Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Example 1

As shown in FIGS. 1-3, the plastic mold for hardware punching machine provided by the utility model comprises a base plate 1, a sliding hole is arranged in the middle of the base plate 1, a square rod 11 is slidably connected in the sliding hole, a pressing die 2 is fixedly connected at the lower end of the square rod 11, a transverse plate 3 is fixedly connected at the upper end of the square rod 11, a supporting spring 4 is fixedly connected between the transverse plate 3 and the base plate 1, a mounting rod 5 is fixedly connected at the upper side of the transverse plate 3, the mounting rod 5 is used for being fixedly connected to a pressing machine in the prior art, two mounting columns 6 are respectively and fixedly connected at two ends of the bottom of the base plate 1, an elastic plate 7 is fixedly connected at the outer side of each mounting column 6, the elastic plate 7 is a rubber plate, the bottom of the elastic plate 7 is rotatably connected with a rubber column 8, so that the middle of a workpiece can be conveniently contracted during punching, the workpiece can be inwardly gathered and slide, the friction force generated by the elastic plate 7 is reduced, two ends of the elastic plate 7 are both provided with clamping connecting rods 9, each end in base plate 1 bottom sets up two joint grooves 91 at least, and joint pole 9 can the chucking in joint groove 91.

Specifically, 2 upside fixed connection sleeve pipes 21 of moulding-die, inside square pole 11's lower extreme stretched into sleeve pipe 21, the sleeve pipe 21 outside was equipped with the screw hole, and screw hole intercommunication sleeve pipe 21 is inside to be set up, screw hole internal thread connection check lock lever 22, check lock lever 22's end can support tight square pole 11, and check lock lever 22 is loosened soon and can be taken off moulding-die 2, is convenient for change the moulding-die 2 of different models.
