Technical Field
[0001] This invention relates to the field of zinc-copper alloy casting technology, specifically to a zinc-copper alloy casting equipment with the function of reducing component segregation. Background Technology
[0002] Centrifugal casting is a technique and method in which liquid metal is injected into a high-speed rotating mold, causing the molten metal to fill the mold and form a casting through centrifugal motion. Centrifugal casting is widely used in the casting of cylindrical pipe fittings. During casting, the mold rotates at high speed, and then the molten metal is injected into the mold through a guide tube. Under the action of centrifugal force, the molten metal forms a workpiece. Due to the centrifugal motion, the liquid metal can fill the mold well in the radial direction and form a free surface of the casting. A cylindrical inner hole can be obtained without a core, which helps to remove gas and inclusions from the liquid metal.
[0003] However, existing centrifugal casting equipment can cause intragranular segregation in the metal parts due to the cooling rate, which in turn affects the quality of the finished metal parts. The current solution is to transfer the metal parts to another device after casting to reduce the intragranular segregation, which leads to a decrease in production efficiency. Summary of the Invention
[0004] The purpose of this invention is to provide a zinc-copper alloy casting device that reduces component segregation, thereby solving the problems raised in the prior art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a zinc-copper alloy casting equipment with a function of reducing component segregation, comprising a casting equipment body and a controller.

[0007] Furthermore, the cooling assembly is installed at the bottom of the casting cylinder. The cooling assembly includes an installation cylinder and multiple sets of heat absorption plates. The multiple sets of heat absorption plates are installed at equal intervals at the bottom of the casting cylinder. The installation cylinder is installed at the output end of the casting cylinder. Multiple sets of cooling plates are installed at equal intervals inside the installation cylinder. One end of the cooling plate and the heat absorption plate are connected by a wire, and the other end of the cooling plate and the heat absorption plate are connected to the controller by a wire.
[0008] Furthermore, the heat-absorbing plate and the cooling plate are composed of two different semiconductors and metals, with the heat-absorbing plate being the cold end and the cooling plate being the hot end.
[0009] Furthermore, the injection assembly includes a mounting plate, on which a support frame is mounted. A pouring tank and an injection tank are mounted between the support frames. Both ends of the pouring tank are connected to the support frame via bearings. A pouring motor is mounted on the side of the pouring tank. A conduit is mounted at the output end of the injection tank, and the conduit cooperates with the casting cylinder.
[0010] Furthermore, the sealing assembly includes a sliding plate and a sealing plate. A support block is installed above the sliding plate. Multiple sealing cylinders are equidistantly installed on the support block near one end of the centrifugal casting assembly. A limit ring is installed on the other end of the sealing cylinder. A clamping cylinder is installed outside the limit ring. An arc-shaped block is provided inside the limit ring. The clamping cylinder cooperates with the arc-shaped block. The sealing plate cooperates with the casting cylinder. A sealing block is installed on the end of the sealing plate near the discharge port of the casting cylinder. The arc-shaped block cooperates with the sealing block.
[0011] Furthermore, the support platform is provided with multiple sets of drive slots. One set of drive slots is provided with a demolding assembly and a demolding motor. The demolding assembly includes a support plate, a fixing block is installed above the support plate, a fixing rod is installed at the output end of the fixing block, a stripping sleeve and multiple sets of stripping cylinders are installed on the fixing rod, the stripping cylinders are equidistantly installed on the fixing rod, the output end of the stripping cylinder is connected to the stripping sleeve, multiple sets of support rods are installed at the other end of the stripping sleeve, the other end of the support rod is connected to a stripping rod, the stripping rod is pressed against the outside of the support rod, the stripping rod is slidably connected to the support rod, and the bottom of the stripping rod is connected to the fixing rod through a bearing.
[0012] Furthermore, another set of the drive slots is provided with an annealing assembly, which includes an annealing cylinder and a slider. The annealing cylinder and the slider are respectively installed inside the drive slot. The output end of the annealing cylinder is connected to the slider, and an induction coil is installed above the slider.
