Abstract

PURPOSE: To easily select the position for providing a gate in the case of manufacturing the injection molding parts having an undercut part 2A.
CONSTITUTION: A fixed slide 8 is slidably supported to the inside of a mold 3 in a stationary side. A tilting extrusion slide 9 fitted with a runner 6 and a gate 7 is provided oppositely to the fixed slice 8 to the inside of a mold 4 in a movable side. Molten resin is prevented from being bitten on the slide face of the fixed slide 8 by separating the position for providing the said runner 6 by the prescribed distance apart from the slide face of the fixed slide 8.
