Embodiment

[0038] Reference Figures 1-8 For the second embodiment of the application, the sealing assembly 3 is arranged in the fixed plate 6 based on the previous embodiment, the sealing assembly 3 comprises two sliding rails 301 symmetrically arranged in the inside of the fixed plate 6, the two sliding rails 301 are slidably connected with two sealing blocks 302 respectively, and the two sealing blocks 302 are abutted.

[0039] Specifically, the inside of one sealing block 302 is provided with an electromagnetic plate 303, and the inside of the other sealing block 302 is provided with a magnetic block 304, the electromagnetic plate 303 is a device capable of generating a magnetic field through electric current, which is usually composed of a coil and an iron core, when electric current passes through the coil, a magnetic field will be generated around the iron core, by changing the direction or intensity of the electric current, the direction and intensity of the generated magnetic field can be controlled, at the same time, since the magnetic field of the electromagnetic plate 303 is controlled by electric current, its magnetic field intensity and direction can be adjusted to generate N or S pole current as needed. The magnetic block 304 is a permanent magnet with a fixed magnetic pole direction, generating a stable magnetic field.

[0040] The outer surfaces of the two sealing blocks 302 are fixedly connected with graphite pads 305, the graphite pads 305 are made of sealing materials, the graphite pads 305 are usually used for sealing applications in high temperature and high pressure environments, when the two sealing blocks 302 are abutted by the magnetic connection of the electromagnetic plate 303 and the magnetic block 304, the graphite pads 305 are located between them, ensuring the complete closure of the exhaust hole 201, preventing gas leakage, the sealing material refers to a material that can maintain its sealing performance and physical properties in a high temperature environment, usually with high temperature resistance, sealing, compressibility and resilience, which can be replaced by ceramic fiber and silicone rubber and the like.

[0041] Further, the two sealing blocks 302 are attracted to each other by the magnetic force of the electromagnetic plate 303 and the magnetic block 304, and are abutted together to block the exhaust hole 201, and vice versa, the current direction of the electromagnetic plate 303 is changed to generate the same magnetic force with the magnetic block 304, so that the two sealing blocks 302 are moved in opposite directions along the slide rail 301, so as to open the exhaust hole 201 and allow the gas to enter, so as to control the opening and closure of the exhaust hole 201, after the injection is completed, the two sealing blocks 302 are abutted along the slide rail 301 by the electromagnetic plate 303 and the magnetic block 304, to prevent the gas in the exhaust pipe 202 and the piston cylinder 204 from leaking.

[0042] The working principle of the present application is as follows: initial state: in use, the two sealing blocks 302 are attracted to each other by the magnetic force of the electromagnetic plate 303 and the magnetic block 304, and are abutted together to block the exhaust hole 201, while the piston cylinder 204 maintains a negative pressure state, and the injection pipe 106 is connected with the metal solution storage tank to be injected, so that the metal solution enters the injection pipe 106;

[0043] Subsequently, the control panel is operated to start the hydraulic rod 101 to push the upper mold 4 downward until it is tightly attached to the lower mold 5, when the upper mold 4 contacts the lower mold 5, the plug rod 9 will be inserted into the insertion hole 8 of the lower mold 5, ensuring that the upper mold 4 and the lower mold 5 are accurately aligned (such as Figure 5 and Figure 6As shown, molten metal solution is injected into the mold cavity through the injection pipe 106. At the same time, the current direction of the electromagnetic plate 303 is changed so that it generates the same magnetic force as the magnetic block 304, causing the two sealing blocks 302 to move in opposite directions along the slide rail 301 to open the exhaust port 201, allowing gas to enter. The electric push rod 209 is slowly started to drive the circular plate 208 and piston rod 206 to move upward. At the same time, when the circular plate 208 moves, it will drive the spring 207 to compress, so as to relieve the downward force of the electric push rod 209 and further push the piston plate 210 to rise in the piston cylinder 204. The gas generated during the injection process enters the piston cylinder 204 through the exhaust port 201 and exhaust pipe 202, reducing porosity and other defects in the casting. The heat insulation layer 205 on the outer surface of the piston cylinder 204 can enhance the heat management effect and ensure the temperature inside the piston cylinder 204 is stable.

[0044] As the piston plate 210 moves up and down, the storage ball 211 located between the piston cylinder 204 and the piston plate 210 absorbs and stores heat through the heat storage block 2111 in the inner core. It is slowly released when the temperature drops, avoiding material fatigue or deformation caused by excessive temperature changes. At the same time, the silicone sleeve 2112 can absorb moisture in the gas to prevent it from affecting the next casting. After the injection is completed, the electric push rod 209 is stopped and the electromagnetic plate 303 is activated through the control panel, so that it generates an opposite force with the magnetic block 304, causing the two sealing blocks 302 to abut against each other along the slide rail 301. The graphite pad 305 on the surface of the sealing block 302 improves its sealing performance and prevents gas leakage in the exhaust pipe 202 and piston cylinder 204.

[0045] Activate hydraulic rod 101 to separate upper mold 4 from lower mold 5 (e.g.) Figure 1 and Figure 2 As shown), the casting is separated from the lower mold 5 by the ejection mechanism so that the casting can be removed. At the same time, when the upper mold 4 moves, the exhaust pipe 202 will squeeze out the solution formed in the exhaust hole 201, separating it from the exhaust hole 201. The electromagnetic plate 303 is activated again to generate the same magnetic force as the magnetic block 304, causing the two sealing blocks 302 to separate and the waste material to fall off. After the waste material falls off, the electromagnetic plate 303 is activated immediately to make the sealing blocks 302 abut against each other and block the exhaust hole 201.

[0046] Then the hydraulic rod 101 is started to make the upper die 4 and the lower die 5 clamped, and the electromagnetic plate 303 is started to generate the same magnetic force as the magnetic block 304, so that the two sealing blocks 302 are separated, and the electric push rod 209 is started to drive the piston plate 210 to move downward through the circular plate 208 and the piston rod 206, so that the piston plate 210 makes the gas stored in the piston cylinder 204 enter between the upper die 4 and the lower die 5 through the exhaust pipe 202 and the exhaust hole 201, so as to preheat them, and when the piston plate 210 moves downward, the storage ball 211 is squeezed, so that the heat storage block 2111 in the core of the storage ball 211 releases the heat in the gas, further improving the preheating effect, and the silica gel sleeve 2112 continues to absorb the water vapor in the gas in the process, preventing the condensed water from corroding the equipment, so as to collect and store the waste heat in the gas for preheating the mold.
