Abstract

The utility model relates to an easily-discharged mould which is characterized in that the easily-discharged mould comprises an upper mould and a lower mould, wherein the upper mould comprises a punch and a discharging plate sleeved outside the punch and matched with a lower mould structure; an elastic jacking piece capable of lifting relative to the discharging plate and moving to a position at which the elastic jacking piece partially is exposed outside the bottom surface of the discharging plate or completely contracts into a discharging plate body is installed at the bottom of the discharging plate; and when the mould is not closed, the elastic jacking piece is partially exposed outside the bottom surface of the discharging plate. The utility model aims at providing the easily-discharged mould which can effectively prevent workpeice from being adhered onto the discharging plate and ensure the orderly discharging.

Description

Be prone to the mould of discharging

Technical field

The utility model relates to a kind of mould of easy discharging.

Background technology

Punch process is one of basic skills of Metal Forming.In order to make stamping forming workpiece break away from patrix, so that mould ability operate as normal adopts stripper to carry out the discharging operation usually.But owing to be attached with lubricating oil on stripper or the workpiece, when carrying out punching press, workpiece possibly stick on the stripper, causes automatic discharging failure, needs manual work to unload workpiece, reduces production efficiency.

Summary of the invention

The purpose of the utility model is to provide a kind of mould of easy discharging, and it can prevent effectively that workpiece from sticking on the stripper, and the assurance discharging is carried out in order.

The purpose of the utility model realizes through following technical scheme: a kind of mould of easy discharging is characterized in that: it comprises patrix and counterdie, and said patrix comprises drift and is sheathed on the stripper that drift is outer and match with following mode structure; The bottom of said stripper is equipped with relatively stripper lifting moving to part and is exposed the stripper bottom surface or collapse into the elastic top push piece in the discharging plate body fully, and the elastic top push piece partly exposes the stripper bottom surface when matched moulds not.

The operation principle of the utility model: during the punch die matched moulds, the elastic top push piece is made the elastic top push piece collapse into fully in the discharging plate body by the blank roof pressure; When punch die divided mould, the stamping forming workpiece of elastic top push piece pushing tow made workpiece separate with stripper, thereby workpiece is realized discharging under the promotion of stripper and elastic top push piece.

Compared to prior art, the advantage of the utility model is: through the elastic top push piece is set on stripper, can prevent effectively that workpiece from sticking on the stripper, the assurance discharging is carried out in order.

The specific embodiment

Below in conjunction with Figure of description and embodiment the utility model content is elaborated:

Like the embodiment sketch map of Fig. 1 to the mould of a kind of easy discharging that provides for the utility model shown in Figure 3.It comprises patrix and counterdie 2, and said patrix comprises drift 1 and is sheathed on outside the drift 1 and the stripper 3 that matches with counterdie 2 structures; The bottom of said stripper 3 is equipped with relatively stripper 3 lifting moving to part and is exposed stripper 3 bottom surfaces or collapse into the elastic top push piece 4 in stripper 3 bodies fully, and elastic top push piece 4 parts are exposed stripper 3 bottom surfaces when matched moulds not.

Said elastic top push piece 4 by ball and be connected in ball and stripper 3 between back-moving spring constitute; Stripper 3 bottoms are provided with the perpendicular duct of putting that is used for installing ball and back-moving spring; When matched moulds not, ball exposes the bottom surface of stripper 3 in the action of reset spring lower part.

Claims
