The invention provides an injection moulding die having a fixed die and a movable die, wherein the die has a melt resin filling die chamber formed by butt jointing; the fixed die comprises the following structures: a flow path supplying melt resin; a hot flow channel plate arranged in the fixed die, and the flow path allows the melt resin to flow; a plurality of nozzles respectively having a pour port used for spraying melt resins into the flow path; a plurality of pour port switch pins using axial motion to open and close the pour ports. The injection moulding die also comprises more than one driving portion freely supporting an outer end of the fixed die and driving the switch pins to axially move; the driving portions are driven by a drive source outside the fixed die, and drive the pour port switch pins so as to axially move; the injection moulding die is simplified and miniature in size, and improves work reliability of the driving portions. |
