Mag clamp structure and function Neodymium magnet Alnico magnet Electromagnetic coil Magnet core Super strong permanent magnet Polarity is inverted by electromagnetic coil Inverts the polarity of alnico magnet Powerfully adheres mold Effective height of magnetic flux : Approx 20 mm Lines of magnetic flux Plate thickness Clamp plate 1 Electromagnetic coil is energized for 0 . 5 sec . 1 Electromagnetic coil is energized for 0 . 5 sec 2 Polarity of alnico magnet is inverted. 2 Polarity of alnico magnet is inverted . 3 Neodymium magnet and alnico magnet become homopolar. 3 Magnetic flux of...

Displacement detec tion system（standard） Displacement or lifting of the mold can be detected by the electromagnetic coils built into the magnet core near the center of the clamp plates. When the mold moves, these electromagnetic coils detect an induction current signal. Normal clamping status Electromagnetic coil Stable magnetic flux ③ Induction current is generated. Mold is in close contact with magnet core When the mold moves Displacement detection core ② Flux changes due to displacement or lif

Air clamp, bolted type TLA Clamp or unclamp the standardized mold by one-touch operation Screw or Unscrew the mold in the limited space is not required. Air clamp, bolted type It is the clamp with safety and high reliability, which does not lose holding force because of the strong spring and special wedge mechanism even at time of zero air pressure. 9

Lever Body Micro switch At time of unclamping, the lever is retracted back in the body and it does not interfere in loading/unloading the mold. Specifications Model Holding force Clamping force Residual clamping force Full stroke Clamping stroke Safety stroke Cylinder capacity Proof pressure Operating temperature ● Residual clamping force : the clamping force when air pressure drops to zero after clamp is clamped the mold at air pressur

Mold positioning for insert / hoop molding Octagonal locate ring Mold positioning can easily be done by mating an octagonal locate block (mold side) to an octagonal locate ring (machine side) with visual observation sliding the mold on the machine table. (upper mold reference) Conventional positioning using a stopper block is no longer needed even the positioning by a parallel pin can also be improved. Also unifying the mold size is not required. Octagonal locate-ring

Platen（Mag clamp） Octagonal locate-ring Restrained 8-faces can provide easy centering. Taper allows easy mold setting Mold Octagonal locate-block High rigidity can be obtained by receiving mold weight with multiple faces.

Selection of Pre-roller each for allowable load (Mold weight) In case the mold weight is 0.5 tonf, select PRA2-0630B or PRF2-0630B. Allowable load ＊ (Mold weight) Mold travel ＊ The allowable load of above table is for 2 pre-rollers. Mold travel Allowable load Mold travel = Length from mounting surface of block to the stopper. Static load measured at the position of 1/4 of the mold travel. Select the Pre-roller where mold dimensions are within mold travel. Select Pre-roller where allowable load (kN) multiplied by the quantity is greater than the mold weight. SI conversion : Mold weight...
