Description

Technical Field

[0001] This utility model relates to the field of cooling and forming technology, specifically to a rapid cooling and forming device for steam turbine castings. Background Technology

[0002] A steam turbine, also known as a steam turbine engine, is a rotary steam power unit. High-temperature, high-pressure steam passes through a fixed nozzle, becomes an accelerated airflow, and is then injected onto the blades, causing the rotor equipped with a row of blades to rotate and perform work.

[0003] Chinese utility model patent CN220005927U discloses an exhaust device for a casting mold, including a base. A lower mold and a gantry frame are fixedly connected to the bottom of the base. A cylinder is fixedly connected to the top of the gantry frame. An upper mold is fixedly connected to the output shaft of the cylinder. The upper mold is slidably fitted inside the lower mold. An exhaust assembly is provided between the upper mold and the gantry frame. This utility model has a reasonable structural design. Through the cooperation of an air pump, a telescopic pipe, and a filter head, air can be exhausted from the molding cavity formed between the upper and lower molds during the die-casting process, preventing air from reducing the quality of the casting. Through the cooperation of a drive motor, worm gear, worm wheel, bidirectional screw, moving plate, push-pull rod, lifting plate, vertical rod, and ejector plate, the formed casting can be ejected upwards after cooling and molding, making casting demolding more convenient and efficient.

[0004] To expel air from the molding cavity formed between the upper and lower molds, the aforementioned casting mold is equipped with an air extraction mechanism consisting of an air pump, a telescopic pipe, and a filter head. However, the casting mold does not have the function of filtering and purifying the air discharged by the air pump. If the molding cavity contains harmful substances, these substances will be discharged into the surrounding environment along with the air, causing pollution. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model discloses a rapid cooling and forming device for steam turbine castings, including a base 1, a lower mold 2 on the top of the base 1, an upper mold 3 movably disposed on the top of the lower mold 2, an air pump 4 above the upper mold 3, an air outlet pipe 403 fixedly disposed on one side of the air pump 4, a purification box 5 fixedly disposed at one end of the air outlet pipe 403, and a mounting base 6 movably disposed on the top of the purification box 5.

[0024] A connecting plate 601 is fixedly installed at the bottom of the mounting base 6. A ventilation opening 603 is provided inside the connecting plate 601. An activated carbon filter plate 602 is movably installed on one side of the connecting plate 601 by a first bolt 604. A threaded hole adapted to the first bolt 604 is provided inside the connecting plate 601. The mounting base 6 and the purification box 5 are movably connected by a second bolt 7. A storage box 8 is fixedly installed on one side of the base 1. A breathable mesh 801 is fixedly installed inside the storage box 8. A drying box 9 is movably installed inside the storage box 8. A desiccant pack 901 is provided inside the drying box 9.

[0025] Specifically, the lower mold 2 has an annular cavity 201 inside, a water inlet pipe 202 is fixedly installed on one side of the lower mold 2, and a water outlet pipe 203 is fixedly installed on the other side of the lower mold 2.

[0026] In this embodiment, an annular cavity 201, an inlet pipe 202, and an outlet pipe 203 are provided. Cold water is injected into the annular cavity 201 through the inlet pipe 202. The cold water absorbs heat as it flows within the annular cavity 201, thereby cooling the liquid metal and enabling it to cool and solidify rapidly. The cooled water, after absorbing heat and heating up, is then discharged from the outlet pipe 203.

[0027] Specifically, a cylinder 301 is fixedly installed on the top of the upper mold 3.

[0028] In this embodiment, by setting up a cylinder 301, the cylinder 301 pushes the upper mold 3 to move downward, so that the upper mold 3 and the lower mold 2 fit tightly together, thereby forming a closed cavity for casting between the upper mold 3 and the lower mold 2.

[0029] Specifically, a telescopic tube 401 is fixedly installed on one side of the air pump 4. One end of the telescopic tube 401 passes through the top of the upper mold 3 and extends into the interior of the upper mold 3. A filter head 402 is installed at one end of the telescopic tube 401.

[0030] In this embodiment, an air pump 4 is installed. The air pump 4 draws air out of the molding cavity through the telescopic tube 401, preventing air from remaining in the molding cavity and reducing the quality of the casting. When used in conjunction with a filter head 402, the filter head 402 blocks casting material from passing through, allowing only air to be extracted, effectively ensuring the venting effect.

[0031] Specifically, both the first bolt 604 and the second bolt 7 are made of stainless steel.

[0032] In this embodiment, by using stainless steel first bolt 604 and second bolt 7, the first bolt 604 and second bolt 7 are less prone to rusting.

[0033] Specifically, the storage box 8 has a door connected to the front hinge, and a door bolt is provided on one side of the door.

[0034] In this implementation plan, by setting up a cabinet door, the dust, moisture and other environmental factors can be effectively isolated after the cabinet door is closed, thus extending the tool's lifespan.

[0035] During use, the air in the molding cavity is drawn out through the telescopic tube 401 by the air pump 4. It works in conjunction with the filter head 402. The filter head 402 can block the casting material from passing through and only allow air to be drawn out. When the air pump 4 discharges the air in the molding cavity of the mold, the activated carbon filter plate 602 in the purification box 5 can filter and purify the discharged air, effectively adsorbing harmful substances in the air. Then the filtered and purified air will be discharged.

[0036] To disassemble the activated carbon filter plate 602, first loosen the first bolt 604 to release its restriction on the mounting base 6, then the activated carbon filter plate 602 can be pulled out of the purification box 5. Next, loosen the second bolt 7 to release its restriction on the activated carbon filter plate 602, then the activated carbon filter plate 602 can be removed and replaced.

[0037] In summary, this rapid cooling and molding device for steam turbine castings, by setting up a purification box 5 and an activated carbon filter plate 602, allows the activated carbon filter plate 602 in the purification box 5 to filter and purify the exhaust air when the air pump 4 discharges air from the mold molding cavity. This effectively adsorbs harmful substances in the air, preventing the air from the mold molding cavity from being directly discharged into the surrounding environment and causing environmental pollution, thus achieving the environmental protection goal. By setting up a first bolt 604 and a second bolt 7, first loosening the first bolt 604 releases its restriction on the mounting base 6, allowing the activated carbon filter plate 602 to be pulled out of the purification box 5. Then, loosening the second bolt 7 releases its restriction on the activated carbon filter plate 602, after which the activated carbon filter plate 602 can be disassembled, thus achieving its detachable function for replacement. By setting up a storage box 8 and a desiccant pack 901, tools used for device maintenance can be stored in the storage box 8 for later use. For example, tools for tightening bolts or other various tools can be placed there. Meanwhile, the desiccant pack 901 can maintain a dry environment inside the storage box 8, which is conducive to the proper storage of tools.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
