Pascal mag clamp MGA / MGB
(Magnetic clamp)
13,000kN
injection mold machine magnet clamp
Easy
die change
Instantly
clamps with strong permanent magnets (Neodymium･
Alinco Magnet)
Pascal Mag Clamp (Magnet Clamp) adheres the mold with strong magnetic force ・It is a mold clamp system for injection molding machines. Clamps instantly with the push of a button (0.5.-4.5 seconds). Energy is only required when turning On/Off (Clamp/Unclamp), no power is consumed and no heat is generated during mold clamping.
Clamp
(Magnetized)
- Electromagnetic coil is energized for 0.5 sec.
- Polarity of alnico magnet is inverted.
- Neodymium magnet and alnico magnet become homopolar.
- Magnet core securely clamps the mold.
Clamp
(Demagnetized)
- Electromagnetic coil is energized for 0.5 sec.
- Polarity of alnico magnet is inverted.
- Magnetic flux of neodymium magnet and alnico magnet is not emitted from the surface of the magnet core so that the mold can be unclamped.
Mold misalignment
detection system
Pascal’s
mag clamp can detect mold misalignment by using the electromagnetic coil built
into the magnet core near the center of the clamp plate. (When the mold moves,
the magnet coil’s generated power signals detection.)
When
the mold is misaligned → the induction current is generated.
Mold size unification not necessary
It is
not necessary to unify the mold size. (vertical, horizontal, thickness)
Even if the mold height isn’t unified, by simply adjusting the load level, horizontal loading is possible.
With a mag clamp you only need a spacer.
Maximizes the mold’s machining surface
Because the clamp does not require mounting space, it maximizes the
mold’s machining surface.
With a
hydraulic air clamp, clamp mounting space is necessary.
The core cylinder,
battery connector, coupler, hose, and other interferences can be a problem.
