This injection apparatus injects and fills the inside of a mold with a molding material, and increases the pressure. The injection apparatus is provided with a unit for a low speed step, a unit for a high speed step, a unit for a pressure increasing step, and an injection plunger. A rod of a first unit, which is any one of the three units, is mechanically coupled to the injection plunger. A rod of a second unit, which is one of the two units other than the first unit, is mechanically coupled to the first unit. A rod of a third unit, which is the unit other than the first and second units, is mechanically coupled to the second unit. |
