METHOD OF LOST PATTERN PRODUCTION WITHOUT CASTING PATTERN AND MACHINE TOOL TO MACHINE HALF-MOULD WORKING SURFACE |
摘要 |
FIELD: process engineering.SUBSTANCE: pattern of gating elements and simulator of cast pattern are placed in moulding box. Used cast pattern simulator features overall dimensions smaller than cast sizes that ensures the machining allowances. Mix is filled in moulding box and compacted. Said pattern of gating elements and simulator of cast pattern are withdrawn from half-mould. Said formed allowance for machining is removed to finish half-mould working surfaces to mount the cores and to assembly the mould.EFFECT: decreased base and labour input.29 cl, 62 dwg |
