Application No. 08/019,335
setting said covering portion of said formed article on
one of a first and second dies which constitute a press-type
forming die with said curved portion of said covering portion
being supported by a slide core located at a forefront portion;
setting a molten resin which is a forming material of said
base portion into a gap between said first die and said second
die in a state in which said covering portion of said formed
article is being set on said first die;
clamping said press-type forming die in a state wherein
said slide core is in contact with said second die at the
forefront position and causing said molten resin to set,
thereby forming said resin, the contact between the second die
and the slide cores preventing leakage of molten resin and thus
avoiding the formation of burrs;
compressing said covering portion so as to join said
covering portion with said formed resin; and
opening said forming die and then removing the formed
article obtained in said clamping step from said press-type
forming die.
4. A method of forming a formed article having a double-
layer structure consisting of a base portion and a covering
portion which covers an outer periphery of said base portion,
said method comprising the steps of:
forming a sheet-like material, made of a thermoplastic
resin and having a surface layer and a foam layer, into a
predetermined shape by vacuum forming to obtain a preliminary
covering portion using a two-part die, one part of which is
connected to an evacuation means, said sheet-like material
being heated, said foam layer located at a corner in said two-
part die being compressed thus causing said foam layer to be
eliminated via action of said two-part die, said covering
portion being formed prior to forming said base portion;
