Molding device for infusion molding of hollow part i.e. hydroelectric blade, has mold parts for defining mold cavity of hollow part, where one of mold parts comprise channel for introducing liquid resin into mold cavity

摘要

The device (10) has two mold parts (12, 14) for defining a mold cavity (16) of a hollow part. One of the mold parts comprise a channel (18) for introducing liquid resin into the mold cavity, where the channel opens into the mold cavity. Each mold part comprises complementary peripheral zones (13, 15) for surrounding the mold cavity. A supporting unit (20) has a passage for drawing vacuum from the mold parts. The peripheral zones are formed opposite to each other when the mold cavity is closed, where the supporting unit is connected to a vacuum pump. An independent claim is also included for a method for molding of a hollow part.
