초록 ▼

A multi-cavity mold has flow-distribution adjusting heaters provided for respective ones of main runners branching from a common channel so as to correspond to a plurality of cavities. The amount of resin charged into the cavities is made uniform from one cavity to the next by independently controlling the heaters. Sub-runners leading respective ones of the main runners are respectively provided with heaters for adjusting gate finish. The gate finish and moldability are improved by independently controlling these heaters. The main runners hold enough resin for at least one shot, and pressure loss in the sub-runners is made equal to or greater than pressure loss in the main runners.

대표청구항 ▼

A multi-cavity mold apparatus, comprising: a plurality of sets of runners, each of said sets of runners comprising a first runner and a second runner; said first runner of each of said sets of runners having a proximal end and a distal end, a proximal end of said first runner of each of said sets of runners being attached to a supply of molten resin, said first runner being capable of holding an amount of molten resin necessary for at least one molding operation; said second runner of each of said sets of runners being attached on a first end of a corresponding said first runner at said distal end, a second end of said second runner serving as a gate facing a cavity; each of said plurality of sets of runners further comprising (i) first independently controllable temperature regulating means for flow-distribution adjustment and (ii) second independently controllable temperature regulating means for gate finish adjustment, said first independently controllable temperature regulating means being provided on said first runner of each of said sets of runners for regulating the temperature of the molten resin necessary for at least one molding operation held therein, and said second independently controllable temperature regulating means being provided on said second runner of each of said sets of runners for regulating the temperature of the molten resin in the gate portion for gate finish adjustment; wherein said first and second independently controllable temperature regulating means enable (i) a temperature of each of said plurality of sets of runners to be independently controlled and (ii) a temperature of each of said first and second runners of said plurality of sets to be independently controlled.
