PROBLEM TO BE SOLVED: To provide a hot runner mold for injection molding which can further reduce the quantity of a residual resin in a ramification part or a corner part, where the resin tends to be easily left over, of a manifold. SOLUTION: The hot runner mold for injection molding allows an injected molten resin to be packed in a cavity through a flow path of a hot runner nozzle connected with a runner formed in the manifold. In addition, the manifold includes the ramification part which introduces the injected molten resin into the runner and the corner part which is formed in the runner and introduces the molten resin into the flow path of the hot runner nozzle connected with the runner by changing the flow direction of the molten resin introduced into the runner from the ramification part. Further, the manifold is so structured that in the ramification part and/or the corner part, or in a region on this side of the ramification part and/or the corner part, the sectional area of the flow path through which the molten resin flows, can be continuously changed.
