Description

Multiple chip punch retainer and have the mould of this fixture

Technical field

The utility model is about a kind of multiple chip punch retainer and has the mould of this fixture.

Background technology

The production of covering at present is most of adopts the mould punch forming, and the shape hole on the product also adopts punch punching mode to go out, and reason is that the production cost of this mode is low, and fund input is few.But for air-conditioning spare, because part is less, and the part profile is smooth, and the shape hole is many, and this shape hole mostly is the Long Circle hole greatly, and arranges comparatively compactness between the Kong Yukong, and more typical product is the heat radiation film perforation (as shown in Figure 1) on the air-conditioning.When dashing with the punching mode when getting the air-conditioning heat dissipation film perforation, its shortcoming is also clearly: because punching needs backing plate and fixed head, and so many drift so is closely aligned together, can only allow the shared fixed head of all drifts, because the distance between the wide and Kong Yukong in hole is very little, adopt the mode of hanging platform that drift is fixed on the drift fixed head, long-time use, the as easy as rolling off a log damage of drift, processing cost is increased, and with bolt drift is fixed on the drift fixed head, also be not suitable for, so, how many like this drifts are fixed on the drift fixed head, they can be used when work for a long time, be not easy again to damage, also just become a difficult problem.

The utility model content

The purpose of this utility model is that to overcome product shape hole count many, and distance between borehole is little, and the piercing punch shortcoming that is difficult to fix, thereby a kind of new multiple chip punch retainer is provided and has the mould of this fixture.

The multiple chip punch retainer that the utility model provides comprises punch retainer and punch, a plurality of through holes that the upper surface of punch retainer has same direction to arrange, a plurality of punch are arranged in a plurality of through holes, this multiple chip punch retainer also comprises core bar and through hole, through hole and a plurality of through hole intersect and run through punch retainer and punch upper end, and the core bar penetrates in the through hole.

The mould that has this fixture that the utility model provides, this mould comprises upper die and lower die and multiple chip punch retainer, multiple chip punch retainer is fixed on the patrix, wherein, and the multiple chip punch retainer that described multiple chip punch retainer provides for the utility model.

Adopt hanging platform mode solid punch (drift) on the existing fixed head, because of the existence of hanging platform, the hole broad, and the distance between the Kong Yukong is less, in long-time use, the part that punch (drift) contacts with hanging platform is damaged easily.And the multiple chip punch retainer of the utility model does not have hanging platform, but punch is fixed on the punch retainer by a core bar, and the problem that punch (drift) does not contact with hanging platform yet is therefore, not fragile.From the multiple chip punch retainer of above-mentioned the utility model structure as can be seen, the multiple chip punch retainer of the utility model also has simple in structure, and cost easy to manufacture is low, the advantage of high efficiency.

The specific embodiment

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

As shown in Figure 2, the multiple chip punch retainer of the utility model comprises punch retainer 1 and punch 2, a plurality of through holes 3 that punch retainer 1 upper surface has same direction to arrange, a plurality of punch 2 are arranged in a plurality of through holes 3, this multiple chip punch retainer also comprises core bar 4 and through hole 5, through hole 5 intersects with a plurality of through holes 3 and runs through punch retainer 1 and punch 2 upper ends, and core bar 4 penetrates in the through hole 5.

As shown in Figure 3, a plurality of through holes 3 that described punch retainer 1 upper surface has same direction to arrange, through hole 5 intersects with a plurality of through holes 3 and runs through punch retainer 1, and through hole 5 can have any shape, as rectangle, circle or oval.

As shown in Figure 4, described punch 2 is plates, and punch 2 shape of cross sections are identical with institute pressing product hole shape, and through hole 5 runs through punch 2 upper ends.

As shown in Figure 5, described core bar 4 is a strip, the shape of core bar 4 cross sections can be an arbitrary shape, as circular, square or ellipse etc., at least one end of core bar 4 is fixedlyed connected with punch retainer 1, fixedly connected mode is as well known to those skilled in the art, as welding, be threaded or the bending of core bar 4 two ends.

Owing to adopt the multiple chip punch retainer of the utility model, on the basis that does not influence the punch moulding, punch is fixed in the punch retainer by a core bar, simple in structure, low cost of manufacture, and high efficiency.
