Hot runner device

A hot runner device comprising:

• a fixed mold including a cavity;
• a runner block fixed to the fixed mold;
• a nozzle having a tubular shape and fixed to the fixed mold and the runner block in a manner that a tip of the nozzle faces the cavity;
• and
• a stem movable in the nozzle in an axial direction of the nozzle and configured to open and close a gate opened at the tip of the nozzle,
• the hot runner device filling the cavity with injected melted resin from the gate through the runner block, wherein
• the runner block includes:
• a first block connected to a supply port to which the melted resin is supplied, and including, on an inside thereof, a first supply flow path which communicates with the supply port and through which the melted resin flows;
• a second block connected to the first block and to the nozzle, and including, on an inside thereof, a second supply flow path through which the melted resin flows;
• a connection portion configured to connect a first end portion of the first block and a second end portion of the second block in a manner that the first end portion and the second end portion are slidable relative to each other along a second direction substantially orthogonal to a first direction that is a direction in which the stem moves, the connection portion being configured to allow the first supply flow path and the second supply flow path to communicate with each other;
• and
• a fixing mechanism provided at a position where the fixing mechanism overlaps the connection portion in the second direction, and configured to fix the connection portion, and wherein
• the second block includes, on a surface facing the fixed mold, a plurality of hole portions each engaged with a positioning member, and among the plurality of hole portions, a first hole portion which is farthest from the nozzle in the second direction is larger than a second hole portion which is closest to the nozzle in the second direction.
