Description

Technical Field

[0001] The invention relates to the field of metal casting equipment, in particular to a light alloy motor housing casting mould. Background Art

[0002] Light alloy motor housing casting molds are mainly used in the production process of light alloy motor housings to cast and shape light alloy motor housing parts. The mold is a tool used to manufacture products. It can pour molten metal materials into the mold by carving or compressing. After cooling and solidification, a casting with a specific shape and size can be obtained. In the production process of light alloy motor housings, light alloy motor housing casting molds play a key role and can ensure product quality and production efficiency.

[0003] Because before casting the alloy motor housing, the mold temperature is low and the temperature difference with the alloy solution is large, when the alloy solution is injected into the inner cavity of the mold, the cast alloy solution is easy to cool and reduce fluidity. At this time, the metal solution flows slowly in the mold and the local temperature is different, which makes it easy for the alloy solution to crystallize too large or incompletely, thereby reducing the casting quality of the alloy motor housing. Secondly, since the inner wall of the mold is coated with a release agent, when the alloy solution is injected into the mold, the alloy solution will melt with a small amount of release agent on the surface of the cast alloy motor housing to form some impurities. At the same time, the alloy solution will also produce an oxidation-reduction reaction during the melting and casting process to form a small amount of impurities. When impurities are formed on the surface of the alloy motor housing in the mold, it is easy for some impurities to fall off inside the mold when the molded alloy motor housing is taken out, which is inconvenient to clean, reducing the working efficiency of this casting mold.

[0004] Therefore, a light alloy motor housing casting mold is proposed. Summary of the invention

[0018] The present invention provides a light alloy motor housing casting mold, which has the following technical points and beneficial effects:

[0019] 1. The present invention uses devices such as a warm pressing plate, a heater and a heating wire. When the alloy solution cools in the mold cavity and has poor fluidity, the heater is powered to operate, so that the heating wire transfers the generated heat to the warm pipe in the warm pressing plate, and then the heat is transferred to the warm pressing plate through the warm pipe. The alloy solution with poor fluidity in the local area of ​​the mold cavity is heated by the warm pressing plate to improve the fluidity, thereby preventing the metal solution from flowing slowly in the mold and the local temperature from being uneven, causing the alloy solution to crystallize too large or incompletely. The alloy solution in the mold cavity is extruded and formed by the warm pressing plate, and the excess alloy solution in the mold cavity is squeezed back by the warm pressing plate through the holes on the centrifugal feeding plate, thereby reducing energy loss and facilitating the heating and reuse of the alloy solution.

[0020] 2. The present invention uses devices such as a warm-pressing plate, a circulation pipe and a fixed rod, and drives the mounting plate to rotate in the reverse direction through a driving wheel. At this time, the cooling water in the water storage tank is transported into the fixed pipe through the fixed rod under the synchronous rotation of the rotating rod. When the cooling water is transported into the fixed pipe, the water source generates pressure in the fixed pipe through the pressure plate and enters the circulation pipe, so that the water source with a lower temperature cools the warm-pressing plate, thereby gradually cooling the motor housing formed in the mold cavity, and the turbofan on the inner side of the rotating rod generates negative pressure under rotation, thereby sucking out impurities that are easily fallen off from the outer surfaces of the warm-pressing plate and the centrifugal feeding plate through the holes on the centrifugal feeding plate, so as to improve the situation where impurities on the motor housing in the mold cavity fall off and are inconvenient to clean.

[0021] 3. The present invention uses devices such as fixed rods, turbofans and limit sliders to absorb impurities, pass through the rotating rod and the limit slider into the connecting pipe. When the cooling water in the water storage tank is driven by the synchronous rotation of the rotating rod and transported into the fixed pipe through the fixed rod, the impurities sucked out of the connecting pipe connected to the rotating rod will be blocked by the filter. When there are many impurities, the filter will gradually block the water source sent into the fixed pipe by the centrifugal pump. At this time, the amount of water discharged from the base water tank and the pedestal water tank through the fixed pipe is reduced, thereby judging the quality of the cast motor housing. At the same time, a magnetic suction plate is provided at the bottom of the water storage tank to absorb the metal impurities flushed into the water storage tank for easy collection and use.

