Claims

[Scope of utility model registration request]

A rib forming groove and a nest receiving hole communicating with one side wall of the rib forming groove are formed on the molded product main body forming wall surface of the upper mold, and a hole forming convex portion is formed in the nest receiving hole. While storing the nest, the ejector member of the molded product main body is attached to the upper mold, and the ejector member and the nest are ejected from the upper mold by an ejector drive mechanism, and the molded product body including the ribs is removed from the upper mold. The holes formed in the ribs are removed by further releasing the mold, and by protruding the ejector member more than the nest at the position where the rib is pulled out from the rib forming groove and bending the rib in the direction away from the nest. In the vertical molding apparatus for resin molded products, the ejector member is disengaged from the convex portion of the mold, and the ejector member is placed on the side opposite to the nest receiving hole of the rib forming groove of the mold. A vertical molding apparatus for a resin molded product, characterized in that the apparatus is disposed on both sides at a distance smaller than the amount of deflection displacement in the direction away from the nest of the ribs.
