Metallmold device for sealing by resin

PURPOSE:To raise the rate of utilization of resin by joining cavities in series and connecting one of them to a runner. CONSTITUTION:In the lower die of the metal mold, the 1st gate 16 is branched from the runner 15 which branches from a curl, and the cavity 17, the 2nd gate 16' and the cavity 17' are connected to the 1st gate. Resin flows from the curl into the cavities through the runner and the gates. By this constitution, the rate of utilization of the resin is raised and the metal mold can be miniaturized, while a processing efficiency being raised.
