を特徴とする押出成形用ダイス。(1) In an extrusion molding die that extrudes thermoplastic resin in an annular shape to form a blown film or pipe, a thickness unevenness adjustment ring is placed at a predetermined position on the inner peripheral surface of the die body upstream from the manifold section so as to surround the mandrel. The shape of the thickness unevenness adjusting ring and the position within the die body are adjusted by an adjustment bolt that is inserted from the outer circumferential side of the die body and whose tip is engaged with the thickness unevenness adjusting ring. An extrusion molding die characterized in that an inclined groove for distributing resin flow is provided on the inner circumferential surface of the thickness unevenness adjusting ring.