[0022] 4. The present invention uses devices such as a driving wheel and a warm pressing plate. As the alloy solution in the mold cavity is centrifugally cast under the driving rotation of the driving wheel, impurities in the alloy solution will be stratified with the alloy solution under centrifugal force and accumulate on the inner side of the motor housing, that is, the outer surface of the warm pressing plate and the centrifugal feeding plate, thereby facilitating the subsequent cleaning of impurities on the molded motor housing.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figures 1 to 16 , the present invention provides a technical solution for a light alloy motor housing casting mold:

[0042] A light alloy motor housing casting mold comprises a fixed base 1 and a fixed base 2 and a mounting base 3 fixedly mounted on both sides of the fixed base 1, four balancing slide bars 4 are fixedly mounted between the fixed base 2 and the mounting base 3, a driving wheel 102 is provided below one side of the mounting base 3, and the driving wheel 102 is fixedly connected to the fixed base 1, a mounting slide 6 is movably mounted in the middle of the balancing slide bar 4, and the four balancing slide bars 4 pass through the four corners of the mounting slide 6, the inner sides of the mounting base 3 and the mounting slide 6 are fixedly surrounded by a nested ring 601, the outer sides of the nested ring 601 are nested with a rotating disk 15, and the rotating disk 15 is movably mounted on the inner sides of the mounting base 3 and the mounting slide 6, a mounting plate 7 is embedded on one side of the rotating disk 15, a casting mold 8 is fixedly mounted on the mounting plate 7 on one side of the mounting slide 6, and an inner cavity mold 14 is fixedly mounted on the mounting plate 7 on one side of the mounting base 3;

[0043] As an embodiment of the present invention, Figures 1 to 9 As shown, four docking rods 701 are fixedly mounted on the mounting plate 7 on one side of the mounting base 3, and one side of the mounting plate 7 is provided with a mounting hole 702 for being fitted with the rotating disk 15, a mold cavity 802 is provided on the inner side of the casting mold 8, and docking holes 801 for docking with the docking rods 701 are provided at the four corners of the casting mold 8, and a motor housing 17 cast by the inner cavity mold 14 is provided on the inner side of the mold cavity 802;

[0044] During operation, the fixed base 2 and the mounting base 3 are fixedly installed through the fixed base 1, and the balancing slide bar 4 between the fixed base 2 and the mounting base 3 is used to improve the sliding stability of the mounting slide 6 on the fixed base 1. Secondly, the rotating disk 15 is installed in the mounting base 3 and the mounting slide 6 through the nested ring 601. When the mounting plate 7 is installed on the mounting base 3 and the mounting slide 6, the rotating disk 15 is engaged and fixed with the mounting hole 702 on the mounting plate 7, and then the mounting plate 7 is installed on the mounting base 3 and the mounting slide 6. Secondly, when the mounting plates 7 on one side of the mounting base 3 and the mounting slide 6 are docked with each other, the inner cavity mold 14 is docked and inserted into the mold cavity 802 on the casting mold 8 through the engagement of the docking rod 701 and the docking hole 801, so that the motor housing 17 is cast and formed in the inner cavity mold 14 and the mold cavity 802. 15 is arranged as an interlocking movable connection in the mounting base 3 and the mounting slide 6, and when the driving wheel 102 drives the mounting plate 7 on one side of the mounting base 3 to rotate, the rotating disk 15 is rotated in the mounting base 3 and the mounting slide 6. According to Faraday's law of electromagnetic induction, when a conductor moves in a magnetic field or the magnetic field changes, an induced electromotive force will be generated at both ends of the conductor. When the conductor forms a closed loop, the induced electromotive force will cause the free electrons in the conductor to flow, thereby generating current, and then the rotating disk 15 rotates in the mounting base 3 and the mounting slide 6 and generates electrical energy, and the current is rectified by the rectifier provided in the mounting base 3 and the mounting slide 6, so as to power the valve plate 1 303, the valve plate 2 304 and the drive shaft 1107, so that the drive shaft 1107 can provide power to drive the fan valve plate 1106 when it moves with the mounting slide 6.

