Detailed description of the invention
Below in conjunction with specific embodiment, the utility model will be further described.
As shown in Fig. 1,2,3,4,5,6, one is colded pressing product mold, comprise die ontology 1, this die ontology 1 comprises base 2, cavity body of mould 3, described cavity body of mould about 3 two ends are opening shape structure, described cavity body of mould 3 lower end is vertically fixedly installed on base 2, upper end is plugged with a T-shaped briquetting 4, the effect of T-shaped briquetting 4 is modes that alternative rod is smash, because the words that rod is smash, its diameter is relatively little, is not easy the density distribution of powder even, causes the easy implosion of final finished product or poor quality.T-shaped briquetting 4 can connect by same forcing press, so just can avoid artificial operating.
The upper end open position of described cavity body of mould 3 sets firmly an annular die sleeve 5, described annular die sleeve 5 is hollow structure, the setting of annular die sleeve 5 mainly increases the capacity of cavity body of mould 3, and can be good at fixing, when diameter is identical, can make relatively high goods.
Based on the above, the external profile diameter of the annular die sleeve 5 of described hollow structure is equal with cavity body of mould 3 external profile diameter, the inner edge diameter of the annular die sleeve 5 of described hollow structure and cavity body of mould 3 inner edge equal diameters; Described annular die sleeve 5 be bolted mechanism between cavity body of mould 3 and be connected.By identical with external diameter with the internal diameter of cavity body of mould 3 for annular die sleeve 5 setting, make the space forming a whole smooth between the inner surface of the inner surface of cavity body of mould 3 and annular die sleeve 5 like this, there is no layering or segmentation, contribute to the shaping of powder, if the position that annular die sleeve 5 goods so made different from the internal diameter of cavity body of mould 3 dock at annular die sleeve 5 and cavity body of mould 3 will form a step, do not reach required goods.In addition, if the external diameter of annular die sleeve 5 and the different of cavity body of mould 3, overall aesthetics so after combination is had a greatly reduced quality, fixing in addition between annular die sleeve 5 and cavity body of mould 3 is also cumbersome, can only adopt between annular die sleeve 5 and cavity body of mould 3 by connector carry out serial connection fix, like this, the mold use life-span will be reduced, or the easily mold damage when punching, also aspect mechanism with bolts is not fixed relatively, because the positioning through hole 9 on locating piece 1 and the bolt hole 10 on locating piece 28 just can not be well corresponding, more to have no idea construction bolt 6, operation is very inconvenient.
Based on the above, described bolt connecting mechanism is made up of bolt 6, locating piece 1 and locating piece 28, described locating piece 1 is vertically fixedly installed on annular die sleeve 5 lateral surface, this locating piece 1 is provided with a positioning through hole 9, described locating piece 28 is vertically fixedly installed on the outward flange at cavity body of mould 3 upper end open position, this locating piece 28 is provided with a bolt hole 10 corresponding with positioning through hole 9, described bolt 6 is threaded with bolt hole 10 through after positioning through hole 9.Mechanism with bolts can very easily by annular die sleeve 5 and cavity body of mould 3 first to fixing, reduce the gap between annular die sleeve 5 and cavity body of mould 3 thus avoid powder to overflow from the gap between annular die sleeve 5 and cavity body of mould 3, but can not avoid completely, how to fix again between annular exactly die sleeve 5 and cavity body of mould 3, necessarily have some powders and enter between annular die sleeve 5 and cavity body of mould 3.
Based on the above, the described bolt connecting mechanism be made up of bolt 6, locating piece 1 and locating piece 28 is no less than three groups, and equidistant placement.In order to better increase the sealing of annular die sleeve 5 and cavity body of mould 3, at least adopt the bolt connecting mechanism that three groups such, as shown in Figure 2, have employed four groups of such bindiny mechanisms, this makes it possible to further increase sealing property between annular die sleeve 5 and cavity body of mould 3.In addition because T-shaped briquetting 4 is when work, can vibration be produced, therefore, adopt four groups of bolt connecting mechanisms can reinforce being fixedly connected with of annular die sleeve 5 and cavity body of mould 3, place due to vibrations, and loosening of producing.
Based on the above, inner edge and the outer rim at described cavity body of mould 3 upper end open position are respectively arranged with annular opening groove 1 and annular opening groove 2 32, the inner edge of described annular die sleeve 5 and outer rim are respectively arranged with annular protrusion 1 and annular protrusion 2 52, described annular protrusion 1 and annular opening groove 1 snapping, described annular protrusion 2 52 and annular opening groove 1 snapping.The use of fastening structure, most important be be place powder enter in annular die sleeve 5 and cavity body of mould 3, as shown in Figure 1, after the annular opening groove 1 of inner edge and annular protrusion 1 snapping of outer rim, as can be seen from the figure, gap between annular die sleeve 5 and cavity body of mould 3 is not the gap of a plane, but define broken line or curved gap, although the powder inside such gap can enter a bit inside gap, but can not enter a lot, shape for the entirety of goods can not have a huge impact, and also can not cause waste.The setting of annular opening 2 32 and annular protrusion 2 52 is mainly considered further to seal and prevent powder from overflowing.Inner edge and the setting of the open slot of outer rim are also to reinforce the relative fixing of annular die sleeve 5 and cavity body of mould 3 further in addition, horizontal trickle movement can not be there is, if do not arrange the open slot of inner edge and outer rim, although so there is bolt connecting mechanism to connect between them, but that is outer peripheral fixing, fixing for inward flange, then unlike fixing so good of outward flange, gap also can be larger.
Based on the above, described annular opening groove 1, annular opening groove 2 32, annular protrusion 1 and annular protrusion 2 52 cross section are square structure or arc surfaced structure, the open slot of square structure and the protruding open slot box projection being better than employing arc surfaced structure, because, as shown in Figure 4, what square aperture groove was formed is the linear gap of a right-angle folding, time inside the gap that dust enters into horizontal component, can not enter into inside the gap vertical with horizontal gap, so more difficult broken line gap of crossing this square.For the gap of arc surfaced, as shown in Figure 5, be a cambered surface gap, so powder then easily crosses the arc surfaced gap of inner edge.
Based on the above, the diameter of described T-shaped briquetting 4 is less than the internal diameter of annular die sleeve 5 and cavity body of mould 4, and what minor diameter was convenient to T-shaped briquetting 4 smashes pressure, can not be formed damage the inner surface of cavity body of mould 3.In addition, also the bottom edge of T-shaped briquetting 4 can be arranged to picture face structure, arranging of these structures can set according to the situation of reality.
