In order to solve the technical problems, the utility model adopts a technical scheme that: the utility model provides a punching press appearance and hole burr syntropy mould, includes mould, upper padding plate, lower mould and lower bolster, the lower bolster top is provided with the terrace die that punches a hole, the upper padding plate below is provided with towards the appearance terrace die, be provided with on the appearance terrace die with the terrace die that punches a hole is in the groove of wasting discharge of same vertical direction, the upper padding plate transversely link up and is provided with the channel of wasting discharge, the groove of wasting discharge with the channel of wasting discharge is linked together, one side of the channel of wasting discharge is provided with air supply device, the opposite side of wasting discharge channel is provided with storage device.

Preferably, the cross-sectional width of the waste discharge channel towards one side of the air supply device is smaller than the cross-sectional width of the waste discharge channel towards one side of the accommodating device.

Preferably, the air supply device is a blower.

Preferably, the receiving device includes a guide tube connected to the waste basket.

Preferably, the sliding clearance between the punching male die and the waste discharge groove is 0.01mm-0.02 mm.

The utility model has the beneficial effects that: according to the die with the same punching appearance and the hole burrs, the punching male die is arranged on the lower die, the punching outer male die is arranged on the upper die, the upper die and the lower die are matched for punching, the same direction of the punched product appearance and the hole burrs is realized, waste materials are collected by utilizing air flow guiding, the process flow is short, the production efficiency is high, the product turnover transfer is not needed, the die is punched in one step, the structure is simple and ingenious, and the die has good practicability.

Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the utility model.

Example (b):

as shown in fig. 3, a die with a stamping shape and holes and burrs in the same direction comprises an upper die 1, an upper backing plate 2, a lower die 3 and a lower backing plate 4, which form the basic structure of the die and are common in the industry and are not described again. A punching male die 5 is arranged above the lower base plate 4, and is used for punching upwards during operation to ensure that the direction of a burr surface is upwards; the outer punching male die 6 is arranged below the upper padding plate 2, the outer punching male die 6 is punched downwards during operation, the directions of burrs 12 generated during outer punching and burrs 12 in holes are in the same plane, the directions of the burrs of the punched rear reinforcing plate product are shown in fig. 4, the burrs of the punched FPC reinforcing plate face the non-adhesive surface, and the soft plate can be effectively prevented from being damaged by the burrs.