[0045] As an embodiment of the present invention, Figures 1 to 15As shown, the inner cavity mold 14 includes a warm pressing plate 1401 and a centrifugal feeding plate 1402, and the inner side of the centrifugal feeding plate 1402 is provided with a hole for injecting alloy solution, the inner side of the centrifugal feeding plate 1402 is provided with a fixed tube 1403, the inner side of the centrifugal feeding plate 1402 is fixedly installed with a circulation tube 1408, and the fixed tube 1403 is fixedly connected to the centrifugal feeding plate 1402 through the circulation tube 1408, and the inner side of the centrifugal feeding plate 1402 is equidistantly fixedly surrounded with heaters 1404, and the heaters 1404 are fixedly installed with heating wires 1406, and the heating wires 1406 are fixedly connected to the warm pressing plate 1401, and the inner side of the warm pressing plate 1401 is provided with a spring rod 1405, and the spring rod 1405 is connected to the fixed tube 1403 through the circulation tube 1408;

[0046] A warm pipe is provided inside the warm pressure plate 1401, and the warm pipe and the heating wire 1406 are heat transfer devices, and the warm pipe is connected to the fixed pipe 1403 through the spring rod 1405 and the flow pipe 1408, and a pressure plate 1407 is fixedly installed equidistantly inside the fixed pipe 1403;

[0047] During operation, when the driving wheel 102 drives the mounting plate 7 to rotate, the valve plate 1 303 is opened in the valve slot 305 through the rectifier, and the valve plate 2 304 is closed in the valve slot 305. At this time, the alloy solution enters the centrifugal feeding plate 1402 through the valve plate 1 303. Under the drive of the driving wheel 102, the inner cavity mold 14 on the mounting plate 7 rotates to generate centrifugal force, and then the alloy solution in the centrifugal feeding plate 1402 enters the mold cavity 802 through the hole under the action of the centrifugal force and fills it. The warm pressing plate 1401 is located on the inner side of the centrifugal feeding plate 1402 under the elastic tension of the spring rod 1405. When the alloy solution is cooled in the mold cavity 802 and has poor fluidity, the warm pressing plate 1401 is blocked by the alloy solution with poor fluidity, resulting in that the outer surface of the warm pressing plate 1401 cannot be located on the same circumference as the outer surface of the centrifugal feeding plate 1402. At this time, the heater 1404 is powered by external power supply, so that the heating wire 1406 transfers the generated heat to the warm guide wire in the warm pressing plate 1401. The heat is then transferred to the warm pressing plate 1401 through the warm pipe, and the alloy solution with poor fluidity in the local area of ​​the mold cavity 802 is heated by the warm pressing plate 1401 to improve fluidity. At this time, the resistance of the alloy solution to the warm pressing plate 1401 will be reduced, and under the action of centrifugal force, the warm pressing plate 1401 gradually maintains the same fitting surface with the centrifugal feeding plate 1402, and squeezes the alloy solution in the mold cavity 802 into shape, and the excess alloy solution in the mold cavity 802 will pass through the holes on the centrifugal feeding plate 1402. The impurities are squeezed and reflowed by the warm pressing plate 1401, thereby reducing the loss of alloy raw materials so as to facilitate the heating and reuse of the alloy solution. Since the alloy solution in the mold cavity 802 is centrifugally cast under the driving rotation of the driving wheel 102, the density and specific gravity of the impurities are lower than those of the alloy. The impurities in the alloy solution will be separated from the alloy solution under the centrifugal force and accumulated on the inner side of the motor housing 17, that is, the outer surface of the warm pressing plate 1401 and the centrifugal feeding plate 1402, thereby facilitating the subsequent cleaning of the impurities on the molded motor housing 17.

