<p>The molding apparatus (20) of the invention includes a molding cavity (26), a flow regulating portion (27) and a degassing portion (29). The flow regulating portion (27) is situated in a die (21,22) to communicate between the molding cavity (26) and the degassing portion (29) and regulates molten material to pass through and along the flow regulating portion (27) without forming turbulent flow therein. Therefore, the molten material enters into the degassing portion (29) throughout the entire area of the degassing portion. Because of the flow regulating portion (27), the degassing portion (29) may be made large, but the molten material can be properly solidified at the degassing portion (29) without forming partial flow. Gas or air can be sufficiently removed from the die.</p> |
