Abstract

The utility model discloses a die floatation mechanism. The die floatation mechanism comprises a cavity die, a material supporting block which can slide upward and downward, and a die holder. A float mosaic block is imbedded between the upper part of the material supporting block and the corresponding part of the sagged part of the cavity die, and the float mosaic block can slide upward and downward. The utility model can change the fixed structure of the male die to the floating structure, and then the arrangement of the elastic element is not limited for the shape of the workpiece. The workpiece which is required to be completed on many sets of dies before, is able to be completed on a set of die now, which spares the numbers of the die. The material supporting block is embedded with the float mosaic block, which causes the utility model to be with simple structure and to reduce the manufacturing cost of the utility model.

Description

A kind of mould relocation mechanism

Technical field

The utility model relates to technical field of mold, is specifically related to a kind of mould relocation mechanism.

Background technology

In the existing mold, when needs to product to upper overturning or when being shaped, the conventional structure of stamping die as shown in Figure 1, to carry out the punch of flange or shaping and die shoe 1 usefulness screw or pin to product tightens together, make and do not have relative motion between the two, need flexible members such as spring or air cushion under the mould retainer piece 2 is carried out retainer, the flexible member among Fig. 1 is a pressure pin 6.As shown in Figure 2, when die 3 moved downward under the effect of stamping die slide block, the elastic force that overcomes pressure pin 6 moved downward retainer piece 2, produces relative motion between retainer piece 2 and the punch 9, finishes the flange or the forming process of product.But for the product of some shape more complicated, the content of inner flange of product or shaping is a lot, and the layout of flexible member is restricted, and will increase number of molds usually, finishes the processing of product respectively in several molds.Therefore some large-scale covering has limited the size range of mould design because drawn component is very big, and its blank holder has surpassed the scope of existing stamping die flexible member effect.

The utility model content

Technical problem to be solved in the utility model is the above-mentioned deficiency at prior art, provides a kind of layout of flexible member that can make not to be subjected to the influence of product shape, thereby realize the mould relocation mechanism of different product processing requests on a mold.

Solving the technical scheme that the utility model technical problem adopted is this mould relocation mechanism, comprises die, can slide up and down retainer piece, die shoe, is embedded with can fluctuate unsteady in the depressed part corresponding position of retainer piece top and die and inserts.

Should float to insert and realize the characteristic that it fluctuates: on the first retainer piece through hole be arranged by two kinds of structures, this through hole be located at float insert under, through hole is built-in with support bar, and through hole top is provided with symmetrical boss near the place of inserting of floating, and the head of support bar places the boss top; Its two be have a through hole, this through hole to be located on the retainer piece to float insert under, through hole is built-in with support bar, support bar is fixed on the die shoe.

The utility model changes punch into floating structure by fixed structure, thereby the layout of flexible member is not restricted because of the product shape, make and just can finish on a mold in the product processing of finishing on many molds originally, so just saved number of molds.The utility model is inlayed the form of inserting of floating by employing and is changed punch into floating structure by fixed structure on the retainer piece, this is simple in structure, low cost of manufacture.

Among the figure: 1-die shoe 2-retainer piece 3-die 4-support bar 5-guide plate 6-pressure pin 7-material returned screw 8, the unsteady 12-through hole 13-boss of inserting of 11-screw 9-punch 10-

The specific embodiment

Embodiment 1:

As shown in Figure 3, the utility model comprises die 3, the retainer piece 2 that can slide up and down, die shoe 1, being embedded with on retainer piece 2 tops floats inserts 10, one through hole 12 is arranged at the bottom of retainer piece 2, through hole 12 float insert 10 under, support bar 4 is arranged in the through hole 12, support bar 4 not with float insert 10 fixing, through hole top is provided with symmetrical boss 13 near unsteady 10 parts of inserting, and the head of support bar 4 places the top of boss 13.Present embodiment is applicable to the not high situation of product flange precision, and also being applicable to floats inserts 10 not quite, does not have the situation of enough fixed in space support bars 4.

Embodiment 2:

As shown in Figure 4, the structural similarity in the present embodiment among the structure of mould relocation mechanism and the embodiment 1, difference is that the head of support bar 4 is fixed in to float by screw 11 and inserts on 10.

Embodiment 3:

As shown in Figure 5, a through hole 12 is arranged on the retainer piece 2 in the present embodiment, through hole 12 float insert 10 under, support bar 4 is arranged in the through hole 12, support bar 4 is fixed on the die shoe 1 by screw 8.

The utility model course of work is as follows: at the beginning of punch press started, retainer piece 2 and unsteady 10 whiles of inserting on it moved downward under the promotion of die 3, and retainer piece 2 slides in the guide rail 5 of die shoe 1 by guide plate 5.Insert when floating and 10 to float when touching support bar 4 to insert and 10 no longer move downward, and retainer piece 2 continues to move downward under the promotion of die 3, die 3 10 contacts the punching press of finishing product with floating to insert, then die 3 promotion retainer pieces 2 move to after bottom dead center, die 3 begins to move upward, retainer piece 2 is got back to initial point under the promotion of air cushion pressure pin 6, finish a punching press.
