  Here, a method for molding the foam molded body 1 having the above-described configuration will be described. The foam molded body 1 is a foamable resin filled in a molding space by using a molding device in which steam holes are formed in the mold facing a molding space formed by closing a mold that can be opened and closed. The particles are formed by heating with steam from the steam holes. Specifically, it has a mold that can be opened and closed, and a cylindrical steam supply means for supplying steam to a molding space formed by closing the mold, and one end of the steam supply means is By using a molding device provided facing the molding surface of the mold forming the molding space, the foamable resin particles filled in the molding space are heated by steam from one end of the steam supply means. The foamed molded body 1 is molded.

  The molding apparatus is composed of a mold configured so that a fixed mold and a movable mold can be opened and closed (contacted and separated). The fixed mold has a first molded portion formed in a convex shape or a concave shape along the opening and closing direction. The movable mold has a second molded part formed in a convex shape or a concave shape along the opening / closing direction, and is configured to move relative to the fixed mold along the opening / closing direction. One or a plurality of vents (steam supply means) in which one or a plurality of steam holes are opened at one end are provided in the wall portion of the first molding part and the second molding part.

  The vent 10 (steam supply means) of this embodiment is comprised by the cylindrical body (cylindrical body), as shown to Fig.3 (a). One end portion 10a of the cylindrical body is closed by a disc portion 10c, and the other end portion 10b is opened. A plurality of slits (long holes) 10d, which are steam holes, are formed in the disc portion 10c of the vent 10 in parallel. The slits 10d are formed as long holes, and a plurality of the slits 10d are arranged at substantially equal intervals in parallel with the short direction so that the longitudinal direction is along the radial direction of the disc portion 10c. The slit 10d is formed so that the length in the longitudinal direction becomes shorter as the slit 10d located on the outer side in the lateral direction. In addition, the separation width of the plurality of slits 10d can be set freely, each separation width is configured to be narrow, and a large number of slits are provided in the disk portion 10c, or each separation width is configured to be wide. In addition, a small number of slits can be provided in the disc portion 10c. Further, the shape of the vapor hole of the vent 10 is not limited to the plurality of slits (long holes) 10d, and may be configured by a plurality of circles (round holes) 10d as shown in FIG. As shown in FIG. 4, the vent 10 has an inner wall surface 41 of the first molding portion (or an inner wall surface 42 of the second molding portion) on the side of the molding space F formed by closing the mold. So as to protrude from the through hole 43 formed in the wall portion of the first molding portion (or the wall portion of the second molding portion). That is, one end portion 10a of the vent 10 (specifically, the outer peripheral surface and the end surface, which are the outer surfaces of the one end portion 10a) faces the molding space F, and the steam hole located on the end surface of the one end portion 10a is also molded. It faces the space F. The molding space F is a space determined by a molding surface which is an inner wall surface (including the outer surface of the one end portion 10a of the vent 10) between the first molding portion and the second molding portion when the mold is closed. is there.

  In order to obtain the foamed molded body 1 with such a molding apparatus, first, foamable synthetic resin particles are filled into a molding space formed by closing a mold. Next, steam is supplied to the steam chamber provided so as to cover the rear side of the fixed mold and the movable mold of the mold to warm the mold, and the steam is supplied into the molding space through the steam hole of the vent 10. By doing so, the foamable synthetic resin particles are heated and foam-molded. Thereafter, the mold is cooled by supplying cooling water into the steam chamber, and the mold is opened. Then, the molded foam molded body 1 is released from the mold along the opening / closing direction (that is, taken out of the mold).

  Here, when foamable synthetic resin particles are heated and foam-molded, among the foamable synthetic resin particles, those in the vicinity of the vent 10 are one end portion 10a (steam) of the vent 10 protruding toward the molding space. It has a hollow shape that conforms to the outer shape (columnar shape in this embodiment) of one end of the supply means. This hollow shape is the concave recess 2 of the foamed molded body 1. Further, when foaming synthetic resin particles are heated and foam-molded, among the foaming synthetic resin particles, those in the vicinity of the vapor hole of the one end portion 10a of the vent 10 are molded so as to be filled in the vapor hole. Is done. That is, the portion thus formed has a slit shape similar to the slit shape of the vapor hole. This slit shape is a convex trace portion 3 which is a trace due to the vapor hole (end surface of one end portion of the vapor supply means) of the vent 10. In other words, the trace portion 3 is formed on the bottom surface 21 of the concave portion 2 formed in accordance with the outer shape of the one end portion 10 a of the vent 10. Therefore, the protruding length (height) on the one end 10a side of the vent 10 with respect to the inner wall surface 41 of the first molded portion (or the inner wall surface 42 of the second molded portion) is the depth of the concave portion 2 in the direction of depression. Therefore, the length (height) is set so that the trace portion 3 which is a trace due to the vapor hole of the one end portion 10a is accommodated in the concave portion 2 in the height direction (or the depression direction of the concave portion 2).