[0048] After the alloy solution is cast in the mold cavity 802, the driving wheel 102 drives the mounting plate 7 to rotate in the reverse direction, and the valve plate 2 304 is opened through the rectifier, and the valve plate 1 303 is set to be closed in the valve slot 305. At this time, the cooling water in the water storage tank 10 is transported into the fixed pipe 1403 through the fixed rod 1101 under the synchronous rotation of the rotating rod 11. When the cooling water is transported into the fixed pipe 1403, the water source generates pressure in the fixed pipe 1403 through the pressure plate 1407 and enters the circulation pipe 1408. Since the water pressure in the fixed pipe 1403 is gradually reduced toward one end of the butt joint pipe 302 under the obstruction of the water flow by the pressure plate 1407, the water flow with higher water pressure at the front end of the fixed pipe 1403 passes through the warm pipe in the warm pressure plate 1401 from The water flows out from the circulation pipe 1408 at one end of the docking pipe 302, so that the water circulates through the circulation pipe 1408 in the warm conduit inside the warm pressure plate 1401. Since the warm conduit inside the warm pressure plate 1401 is connected with the fixed pipe 1403 through the heater 1404 and the spring rod 1405, the water source with a lower temperature cools the warm pressure plate 1401, thereby gradually cooling the motor housing 17 formed in the mold cavity 802. The turbofan 1104 on the inner side of the rotating rod 11 generates negative pressure under rotation, and then the impurities that are easily fallen off from the outer surfaces of the warm pressure plate 1401 and the centrifugal feeding plate 1402 are sucked away through the holes on the centrifugal feeding plate 1402, so as to improve the situation where impurities on the motor housing 17 in the mold cavity 802 fall off and are inconvenient to clean.

[0049] As an embodiment of the present invention, Figures 3 to 16 As shown, a rotating rod 11 is provided on one side of the mounting slide 6, and the rotating rod 11 is engaged and movably connected with the fixed base 2 and the mounting slide 6, a fixed rod 1101 is provided on the inner side of the rotating rod 11, and the fixed rod 1101 penetrates the inner side of the mounting slide 6 and is engaged and connected with the fixed tube 1403, and a turbofan 1104 is fixedly installed equidistantly on the inner side of the rotating rod 11 and the outer side of the fixed rod 1101;

[0050] A fixed block 1105 is fixedly connected to one side of the fixed rod 1101, and the fixed rod 1101 is fixedly connected to the limit slider 16 through the fixed block 1105. A socket 703 is provided on the mounting plate 7 on one side of the mounting slide 6. A plug 1102 is fixedly connected to one side of the rotating rod 11, and the plug 1102 is engaged with the socket 703. A bevel gear 1103 is fixedly installed on one side of the rotating rod 11. A driving shaft 1107 is provided on the inner side of the plug 1102, and the driving shaft 1107 is engaged and movably connected with the rotating rod 11. A fan valve plate 1106 is fixedly connected to one side of the driving shaft 1107, and one side of the fan valve plate 1106 is fitted with the fixed rod 1101.

[0051] During operation, the plug 1102 is connected and inserted into the socket 703, and then when the driving wheel 102 drives the mounting plate 7 to rotate, the rotating rod 11 is driven to rotate synchronously. When the driving wheel 102 drives the mounting plate 7 to rotate in the reverse direction, since the fixing rod 1101 is fixedly connected to the limiting slider 16 through the fixing block 1105, when the rotating rod 11 rotates in the reverse direction, the turbofan 1104 on the rotating rod 11 generates air suction negative pressure with the turbofan 1104 on the fixing rod 1101 under rotation (since the turbofan 1104 on the rotating rod 11 transfers momentum to the gas molecules during rotation, so that they obtain a certain directional speed and flow in one direction, at this time, the gas passes through the turbofan 1104 fixed on the fixing rod 1101, so that it is compressed during the movement and the pressure gradually increases, thereby forming an exhaust duct for the gas to flow in one direction), thereby removing the impurities on the motor housing 17 that are easy to fall off. The impurities are sucked out through the holes on the centrifugal feeding plate 1402. At this time, the sucked impurities pass through the rotating rod 11 and enter the connecting pipe 13 through the limiting slider 16. Since the connecting pipe 13 connected to the rotating rod 11 through the limiting slider 16 and the connecting pipe 13 connected to the fixed rod 1101 are interconnected, and a filter is provided in the connecting pipe 13 connected to the fixed rod 1101. When the cooling water in the water storage tank 10 is driven by the synchronous rotation of the rotating rod 11 and transported into the fixed pipe 1403 through the fixed rod 1101, the impurities sucked out by the connecting pipe 13 connected to the rotating rod 11 will be blocked by the filter. When there are many impurities, the water source sent into the fixed pipe 1403 by the centrifugal pump 12 is gradually blocked through the filter. At this time, the amount of water discharged from the base water tank 301 and the base water tank 101 through the fixed pipe 1403 is reduced, thereby judging the quality of the cast motor housing 17.

