Pressure measurement device and injection molding machine

A pressure measurement device mountable to an injection unit that injects molding material of an injection molding machine, the pressure measurement device comprising:

• a measurement cylinder mounted to the injection unit and through which the molding material injected by the injection unit flows;
• a plurality of dies mounted to the measurement cylinder and through which the molding material flows, and having different specifications;
• a flow path switching pin that selectively switches a discharge destination of the molding material to any one of the plurality of dies;
• and
• a pressure sensor that measures a pressure of the molding material in the measurement cylinder,
• wherein the measurement cylinder comprises:
• a first cylinder screwed with a nozzle mounting hole of the injection unit;
• and
• a second cylinder in which a die mounting hole to which the plurality of dies are mounted is formed on a side surface,
• wherein in a front view, an angle formed by a vertical line passing through a central axis of the second cylinder and a straight line passing through a center of the die mounting hole is 40 degrees or less.
