Description

Technical Field

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

[0002] The main function of the balanced weight casting is to ensure that the mechanical equipment can remain stable, balanced and reliable when it rotates at high speed or vibrates. Unbalanced castings will cause vibration and noise in the mechanical equipment, affecting the normal operation and service life of the equipment. Through balanced weight castings, the vibration of the power transmission system can be reduced, the noise level can be reduced, and the working efficiency and running stability of the equipment can be improved. Unbalanced castings will cause additional loads and wear on the parts and bearings of the equipment, shortening the service life of the equipment. Balanced weight castings can make the rotating parts evenly stressed, reduce wear and damage, extend the life of the equipment, and reduce maintenance costs. Casting is a device used for casting and molding materials such as metals and plastics. Casting is one of the important processes in the manufacturing industry, involving the melting, injection of metals or other materials into molds, and solidification molding. Casting process technology includes smelting technology, pouring technology, solidification technology, etc., which has an important impact on the design and operation of casting equipment.

[0003] Most of the existing counterweight castings are manufactured by casting. In the case of ordinary casting, the material distribution inside the casting is uneven, which will lead to uneven weight distribution of the casting. Since the distribution of the material cannot be accurately controlled, it is difficult to achieve accurate balance. In addition, during the ordinary casting process, due to the fluidity of the molten metal and the shrinkage during the solidification process, defects such as pores and shrinkage cavities are easily generated. In addition, the casting efficiency is low due to the single casting. In order to solve the above problems, a casting device for counterweight casting is proposed. Utility Model Content

[0004] The utility model aims to solve the problems that when pouring a balanced weight casting, the material inside the casting is unevenly distributed, resulting in uneven weight distribution of the casting, and the fluidity of the molten metal and the shrinkage during solidification easily produce defects such as pores and shrinkage holes, making it difficult to achieve accurate balance, and the pouring efficiency is low during casting, thereby proposing a pouring device for a balanced weight casting.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A pouring device for a balanced weight casting, comprising a device base, a casting outer column and a vibration fixed block, wherein a fixing circle is fixedly installed on the outside of the device base, a sliding protrusion is fixedly installed on the outside of the casting outer column, a mold assembly is slidably connected to the outside of the sliding protrusion, and the mold assembly comprises a No. 3 mold, a No. 2 mold and a No. 1 mold;

[0007] The vibrating fixed block is fixedly installed on the outside of the casting outer column, and the vibrating fixed block is connected to a fluid vibration component, which includes a sliding rod, a motor, a rotating disk and a vibration spring.

[0012] Preferably, a fourth groove is provided on the outside of the device base, a fixing circle is fixedly installed on the outside of the device base, and an air outlet is provided on the outside of the fixing circle.

[0013] Preferably, a groove for preventing adhesion is provided on the outside of the cast outer column, and a casting hole is provided on the outside of the cast outer column.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. In the utility model, by setting up a mold assembly, the overall pouring of multiple castings can be achieved, which greatly improves the production efficiency. By pouring multiple castings at one time, the time required for pouring a single casting can be saved, thereby improving the overall production efficiency. Pouring multiple castings at the same time can ensure that they are subject to similar process conditions and environmental influences in the same pouring process, thereby improving the consistency and stability of the castings, which is conducive to ensuring product quality.

[0017] 2. In the utility model, by controlling the fluid vibration component, the fluidity of the liquid metal during pouring can be increased.

The liquid metal with good fluidity can wet the mold surface more evenly, which is beneficial to improving the surface finish and precision of the casting.

[0018] 3. In the utility model, the heating electromagnetic coil is designed to cooperate with the fluid vibration component, so that the liquid metal can be heated during pouring to avoid the reduction of fluidity. Heating the liquid metal helps to promote the discharge of gas from the metal. By increasing the temperature of the metal, the solubility of the gas is reduced, and the bubbles will escape from the metal more easily, reducing the presence of pores and bubbles in the casting. Heating the liquid metal can improve its wettability, making it easier to contact the mold surface and fill fine structures, which can improve the surface quality of the casting, reduce the occurrence of defects, and greatly improve the quality of the cast casting.

[0026] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Embodiment 1

[0028] like Figure 1-6 As shown, a pouring device for a balanced weight casting comprises a device base 1, a casting outer column 2 and a vibration fixing block 3, a fixing circle 24 is fixedly installed on the outside of the device base 1, a sliding protrusion 11 is fixedly installed on the outside of the casting outer column 2, a mold assembly is slidably connected to the outside of the sliding protrusion 11, and the mold assembly comprises a No. 3 mold 4, a No. 2 mold 5 and a No. 1 mold 6;

[0029] A vibration fixing block 3 is fixedly installed on the outside of the casting outer column 2, and the vibration fixing block 3 is connected to a fluid vibration component, which includes a sliding rod 13, a motor 14, a rotating disk 19 and a vibration spring 26. The outsides of the No. 3 mold 4, the No. 2 mold 5 and the No. 1 mold 6 are all provided with a No. 3 sliding groove 21, and the No. 3 sliding groove 21 can overlap with the sliding protrusion 11. The outside of the No. 1 mold 6 is provided with a No. 1 pouring hole 7, the outsides of the No. 3 mold 4 and the No. 2 mold 5 are both provided with a No. 1 groove mold 9, and the outsides of the No. 3 mold 4 and the No. 2 mold 5 are both provided with a No. 2 pouring hole 8;

[0030] The outside of mold No. 2 5 and mold No. 1 6 are provided with a No. 2 groove mold 10. The motor 14 is fixedly installed on the outside of the vibration fixed block 3. The sliding rod 13 is rotatably connected to the motor 14. The rotating disk 19 is fixedly installed on the outside of the sliding rod 13. The vibration spring 26 is fixedly installed on the outside of the vibration fixed block 3. The end of the vibration spring 26 away from the vibration fixed block 3 is fixedly connected to the device base 1, and the device base 1 is rotatably connected to the vibration fixed block 3.

