What is magnetic plate for quick mold change system?

 

Quick Mold Change System is applied to injection molding machine, die casting machine, punching
machine and turning machine through magnetic plate compatible with mold changer to achieve safe, fast
and convenient replacement for large molds, to accomplish the effect of quick mold change.

 

The magnetic plate is a new type of magnetic quick mold clamping system with electric pulse opening
and closing magnetic force. The magnetic circuit is designed by using the characteristics of different
permanent magnet materials. The distribution of internal magnetic field lines is controlled by the
electronic control system. The system reaches the internal balance and then uses the magnetic force to
hold the mold.

 

The magnetic clamping system is used to fix the mold on the injection machine.Magnetic plate is
designed for the traditional injection machine and give solution for long working time on change molds, complex operation, and low security.This system uses permanent magnet sucker as fixed plate and
moving plate, just by simple actions of magnetization and demagnetization, will fix & change mold, which can indeed change mold in 3 minutes.The injection molding machine with magnetic plate is
improved mold change time to 3 minutes but without changing the original structure, it is practical and
convenient.

Honeycomb Magnetic Plate vs Standard Magnetic Plate

 

 

Comparism	Honeycomb Magnetic Plate	Standard Magnetic Plate
Rigidity & Stability	Honeycomb type with double side magnetic suction structure, the magnet of back is stronger, so the mold, magnetic plates, and the backplane of injection molding machine are combined together, which improve the rigidity of the plate, and avoid mutual vibration and offset.	Only fix the fastening screws around the plate, can not be fix screws in the middle of plate, so it can not fully guarantee the template avoid deformation when open mold.
Capacity & Versatility	Thickness 37mm, increased the opening stroke, the maximum reduction of the ejector rod and the amount of injection muzzle expansion, better control of plastic temperature	Thickness 45mm, the capacity is small, so the mold range is corresponding less than honeycomb magnetic plate.
Service life	Created in a monolithic construction: CNC machined and is completely made in a metal, with no resins, gaskets, screws, brass or other materials. It is extremely reliable: There are no components subject to wear, deformation or thermal expansion.	Surface is sealed by resin potting, with aging risk.
Quality& Efficiency	Double-sided with magnetic force, the back suction function in the stripping process to maintain the mold stability, to avoid mutual vibration and offset.	Single-sided magnetism, the magnetic force in same unit area reduced 10%-15%
Clamping force	The honeycomb structure is optimized the inside of magnetic plate, which ensure the rigidity and strength of the magnetic plate itself, as well as the magnetic force can be concentrated in a reasonable layout, so, no matter what size about the mold, the template is with more powerful clamping force	The ordinary structure clamping force is dispersed and not uniform
Personnel operation	With LCD remote controller, in use of intelligent password authorization, eliminating the need for key management inconvenience, real-time quantitative feedback status of mold and the all sensors, it is more intuitive	Mechanical control box, button control, can not quantify the real-time reaction of mold status

Advantages of Magnetic Clamping System

 

1. Easy Installation
It does not require any changes to the molds,no need to change the appearance and structures, no need punch, just fix the magnetic plate by bolts in the rear panel threaded hole or T-slot of the injection molding machine.

 

2. High Safety
The Magnetic quick mold change is controlled by Electro-permanent magnet system which is an electrical pulse activates the system in a second (Magnetization): the mold is held by the natural force of the permanent magnets. The clamping force remains constant even in the absence of a power supply, it is still keep strong and continuously magnetic force when power off and does not disappear or loss by time and temperature factors.

 

3. High Efficiency
Use Magnetic quick mold clamping system can greatly improve the mold change efficiency, drastically reduces mold changeover times (up to 90%) compared to a conventional procedure. QMCS guarantees a uniform mold clamping, that is held using the whole contact surface. Clamping the mold with uniformity allows obtaining good quality parts even with the first molds. The two mold halves are perfectly aligned: friction is minimized, preserving wear of molds and the machine. Generally the mold change and mold clamping only need 3 minutes, large mold change only needs 10 minutes.

 

4. Save Space
The thickness of Magnetic plate is about 37-50mm, space is small. The magnetic quick mold clamping system does not use platens and other pneumatic and hydraulic components,save more space and make all the peripherals of the mold in the injection molding machine are easy for maintenance and operation.

 

5. Easy Operation

Magnetic quick mold clamping system clamps molds of any shape and size with strength. A single operator easily and safely performs the operation, without working inside the machine.

 

6) Economical and Practical
Use Magnetic quick change mold system means eliminating the cost of maintenance and management of brackets, consumables, fasteners.Electricity is only used to fix and release clamping, once the mold is safely held to the correct position, will no longer need to use the electricity. Magnetic chuck application temperature can maximum up to 150°C, machine weight up from 60 tons to 5000 tons.
