Description

Technical Field

[0001] The utility model relates to the technical field of casting, in particular to a casting processing and casting device. Background Art

[0002] Before casting, the metal block needs to be melted in a melting furnace. When the metal block is heated to a liquid state in the melting furnace, it needs to be rotated by a rotating mechanism on one side of the melting furnace, and finally the entire melting furnace is rotated to an inclined state. This inclined state allows the liquid metal to flow out from the liquid outlet at the upper end of the melting furnace, and the liquid metal flows into the mold. The rotating mechanism and the liquid outlet at the upper end of the melting furnace constitute a casting device;

[0003] However, during the rotation of this casting device, the molten furnace is tilted. This tilt causes the liquid metal to flow from a high place to a low place. Splashing may occur during the flow. The splashing liquid metal will damage the surrounding metal. The splashing liquid metal will also cause harm to the safety of personnel, resulting in low safety performance of the existing casting device. Therefore, in order to solve the above problems, we propose a casting processing casting device. Utility Model Content

[0004] The purpose of the utility model is to provide a casting processing casting device to solve the problem proposed in the above background technology that the existing casting device causes the molten furnace to tilt during the rotation process, and this tilt causes the liquid metal to flow from a high place to a low place. Splashing may occur during the flow process. This splashing liquid metal will damage the surrounding metal. The splashing liquid metal will also cause damage to the safety of personnel, resulting in the low safety performance of the existing casting device.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a casting processing and casting device, comprising an outer furnace, the upper end of the outer furnace is connected to a cover plate by a thread, a pressure relief valve is fixedly connected to one side of the upper end of the cover plate, the lower end of the outer furnace is fixedly connected to a finished plate, the lower end of the finished plate is provided with a forming mold, the middle of the lower end of the finished plate is provided with a liquid outlet, an inner furnace is provided inside the outer furnace, an electromagnetic induction coil is provided between the outer furnace and the inner furnace, and a metal liquid control mechanism is provided in the middle of the electromagnetic induction coil.

[0006] Preferably, a push-pull column is provided through the middle of the cover plate, and a blocking block is fixedly connected to the lower end of the push-pull column.

[0007] Preferably, a discharge port for a cone is provided in the middle of the inner furnace, the discharge port for the cone and the liquid outlet are connected, and the blocking block is extruded and located in the discharge port for the cone.

[0008] Preferably, a guide layer A is provided around the inner cavity end surface of the inner furnace, and a guide layer B is provided around the inner cavity end surface of the guide layer A.

[0009] Preferably, a guide seam B is formed between the interior of the inner furnace and the guide layer A, the guide seam B and the liquid outlet in the middle of the bottom plate are connected, a guide seam A is formed between the interior of the guide layer A and the guide layer B, a liquid through hole is provided in the middle of the bottom end of the guide layer B, and the liquid through hole is connected to the guide seam A.

[0010] Preferably, a hydraulic column is fixedly connected to the middle of the upper end of the cover plate, and a piston plate is fixedly connected to the output end of the lower side of the hydraulic column.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In one embodiment of the utility model, the push-pull column is manually pulled upward, and the push-pull column drives the blocking block to move upward, thereby causing the blocking block to move upward from the discharge port for the cone, and finally causing the discharge port for the cone and the liquid outlet to no longer be blocked by the blocking block, and the liquid metal inside the inner furnace is discharged from the liquid outlet into the forming mold;

[0013] This arrangement and operation does not require the outer furnace to be rotated and tilted to allow the liquid metal inside to flow out. Instead, it is only necessary to pull the push-pull column and the blocking block at the lower end, so that the liquid metal inside the inner furnace flows downward due to gravity, thereby avoiding the splashing phenomenon of the existing outer furnace during the process of rotating and tilting the liquid metal, and improving the safety performance of the overall casting device.

[0014] 2. In another embodiment of the present invention, since a liquid through hole is provided in the middle of the lower end of the guide layer B, the liquid metal flows into the guide gap A between the guide layer A and the guide layer B. When the metal block is completely melted, the user starts the hydraulic column to make the output end of the lower end of the hydraulic column move downward and drive the piston plate to move downward. At this time, the piston plate moves downward inside the guide layer B and presses the liquid metal. The liquid metal is pressed and flows gradually upward from the guide gap A and overflows the edge of the upper end of the guide layer A. Then the liquid metal flows into the guide gap B and finally flows out from the liquid outlet at the lower end into the molding mold.

[0015] This arrangement drives the piston plate downward through the output end on the lower side of the hydraulic column, gradually squeezes out the liquid metal, and finally flows downward through the liquid outlet. This arrangement avoids the splashing phenomenon of the existing external furnace during the rotation and pouring of liquid metal, and further improves the safety performance of the overall casting device.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figures 1 to 3 The utility model provides two embodiments: a casting processing and casting device, comprising an outer furnace 1, the upper end of the outer furnace 1 is connected with a cover plate 18 by threads, and a pressure relief valve 2 is fixedly connected to one side of the upper end of the cover plate 18, and the pressure relief valve 2 is used to release the gas pressure inside the outer furnace 1 to avoid the expansion of the gas inside the outer furnace 1 after heating, and the lower end of the outer furnace 1 is fixedly connected with a formed plate 3, the lower end of the formed plate 3 is provided with a forming mold 5, and the middle of the lower end of the formed plate 3 is provided with a liquid outlet 4, the inner furnace 7 is provided inside the outer furnace 1, and an electromagnetic induction coil 6 is provided between the outer furnace 1 and the inner furnace 7, and a metal liquid control mechanism is provided in the middle of the electromagnetic induction coil 6;

