Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a composite blanking mold. Background Technology

[0002] Blanking dies primarily use an upper and lower die to cut thin sheets into workpieces of the desired shape. Existing blanking dies typically use one die per workpiece. Even when the only difference between two workpieces is the presence or absence of holes, the current practice of using one die per workpiece leads to resource waste and increased production costs. Therefore, it is essential to develop a composite blanking die capable of producing both perforated and non-perforated workpieces. Utility Model Content

The second upper mounting block 34 is detachably connected to the mounting plate 16 by being inserted into the limit groove through the upper limit block 341. The second punching rod 32 is attached to the second upper mounting block 34.

[0040] Please see Figure 2 and Figure 3 The punching assembly 30 also includes a guide block 35, which is fixed to the upper module 18 by screwing. The guide block 35 is provided with a guide hole, and the lower end of the second punching rod 32 passes through the guide hole and extends out of the upper module 18.

[0041] Please see Figure 2 and Figure 4 The lower module 22 is provided with a recess and a mounting slot, each corresponding one-to-one with a punching seat. The recess is divided into a first recess and a second recess, with the first punching seat 36 embedded in the first recess and the second punching seat 37 embedded in the second recess. The mounting slot is divided into a first mounting slot and a second mounting slot, with the first mounting slot communicating with the first recess and the second mounting slot communicating with the second recess.

[0042] Please see Figure 2 and Figure 4 The punching assembly 30 further includes a lower limiting block, which corresponds one-to-one with the punching seat. The lower limiting block is divided into a first lower limiting block 38 and a second lower limiting block 39.

The first punching seat 36 is provided with a first limiting platform, and the first lower limiting block 38 abuts against the first limiting platform to limit the position of the first punching seat 36.

[0043] Please see Figure 2and Figure 4 The second lower limit block 39 is detachably connected to the lower module 22 via a screw connection and is disposed in the second mounting groove. The second punch seat 37 is provided with a second limiting platform, and the second lower limit block 39 abuts against the second limiting platform to limit the position of the second punch seat 37. In this way, the operator can dynamically assemble and disassemble the first punch rod 31, the second punch rod 32, the first punch seat 36, and the second punch seat 37 according to actual needs, thus eliminating the need for one mold per workpiece, reducing resource waste, and lowering production costs.

[0044] The working process of the composite blanking mold 100 described in this embodiment is as follows: When making a workpiece, the substrate is placed between the upper mold 10 and the lower mold 20. The stamping equipment drives the upper mold 10 to move downward, and the upper pressure plate 17 and the lower pressure plate 24 cooperate to press the substrate. Then, the stamping equipment drives the drive plate 19 to move downward, and the movable plate 13 carries the upper module 18 downward to press with the lower module 22 to stamp out the workpiece. When preparing a workpiece without holes, it is only necessary to remove the punching rod and the corresponding punching seat installed on the upper mold 10, without the need to prepare an additional set of molds, reducing resource waste and lowering production costs.

[0045] The beneficial effects of this utility model are as follows: the punching rod is detachably mounted on the upper die 10, and the punching seat is detachably mounted on the lower die 20. In this way, the punching rod and the punching seat can be dynamically adjusted according to actual needs, so that one die can produce multiple workpieces, reduce resource waste, and lower production costs.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
