Abstract
The utility model relates to a mould used in cool isostatic compression forming method in the field of powder metallurgy, comprising an outer mould and end plugs. The end plugs are arranged on both ends of the outer mould, a soft molding core is arranged in the outer mould, and an inner holes is arranged in the soft molding core. Since the soft molding core can telescopic optionally, demoulding is easy, and simultaneously, since a fluid medium is led to the inner hole of the soft molding core to transmit pressure, products are pressed under the combination of outer pressing and inner pressing. Therefore, the formed products via pressing have high precision, favorable performance and convenient control, and the size of the inner holes of the products can not change with the variation pressure. The utility model is a special mould with simple structure, easy use and favorable technology for parts having long and thin holes formed via cool isostatic compression.
Description
The utility model is a used mould in the cold isostatic pressing method the most frequently used in the field of powder metallurgy, particularly belongs to the renovation technique that isostatic cool pressing is made type elongated hole part mould therefor.
Isostatic cool pressing is made the type method and is usually used in the moulding of powder metallurgy axial workpiece, suppressing the used mould of this class part generally is to adopt rigid core for building now, the shortcoming of its existence is exactly a demoulding difficulty, easily crack and low precision, efficient low, particularly inside is provided with the structure of elongated hole (as draw ratio greater than 100), can't suppresses out with existing mold at all.
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of plastic elongated hole part is provided, and the demoulding is easy, the particular manufacturing craft of shaped article precision height, isostatic cool pressing system that performance is good.
Structural representation of the present utility model includes outer mould (1), end plug (2) as shown in drawings, and end plug (2) is arranged on the two ends of outer mould (1), is provided with flexible core (3) in the outer mould (1).
Available plastics of above-mentioned flexible core (3) or rubber or latex are made.
Describe concrete structure of the present utility model and working condition in detail below in conjunction with embodiment:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the schematic diagram of dress powder in the product compacting front mold;
Fig. 3 is the schematic diagram of product compacting;
Fig. 4 is the structural representation of shaped article.
Embodiment:
Present embodiment is to be used for suppressing the used mould of axial workpiece that is provided with elongated hole, its structural representation as shown in Figure 1, include outer mould (1), end plug (2), outer mould (1) is with infusion process or gunite, the synthetic rubber mould that methods such as moulding casting and injection moulding make, end plug (2) is arranged on the two ends of outer mould (1), be provided with flexible core (3) in the outer mould (1), flexible core (3) can be the flexible pipe made from plastics or rubber or latex that is provided with endoporus (4), the external diameter of flexible pipe is corresponding with the pore size of the set endoporus of axial workpiece, the bending that may occur when the mould dress powder for fear of flexible core (3), can in above-mentioned endoporus (4), be provided with and strengthen core (5), to guarantee the straight of moulding axis hole, strengthen the rigid core for building of core (5), and can leave the gap between the hole wall of reinforcement core (5) and endoporus (4) for making with metal material.
The utility model in use, in mould, adorn powder earlier, as shown in Figure 2, when carrying out isostatic cool pressing system, take out and allow fluid media (medium) be full of the endoporus (4) of flexible core (3) strengthening core (5), if the gap of strengthening between core (5) and the flexible core (3) can be full of fluid media (medium) and can transmit pressure, strengthen core (5) and also can not take out; Product is in the process of compacting, because pressure is etc. to be applied on the whole surface of product quietly, therefore, the each several part density of product is even; Simultaneously,, fluid media (medium) transmits pressure, the mode that adopts external pressure to combine, the straight rounding state when the set elongated endoporus of feasible compacting back product still keeps adorning powder with interior pressure owing to being introduced within the flexible core (3); In addition, because internal and external pressure balance point just in time is on the inner hole wall, flexible core (3) can outwards not swell, so the product aperture of moulding is consistent with the external diameter of used flexible core (3), can be with change in pressure, the size Control of press-formed product is very convenient.
The utility model is owing to adopted the structure of flexible core, because of flexible core can arbitrarily stretch, therefore its demoulding is very easy to, can not resemble flexible the rigid core for building, distortion, easily crack during the demoulding, also can not resemble complex process the pre-buried low-melting-point metal core, easy polluted product when heating is deviate from; In addition, owing to be provided with endoporus in the flexible core (3), fluid media (medium) can be introduced and transmit pressure in it, product is suppressed under external pressure and mode that interior pressure combines, so product precision height, the performance of compression moulding are good, the utility model is the particular manufacturing craft that a kind of isostatic cool pressing simple in structure, easy to use is made type elongated hole part.
