Core material enclosing container and that core material restoration device and restoration manner null of evacuated insulation

摘要

PURPOSE: To provide an air permeable core material housing container, a core material filling device and a filling method thereof which are suitable for filling powder-like core materials uniformly and densely. ;CONSTITUTION: In order to fill powder-like core materials uniformly and densely from a core material filler hole into a core material housing container 10 where an opening part of a core material housing part is constituted by being covered with a sheet-like cover body composed of an air permeable material, the core material housing container 10 is housed in a housing space formed of a positioning guide 2 and a plate member 1. Air is exhausted from an attracting air exhaust port 7, and the core material filler hole is attracted around a nozzle 4, and air in a sealed space surrounded with a female mold 16 and a male mold 17 is exhausted from an air exhaust port 8, and when the core materials are filled from the nozzle 4 while reducing a pressure in the core material housing container 10, the core materials are filled uniformly by an exhaust air flow, and are also filled densely by discharging the contained air.;COPYRIGHT: (C)1993,JPO&Japio
