Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, and specifically relates to a friction plate stamping die that can quickly eject material. Background Technology

[0002] Friction plate stamping dies are special molds that use pressure provided by a press to apply external force to metal or non-metal sheets, causing them to undergo plastic deformation or separation, thereby obtaining friction plates with specific shapes, sizes and performance.

[0003] Currently, after the friction pads are processed, a drive device such as a cylinder or electric push rod is needed to move the push rod, which pushes the friction pads out of the lower mold base. This requires the installation of a drive device, which is costly. At the same time, due to the power output characteristics of the cylinder or electric push rod, it is difficult to control the speed precisely when driving the push rod to perform the unloading action. Often, the instantaneous movement speed is too fast, which can easily damage the mold. In addition, during the removal process after the friction pads are formed, the friction pads often stick to or get stuck in the mold cavity, resulting in insufficient material removal. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a friction plate stamping die that can quickly eject material, so as to solve the problems of the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A friction plate stamping die with rapid material ejection includes a base, a frame fixedly connected to one side of the base, a frame fixedly connected to one side of the frame, a cylinder fixedly connected to the top of the frame, a lifting plate fixedly connected to the output end of the cylinder, an upper die base fixedly connected to the bottom end of the lifting plate, a lower die base fixedly connected to one side of the top of the base, a guide groove provided inside the lower die base, one side of the guide groove being inclined, multiple air holes provided inside the guide groove, an air guiding cavity provided inside the lower die base, the air holes communicating with the air guiding cavity, an air pump fixedly connected to one side of the lower die base, the air pump's air delivery end communicating with the air guiding cavity, through rods fixedly connected to both sides of the bottom end of the lifting plate, through holes provided on both sides of the interior of the lower die base, a pusher assembly provided on one side of the lower die base, a transmission assembly provided on one side of the pusher assembly, and one side of the through rod sliding through the through hole and movably connected to the transmission assembly.

[0007] As a preferred technical solution, the pusher assembly includes a support block, which is slidably connected to the lower mold base. A shock-absorbing spring and a damper are fixedly connected to the top of the support block. The shock-absorbing spring is sleeved on the outside of the damper. A pusher block is fixedly connected to the common top of the shock-absorbing spring and the damper. The pusher block is movably connected inside the guide groove.

[0008] As a preferred technical solution, a fixed frame is fixedly connected to both sides of the lower mold base, a slider is slidably connected to the inner side of the fixed frame, the top end of the slider is fixedly connected to the bottom end of the support block, and pulleys are installed on both sides of the slider, with the pulleys slidably connected inside the fixed frame.

[0009] As a preferred technical solution, the transmission assembly includes a transmission plate, which is slidably connected inside the lower mold base. One side of the through rod is movably connected to one side of the transmission plate. A return spring is fixedly connected between the transmission plate and the lower mold base. Transmission blocks are fixedly connected to both sides of the transmission plate. A transmission rod is fixedly connected to the top of the transmission block. One side of the transmission rod is in movable contact with one side of the slider.

[0010] As a preferred technical solution, the transmission plate is fixedly connected to a guide rod on one side of the reset spring, and one side of the guide rod slides through the lower mold base.

[0011] In summary, the present invention has the following main advantages:

[0012] First, this utility model, by installing through rods on both sides of the lifting plate and opening through holes in the lower mold base, allows the through rods to pass through the through holes and contact the transmission component after the lifting plate drives the upper mold base to contact the lower mold base. The transmission component then enables the pushing component to work, causing the pushing block in the pushing component to be retracted into the lower mold base. After the friction plate is formed, the transmission component is no longer under pressure, and the pushing component resets, causing the pushing block to push the friction plate upward. This eliminates the need for external driving devices such as cylinders and electric push rods, which can significantly reduce the initial purchase cost of the mold, reduce production and operating costs, and also avoid impact force caused by excessive speed, thus preventing mold damage.

[0013] Secondly, in this utility model, when the pusher block pushes the formed friction plate upward, as the friction plate rises higher, the inclined inner wall of the guide groove can naturally guide the friction plate to disengage from the contact, reducing the probability of jamming and scratches caused by frictional resistance. During the unloading process, the air pump delivers high-pressure gas to the air guide cavity, which is then directionally sprayed into the guide groove through air holes distributed on the outside of the air guide cavity. The high-pressure airflow can form an air cushion between the friction plate and the guide groove, further reducing frictional resistance and assisting the friction plate to quickly and smoothly disengage from the mold, without the need for frequent manual intervention to handle unloading abnormalities.

[0020] Example

[0021] refer to Figures 1 to 5This embodiment describes a friction plate stamping die with rapid material ejection, comprising a base 1, a frame 2 fixedly connected to one side of the base 1, a cylinder 3 fixedly connected to the top of the frame 2, a lifting plate 4 fixedly connected to the output end of the cylinder 3, an upper die base 5 fixedly connected to the bottom end of the lifting plate 4, a lower die base 6 fixedly connected to one side of the top of the base 1, a guide groove 7 provided inside the lower die base 6, one side of the guide groove 7 being inclined, and multiple air holes 12 provided inside the guide groove 7, and an air guide cavity 13 provided inside the lower die base 6, the air holes 12 communicating with the air guide cavity 13, and an air pump 14 fixedly connected to one side of the lower die base 6, the air pump 14 being connected to... The air guide chamber 13 is connected. Both sides of the bottom end of the lifting plate 4 are fixedly connected with through rods 11. Both sides of the interior of the lower mold base 6 are provided with through holes 10. One side of the lower mold base 6 is provided with a pusher assembly 8, and there are four pusher assemblies 8. Compared with the traditional single pusher structure, the four pusher assemblies 8 can push the friction plate to move more stably. One side of the pusher assembly 8 is provided with a transmission assembly 9. One side of the through rod 11 slides through the through hole 10 and is movably connected to the transmission assembly 9. After the friction plate is formed, the transmission assembly 9 is no longer under pressure. The pusher assembly 8 resets and pusher block 81 pushes the friction plate to move upward. By eliminating external driving devices such as cylinder 3 and electric push rod, the initial purchase cost of the mold can be greatly reduced, the production and operation cost can be reduced, and the impact force caused by excessive speed can be avoided to prevent mold damage.