[0052] When the mounting plate 7 and the rotating rod 11 rotate, the drive shaft 1107 is powered by the rectifier to keep the fan valve plate 1106 and the fixed rod 1101 sealed and fitted. At the same time, the turbofan 1104 sucks gas into the rotating rod 11 to generate air pressure to improve the closing effect of the fan valve plate 1106, thereby preventing the alloy solution from flowing into the rotating rod 11 through the centrifugal feeding plate 1402 during transportation. At the same time, the bevel gear 1103 drives the bevel gear rod 1201, so that the centrifugal pump 12 sucks the water in the fixed rod 1101, the fixed pipe 1403 and the warm pipe in the warm pressure plate 1401 to the storage tank. At the same time, the impurities intercepted on the filter screen are flushed into the water tank 10 for collection, so as to collect and recycle the impurities. Since a one-way air valve is provided on the connecting pipe 13 connected to the rotating rod 11, air pressure is generated inside the rotating rod 11 to increase the closing effect of the fan valve plate 1106 to provide air volume. At the same time, the fan valve plate 1106 and the fixed rod 1101 maintain a sealed fit, and the suction force generated when the turbofan 1104 supplies air to the rotating rod 11 is not enough to suck the cooling water in the water tank 10 into the rotating rod 11 through the connecting pipe 13.

[0053] As an embodiment of the present invention, Figures 1 to 12 As shown, a limited sliding rod 9 is fixedly connected to one side of the fixed base 2, and an elastic member for assisting resetting is provided on the inner side of the limited sliding rod 9, a centrifugal pump 12 is provided below the limited sliding rod 9, and the centrifugal pump 12 is fixedly connected to the fixed base 2, a limited sliding block 16 is movably connected to the inner side of the limited sliding rod 9, and the limited sliding block 16 and the rotating rod 11 are nested, a connecting pipe 13 is connected to one side of the fixed rod 1101 through the limited sliding block 16, and the connecting pipe 13 is connected to the centrifugal pump 12, a transmission shaft 1203 is fixedly connected to the inner side of the centrifugal pump 12, a bevel gear rod 1201 is embedded and installed on the inner side of the transmission shaft 1203, and a spring 1202 for elastic expansion and contraction is fixedly connected below the bevel gear rod 1201, and the bevel gear rod 1201 is transmission-connected to the bevel gear 1103;

[0054] During operation, the limit slide block 16 is limitedly installed by the limit slide bar 9. When the motor housing 17 formed in the cavity 802 is taken out, the installation slide table 6 is slid toward the fixed base 2 by driving the slide table 104. Since a spring 1202 is provided under the bevel gear rod 1201, and the bevel gear rod 1201 is movably arranged in the transmission shaft 1203, the bevel gear 1103 pushes and extrude the bevel gear rod 1201 downward. The bevel gear rod 1201 is retracted into the transmission shaft 1203 under the extrusion of the bevel gear 1103, so that the rotating rod 11 and the fixed rod 1101 slide backward under the limit of the limit slide block 16 by the limit slide bar 9, so as to facilitate the removal of the motor housing 17 in the cavity 802 after molding. When the motor housing 17 is taken out of the cavity 802 and continues to be cast, the installation slide block 104 is driven to The platform 6 slides toward the mounting base 3, at which time the bevel gear 1103 pushes and squeezes the bevel gear rod 1201 downward again, and makes the bevel gear 1103 fit with the bevel gear rod 1201, and then the bevel gear 1103 fits and transmits the bevel gear rod 1201, and at the same time, the elastic member in the limiting slide bar 9 is used to assist the limiting slider 16 to slide and reset in the limiting slide bar 9, and at the same time, the limiting slider 16 is used to improve the fit of the rotating rod 11 and the fixed rod 1101 to the centrifugal feeding plate 1402 and the fixed tube 1403. When the bevel gear rod 1201 transmits the centrifugal pump 12, since the bottom of the bevel gear rod 1201 is a polygonal setting, and the inner side of the transmission shaft 1203 is a polygonal setting that fits with the bevel gear rod 1201, the bevel gear 1103 is used to transmit the centrifugal pump 12 through the bevel gear rod 1201.

