Description

Technical Field

[0001] This invention relates to the field of metal mold casting technology, and in particular to a casting equipment and casting process for producing high-purity metal molds. Background Technology

[0002] Casting is a process in which metal is melted into a liquid that meets certain requirements and poured into a mold. After cooling and solidification, and cleaning, a casting with a predetermined shape, size, and properties is obtained. Because the cast blank is nearly formed, it can achieve the purpose of eliminating or minimizing machining, thus reducing costs and production time to a certain extent. Casting is one of the basic processes of modern equipment manufacturing industry.

[0003] Chinese invention patent application number CN202310353442.3 discloses a casting equipment for automobile hood production, relating to the field of casting equipment technology. It solves the problem that molten metal splashing not only poses a significant safety hazard to operators, but its high temperature can also easily damage multiple external devices. The casting equipment for automobile hood production includes a casting tank. A liquid-feeding mechanism is fixedly installed at the middle of the lower end of the casting tank. A liquid-receiving mechanism is installed below the liquid-feeding mechanism. A cover plate is fixedly welded to the lower end of the liquid-receiving mechanism. A casting mold is fitted around the cover plate. Connecting plates are fixedly welded to both sides of the front end of the casting mold. This invention achieves automatic flow and casting of molten aluminum alloy through the insertion between the liquid-feeding mechanism and the liquid-receiving mechanism, as well as the mutual cooperation between internal components.

[0004] The aforementioned equipment pours molten metal into the mold in one go, which can easily cause the produced parts to be missing a part.

[0067] In an optional embodiment of the present invention, in addition to the same parts as in the previous embodiment, the following steps are included:

[0068] S1, confirm the melting point of the required metal, put the metal into the melting tank 103, heat the melting tank 103 to melt the metal, and the molten metal falls into the waste bin I216 until the temperature reaches the melting point of the required metal, and maintain the temperature;

[0069] S2, the reaction vessel 212 rotates to the lower end of the melting vessel 103 under the drive of the motor, thereby receiving the molten metal;

[0070] S3, when all the molten metal is collected into the reaction vessel 212, the reaction vessel 212 rotates 90 degrees and moves to the rectangular box 311. The material tank 102 puts the deoxidizer into the reaction vessel 212 and controls the reaction vessel 212 to vibrate to expel the air in the molten metal.

[0071] S4: The discharge control plate 308 pushes the discharge rod 213 to move inside the reaction tank 212, thereby discharging a portion of the molten metal. The shaking module 306 shakes the molten metal in the module 306 evenly. Then, molten metal is added to the module 306 and shaken evenly. This process is repeated until the module 306 is filled.

[0072] S5: After module 306 is filled, reaction tank 212 rotates to the waste tank II 217 position to discharge the remaining metal in reaction tank 212 into waste tank II 217.

[0073] Working principle: When using this equipment to produce high-purity metal molds, first determine the melting point of the required metal, then put the metal into the melting tank 103. The heating tube of the melting tank 103 heats the metal and melts it. The molten metal falls into the waste bin I216 until the temperature reaches the melting point of the required metal and the temperature is maintained.

[0074] The motor of the semicircular plate 204 drives the semicircular plate 204 to rotate, which in turn drives the rectangular plate II 205 to rotate, thereby driving the connecting plate 206 to rotate, which in turn drives the reaction tank 212 to rotate, thereby moving the reaction tank 212 to the lower end of the melting tank 103 to collect the molten metal.

[0075] When all the molten metal is collected into the reaction vessel 212, the reaction vessel 212 rotates 90 degrees under the drive of the motor of the semi-circular plate 204 and moves to the upper end of the rectangular box 311. The valve inside the discharge pipe of the material tank 102 is opened, and a certain amount of deoxidizer in the material tank 102 is added into the reaction vessel 212.

[0076] During rotation, the convex shaft on one of the brackets 208 moves on the control ring 203. When the bracket 208 moves to the protrusion of the control ring 203, the protrusion of the control ring 203 drives the bracket 208 to move, which in turn drives one rack of the separation mechanism I 209 to move, which in turn drives the gear of the separation mechanism I 209 to rotate, thereby driving the other rack to move, which in turn drives the other bracket 208 to move, thereby causing the two brackets 208 to separate, thereby causing the bracket 208 to disengage from the connecting plate 206, and then allowing the connecting plate 206 to rotate at a certain angle on the rectangular plate II 205. When the reaction tank 212 rotates to the designated position, the bracket 208 is separated to the maximum extent.

[0077] Next, the motor of the vibration shaft 312 drives the vibration shaft 312 to rotate, so that the protrusion of the vibration shaft 312 contacts the rectangular plate Ⅲ210. The protrusions of the two vibration shafts 312 contact the rectangular plate Ⅲ210 in turn, which in turn causes the rectangular plate Ⅲ210 to vibrate, which in turn causes the reaction tank 212 to vibrate, which in turn causes the molten metal in the reaction tank 212 to vibrate, which causes the air in the molten metal to be discharged, and the deoxidizer floats on the top of the molten metal.

[0078] The motor drives the lead screw 302 to rotate, which in turn moves the L-shaped frame 301. When it reaches the designated position, the L-shaped frame 301 contacts the discharge control plate 308, pushing the discharge control plate 308 to move. The movement of the discharge control plate 308 pushes the discharge rod 213 to move inward toward the reaction tank 212. When it reaches the designated position, the guide groove of the discharge rod 213 contacts the molten metal, and then discharges the molten metal from the guide groove of the discharge rod 213 onto the guide plate 307. The molten metal passes through the guide... Plate 307 is fed into module 306. Then, the motor of lead screw 302 reverses and drives L-shaped frame 301 to move in the opposite direction, so that the teeth on the baffle of L-shaped frame 301 contact the rocking gear 303. Then, the teeth of L-shaped frame 301 drive the rocking gear 303 to rotate back and forth, thereby driving the mold placement plate 305 to shake, thus driving the mold placement plate 305 to shake, and shaking the molten metal in module 306 evenly. During this process, the discharge control plate 308 and connecting rod 309 return to their original positions under the action of spring.

[0079] Next, the motor of the lead screw 302 rotates in the forward direction, driving the L-shaped frame 301 to move, thereby adding molten metal to the module 306 and mixing it evenly. This process is repeated until the module 306 is filled.

[0080] After module 306 is filled, reaction tank 212 rotates 90 degrees under the drive of the motor of semi-circular plate 204. The reaction tank 212 rotates to the position of waste bin II 217. The cylinder of one of the sealing plates 211 pushes the sealing plate 211 to move, which in turn drives one rack of separation mechanism II 215 to move, which in turn drives the gear of separation mechanism II 215 to rotate, thereby driving the other rack of separation mechanism II 215 to move, which in turn drives the other sealing plate 211 to move, thereby opening the reaction tank 212 and allowing the residual metal in the reaction tank 212 to be discharged into waste bin II 217.

[0081] The cylinder recovery of the screen plate 105 drives the screen plate 105 to slide on the rectangular plate I 104, thereby moving the screen plate 105 to the designated position, and then discharging the residual metal in the melting tank 103 into the waste tank I 216.

[0082] During the rotation, the convex shaft of the bracket 208 moves to the bottom of the control ring 203, so that the two brackets 208 close under the action of the spring, and the brackets 208 contact the connecting plate 206, thereby clamping the connecting plate 206 and preventing the connecting plate 206 from shaking.

[0083] This allows air to be expelled from the molten metal, and samples can be taken from the middle layer of the molten metal for casting, resulting in higher purity metal.
