Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a stamping die with a replaceable stamping die head. Background Technology

[0002] Stamping is a process that uses a press to apply pressure to sheet metal using a die, thereby obtaining parts of the desired shape. Stamping dies are the supporting molds used in stamping processes.

[0003] During stamping, the press pushes the die head at the bottom of the upper die plate, causing the die head to press downwards against the material plate. This, combined with the stamping holes in the lower die plate, produces a part of the desired shape. However, after too many stamping cycles, the die head will experience wear or deformation, resulting in dimensional deviations in the stamped parts. Consequently, the die head needs to be replaced. However, traditional die heads are usually fixed to the upper die with multiple bolts, making it inconvenient to disassemble and assemble the die head. Therefore, we propose a stamping die with a replaceable die head. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a stamping die with a replaceable stamping die head, so as to solve the technical problem that the current die head is generally fixed to the upper die by multiple bolts, which makes it inconvenient to disassemble and assemble the die head.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A stamping die with a replaceable stamping die head includes a stamping die assembly, wherein an upper die is provided on the stamping die assembly, characterized in that: an assembly base is detachably mounted on the upper die;

[0008] The assembly base has an integrally formed mold head at the end away from the upper mold. Both the upper mold and the assembly base are equipped with pins, and the mold head is detachably mounted on the upper mold via the assembly base and the pins.

[0009] As an improved technical solution, the bottom of the upper mold is provided with symmetrically arranged assembly slots;

[0010] The top of the mounting base has an integrally formed mounting block that corresponds to the mounting groove, and the mounting block is adapted to the mounting groove.

[0011] As an improved technical solution, a first limiting groove is provided on one side of the inner cavity of the assembly groove, and a second limiting groove is provided on the other side of the inner cavity of the assembly groove.

[0012] One side of the assembly base has an integrally formed first limiting plate corresponding to the first limiting groove, and the first limiting plate is adapted to the first limiting groove. The other side of the assembly base has an integrally formed second limiting plate corresponding to the second limiting groove, and the second limiting plate is adapted to the second limiting groove. The assembly base is installed on the bottom of the upper mold through the assembly groove and the assembly block, the first limiting groove and the first limiting plate, and the second limiting groove and the second limiting plate.

[0013] As an improved technical solution, the first limiting plate and the second limiting plate are arranged asymmetrically.

[0014] As an improved technical solution, the upper mold has symmetrical snap-fit ​​grooves on both sides, and the mounting base has integrally formed snap-fit ​​blocks on both sides that correspond to the snap-fit ​​grooves. The snap-fit ​​blocks are adapted to the snap-fit ​​grooves, and the mounting base is installed on the side of the upper mold through the snap-fit ​​grooves and the snap-fit ​​blocks.

[0015] As an improved technical solution, the snap-fit ​​block is an inverted U-shaped structure with an integrally formed horizontal and vertical part. One end of the horizontal part is installed on both sides of the mounting base, and the other end of the horizontal part is snap-fitted into the snap-fit ​​groove.

[0016] As an improved technical solution, the upper mold has first insertion holes on both sides that are adapted to the pin, and the first insertion holes are adapted to the pin.

[0017] The vertical section has a second insertion hole that matches the pin. When in the installation state, the first insertion hole and the second insertion hole are coaxial. The mounting base is installed on the upper mold through the first insertion hole, the second insertion hole and the pin.

[0018] After adopting the above technical solution, the beneficial effects of this utility model are:

[0019] This invention involves assembling the mold head onto the upper mold, with the assembly base mounted on the bottom of the upper mold. An assembly block is installed in the assembly groove, a first limiting plate is installed in the first limiting groove, a second limiting plate is installed in the second limiting groove, and a snap-fit ​​block is installed in the snap-fit ​​groove. Simultaneously, the first insertion hole and the second insertion hole are coaxial. Then, a pin is used to fix the assembly base onto the upper mold. The pin enters the first insertion hole through the second insertion hole, thus fixing the assembly base onto the upper mold, completing the installation of the mold head. The operation is simple and quick. If the mold head needs to be disassembled, the above steps are reversed, facilitating the assembly and disassembly of the mold head. Attached Figure Description
