Abstract
The utility model discloses a two -direction pressing mould, include inner cylinder mould (1), die crushion (2), go up die (3) and lower die (4), its characterized in that: place on die crushion (2) inner cylinder mould (1), and upward die (3) and lower die (4) set up respectively in the interior circle of inner cylinder mould (1) and die crushion (2). The utility model provides an one -way mould suppression inhomogeneous problem, more laborsaving energy -conservation moreover.
Description
Technical field
The utility model relates to a kind of Bidirectional pressure molding jig.
Background technology
Mould is that the shape of thing factually and structure are made in proportion, makes material become the instrument of definite shape by the method for compacting or pouring; Die-casting forming die, also known as transfer molding mould.Plastic raw materials is added the feed compartment of preheating, then apply pressure to compression leg, plastics are melting at high temperature under high pressure, and enter die cavity by the running gate system of mould, hardened forming gradually, this forming method is called die cast, and mould used is die-casting forming die.In titanium alloy synthesis field; sinter after using compacting tool set to carry out pressed sizing to powder sample; to obtain the alloy sample of definite shape; to carry out testing or other purposes; the unidirectional compacting tool set of pressed sizing mould multidigit used in prior art; it is compressed to unidirectional compacting, usually can obtain suppressing uneven sample, affects the yield of sample.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of Bidirectional pressure molding jig, press against uneven, not labour-saving problem to solve unidirectional compacting tool set.
The technical solution of the utility model is: a kind of Bidirectional pressure molding jig, and comprise inner cylinder mould, die-cushion, upper trimming die and lower punch die, inner cylinder mould is positioned on die-cushion, and upper trimming die and lower punch die are arranged in the inner circle of inner cylinder mould and die-cushion respectively.
Die-cushion is made up of two semicircles.Inner cylinder mould internal diameter and upper trimming die external diameter match, and die-cushion internal diameter is greater than lower punch die external diameter, and upper trimming die is identical with lower punch die external diameter.Lower punch die length is greater than the height of die-cushion.
The beneficial effects of the utility model: the utility model solves unidirectional mould and suppresses uneven problem, and lowering energy-saving more.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is inner cylinder mode structure schematic diagram in the utility model.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of Bidirectional pressure molding jig, comprise inner cylinder mould 1, die-cushion 2, upper trimming die 3 and lower punch die 4, inner cylinder mould 1 is positioned on die-cushion 2, and upper trimming die 3 and lower punch die 4 are arranged in the inner circle of inner cylinder mould 1 and die-cushion 2 respectively; Die-cushion 2 is made up of two semicircles; Inner cylinder mould 1 internal diameter and upper trimming die 3 external diameter match, and die-cushion 2 internal diameter is greater than lower punch die 4 external diameter, and upper trimming die 3 is identical with lower punch die 4 external diameter.Lower punch die 4 length is greater than the height of die-cushion 2.
During actual use, use the φ 16mm column type Bidirectional pressure molding jig of self-control band floating cavity die, use the interior die wall of zinc stearate powder lubrication inner cylinder mould 1, first according to assembly jig in accompanying drawing 1, add alloy raw material powder after taking off upper trimming die 3, then place upper trimming die 3, first carry out precompressed, then take off die-cushion 2, then carry out Bidirectional pressure, under 200MPa pressure, pressurize 3min is by alloy powder pre-molding.
