Description

[0001] The invention belongs to the technical field of metal casting and relates to a copper plate casting forming device and method. Background Art

[0002] Red copper sheet is a metal sheet rolled from high-purity electrolytic copper, named for its purple-red surface. As an industrial foundation, red copper sheet boasts excellent electrical and thermal conductivity, ductility, and corrosion resistance. It is widely used in power electronics, architectural decoration, chemical equipment, machinery manufacturing, and artistic creation. The production process for red copper sheet typically involves casting.

[0003] Currently, in the casting process of copper plates, the production process mainly includes steps such as melting, pouring, cooling and post-processing. The existing method is mainly to inject high-temperature liquid copper into the mold, and then wait for it to cool and solidify naturally. However, due to the effect of surface tension in the process of copper liquid transforming from liquid to solid, the surface of the cooled copper plate presents an undesirable curved surface shape. This non-planar surface state cannot meet the needs of subsequent processing or direct application. Therefore, additional mechanical processing must be performed to achieve the required flatness standard. This process not only increases the processing cost of the material, but also significantly prolongs the production cycle and reduces the overall production efficiency. Summary of the Invention

[0026] The present invention will be described in detail below with reference to the accompanying drawings.

[0027] A copper plate casting device, such as Figures 1-4 As shown, it includes a base plate 1, a mounting frame 2, a swivel 3, a forming mold frame 5, a liquid adding mechanism, a driving mechanism and a flattening mechanism. The mounting frame 2 is connected to the middle of the top of the base plate 1, and the swivel 3 is rotatably connected to the mounting frame 2. The top of the swivel 3 is connected to the forming mold frame 5. The casting copper liquid can be added to the forming mold frame 5, and the copper liquid is cooled and formed in the forming mold frame 5. The base plate 1 is provided with a liquid adding mechanism for adding copper liquid, and a driving mechanism is provided between the swivel 3 and the mounting frame 2. The driving mechanism is used to drive the swivel 3 to rotate, and the swivel 3 is provided with a flattening mechanism for flattening the copper plate.

[0028] like Figure 2 and Figure 3 As shown, the liquid adding mechanism includes a connecting frame 41, a liquid adding frame 42, a liquid injection pipe 43 and a solenoid valve 44. The connecting frame 41 is connected to the left side of the top of the bottom plate 1, the top of the connecting frame 41 is connected to the liquid adding frame 42, and the right side of the bottom of the liquid adding frame 42 is connected to the liquid injection pipe 43. The solenoid valve 44 is provided at the liquid injection pipe 43. The end of the liquid injection pipe 43 is aligned with the forming mold frame 5. The copper liquid is added to the liquid adding frame 42. The copper liquid in the liquid adding frame 42 can be added to the forming mold frame 5 through the liquid injection pipe 43.

[0029] like Figure 2 As shown, the driving mechanism includes an inner ring gear 51, a driving motor 52 and a driving gear 53. The inner side of the rotating ring 3 is connected to the inner ring gear 51, and the inner ring of the mounting frame 2 is installed with a driving motor 52. The output shaft of the driving motor 52 is connected to the driving gear 53, and the driving gear 53 is engaged with the inner ring gear 51, so that the operation of the driving motor 52 can drive the rotating ring 3 to rotate through the driving gear 53 and the inner ring gear 51.

[0030] like Figure 3 and Figure 4As shown, the flattening mechanism includes a guide rod 61, a lifting frame 62 and a pressing plate 63. A plurality of groups of guide rods 61 are connected to the top of the rotating ring 3 at even intervals along the circumference. The number of groups of the guide rods 61 is consistent with the number of the forming mold frames 5. Each group of guide rods 61 is provided with three. A lifting frame 62 is slidably connected between the three guide rods 61 in the same group. The lifting frame 62 can slide up and down along the guide rods 61. A pressing plate 63 is connected to the lifting frame 62. The pressing plate 63 is located above the forming mold frame 5 so that the pressing plate 63 can be moved downward to be pressed into the forming mold frame 5, so as to flatten the top surface of the formed copper plate.

