Abstract
The utility model relates to a mould of electron device production usefulness specifically is jumbo size power shell sintered molded utensil, including graphite sintered molded, interior locating piece and outside fix piece, graphite sintered molded have a cavity, shell, glass insulator and lead wire by the fixed back of interior locating piece and outside fix piece, install in graphite sintered molded's cavity, still include inclined plane fixed block and steel column, inclined plane fixed block top be the inclined plane, the inclined plane fixed block install in the outside of outside fix piece, the inclined plane is towards the lateral wall of graphite sintered molded inner chamber, the steel column place on the inclined plane. The utility model provides a jumbo size power shell sintered molded utensil, the positioning die who adopts steel column and graphite to combine together only exists owing to the stress that the coefficient of expansion difference of housing material own caused in the product during sintering, has eliminated completely because of mould and the inconsistent stress that brings of shell coefficient of expansion, improves shell sintering quality to this mould processing is simple, the assembly is swift.
Description
Technical field
This utility model relates to the mould that a kind of electronic device produces, and is specially large scale power shell sintering mold.
Background technology
The housing of power shell is generally adopted 10# Steel material, adopts graphite jig to position sintering.Owing to 10# steel differs bigger with the coefficient of expansion of graphite, it is easy to cause the quality problems such as eccentric, the lead-in wire bending of cracking glasses, lead-in wire.The size of metal shell is more big, and lead-in wire pitch is more big, and these problems are more serious.
Utility model content
For above-mentioned technical problem, this utility model provides a kind of positioning stablity, sinters on-deformable mould.
Concrete technical scheme is:
Large scale power shell sintering mold, including graphite sintering mould, inner position block and outside fix block, described graphite sintering mould has cavity, and shell, glass insulator and lead-in wire are arranged in the cavity of graphite sintering mould after being fixed by described inner position block and outside fix block；Also including inclined-plane fixed block and steel column, described fixed block top, inclined-plane is inclined-plane；Described inclined-plane fixed block is arranged on the outside of outside fix block, and inclined-plane is towards the sidewall of graphite sintering mold cavity, and described steel column is placed on inclined-plane.
Steel column is identical with sheathing material, and under steel column action of gravity, mould breathing Tong Bu with shell, when eliminating cooling, lead-in wire and glass are because shrinking the factor of inconsistent lead-in wire bias, deformation and the cracking glasses caused；This mould versatility is better, not by the restriction of lead-in wire distribution；Good positioning effect, is particularly well-suited to overall dimensions and the relatively larger power shell of lead spacing.
The large scale power shell sintering mold that this utility model provides, adopt the jig that steel column is combined with graphite-phase, product only exists during sintering the stress owing to the expansion coefficient difference of sheathing material own causes, completely eliminate the stress brought because mould and the shell coefficient of expansion are inconsistent, improve shell sintering quality, and the processing of this mould is simple, assembling is quick.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model；
Fig. 2 is plan structure schematic diagram of the present utility model.
Detailed description of the invention
Accompanying drawings detailed description of the invention of the present utility model.
As depicted in figs. 1 and 2, large scale power shell sintering mold, including graphite sintering mould 1, inner position block 2 and outside fix block 3, described graphite sintering mould 1 has cavity, shell, glass insulator and lead-in wire are arranged in the cavity of graphite sintering mould 1 after being fixed by described inner position block 2 and outside fix block 3；Also including inclined-plane fixed block 4 and steel column 5, described inclined-plane fixed block 4 top is inclined-plane；Described inclined-plane fixed block 4 is arranged on the outside of outside fix block 3, and inclined-plane is towards the sidewall of graphite sintering mould 1 inner chamber, and described steel column 5 is placed on inclined-plane.
The power shell that large scale, the coefficient of expansion is relatively larger, adopt conventional graphite mould localization method, the spacing tolerance of lead-in wire can only control to ± 0.3～± 0.4mm, adopt the large scale power shell sintering mold that this utility model provides, the spacing tolerance of lead-in wire we can effectively control within ± 0.25mm, reached the instructions for use of client.
