DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1: Reference Figure 1-8The valve seat forging forming die for a fracturing pump shown in the figure includes a lower die seat 1 and an upper die seat 2. A core 3 is provided in the middle of the lower die seat 1. During processing, the lower die seat 1 and the core 3 are at the same horizontal height to facilitate processing. After processing, in order to facilitate the removal of the forged parts inside the core 3, a hydraulic mechanism is provided on the bottom surface of the lower die seat 1 to control the lifting and lowering of the lower die seat 1, thereby exposing the core 3. The core 3 is a split design, which is convenient for removing the forged parts inside the core 3.

[0028] In this embodiment, the mold core 3 is divided into four parts, and a demoulding mechanism for controlling the outward movement of the mold core 3 is provided on the bottom plate 4 provided below the mold core 3. The overall power source of the demoulding mechanism is driven by a transmission mechanism. A groove is provided on the top surface of the bottom plate 4, and a multi-layer partition is provided inside the groove. Limiting grooves 41 are provided at the edges of the partition and the bottom plate 4. Four groups of limiting grooves 41 are provided on the bottom plate 4. Moving rods 7 are slidably connected in the limiting grooves 41. Teeth are provided on the outer wall of each group of moving rods 7, and a connecting gear 5 is provided below the moving rod 7. The connecting gear 5 is a ring gear. Therefore, in order to connect the connecting gears The wheel 5 is connected to the moving rod 7, so a transmission gear 6 connecting the two is provided between the two. Therefore, when the transmission mechanism drives one set of transmission gears 6 to work, the transmission gear 6 drives the ring gear to rotate, and then the rotating ring gear drives the other three sets of transmission gears 6 to work, so that the moving rod 7 located in the limiting groove 41 moves outward, and the connecting rod 71 provided on the top surface of the moving rod 7 cooperates with the connecting groove 31 at the bottom of the quarter core 3 to control the four sets of cores 3 to move outward, expand the radius of the core 3, release the limit on the forging parts, facilitate removal, and improve the forging efficiency.

[0029] A fixing seat 13 is provided on the top surface of the middle part of the bottom plate 4. The fixing seat 13 is transparent from top to bottom and has a threaded section inside. The bottom surface of the bottom plate 4 is rotatably connected to a lifting gear 10. A cross hole is provided in the middle of the lifting gear 10, and a hole is provided in the middle of the bottom plate 4. The positions of the hole and the cross hole correspond to each other. A lifting rod 12 is slidably connected in the cross hole. In order to prevent the lifting rod 12 from falling off, a thread is provided on the outer wall of the lifting rod 12, and the thread is matched with the threaded section. The lifting gear 10 plays a role of rotating and twisting the lifting rod 12. With the cooperation of the threaded section and the thread, the lifting rod 12 is controlled to rise and fall in the fixing seat 13. The positioning rod on the top surface of the fixing seat 13 and the positioning groove on the lifting block 14 are matched. Therefore, with the cooperation of the above structure, the lifting rod 12 lifts the lifting block 14, and the lifting block 14 lifts the forging piece to assist in forging and removing the piece.

[0030] The driving gear 9 of the transmission mechanism is rotatably connected to the bottom surface of the base plate 4, and is meshed with the lifting gear 10, and is also meshed with the transfer gear 8. The transfer gear 8 is coaxially designed with the transmission gear 6 to achieve the purpose of transfer, so that when the driving gear 9 is driven to rotate by the driving motor 11, the demoulding mechanism and the lifting mechanism are started synchronously.

[0031] The working principle of the utility model is as follows: the equipment is started, the upper die seat 2 is controlled to move downward, and the forging part located inside the die core 3 is forged, and then the upper die seat 2 is restored to its original position, and then the hydraulic mechanism is started, and the hydraulic mechanism drives the lower die seat 1 to move downward, thereby exposing the die core 3, and then the drive motor 11 on the mounting table is started, and the drive motor 11 drives the drive gear 9 connected to the bottom of the bottom plate 4 to rotate, and the demoulding mechanism and the lifting mechanism are driven to work through the drive gear 9.

[0032] Demolding mechanism: The driving gear 9 drives one of the transmission gears 6 designed coaxially with the transfer gear 8 to rotate through the transfer gear 8 meshing with it. The rotating transmission gear 6 rotates in the groove of the base plate 4. The teeth on the transmission gear 6 mesh with the connecting gear 5 in the base plate 4 and mesh with the moving rod 7 above the connecting gear 5, thereby driving the connecting gear 5 to rotate. The rotating connecting gear 5 drives the other groups of transmission gears 6 to rotate, so that the remaining three groups of moving rods 7 move outward. The moving rod 7 moves in the limiting groove 41, and cooperates with the connecting groove 31 on the bottom surface of the mold core 3 through the connecting rod 71 provided on the top surface, so as to control the outward diffusion of the mold core 3 and expand the radius, which is convenient for the staff to take the material.

[0033] Lifting mechanism: The driving gear 9 rotates to drive the lifting gear 10 meshing with it to rotate on the bottom surface of the bottom plate 4. The hole of the lifting gear 10 and the cross-section of the lifting rod 12 are both cross-shaped, so the lifting gear 10 here imitates the action of a human hand to rotate the lifting rod 12. In order to prevent the lifting rod 12 from falling, the lifting rod 12 passes through the bottom plate 4 and cooperates with the threaded section inside the fixing seat 13 to achieve a threaded connection to prevent it from falling. In the process of lifting the lifting rod 12, the lifting block 14 on the top of the fixing seat 13 is lifted up, and the demolding mechanism is cooperated to assist in the removal of the forged parts.

[0035] Components not described in detail herein are prior art.
