Abstract
According to the present invention, a side part cavity (23) in which a side part is molded, a body part cavity (24) in which a body part is molded, and an attachment part cavity (25) in which an attachment part is molded are formed between a plurality of molding molds (21, 22), and a guiding part (26) that is configured to guide a foam to the body part cavity when an undiluted foam solution of the second synthetic resin material supplied to the side part cavity foams is arranged at a part of the side part cavity adjacent to, in a left-right direction X, a rear end part of the body part cavity in which a non-contact part is molded.
Claims16
A foam molding mold comprising:
- a plurality of molding molds for forming a foam molding body including
- a body part that is formed of a foam of a first synthetic resin material and a foam of a second synthetic resin material that is a different material from the first synthetic resin material;
- a pair of left and right side parts that are connected to both sides of the body part in a left-right direction and formed of a foam of the second synthetic resin material;
- and
- an attachment part projecting rearward integrally from the body part and the side parts,
- wherein the body part has a hip rest part that supports a hip of an occupant, and a non-contact part that connects a rear end part of the hip rest part to the attachment part,
- wherein a side part cavity in which the side part is molded, a body part cavity in which the body part is molded, and an attachment part cavity in which the attachment part is molded are formed between the plurality of molding molds, and
- wherein a guiding part that is configured to guide a foam to the body part cavity when an undiluted foam solution of the second synthetic resin material supplied to the side part cavity foams is arranged at a part of the side part cavity adjacent to, in the left-right direction, a rear end part of the body part cavity in which the non-contact part is molded.
