Description

Technical Field

[0001] The invention belongs to the technical field of elbow casting, and specifically relates to an elbow casting forming machine. Background Art

[0002] An elbow casting machine is a device specially used for producing pipe elbows. It injects molten metal or other alloys into a pre-designed mold, solidifies it in the mold, and finally forms a pipe elbow of the desired shape. The elbow casting machine usually includes a furnace system, a mold, an injection system, a cooling system, a mold removal and unloading system, and a control system, etc., which are used to realize the automation and precise control of the entire casting process. The equipment can be adjusted and optimized according to production needs to achieve efficient, stable and high-quality production.

The present invention has a reasonable structure, and the cooling effect is improved by arranging a pumping mechanism, a driving mechanism and a transmission mechanism. The process does not require the use of a driving source such as a circulating pump, which can greatly reduce the production cost. By arranging a stirring mechanism, the coolant in the cooling box can be fully stirred during the pumping process, so as to avoid injecting water vapor that has not been cooled and liquefied into the mold body, thereby affecting the heat dissipation effect.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand: the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figures 1 to 8As shown, the present invention provides a technical solution: an elbow casting machine, comprising a workbench 1, a cooling station 37 and an injection station 38 are arranged directly above the workbench 1, the cooling station 37 and the injection station 38 each include four groups of half elbow molds 2, a splicing assembly is arranged on the outside of each group of half elbow molds 2, the splicing assembly is used to splice every two half elbow molds 2 to form a complete casting mold, a transposition assembly is arranged on the top between the cooling station 37 and the injection station 38, the transposition assembly is used to exchange the position between the cooling station 37 and the injection station 38, a blanking assembly is arranged at the cooling station 37, the blanking assembly is used to add molten material to the casting mold at the cooling station 37, a condensation assembly is arranged at the injection station 38, the condensation assembly is used to cool the casting mold at the injection station 38, and a driving assembly is arranged at the injection station 38, the driving assembly is used to drive the casting mold at the injection station 38 to separate.

[0031] During operation: During casting, in the existing elbow casting machine, after the elbow mold is cooled, the mold needs to be removed to take out the elbow solid therein, and the mold needs to be separated by a tool to take out the elbow solid therein. When removing and separating the mold, a tool needs to be used for operation. If the operation is improper or the force is too large, it is easy to cause damage or deformation of the mold, affecting the service life and production quality of the mold. In addition, the existing device needs to be carried out separately during molten material injection and mold cooling, which consumes a lot of time, affects work efficiency, and increases the production cycle. Through the embodiment of the present scheme, during specific use, the molten material is first slowly added to the multiple half-elbow molds 2 merged together at the cooling station 37 through the blanking component. After the addition is completed, the position change component is started to exchange the position of the cooling station 37 with the injection station 38. At this time, the half-elbow mold 2 to which the molten material has been added in the cooling station 37 is located at the injection station 38 and is cooled by the condensation mechanism. The half-elbow mold 2 at the injection station 38 will The material is injected through the unloading assembly at the cooling station 37, and the half elbow mold 2 at the injection station 38 starts the driving assembly after cooling is completed, so that the two half elbow molds 2 of each group are separated, and the solid elbow therein can fall out for demolding. The separated half elbow mold 2 is then merged through the driving assembly. At this time, the injection station 38 exchanges position with the cooling station 37 again, and the unloading, cooling and collection are repeated. Through the above embodiment, the cooling station 37 and the injection station 38 continuously exchange positions, so that the unloading and cooling processes can be carried out simultaneously, and the positions can be exchanged after the two groups of stations are completed, which can minimize the waiting time in production, realize a more continuous and efficient production process, thereby improving the overall production efficiency, and the solid elbow after cooling can be collected without taking out the mold, avoiding shape changes or damage that may be caused by taking out the mold, while shortening the production cycle, improving production efficiency, and being more stable and reliable.

[0032] like Figure 4 and Figure 7 As shown, the outer wall of each half elbow mold 2 is fixedly connected with a half movable outer ring 3, the inner walls on both sides of each two half movable outer rings 3 are threadedly connected with a bidirectional threaded rod 4, a connecting column 5 is fixedly connected between one side of each two adjacent bidirectional threaded rods 4, and one side of each half elbow mold 2 is fixedly connected with a half blocking plate 8.

[0033] During operation: when the half elbow mold 2 located at the injection station 38 completes cooling to form a solid elbow, the multiple bidirectional threaded rods 4 at the injection station 38 will be driven to rotate simultaneously by starting the driving assembly, and the bidirectional threaded rods 4 will drive the two half-movable outer rings 3 in each group to move away from each other. At this time, every two half elbow molds 2 merged together begin to separate until the solid elbow formed in the inner wall can completely fall out. After collection, each group of half elbow molds 2 are merged again through the driving assembly to facilitate the next injection work. Through the above embodiment, the effect of removing the elbow without removing the mold is achieved, and the effect of quick removal and avoiding mold damage is achieved.

