The conventional metal solution is easy to generate hard spots formed by oxidation slag inclusion during smelting and forming when a component is formed by a die-casting forming device, and because the metal solution fills a die cavity in a high-speed injection state, gas in the die cavity is discharged in time, the metal solution is inevitably involved in the metal solution and is retained in a die casting in a gas hole form, so that the die casting has gas hole defects and the product quality is poor. The amorphous alloy has excellent physical and chemical properties different from common crystalline metal materials, high yield strength, high hardness, super elasticity, high wear resistance, high corrosion resistance and the like, and also has excellent casting performance, but has more severe forming conditions than conventional metal solutions.

The speed reducer 3212 is mounted on a mounting seat 3213 of the furnace body casing. An output shaft of the speed reducer 3212 is connected to one end of the swing bracket 3215. The other end of the swing bracket 3215 is connected to the mounting seat 3221 in the rotating mechanism 322, so that the swing of the swing bracket 3215 can drive the mounting seat 3221 to swing, thereby driving the entire rotating mechanism to swing.

The melting container is provided with a heating device for melting materials. The outer side of the mounting port of the smelting device is connected with a fixing plate 8. The mounting seat 3213 may be fixed to the fixing plate 8. A flexible tube 9 is provided between the fixed plate 8 and the mounting seat 3221, so that the rotating mechanism 32 can be swung while maintaining the vacuum degree of the vacuum chamber inside the furnace body.

It should be understood that the oscillating mechanism and the rotating mechanism may adopt any other suitable structure and manner under the condition that the above function is satisfied, for example, in the oscillating mechanism and the rotating mechanism, the speed reduction device and/or the belt wheel transmission mechanism may be eliminated by adopting a suitable motor.

When the swing motor is operated, under the control of a control system, the swing motor 3211 starts to rotate to drive the swing motor speed reducer 3212 fixed on the swing motor mounting seat to rotate, one end of the swing bracket 3215 is connected with the swing motor speed reducer, the other end of the swing bracket is connected with the mounting seat 3221, after the swing motor speed reducer starts to rotate, the swing bracket fixed with the swing motor speed reducer is driven to rotate, and the rotating force of the swing bracket acts on the connected mounting seat 3221 to cause the mounting seat 3221 to start to swing around the axis of the rotating motor. The crucible arranged at the front end of the rotating shaft can swing back and forth between the hopper connecting pipe and the material inlet of the injection charging barrel by controlling the forward and reverse rotation of the swing motor. When the smelting crucible moves to a proper position beside the hopper connecting pipe, the rotating motor starts to drive the rotating motor speed reducer to move through system control, and the belt wheel transmission device is driven to start to rotate through the movement of the rotating motor speed reducer.

In order to smoothly receive materials and protect the smelting crucible, the crucible rotates at the position beside the hopper connecting pipe, and the crucible rotates under the control of a control system to ensure that the alloy materials which slide in from the hopper connecting pipe can be just hit to the bottom of the smelting crucible. After the crucible receiving is finished, the rotating motor starts to rotate in the opposite direction to align the crucible. The swing motor starts to work, the mounting seat 3221 rotates to a proper position, the swing motor stops working, the melting crucible stops correspondingly, and the alloy material in the crucible is melted and heated through the heating device. At this time, the crucible should be located below the infrared imager and the multi-piece observation window, and the melting temperature can be monitored to judge whether the alloy material is melted or not.

After the alloy materials are melted, the swing motor continues to work, the crucible is moved to a position close to the material inlet of the injection charging barrel, the crucible is rotated under the action of the rotating motor, the molten raw materials are poured into the material inlet of the injection charging barrel, and the crucible is appropriately stopped to ensure that all the raw materials in the crucible are poured out.

And the injection charging barrel with a melt inlet is arranged inside the fixed template plate, and the amorphous melt can be added into the funnel at the melt inlet of the injection charging barrel through the rotary swinging device. After the die cavity is formed by the die-casting forming fixed die and the moving die, the melt inlet is correspondingly closer to the die cavity because the whole injection cylinder is arranged in the fixed die plate, and after the molten alloy material in the crucible is poured into the injection cylinder, because the stroke from the melt inlet to the die cavity is shorter, the injection plug in the injection cylinder can spray the molten alloy into the die cavity more quickly, so that the temperature loss of the amorphous molten alloy is less, the yield of the product is higher, and the yield can reach more than 90%. In addition, because the fuse-element entry is more close to the die cavity, the length of injection pole is shorter, and intensity is better, and equipment structure is compacter, is carrying out die-casting fashioned in-process, can guarantee that the life of injection pole is more permanent. Compared with the prior art, in the traditional horizontal vacuum die casting machine, the vacuum melting chamber is a crucible only with a rotating function, and a shaft for driving the crucible to rotate cannot swing, so that the crucible can always receive materials at a fixed position, melt and feed, and molten liquid is added into the injection charging barrel in the feeding process, so that the design of the feeding port of the injection charging barrel must be at the lower part of the melting crucible, and the feeding port is positioned at other places of the injection charging barrel and is not positioned in the die casting equipment at the position of the lower part of the melting crucible, so that the feeding work cannot be carried out, and due to the limitation of the position design of the feeding port, the design scheme cannot be better, and the equipment performance is influenced.

It is to be noted that the present swing rotation apparatus may be applied to a vacuum die casting machine configured to be horizontal, and may also be applied to a vacuum die casting machine configured to be vertical, as shown in fig. 6. In the horizontal type vacuum die casting machine, the melt in the crucible is fed to the feed opening at the injection cylinder, whereas in the vertical type vacuum die casting machine, the melt in the crucible is fed to the feed opening at the fixed die 20.
