Abstract
PURPOSE: To obtain the titled parts for an automobile interior equipment having rich decorativeness and flexibility by a method wherein only one half body surface of a mold is made gas permeable and a nongas permeable soft foamy resin sheet is placed upon it to be sucked and closely attached and then, a foamy resin liquid is injected into the cavity.
CONSTITUTION: A mold face 3a of lower mold 2 of a pair of upper and lower molding molds 1, 2 is constituted with a gas permeable quality and upon this, a nonpermeable soft foamy resin sheet 10 (for example: a PVC sheet having a 0.8W2mm thickness, etc.) is placed. Next, a vacuum suction device 6 is operated and the sheet 10 is made to closely attached to the mold face 3a to be deformed. Next, while retaining this state, the upper mold 1 is engaged with the lower one, and a foamy resin liquid is injected into the formed cavity 9 through an injection port 8 and foam is generated to be molded and cured.
EFFECT: A tactile impression and lightness are improved and owing to a cold molding, there are no shaeriness, maldistribution of thickness and pattern oozing due to heating.