[0013] Furthermore, the coating assembly includes a storage tank and multiple sets of adjusting cylinders. The multiple sets of adjusting cylinders are respectively installed on the top of the mounting frame. The coating cylinder is installed at the bottom of the mounting frame. The output end of the adjusting cylinder is connected to the coating cylinder. The output end of the coating cylinder is equipped with a coating rod. The output end of the coating rod is equipped with multiple sets of nozzles. The nozzles are connected to the storage tank.
[0014] Furthermore, the controller is installed on the side of the main body of the casting equipment, the controller is connected to the main body of the casting equipment, and the controller is equipped with a control panel.
[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] 1. When in use, this device can reduce component segregation during casting. Even if component segregation exists, the device can reduce and remove intragranular segregation through the annealing component, so that the device can increase production efficiency while reducing component segregation of metal parts during casting.
[0017] 2. When the casting cylinder of this device is shaping the molten metal solution, the cooling component at the bottom of the casting cylinder can evenly absorb the heat generated by the casting cylinder. This is because the heat absorption plates are installed at equal intervals at the bottom of the casting cylinder. Since the heat absorption plates and the cooling plates are connected to the controller through wires, when the heat absorption plates absorb heat, the electrons in the heat absorption plates will move into the cooling plates and accumulate in the cooling plates, thereby creating a temperature difference between the heat absorption plates and the cooling plates. After passing through the cooling plates, the metal parts can be cooled down steadily.
[0018] 3. When in use, the demolding component of this device can separate the metal parts inside the casting cylinder. Specifically, the demolding motor drives the rotating rod in the drive slot to rotate, which in turn moves the support plate towards the casting cylinder. During this process, the annealing component is also positioned between the demolding component and the casting cylinder, allowing the fixing rod to pass through the annealing component for subsequent annealing. After the fixing rod enters the casting cylinder, the demolding cylinder pushes the demolding sleeve forward, which in turn moves the support rod. When the support rod moves, because it is at the bottom of the stripper rod and is slidably connected to it, the height of the stripper rod is raised as the support rod moves forward, allowing the stripper rod to press against the inner wall of the metal parts. Afterward, when the demolding motor reverses, it drives the support plate to reset and also pulls the metal parts out of the casting cylinder, thus completing the demolding process.
[0019] 4. The annealing component of this device can perform an annealing process on metal parts, thereby reducing or eliminating intragranular segregation on the metal parts. In specific use, when the demolded metal parts pass through the induction coil, the alternating current flowing through the induction coil generates an alternating magnetic field through the workpiece. This magnetic field causes eddy currents in the metal parts, thereby heating them. Then, the metal parts are slowly cooled down, which can reduce or eliminate intragranular segregation in the metal parts. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] Example: Figures 1-9 As shown, the present invention provides a zinc-copper alloy casting equipment with a function of reducing component segregation, including a casting equipment body 1 and a controller 12. The casting equipment body 1 includes a support platform 11, on which a centrifugal casting component 2, a drive component 3, a demolding component 4, a coating component 5 and an annealing component 6 are arranged. A mounting frame is fixedly installed above the support platform 11, and the coating component 5 and multiple spray heads are installed at the bottom of the mounting frame. The centrifugal casting component 2 cooperates with the drive component 3, the demolding component 4 and the coating component 5 respectively. A cooling component 9 is installed at the bottom of the centrifugal casting component 2. The cooling component 9 can uniformly accelerate the shaping of copper parts, and the annealing component 6 can eliminate intragranular segregation on copper parts.
[0032] When using this device, firstly, a release coating is applied to the centrifugal casting component 2 via the coating component 5. The release coating provides a heat-insulating protective layer for the metal mold, preventing and mitigating the direct erosion and thermal shock of the mold by the molten metal solution, reducing the internal stress of the mold wall, and extending the service life of the metal parts. Then, the drive component 3 drives the centrifugal casting component 2 to rotate. Next, molten metal solution is injected into the centrifugal casting component 2. Under the action of centrifugal force, the molten metal solution casts the corresponding metal parts according to the shape of the mold. While the metal parts are being removed by the release component 4, the cooling component 9 at the bottom of the centrifugal casting component 2 can uniformly cool the metal parts. Due to the cooling rate, the formed metal parts often have intragranular segregation. Therefore, during the demolding process, the annealing component 6 can anneal the metal parts to eliminate intragranular segregation. After annealing, depending on the material, it can be rapidly cooled by a spray head or cooled on its own to finally eliminate the segregation of the metal parts.
