Injection molding device and injection unit

An injection molding device that performs injection molding of a molded article using a molding die, the injection molding device comprising:

• an injection unit that is configured to inject material into the molding die and
• a molding die opening and closing unit to which the molding die is attached and that is configured to open and close the molding die, wherein
• the injection unit includes:
• a material supply port through which the material is supplied;
• a material flow path that communicates with the material supply port and through which the material flows;
• an injection control section that includes a cylinder communicating with the material flow path and a plunger that is configured to advance and retreat in the cylinder, and that controls injection of the material;
• and
• a nozzle section that communicates with the cylinder and that injects the material,
• the material flow path includes:
• a first flow path that communicates with the cylinder;
• and
• a second flow path extending in a second direction intersecting a first direction in which the first flow path extends, and that communicates with the first flow path and the material supply port,
• the nozzle section includes:
• a nozzle;
• and
• a shut-off pin that is configured to control opening and closing of the nozzle by advancing and retreating,
• the nozzle section communicates with the cylinder such that a third direction in which the plunger extends and a fourth direction in which the shut-off pin extends intersect each other, and
• the cylinder and the nozzle section communicate with each other without any other member therebetween.