[0022] The outer furnace 1 is made of a heat-insulating material, which insulates the heat inside the device to prevent heat dissipation. The electromagnetic induction coil 6 is wound around the outer surface of the inner furnace 7. When in use, the cover plate 18 is opened to separate the threads inside the cover plate 18 and the threads outside the outer furnace 1. Then, the metal to be heated is placed inside the inner furnace 7. Then, the cover plate 18 is covered on the upper end of the outer furnace 1. The electromagnetic induction coil 6 is energized. The electromagnetic induction coil 6 generates heat to the inner furnace 7 due to the principle of electromagnetic induction, thereby melting the metal inside the inner furnace 7 into liquid.

[0023] like Figure 2As shown, one embodiment of the utility model provided is as follows: a push-pull column 10 is provided through the middle of the cover plate 18, a blocking block 9 is fixedly connected to the lower end of the push-pull column 10, a conical material discharge port 8 is provided in the middle of the inner furnace 7, the conical material discharge port 8 and the liquid outlet 4 are provided through, the blocking block 9 is squeezed in the conical material discharge port 8, a guide layer A12 is provided around the inner cavity end surface of the inner furnace 7, and a guide layer B13 is provided around the inner cavity end surface of the guide layer A12;

[0024] The push-pull column 10, the blocking block 9 and the conical discharge port 8 in this embodiment constitute a metal liquid control mechanism, wherein the metal block inside the inner furnace 7 is melted into a liquid state due to the principle of electromagnetic induction of the electromagnetic induction coil 6, and the conical discharge port 8 in the middle of the inner furnace 7 cannot allow the liquid metal to flow out due to the blockage of the blocking block 9. If the liquid metal inside the inner furnace 7 is to flow into the forming mold 5, it is necessary to manually pull the push-pull column 10 upward, and the push-pull column 10 drives the blocking block 9 to move upward, thereby causing the blocking block 9 to move upward from the conical discharge port 8, and finally causing the conical discharge port 8 and the liquid outlet 4 to no longer be blocked by the blocking block 9, and the liquid metal inside the inner furnace 7 is discharged from the liquid outlet 4 into the forming mold 5;

[0025] Compared with the prior art, the above arrangement does not require the outer furnace 1 to be rotated and tilted as a whole to allow the liquid metal inside to flow out. It only requires pulling the push-pull column 10 and the blocking block 9 at the lower end to allow the liquid metal inside the inner furnace 7 to flow downward due to gravity, thereby avoiding the splashing phenomenon of the liquid metal in the existing outer furnace 1 during the rotation and tilting process, and improving the safety performance of the overall casting device.

[0026] like Figure 3 As shown, another embodiment provided by the utility model: a guide seam B16 is formed between the interior of the inner furnace 7 and the guide layer A12, the guide seam B16 and the liquid outlet 4 at the middle of the bottom plate 3 are connected, a guide seam A15 is formed between the interior of the guide layer A12 and the guide layer B13, a liquid through hole 14 is penetrated in the middle of the bottom end of the guide layer B13, the liquid through hole 14 is connected with the guide seam A15, a hydraulic column 11 is fixedly connected to the middle of the upper end of the cover plate 18, and a piston plate 17 is fixedly connected to the output end of the lower side of the hydraulic column 11;

[0027] The guide layer A12, the guide layer B13, the hydraulic column 11 and the piston plate 17 in this embodiment constitute a metal liquid control mechanism, and the metal block is placed inside the guide layer B13, wherein the guide layer A12 and the guide layer B13 are both fixed on the end wall inside the inner furnace 7. The guide layer A12 and the guide layer B13 are both made of heat-conducting materials, so that after the electromagnetic induction coil 6 is energized, the heat generated by the inner furnace 7 can be transferred to the guide layer A12 and the guide layer B13. This arrangement enables the metal in the guide layer B13 to melt into a liquid state;

[0028] Since a liquid through hole 14 is provided in the middle of the lower end of the guide layer B13, the liquid metal flows into the guide gap A15 between the guide layer A12 and the guide layer B13. When the metal block is completely melted, the user starts the hydraulic column 11 so that the output end of the lower end of the hydraulic column 11 moves downward and drives the piston plate 17 to move downward. At this time, the piston plate 17 moves downward inside the guide layer B13 and presses the liquid metal. The liquid metal is pressed and flows gradually upward from the guide gap A15 and overflows the edge of the upper end of the guide layer A12. Then the liquid metal flows into the guide gap B16 and finally flows out from the liquid outlet 4 at the lower end into the molding mold 5.

[0029] The setting of the guide layer A12 and the guide layer B13 in the molten metal control mechanism in this embodiment prevents the liquid metal from overflowing. The piston plate 17 is driven downward by the output end of the lower side of the hydraulic column 11 to gradually squeeze out the liquid metal and finally flow downward through the liquid outlet 4. This setting avoids the splashing phenomenon of the existing outer furnace 1 during the process of rotating and pouring the liquid metal, and further improves the safety performance of the overall casting device.

[0030] It is obvious 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 present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
