in the process that the spoiler 6 swings under the impact of the molten metal, the swinging plate 7 can be driven to swing at the same time, the swinging plate 7 swings to further strengthen longitudinal turbulent flow of the molten metal, the phenomenon that the molten metal is sucked and rolled outside air after being injected into a cavity is further reduced, and meanwhile, the arrangement of the balancing weight 8 can also apply a directional force to the spoiler 6, so that a balancing force is applied to the spoiler 6 when the spoiler 6 swings, and the swing amplitude is prevented from being too large; in the process that the metal liquid impacts the spoiler 6, the metal liquid contacts with the backflow elastic plate 9 firstly, the concave surface of the backflow elastic plate 9 faces upwards, so that the impact force of the metal liquid is larger, the spoiler 6 swings towards the backflow elastic plate 9 at the moment, along with the swinging of the spoiler 6, the contact area between the concave surface of the backflow elastic plate 9 and the metal liquid is changed, so that the impact force applied to the backflow elastic plate 9 is increased, after the impact force is increased to a certain degree, the backflow elastic plate 9 is bent, so that the concave surface faces downwards and the convex surface faces upwards, the metal liquid impact force applied to the backflow elastic plate 9 is reduced, the spoiler 6 rotates reversely under the action of the gravity of the counterweight block 8 at the moment, the above situation is repeated after the reverse rotation, and thus the situation that the spoiler 6 is in a balanced state due to the impact force of the water flow can be effectively prevented, and the spoiler 6 cannot swing is caused; in the swinging process of the spoiler 6, the spoiler 6 close to one side of the inner wall of the liquid injection pipe 5 can drive the knocking rod 10 to move together, the knocking rod 10 moves to drive the knocking block 11 to move, the knocking block 11 moves to knock the liquid injection pipe 5, and the vibration generated by knocking can be transmitted to the cavities inside the upper die base 1 and the movable die frame 2 so as to cause the metal liquid inside the cavities to vibrate, so that the bubbles inside the cavities are vibrated out, the sand holes of die-cast parts are further reduced, and the die-casting quality is improved; in the process of rotating the synchronizing wheel 12, the rotation of the spoilers 6 can be synchronized by arranging the synchronizing belt 13 and the driven wheel 14, so that the spoilers 6 and the spoilers 6 are prevented from colliding with each other to be worn, and the service life of the equipment is prolonged;
before the metal liquid impacts the spoiler 6, the metal liquid can firstly flow through the filter plate 16, impurities in the metal liquid can be filtered by the filter plate 16, the purity of the metal liquid is further improved, and therefore the quality of die-cast parts is improved, the spoiler 6 can simultaneously drive the backflow elastic plate 9 to impact the bottom end of the filter plate 16 in the swinging process, so that the filter plate 16 vibrates, the filtered slag can be shaken away by the vibration of the filter plate 16, the metal liquid overflow caused by blockage of the filter plate 16 is prevented, the injection flow rate of the metal liquid is further limited by the arrangement of the filter plate 16, and the metal liquid is prevented from being involved in a large amount of air due to too fast injection of workers; in the process that the follow-up wheel 14 rotates, the follow-up wheel can simultaneously drive the external rotating wheel 15 to rotate, the rotating wheel 15 rotates to drive the bouncing rod 18 to rotate, the bouncing rod 18 rotates to drive the knocking ball 19 to knock the bouncing sheet 20 in a reciprocating manner, vibration is generated, and the vibration is transmitted into the mounting frame 17 through the bouncing sheet 20 and then transmitted into the filter plate 16, so that the vibration degree of the filter plate 16 is further improved, and the filter plate 16 is prevented from being blocked;
in the process that the molten metal is injected into the cavity through the liquid injection pipe 5, the temperature of the liquid injection pipe 5 gradually rises along with the injection of the molten metal, at the moment, the temperature inside the hollow column 21 also rises synchronously, the detection plug 22 is far away according to thermal expansion and cold contraction, the detection plug 22 at the moment can be under the thrust action of gas inside the hollow column 21, so that the magnetic guide rod 23 can be driven to compress the reset spring 24 to deform and then move, the magnetic guide rod 23 moves to drive the sliding contact 25 to slide on the varistor contact 26, the resistance value of the varistor contact 26 is changed, the temperature of the molten metal injected into the cavity can be known by observing the resistance value change of the varistor contact 26, and therefore, workers can conveniently control the die-casting temperature, low-temperature pouring is realized, and the die-casting quality is improved; the heat conducting wires 27 can effectively conduct the temperature of the inner wall of the liquid injection pipe 5 into the hollow column 21, so that the accuracy of pouring temperature detection is improved; and at the in-process of magnetism guide arm 23 motion, under the effect of magnetic force, follow-up magnetic path 30 can stretch adjusting spring 31 and promote adjusting spring 31 and move after making its deformation, so in case annotate the inside high temperature of liquid pipe 5, the operation of magnetism guide arm 23 forms too big, then follow-up magnetic path 30 can drive and seal post 29 motion, make the through-hole contact with louvre 28, thereby dispel the heat to annotating the inside of liquid pipe 5, it also can accelerate the flow velocity of annotating the inside air current of liquid pipe 5 to rotate the motion that wheel 15 drove flexible pole 18 when rotating simultaneously, and then accelerate the cooling of annotating liquid pipe 5, thereby lower the temperature to the pouring of metal liquid, improve the quality of pouring, and then improve subsequent die-casting quality.
