<p><P>PROBLEM TO BE SOLVED: To improve the strength of convex parts such as a boss, a clip stay bolt, a pawl figure, etc. in a foam molded product. <P>SOLUTION: In a state that a fixed mold 1 and a movable mold 3 are matched with each other, a molten resin is filled into a cavity 4. In this state, a movable nest 11 is set in a position retired from a mold matching surface 3a of the movable mold 3 by a predetermined distance (L1), its surface in a fixed mold 1 side functioning as a cavity surface 11a, and the molten resin is filled as far as a nest fitting portion 10. Then, only the movable mold 3 is made to move backward in a mold opening direction (in an arrow direction in the drawing) by the predetermined distance (L1) to release a pressure and foam the molten resin, whereby a foam molded product 20 is molded having a part being improved in strength. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
