Accompanying drawing explanation
Fig. 1 is that the view of just etc. surveying of the provided mould of this utility model partly cuts open schematic diagram；Fig. 2 is that this utility model structure is shown
It is intended to；Fig. 3 is with auxiliary mould mould structure sectional view；Fig. 4 is the top view of Fig. 3；1 external mold in figure, in 2
Core, 3 times plugs, 4 top plugs, 5 latches, 6 auxiliary compaction frocks, 7 strip through holes.
Detailed description of the invention
This utility model is described in further details by 1-4 below in conjunction with the accompanying drawings, but described further below be not to this reality
With novel restriction.
Mould described in present embodiment includes that external mold 1, inner core 2, lower plug 3, top plug 4 and latch 5, lower plug 3 are sleeved on external mold 1
Bottom, top plug 4 is sleeved on the top of external mold 1, is provided with inner core 2 inside external mold 1, and described external mold 1, lower plug 3 and inner core 2 pass through
Latch 5 runs through fixing, and the cavity formed between described external mold 1, inner core 2, lower plug 3 and top plug 4 is Ti-alloyed filter element forming cavity.
Being cylindrical boss bottom described inner core 2, the top of lower plug 3 is the groove suitable with described boss, and boss is inserted
Being connected in groove, external mold 1 bottom is provided with a through hole, the position that the groove of lower plug 3 is corresponding with the through hole of external mold 1 with inner core 2 boss
Being equipped with through hole, latch 5 runs through above-mentioned through hole, prevent machinery jolt ramming titanium alloy powder time inner core displacement.
The circular profile at described inner core 2 top is interior profile bottom filter element.
Described inner core 2 sidewall is provided with pattern draft 0.08 °, its object is to coring during die sinking easy；In view of cold etc. quiet
(conventional isostatic cool pressing technique is staged pressuring method, and highest pressure is less than 100MPa, pressurize to produce radial contraction during pressure
Two minutes time), pattern draft is unsuitable much, in order to avoid causing element wall thickness ununiformity even.
The diameter 54mm of described inner core 2, the internal diameter 63.6mm of external mold 1, due to produce on longitudinal direction height during isostatic cool pressing
