PURPOSE: To obtain the titled die wherein the gate section can be cut off from a resin article in the mold thereby improving the operation efficiency of the injection molding, by providing a cutting block forming a runner that connects a gate with a sprue with a cutting edge for cutting the gate.

CONSTITUTION: The gate G that is thin in thickness and long in length and the runner R connecting the gate to the sprue are formed by the cavity die body 1 and the core die body 2. The cutting block 13 is slidably attached to the core die body 2, the cutting edge 14 for cutting the gate G is attached to the cutting block 13, so that after the molding and when the resin product W is taken out from the mold, the gate can be cut off from the product.
