Abstract
The utility model relates to a mold structure, especially a novel internal diameter orthodrome carbide product forming die structure, the bed die, the upper punch, the core bar is gone up to the low punch, and lower core bar is formed, on pipe shape bed die assembled the low punch, the little outer diametral plane of bed die hole and low punch coordinated, the upper punch just sets up in the product top in assembling the bed die, going up the core bar, to assemble the upper punch downthehole, go up the core bar be equipped with outward the orthodrome and with core bar looks sliding fit's little cylinder down, down to assemble the low punch downthehole for the core bar, and lower core bar has the orthodrome outward has through -hole and the cooperation of last core bar in, bed die hole, upper punch lower extreme, go up core bar outside circular arc, lower core bar outside circular arc, the clearance space that the low punch upper end constitutes is product shaping position, utility model technical scheme reaches complete shaping orthodrome, and the product hole does not have straight section, burr, and mould durable is difficult to damage.
Description
Technical field
The utility model relates to a kind of mould structure, particularly a kind of novel internal diameter orthodrome hart metal product forming die structure.
Background technology
At present, original mould structure is shown in Fig. 1 and Fig. 2 tradition internal diameter orthodrome hart metal product forming die structure, it is shaping that circular arc adds the orthodrome edge of a knife 27 by straight section 26, completely can not realize product circular arc, and have 0.1 ~ 0.2mm because of orthodrome edge of a knife width 28, product endoporus has seam clearly and burr, difficulty and workload is increased to the processing of the mill of subsequent product endoporus, especially severe be because the orthodrome edge of a knife 28 width only has 0.1 ~ 0.2mm, Mould Machining difficulty is large, because pressed density is concentrated in product 25 forming process, knife-edge part is very easy to occur crackle and collapse limit, the damage of orthodrome 27 and the edge of a knife 28, corresponding increase Mold Making cost and delay product delivery cycle.
Utility model content
Technical problem to be solved in the utility model is to provide complete shaping, the novel internal diameter orthodrome hart metal product forming die structure that reduces mould loss, reduce manufacturing cost of a kind of internal diameter orthodrome product.
For solving the problems of the technologies described above, the utility model realizes as follows: design a kind of novel internal diameter orthodrome hart metal product forming die structure, it is by former, upper punch, low punch, upper core bar, lower core bar composition; Tubular former is assembled on low punch, and former endoporus and the little outer diameter face of low punch coordinate; Upper punch to be assembled in former and to be arranged on above product; Upper core bar is assembled in upper punch head bore, the small column being provided with orthodrome outside upper core bar and being slidingly fitted with lower core bar; Lower core bar is assembled in undershoot head bore, has orthodrome outside lower core bar, inside has through hole to coordinate with upper core bar; Former endoporus, upper punch lower end, upper core bar outer arc, lower core bar outer arc, the clearance space that low punch upper end is formed is formed product position.
Further, assemble when facilitating shaping, lower core bar through hole length is greater than core bar and coordinates small column length.
Further, for protecting lower core bar intensity, lower core bar through hole internal diameter is not more than 1/3 time core bar external diameter.
Good effect of the present utility model: in technical solutions of the utility model, provide a kind of novel internal diameter orthodrome hart metal product forming die structure, it improves original internal diameter orthodrome hart metal product forming die structure, reaches complete shaping orthodrome, product endoporus without straight section, impulse-free robustness; And mould is durable in use, be not easy to damage.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, not paying under the laborious prerequisite of creation, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is that the utility model is correlated with traditional moulds structural representation.
Fig. 2 is the structure for amplifying schematic diagram at traditional moulds structure chart 1 li of A place.
Fig. 3 is the structural representation of the utility model embodiment.
In figure, 11, former; 12, low punch; 13, upper punch; 14, upper core bar; 15, lower core bar; 16, product; 17, orthodrome; 21, former; 22, low punch; 23, upper punch, 24, core bar; 25, product; 26, straight section; 27, the orthodrome edge of a knife; 28, orthodrome edge of a knife width.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with detailed description of the invention and accompanying drawing, the utility model is described in further details.At this, exemplary embodiment of the present utility model and illustrating for explaining the utility model, but not as to restriction of the present utility model.
As shown in Figure 3, the utility model internal diameter orthodrome hart metal product forming die structure, it is by former 11, upper punch 13, low punch 12, upper core bar 14, and lower core bar 15 forms; Tubular former 11 is assembled on low punch 12, and former 11 endoporus and the little outer diameter face of low punch 12 coordinate; Upper punch 13 to be assembled in former 11 and to be arranged on above product; Upper core bar 14 is assembled in upper punch 13 hole, the small column being provided with orthodrome outside upper core bar 14 and being slidingly fitted with lower core bar 15; Lower core bar 15 is assembled in low punch 12 hole, has orthodrome outside lower core bar 15, inside has through hole to coordinate with upper core bar 14; Former 11 endoporus, upper punch 13 lower end, upper core bar 14 outer arc, lower core bar 15 outer arc, the clearance space that low punch 12 upper end is formed is product 16 shaping position.
Further, assemble when facilitating shaping, lower core bar 15 through hole length is greater than core bar 14 and coordinates small column length.
Further, for ensureing lower core bar 15 intensity, lower core bar 15 through hole internal diameter is not more than 1/3 time core bar external diameter.
