Description
Technical field
The utility model belongs to sintering moulds of industrial equipment technical field, and in particular to a kind of sintering chip adjustable tool mould
Tool.
Background technique
Graphite boat moulds of industrial equipment are usually used in sintering chip, generally there is two rows of tooling positions, each tooling position on graphite boat
On graphite tube is installed.When being sintered chip, in order by molybdenum sheet-aluminium foil-silicon wafer (figure is upward)-molybdenum sheet-aluminium foil-silicon
Piece-... .. is overlayed in the graphite tube on graphite boat, sturdy mutually, then graphite boat is integrally put into heating in vacuum in quartz ampoule,
Aluminium foil melts at high temperature sticks together molybdenum sheet and silicon wafer.Since the gap between molybdenum sheet, aluminium foil, silicon wafer and graphite tube is small, one
As only 0.1-0.2mm, during stacking molybdenum sheet, aluminium foil and silicon wafer be easy lower graphite powder is scratched from graphite tube to molybdenum sheet
Between silicon wafer, poor attachment is caused to become waste product；Sometimes aluminium foil fusing will lead to graphite tube rupture when flowing out from side, or will
Finished product and graphite tube (or/and graphite boat), which pour, to be sticked together, causes taking difficulty living after the completion of sintering；And graphite tube and graphite boat
Between be also easy rupture of colliding with.
Utility model content
In view of the above technical problems, the purpose of this utility model is to provide a kind of sintering chip adjustable tool mold,
The utility model generates dust pollution when can be to avoid piece installing, improve sintering effect, reduces rejection rate.
To achieve the above object, technical solution adopted in the utility model is:
A kind of sintering chip adjustable tool mold, it is characterised in that: including stainless steel boat, the stainless steel boat top is set
There are several stainless steel bases, is bolted to connection between the stainless steel base and stainless steel boat；Each stainless steel bottom
Two stainless steel columns and a stainless steel leaf spring, described two stainless steel columns and a stainless steel spring are designed on seat
Piece is triangularly arranged on stainless steel base, and the center of circle of the stainless steel base is located in the triangle.
Preferably, the stainless steel leaf spring is connect by bolt with stainless steel base；It is set on the stainless steel base
There is the bar shaped bolt hole radially arranged, the bolt matches connection with bar shaped bolt hole.
Preferably, the stainless steel leaf spring is L shape, L-shaped bottom edge is connect by bolt with stainless steel base, described
A segmental arc being bent in an arc shape upwards is equipped in the middle part of L-shaped bottom edge.
Preferably, described two stainless steel columns and a stainless steel leaf spring are arranged in stainless steel in isosceles triangle
On pedestal, wherein the line between stainless steel column and stainless steel leaf spring is waist.
Preferably, several stainless steel bases are evenly arranged in stainless steel boat in two rows.
The utility model has the following beneficial effects:
1, dust pollution is generated when the utility model can be to avoid piece installing (i.e. dress molybdenum sheet, aluminium foil, silicon wafer), improves sintering effect
Fruit reduces rejection rate.The influence for flowing aluminium when sintering is also avoided simultaneously, and prevents colliding with.
2, the utility model replaces graphite tube using two fixed stainless steel columns and an adjustable spring piece, and spatter property is more
Good, stream aluminium is unaffected, all prevents that colliding with property is more preferable using stainless steel.

Specific embodiment
The utility model in order to better understand does the technical solution of the utility model below with reference to embodiment and attached drawing
Further instruction (as shown in Fig. 1,2,3,4,5).
A kind of sintering chip adjustable tool mold, including stainless steel boat 1 (stainless steel boat 1 and graphite boat structure function
Can be identical, and it is designed with push-and-pull hooked scarf 2), 1 top of stainless steel boat is equipped with several stainless steel bases 3, the stainless steel
It is bolted to connection between pedestal 3 and stainless steel boat 1, the stainless steel base 3 is equipped with the bar shaped bolt radially arranged
Hole, the bolt match connection with bar shaped bolt hole, and the bolt can be moved along bar shaped bolt hole, are conveniently adjusted stainless steel bomb
The position of reed 5, to be suitable for the chip of different size；Two stainless steel columns 4 and one are designed on each stainless steel base 3
A stainless steel leaf spring 5, described two stainless steel columns 4 and a stainless steel leaf spring 5 are triangularly arranged at stainless steel bottom
On seat 3, the center of circle of the stainless steel base 3 is located in the triangle.The circumscribed circle of the triangle is equivalent to existing skill
Graphite tube 7 in art are not in that finished product and mold pour glutinous phenomenon when aluminium is flowed in sintering for placing molybdenum sheet, aluminium foil and silicon wafer,
And mold all uses stainless steel to make, and avoids dust.
The stainless steel leaf spring 5 is L shape, and L-shaped bottom edge is connect by bolt with stainless steel base 3, the L-shaped bottom
A segmental arc 8 being bent in an arc shape upwards is equipped in the middle part of side, it is ensured that molybdenum sheet heating deforms positioning together when expanding with heat and contract with cold.
Described two stainless steel columns 4 and a stainless steel leaf spring 5 are in that isosceles triangle is arranged in stainless steel base 3