[0033] like Figures 1-2 As shown, in this embodiment, specifically, the centrifugal casting assembly 2 includes a casting cylinder 21 and an injection assembly 7. The injection assembly 7 cooperates with the input end of the casting cylinder 21, and a sealing assembly 8 is provided at the output end of the casting cylinder 21. The casting cylinder 21 is installed above the drive assembly 3. The drive assembly 3 includes a drive motor 31 and a drive rod 32. The drive motor 31 is connected to the drive rod 32. Multiple sets of drive wheels 33 are installed on the drive rod 32. Multiple sets of drive grooves 211 are provided on the casting cylinder 21, and the drive wheels 33 are matched with the drive grooves 211.
[0034] When in use, the centrifugal casting assembly 2 can cast metal parts by using centrifugal force. Specifically, the drive motor 31 on the drive assembly 3 can drive the drive rod 32 to rotate. When both drive rods 32 on both sides are rotating, the casting cylinder 21 can be rotated. After the coating assembly 5 applies a uniform release coating to the inner wall of the casting cylinder 21, the injection assembly 7 injects molten metal solution into the casting cylinder 21. Under the action of centrifugal force, the molten metal solution is shaped in the casting cylinder 21 according to the shape of the inner wall of the casting cylinder 21, thereby completing the casting of the metal part.
[0035] like Figures 6-7 As shown in this embodiment, specifically, a cooling component 9 is installed at the bottom of the casting cylinder 21. The cooling component 9 includes an installation cylinder 91 and multiple sets of heat absorption plates 92. The multiple sets of heat absorption plates 92 are equidistantly installed at the bottom of the casting cylinder 21. The installation cylinder 91 is installed at the output end of the casting cylinder 21. Multiple sets of cooling plates 93 are equidistantly installed inside the installation cylinder 91. One end of the cooling plate 93 is connected to one end of the heat absorption plate 92 through a wire, and the other end of the cooling plate 93 and the heat absorption plate 92 is connected to the controller 12 through a wire.
[0036] When the casting cylinder 21 of this device is shaping the molten metal solution, the cooling component 9 at the bottom of the casting cylinder 21 can evenly absorb the heat generated by the casting cylinder 21. In specific use, because the heat-absorbing plates 92 are equidistantly installed at the bottom of the casting cylinder 21, and because the heat-absorbing plates 92 and the cooling plates 93 are connected to the controller 12 through wires, when the heat-absorbing plates 92 absorb heat, the electrons in the heat-absorbing plates 92 will move into the cooling plates 93 and accumulate in the cooling plates 93, thereby creating a temperature difference between the heat-absorbing plates 92 and the cooling plates 93. Since the heat-absorbing plates 92 are located at the bottom of the casting cylinder 21, they can directly absorb the heat generated by the casting cylinder 21 during casting. The controller 12 is connected to the cooling plates 93 and the heat-absorbing plates 92 mainly because the controller 12 can monitor the current between the cooling plates 93 and the heat-absorbing plates 92 in real time, thereby supplementing the power to the cooling component 9 when the current is low.
[0037] like Figures 6-7 As shown, in this embodiment, specifically, the heat-absorbing plate 92 and the cooling plate 93 are composed of two different semiconductors and metals, with the heat-absorbing plate 92 being the cold end and the cooling plate 93 being the hot end;
[0038] Since the heat absorber plate 92 and the cooling plate 93 are composed of two different semiconductors and metals, the heat absorber plate 92 can absorb the heat emitted by the casting cylinder 21 when the heat absorber plate 92 and the cooling plate 93 are energized. As a result, the electrons in the heat absorber plate 92 can move to the cooling plate 93 and accumulate in the cooling plate 93.
