The vacuum die casting machine using magnetic force to transmit power of the present invention is further described with reference to the following examples:
due to the special properties of non-gold alloys, a laboratory can prepare a certain volume of bulk amorphous alloy and place a suitable amount of bulk amorphous alloy at each die casting. The vacuum die casting machine of the invention not only can reduce the waste caused by the contact of non-gold alloy and air in the die casting process, but also can reduce the abrasion of equipment and prolong the service life. When casting a mold of a type related to the non-gold alloy casting using this apparatus, the vacuum die casting machine is first connected to an existing clamping mechanism through the clamping mechanism connecting hole 13 on the right side of the mechanism.
Then, the block amorphous alloy is put into the electric heating crucible 5 through the charging door 6, because the shell 4 is a completely closed structure, the closed structure of the shell 4 replaces the sealing effect of the traditional corrugated pipe on the shell, the amorphous alloy in a molten state can be prevented from air crystallization, and the vacuum die casting of the amorphous alloy is realized, so that the vacuum pump 8 is started to vacuumize the inside of the shell 4, then the amorphous alloy in the electric heating crucible 5 is heated to obtain a molten amorphous alloy liquid, and thus, not only can a qualified non-gold alloy liquid be obtained, but also the waste of the non-gold alloy can be prevented.
And because the power source of the device is provided by the hydraulic cylinder 23, the small electromagnet 20 and the large electromagnet 21, then the hydraulic cylinder 23 is started, the hydraulic cylinder 23 pushes the hydraulic rod 1 connected with the hydraulic cylinder to move, the hydraulic rod 1 drives the hexagonal bracket 2 welded with the hydraulic rod to move, the hexagonal bracket 2 can be kept to stably run in the moving process, and the small electromagnet 20 on the hexagonal bracket 2 is driven to move by the hexagonal bracket 2.
Because magnetic force can accurate control molten metal get into the volume of mould cavity to magnetic force is connected with certain cushioning effect, can reduce the vibrations of during operation, and the size of transmission power is adjusted to change magnetic force size. Therefore, the small electromagnet 20 and the guide rail 19 are electrified, the guide rail 19 is connected with the large electromagnet 21 through the slide block 22, the guide rail 19 is electrified, so that the large electromagnet 21 is electrified, the synchronous motion with the small electromagnet 20 can be realized by utilizing the principle that like poles repel and opposite poles attract, the large electromagnet 21 connected with the injection rod 3 is driven to move through the small electromagnet 20, the slide block 22 on the large electromagnet 21 starts to slide in the guide rail 19 to drive the injection rod 3 connected with the guide rail to move, the injection rod 3 drives the injection punch 17 to perform die-casting motion, and therefore air is prevented from entering a vacuum chamber to enable the vacuum chamber to normally prepare amorphous alloy.
After the electric heating crucible 5 heats the amorphous alloy to obtain molten amorphous alloy liquid, the electric heating crucible rotates around a rotating pair connected with the supporting rod 7, the molten amorphous alloy is poured into the pressure chamber 15 through the molten metal pouring gate 18, and the molten amorphous alloy can be prevented from flowing backwards because the aperture of the injection punch 17 is equal to that of the pressure chamber 15. Next, the injection punch 17 rapidly pushes the molten amorphous alloy in the pressure chamber 15 to the inflow hole of the fixed mold 10 under the thrust of the injection rod 3, and at this time, the molten amorphous alloy is pressurized, enters the runner 24 connected thereto from the inflow hole of the fixed mold 10, and is finally conveyed to the mold cavity between the fixed mold insert 25 and the movable mold insert 26, and is rapidly cooled and solidified into a die casting. The sealing ring 9 between the movable mold 11 and the fixed mold 10, the sealing ring 9 between the fixed mold 10 and the fixed mold plate 16 and the sealing ring 9 between the movable mold 11 and the movable mold plate 12 play a role in sealing in the process of die casting of the molten amorphous alloy, and the quality of die casting is ensured.
The injection punch 17 is arranged in the pressure chamber 15 and is kept at the tail end position of the pressure chamber 15 after molten amorphous alloy is pushed, and the injection punch 17 has high speed, so that waste of metal solution caused by rapid cooling of the metal solution in the pressure chamber 15 can be prevented. When the needed die casting is finished, the die-clamping mechanism connected to the right side of the die-clamping mechanism connecting hole 13 moves to enable the movable die plate 12 to drive the movable die 11 to move, meanwhile, the movable die 11 and the fixed die 10 are separated to perform die-opening movement, the die-cast die casting is pushed out under the action of the ejection cylinder 14 connected with the movable die plate 12, and the die casting is taken out.
The moving die plate 12 drives the moving die 11 to move in the opposite direction again through the die-clamping mechanism connected with the die-clamping mechanism connecting hole 13 on the right side of the vacuum die-casting machine, the moving die is stopped after the die-clamping of the moving die 11 and the fixed die 10 is finished, the die cavity of the vacuum die-casting machine is kept in a vacuum state again, at the moment, the injection punch 17 returns, and the injection rod 3 and the large electromagnet 21 connected with the injection punch also start returning to return to the initial positions; through magnetic force, the small electromagnet 20, the hexagonal bracket 2 and the hydraulic rod 1 also start to return, and the hydraulic rod 1 returns to the inside of the hydraulic cylinder 23, so that a die-casting cycle is completed.