[0055] As an embodiment of the present invention, Figures 1 to 3As shown, a driving slide bar 103 is fixedly connected to the inner side of the fixed base 1, a driving slide 104 is movably mounted on the driving slide bar 103, and the driving slide 104 is fixedly connected to the bottom of the mounting slide 6, a water storage tank 10 is provided on one side of the fixed base 1, and a connecting pipe 13 is partially immersed in the water storage tank 10, a base water tank 101 is provided on the inner side of the fixed base 1, and the base water tank 101 is connected to the water storage tank 10;

[0056] During operation, the driving slide 104 is installed and used through the driving slide rod 103, and the driving slide 104 is driven to slide on the driving slide rod 103, and then the driving slide 104 drives the installation slide 6 to slide smoothly on the balance slide rod 4. Secondly, since the base water tank 101 is connected with the base water tank 301, the cooling water delivered by the centrifugal pump 12 into the fixed pipe 1403 is returned from the base water tank 301 and the base water tank 101 to the water storage tank 10 through the docking pipe 302. Secondly, a magnetic suction plate is provided at the bottom of the water storage tank 10 to adsorb the metal impurities flushed into the water storage tank 10 for easy collection and use.

[0057] As an embodiment of the present invention, Figure 2 and Fig.13 As shown, a base water tank 301 is provided on the inner side of the mounting base 3, and the base water tank 301 is connected to the base water tank 101, a valve tank 305 is provided on the inner side of the mounting base 3, and a valve plate 1 303 for controlling the conveying of alloy melt and a valve plate 2 304 for controlling the conveying of water flow are provided on the inner side of the valve tank 305, a butt joint pipe 302 is fixedly installed on the inner side of the mounting base 3 through a fixture, and the butt joint pipe 302 is connected to the base water tank 101 through the valve plate 2 304, an alloy melting and casting machine 5 is fixedly installed on one side of the fixed base 1, and a feeding pipe 501 for conveying alloy melt into the centrifugal feeding plate 1402 is fixedly connected to one side of the alloy melting and casting machine 5;

[0058] During operation, when the driving wheel 102 is driven to rotate, the valve plate 1 303 is set to be open in the valve slot 305 through the rectifier, and the valve plate 2 304 is set to be closed in the valve slot 305. When the driving wheel 102 is driven to rotate in the reverse direction, the valve plate 2 304 is opened through the rectifier, and the valve plate 1 303 is set to be closed in the valve slot 305. Then, the feeding and conveying of the alloy solution is controlled by the valve plate 1 303, and the cooling flow of the water flow is controlled by the valve plate 2 304. During feeding, the alloy is melted and conveyed through the alloy melting machine 5, and is conveyed to the centrifugal feeding plate 1402 through the feeding pipe 501 for casting.