[0022] refer to Figure 1 , Figure 4 , Figure 5 The pusher assembly 8 includes a support block 84, which is slidably connected to the lower die base 6. A shock-absorbing spring 82 and a damper 83 are fixedly connected to the top of the support block 84. The shock-absorbing spring 82 is sleeved on the outside of the damper 83. A pusher block 81 is fixedly connected to the common top of the shock-absorbing spring 82 and the damper 83. The pusher block 81 is movably connected inside the guide groove 7. Fixing frames 87 are fixedly connected to both sides of the interior of the lower die base 6. A slider 85 is slidably connected to the inner side of the fixing frame 87. The top of the slider 85 is fixedly connected to the bottom of the support block 84. Next, pulleys 86 are installed on both sides of the slider 85, and the pulleys 86 are slidably connected inside the fixed frame 87. By setting the pusher assembly 8, when the transmission assembly 9 is pressed, the support block 84 compresses the damping spring 82 along the inner side of the fixed frame 87, and the pusher block 81 descends synchronously with the support block 84. After the pressure of the transmission assembly 9 is released, the pusher block 81 returns to its original position. Under the action of the damping spring 82 and the damper 83, the impact force of the pusher block 81 on the mold friction plate is reduced, protecting the friction plate. When the support block 84 moves up and down, the pulleys 86 on both sides of the slider 85 roll in the guide rail of the fixed frame 87, reducing frictional resistance.

[0023] refer to Figure 4 The transmission assembly 9 includes a transmission plate 91, which is slidably connected inside the lower mold base 6. One side of the through rod 11 is movably connected to one side of the transmission plate 91. A return spring 94 is fixedly connected between the transmission plate 91 and the lower mold base 6. Transmission blocks 92 are fixedly connected to both sides of the transmission plate 91. A transmission rod 93 is fixedly connected to the top of the transmission block 92. One side of the transmission rod 93 moves against one side of the slider 85. By setting the transmission assembly 9, the through rod 11 moves downward to push the transmission plate 91 to compress the return spring 94. The transmission plate 91 drives the two transmission blocks 92 to move downward synchronously. The transmission blocks 92 drive the transmission rod 93 to move, so that the transmission rod 93 leaves the slider 85. At this time, the pusher block 81 moves downward. After the through rod 11 moves upward, the return spring 94 pushes the transmission plate 91 to reset. The pusher assembly 8 springs back and pushes out the friction plate.

[0024] refer to Figure 4 The transmission plate 91 is fixedly connected to a guide rod 95 on one side of the return spring 94. One side of the guide rod 95 slides through the lower mold base 6. By setting the guide rod 95, the transmission plate 91 moves more stably under the action of the return spring 94, avoiding deviation.

[0025] Operating principle and advantages: Cylinder 3 pushes the lifting plate 4 downward, causing the upper mold base 5 to gradually approach the lower mold base 6. During this process, the through rods 11 on both sides of the bottom end of the lifting plate 4 move downward, pass through the through holes 10 on both sides inside the lower mold base 6, and contact the transmission plate 91 in the transmission assembly 9, pushing the transmission plate 91 to compress the return spring 94. The transmission blocks 92 on both sides of the transmission plate 91 move downward synchronously, and the transmission rod 93 at the top of the transmission block 92 leaves the slider 85, so that the slider 85 loses the constraint of the transmission rod 93 in the fixed frame 87. Under the action of the pusher assembly 8, the support block 84 slides downward along the inner side of the fixed frame 87, compressing the shock absorber spring 82 and the damper 83, causing the pusher block 81 to descend and enter the guide groove 7 of the lower mold base 6, reserving space for the upcoming friction plate stamping. The upper mold base 5 and the lower mold base 6 are completely closed, applying pressure to the sheet material placed on the lower mold base 6. Through the action of the mold cavity, the sheet material is stamped into a friction plate. In the entire stamping process... In the process, the pusher block 81 remains within the lower die base 6 to ensure that the normal stamping operation is not affected. After the stamping is completed, the cylinder 3 drives the lifting plate 4 to move upward, the upper die base 5 separates from the lower die base 6, and the through rod 11 moves upward accordingly, relieving the pressure on the transmission plate 91. At this time, the transmission plate 91 is reset under the action of the return spring 94, and the transmission rod 93 re-contacts the slider 85, pushing the slider 85 to slide inside the fixed frame 87. The slider 85 drives the support block 84 to move upward. The shock-absorbing spring 82 and damper 83 at the top of the support block 84 push the pusher block 81 to push the formed friction plate upward from the guide groove 7. At the same time, the air pump 14 on one side of the lower die base 6 starts and delivers gas to the air guide cavity 13. The gas is sprayed into the guide groove 7 through multiple air holes 12 connected to the air guide cavity 13. Since one side of the guide groove 7 is inclined, under the dual action of the pusher block 81 pushing out and the high-pressure gas, the friction plate quickly and smoothly leaves the mold along the guide groove 7, completing the unloading process.
