Magnetic Template for Rapid Mould Change of Injection Molding Machine

The magnetic template for rapid die change of injection moulding machine is operated by using the magnetic force of magnetic data, and it does not need electricity to adhere to the working force. Once the die is sucked in, no external factors (including human factors) can change or reduce the magnitude of the magnetic force. HVR magnetic templates include magnetic flux detection, magnetic saturation detection, dislocation detection and other detection elements, which are used to real-time detect the working status of the system and interlock with the rapid mold change control system of injection moulding machine. When opening the die, if the die is stuck or seriously expands, once the die and magnetic plate are slightly separated (usually set at 0.2mm), the machine will immediately enter a state of emergency stop (stop the opening action, and clamp the die in the machine) and alarm. Then, after manual treatment, the die can be prevented from being pulled out.

1. Wide application without adjustment

Generally, different sizes of moulds need to be installed on different tonnage machines for production. When using the magnetic template, no matter how big or thin the back plate of the die is, as long as the die component is below the upper limit of the system, it can be clamped on the magnetic template at any time without any adjustment. Whether it is horizontal, vertical or even diagonal, there is no restriction. Because the magnetic template is fully open, no clamping position is reserved for the pressure plate, so a larger die can be installed on the machine. Therefore, the use of magnetic template greatly saves the customer's investment in the machine.

2. Extension of die life and improvement of product quality

Because all the magnetic poles are placed on the surface of the magnetic template plate, especially the magnetic poles in the center of the template are also clamping points, the clamping pressure on the back plate of the die is uniform, and the stress and deformation of the die will not occur during the opening and closing process, so that the product produced by injection molding has better quality and higher consistency, and the life of the die is therefore extended. In contrast, hydraulic pressure plate only exerts force on the periphery of the back plate of the die, while the central part of the die (where the force is large when the die is opened) has no clamping force. The rigidity of the back plate is used to overcome the deformation of the die completely (but in fact there is still a large deformation), which makes the quality of the injection products not high and the consistency is not good enough to truly reflect the quality of the die. Together, the wear and tear of the die are increased. The die life is shortened.

3. High reliability without repair

The magnetic template is clamped by the magnetic force of the permanent magnet data. There are no moving parts in the disk and no working wear and tear in the machine. The power supply is used only in the instant of quick change of the mould and loading and unloading of the mould (1-3 seconds). Therefore, the lifetime of the magnetic template is very long. In addition, after one installation and commissioning, there is no need to shut down periodically in production to repair and protect it, and there are no vulnerable parts, thus greatly reducing the downtime, reducing the cost of repair and protection.

4. No operating cost, energy saving and environmental protection

There is no need for power and electricity when the injection moulding machine is switching rapidly, so there is no energy consumption and no noise. After shutdown and power failure, there is no need to unload the mould (magnetic retention), together will not cause any pollution to the products, equipment and environment, so it is a safe and energy-saving environmental protection product.
