Abstract

The utility model provides a punching die, including cope match -plate pattern, upper padding plate, lower bolster, lower bolster, first terrace die and second terrace die, be fixed with first die on the cope match -plate pattern, be fixed with the second die on the lower bolster, first terrace die is fixed on the cope match -plate pattern, the second terrace die is fixed on the lower bolster, be equipped with a plurality of firstly towards the needle on the first terrace die, be equipped with a plurality of seconds towards needle on the second terrace die. The utility model has the advantages of with positive effect be: the utility model discloses a first die and second die elder generation subtend compress tightly by the stamping workpiece, then successively carry out the punching press to the stamping workpiece through first terrace die and second die, do not have the burr after the part punching press, have reduced the man -hour and the cost of punching press.

Description

A kind of punching die

Technical field

The utility model relates to injection-moulding device technical field, particularly relates to a kind of punching die.

Background technology

Mould, as the one of the high efficiency tool of production, is use in industrial production very extensively and important technological equipment.Red needle mould be comparatively common in mould, use more one, punch on parts according to actual needs after parts have been produced, so that subsequent installation operation, therefore the quality of red needle mould is related to the precision of punching, and then is related to quality and the subsequent installation of parts.

At present, current much stamping parts technique all requires impulse-free robustness, and part needs to increase deburring operation after punching press, thus adds man-hour and the cost of stamping.

Utility model content

Problem to be solved in the utility model is to provide a kind of punching die, and red needle precision is high, does not have burr, reduces man-hour and the cost of punching press.。

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of punching die, comprises cope match-plate pattern, upper padding plate, lower bolster, lower bolster, the first punch and the second punch, described cope match-plate pattern is fixed with the first die, described lower bolster is fixed with the second die, described first punch is fixed on described cope match-plate pattern, and described second punch is fixed on described lower bolster, described first punch is provided with some first red needles, and described second punch is provided with some second red needles.

Further, described first punch comprises die shank, and described upper die shank lower end is connected with terminal pad, and described first red needle is positioned at described upper terminal pad lower surface; Described second punch comprises lower die shank, and described lower die shank upper end is connected with lower terminal pad, and described second red needle is positioned at described lower terminal pad upper surface.

Further, described cope match-plate pattern is provided with the fairlead for described first punch guiding, described upper die shank is through described fairlead, and described upper terminal pad is placed in the die cavity that described fairlead and described cope match-plate pattern are formed.

Further, the two ends of described cope match-plate pattern lower surface are provided with positioning convex, and on described lower bolster, correspondence is provided with the positioning sleeve matched with it.

Further, the two ends of described lower bolster upper surface are provided with pillar, and described positioning sleeve is positioned at the upper surface of described pillar.

The advantage that the utility model has and good effect are:

(1) the utility model compresses by the first die and the first subtend of the second die the part that is stamped, and then successively carries out punching press to stamping parts by the first punch and the second die, does not have burr, reduce man-hour and the cost of punching press after part punching.

(2) two ends of cope match-plate pattern lower surface are provided with positioning convex, correspondingly on lower bolster are provided with the positioning sleeve matched with it, more accurate when making punching, improve punching precision.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

In figure:

1, the first die; 2, the second die; 3, cope match-plate pattern; 4, lower bolster; 5, upper die shank; 6, upper terminal pad; 7, the first red needle; 8, upper padding plate; 9, fairlead; 10, lower bolster; 11, lower die shank; 12, lower terminal pad; 13, the second red needle; 14, positioning convex; 15, positioning sleeve; 16, pillar

Detailed description of the invention

Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.

As shown in Figure 1: a kind of punching die, comprise cope match-plate pattern 3, upper padding plate 8, lower bolster 4, lower bolster 10, first punch and the second punch, described cope match-plate pattern 3 is fixed with the first die 1, described lower bolster 4 is fixed with the second die 2, described first punch is fixed on described cope match-plate pattern 3, described second punch is fixed on described lower bolster 4, and described first punch is provided with some first red needles 7, and described second punch is provided with some second red needles 13.

In the present embodiment, described first punch comprises die shank 5, and described upper die shank 5 lower end is connected with terminal pad 6, and described first red needle 7 is positioned at described upper terminal pad 6 lower surface; Described second punch comprises lower die shank 11, and described lower die shank 11 upper end is connected with lower terminal pad 12, and described second red needle 13 is positioned at described lower terminal pad 6 upper surface.

Further, described cope match-plate pattern 3 is provided with the fairlead 9 for described first punch guiding, described upper die shank 5 is through described fairlead 9, and described upper terminal pad 6 is placed in the die cavity that described fairlead 9 is formed with described cope match-plate pattern 3.

The two ends of described cope match-plate pattern 3 lower surface are provided with positioning convex 14, and on described lower bolster 10, correspondence is provided with the positioning sleeve 15 matched with it.In an embodiment of the present utility model, the two ends of described lower bolster 10 upper surface are provided with pillar 16, and described positioning sleeve 15 is positioned at the upper surface of described pillar 16.

During punching press, first die 1 and the first subtend of the second die 2 compress the part that is stamped, then the first punch does incomplete punching press through the second die 2 endoporus, after first punch resets, second punch carries out punching press through the endoporus of the first die 1 to same punching position, after second punch resets, the first die 1 and the second die 2 unclamp the part that is stamped.

Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model scope change and improve, and all should still belong within this patent covering scope.
