Introduction of permanent-electro magnetic system for quick mould clamping

permanent-electro magnetic system for quick mould clamping is using electrical impulses to open and close magnetic mould replacement system. Using the different characteristics of different magnetic materials designed to best magnetic circuit, Through the electronic control system for the distribution of internal magnetic circuit control and conversion, Make permanent magnet field in the system itself balance, The external characterization is demagnetization or relaxation state; Or released into templates work surfaces, The external characterization is magnetization or mould clamping state.

Magnetization
During the Mag phase the magnetic flux is short-circuited outside the magnetic surface safely clamping the mold with a very limited magnetic depth so as not to affect any internal part of the engaged mold.

Demagnetization
During the Demag phase the magnetic flux is short circuited inside the magnetic module frame,perfectly releasing the mold for its changeover.

A magnetic clamping mould avoids deformation and avoid the effect of internal tension.

Clamping force evenly distributed throughout the contact surface, Rather than a traditional clamping  press several points, Make mould injection molding, stamping out products maintain consistency.

DM-QMC is mainly designed against long clamping mould time, complex operation and low security of injection molding machine, punch and mould closing device. This system uses permanent-electro magnetic plate as fixed and moving plate. It can clamp or take mould through MAG/DEMAG process by simply turning safety key (removable) and push MAG/DEMAG button, accomplishing mould-changing truly in 3 minutes. It can be installed on new machine as standard equipment to sale to final customers; also can be on the traditional machine, adding 3 minutes mould change function but not changing original structure, which is practical and convenient.

The time for mold change and set up is reduced to 1/10
Rapid mold change - saving more than 90% mold changing and installation time, suitable for the current high-speed competive era, promoting an enterprise competition ability, being fast, on-time delivery, reducing production cost, saving production time.
Typical applications are as follows:
Prepare the mould in injection molding machine. After magnetization, mould adsorption on magnetic plate.
Oversize chuck
Applications on mould spotting machine
Applications on punch

International latest third generation mould exchange technology, fully surpass second raditional hydraulic clamp mould device, avoided complicated high-pressure oil and gas pipeline, without template modifying, no need worry about the blackout or pay multifarious maintenance and expensive accessories expenses.

DAMON permanent-electro magnetic system for quick mould clamping brings the enormous savings and convenience to different industries. Along with our continuous development, this system has installed hundreds of sets on different series of injection molding machine, punch, mould closing device.

Magnetic plate is made out of an entire piece of steel, and processed with special CNC, which has more compact, rigid and strong structure.
Magnetic plate uses special epoxy resin with high temperature resisting and dynamic impedance characteristics to seal the magnetic coil and magnet. The sealing height is slightly lower than the pole’s suface to avoid any possible “air-gap” caused by micro expansions.
Magnetic plate has the mounting hole on both plates and mould ejection hole on the moving plate. They’re equipped with location ring for a quick and precise mould set up.
The junction box sets inside the magneti plate to avoid damaged, with good waterproof and high impedance characteristics.
Rectangular steel plate extends to surrounding large area, which increases the contact area of magnetic plate and mould.

Induction switch

The neutral zone of the magnetic plate has inductive switch, used to detect mould contact state, in order to check the machine on normal operation and protect the operator safety.

Electronic control units

Electronic control unit design is based on the latest international standard. It has flexible interface, and is suitable for any injection molding machine and punch equipment, which is the perfect embodiment for high-tech. All control and operation function can achieve easily by remote controller. Mould stter can safely stand outside of the machines and achieve all operations.

3 levels safety device

The operation system will work only when operate 3 levels protected safety process.

Electromagnetic sensors

Electromagnetic sensors through some magnetic poles to detect saturation intensity. Only when the performances shows normal, the injetion molding machine and punch can work

Standard layout

Fixed and moving platen with center fixed ring, injection and ejection holes, is made of monoblock steel.
Electronic control unit, IP54 cabinet, interface for PLC, UCS current Control Unit, FCS Electronic Flux Control System.
Remote push-button for MAG/DEMAG process, signal lamps and interlock key.

Safety, strong
DM-QMC needs no electricity in work, but the permanent magnet suction to clamp workpiece, avoiding the danger of mould drop when magnetism loss caused by power interrupts in a sudden or drag line damage. Predictable magnetic clamping force can be above 15Kg/cm2, strong and constant, and will not weakened with the extension of time.

Practical and efficient
The use of DM-QMC is very simple and convenient. The design, no moving parts in interior, makes the chuck durable, and no need maintenance. Each control channel’s working time is no more than 0.5 second, with high efficiency of clamping and loosening. P LC interface executes microcomputer remote control, increaseing automation. And there is no heating phenomenon, no deformation.

Economic, environmental friendly
DM-QMC uses electric power just for 1-2 seconds in the magnetization and demagnetization process. In working time, it does not use any energy and can produce safe, powerful and efficient power, dispense with the outfit of electricity, liquid, gas road and accumulator in traditional machine, hydraulic, pneumatic fixture, avoid the leakage of oil and gas, fatigue damage of clamping bolts and potential safety hazard, save energy, and to be economical and environmentally friendly

Quick, convenient
DM-QMC for mould exchange or clamp mold can greatly improve the efficiency in injection molding machine and punch, which can clamp mold only in 3 minutes. Oversize mould changing time can be shortened from 2 hours to 10 minutes. Clamping force evenly distributes within 10 millimeters among the contact surface of mould and chuck, without stress deformation in the mold, better control the precision  of shuting mould, greatly improving quality consistency of injection molded parts, punch pieces, prolonging mold lifetime. For any tonnage of injection molding machine, any weight molds on punch can ensure the normal work.

Space saving, durable
Since no linking piece and other pneumatic, hydraulic components, DM-QMC saves more space, making all peripheral devices on injection molding machine, punch mould  easyier maintenance and operation. Prevent injection molding machine, punching machine parts from backplane damage. Don't need to modify threaded hole, also not need to modify the surface. The machine and the magnetic modules can retain their value for long time.

Simple operation
Operation panel instructions is clear, simple , and any non-professional workers can  master the operating essentials in 1 minute. A common moul derector, no need any special skills, can stand outside of injection molding machine and punch easily exchanging mould. Large tool change process can lowe labor costs by reducing 1-2 operators,.

Reduce investment cost
The only investment is the initial one. No cost for bolts, nuts, clamps or dedicated tools and no more maintenance of the hydraulic circuit and oil waste disposal.No loss of production. Magnetic chuck clamping force evenly distributes among all the contact surface of tools and plate, making the mold back without stress, better control the shuting mould precision, greatly reducing the loss, improving mould lifetime.

Maintenance cost almost zero
Rrapidly mould replace improves the production capacity of injection molding machine, punch. At the same time the temperature of injection molding machine maintain and the main parts of punch is maintenance, reducing waste generation . Maintenance cost is almost zero, Don't need any additional cost for screw nut, linking piece, special tools and exhaust pollution, etc.
