METHOD TO MOLD-FORM SUBSTANCE OF HEAT HARDENING SYNTHETIC MATERIAL

摘要

PURPOSE: To produce an extremely precise machine part by fitting the tip of a casting nozzle in the filling opening of an inlet piece liquidtightly and applying pressure to a synthetic material during curing. CONSTITUTION: A mixed liquid is injected into a mold 6 by a casting nozzle 14 held to temp. lower than critical temp. through the inlet piece 1 piercing the wall of the mold 6 to extend to the outside of the mold 6 and the tip of the casting nozzle 14 is fitted in the filling opening 4 of the inlet piece 1 liquidtightly. The inlet piece 1 is certainly set to temp. lower than critical temp. at least during the filling of the mold so that curing is generated so as to face to the inner wall of the mold 6, finally, to the inlet piece 1. At a time of curing in the mold 6, pressure is applied to a cured synthetic material through the casting nozzle 14.
