成形装置及びその成形装置による成形方法
Document Type and Number:
Japanese Patent JP7132814
Kind Code:
B2
Abstract:
A molding apparatus for obtaining an annular molded article has a fixed die D1 and a movable die D2 capable of forming an annular cavity C. A first block B1 and a second block B2 are formed inside the cavity C in the fixed and movable dies D1 and D2. The blocks form a flow channel R communicating with the cavity C. Thus, gas generated in the cavity C and a molten metal can flow in the flow channel R. A discharge hole B2b is formed in the second block B2 to discharge the gas flowing in the flow channel R to the outside. A forming surface of the flow channel R, in the first and second blocks B1 and B2, is formed in an outer circumferential shape following an inner circumferential shape of the cavity C.
