のヒレ基部70上に流れ込むこととなる。In the conventional molding method as shown in FIGS. 4 to 7, the fin base portion 71 of the molding portion M is flush with the fin base portion 70 of the extrusion molding portion. Since the groove 20 for close fitting of the fin base portion 70 of the lower mold 10 has the same cross-sectional shape through the molding die, the cut line xx of the extruded portion varies and the cut base portion is formed. If the protruding dimension a of 70 varies, the connecting surface between the end surface E 1 or E 2 of the extrusion-molded portion and the die-molded portion M does not follow the set shape, or, for example, the dimension a becomes smaller than the set value. In this case, a gap is formed between the bottom surface of the groove 20 of the lower mold and the cut surface 8, and the mold molding material flows into the fin base 70 of the extrusion molding part during molding.

のヒレ基部70上に流れ込むこととなる。In the conventional molding method as shown in FIGS. 4 to 7, the fin base portion 71 of the molding portion M is flush with the fin base portion 70 of the extrusion molding portion. Since the groove 20 for close fitting of the fin base portion 70 of the lower mold 10 has the same cross-sectional shape through the molding die, the cut line xx of the extruded portion varies and the cut base portion is formed. If the protruding dimension a of 70 varies, the connecting surface between the end surface E 1 or E 2 of the extrusion-molded portion and the die-molded portion M does not follow the set shape, or, for example, the dimension a becomes smaller than the set value. In this case, a gap is formed between the bottom surface of the groove 20 of the lower mold and the cut surface 8, and the mold molding material flows into the fin base 70 of the extrusion molding part during molding.
