Abstract
An injection molding machine comprises a stationary platen 46 and a movable platen 40. The stationary platen 46 and movable platen 40 may be supported on a base frame 10. A mold clamping frame 56 comprises a first member 54 joined to the stationary platen 46, a second member 24 joined to the movable platen 40, and connecting members 78 and 80 for connecting the first member 54 and the second member 24 at their approximate centers. A mold clamping cylinder 50 is disposed between the first member 54 and the stationary platen 46 or between the second member 24 and the movable platen 40. The stationary platen 46 and the first member 54 are joined in a flexible manner, and the movable platen 40 and the second member 24 are similarly joined in a flexible manner.
Claims10
An injection molding machine comprising:
- a base frame;
- a stationary platen supported by the base frame;
- a movable platen slidably supported by the base frame, the movable platen being guided by the base frame to advance or retreat with respect to the stationary platen;
- a mold clamping frame joining with the stationary platen and the movable platen, the mold clamping frame comprising:
- a first member for joining with the stationary platen,
- a second member for joining with the movable platen, and
- a connecting member for connecting the first member and the second member at their approximate centers;
- a switching mechanism disposed between the second member and the movable platen;
- and
- a mold clamping cylinder unit disposed between the first member and the stationary platen,
- wherein
- the stationary platen and the movable platen are disposed between the first member and the second member,
- the mold clamping cylinder unit has a first end fixed to the stationary platen, and a first face at a second end opposite to the first end fixed to the stationary platen,
- the first member has a second face that is in contact with the first face,
- one of the first face or the second face has a curved face that protrudes towards the other of the first face or the second face,
- the second member has a third face,
- the switching mechanism has a third end fixed to the movable platen, and a fourth face at a fourth end opposite from the third end fixed to the movable platen,
- the fourth face is in contact with the third face, and
- one of the third face or the fourth face has a curved face that protrudes towards the other of the third face or the fourth face.
