DIFFERENT PARTS OF MOULD • A mould is basically a component that contains two different assembled parts. These are punch assembly and cavity assembly. • In Injection Moulding Machine The Cavity is fixed to the fixed platen of the machine • The core is fixed to the moving platen of the machine
The material used in the mould • P-20 :-used for core and cavity • EN-36:-used for guide pin,guide bush etc • OHNS:-used for inserts, finger pin etc • MS:-used for locating ring, cam rod. • COPPER:-used for electrode
CAVITY ASSEMBLY • Locating ring provides proper alignment to the nozzle and sprue bush • Sprue bush is the channel between the nozzle and runner • This cavity plate contains runner which carries the material and gate which is restriction in the runner
Core assembly • Ejector plate assembly contains • ejector plate and ejector back plate • ejector guide pin and ejector guide bush • Inserts
MOLD INSERTS • MOLD INSERTS • The punch and cavity are actually inserts which are inserted in metal block . • This causes it to be economical and the insert can be changed when damaged . • Generally the inserts are made of hard material and the block made of cheaper material . Also hardening can be easily done of insert . • The Bolster plates are housing for these inserts.
venting • Venting is necessary because While injecting the melt, the air from the mould is required to be escape
DRAFT ANGLE• The purpose of draft is to first provide release from the core side of the mold
BOLTING• There is different size of bolts used in a mould to assemble different parts. The bolts used in most application in a mould are Allen bolts.
