Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Referring to Figures 1 - 7 , a casting device for casting production, including a base 1, a mounting frame 5 is fixedly connected to the base 1, and further includes: A vacuum tank 3, the vacuum tank 3 is installed on the base 1 and is connected to a vacuum pumping mechanism.

[0028] The vacuum pumping mechanism includes a vacuum machine 6 installed on the mounting frame 5, and a suction pipe 7 is connected between the input end of the vacuum machine 6 and the vacuum tank 3.

[0029] The vacuum machine 6 adopts the existing technology to pump the inside of the vacuum tank 3 to a vacuum, so that the casting process is carried out in a vacuum environment, effectively avoiding the influence of air on the casting process.

[0030] A mold closing mechanism, both output ends of the mold closing mechanism are hermetically penetrated and extended into the inside of the vacuum tank 3, and are correspondingly connected to an upper mold 18 and a lower mold 24, and are used to control the closing of the two molds.

[0031] The mold closing mechanism includes a hydraulic device 8 installed on the mounting frame 5. The output end of the hydraulic device 8 hermetically penetrates the top wall of the vacuum tank 3 and is fixedly connected to a fixed plate 17. The upper mold 18 is detachably installed at the bottom of the fixed plate 17. The fixed plate 26 is rotatably installed at the inner bottom of the vacuum tank 3, and the lower mold 24 is installed on the fixed plate 26. The upper mold 18 is closed with the lower mold 24 after the output end of the hydraulic device 8 extends.

[0032] The bottom of the fixed disk 17 fixes the upper die 18 through a chuck mechanism or an electromagnetic chuck mechanism in the prior art. After driving the upper die 18 to move, the fixation with the upper die 18 can be released, effectively avoiding interference of the fixed disk 17 on the subsequent casting process.

[0033] A driving motor 2 is installed inside the base 1. The output end of the driving motor 2 hermetically penetrates the bottom wall of the vacuum tank 3 and is coaxially and fixedly connected to the fixing plate 26. The fixing plate 26 is rotatably connected to the inner bottom of the vacuum tank 3.

[0034] When the driving motor 2 works, its output end rotates reciprocally, thereby driving the die to rotate reciprocally through the fixing plate 26, avoiding interference on the subsequent casting process.

[0035] Refer to Figure 4 and Figure 5 As shown in

[0036] Multiple positioning pins 25 are fixedly connected to the top of the lower die 24, and multiple positioning holes 21 are opened at the bottom of the upper die 18. The multiple positioning pins 25 are respectively and correspondingly clamped and matched with the multiple positioning holes 21.

[0037] The accuracy and stability of the mold closing of the upper die 18 and the lower die 24 are improved through the positioning pins 25 and the positioning holes 21.

[0038] The cold crucible induction melting mechanism is connected to the side of the vacuum tank 3 and is used to inject molten metal into the cavity after the two dies are closed.

[0039] The cold crucible induction melting mechanism includes a vacuum side frame 4 connected to the side of the vacuum tank 3. A side door is installed on the vacuum side frame 4, and the vacuum side frame 4 can be opened and closed through the side door. A front door is installed on the vacuum tank 3, and the vacuum tank 3 can be opened and closed through the front door.

[0040] The bottom of the vacuum side frame 4 is provided with a pushing device 14. The output end of the pushing device 14 is provided with a crucible 12. A water circulation cavity 15 is opened inside the side wall of the crucible 12. An induction coil 13 is wound around the outside of the crucible 12. The induction coil 13 is electrically connected to an external power supply. The top of the crucible 12 is communicated with a pouring outlet 16. A pouring inlet 19 is opened at the top of the upper die 18. The pouring inlet 19 is communicated with the cavity after the upper die 18 and the lower die 24 are closed.

[0041] The crucible 12 is in the shape of a plum blossom petal, reducing the shielding of the crucible 12 to the electromagnetic field and ensuring the normal melting treatment of the metal material by the cold crucible induction melting mechanism.

