Abstract
An upper mould of a porous mould relates to an improved upper mould structure of a porous mould which is capable of simultaneously processing multiple slotted holes during one punching and bringing convenience for realizing separation between a pressure plate and an upper mould shank without affection onto the outer cylindrical surface of the upper mould. The upper mould comprises the upper mould shank, at least two punches, a guide pin and the pressure plate, the pressure plate is provided with mounting holes matched with the punches, the punches are arranged in the mounting holes, the pressure plate is fixedly connected to the bottom surface of the upper mould shank by positioning pins and screws, the guide pin is arranged on the side of the upper mould shank, a through slot running through the top surface of the pressure plate radially is arranged on the top surface of the pressure plate, and the mounting holes are disposed on the bottom surface of the through slot. Since the pressure plate of the punches is designed into the through-slot type, the upper mould can be detached conveniently, and the trouble of milling steps for a fixing hole of each punch is omitted. In addition, the punches can be positioned accurately, while the pressure plate can be separated from the upper mould shank conveniently from a notch of the through slot when in detachment of the pressure plate.
Description
Technical field
The present invention relates to improvement to the last mode structure of the porous mold that processes a plurality of hole slots in the punching press simultaneously.
Background technology
In the prior art, unskilled labourer position multiple-hole die comprises upper and lower core rod on the thin rotating tower punch of numerical control, and patrix is made up of last die shank, alignment pin, drift fixed head (pressing plate) and drift, and counterdie is by mould body and alignment pin are formed down.
At present, patrix all is whole spark machined drift, and electric spark will be used expensive red copper electrode, just scraps after the processing, and the client uses drift to break in addition or the whole patrix that weares and teares is just scrapped, and has waste.Existing make patrix split type, the drift use interrupted or wear and tear after can directly change drift, can use, practiced thrift very big cost.Even if but split type, because that last mould assembly bears axial load at work is big, when making dismounting; Although unload except attachment screw; But pressing plate still is difficult to break away from from last die shank bottom surface, prizes from outer surface, and very easily the surface quality of mould assembly cylinder is gone up in influence.And go up the requirement that mould assembly outer surface (cylinder) often has guiding to cooperate, in case the trace of sticking up is arranged, strike trace, the precision of just influence guiding is when serious even can damage the outer surface of die shank and the inner surface of outside guide pin bushing.
Summary of the invention
The present invention is directed to above problem, provide a kind of pressing plate and last die shank of making things convenient for to break away from, and can not influence the patrix of the multiple-hole die of patrix outer cylinder.
Technical scheme of the present invention is: comprise die shank, at least two drifts, guide finger and pressing plates; Offer the installing hole adaptive on the said pressing plate with said drift; Said drift is located in the installing hole, and said pressing plate is fixedly connected on the bottom surface of said upward die shank through alignment pin and screw again, and said guide finger is located at said side of going up die shank; Offer on the end face of said pressing plate from radially connecting the groove of said pressing plate end face, said mounting hole site is on the bottom surface of said groove.
The present invention becomes the groove formula with the drift platen design, greatly makes things convenient for the patrix dismounting, has also saved the trouble that each drift fixing hole all will mill step.Can accurately locate each drift on the one hand, when the dismounting pressing plate, can pressing plate separated with last die shank on the other hand.

The specific embodiment
The present invention is shown in Fig. 1-5; Comprise die shank 1, at least two drifts 4, guide finger 5 and pressing plates 3; Offer the installing hole 40 adaptive on the said pressing plate 3 with said drift 4; Said drift 4 is located in the installing hole 40, and said pressing plate 3 is fixedly connected on the bottom surface of said upward die shank 1 through alignment pin 2 and screw 6 again, and said guide finger 5 is located at said side of going up die shank 1; Offer on the end face of said pressing plate 3 from the groove 30 that radially connects said pressing plate end face, said installing hole 40 is positioned on the bottom surface of said groove 30.
During making, on the bottom surface of last die shank 1, offer dowel hole 2 21, screw connecting hole 61.
On the step of groove 30 sides on the pressing plate 3, offer a pair of dowel hole 1; On the bottom surface of groove 30, offer the drift installing hole 40 and screw hole 60 that connect pressing plate 3.
Claims (1)