[0059] Working principle: when the mounting plate 7 is mounted on the mounting base 3 and the mounting slide 6, the mounting plate 7 is mounted on the mounting base 3 and the mounting slide 6 by the mounting hole 702 on the mounting plate 7 being engaged and fixed, and then the mounting plate 7 is mounted on the mounting base 3 and the mounting slide 6, and then the inner cavity mold 14 is docked and inserted into the mold cavity 802 by the engagement of the docking rod 701 and the docking hole 801, so that the motor housing 17 is cast and formed in the inner cavity mold 14 and the mold cavity 802, and when the driving wheel 102 drives the mounting plate 7 on one side of the mounting base 3 to rotate, the rotating disk 15 is rotated in the mounting base 3 and the mounting slide 6 at the same time, and the rotating disk 15 rotates in the mounting base 3 and the mounting slide 6 and generates electric energy, and the current is rectified by the rectifier provided in the mounting base 3 and the mounting slide 6, so as to supply power to the valve plate 1 303, the valve plate 2 304 and the driving shaft 1107;

[0060] When the driving wheel 102 drives the mounting plate 7 to rotate, the rectifier is used to open the valve plate 1 303 in the valve slot 305 and close the valve plate 2 304 in the valve slot 305. At this time, the alloy solution enters the centrifugal feeding plate 1402. The inner cavity mold 14 on the mounting plate 7 is driven by the driving wheel 102 to rotate to generate centrifugal force. The alloy solution in the centrifugal feeding plate 1402 enters the mold cavity 802 through the hole and fills it. When the alloy solution cools in the mold cavity 802 and has poor fluidity, the warm pressing plate 1401 is unable to maintain the same fitting surface with the centrifugal feeding plate 1402 due to the large resistance of the alloy solution with poor fluidity through the centrifugal force. At this time, the heater 1404 is powered to operate, thereby The heating wire 1406 transfers the generated heat to the warm guide tube in the warm pressing plate 1401, and then transfers the heat to the warm pressing plate 1401 through the warm guide tube. The alloy solution with poor fluidity in the local area of ​​the mold cavity 802 is heated by the warm pressing plate 1401 to improve fluidity. At this time, the resistance of the alloy solution to the warm pressing plate 1401 will be reduced. Under the action of centrifugal force, the warm pressing plate 1401 gradually maintains the same fitting surface with the centrifugal feeding plate 1402, and extrude the alloy solution in the mold cavity 802. The excess alloy solution in the mold cavity 802 will be squeezed back by the warm pressing plate 1401 through the holes on the centrifugal feeding plate 1402, thereby reducing energy loss and facilitating the heating and reuse of the alloy solution.

[0061] After the alloy solution is cast in the mold cavity 802, the driving wheel 102 drives the mounting plate 7 to rotate in the reverse direction, and the valve plate 2 304 is opened through the rectifier, and the valve plate 1 303 is set to be closed in the valve slot 305. At this time, the cooling water in the water storage tank 10 is driven by the synchronous rotation of the rotating rod 11 to be transported into the fixed pipe 1403 through the fixed rod 1101. When the cooling water is transported into the fixed pipe 1403, the water source generates pressure in the fixed pipe 1403 through the pressure plate 1407 and enters the circulation pipe 1408, and the water pressure at the front end of the fixed pipe 1403 is relatively high. The water flows out from the flow pipe 1408 at one end of the butt pipe 302 through the warm conduit in the warm pressure plate 1401, so that the water flows through the flow pipe 1408 and circulates in the warm conduit in the warm pressure plate 1401, so that the water source with a lower temperature cools the warm pressure plate 1401, so as to gradually cool the motor housing 17 formed in the mold cavity 802, and the turbofan 1104 on the inner side of the rotating rod 11 generates negative pressure under rotation, thereby sucking away impurities that are easily detached from the outer surfaces of the warm pressure plate 1401 and the centrifugal feeding plate 1402 through the holes on the centrifugal feeding plate 1402;

