Abstract

The utility model discloses an automatic chip falling punch mold formed by molding and pressing hard alloy powder. According to the mold, a circle of ring-shaped groove is formed in a sliding face of a punch below the mold, and material peel attachments generated in the process of molding and pressing the hard alloy powder is automatically scraped into the ring-shaped groove. Gathering of material peels in a mold cavity is reduced, and a chip falling vertical groove communicated with the ring-shaped groove is formed in the lower portion of the ring-shaped groove. The material peel attachments in the ring-shaped groove can automatically fall down and are dropped out from the chip falling vertical groove. According to the automatic chip falling punch mold formed by molding and pressing the hard alloy powder, the material peels can be automatically removed in the processing of molding and pressing the hard alloy powder, influences on molding of products by the material peel attachments are eliminated, trouble in cleaning the material peel attachments by manual work is avoided, and production efficiency is improved.

Description

A kind ofly fall to consider to be worth doing plunger chip die automatically

Technical field

The utility model belongs to a kind of equipment for the cemented carbide powder compression molding.Be specifically related to a kind of mould of moulding compacting.

Background technology

In the cemented carbide powder molding production process, normally powder is filled in the pressing mold, utilize impressed pressure to carry out stamping of powder.In order to satisfy the density requirements of goods, adopt bidirectional pressed moulding, by the interoperation of powder metallurgy hydraulic press and mould, different metal or alloy powder are pressed into the part with certain size shape, density and intensity.

The mould that adopts in the existing bidirectional pressed moulding is sandwich construction, is disclosed " fast quick-mounting mould mould " in 2012202494765 the Chinese patent as the patent No..Its top is rush-up seat, and upper punch is fixed in the rush-up seat, and the middle part is the former seat, be fixed together by four guide pillars with workbench, its fixed in space arranges down red seat between former seat and the workbench, and low punch is arranged on down in the red seat, in pressing process, following red seat maintains static, and hydraulic press drives rush-up seat, the former seat is connected with the workbench core bar, moves reciprocatingly, by the top and the bottom pressurization, realize the bidirectional pressed moulding of goods.

The defective of this mould is:

1, because drift is matched in clearance with cooperating of die body, in the process of moulding, low punch is done back and forth movement in die cavity, gap between low punch and the die cavity inevitably can fall into the material powder, become the material skin during compacting, these material skins accumulate on the low punch sliding surface, have influenced the stability of pressing process and the moulding of product.

2, the sliding surface of mould has determined the vertical precision of mould assembling, need certain length to guarantee assembly precision, because the gathering of material skin attachment and be difficult in die cavity, discharging, thereby influence resetting of mould, must adjust press in process of production, mould is carried out the labor cleaning, waste time and energy, reduced production efficiency.

The utility model content

The purpose of this utility model be to provide a kind of can will expect in cemented carbide powder moulding pressing process that skin removes automatically fall to consider to be worth doing plunger chip die automatically.

The technical solution of the utility model is as follows:

A kind ofly fall to consider to be worth doing plunger chip die automatically, comprise rush-up seat, former seat and following red seat; Upper punch is fixed in the rush-up seat; Former is fixed in the former seat; Be provided with material cavity in the former; Low punch is fixed on down in the red seat, and described to fall to consider to be worth doing plunger chip die automatically be that sliding surface at low punch is provided with annular groove; Be provided with in the bottom of annular groove communicate with annular groove consider to be worth doing vertical slot.

The sliding surface of described low punch refers to the mating surface of low punch and former.

Described low punch is matched in clearance with cooperating of former.

Describedly fall to consider to be worth doing vertical slot and arrange five at least around annular groove, its top communicates with annular groove.

In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:

1, owing to the sliding surface at low punch is provided with annular groove, the material skin attachment that produces in the cemented carbide powder moulding pressing process is scraped in the annular groove automatically, reduced the gathering of material skin in the die cavity, eliminated the influence of material skin attachment to formed product.

2, since be provided with in the bottom of annular groove communicate with annular groove consider to be worth doing vertical slot, the material skin attachment in the annular groove is dropped from falling to consider to be worth doing vertical slot automatically.Both guaranteed the assembling vertical precision of mould, the attachment that the low punch sliding surface is assembled drops automatically, has avoided the loaded down with trivial details of labor cleaning, has improved production efficiency.

Description of drawings

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

Fig. 2 is the structural representation that falls to consider to be worth doing drift automatically of the present utility model.

Fig. 3 is that the A-A of Fig. 2 is to view.

Among the figure: 1, rush-up seat; 2, upper punch; 3, former; 4, material cavity; 5, former seat; 6, annular groove; 7, fall to consider to be worth doing vertical slot; 8, low punch; 9, following red seat

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in detail:

As shown in Figure 1 and Figure 2, the utility model by rush-up seat 1, upper punch 2, former 3, material cavity 4, former seat 5, annular groove 6, fall to consider to be worth doing vertical slot 7, low punch 8 and following red seat 9 and form.

Upper punch 2 is fixed in the rush-up seat 1, and former 3 is fixed in the former seat 5, is provided with material cavity 4 in the former 3, and low punch 8 is fixed on down in the red seat 9.Sliding surface at low punch 8 is provided with annular groove 6; Low punch 8 is matched in clearance with former 3, and the sliding surface of low punch 8 refers to the mating surface of low punch 8 and former 3.Be provided with in the bottom of annular groove 6 communicate with annular groove 6 consider to be worth doing vertical slot 7.Fall to consider to be worth doing vertical slot 7 and arrange five at least around annular groove, its top communicates with annular groove 6.In the process of compression moulding, because the back and forth movement of former seat 5 is scraped in the annular groove 6 the material skin that produces in the cemented carbide powder moulding pressing process automatically, and drop and take out of from the vertical slot 7 that consider to be worth doing that communicates with annular groove 6 automatically.

Verify through actual production: the utility model has solved the problem that the drift attachment is assembled preferably, has avoided producing the loaded down with trivial details of material skin in labor cleaning's pressing process, has improved production efficiency.

The above only is preferred embodiment of the present utility model, all any modifications of doing within spirit of the present utility model and principle, is equal to and replaces and improvement etc., all should be included within the protection domain of the present utility model.