[0031] When it is necessary to cast a copper plate, this device can be used. When in use, first add copper liquid into the liquid adding frame 42. At this time, the solenoid valve 44 is in the closed state. Then the drive motor 52 can be controlled to operate to drive the drive gear 53 to rotate. When the drive gear 53 rotates, it can drive the inner ring gear 51 to rotate. When the inner ring gear 51 rotates, it can drive the swivel 3 to rotate. When the swivel 3 rotates, it can drive the forming mold frame 5 to rotate. When the forming mold frame 5 rotates to the bottom of the liquid injection pipe 43, it can pull the pressing plate 63 to move upward. At this time, the end of the liquid injection pipe 43 is located below the pressing plate 63. Then you can When the solenoid valve 44 is controlled to open, the copper liquid will flow into the injection pipe 43, and then flow into the forming mold frame 5 through the injection pipe 43. After the copper liquid is added, the solenoid valve 44 is controlled to close. At this time, the pressing plate 63 is released. Under the action of gravity, the pressing plate 63 moves down and presses on the copper liquid to flatten the top surface of the copper liquid. Then the copper liquid gradually cools and forms in the forming mold frame 5, thereby realizing the casting and forming of the copper plate. In this way, the casting work of the copper plate can be realized, and the top surface of the copper plate can be flattened during casting to avoid the top surface of the copper plate from arching and requiring subsequent processing, which is more convenient to operate.

[0032] like Figure 4 and Figure 5 As shown, it also includes a unloading mechanism, and the lifting mechanism includes a lifting plate 71, a lifting frame 72, a support rod 73 and an arc-shaped extrusion frame 74. A plurality of lifting frames 72 are connected to the rotating ring 3 at even intervals along the circumference, and the number of the lifting frames 72 is consistent with the number of the forming mold frames 5. The top of the lifting frame 72 is connected to a lifting plate 71, and the lifting plate 71 is located in the forming mold frame 5. The upward movement of the lifting plate 71 can push out the copper plate formed in the forming mold frame 5. The lower part of the lifting frame 72 is connected to a support rod 73, and the right side of the top of the base plate 1 is connected to an arc-shaped extrusion frame 74. The front side of the arc-shaped extrusion frame 74 is tilted downward, and the support rod 73 can move to contact the inclined part of the arc-shaped extrusion frame 74, and then be squeezed by the arc-shaped extrusion frame 74, so that the support rod 73 moves upward.

[0033] When the swivel 3 rotates, it will drive the lifting frame 72, the lifting plate 71 and the support rod 73 to rotate together. When the support rod 73 moves to contact the arc-shaped extrusion frame 74, the copper plate has been cast and formed. At this time, the support rod 73 continues to move and will be squeezed upward by the arc-shaped extrusion frame 74. The support rod 73 will drive the lifting frame 72 to move upward when it moves upward. The lifting frame 72 can drive the lifting plate 71 to move upward when it moves upward. The upward movement of the lifting plate 71 can push the formed copper plate upward. When the lifting plate 71 moves to the limit, the bottom of the copper plate is slightly higher than the top of the forming mold frame 5. At this time, the copper plate can be directly pushed out. In this way, the formed copper plate can be taken out more conveniently, and the operation is more convenient.

[0034] like Figure 6 and Figure 7 As shown, a lifting mechanism is also included, and the lifting mechanism includes a connecting ring 81 and an arc-shaped guide bar 82. The inner ring of the mounting frame 2 is connected to the connecting ring 81, and the outer side of the connecting ring 81 is connected to the arc-shaped guide bar 82. The right front side of the arc-shaped guide bar 82 is set to be tilted downward. The lifting frame 62 is connected to an extension shaft 83, and the arc-shaped guide bar 82 is located at the moving track of the extension shaft 83, so that the extension shaft 83 moves and contacts with the tilted part of the arc-shaped guide bar 82, and then the extension shaft 83 continues to move and moves upward along the tilted part of the arc-shaped guide bar 82, thereby driving the lifting frame 62 to move upward.

