Description

Technical Field

[0001] This utility model relates to the field of pump and valve manufacturing technology, specifically to a mold for pumps and valves with adjustable engagement height. Background Technology

[0002] Pumps and valves are a general term for pumps and valves, mainly used for fluid transportation. Pumps and valves are often linked together because of their application scenarios. For example, where there are pumps, there are usually valves, and where there are valves, there are often pumps. Pumps and valves that are large or heavy cannot be supported by pipelines alone, so adjustable supports are usually installed to support them. The advantage of adjustable supports is that the connection height can be adjusted so that the pump and valve can be aligned with the pipeline for installation and connection. This type of pump and valve is usually called adjustable connection height pump and valve.

[0003] Whether it is a pump or a valve, they are usually made by casting and die casting processes during production. Molten metal is sent into the mold and the molten metal is filled into the mold cavity by gravity or pressure. After the molten metal solidifies, it is taken out of the mold to obtain the rough blank of the pump or valve shell.

[0004] In existing casting processes, workers typically pour molten metal into a hopper on one side of the flow channel using a ladle. The entire casting device then slowly rotates 90 degrees, allowing gravity to force the molten metal in the hopper through the flow channel into the mold cavity. During this process, because the mold is tilted, the lower part of the flow channel allows molten metal to flow while the upper part expels air, thus improving workpiece quality. However, the amount of molten metal poured into the hopper is mainly controlled by the workers, and there may be instances of too much or too little. If too much molten metal is added, some of it may splash onto the surrounding area because the hopper has rotated 90 degrees to be perpendicular to the ground, resulting in waste and tedious cleaning. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a mold for an adjustable engagement height pump valve to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable engagement height pump valve mold, comprising a first mold and a second mold, wherein a hopper is connected to one side of the first mold via a first mounting plate, and a baffle is connected to one side of the second mold via a second mounting plate, wherein a guide groove is provided at the bottom of the baffle.

[0007] By adopting the above technical solution, when the first mold and the second mold are closed, the baffle will close with the hopper. Since the baffle is short, it avoids excessive obstruction of the hopper, which would make it difficult for workers to add material. After that, the workers pour the molten metal into the hopper. After the material is added, the casting device rotates 90 degrees through the flipping mechanism so that the flow channel faces upward. When the casting device drives the entire mold to rotate, the baffle can effectively reduce the leakage and splashing of molten metal, reduce resource waste and reduce cleaning difficulty. During this process, the setting of the guide chute facilitates the introduction of molten metal into the flow channel, thereby reducing resistance.

[0008] Furthermore, bolts are provided on one side of both the first mounting plate and the second mounting plate.

[0009] By adopting the above technical solution, during installation, the worker attaches the first mounting plate to the first mold, inserts one side of the hopper into the flow channel, and then tightens the bolts to limit the first mounting plate, thereby completing the installation of the hopper. Then, the worker attaches the second mounting plate to the second mold, inserts one side of the baffle into the flow channel, and then tightens the bolts to limit the second mounting plate, thereby completing the installation of the baffle.

[0010] Furthermore, the first mounting plate is detachably connected to the first mold by bolts, and the second mounting plate is detachably connected to the second mold by bolts.

[0011] By adopting the above technical solution, when the structure is damaged, the workers can remove the bolts on the first mounting plate and replace the first mounting plate and the hopper together, or the workers can remove the bolts on the second mounting plate and replace the second mounting plate and the baffle together.

[0012] Furthermore, the feed chute is sloped.

[0013] By adopting the above technical solution, the molten metal can be easily guided into the flow channel through the setting of the material guide trough, thereby reducing resistance.

[0014] Furthermore, the length of the baffle is less than the length of the hopper.

[0015] By adopting the above technical solution, the short length of the baffle avoids excessive obstruction of the hopper, which would make it difficult for workers to add materials. Furthermore, the baffle can effectively reduce the leakage and splashing of molten metal, thereby reducing resource waste and cleaning difficulty.

[0016] Furthermore, positioning grooves are provided on both sides of the interior of the first mold, and the second mold is located on top of the first mold. Positioning rods are connected to both sides of the bottom of the second mold. Cavities are provided on the top of the first mold and the bottom of the second mold, and flow channels are provided on one side of the cavities.

[0017] By adopting the above technical solution, the first mold, the second mold, and the two cores are respectively connected to three sets of cylinders on the casting device. When casting is ready, the operator turns on the casting device to close the first mold and the second mold. At the same time, the positioning rod and positioning groove ensure the closing effect of the first mold and the second mold, preventing the first mold and the second mold from being misaligned. The core is inserted into the cavity, so that the shape inside the cavity is similar to the shape of the valve body or pump body. Then, molten metal is poured into the flow channel to allow the molten metal to enter the cavity. After the molten metal flows into the cavity, it begins to gradually solidify. After solidification, the casting device is flipped back to the initial angle by the flipping mechanism, and the three sets of cylinders separate the first mold and the second mold and pull them out of the cavity. At this time, the operator can take out the valve body or pump body, thus completing the casting work.

[0018] Furthermore, the first mold has a core penetrating both its outer surface and back.

[0019] By adopting the above technical solution, when preparing to cast, the workers open the casting device, close the first mold and the second mold, and insert the core into the cavity, so that the shape inside the cavity is similar to the shape of the valve body or pump body.

[0020] Furthermore, both the hopper and the guide chute are connected to the flow channel.

[0021] By adopting the above technical solution, when the casting device drives the entire mold to rotate, the molten metal in the hopper and guide trough flows into the flow channel under the influence of gravity, and then enters the cavity through the flow channel.

[0022] Furthermore, the bottom of the hopper and the top of the baffle are both connected with reinforcing ribs.

