Abstract
A loose sintering porous die for copper comprises an inner die and an outer die which are concentrically arranged. The loose sintering porous die is characterized in that the inner die is composed of a base and a cylindrical die core arranged on the base, a boss for locating the outer die and controlling the thickness of the porous copper pipe wall, the boss and the outer die are both arranged on the base of the die core, the boss clings to the outer diameter of the die core, and the outer die clings to the outer diameter of the boss. A boss is arranged between the die core and the outer die, the boss and the outer die are respectively of a semi-circular ring structure, and the thickness of the boss equals the thickness of the porous copper pipe wall. During sintering, the dies are sintered along with copper powder at high temperature, and the dies are removed after porous copper is sintered and formed. The loose sintering porous die for the copper can bear high temperature sintering, cannot have a reaction with copper and cannot deform. The tubular porous copper with the same inner diameter and different wall thicknesses can be directly sintered and formed, it is unnecessary to add the copper powder and remove grease, and the tubular porous copper can be obtained. Furthermore, the loose sintering porous die for the copper is simple in structure, low in manufacturing cost and simple to operate. In addition, the dies are conveniently removed.
Description
Technical field
The utility model relates to a kind of sintering mould of preparing Porous Cu, is specifically related to a kind of powder metallurgy loose sintering legal system for Porous Cu mould.
Background technology
The shaping mould of metallic article has the multiple kinds of molds such as casting mold, compression molding die, metal injection molded mould, casting mold is by after metal molten, molten metal is poured into mold cavity moulding, this kind of method is applicable to casting technology field, inapplicable to preparing Porous Cu by powder metallurgic method.Compression molding die is that the metal dust that adds binding agent is packed in mold cavity, compressing, degreasing again, sintering obtains goods, and this method belongs to field of powder metallurgy, is conventional metal forming process, if but prepare the method for porous material, product porosity will be subject to the impact of press power, wants to obtain high porosity product, will be difficult to realize.Because porosity requires when high, press power must be little, and press power is too little, compacting base can not moulding or the demoulding after blank be not subject to force intensity; When press power is higher, although can moulding, porosity can reduce again.Metal injection molded mould is with metal injection molded method formed metal articles, although the method can be prepared porous material, but the organic binder bond adding in injection moulding blank is more difficult, remove, need to after multistep degreasing, sintering, could obtain final products, manufacturing cost is high, complex process.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of LOOSE POWDER SINTERING OF POROUS copper mould for the above-mentioned state of the art, can be used for the cast Porous Cu that sintering internal diameter is identical, wall thickness is different, and simple in structure, easy to operate.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of LOOSE POWDER SINTERING OF POROUS copper mould, the internal mold and the external mold that comprise concentric setting, it is characterized in that: described internal mold is comprised of base and the columniform core rod that is placed in base top, at core rod peripheral hardware, be useful on the boss of external mold location and control multi-hole copper tube wall thickness, boss and external mold are all placed on the base of core rod, boss is close to the placement of core rod external diameter, and external mold is close to the external diameter of boss and is placed.
As improvement, described base is circular, and described core rod is positioned at the center of base.
Improve, described boss and external mold form by two symmetrical semicircular ring again, and the internal diameter of boss is identical with the external diameter of core rod, and the internal diameter of external mold is identical with the external diameter of boss, and the height of external mold is identical with the height of core rod.
Compared with prior art, the utility model has the advantage of: between core rod and external mold, boss is set, boss and external mold all adopt semicircular ring structure, the thickness of boss is the thickness of Porous Cu tube wall, can adjust as required, for the cast Porous Cu that sintering internal diameter is identical, wall thickness is different, mould can pass through high temperature sintering with copper powder, the demoulding again after Porous Cu sinter molding.Mould of the present utility model can bear high temperature sintering, under high temperature, do not react with copper, indeformable, can the tubular Porous Cu of direct sintering moulding, copper powder used, without adding binding agent, without degreasing, can obtain tubular Porous Cu, and structural design is simple, low cost of manufacture, be convenient in demoulding, simple to operate.
Accompanying drawing explanation
Fig. 1 is the structural representation of mould of the present utility model;
Fig. 2 is the STRUCTURE DECOMPOSITION figure of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1, 2, the LOOSE POWDER SINTERING OF POROUS copper mould of the present embodiment, the internal mold 1, boss 3 and the external mold 2 that comprise concentric setting, internal mold 1, boss 3 and external mold 2 all adopt fusing point to form higher than the stainless steel material manufacture of 1200 ℃, can pass through high temperature sintering with copper powder, internal mold 1 is comprised of circular base 11 and the columniform core rod 12 that is placed in base 11 tops, centers, boss 3 and external mold 2 form by two symmetrical semicircular ring, boss 3 and external mold 2 are all placed on the base 11 of internal mold 1, boss 3 is close to core rod 12 external diameters and is placed, boss 3 plays positioning action, for guaranteeing the concentricity of core rod 12 and external mold 2, the thickness of boss 2 is the thickness of Porous Cu tube wall, external mold 2 is close to the external diameter of boss 3 and is placed, the internal diameter of boss 3 is identical with the external diameter of core rod 12, the internal diameter of external mold 2 is identical with the external diameter of boss 3, the height of external mold 2 is identical with the height of core rod 12.Internal mold 1, boss 3 and external mold 2 place the rear iron wire fixation of using, just can pack copper powder into, the mould that copper powder is housed is put into sintering furnace, at sintering below 1000 ℃, lower the temperature afterwards, come out of the stove, the iron wire that unclamps binding mould, due to copper powder sintering shrinkage, forms certain interval between copper powder and external mold 2, two semicircles of external mold 2 are easy to just can throw off, two semicircle gaps of light sled boss 3, boss 3 also can easily be taken off, then takes off the Porous Cu on core rod 12 with instrument.
When mould is manufactured, getting fusing point is mold materials higher than the stainless steel of 1200 ℃, makes internal mold 1, and core rod 12 outside dimensions are
