Description

Technical Field

[0001] This utility model relates to the field of stamping die equipment technology, specifically a stamping die with replaceable stamping die core. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process metal or non-metal materials into parts. During stamping, stamping dies can apply pressure to the material using dies mounted on a press, causing it to separate or undergo plastic deformation, thereby obtaining the desired new parts and increasing the processing speed of parts.

[0003] For example, the utility model patent disclosed in publication number CN218891099U discloses a component stamping die that facilitates core replacement. It includes a base, an auxiliary block fixedly connected to the top of the base, and a quick replacement device on the auxiliary block. The core block is limited by setting an installation groove and a sliding groove, and the pressure block is limited by setting a threaded block and a threaded cylinder. After the core block and the pressure block are installed, the pressure block and the inner wall of the core block are already aligned in the vertical direction, eliminating the need for further adjustment, reducing operation steps and improving work efficiency.

[0004] Although the above-mentioned equipment can replace the stamping die core, its replacement speed and efficiency are insufficient. At the same time, the above-mentioned stamping die is not convenient for quickly and stably ejecting the workpiece excess material, which reduces the efficiency of subsequent workpiece processing. Therefore, there is an urgent need for a stamping die with replaceable stamping die core to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a stamping die with a replaceable stamping die core to solve the problems mentioned in the background art.

[0007] The limiting bracket has two sets, and the two sets of the limiting bracket are threadedly connected to the inner end face of the support guide through the threaded guide shaft;

[0008] A shaping device, wherein the shaping device is fixedly engaged with the inner end face of the support guide by two sets of limiting brackets;

[0009] A stamping device is fixedly mounted on the top of the support guide.

[0010] Preferably, the molding device includes a mold core housing for support, four sets of spring retaining rings are fixedly arranged at equal intervals on the lower end face of the mold core housing, a guide base is fixedly arranged on the lower end face of the four sets of spring retaining rings, and four sets of ejector guide shafts are arranged at equal intervals on the upper end face of the guide base, and limit slots are symmetrically opened on the side end face of the mold core housing.

[0011] Preferably, the stamping device includes a transmission electric cylinder, the output end of which is fixedly provided with a stamping guide seat, and a stamping die is fixedly provided at the center of the lower end face of the stamping guide seat.

[0012] Preferably, the limiting bracket is fixedly engaged with the mold core housing through the limiting slot. The two sets of limiting brackets can limit the inside of the limiting slot under the synchronous drive of the two sets of threaded guide shafts, thereby facilitating the subsequent limiting and disassembly of the mold core housing.

[0013] Preferably, the ejector guide shaft is elastically slidably engaged with the inner end face of the mold core housing via the spring retainer. When the ejector guide shaft is stamped by the stamping die, it can elastically move downward under the limit of the workpiece. After stamping is completed, the spring retainer can eject the workpiece residue by providing elastic force to the ejector guide shaft, which facilitates the continuous processing of a new set of workpieces.

[0014] Preferably, the stamping die is slidably engaged with the inner end face of the mold core housing. The stamping die can stamp and shape the workpiece that is limited inside the mold core housing, which can effectively improve the stability and accuracy of subsequent workpiece processing.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. When the mold core housing is replaced, the servo motor can synchronously drive two sets of threaded guide shafts to rotate through the synchronous pulley, synchronous belt and transmission guide shaft. This allows the two sets of threaded guide shafts to quickly and stably disassemble and lock the mold core housing through the limit locator, effectively improving the convenience of disassembling the mold core housing and the stability of locking. At the same time, after stamping, the spring retainer can drive the ejector guide shaft through the guide base to automatically eject the workpiece residue, effectively improving the efficiency of the equipment for subsequent continuous processing of the workpiece.
