gear 222 on the first transmission shaft 221 to rotate. The first bevel gear 222 drives the second bevel gear 412 to rotate, and then drives the second turntable 413 to rotate via the second transmission shaft 411.
[0042] like Figure 5 As shown, the feeding assembly includes a movable block 421, two guide rods 422, a feeding box 423, a feeding box rail 424, and a connecting rod.

The two guide rods 422 are arranged in parallel, with one end connected to the feeding box rail 424 and the other end being a free end. The movable block 421 has through holes at both ends that match the guide rods 422, and a bearing at the bottom that matches the cam groove of the second turntable 413. The movable block 421 is fitted onto the two guide rods 422 and mounted on the second turntable 413. The movable block 421 is connected to the feeding box 423 via the connecting rod. The rotation of the second turntable 413 causes the movable block 421 to move on the guide rods 422, and also causes the feeding box 423 to move via the connecting rod.
[0043] like Figure 3 , Figure 4 As shown, the lower punch unit includes a lower punch frame and a lower punch assembly 52. The lower punch frame includes an upper top plate 511, a lower top plate 512 and a contact wheel 513. The upper top plate 511 and the lower top plate 512 are connected by a connecting rod. The contact wheel 513 is located at the bottom of the lower top plate 512 and above the lower punch cam 224, and contacts the lower punch cam 224. The lower punch assembly 52 is movably disposed within the upper frame 11, including a lower punch head 521 and a lower punch shaft 522. One end of the lower punch shaft 522 is provided with the lower punch head 521, and the other end is located directly above the upper top plate 511. The center lines of the upper punch shaft 342 and the lower punch shaft 522 are collinear. During operation, when the lower punch cam 224 rotates to contact the contact wheel 513 and lifts the lower top plate 512, the upper top plate 511 moves upward and drives the lower punch shaft 522 to move upward. When the lower punch cam 224 rotates to lower the lower top plate 512, the upper top plate 511 moves downward away from the lower punch shaft 522, and the lower punch shaft 522 moves downward.
[0044] like Figure 6 , Figure 7As shown, the height detection unit includes a height detection module, a fixed plate 62, and a detection baffle 63. The height detection module includes a contact rod 611 and a sensor 612.
