Title:
MOLD FOR PRESSURE IMPREGNATION
Document Type and Number:
WIPO Patent Application WO/2014/112700
Kind Code:
A1
Abstract:
A mold for pressure impregnation according to the present invention comprises: a mold (110) of which the inside is empty so as to contain a body to be impregnated (130) and a melting impregnant (140) and having an inlet; a pressure punch interpolated into the inlet and provided to supply pressure inside of the mold (110); and a movement limiting means (160) provided inside of the mold (110) to hold the body to be impregnated (130) such that the movement of the body to be impregnated (130) can be limited. It is desirable that the movement limiting means (160) has an empty box shape such that the body to be impregnated (130) can be contained therein, and in this case, it is desirable that multiple through tubes are formed on the surfaces of the box such that the melting impregnant (140) can flow toward the body to be impregnated (130). According to the present invention, since changes in location or positioning of the body to be impregnated (130) influenced by lateral pressure and buoyancy are minimized in a process for pressure impregnating the body to be impregnated (130) with the melting impregnant (140), it is possible to enhance production yield and implement precise production of composite material.
