Description
Technical field
The utility model belongs to technical field of mold, and in particular to a kind of cold isostatic compaction mould.
Background technique
At present during cold isostatic compaction large compact ceramic green body, due to punching block and rubber die sleeve itself
Performance deficiency, product green body water inlet phenomenon after molding is serious, and green body deformation is big, the mute of " intermediate small, both ends are big " easily occurs
Bell type structure, and billet surface is coarse, corner machining allowance increases, and manufacture difficulty increases, and eventually leads to the finished product of product green body
Rate reduces, and the production cost increases.Product green body bottom area is bigger, and green body corner arc radius after molding is bigger；Product base
Body height is lower, and green body occurs that dumbbell structure is more serious after molding, and the production difficulty and machining allowance of product are bigger, material wave
Take more serious, the process-cycle is longer, and cost is bigger.
Author has extracted massive article green body out using the method for forvacuum before forming in CN 201620024415.7 can
Most of mixing air in molding powder machine greatly reduces in forming process in the short time air compression-expansion to rubber die sleeve
The very big stress generated, reduces the quick-fried risk that rises of gum cover, and it is seriously equal existing successfully to solve the water inlet of massive article blank forming
As, but green body deformation is big, and dumbbell shape structure and big machining allowance still remain, and production difficulty is big, and yield rate is lower.Then,
On the basis of author vacuumizes before forming in CN201620024405.3, using the rubber pre-setting side of high resiliency, high-modulus
Rib matches punching block inner cavity, realizes the near-net-shape of product green body, but the study found that as gum cover forms the increasing of number
Add, due to the deformation of punching block and the aging etc. of gum cover, the dumbbell shape structure of green body is still remained after molding；Meanwhile with one
As rubber die sleeve compare, the rubber pattern of high-elastic Gao Mo set price is high, and manufacturing cost increases.For this purpose, author illustrates in this patent
It is a kind of it is new have ratio of briquetting high, gum cover water leakage ratio is low, and molding green body can keep surface regularity high for a long time, and deflection is small
Massive article green body cold isostatic compaction mould.