[0031] The working principle of a pouring device for a balanced weight casting based on the first embodiment is that when the pouring device for a balanced weight casting is needed for pouring and manufacturing, the third mold 4 is lowered along the inner wall of the casting outer column 2, because the third sliding groove 21 opened on the outside of the third mold 4 can overlap with the sliding protrusion 11 fixedly installed on the outside of the casting outer column 2, and finally the third mold 4, the second mold 5 and the first mold 6 can all slide along the sliding protrusion 11;

[0032] Finally, the No. 3 mold 4, the No. 2 mold 5 and the No. 1 mold 6 are slid to the bottom of the casting outer column 2 and fixedly connected. At the same time, the heating electromagnetic coil 16 is started to heat the mold. When the preparation work is completed, the liquid metal is poured along the No. 1 pouring hole 7 to pour it. Further, the liquid metal flows along the No. 1 pouring hole 7 to flow between the No. 3 mold 4, the No. 2 mold 5 and the No. 1 mold 6;

[0033] Heating the liquid metal can reduce its viscosity and make it more fluid. Lower viscosity helps the metal fill the entire mold cavity more quickly, improves pouring efficiency, and reduces possible poor filling, pores, and defects. Heating the liquid metal can increase its pouring temperature to approach or exceed its solidification temperature.

[0034] This helps reduce the cooling rate and avoids stress concentration and cracks caused by too fast solidification. Heating the liquid metal helps promote the discharge of gas from the metal. By increasing the temperature of the metal, the gas solubility is reduced, and bubbles will escape from the metal more easily, reducing the presence of pores and bubbles in the casting. Heating the liquid metal can improve its wettability, making it easier to contact the mold surface and fill the fine structure. This can improve the surface quality of the casting and reduce the generation of defects.

[0035] Embodiment 2

[0036] like Figure 1-6 As shown, a vibration protrusion 18 is fixedly installed on the outside of the rotating disk 19, and the number of the vibration protrusions 18 is multiple groups and distributed in a circular array. A vibration groove No. 1 12 is opened on the outside of the device base 1, and a vibration groove No. 2 20 is opened inside the vibration groove No. 1 12. The vibration groove No. 2 20 and the vibration protrusion 18 can overlap. A groove No. 4 17 is opened on the outside of the device base 1, and a fixed circle 24 is fixedly installed on the outside of the device base 1. An air outlet 25 is opened on the outside of the fixed circle 24;

[0037] A groove 22 for preventing adhesion is opened on the outside of the casting outer column 2, a casting hole 23 is opened on the outside of the casting outer column 2, and a No. 2 coil groove 15 is opened on the outside of the casting outer column 2. A heating electromagnetic coil 16 is fixedly installed on the inner wall of the No. 2 coil groove 15, and the shape of the heating electromagnetic coil 16 is a threaded shape.

[0038] Based on the first embodiment, when the liquid metal flows along the No. 1 pouring hole 7 to the No. 3 mold 4, the No. 2 mold 5 and the No. 1 mold 6, at the same time, the motor 14 is started to drive the sliding rod 13 to rotate. Since the sliding rod 13 is fixedly connected to the rotating disk 19, the rotation of the sliding rod 13 drives the rotating disk 19 to rotate. Since the vibration protrusion 18 is fixedly connected to the rotating disk 19, and the vibration protrusion 18 can overlap with the No. 2 vibration groove 20, the rotation of the rotating disk 19 drives the vibration protrusion 18 to rotate, and the vibration protrusion 18 and the No. 2 vibration groove 20 are continuously overlapped;

[0039] Finally, the sliding rod 13 vibrates under the elastic force of the vibration spring 26. Since the sliding rod 13 is movably connected to the vibration fixed block 3, the vibration of the sliding rod 13 drives the vibration fixed block 3 to vibrate. Since the vibration fixed block 3 is fixedly connected to the casting outer column 2, the vibration of the vibration fixed block 3 drives the casting outer column 2 to vibrate, and finally the device vibrates during the casting process.

[0040] Such a design in the present embodiment can be used for casting manufacturing using a casting device for a counterweight casting. Liquid metal with good fluidity can fill the entire casting cavity more quickly, ensuring that a complete structure is formed inside the casting and avoiding defects such as pores and cold shuts. Liquid metal with good fluidity can more easily expel bubbles and reduce the generation of pores, which is beneficial to improving the density and quality of the casting. Metal with good fluidity can fill the mold more evenly, which helps to reduce the temperature gradient inside the casting, thereby reducing the possibility of stress concentration and deformation. Liquid metal with good fluidity can wet the mold surface more evenly, which is beneficial to improving the surface finish and precision of the casting.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
