[0025] The top of the workbench 1 is fixedly provided with a side frame 7, which is located away from the feeding port 11 of the fixed mold 2 and the movable mold 3, and is L-shaped. The side frame 7 is fixedly provided with an electromagnet 8, which is located above the fixed mold 3 and the movable mold 2. The electromagnet 8 is fixedly connected with a cable 81, which supplies power to the electromagnet 8. The electromagnet 8 generates a strong magnetic field. Under the strong magnetic field, the fixed mold 2 and the movable mold 3 and the hand grip heat due to the magnetic thermal effect. The mold and the hand grip are preheated in sequence. The preheating can make the mold and the hand grip reach a suitable temperature when entering the molding stage, reduce the uncertainty caused by temperature fluctuation, help shorten the molding time, improve the production efficiency, and reduce the thermal stress caused by temperature difference in the molding process. Through appropriate preheating, the deformation or cracks caused by rapid cooling and heating can be reduced, the product quality and the mold life are improved.
[0026] The fixed mold 2 and the movable mold 3 are fixedly connected with a water inlet pipe 16 and a water outlet pipe 17, respectively.

One end of the electric cylinder three 19 close to the movable mold 3 is fixedly connected with a magnetic shield plate 9, which is located below the electromagnet 8 and above the movable mold 3 and the fixed mold 2.

The molten material is injected into the mold cavity 13 through the material injection port 21. After the pressure maintaining is completed, the fixed mold 2 and the movable mold 3 are water-cooled through the water inlet pipe 16 and the water outlet pipe 17. At the same time, the electromagnet 8 loses power. The electric cylinder three 19 extends the magnetic shield plate 9 made of magnetic material to shield the magnetic field.

[0027] The water inlet pipe 16 and the water outlet pipe 17 can realize efficient water cooling of the mold. The water cooling system can quickly reduce the mold temperature by efficiently taking away heat, effectively avoiding mold damage, deformation or poor molding caused by overheating. After the electromagnet 8 loses power, the magnetic field suddenly disappears, causing the magnetic working substance (such as the hand grip, the fixed mold 2 and the movable mold 3) to change from an ordered state to a disordered state, resulting in an increase in magnetic entropy. This thermal effect can help the mold and the hand grip cool down more quickly and absorb heat. The hand grip and the mold effectively dissipate heat in this process, thereby accelerating the cooling. The magnetic shield plate 9 can effectively block the influence of the magnetic field on the mold and the hand grip, preventing them from being affected by the magnetic force during demolding, thereby smoothly completing the demolding operation. Through precise temperature control design, the thermal stress caused by rapid or large temperature changes is reduced, the thermal fatigue of the mold, the hand grip and other components is reduced, thereby prolonging the service life of the equipment.
