Abstract
PURPOSE:To provide the titled extrusion molding apparatus having a simple structure and capable to adjust a flow amount of a resin smoothly, by providing an inner mold capable to advance or retreat along a flow passage of a molten resin inside of an outer mold and shaping a flow amount adjusting part. CONSTITUTION:An apparatus by which a tubular object is extrusion molded is consisted of an outer mold 1 which is provided at a tip part of an outer mold fixing part 5, an inner mold 2 which is arranged so as to advance or retreat by an adjusting bolt 4 inside the outer mold 1, and a tubular resin flow passage 3 provided between the inner face of the outer mold 1 and the outer face of the inner mold 2. The flow amount of the resin can be readily adjusted without exerting a bad influence on a resin flow by operating the bolt 4 and making the inner mold 2 to advance or retreat according to said apparatus.
