Abstract
The utility model provides an isostatic press forming mould. The isostatic press forming mould comprises a central mould core and a mould base which is fixed with the central mould core, wherein a mould top cover is arranged at the upper end of the central mould core; a rubber sleeve is arranged outside the central mould core; an upper rubber cover and a lower rubber cover are arranged at the upper end and the lower end of the rubber sleeve respectively; and the upper rubber cover and the lower rubber cover are enwrapped on the mould top cover and the mould base respectively. The isostatic press forming mould solves the problem that the top and the bottom of an extruded product are deformed and the density distribution of the extruded product is non-uniform in the prior art, avoids phenomena such as flap edge and the like, and greatly reduces the sequent turning amount; and using performance of the product is improved.
Description
Technical field
The utility model relates to a kind of isostatic compaction mould.
Background technology
Isostatic pressing technology utilizes the Incoercibility of liquid medium and evenly transmits the characteristic of pressure, dusty material is contained in the elastic mould, adopt water, wet goods as pressure medium, dusty material is processed into the high density product of homogeneous, and the products obtained therefrom institutional framework is even, no composition segregation, the dimensional accuracy height, deformation rate is low, and therefore the stock utilization height has obtained using widely.
Use more general isostatic tooling at present generally by the rigid die SMIS, rubber mold and rigid die top cover are formed, as 96247098.8 disclosed a kind of isostatic cool pressing moulds, this mould comprises the outer mould 22 of cylindrical structure, is installed with upper end plug 11 respectively at outer mould 22 two ends, bottom end cover 44.When carrying out moulding, outer mould 22 two ends of tubular construction are sealed by the two ends end plug respectively.Generally speaking, this end plug is made for the hard rigid material, as shown in Figure 1.When suppressing, owing to can be subjected to the inhibition of rigid die base and top cover in top cover and the place's distortion of plug base chamfering, the compression ratio difference that causes the different parts powder, it is inhomogeneous that top and deformation of bottom and Density Distribution appear in the product that extrudes, and will follow phenomenons such as overlap, make later stage turning processing capacity increase, the product serviceability reduces.
The utility model content
The purpose of this utility model is to solve above-mentioned technical problem, and a kind of isostatic compaction mould is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of isostatic compaction mould, comprise the mould SMIS, also comprise the mold base that fixedly installs with the mould SMIS, described mould SMIS upper end is provided with the mould top cover, described mould SMIS also is provided with gum cover outward, described gum cover upper and lower side is respectively gluing lid and following Jiao Gai, and described gluing lid and following Jiao Gai are coated on respectively on described mould top cover and the mold base.
The beneficial effects of the utility model are mainly reflected in: the uneven problem in top and deformation of bottom and Density Distribution appears in the product that has solved extrusion of the prior art, simultaneously, removed phenomenons such as overlap, made later stage turning processing capacity reduce greatly, the product serviceability increases.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1: the static-pressure forming mould of the prior art structure schematic diagram of signing an undertaking.
Fig. 2: the improved static-pressure forming mould of the utility model structure schematic diagram of signing an undertaking.
Wherein:
11 upper end covers, 22 outer moulds, 44 bottom end covers
2 mould top covers, 3 gum covers are covered in 1 gluing
6 times Jiao Gai of 4 mould SMIS, 5 mold bases
The specific embodiment
The utility model has disclosed a kind of isostatic compaction mould, comprise mould SMIS 4, the below of mould SMIS 4 fixedly installs mold base 5, described mould SMIS 4 upper ends are respectively arranged with mould top cover 2, the described mould SMIS 4 outer gum covers 3 that also are provided with, described glue covers the lower end and is respectively gluing lid 1 and following glue lid 6, better seals in order to make Jiao Gai and gum cover, adopt gluing lid 1 and following glue lid 6 to be coated on respectively on mould top cover 2 and the mold base 5, thereby reach the effect of seal rubber sleeve together.
The uneven problem in top and deformation of bottom and Density Distribution appears in the product that the utility model has solved extrusion of the prior art, simultaneously, has removed phenomenons such as overlap, makes later stage turning processing capacity reduce greatly, and the product serviceability increases.
The utility model still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of the utility model.