[0042] Water cooling mechanism. The cold crucible induction melting mechanism includes a water circulation cavity 15. The upper mold 18 is provided with an upper channel, and the lower mold 24 is provided with a lower channel. After the two molds are closed, the upper channel and the lower channel are interconnected to form a heat dissipation cavity 22. The water circulation cavity 15 and the heat dissipation cavity 22 constitute part of the water outlet pipeline of the water cooling mechanism, and the heat dissipation cavity 22 is internally connected to the vacuum chamber 3.

[0043] The water cooling mechanism includes a water inlet pipe 10. One end of the water inlet pipe 10 is connected to an external water source, and the other end hermetically penetrates the vacuum side frame 4 and is connected to the water circulation cavity 15. The end of the water circulation cavity 15 far from the water inlet pipe 10 is connected to a water outlet pipe 11. The end of the water outlet pipe 11 far from the water circulation cavity 15 is connected to the heat dissipation cavity 22. An air vent 20 is provided on the upper mold 18. One end of the air vent 20 is connected to the heat dissipation cavity 22, and the other end is connected to the inside of the vacuum chamber 3.

[0044] A three-way solenoid valve is installed between the water circulation cavity 15 and the water outlet pipe 11. The other end of the three-way solenoid valve is connected to a drain pipe. The drain pipe cools down the cooling water through a circulation device and then returns it to the external water source, improving the recycling effect of the cooling water. When the cold crucible induction melting mechanism melts the metal material, it avoids the cooling water in the water circulation cavity 15 from directly flowing into the vacuum chamber 3 through the water outlet pipe 11, reducing the working burden of the vacuum machine 6. When it is necessary to cool and shape the molten metal in the mold cavity, the three-way solenoid valve works to connect the water circulation cavity 15 and the water outlet pipe 11, and the cooling water is introduced into the heat dissipation cavity 22 to synchronously cool the two molds.

[0045] The heat dissipation cavity 22 has an annular multi-bend structure, enabling the cooling water flowing through its interior to enhance the heat dissipation effect on the inside of the two molds.

[0046] There are two cold crucible induction melting mechanisms, which are symmetrically distributed on both sides of the vacuum chamber 3.

[0047] By setting two symmetrical cold crucible induction melting mechanisms, they can work synchronously to improve the uniformity of the cooling water flowing into the heat dissipation cavity 22 through the water outlet pipe 11, enhancing the uniformity of the cooling water for mold heat dissipation. They can also work independently, alternately melting the metal material to continuously supply molten metal and improve the casting rate.

[0048] The output end of the vacuum machine 6 is connected to a condenser 9 installed on the mounting bracket 5. The water outlet end of the condenser 9 is connected to the end of the water inlet pipe 10 far from the water circulation cavity 15.

[0049] The condenser 9 uses existing technology to condense and liquefy the water vapor, condensing the evaporated water vapor back into liquid water for convenient recycling of the cooling water.

[0050] Sealing grooves are provided on the opposite sides of the upper die 18 and the lower die 24, and sealing rings 23 are fixedly connected in the sealing grooves.

[0051] The sealing rings 23 can effectively prevent water vapor from entering the cavity of the die, improving the sealing effect of the cavity.

[0052] When the present invention is in use, open the vacuum tank 3, install the lower die 24 on the fixed plate 26, install the upper die 18 on the fixed disk 17, open the vacuum side frame 4, put the metal to be melted into the crucible 12, and after the preparation work is completed, close the vacuum tank 3 and the vacuum side frame 4.

[0053] Open the vacuum machine 6 and perform a vacuum pumping process on the inside of the vacuum tank 3 through the suction pipe 7.

[0054] After keeping the inside of the vacuum tank 3 in a vacuum state, energize the induction coil 13 to perform electromagnetic induction heating on the metal in the crucible 12. As the temperature gradually rises, the metal material begins to melt in the vacuum environment. Since the oxygen content in the vacuum environment is extremely low, the metal hardly reacts with oxygen during melting, avoiding the formation of oxides and improving the purity and quality of the molten metal; at the same time, the hydrogen, oxygen and other gases dissolved in the molten metal are more likely to escape under vacuum, significantly reducing pores, pinholes and other defects, and improving the density and mechanical properties of the material.

