Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a combination structure of a punch and a fixing plate. Background Technology

[0002] There are two existing punch and fixing plate combination structures: a stepped punch fixing plate and a ball lock punch fixing plate. For the stepped punch fixing plate, the steps to disassemble the punch are: remove the upper die from the press and turn it over; then remove and lift out the ejector; remove the screws and pins on the stepped fixing plate; and finally knock out the punch. For the ball lock punch fixing plate, the steps are: remove the upper die from the press and turn it over; then remove and lift out the ejector; finally, use a tool to push the ball lock downwards and pull out the punch. The steps to install the punch for both punch and fixing plate combination structures are the reverse of the disassembly steps.

[0003] It is evident that, regardless of whether it is a stepped punch fixing plate structure or a ball lock punch fixing plate structure, the steps for disassembling the punch are very cumbersome. It requires unmolding, turning over, and removing the ejector before the punch can be disassembled. This is time-consuming, labor-intensive, and inefficient. Moreover, it can only be operated on the production line. When the mold is being debugged on the press or on the production line, it is not possible to operate in situations where the punch is chipped or damaged and needs to be quickly replaced.

When removing the punch 1, there is no need to perform the operations of mold removal, turning over, and removing the ejector. The punch 1 can be removed in a timely and labor-saving manner with high efficiency. Furthermore, the punch 1 can be removed directly on the production line. In cases where the punch 1 is chipped or damaged and needs to be quickly replaced, the operation can be carried out while the mold is being adjusted on the press or on the production line.

[0025] In some embodiments, the first connecting part 13 is cylindrical and has threads on its outer side, and the second connecting part 22 is circular and has threads on its inner side, and the first connecting part 13 and the second connecting part 22 are threadedly connected.

[0026] In this embodiment, the threaded connection makes the first connecting part 13 and the second connecting part 22 detachable. Moreover, when the punch 1 is working, it is only subjected to force along the direction of the punch 1 and is not subjected to torsional force. Therefore, the threaded connection makes the connection between the first connecting part 13 and the second connecting part 22 stable, so that the punch 1 will not detach from the fixed plate 2 when it is working on the production line.