[0023] By adopting the above technical solution, the structural strength of the hopper and the baffle is increased by reinforcing ribs, thereby extending the service life of the hopper and the baffle.

[0024] In summary, the present invention has the following main advantages: This invention, through the arrangement of a hopper, a baffle, and a guide chute, ensures that when the first mold and the second mold are closed, the baffle closes with the hopper. Because the baffle is relatively short, it avoids excessive obstruction of the hopper, preventing difficulties for workers in adding material. When the casting device rotates the entire mold, the baffle effectively reduces molten metal leakage and splashing, minimizing resource waste and cleaning difficulty. The guide chute facilitates the introduction of molten metal into the flow channel, reducing resistance; thus effectively reducing molten metal leakage and splashing, thereby minimizing resource waste and cleaning difficulty.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] Example 1:

[0030] A mold for an adjustable engagement height pump valve, such as Figures 1-4 As shown, the system includes a first mold 1 and a second mold 2. A hopper 9 is connected to one side of the first mold 1 via a first mounting plate 8, and a baffle 11 is connected to one side of the second mold 2 via a second mounting plate 10. The length of the baffle 11 is less than the length of the hopper 9. Bolts 13 are provided on one side of both the first mounting plate 8 and the second mounting plate 10. The first mounting plate 8 is detachably connected to the first mold 1 via bolts 13, and the second mounting plate 10 is detachably connected to the second mold 2 via bolts 13. A guide groove 12 is provided at the bottom of the baffle 11. The guide groove 12 is sloping. Both the hopper 9 and the guide groove 12 are connected to the flow channel 7. When the first mold... When mold 1 and the second mold 2 are closed, the baffle 11 will close with the hopper 9. Since the baffle 11 is relatively short, it avoids excessive obstruction of the hopper 9, which would make it difficult for the workers to add material. After that, the workers pour the molten metal into the hopper 9. After the material is added, the casting device rotates 90 degrees through the flipping mechanism so that the flow channel 7 faces upward. When the casting device drives the entire mold to rotate, the baffle 11 can effectively reduce the leakage and splashing of molten metal, reduce resource waste and reduce cleaning difficulty. During this process, the molten metal is easily guided into the flow channel 7 through the guide groove 12, thereby reducing resistance.

[0031] See Figure 1 , Figure 3 and Figure 4In the above embodiment, positioning grooves 3 are provided on both sides of the interior of the first mold 1. The second mold 2 is located on top of the first mold 1. Positioning rods 4 are connected to both sides of the bottom of the second mold 2. Cavities 5 are provided on the top of the first mold 1 and the bottom of the second mold 2. A flow channel 7 is provided on one side of the cavity 5. A core 6 penetrates the outer surface and back of the first mold 1. The first mold 1, the second mold 2 and the two cores 6 are respectively connected to three sets of cylinders on the casting device. When casting is ready, the operator turns on the casting device to close the first mold 1 and the second mold 2. At the same time as the molds are closed, the positioning rods 4 and the positioning grooves 3 ensure the closing effect of the first mold 1 and the second mold 2, preventing the first mold 1 and the second mold 2 from being misaligned. The core 6 is inserted into the cavity 5, so that the shape inside the cavity 5 is similar to the shape of the valve body or pump body. After the molten metal flows into the cavity 5, it begins to solidify gradually. After solidification, the three sets of cylinders separate the first mold 1 and the second mold 2 and pull out the cavity 5. At this time, the operator can take out the valve body or pump body, thus completing the casting work.

[0032] Example 2:

[0033] Based on the above embodiment one, the following settings are now adopted to increase structural strength.

[0034] See Figures 1-4 In the above embodiment, the bottom of the hopper 9 and the top of the baffle 11 are both connected with reinforcing ribs 14. The reinforcing ribs 14 increase the structural strength of the hopper 9 and the baffle 11, thereby extending the service life of the hopper 9 and the baffle 11.

[0035] The implementation principle of this utility model is as follows: First, the first mold 1, the second mold 2, and the two cores 6 are respectively connected to three sets of cylinders on the casting device; when preparing to cast, the operator turns on the casting device to close the first mold 1 and the second mold 2. At the same time as the molds are closed, the positioning rod 4 and the positioning groove 3 ensure the closing effect of the first mold 1 and the second mold 2, preventing the first mold 1 and the second mold 2 from being misaligned, and the core 6 is inserted into the cavity 5, so that the shape inside the cavity 5 is similar to the shape of the valve body or pump body; it should be noted that the cavity 5 in this technical solution is exemplified by a butterfly valve, and the shape of the cavity 5 is not limited and can be customized according to different products. Some valve bodies or pump bodies may use more cores 6 or cores 6 of other shapes to achieve casting valve bodies or pump bodies with more complex shapes; When the first mold 1 and the second mold 2 are closed, the baffle 11 will close with the hopper 9. Since the baffle 11 is relatively short, it avoids excessive obstruction of the hopper 9, which would make it difficult for the workers to add material. After that, the workers pour the molten metal into the hopper 9. After the material is added, the casting device rotates 90 degrees through the flipping mechanism so that the flow channel 7 faces upward. When the casting device drives the entire mold to rotate, the baffle 11 can effectively reduce the leakage and splashing of molten metal, reduce resource waste and reduce cleaning difficulty. During this process, the guide chute 12 facilitates the introduction of molten metal into the flow channel 7, thereby reducing resistance. After the molten metal flows into the cavity 5, it begins to solidify gradually. Once solidification is complete, the casting device flips back to its initial angle via a flipping mechanism, and three sets of cylinders separate the first mold 1 and the second mold 2 and extract the cavity 5. At this point, the operator can remove the valve body or pump body blank, thus completing the casting process.