[0055] The crucible 12 is designed in a plum blossom petal shape, which can effectively prevent the crucible from shielding the electromagnetic field and ensure the normal heating and melting of the metal.

[0056] When heating the metal material, the external water source works, and cooling water is continuously introduced into the water circulation cavity 15 on the side wall of the crucible 12 through the water inlet pipe 10. The cooling water introduced into the water circulation cavity 15 is discharged through the drain pipe. There is always cooling water passing through the water circulation cavity 15, keeping the temperature of the inner wall of the crucible 12 in a cold state. When the molten metal contacts the copper wall of the low-temperature copper crucible 12, it quickly solidifies to form a thin "freeze shell". The freeze shell serves as a physical barrier to prevent the molten metal from directly contacting the crucible 12, realizing "pollution-free by the crucible 12" melting. The plum blossom petal-shaped crucible 12 also increases the surface area of the freeze shell, improves the stability of the freeze shell, and more effectively maintains the high-temperature state inside the melt, which is beneficial to improving the energy utilization efficiency and reducing the melting cost.

[0057] When the metal melting is almost complete, first start the hydraulic device 8. The output end of the hydraulic device 8 extends to drive the fixed disk 17 to move downward, thereby driving the upper mold 18 to descend. The positioning pin 25 on the lower mold 24 is inserted into the positioning hole 21 in the upper mold 18, so that the two molds are closed, and the upper channel and the lower channel are connected to form a complete heat dissipation cavity 22. At this time, the fixed disk 17 releases the fixation of the upper mold 18, and the output end of the hydraulic device 8 contracts, driving the fixed disk 17 to move upward to avoid the interference of the fixed disk 17 on the subsequent process.

[0058] After the metal melting is completed, start the pushing device 14 to tilt the crucible 12, so that the molten metal inside it is poured into the injection port 19 of the upper mold 18 through the pouring outlet 16 and injected into the cavities of the two molds.

[0059] After the molten metal is injected in a vacuum environment, the drive motor 2 inside the base 1 works, and its output end drives the fixing plate 26 to rotate reciprocally. Since molten metal is extremely easy to react with oxygen, nitrogen and other gases at high temperatures, vacuum pumping can significantly reduce oxidation and gas inclusions, improving the chemical purity and mechanical properties of the casting; the centrifugal force generated by the reciprocating rotation can improve the fluidity of the molten metal, which is especially beneficial to filling complex structures and thin-walled parts in the cavity, while reducing porosity and shrinkage porosity defects.

[0060] The three-way solenoid valve works to connect the water circulation cavity 15 with the water outlet pipe 11. The cooling water directly enters the heat dissipation cavity 22 through the water circulation cavity 15 and the water outlet pipe 11. After the upper mold 18 and the lower mold 24 are closed, they are connected to form a complete heat dissipation cavity 22, so that the upper mold 18 and the lower mold 24 can be cooled simultaneously. Since it is in a vacuum environment inside the vacuum tank 3, the heat dissipation cavity 22 is connected to the inside of the vacuum tank 3 through the air outlet hole 20. The cooling water introduced into the heat dissipation cavity 22 will quickly vaporize into a gaseous state and rapidly expand into the vacuum tank 3. Since the vaporization of water will absorb a large amount of heat, it can quickly cool the upper mold 18 and the lower mold 24. The water vapor after vaporization is finally discharged from the air outlet hole 20 of the upper mold 18 and is quickly evacuated from the vacuum tank 3 by the exhaust pipe 7.

[0061] When the mold rotates reciprocally, the cooling water and water vapor inside the heat dissipation cavity 22 quickly diffuse into the vacuum tank 3 under the action of centrifugal force, which is convenient for improving the cooling effect of the cooling water on the mold, accelerating the rate of the water vapor being evacuated from the vacuum tank 3, and improving the casting rate.

[0062] After the water vapor is extracted by the vacuum machine 6, it is discharged into the condenser 9. After being condensed by the condenser 9, it becomes liquid water, which is convenient to flow back into the water inlet pipe 10 again for the recycling of the cooling water.

[0063] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
