Methods of plastic injection mold

Cavity plate cooling by drilled holes—The cavity plate is drilled around the cavity insert and plugged with copper or aluminum taper plugs at the ends of openings. Using pipe connected at the inlet and outlet ports, water is circulated to cool the mold.

Direct cooling of core insert (baffle system)—The core is drilled by keeping sufficient wall thickness. A baffle plate is located between the drilled hole, dividing the hole into two halves, allowing the water to contact the maximum area in core so cooling may take place.

Annular cooling of cavity insert—A circular groove is made on the core for water circulation. To prevent leakage, O-rings are used above and below the cooling channel.

Core is moving side & cavity is fixed side in a mould.eg
