Technical Field

[0001] The utility model relates to the technical field of cutting dies, in particular to a closed bevel cutting die with a replaceable die core. Background Art

[0002] Closed cutting molds are molds used to achieve precise cutting operations during the processing process. This type of mold is mainly used for processing metal sheets, plastic sheets or other plastic materials. Its characteristic is that the processing process is completed inside a closed mold.

[0003] Chinese patent publication number CN219169361U, publication date 20230613, discloses a cutting die for cutting long conditions, wherein the long conditions are provided with slots along their length direction. The cutting die comprises: a lower die, comprising a movable module and a fixed module for placing the long conditions; the movable module is movably arranged on the fixed module and can be inserted into the slot; an upper die, which is liftably arranged above the lower die, comprises a push block and a cutter for cutting the long conditions; when the upper die moves downward, the push block can abut against the movable module and drive the movable module to be inserted into the slot.

[0004] Existing closed cutting dies such as the above mostly use a liftable cutter head in conjunction with a mold core to achieve product cutting. In the specific implementation process, the cutting grooves in the existing cutter heads are mostly straight. If the cutting surface of the product has an inclined surface, it is often necessary to replace the cutter head for a second cutting, which greatly affects the cutting efficiency of the product. Therefore, it is urgent to propose a corresponding closed beveling cutting die with a replaceable mold core to solve the above problems. Utility Model Content

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A closed beveling mold with a replaceable mold core comprises a fixed seat and a cutting seat that are fixedly connected. A cutter head is slidably connected to the inner wall of the cutting seat. A spring is fixedly connected between the bottom of the cutter head and the top of the fixed seat. The cutter head and the inner wall of the cutting seat are respectively detachably connected to the mold core and the guide seat. A cutting groove is provided on the rear end face of the cutter head, and the cutting groove consists of a right-angle section and an inclined section.

[0008] Preferably, the inner surface wall of the cutting seat is fixedly connected with a protruding rod, and the outer surface wall of the protruding rod is slidably connected to the inner surface wall of the cutter head through a vertical groove.

[0009] Preferably, the springs are provided in multiple groups, and the multiple groups of springs are horizontally linearly distributed.

[0010] Preferably, the outer wall of the cutting seat is fixedly connected to a limiting plate, and the inner wall of the limiting plate abuts against the outer wall of the cutter head.

[0011] Preferably, the outer wall of the core component is fixedly connected with a side piece, and the side piece is fixedly connected to the cutter head via a locking rod.

[0012] Preferably, a connecting piece is fixedly connected to the outer wall of the cutting seat, and the connecting piece is fixedly connected to the cutting seat via a fastening rod.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0014] 1. In this application, the product passes through the guide seat and the core piece in turn, the cutter head is pressed to move vertically, the spring is compressed, and the cutter head cooperates with the core piece to complete the cutting of the product. Since the cutting groove is composed of continuous right-angle segments and inclined segments, the cross-section of the product after a single cut will have an inclined surface, and no secondary processing is required, thereby improving the product cutting efficiency. At the same time, the locking rod and the fastening rod can be rotated in turn to separate the cutter head and the cutting seat, so that the core piece and the guide seat can be separated, so that the core pieces and the guide seat with different apertures can be quickly disassembled and assembled, thereby improving the convenience of using the closed bevel cutting mold.

[0015] 2. In the present application, in the process of pushing the cutter head to move vertically, the vertical groove inside the cutter head will slide and cooperate with the convex rod on the inner wall of the cutting seat, thereby further ensuring the stability of the vertical movement of the cutter head and limiting the extreme travel positions on both sides of the vertical direction of the cutter head, thereby ensuring the stability of the use of the closed bevel cutting mold.

[0025] The product passes through the guide seat 12 and the core piece 8 in turn, pressing the cutter head 4 to move it vertically, the spring 11 is compressed, and the cutter head 4 cooperates with the core piece 8 to complete the cutting of the product. Since the cutting groove 5 is composed of a continuous right-angle segment 501 and an inclined segment 502, the cross-section of the product after a single cut will have a bevel, and no secondary processing is required, thereby improving the product cutting efficiency. At the same time, the locking rod 10 and the fastening rod 14 can be rotated in turn to separate the cutter head 4 and the cutting seat 2, so that the core piece 8 can be separated from the guide seat 12, so that the core pieces 8 and the guide seat 12 with different apertures can be quickly disassembled and assembled, thereby improving the convenience of using the closed bevel mold.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, the inner wall of the cutting seat 2 is fixedly connected with a protruding rod 7, and the outer wall of the protruding rod 7 is slidably connected to the inner wall of the cutter head 4 through a vertical groove 6. In the process of pushing the cutter head 4 to move vertically, the vertical groove 6 inside the cutter head 4 will slide and cooperate with the protruding rod 7 on the inner wall of the cutting seat 2, thereby further ensuring the stability of the vertical movement of the cutter head 4 and limiting the extreme travel positions on both sides of the vertical direction of the cutter head 4, thereby ensuring the stability of the use of the closed beveling mold.

[0027] Specifically, such as Figure 2 and Figure 3As shown, multiple groups of springs 11 are provided, and the multiple groups of springs 11 are distributed horizontally and linearly to ensure the stability of the vertical reset of the cutter head 4. The outer wall of the cutting seat 2 is fixedly connected to the limit plate 3, and the inner wall of the limit plate 3 abuts against the outer wall of the cutter head 4 to limit the horizontal deviation of the cutter head 4. The outer wall of the core piece 8 is fixedly connected to the side piece 9, and the side piece 9 is fixedly connected to the cutter head 4 through the locking rod 10. The outer wall of the cutting seat 2 is fixedly connected to the connecting piece 13, and the connecting piece 13 is fixedly connected to the cutting seat 2 through the fastening rod 14.

[0028] Working principle: the product passes through the guide seat 12 and the core piece 8 in turn, pressing the cutter head 4 to move vertically, the spring 11 is compressed, and the cutter head 4 cooperates with the core piece 8 to complete the cutting of the product. Since the cutting groove 5 is composed of a continuous right-angle segment 501 and an inclined segment 502, the cross-section of the product after a single cutting will have an inclined surface, and no secondary processing is required, thereby improving the product cutting efficiency. At the same time, the locking rod 10 and the fastening rod 14 can be rotated in turn to separate the cutter head 4 and the cutting seat 2, so that the core piece 8 and the guide seat 12 can be separated, so that the core pieces 8 and the guide seat 12 of different apertures can be quickly disassembled and assembled, thereby improving the convenience of using the closed bevel cutting mold. In the process of pushing the cutter head 4 to move vertically, the vertical groove 6 inside the cutter head 4 will slide with the convex rod 7 on the inner wall of the cutting seat 2, thereby further ensuring the stability of the vertical movement of the cutter head 4, and limiting the extreme travel positions on both sides of the vertical direction of the cutter head 4, thereby ensuring the stability of the use of the closed bevel cutting mold.