[0034] like Figures 2 to 4 As shown, the outer wall of each connecting column 5 is rotatably connected to a clamping ring 6, the outer wall of each half elbow mold 2 is fixedly connected to a half magnet outer ring 7, the adjacent sides of each group of two half magnet outer rings 7 have opposite magnetic properties, the top side of each half magnet outer ring 7 is fixedly connected to a connecting tube 9, the top of the connecting tube 9 is fixedly connected to a slider 10, the outer walls of the sliders 10 on each side are slidably connected to a fixed slide seat 11, and one end of each clamping ring 6 is fixedly connected to one side of the fixed slide seat 11.

[0035] During operation: when the half elbow mold 2 is merged, the half magnet outer ring 7 at the other end of the half elbow mold 2 will fit tightly against each other through magnetic force, and the other end of the half elbow mold 2 will fit tightly against each other to prevent leakage after the molten material is added, and when the bidirectional threaded rod 4 rotates to drive the two half movable outer rings 3 in each group to move away from each other, the two half movable outer rings 3 in each group are driven to move away from or closer to each other through the mutual cooperation between the slider 10 connected to the half magnet outer ring 7 and the fixed slide seat 11. Through the above embodiment, the compactness of the half elbow mold 2 is enhanced when it is merged, and leakage after the molten material is injected is avoided.

[0036] like Figure 1 and Figure 5As shown, a vertical platform 30 is fixedly connected between one side of each group of two fixed slides 11, a rotating plate 18 is fixedly connected between the bottoms of each two vertical platforms 30, a rotating column 19 is fixedly connected to the top of the center of the rotating plate 18, an upper horizontal plate 26 is fixedly connected to the outer side of the workbench 1, the top of the rotating column 19 is rotatably connected to the inner wall of the top of the upper horizontal plate 26, and the bottom of the rotating column 19 is rotatably connected to the inner wall at the center of the workbench 1.

[0037] During operation: When the cooling station 37 and the injection station 38 need to be replaced, starting the replacement component will drive the rotating column 19 to rotate 180 degrees. The rotating column 19 is located at the center of the workbench 1 and its position will not change. When the rotating column 19 rotates 180 degrees, it will drive the rotating plate 18 to rotate 180 degrees. The rotating plate 18 will drive the multiple groups of half-elbow molds 2 at the cooling station 37 and the injection station 38 to rotate through the vertical table 30, thereby achieving the effect of position exchange.

[0038] like Figure 5 to Figure 6 As shown, the driving assembly includes a motor 22, the output shaft of the motor 22 is rotatably connected to the upper horizontal plate 26, the outer wall of the output shaft of the motor 22 is fixedly connected to a disc 24, the inner wall of the disc 24 is provided with an internal tooth groove 25, the eccentric part of the disc 24 is fixedly connected to a fixing rod 23, one side of the disc 24 is fixedly connected to an intermittent gear 20, the top of the intermittent gear 20 is fixedly connected to a rhombus 21, and the rhombus 21 and the intermittent gear 20 are both fixedly connected to the outer wall of the rotating column 19.

[0039] During operation: start the motor 22, and its output shaft will drive the disc 24 to rotate. When the fixed rod 23 at the eccentric part of the disc 24 rotates to the diamond-shaped part 21, it will touch the outer side of the diamond-shaped part 21 and make the diamond-shaped part 21 rotate a little. The diamond-shaped part 21 will drive the intermittent gear 20 to rotate a little. At this time, when the disc 24 continues to rotate, the inner tooth groove 25 will just mesh with the teeth on one side of the intermittent gear 20, so that the intermittent gear 20 can rotate exactly 180 degrees. Therefore, the rotating column 19 just rotates 180 degrees, completing the position exchange between the cooling station 37 and the injection station 38. After the rotation is completed, the diamond-shaped part 21 can return to its original position to facilitate the next movement.

[0040] like Figure 1 and Figure 5 As shown, an arc-shaped slider 31 is symmetrically fixedly connected to the bottom of the rotating plate 18 , a circular annular groove 29 is opened on the inner wall at the center of the workbench 1 , and the outer wall of the arc-shaped slider 31 is slidably connected and matched with the inner wall of the circular annular groove 29 .

[0041] During operation: when the rotating plate 18 rotates, the cooperation between the arc-shaped slider 31 and the circular ring groove 29 makes the rotation of the rotating plate 18 more stable and does not deviate from the path.

[0042] like Figure 1 and Figure 7 As shown, one side of the two groups of connecting columns 5 is fixedly connected with a transmission ring 12, and the outer walls of the two groups of transmission rings 12 are transmission-connected with a transmission belt 13. The driving assembly includes a fixed frame plate 14, and the fixed frame plate 14 is fixedly installed on one side of the workbench 1. The outer side of the fixed frame plate 14 is fixedly connected with a motor 15, and the output shaft of the motor 15 is fixedly connected with an electronic telescopic rod 16. One end of the electronic telescopic rod 16 is fixedly connected with a driving ring 17, and the driving ring 17 is transmission-connected to the inner wall of one of the transmission belts 13.

