[0004] The utility model discloses a quick die changing device, which is convenient to use the push-pull drawer to replace the ejector, can smoothly move the drawer, does not need an additional power source to push, has a simple overall structure and is convenient to maintain in the later period.
[0005] To achieve the above object, the utility model provides the following technical scheme: a quick die changing device, comprising a front top plate, the front top plate is provided with a push-pull mechanism, and the push-pull mechanism comprises:
[0006] Drawer, the front top plate outside is provided with a drawer, and the drawer can be pulled to drive the front top plate to move;
[0007] Threaded hole structure, the threaded hole structure is used for connecting the front top plate and the drawer by cooperating with the connecting bolt;
[0008] Ejector hole structure, the ejector hole structure is used for connecting the ejector between the front top plate and the drawer.
[0009] Preferably, the end of the front top plate is provided with a lifting ring fixing hole, the end of the drawer is provided with a lifting ring fixing threaded hole, and the lifting ring fixing threaded hole is used for connecting the sliding block.
[0010] Preferably, the threaded hole structure comprises a plurality of first threaded holes arranged on the side edge of the front top plate and a plurality of second threaded holes arranged on the side edge of the drawer, and the connecting bolt is threadedly connected between the second threaded hole and the first threaded hole.
[0011] Preferably, the ejector pin hole structure includes a first ejector pin hole formed on the outer surface of the front top plate and a second ejector pin hole formed on the outer surface of the drawer, and the second ejector pin hole and the first ejector pin hole are used to connect ejector pins.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] The front top plate is connected to the drawer by using a threaded hole structure with connecting bolts. Then, a pin is connected using a pin hole structure, allowing the drawer to be pulled out. Usually, the slider needs to be fixed to the side plate or bottom of the drawer to ensure that the drawer can slide smoothly. Then, the pin is replaced. Due to its simple structure, maintenance is relatively easy. Generally, it only requires regular cleaning and inspection of the slider for wear or damage. Compared with other types of drawer slides, slider drawers have better load-bearing capacity and durability than ball bearing slides, and are also cheaper. Compared with hydraulic or pneumatic drawer slides, slider drawers are easier to install and maintain, and do not require additional hydraulic or pneumatic systems to support their operation. This design allows for quick replacement of pins of different lengths to accommodate injection-molded magnets on shaft heads of shafts of different lengths. Attached Figure Description
