[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Refer to Figure 1 and Figure 2 , an embodiment provided by the present utility model: A die with a punch pushed by the inclined surface of a ejector rod, including a bottom plate 1, the upper surface of the bottom plate 1 is fixedly connected with a fixed plate 2, the upper surface of the fixed plate 2 is fixedly connected with a fixed die 3, the upper surface of the bottom plate 1 is fixedly connected with a support plate 5, the lower surface of the support plate 5 is fixedly connected with a telescopic rod 6, the output end of the telescopic rod 6 is fixedly connected with a moving die 7, the lower surface of the moving die 7 is fixedly connected with an upper inclined block 8, and a processing assembly is arranged inside the fixed die 3. The processing assembly is used for processing operations such as drilling parts. The processing assembly includes a lower inclined block 4, the lower inclined block 4 is slidably connected inside the fixed die 3, a chute 11 is opened inside the fixed die 3, the lower inclined block 4 is slidably connected inside the chute 11, and a punch needle 12 is fixedly connected to the outer wall of the lower inclined block 4;
[0025] Specifically, start the telescopic rod 6 to drive the moving die 7 to move downward. During the downward movement of the moving die 7, the two upper inclined blocks 8 are driven to move downward. After the upper inclined blocks 8 move downward and contact the lower inclined blocks 4, the lower inclined blocks 4 are squeezed and pushed to slide inside the fixed die 3. The two lower inclined blocks 4 slide towards the middle position of the fixed die 3 at the same time. During the sliding, the two groups of punch needles 12 are also driven to slide and approach each other, so that the punch needles 12 perform processing operations on the workpiece, realizing the effect of automatic processing of the inclined surface of the ejector rod.
[0026] Refer toFigure 1 , Figure 2 and Figure 3 , a baffle 9 is fixedly connected to the outer wall of the fixed die 3. A first spring 10 is arranged inside the fixed die 3. One end of the first spring 10 is fixedly connected to the outer wall of the lower inclined block 4, and the other end of the first spring 10 is fixedly connected to the outer wall of the baffle 9. A sliding rod 13 is fixedly connected to the outer wall of the moving die 7. A fixed column 14 is fixedly connected to the outer wall of the baffle 9. The fixed column 14 is slidably connected inside the sliding rod 13. A limiting groove 15 is formed inside the sliding rod 13. The fixed column 14 is slidably connected inside the limiting groove 15;
[0027] Specifically, after the lower inclined block 4 slides to the middle position of the fixed die 3, when the moving die 7 drives the upper inclined block 8 to rise, the lower inclined block 4 will slide to both sides due to the elastic reset effect of the first springs 10 fixed to the outer walls of the two baffles 9, so that the two lower inclined blocks 4 are automatically reset. During the downward sliding process of the moving die 7, the four groups of sliding rods 13 are also driven to slide. Limited by the fixed column 14, the effect of auxiliary processing limit is achieved, preventing the moving die 7 from shifting in position.
[0028] Referring to Figure 1 and Figure 4 , a sliding column 16 is fixedly connected to the lower surface of the moving die 7. A positioning groove 17 is formed inside the fixed die 3. A sliding shaft 18 is slidably connected inside the fixed die 3. A limiting plate 19 is fixedly connected to the outer wall of the sliding shaft 18. The limiting plate 19 is slidably connected inside the fixed die 3. A clamping plate 20 is fixedly connected to the outer wall of the limiting plate 19. A second spring 21 is sleeved on the outer wall of the sliding shaft 18. One end of the second spring 21 is fixedly connected inside the fixed die 3, and the other end of the second spring 21 is fixedly connected to the outer wall of the limiting plate 19. A placing groove 22 is formed inside the fixed die 3;
[0029] Specifically, during the downward movement of the moving die 7, the four sliding columns 16 are also driven to move downward and are inserted into the positioning grooves 17 inside the fixed die 3 to form a positioning effect. The workpiece needs to be clamped and fixed. Before processing, the workpiece needs to be placed in the placing groove 22 inside the fixed die 3. When the workpiece is placed, it will squeeze the clamping plates 20 on both sides, driving the sliding shaft 18 and the limiting plate 19 to slide through the squeezing of the clamping plates 20. When the workpiece is clamped by the two clamping plates 20, the second spring 21 will reset and resist the clamping plates 20, thus achieving the clamping effect.
[0030] Working principle: When using a mold that uses the inclined surface of the ejector rod to push the punch, first place the workpiece in the placement groove 22 inside the fixed mold 3, and clamp the workpiece with two clamping plates 20. Due to the elastic reset effect of the second spring 21, the second spring 21 abuts against the inside of the limit plate 19 and the fixed mold 3, thereby pressing the clamping plates 20 against the outer wall of the workpiece to clamp the workpiece. At this time, start the two telescopic rods 6 to drive the moving mold 7 to move downward. During the downward movement of the moving mold 7, the upper inclined blocks 8 on both sides are driven to move downward. When the upper inclined blocks 8 move downward to the position of the lower inclined blocks 4, the upper inclined blocks 8 squeeze the lower inclined blocks 4, causing the lower inclined blocks 4 to slide toward the middle position of the fixed mold 3. At the same time as the lower inclined blocks 4 slide, the first spring 10 is also stretched. During the process of the two lower inclined blocks 4 sliding toward the middle, they also drive the two groups of punch needles 12 to slide toward the middle, thereby processing the workpiece. During the downward movement of the moving mold 7, the four groups of sliding rods 13 are also driven to move downward and slide on the outer wall of the fixed column 14. The moving mold 7 also drives the four sliding columns 16 to move downward and slide into the positioning grooves 17, thereby playing a role in positioning and limiting to prevent the moving mold 7 from shifting in position. When the processing is completed, start the telescopic rods 6 to drive the moving mold 7 to move upward. When the moving mold 7 moves upward, it drives the two upper inclined blocks 8 to move upward. After the upper inclined blocks 8 move upward, the two lower inclined blocks 4 automatically reset due to the reset effect of the first spring 10, thus achieving the effect of automatically using the inclined surface of the ejector rod to push the punch for processing.
[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
