Abstract
The invention relates to a mold for producing an electric device, in particular to a sintering mold for a large-size power housing. The sintering mold comprises a graphite sintering mold, an inner positioning block, an outer positioning block, an inclined surface fixing block and a steel column, wherein a cavity is formed in the graphite sintering mold; a housing, a glass insulator and a lead wire are installed in the cavity of the graphite sintering mold after being fixed by the inner positioning block and the outer positioning block; the top part of the inclined surface fixing block is an inclined surface; the inclined surface fixing block is installed on the outer side of the outer positioning block; the inclined surface faces the side wall of an inner cavity of the graphite sintering mold; and the steel column is placed on the inclined surface. According to the sintering mold for a large-size power housing provided by the invention, with the adoption of a positioning mold combined by the steel column and graphite, during sintering, only the stress caused by an expansion coefficient difference of a housing material exists in a product, so that the stress caused by inconformity of the mold expansion coefficient and the housing expansion coefficient is completely eliminated, and the sintering quality of the housing is improved; and in addition, the sintering mold is simple in machining and rapid in assembly.
Description
Technical field
The present invention relates to a kind of mould of electronic device production, be specially large scale power shell sintering mold.
Background technology
The housing of power shell generally adopts 10# Steel material, adopts graphite jig to position sintering.Because 10# steel differs comparatively large with the coefficient of expansion of graphite, easily cause the quality problems such as cracking glasses, lead-in wire are eccentric, lead-in wire is bending.The size of metal shell is larger, and lead-in wire pitch is larger, and these problems are more serious.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of positioning stablity, sinter on-deformable mould.
Concrete technical scheme is:
Large scale power shell sintering mold, comprise 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 comprise 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, under steel column Action of Gravity Field, mould breathing synchronous with shell, when eliminating cooling lead-in wire and glass because of shrink the inconsistent lead-in wire caused eccentric, be out of shape and the factor of cracking glasses; This mould versatility is better, not by the restriction of lead-in wire distribution; Good positioning effect, is specially adapted to appearance and size and the larger power shell of lead spacing.
Large scale power shell sintering mold provided by the invention, adopt the jig that steel column is combined with graphite-phase, the stress because the expansion coefficient difference of sheathing material own causes only is there is in product during sintering, completely eliminate because of mould and the inconsistent and stress brought of the shell coefficient of expansion, improve shell sintering quality, and this Mould Machining is simple, assembling is quick.

Fig. 1 is cross-sectional view of the present invention;
Fig. 2 is plan structure schematic diagram of the present invention.
Detailed description of the invention
Accompanying drawings the specific embodiment of the present invention.
As depicted in figs. 1 and 2, large scale power shell sintering mold, comprise 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 comprise 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.
To large scale, power shell that the coefficient of expansion is larger, adopt conventional graphite mould localization method, the spacing tolerance of lead-in wire can only control to ± 0.3 ~ ± 0.4mm, adopt large scale power shell sintering mold provided by the invention, lead-in wire spacing tolerance we can effectively control to ± 0.25mm within, reach the instructions for use of client.
