Technical Field

[0001] This utility model belongs to the field of plunger pump ball joint technology, specifically relating to a molding device for high-precision ball joint machining of plunger pumps. Background Technology

[0002] Compression molding is a key process in abrasive mold manufacturing. The process involves filling a mold cavity with a mixture of abrasive and binder (such as resin or ceramic), then applying pressure to the material through an upper punch to compress and shape it within the mold. Finally, pressure is maintained and the mold is demolded to obtain a mold blank with a specific shape, density, and strength. Existing compression molding equipment typically includes a frame, a lower worktable, an upper pressure plate, a mold, and a pressurizing system. The upper pressure plate is driven downwards by the pressurizing system (usually a hydraulic cylinder) to apply pressure to the material within the mold.

[0016] Please see Figure 1-7 The present invention provides a technical solution: a molding device for high-precision ball joint machining of a plunger pump, comprising a metal powder molding machine 1, a housing 2 and a support cover 22.

[0017] It should be added that the metal powder molding press 1 is an existing technology.

The electric cylinder 1 10 and the electric cylinder 3 12 are driven synchronously, while the electric cylinder 2 11 is driven independently.

[0021] The bottoms of electric cylinder 10, electric cylinder 21, and electric cylinder 312 are all fixedly connected to the base plate 4.

[0022] The base 5 is fixedly connected to the base plate 4. Three fixing plates 6 and the motor 7 are fixedly connected to the top of the base 5. The inner side of the fixing plate 6 is fixedly connected to the lower outer side of the motor 7, making the motor 7 more secure.

[0023] The output end of motor 7 is fixedly connected to fixing block 8, which is located inside hole 24. Fixing block 8 is fixedly connected to turntable 9, which is slidably connected to the top of support cover 22.

[0024] The bearing is connected to the fixing block 2 13 at the center of the upper part of the turntable 9. Four lower mold frames 18 are fixedly connected to the upper part of the turntable 9 and are evenly distributed on the turntable 9 and surround the fixing block 2 13. Four holes 5 26 and four sets of arc grooves 15 are evenly opened on the turntable 9, with each set consisting of two arc grooves 15.

[0025] The platform 3 is fixedly connected to the second fixing block 13, which is connected to the top bearing of the turntable 9.

[0026] A circular groove 14 is provided under the table surface 3. The fixing block 2 13 is located at the center of the circular groove 14. A through hole 4 25 is provided above the table surface 3, and the hole 4 25 is inside the circular groove 14. The upper end of the lower mold frame 18 is inside the circular groove 14, and the inner diameter of the lower mold frame 18 is the same as the inner diameter of the hole 4 25.

[0027] The lower mold frame 18 is fixedly connected to the center position of the style block 19. The style block 19 has a hole 27 in the middle, which is consistent with the inner diameter of hole 26. Hole 26 corresponds to hole 27. Each set of arc grooves 15 surrounds the style block 19.

[0028] The output end of electric cylinder 10 is fixedly connected to the left side of fixed plate 2 17, and the output end of electric cylinder 3 12 is fixedly connected to the right side of fixed plate 2 17. A hole 21 is opened in the middle of fixed plate 2 17. Two arc-shaped top plates 16 are fixedly connected to fixed plate 2 17.

[0030] Working principle: Because there are different models of plunger pumps, the models of ball joints also differ. The teeth inside the ball joint have different angles and numbers, so the mold needs to be replaced. Electric cylinder 10 and electric cylinder 3 12 drive downwards synchronously, causing the fixed plate 2 17 to move downwards. The fixed plate 2 17 drives the arc-shaped top plate 16 to move downwards until the top of the arc-shaped top plate 16 is lower than the top of the support cover 22. Electric cylinder 2 11 drives downwards, so that the top of the locking post 20 is lower than the top of the support cover 22.

[0031] Motor 7 starts working, and the output end of motor 7 drives the fixed block 8 to rotate. The fixed block 8 drives the turntable 9 to rotate, and the turntable 9 drives the upper lower mold frame 18 and the style block 19 to rotate. When the required style block 19 rotates 90°, motor 7 stops working.

[0032] Driven by electric cylinder 211, the output end of electric cylinder 211 moves upward, driving the positioning post 20 to move upward, passing through hole 526 to hole 627, until the positioning post 20 is flush with the top surface of table 3. Electric cylinder 10 and electric cylinder 312 are driven synchronously. The output ends of electric cylinder 10 and electric cylinder 312 move upward, driving the fixing plate 217 to move upward. The fixing plate 217 drives the arc-shaped top plate 16 to move upward until the top of the arc-shaped top plate 16 is flush with the top of the turntable 9.

[0033] When the metal powder molding machine 1 starts working, the powder filling device fills the lower mold frame 18 with metal powder. At the same time, the upper mold frame moves downward, and the electric cylinder 2 11 continues to drive upward, so that the locking post 20 is inserted into the upper mold frame. When the ball joint is pressed, the upper mold frame moves upward, and the electric cylinder 2 11 continues to drive downward, so that the locking post 20 is flush with the top surface of the table 3. Then, the electric cylinder 1 10 and the electric cylinder 3 12 drive synchronously, and the fixing plate 2 17 moves upward. The fixing plate 2 17 drives the arc-shaped top plate 16 upward until the top of the arc-shaped top plate 16 is flush with the top of the table 3. At the same time, the powder filling device pushes the ball joint mold that has been pressed forward. At the same time, the ball joint mold is pushed open, and the electric cylinder 1 10 and the electric cylinder 3 12 drive synchronously, and the fixing plate 2 17 moves downward. The fixing plate 2 17 drives the arc-shaped top plate 16 downward until the top of the arc-shaped top plate 16 is flush with the top of the turntable 9.
