Molding die, injection molding apparatus, and method for producing resin molded product

Abstract

A molding die includes a first die having a first molding surface, and a second die having a second molding surface and a runner surface connected to the second molding surface by a connection portion. In a state in which the first die and the second die are clamped, a runner is defined by the runner surface, and a cavity is defined by the first molding surface and the second molding surface. A material of at least a part of the first die and the second die contains any one of a resin, a ceramic, and glass as a main component. A relationship of T (mm)<Dm (mm) is satisfied, in which T (mm) represents a shortest distance between the connection portion and the first molding surface, and Dm (mm) represents an inner diameter of the connection portion.

Dependencies are inferred from the claim text.
