Description
Technical field
The present invention relates to field of automobile, and in particular to a kind of mould of form stable.
Background technology
Drawing is one of important forming method of sheet-metal parts, and blank holder is one of strength member in drawing die again.
Blank holder is as movable part, and its typical guidance mode is that guide plate is oriented to and guide pillar is oriented to, and guide plate guiding applies in general to large-scale
Casting drawing die, guide plate, which is oriented to have, preferably prevents lateral ability.Guide pillar is oriented to and applies in general to small-sized steel plate mould, guide pillar
It is weaker to be oriented to counteracting to side force, particularly blank holder stroke it is bigger in the case of it is weaker.But due to surrounding during drawing
The charging rate of plate is different, resistance not exclusively, it is even to hand over that often blank holder, which has different degrees of side force,
Become side force.After certain batch production, due to side force, blank holder guide pillar clamping stagnation, guiding accuracy drop are easily caused
It is low, or even cause the unstable of drawing element precision.
In addition, existing mould structure is complicated, and product is not easy quickly to remove, and influences procedure production.
The content of the invention
For the deficiency in the presence of prior art, the invention provides a kind of mould of form stable, solves drawing
The problem of mould structure is complicated, service efficiency is low.
To achieve the above object, present invention employs following technical scheme：A kind of mould of form stable, including upper mould
Plate and lower mould bottom plate,
Cope plate is connected with cavity plate, and Upper shaft sleeve is provided with the cope plate of cavity plate both sides, fluted, groove is set on cavity plate
Surrounding is provided with locating slot；
Lower mould bottom plate is connected with reinforcing plate, and lower template is provided with reinforcing plate, and the middle part surface of lower template is provided with lower mould
Mechanism, Lower shaft sleeve is provided with the lower template of lower die mechanism both sides, the axis of guide, the axis of guide and the upper axle are fixed with Lower shaft sleeve
Set is engaged fixation, the direction of motion of fixed cope plate；
Lower die mechanism includes sole piece, punch-pin, spring, alignment pin, edge-pressing board and locating shaft, and punch-pin is arranged at the middle part of sole piece
Surface, sole piece are arranged in lower template, and through hole is provided with sole piece, and the locating shaft sequentially passes through lower mould bottom plate, lower template, led to
Hole and edge-pressing board, locating shaft are fixed on lower mould bottom plate, and locating shaft is flexibly connected with lower template, through hole and edge-pressing board；The pressure
Side plate is provided with preformed hole, and the punch-pin passes through preformed hole；The spring is located in through hole and is sheathed on locating shaft, the external diameter of spring
Match with the internal diameter of through hole, the diameter of the locating shaft in through hole and the internal diameter of spring match；
The alignment pin is arranged on edge-pressing board, is engaged with locating slot；The drift value of the spring is more than through hole
Depth value.
Further, it is additionally provided with distance measuring sensor in the cope plate and lower mould bottom plate.
Further, cylinder is additionally provided with sole piece.
Further, the number of through hole is 4, and 4 through holes are distributed in the surrounding of punch-pin.
Further, the junction of axle sleeve and cope plate is provided with adjustment hole.
Compared to prior art, the present invention has the advantages that：The scheme for the solution technical problem that this programme provides
Simply, it is practical, solve the problem of drawing mold structure is complicated, eliminates the ad hoc detent mechanism of edge-pressing board, and service efficiency is low.
Edge-pressing board sets alignment pin, and the counterbore and screw of the logical interference fit of alignment pin are arranged on edge-pressing board, and cavity plate is corresponding
The locating slot matched somebody with somebody with alignment pin into slip is set.When cavity plate starts to contact with edge-pressing board, alignment pin is corresponding with cavity plate
Locating slot coordinates, and among the process of drawing, ensures that the relative position of edge-pressing board and cavity plate does not change, exists so as to eliminate edge-pressing board
Caused unbalanced side force in drawing process.
The setting of spring makes mould structure carry energy storing members, can more preferably workpiece break away from moulds, edge-pressing board and locating shaft
The requirement that axle makes precision can be reduced by being flexibly connected, and reduce cost, and the cooperation of alignment pin and locating slot can make punch-pin
With cavity plate fast positioning.
Be additionally provided with sole piece cylinder easily the stroke of edge-pressing board can be entered it is spacing.Adjustment hole increases stroke, can be with
The workpiece of Multiple Type is processed, expands use range.