[0043] During operation: when the half-elbow mold 2 at the injection station 38 needs to start the driving assembly for demolding, the driving ring 17 is telescoped to the inner wall of the transmission belt 13 through the electronic telescopic rod 16, and then the motor 15 is started, and its output shaft will drive the driving ring 17 to rotate through the electronic telescopic rod 16. The rotation of the driving ring 17 will drive the transmission ring 12 to rotate through the transmission belt 13, and the transmission ring 12 will drive the various bidirectional threaded rods 4 at the injection station 38 to rotate through the connecting column 5, so that each group of two half-elbow molds 2 move away from each other to achieve the demolding effect. After completion, the driving ring 17 retracts.

[0044] like Figure 1 and Figure 8 As shown, a bottom plate 32 is fixedly connected to the bottom of the workbench 1, a collecting box 33 is arranged on the top of the bottom plate 32, a sponge pad 34 is arranged on the inner wall of the collecting box 33, and a plurality of discharge ports 35 are opened on the inner wall of the workbench 1, and the discharge ports 35 are located directly below the half elbow mold 2.

[0045] During operation: during demoulding, the solid elbow falls into the collection box 33 through the discharge port 35 and is cushioned by the sponge pad 34 to avoid strong collision that may damage the newly formed solid elbow.

[0046] like Figure 1 and Figure 8 As shown, the condensation assembly includes a cold air inlet 36 , which is opened on the inner wall of the workbench 1 , and a condensation pipe is installed on the inner wall of the cold air inlet 36 .

[0047] During operation: a cold air inlet 36 is opened through the inner wall of the workbench 1, and a condenser box structure is added at the bottom plate 32, and a condenser pipe is inserted through the cold air inlet 36, so that cold air can be continuously introduced into the injection station 38 for cooling treatment.

[0048] like Figure 1 and Figure 5As shown, the feeding assembly includes a feeding funnel 27, which is fixedly installed on the inner wall of the upper horizontal plate 26. A plurality of feeding pipes 28 are fixedly connected to the bottom of the feeding funnel 27. The openings of the feeding pipes 28 are located directly above the half elbow mold 2 at the cooling station 37.

[0049] During operation: melt is added into the feeding funnel 27, and the melt is injected into the half elbow mold 2 at the cooling station 37 through the feeding pipe 28.

[0050] Working process: First, add molten material into the feeding funnel 27, and allow the half elbow mold 2 at the cooling station 37 to receive the molten material through the feeding pipe 28, and inject the molten material. Open a cold air inlet 36 through the inner wall of the workbench 1, and add a condensation box structure at the bottom plate 32. The condensation pipe is inserted through the cold air inlet 36, so that the injection station 38 can continuously supply cold air for cooling treatment.

[0051] Then, after 37 and 38 are respectively injected with molten material and cooled, the motor 22 is started, and its output shaft will drive the disc 24 to rotate. When the fixed rod 23 at the eccentric part of the disc 24 rotates to the diamond-shaped part 21, it will touch the outer side of the diamond-shaped part 21 and make the diamond-shaped part 21 rotate a little. The diamond-shaped part 21 will drive the intermittent gear 20 to rotate a little. At this time, when the disc 24 continues to rotate, the inner tooth groove 25 will just mesh with the teeth on one side of the intermittent gear 20, so that the intermittent gear 20 can just rotate 180 degrees. Therefore, the rotating column 19 just rotates 180 degrees. The rotating column 19 is located at the center of the workbench 1 and its position will not change. When the rotating column 19 rotates 180 degrees, it will drive the rotating plate 18 to rotate 180 degrees. The rotating plate 18 will drive the cooling station 37 and the multiple groups of half-side elbow molds 2 at the injection station 38 to rotate through the vertical table 30, thereby achieving the effect of position exchange.

[0052] Secondly, after the transposition, after the 2 at 38 is cooled, the drive ring 17 is extended to the inner wall of the transmission belt 13 through the electronic telescopic rod 16, and then the motor 15 is started, and its output shaft will drive the drive ring 17 to rotate through the electronic telescopic rod 16, and the rotation of the drive ring 17 will drive the transmission ring 12 to rotate through the transmission belt 13, and the transmission ring 12 will drive the various bidirectional threaded rods 4 at the injection station 38 to rotate through the connecting column 5, and the bidirectional threaded rod 4 will drive the two half-side moving outer rings 3 in each group to move away from each other. At this time, every two half-side elbow molds 2 merged together begin to separate until the solid elbow formed in the inner wall can completely fall out to achieve the demoulding effect, and the solid elbow falls into the collection box 33 through the discharge port 35, and is cushioned by the sponge pad 34. After completion, the drive ring 17 retracts.

[0053] Finally, when the half elbow mold 2 is merged, the half magnet outer ring 7 at the other end of the half elbow mold 2 will fit tightly against each other through magnetic force, and the other end of the half elbow mold 2 will fit tightly against each other to prevent leakage after the molten material is added. When the bidirectional threaded rod 4 rotates to drive the two half movable outer rings 3 in each group to move away from each other, the slider 10 and the fixed slide seat 11 connected at the half magnet outer ring 7 cooperate with each other to drive the two half movable outer rings 3 in each group to move away from or closer to each other.
