PURPOSE:To provide a multi-plunger type resin injection mechanism which can unify easily pressure of a plurality of plungers and is capable of making high-precision control of stepless pressure and multi-stage pressure. CONSTITUTION:In a multi-plunger type resin injeciton mechanism, a closed fluid type equalizer unit 16 transmitting driving force received from plunger driving parts 18, 19, 20, 21, 22 to a plunger 10 is arranged among a plurality of the plungers and the plunger driving parts 18, 19, 20, 21, 22. Then pressure receiving plunger pistones 30 having the same pressure receiving area, which are joined to sliding and pressing-in sides and the opposite sides within mold pots 3 of a plurality of the plungers 10 are penetrated slidably through a case of the closed fluid type equalizer unit 16, inserted into an inside closed fluid 25 and pressure is transmitted through the closed fluid 25. |
