[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting a cleaning mechanism, when it is necessary to remove the bubbles mixed in the molten metal, first start the three electric telescopic rods at the same time, let the three started electric telescopic rods drive the block to move through the cylindrical block, then rotate the cover plate, and then pour the molten metal into the double-hole concave block. When the molten metal contacts the straight-hole ceramic filter, the bubbles mixed in the molten metal are directly removed under the action of the straight-hole ceramic filter, and the metal slag mixed in the molten metal can be filtered down at the same time. Then the molten metal with bubbles removed will directly slide onto the inclined plate, and then flow out from the discharge pipe, and then be guided to the inside of the insulation crucible through the second electric valve and the feed pipe, which effectively solves the influence of the bubbles mixed in the molten metal on the quality of the molded castings;

At the same time, the downward moving connecting rod will also directly stretch the reset spring under the cooperation of the concave column body and the circular ring block. When the top of the static mold and the bottom of the moving mold are in contact, the air intake operation of the second air inlet pipe is directly stopped, and then the gas is transported to the inside of the concave T-shaped column through the first air inlet pipe. At this time, under the action of the internal air pressure of the concave T-shaped column, the molten metal in the heat-insulating crucible is directly diverted from the circular tube to between the static mold and the moving mold, and then the air intake operation of the first air inlet pipe is stopped. When the casting solidifies, the first electric valve is directly started to relieve the internal air pressure of the concave column body. At the same time, under the action of the reset spring, the connecting rod will drive the moving mold to reset and move, and then the solidified casting can be removed;

[0020] 3. By setting up a fixing mechanism, when it is necessary to improve the stability between the casting mechanism and the cleaning mechanism, the fixing frame is directly installed on the arc column, and then the fixing frame and the U-shaped support block are connected by the second bolt, and then the support frame is fixed to the T-shaped concave column by the third bolt, that is, the coordination of the arc column, the fixing frame and the support frame can be improved, and the stability between the casting mechanism and the cleaning mechanism can be improved, that is, the connection stability between the feed pipe, the second electric valve and the discharge pipe can be improved.

[0041] like Figure 6 and Figure 7 As shown, an air outlet pipe 114 is fixedly passed through the outer wall of the concave column body 121, a first electric valve 115 is installed at the air outlet end of the air outlet pipe 114, a connecting pipe 116 is installed at the air outlet end of the first electric valve 115, and four arc blocks 117 are fixedly arranged at equal intervals on the outer surface of the second circular plate 107.

[0042] like Figure 6 and Figure 7As shown, the four arc blocks 117 are all mounted on the outer wall of the concave column body 121 by first bolts, and an insulating crucible 118 is arranged inside the concave T-shaped column 101, through which the molten metal can be kept warm and contained.

[0043] like Figure 1 , Figure 6 , Figure 7 and Fig.10 As shown, the outer wall of the casting mechanism 1 is provided with a fixing mechanism 3, which includes an arc column 301, and the arc column 301 is fixed to the outer wall of the concave T-shaped column 101, and the front surface and the rear surface of the arc column 301 are both installed with a fixing frame 302, and the cleaning mechanism 2 and the casting mechanism 1 can be fixed together by the cooperation of the fixing frame 302, the arc column 301 and the second bolt.

The stability of the fixing frames 302 after being fixed can be increased by the support frames 303 and the third bolts.

