The manufacturing apparatus of a resin molded product has a feed block that sets a layer configuration of the resin molded product obtained by molding a plurality of molten resins. The feed block includes a feed block body having a through hole, and a plurality of replacement blocks that are removably fitted into the through hole and have layer configuring passages corresponding to different layer configurations. A replacement block before change is pushed out of the through hole by a replacement block having a layer configuring passage corresponding to a layer configuration after change, thereby changing the layer configuration. This allows an easy change of a layer configuration, and in particular, prevents degradation of resin due to heat or oxidation, and reduces time for the change and a material loss even when a significant change of the layer configuration such as a change of a layer arrangement is performed.

What is claimed is: 1. An apparatus for manufacturing a resin molded product, comprising: a feed block which sets a layer configuration of the resin molded product obtained by molding a plurality of molten resins, wherein the feed block comprises: a feed block body having a through hole; a plurality of replacement blocks which are removably fitted into the through hole and have layer configuring passages corresponding to different layer configurations, wherein each replacement block has a length that substantially fills the through hole, a plate covering an end of the through hole and connected to a sidewall of the feed block, and a means for continuously replacing a first replacement block with a second replacement block through the through hole in a direction toward the plate. 2. The apparatus according to claim 1, wherein the feed block body and the replacement block support each other via a guide mechanism that is movable only in directions of inserting and removing the replacement block into and from the through hole. 3. The apparatus according to claim 1, wherein one of the plurality of replacement blocks has a resin configuring passage for edge lamination in which a resin different from a resin at a center is placed at both ends of the resin molded product.