[0039] like Figure 1 and Figure 5 As shown, in this embodiment, specifically, the injection assembly 7 includes a mounting plate 71, a support frame 72 is mounted on the mounting plate 71, a pouring tank 73 and an injection tank 74 are mounted between the support frames 72, the two ends of the pouring tank 73 are connected to the support frame 72 through bearings, a pouring motor 75 is mounted on the side of the pouring tank 73, and a conduit is mounted on the output end of the injection tank 74, the conduit is engaged with the casting cylinder 21;
[0040] When in use, the injection component 7 of this device can add a fixed amount of molten metal solution to the centrifugal casting component 2. Specifically, the fixed amount of molten metal solution needs to be injected into the pouring tank 73 first. Then, the injection component 7 will move towards the centrifugal casting component 2, so that the conduit connects with the feed port of the centrifugal casting component 2. Then, the pouring motor 75 will start, driving the pouring tank 73 to rotate, so that the pouring tank 73 tilts towards the injection tank 74, thereby moving the molten metal solution in the pouring tank 73 into the injection tank 74. The conduit on the injection tank 74 can inject the molten metal solution into the centrifugal casting component 2. After the molten metal solution is injected, the injection component 7 will be controlled to return to its original position, thus completing the injection process of molten metal solution.
[0041] like Figure 2 and Figure 7 As shown in this embodiment, specifically, the sealing component 8 includes a sliding plate 81 and a sealing plate 82. A support block 83 is installed above the sliding plate 81. Multiple sealing cylinders 84 are equidistantly installed on one end of the support block 83 near the centrifugal casting component 2. A limit ring 85 is installed on the other end of the sealing cylinder 84. A clamping cylinder 86 is installed outside the limit ring 85. An arc-shaped block 87 is provided inside the limit ring 85. The clamping cylinder 86 cooperates with the arc-shaped block 87. The sealing plate 82 cooperates with the casting cylinder 21. A sealing block 88 is installed on one end of the sealing plate 82 near the discharge port of the casting cylinder 21. The arc-shaped block 87 cooperates with the sealing block 88.
[0042] When using this device, the output end of the casting cylinder 21 needs to be sealed by the sealing component 8 to prevent the molten metal solution inside the casting cylinder 21 from being thrown out during rotation. Specifically, the sealing plate 82 is installed inside the casting cylinder 21, and then the clamping cylinder 86 retracts the arc-shaped block 87, thus separating the sealing plate 82 from the other components. After molding is complete, the sealing cylinder 84 pushes the limiting ring 85 closer to the sealing plate 82. When the sealing block 88 is between the limiting rings 85... When the clamping cylinder 86 is activated, it pushes the arc-shaped block 87. When multiple arc-shaped blocks 87 approach each other, they squeeze the sealing block 88 and clamp it. Since the sealing block 88 and the sealing plate 82 are integrated, when the sealing cylinder 84 retracts, it moves the sealing block 88 and separates the sealing plate 82 from the casting cylinder 21, thus ending the sealing. Afterward, the sealing assembly 8 returns to the starting position under the retraction of the side cylinder until the next casting.
[0043] like Figure 3 and Figure 8 As shown in this embodiment, specifically, the support platform 11 is provided with multiple sets of drive slots 211. Each set of drive slots 211 is provided with a demolding assembly 4 and a demolding motor 48. The demolding assembly 4 includes a support plate 41. A fixing block 42 is installed above the support plate 41. A fixing rod 43 is installed at the output end of the fixing block 42. A stripping sleeve 44 and multiple sets of stripping cylinders 45 are installed on the fixing rod 43. The stripping cylinders 45 are equidistantly installed on the fixing rod 43. The output end of the stripping cylinder 45 is connected to the stripping sleeve 44. Multiple sets of support rods 46 are installed at the other end of the stripping sleeve 44. A stripping rod 47 is connected to the other end of the support rod 46. The stripping rod 47 is pressed against the outside of the support rod 46. The stripping rod 47 is slidably connected to the support rod 46. The bottom of the stripping rod 47 is connected to the fixing rod 43 through a bearing.
[0044] When in use, the demolding assembly 4 of this device can separate the metal parts inside the casting cylinder 21. Specifically, the demolding motor 48 drives the rotating rod inside the drive groove 211 to rotate, thereby moving the support plate 41 towards the casting cylinder 21. During this process, the annealing assembly 6 is also positioned between the demolding assembly 4 and the casting cylinder 21, allowing the fixing rod 43 to pass through the annealing assembly 6 for subsequent annealing. After the fixing rod 43 enters the casting cylinder 21, the demolding cylinder pushes the demolding sleeve forward, thereby pushing the support rod 46 to move. When the support rod 46 moves, because it is located at the bottom of the stripping rod 47 and is slidably connected to it, the height of the stripping rod 47 is raised as the support rod 46 moves forward, allowing the stripping rod 47 to abut against the inner wall of the metal parts. Afterward, when the demolding motor 48 reverses, it drives the support plate 41 to reset and simultaneously pulls the metal parts out of the casting cylinder 21, thus completing the demolding process.
