[0003] China Patent Authorization Announcement No.: CN221209570U provides "A mold manufacturing punching device". This solution designs a limit component to limit and fix the mold when punching the mold, thereby improving the accuracy of the mold punching. At the same time, there is no need to disassemble and assemble the mold, which can improve the punching efficiency of the mold to a certain extent.

When performing continuous equidistant punching operations, the staff needs to constantly move the mold and reposition the mold, which is cumbersome and reduces the work efficiency of continuous equidistant punching operations.

[0005] Therefore, in order to solve the above problems, a punching device for mold processing is proposed. Utility Model Content

[0031] Example:

[0032] See also Figure 1 - Figure 5 , a punching device for mold processing, including a side plate 1 and a bottom plate 2, the bottom plate 2 is fixedly connected to one side of the side plate 1, one side of the side plate 1 is fixedly connected to two symmetrically arranged fixing frames 3, one side of one fixing frame 3 is fixedly connected to a motor 4, a screw rod 5 is rotatably connected between the two fixing frames 3, one end of the screw rod 5 passes through one of the fixing frames 3 and is transmission connected to the output end of the motor 4, the external thread of the screw rod 5 is connected to several sliding plates 6 with the same spacing, the top surface of the inner wall of one of the fixing frames 3 is rotatably connected to a limiting link 7, the top and center positions of several sliding plates 6 are rotatably connected with an extension link 8, one of the extension link 8 is rotatably connected to the limiting link 7, the two adjacent extension links 8 are rotatably connected, and one side of the several sliding plates 6 is fixedly connected to two symmetrically arranged clamping plates 9.

[0033] In this solution, the length of the limiting link 7 is half of the stretching link 8, and the length of the stretching link 8 farthest from the limiting link 7 is the same as that of the limiting link 7. The clamping plate 9 is used to clamp the polishing workpiece, and the specific shape of the clamping plate 9 is adapted to the shape of the polishing workpiece; after the motor 4 is started, the screw 5 starts to rotate, thereby causing the sliding plate 6 to move thereon, and the limiting link 7 is driven to rotate by the sliding plate 6 connected to it, and cooperates with the rotation cooperation between the various stretching links 8, so that the spacing between the multiple sliding plates 6 increases continuously during the movement and always remains the same, thereby making the spacing between the multiple polishing works the same, and realizing the equidistant punching operation of the mold;

[0034] By setting up a motor 4 to drive the screw rod 5 to rotate, multiple sliding plates 6 are moved on the screw rod 5, and the limiting link 7 and multiple extension links 8 are used to limit the multiple sliding plates 6, so that the spacing between the multiple sliding plates 6 continues to increase and always remains the same during the movement, so that the spacing between multiple polishing parts is the same, and the mold is punched at equal distances, which effectively solves the problem that traditional punching devices require multiple positioning to perform equal-distance punching.

[0035] See also Figure 1 - Figure 3 A scale 10 is provided on one side of the side panel 1, and an indicator bar 11 is fixedly connected to the top of the sliding plate 6. The center line of the indicator bar 11 and the center line of the sliding plate 6 are located in the same vertical plane.

[0036] In this solution, the scale 10 is located between the two fixing frames 3, and the top of the indicator bar 11 is vertical and points directly upward. During the movement of the sliding plate 6, the indicator bar 11 is the position of the center line of the sliding plate 6. Since the clamping plates 9 are symmetrically installed on one side of the sliding plate 6, the staff can identify the position of the indicator bar 11 as the middle position of the two clamping plates 9, that is, the position of the polishing piece;

[0037] By observing the position of the indicator bar 11 on the scale 10, the staff can calculate the specific distance between the two grinding parts, which effectively solves the problem that the traditional punching device needs the staff to constantly measure the distance of the punching position when performing continuous equidistant punching, thereby improving the convenience of the device.

[0038] See also Figure 1 and Figure 2 Two symmetrically arranged guide rods 12 are fixedly connected between the two fixing frames 3 , and both guide rods 12 are slidably connected to the sliding plate 6 .

[0039] In this solution, the guide rod 12 is used to limit and guide the movement of the sliding plate 6 to ensure its smooth movement.

[0040] See also Figure 1 、 Figure 2 and Figure 4 Two fixing holes 91 are formed on one side of the two clamping plates 9 , and the inner threads of the two corresponding fixing holes 91 are connected with No. 1 bolts 92 .

[0041] In this solution, the No. 1 bolt 92 cooperates with the fixing hole 91 to clamp and fix the two clamping plates 9, and the two clamping plates 9 have a certain elasticity.

[0042] See also Figure 1 and Figure 5 Two slide grooves 13 are provided on the top surface of the bottom plate 2 , and two symmetrically arranged bases 14 are slidably connected inside the two slide grooves 13 .

[0043] Specifically, a plurality of evenly distributed positioning holes 15 are opened inside the slide groove 13 , and two No. 2 bolts 16 are threadedly connected through the bottom surface of the base 14 , and the No. 2 bolts 16 are threadedly connected to the positioning holes 15 .

[0044] Specifically, a plurality of evenly distributed spring rods 17 are fixedly connected to the top of the base 14 , and a pressure plate 18 is fixedly connected to the top of the plurality of spring rods 17 .

[0045] In this solution, by connecting the No. 2 bolts 16 with the various positioning holes 15, the positions of the two bases 14 can be adapted to molds of different lengths, and the spring rod 17 provides elastic force so that the pressure plate 18 can press and fix the mold, so that the device can perform equidistant punching operations on molds of different lengths.

[0046] Working principle: First, the staff turns on the motor 4 to drive the screw 5 to rotate, so that the sliding plate 6 moves on the screw 5, and cooperates with the limit link 7 and the extension link 8 to make the spacing between the multiple sliding plates 6 continue to increase during the movement and always remain the same. At the same time, the staff observes the position of the indicator bar 11 on the scale 10. After subtracting the position data of the two indicator bars 11, if it is the same as the planned position, the staff can turn off the motor 4 in time to fix the position of the sliding plate 6. Then the staff fixes the polishing parts one by one on the multiple sliding plates 6 through the clamping plate 9, and moves the base 14 according to the overall position of the multiple sliding plates 6, and fixes the mold directly below the multiple sliding plates 6 as a whole through the cooperation between the No. 2 bolt 16 and the positioning hole 15. Then the staff pulls the pressure plate 18 upwards, and the elastic force generated by the spring rod 17 makes the pressure plate 18 clamp the mold. Finally, the staff turns on the polishing part and starts punching holes in the mold at equal distances.

[0047] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
