[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model utilizes the design of a hydraulic cylinder, which drives the punch to move. In conjunction with the action of the lower die, parts can be stamped. During the stamping process, the elastic action of the first and second springs can buffer the instantaneous impact force, reducing damage to the die frame and extending its service life.

[0014] 2. This utility model utilizes the design of an inclined seat. When the pressure rod moves down, it can compress the inclined seat, which will push the inclined block and drive the connecting rod to move horizontally. The connecting rod will compress the third spring, and under the elastic action of the third spring, the impact force can be further buffered, improving the buffering effect. After the stamping is completed, the separation of the pressure rod and the inclined seat can realize the vertical movement of the connecting plate, which is convenient for ejecting the formed parts and for taking out the formed workpiece.

The slider 84 is slidably connected to the connecting seat 81. A first spring 85 is provided inside the connecting seat 81. One end of the first spring 85 is fixedly connected to the slider 84, and the other end of the first spring 85 is fixedly connected to the guide rod 86. By designing the first spring 85, the first spring 85... The force can be applied to the slider 84. The guide rod 86 is slidably sleeved inside the connecting seat 81. The fixed seat 87 is slidably sleeved outside the guide rod 86. The fixed seat 87 is fixedly connected to the base plate 1. The fixed seat 87 is provided with a second spring 88.

By designing the second spring 88, the force of the second spring 88 can be applied to the guide rod 86. By designing the buffer mechanism 8, the impact force of the stamping can be buffered.

[0023] Please see Figure 1 , Figure 4 The ejector mechanism 9 includes a pressure rod 91. The lower end of the pressure plate 7 is fixedly connected to the pressure rod 91. The lower mold 3 has two symmetrically distributed inclined seats 92 that are slidably sleeved inside. The inclined seats 92 are slidably connected to the worktable 2. The outer side of the inclined seats 92 is fixedly connected to the connecting rod 93. The lower mold 3 has a third spring 94 inside. One end of the third spring 94 is fixedly connected to the connecting rod 93, and the other end of the third spring 94 is fixedly connected to the lower mold 3. By designing the third spring 94, the force of the third spring 94 can be applied to the connecting rod 93. The upper end of the connecting rod 93 contacts an inclined block 95.

By designing the ejector mechanism 9, it is convenient to remove the molded workpiece.

[0024] The specific implementation process of this utility model is as follows: When in use, first place the workpiece on the lower mold 3, then start the hydraulic cylinder 6. The output end of the hydraulic cylinder 6 drives the pressure plate 7 to move down, and the pressure plate 7 will drive the punch 10 to move down to stamp and form the workpiece.

[0025] During the downward movement of the pressure plate 7, the pressure plate 7 will drive the connecting seat 81 to move downward, and the connecting seat 81 will drive the guide rod 86 to move downward. The guide rod 86 will slide along the fixed seat 87 and squeeze the second spring 88. When the second spring 88 is compressed to a certain position, the guide rod 86 will squeeze the first spring 85 at the same time. Under the elastic action of the first spring 85 and the second spring 88, the instantaneous impact force can be buffered, which can reduce the damage of the impact force to the mold frame and improve the service life of the mold frame. When the first spring 85 is squeezed, the first spring 85 will push the slider 84 to move upward, and the slider 84 will squeeze the sponge pad 83. At this time, the lubricating oil inside the sponge pad 83 will be squeezed out and the lubricating oil will flow along the guide rod 86, which can achieve the purpose of lubricating the connecting seat 81, the guide rod 86 and the fixed seat 87, and reducing the friction during buffer sliding.

[0026] During the downward movement of the pressure plate 7, the pressure plate 7 will also drive the pressure rod 91 to move. The pressure rod 91 will slide along the inclined surface of the inclined seat 92. The inclined seat 92 will be squeezed and pushed to slide into the lower die 3. The inclined seat 92 will drive the connecting rod 93 to move horizontally and squeeze the third spring 94. Under the elastic action of the third spring 94, the impact force can be further buffered, and the buffering effect can be improved. When the connecting rod 93 moves inward, the inclined block 95 and the connecting plate 96 will move downward due to gravity. Then, the punch 10 can be used to perform stamping in cooperation with the lower die 3. After the stamping is completed, the punch 10 will be reset under the action of the pressure plate 7. At the same time, the pressure plate 7 will drive the pressure rod 91 to separate from the inclined seat 92. At this time, under the elastic action of the third spring 94, the connecting rod 93 will be given an outward counter-push force. At this time, the connecting rod 93 can slide outward along the inclined surface of the inclined block 95. The inclined block 95 will be squeezed and pushed upward. The inclined block 95 can drive the connecting plate 96 to move upward, which is convenient for ejecting the molded parts and for taking out the molded workpiece.