[0045] like Figure 3 and Figure 9 As shown, in this embodiment, specifically, another set of drive slots 211 is provided with an annealing assembly 6. The annealing assembly 6 includes an annealing cylinder 61 and a slider 62. The annealing cylinder 61 and the slider 62 are respectively installed inside the drive slot 211. The output end of the annealing cylinder 61 is connected to the slider 62. An induction coil 63 is installed above the slider 62.
[0046] The annealing component 6 of the device can perform an annealing process on the metal parts, thereby reducing or eliminating intragranular segregation on the metal parts. In specific use, when the demolded metal parts pass through the induction coil 63, the alternating current flowing through the induction coil 63 generates an alternating magnetic field through the workpiece. This magnetic field causes eddy currents in the metal parts, thereby heating them. Then, the metal parts are slowly cooled down, which can reduce or eliminate intragranular segregation in the metal parts.
[0047] like Figure 1 and Figure 4 As shown, in this embodiment, specifically, the coating component 5 includes a storage tank 51 and multiple sets of adjusting cylinders 52. The multiple sets of adjusting cylinders 52 are respectively installed on the top of the mounting frame. A coating cylinder 53 is installed at the bottom of the mounting frame. The output end of the adjusting cylinder 52 is connected to the coating cylinder 53. A coating rod 54 is installed at the output end of the coating cylinder 53. Multiple nozzles 55 are installed at the output end of the coating rod 54. The nozzles 55 are connected to the storage tank 51.
[0048] After a set of metal parts is cast, the coating component 5 of the device sprays a fixed amount of release coating onto the inner wall of the casting cylinder 21. This prevents and slows down the direct erosion and thermal shock of the mold by the molten metal solution during subsequent casting, reduces the internal stress of the mold wall, and extends the service life of the metal parts. In specific use, after a set of metal parts is cast, the adjusting cylinder 52 pushes the coating cylinder 53 downward until the output end of the coating cylinder 53 is parallel to the center point of the casting cylinder 21. Then, the coating cylinder 53 pushes the coating rod 54 into the casting cylinder 21. In order to ensure that the release coating is evenly covered inside the casting cylinder 21, the drive component 3 drives the casting cylinder 21 to rotate. So when the nozzle 55 sprays the release coating, the casting cylinder 21 can evenly spray the release coating onto the inner wall of the casting cylinder 21 under the action of centrifugal force.
[0049] like Figure 1 As shown in this embodiment, specifically, a controller 12 is installed on the side of the casting equipment body 1. The controller 12 is connected to the casting equipment body 1, and a control panel is provided on the controller 12.
[0050] When in use, the main body 1 of the casting equipment is controlled and monitored by the controller 12, which is equipped with a control panel. Thus, the staff can indirectly control and monitor the main body 1 of the casting equipment through the control panel.
[0051] Working Principle: When using this device, firstly, a release coating is applied to the centrifugal casting component 2 via the coating component 5. This release coating provides a heat-insulating protective layer for the metal mold, preventing and mitigating direct erosion and thermal shock from the molten metal, reducing internal stress in the mold wall, and extending the service life of the metal parts. Then, the drive component 3 rotates the centrifugal casting component 2. Next, molten metal is injected into the centrifugal casting component 2. Under centrifugal force, the molten metal casts the corresponding metal parts according to the mold shape. While the metal parts are being removed by the release component 4, the cooling component 9 at the bottom of the centrifugal casting component 2 uniformly cools the metal parts. Due to the cooling rate, the formed metal parts often exhibit intragranular segregation. Therefore, during the demolding process, the annealing component 6 anneales the metal parts, eliminating intragranular segregation. After annealing, depending on the material, rapid cooling via a spray nozzle or self-cooling can be selected to ultimately eliminate the segregation of the metal parts.
[0052] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