[0035] When the swivel 3 rotates, it can drive the lifting frame 62 to rotate together. When the lifting frame 62 rotates, it will drive the extension shaft 83 to rotate. When the extension shaft 83 rotates to contact the arc-shaped guide bar 82, the extension shaft 83 continues to rotate and will be squeezed and moved upward by the arc-shaped guide bar 82. The extension shaft 83 can drive the lifting frame 62 to move upward when it moves upward. When the lifting frame 62 moves upward, it will drive the pressing plate 63 to move upward. When the molding mold frame 5 moves to below the injection pipe 43, the pressing plate 63 corresponding to the molding mold frame 5 is also in an upward state. After the injection is completed, the molding mold frame 5 continues to rotate, and the extension shaft 83 on the pressing plate 63 corresponding to the molding mold frame 5 is also disengaged from the arc-shaped guide bar 82. Under the action of gravity, the pressing plate 63 moves downward, thereby achieving the effect of automatically controlling the up and down movement of the pressing plate 63, which is more convenient to operate.

[0036] like Figure 8 and Figure 9As shown, it also includes a pushing mechanism, which includes a triangular extrusion block 91, a guide frame 92, a connecting frame 93, a discharge plate 94, an elastic member 95 and a contact shaft 96. The lower right side of the connecting ring 81 is connected to the triangular extrusion block 91, and the left and right sides of the molding mold frame 5 are connected to the guide frames 92. A connecting frame 93 is slidably connected between the two guide frames 92. An elastic member 95 is connected between the connecting frame 93 and the guide frame 92. The elastic member 95 is a connecting spring. The guide frame 92 is close to the connecting ring 81. A contact shaft 96 is connected to one side of the connecting frame 93, and the triangular extrusion block 91 is located at the moving track of the contact shaft 96, so that the contact shaft 96 moves and contacts the triangular extrusion block 91, thereby being squeezed by the triangular extrusion block 91 to move the contact shaft 96 downward. The front and rear sides of the connecting frame 93 are provided with inclined grooves, and a discharge plate 94 is slidably connected between the two inclined grooves. The discharge plate 94 is located above the forming mold frame 5. When the connecting frame 93 moves downward, the discharge plate 94 is squeezed by the inclined groove to move, so that the discharge plate 94 moves above the forming mold frame 5.

[0037] When the forming mold frame 5 rotates, it will drive the guide frame 92 and the connecting frame 93 to rotate together. When the connecting frame 93 rotates, it will drive the contact shaft 96 to rotate. When the contact shaft 96 rotates to contact the triangular extrusion block 91, the lifting plate 71 just pushes up the copper plate. At this time, the contact shaft 96 continues to rotate and will be squeezed downward by the triangular extrusion block 91. The downward movement of the contact shaft 96 can drive the connecting frame 93 to move downward, and the elastic member 95 is compressed. When the connecting frame 93 moves downward, it can squeeze the unloading plate 94 outward through the inclined groove thereon. The unloading plate 94 can push out the formed copper plate when it moves. In this way, the cast copper plate can be automatically unloaded without manual unloading processing, and the operation is more convenient.

[0038] like Figure 5 As shown, a contact wheel 10 is also included. The middle part of the support rod 73 is connected to the contact wheel 10. The arc-shaped extrusion frame 74 is located at the moving track of the contact wheel 10. The contact wheel 10 contacts the arc-shaped extrusion frame 74 and is squeezed by the arc-shaped extrusion frame 74, thereby driving the support rod 73 to move. The rolling of the contact wheel 10 can reduce the friction during contact.

[0039] This embodiment also provides a copper plate casting method, the specific steps are as follows: S1: Add copper liquid into the liquid adding frame 42, control the driving motor 52 to operate and drive the driving gear 53 to rotate; S2: The driving gear 53 rotates to drive the inner gear ring 51 to rotate, the rotation of the inner gear ring 51 drives the rotating ring 3 to rotate, and the rotation of the rotating ring 3 drives the forming mold frame 5 to rotate; S3: The molding mold frame 5 rotates to the bottom of the injection tube 43, pulling the pressing plate 63 upward. At this time, the end of the injection tube 43 is located below the pressing plate 63; S4: The solenoid valve 44 is controlled to open, and the copper liquid flows into the injection pipe 43 and then flows into the forming mold frame 5 through the injection pipe 43 to realize the addition of the copper liquid. After the addition is completed, the solenoid valve 44 is controlled to close; S5: Loosen the pressing plate 63, move the pressing plate 63 downward and press on the copper liquid to flatten the top surface of the copper liquid. The copper liquid gradually cools and forms in the forming mold frame 5, completing the copper plate casting work.