[0062] The plug 1102 is connected and inserted into the socket 703, and when the driving wheel 102 drives the mounting plate 7 to rotate, the rotating rod 11 is driven to rotate synchronously. When the driving wheel 102 drives the mounting plate 7 to rotate in the reverse direction, the fixing rod 1101 is fixedly connected to the limit slider 16 through the fixing block 1105, and when the rotating rod 11 rotates in the direction, the turbofan 1104 on the rotating rod 11 generates air suction negative pressure with the turbofan 1104 on the fixing rod 1101 under rotation, and then the impurities that are easy to fall off on the motor housing 17 are sucked out through the holes on the centrifugal feeding plate 1402. At this time, the impurities sucked out are The quality passes through the rotating rod 11 and enters the connecting pipe 13 through the limit slider 16. When the cooling water in the water storage tank 10 is transported into the fixed pipe 1403 through the fixed rod 1101 under the synchronous rotation of the rotating rod 11, the impurities sucked out by the connecting pipe 13 connected to the rotating rod 11 will be blocked by the filter. When there are many impurities, the filter will gradually block the water source sent into the fixed pipe 1403 by the centrifugal pump 12. At this time, the amount of water discharged from the base tank 301 and the base tank 101 through the fixed pipe 1403 is reduced, thereby judging the quality of the cast motor housing 17;

[0063] When the mounting plate 7 and the rotating rod 11 rotate, the driving shaft 1107 is powered by the rectifier so that the fan valve plate 1106 and the fixed rod 1101 are kept sealed and fitted. At the same time, the gas is sucked into the rotating rod 11 through the turbofan 1104 to generate air pressure to improve the closing effect of the fan valve plate 1106, thereby preventing the alloy solution from flowing into the rotating rod 11 through the centrifugal feeding plate 1402 during transportation. At the same time, the bevel gear 1103 drives the bevel gear rod 1201, so that the centrifugal pump 12 sucks the water in the fixed rod 1101, the fixed pipe 1403 and the warm conduit in the warm pressure plate 1401 into the water storage tank 10 for subsequent casting use. At the same time, the impurities intercepted on the filter screen are flushed into the water storage tank 10 for collection, so as to collect and recycle the impurities.

[0064] The limiting slider 16 is installed by the limiting slide bar 9. When the motor housing 17 formed in the mold cavity 802 is taken out, the installation slide 6 is slid toward the fixed base 2 by driving the slide 104. At this time, the bevel gear 1103 pushes and squeezes the bevel gear rod 1201 downward. The bevel gear rod 1201 is retracted into the transmission shaft 1203 under the extrusion of the bevel gear 1103, so that the rotating rod 11 and the fixed rod 1101 slide backward under the limit of the limiting slide bar 9 on the limiting slider 16, so as to facilitate the removal of the motor housing 17 in the mold cavity 802 after molding. When the motor housing 17 is taken out of the mold cavity 802 and continues to be cast, the installation slide 6 is slid toward the installation base 3 by driving the slide 104. At this time, the bevel gear 1103 pushes and squeezes the bevel gear rod 1201 again. The wheel rod 1201 is pushed and squeezed downward, and the bevel gear 1103 is fitted with the bevel gear rod 1201, and then the bevel gear rod 1201 is fitted and transmitted through the bevel gear 1103. At the same time, the elastic member in the limiting slide bar 9 is used to assist the limiting slider 16 to slide and reset in the limiting slide bar 9. At the same time, the limiting slider 16 is used to improve the fit of the rotating rod 11 and the fixed rod 1101 to the centrifugal feeding plate 1402 and the fixed tube 1403. When the bevel gear rod 1201 transmits the centrifugal pump 12, since the bottom of the bevel gear rod 1201 is a polygonal setting, and the inner side of the transmission shaft 1203 is a polygonal setting that fits the bevel gear rod 1201, the bevel gear 1103 is used to transmit the centrifugal pump 12 through the bevel gear rod 1201.

[0065] The driving slide 104 is installed and used by driving the slide bar 103, and the driving slide 104 is driven to slide on the driving slide bar 103, and then the driving slide 104 drives the installation slide 6 to slide smoothly on the balance slide bar 4. Secondly, since the base water tank 101 is connected with the base water tank 301, the cooling water delivered by the centrifugal pump 12 into the fixed pipe 1403 is returned from the base water tank 301 and the base water tank 101 to the water storage tank 10 through the docking pipe 302. Secondly, a magnetic suction plate is provided at the bottom of the water storage tank 10 to adsorb metal impurities flushed into the water storage tank 10 for easy collection and use.
