を与えることになる。2. Description of the Related Art Various resin foam moldings called sponges or foams have been provided and used for various purposes. The resin foam-molded body is obtained by, for example, mixing a foaming agent into a resin mixture such as polyvinyl chloride (PVC), filling the mixture in a pressure-resistant mold, and heat-molding it under a high-pressure press to form a gelled PVC. Gas is enclosed in the cell membrane to form a foam having innumerable bubbles. In the resin foam molding, the inside of the integrated structure is made to have a full-scale foam, thereby providing heat insulation,
In addition, we are trying to reduce the weight. Further, in the resin foam molding, the weight reduction and the mechanical strength are adjusted by the size of the bubbles, but their mutual relationships are contradictory.
When the weight is reduced, the mechanical strength becomes insufficient, and when trying to maintain the mechanical strength, the weight becomes heavy, and it is difficult to adjust it, and when the cross-sectional shape of the molded body becomes large, the bubbles in the outer portion and the central portion Are different in size, and are small in the outer part and large in the central part, resulting in a dense and dense state. In such a cross-sectional state, the user is given a strong sense of anxiety.

As shown in FIG. 2A, a feed material such as a resin forming the linear resin foam molded body 4 and a foaming agent is charged from a hopper 9 of the extruder 8. The feed material is melted by the heat of the heated cylinder 10 and the frictional heat of the rotating screw 11, and is transferred by the screw 11 toward the die 12. The feed material is a screw 1 in a cylinder 10.