[0045] In the present invention, when metal casting is required, the pressure-regulated casting equipment is first moved to a suitable position, and then the first air inlet pipe 102 and the second air inlet pipe 113 are connected to the two air pumps respectively, and then the three electric telescopic rods 205 are started. At this time, the three electric telescopic rods 205 started will drive the cylindrical block 220 to move upward, and the upward cylindrical block 220 will, with the cooperation of the corresponding bearings, disengage the corresponding block 221 from the top groove of the cover plate 203, and then rotate the cover plate 203. When the cover plate 203 is rotated to a vertical position, the hollow block 210 is directly used to move the bracket 208 with the straight-hole ceramic filter 209 to the inside of the double-hole concave block 201 until the bottom of the bracket 208 and the top of the two rectangular blocks 207 are Then, the molten metal solution is directly poured into the double-hole concave block 201 from the top opening. At this time, the molten metal entering the double-hole concave block 201 will directly contact the straight-hole ceramic filter 209. At this time, under the action of the straight-hole ceramic filter 209, the bubbles mixed in the molten metal are directly removed, and the metal slag that may be in the molten metal can also be filtered out. The molten metal with bubbles removed will directly flow to the inclined plate 218. At the same time, the cover plate 203 is reset, and then the electric telescopic rod 205, the cylindrical block 220 and the clamping block 221 are used to fix it. The molten metal flowing to the inclined plate 218 will directly flow to the inlet of the discharge pipe 211. At the same time, the second The electric valve 212 is closed and the first electric valve 115 is closed. The liquid entering the discharge pipe 211 will directly pass through the inside of the second electric valve 212 and the inside of the feed pipe 103, and be guided to the inside of the insulation crucible 118. When a certain amount of metal solution is reached in the insulation crucible 118, the injection of the metal melt from the opening of the double-hole concave block 201 is directly stopped, and then the second electric valve 212 is closed, and then the air pump connected to the second air inlet pipe 113 is started. At this time, the started air pump will continuously transport the generated gas from the second air inlet pipe 113 to the inside of the concave column body 121. When the gas inside the concave column body 121 continues to increase, the air pressure inside the concave column body 121 will continue to increase. At this time, the increasing air pressure will cause the connecting rod 10 8 continuously moves downward, and the downwardly moving connecting rod 108 will drive the moving mold 119 and the round rod 110 to move downward, and at the same time, the downwardly moving round rod 110 will cooperate with the concave column body 121 and the circular ring block 111 to stretch the reset spring 112. When the top of the static mold 105 contacts the bottom of the moving mold 119, the air pump directly stops the air intake operation of the second air inlet pipe 113, and then the air pump connected to the first air inlet pipe 102 is started. At this time, the started air pump will generate gas and continuously transport gas to the inside of the concave T-shaped column 101 through the first air inlet pipe 102. At this time, the gas entering the concave T-shaped column 101 will cause the air pressure inside the concave T-shaped column 101 to continuously increase. When the air pressure inside the concave T-shaped column 101 reaches a certain amount,At this time, under the action of the internal air pressure of the concave T-shaped column 101, the molten metal in the heat-insulating crucible 118 will directly extend from the inlet end to the circular tube 120 inside the molten metal, and directly guide the molten metal to the inside of the static mold 105 and the inside of the dynamic mold 119. Then, the air pump stops the air intake operation to the first air inlet pipe 102. After a certain period of time, when the casting solidifies, the first electric valve 115 is directly started, and the air pump connected to the first air inlet pipe 102 is closed. At this time, the internal air pressure of the concave column body 121 will directly enter from the air outlet pipe 114 and pass through the inner tube 120 of the concave column body 121. The air passes through the interior of the first electric valve 115 and is finally ejected from the connecting pipe 116. At the same time, the concave column body 121 that is relieving the pressure directly drives the connecting rod 108 to reset under the cooperation of the reset spring 112, the concave column body 121 and the annular block 111. The reset connecting rod 108 drives the movable mold 119 to separate from the static mold 105. At the same time, the second electric valve 212 is opened, and the air pump connected to the second air inlet pipe 113 is closed. At this time, the two hydraulic rods 217 are directly started, and the cover plate 203 is removed through the above operation steps. At this time, the moving cover plate 203 will pull the baffle plate 206 out of the rectangular hole 202, and the two hydraulic rods 217 that are activated will drive the rectangular plate 214 and the inclined plate 218 to move upward. At the same time, the upwardly moving rectangular plate 214 will drive the second heat insulation plate 215 to move. When the bottom of the inclined plate 218 moves to the top of the inlet end of the discharge pipe 211, the gas inside the concave T-shaped column 101 will directly move from the inside of the feed pipe 103, the inside of the second electric valve 212 and the inside of the discharge pipe 211 to the inside of the double-hole concave block 201, and finally dissipate from the heat dissipation hole 216. The air is released to release the internal pressure of the concave T-shaped column 101. After a period of time, the casting solidifies, and a round of metal casting is completed. At this time, the metal slag on the top of the straight hole ceramic filter 209 can also be cleaned off through the rectangular hole 202. When it is necessary to improve the stability between the casting mechanism 1 and the cleaning mechanism 2, the fixing frame 302 is directly installed on the arc column 301, and then the fixing frame 302 and the U-shaped support block 219 are connected and fixed by the second bolt, and then the support frame 303 is fixed on the top of the concave T-shaped column 101 by the third bolt.

[0046] Among them, the first electric valve 115, the second electric valve 212, the electric telescopic rod 205, the straight hole ceramic filter 209 and the hydraulic rod 217 are all existing technologies and will not be explained in detail here.

[0047] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
