technical field

The utility model relates to the field of stamping dies, in particular to a stamping die with a jacking device.

Background technique

Stamping dies are tools made of metal and other rigid materials for stamping and forming. Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. Stamping die is an indispensable process equipment for stamping production, and it is a technology-intensive product. The quality, production efficiency and production cost of stamping parts are directly related to the design and manufacture of molds.

In the production of large-scale metal stamping parts, after the upper and lower molds complete the stamping action, during the process of returning and lifting the upper mold, the stamping plate formed by the mold is sometimes adsorbed on the upper mold, and slips after a period of movement. It is very easy to cause scratches on the stamping plate, which affects the processing quality of the parts.

detailed description

The technical scheme of the present utility model is described below in conjunction with accompanying drawing and embodiment.

With reference to Fig. 1 shown, a kind of stamping mold with ejector device comprises die 12 and punch 6, and described punch 6 is fixedly arranged on the bottom surface of upper mold base 1, and in the middle concave cavity of described punch 6 The upper pressing block 7 is fixedly arranged, and the die 12 is fixedly arranged on the top surface of the lower mold base 17. The top of the die cutout 4 of the die die 12 has a tapered flare 3, and the space enclosed in the middle of the die cutout 4 A lower backing plate 10 is provided in the cavity, and the lower backing plate 10 floats up and down in the cavity, and the bottom is provided with a first return spring 5, and a plurality of grooves 8 are arranged on the lower backing plate 10, and the grooves Correspondingly be provided with ejecting device 9 in 8. The top surface of the lower backing plate 10 is higher than the end surface of the die slit 4 of the die 12 . A thin positioning frame plate 18 is fixed on the end face of the punching opening 4 of the die 12, and a positioning window 2 is arranged in the middle of the thin positioning frame plate 18. Dimensions are equal to the overall dimensions of the workpiece. Through the setting of the positioning window 2, the deflection of the workpiece during the punching process is avoided, thereby ensuring the punching accuracy.

The lower mold base 17 is provided with an air gun device matched with the ejector device 9 . The air gun device includes a lifting base 11 and an air gun 19 arranged on the lifting base 11 , and the mouth of the air gun 19 is matched with the ejecting device 9 . The lifting seat 11 can be lifted and adjusted according to the height of the stamping workpiece, so as to ensure that the air gun mouth can cooperate with the ejecting device 9 at any time.

Referring to Fig. 1 and shown in Fig. 3, ejector device 9 comprises fixed seat 15, ejector rod 14 and the second return spring 16 that is arranged between fixed seat 15 and ejector rod 14; The top surface of described ejector rod 14 is higher than The top surface of the lower backing plate 10. In the process of pressing down the upper die base 1, driven by the upper pressure, the ejector rod 14 shrinks into the groove 8, and at the same time compresses the second return spring 16; after the stamping action is completed, the upper die base 1 is lifted, and Under the action of the elastic recovery force of the two back-moving springs 16, the top surface of the push rod 14 is reset to a position higher than the top surface of the lower backing plate 10, thereby forcing the workpiece to be unable to be absorbed by the upper die base 1, and to stay in the lower backing plate 10 for a predetermined time. Position, but also to avoid damage to the workpiece caused by the adsorption of the upper die base 1.

The operating principle of the utility model is: when the upper pressing block 7 is pressed down, the lower backing plate 10 is forced to move downward in the cavity, and at the same time, the ejector rod 14 also moves downward in the groove 8 driven by the pressure, After the stamping action is completed, the upper pressing block 7 rises, the lower backing plate 10 is reset under the reset force of the first return spring 5, and the ejector rod 14 is reset under the active force of the second return spring 16, because the ejector rod 14 The top surface of the lower base plate 10 is higher than the top surface of the lower backing plate 10, so the ejector rod 14 directly lifts the workpiece, and the air gun device arranged on the lower mold base 17 is activated to blow away the workpiece lifted by the ejector rod 14 according to the set direction. , that is to complete a stamping process.
