Abstract
The utility model discloses a novel combined die for forming powder. The novel combined die comprises an ejector rod and an intermediate die, wherein a cavity in match with the ejector rod is formed in the intermediate die; the intermediate die comprises an inner die and an outer die which are tightly matched in a connection way; and a cavity in match with the ejector rod is formed in the inner die. According to the novel combined die for forming the powder, the intermediate die is provided with the structure in which the inner die is tightly matched with the outer die; and when in maintenance or replacement of the die, just the inner die is needed to be replaced, so that the cost is low.
Description
Technical field
The utility model relates to a kind of novel powder moulding assembling die.
Background technology
Need to be pressed into the powders such as raw material graphite and metal solvent after sufficiently mixing cylindricly during diamond synthesis, and need a cover particular manufacturing craft when compacting powdered graphite and catalyst.Mould therefor as shown in Figure 1 now: mainly be comprised of knock-pin fixed disk 6, knock-pin 5, middle mould 4, upperpush rod 2, upperpush rod fixed disk 1; This mold work principle is: knock-pin 5 is connected with lower oil cylinder by knock-pin fixed disk 6, upperpush rod 2 is connected with upper cylinder by upperpush rod fixed disk 1, lower oil cylinder backhaul is in position shown in Fig. 1 when putting in place, the upper cylinder backhaul is in position shown in dotted line in Fig. 1 when putting in place, pour graphite powder and catalyst powder mixture in middle mould 4 into this moment, then upperpush rod 2 presses down, after reaching system pressure, the upper cylinder backhaul, upperpush rod 2 is in position shown in dotted line in Fig. 1, then knock-pin 5 rises, outside graphite column 3 ejection dies of moulding.
This mould in use finds 1: after using a period of time, gap increase between upperpush rod 2 and middle mould 4 can cause occurring overlap, at this moment need more mold exchange, middle mould adopts Integral alloy processing, expensive: 2 often go out ready-made article graphite column 3 crackle, cause occurring a large amount of waste products, cause manpower and materials waste, cause by analysis this phenomenon former because powder internal gas in pressing process is discharged not smooth.
The utility model content
The purpose of this utility model is to provide the low novel powder moulding assembling die of a kind of repair and replacement die cost.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of novel powder moulding assembling die comprises knock-pin and middle mould, and middle mould is provided with the cavity that matches with knock-pin, and described middle mould comprises internal mold and external mold, internal mold and external mold tight fit connection, and described internal mold is provided with the cavity that matches with knock-pin.
Described internal mold adopts steel alloy, and external mold adopts common straightcarbon steel.
Described internal mold lower end is equipped with the nut that contacts with the external mold lower surface.
Described internal mold cavity upper end open place is bellmouth.
In the utility model, middle mould adopts internal mold and the friction tight structure of external mold, only gets final product with changing internal mold when needing repairing more mold exchange, and cost is low; Internal mold adopts steel alloy, and external mold adopts common straightcarbon steel, the use amount that can save steel alloy, the whole cost of reduction mould; Internal mold cavity upper end open place is bellmouth, and orifice diameter is slightly large, upperpush rod press down be conducive to powder in process in the discharge of gas, prevent that crackle from appearring in graphite column, improve product percent of pass.
Description of drawings
Fig. 1 is the existing mold structural representation;
Fig. 2 is the utility model structural representation;
Fig. 3 is A place structure enlarged drawing in Fig. 2.
The specific embodiment
As shown in Figure 2 and Figure 3, a kind of novel powder moulding assembling die, comprise the knock-pin 5 and the middle mould that are connected with knock-pin fixed disk 6, middle mould is provided with the cavity that matches with knock-pin 5, middle mould top is provided with the upperpush rod 2 that is connected with upperpush rod fixed disk 1, described middle mould comprises internal mold 42 and external mold 41, internal mold 42 and external mold 41 tight fit connections, and described internal mold 42 is provided with the cavity that matches with knock-pin 5.Internal mold 42 adopts steel alloy, and external mold 41 adopts common straightcarbon steel.Internal mold 42 lower ends are equipped with the nut 43 that contacts with external mold 41 lower surfaces, can prevent that knock-pin 5 from ejecting internal mold 42 when ejecting graphite column 3.Internal mold cavity upper end open place be bellmouth 44(as shown in Figure 3), the opening part diameter is slightly large, be conducive to powder in upperpush rod 2 presses down process in the discharge of gas, prevent that crackle from appearring in graphite column 3, improve product percent of pass.
Claims (4)
1. a novel powder moulding assembling die, comprise knock-pin and middle mould, and middle mould is provided with the cavity that matches with knock-pin, it is characterized in that, described middle mould comprises internal mold and external mold, internal mold and external mold tight fit connection, and described internal mold is provided with the cavity that matches with knock-pin.
