Technical Field
[0001] This utility model relates to the field of casting technology, specifically to a casting device for malleable cast iron parts. Background Technology
[0002] Malleable cast iron is cast iron made by casting molten iron with a certain chemical composition into white cast iron billets and then annealing them. It has high strength, plasticity and impact toughness and can partially replace carbon steel. Compared with gray cast iron, malleable cast iron has better strength and plasticity, especially better low-temperature impact performance. Its wear resistance and vibration damping properties are better than ordinary carbon steel. Because of its certain plasticity and toughness, this type of cast iron is commonly known as malleable iron or malleable cast iron. It is also called malleable cast iron or tough cast iron. Blackheart malleable cast iron is used for parts subjected to impact, vibration and torsional loads. It is often used to manufacture automobile rear axles, spring brackets, low-pressure valves, pipe fittings, tool wrenches, etc. The production of malleable cast iron parts requires a casting process and the use of professional casting equipment.
[0003] Existing casting equipment has a simple structure and single function, and cannot quickly cool down the malleable cast iron parts after casting. Generally, cooling water is injected, but because the malleable cast iron parts are attached tightly to the casting chamber, the cooling water cannot flow quickly to the bottom of the casting chamber for cooling, which greatly reduces the overall cooling efficiency and effect. At the same time, when the casting equipment is large, it is very difficult to open the top of the casting for material discharge, making the whole casting process time-consuming and laborious. Utility Model Content
[0004] The purpose of this utility model is to provide a casting device for malleable cast iron parts, so as to solve the problems mentioned in the background art. The existing casting devices have simple structures and single functions, and cannot quickly cool down the malleable cast iron parts after casting. Generally, cooling water is injected, but because the malleable cast iron parts are attached tightly to the casting chamber, the cooling water cannot flow quickly to the bottom of the casting chamber for cooling, which greatly reduces the overall cooling efficiency and effect. At the same time, when the casting device is large in size, the process of opening the top of the casting and discharging the material is very difficult, resulting in the time-consuming and laborious overall casting process.

Both the water inlet and the drain outlet are provided with sealing caps, and an observation window is provided on one side surface of the cooling box.
[0008] Preferably, the bottom of the casting base is provided with support legs on both sides, and the bottom end of each support leg is provided with a positioning suction cup.
[0009] Preferably, the top end of the lifting screw is provided with a rotating disk, and the outer edge of the top of the rotating disk is provided with a rotating handle.
[0010] Preferably, an electric push rod is provided at the bottom of the casting chamber, and a discharge plate is provided at the top of the electric push rod.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This malleable cast iron casting device, during daily use, after casting, can pump cooling water from inside the cooling tank into the cooling chamber by starting the delivery pump. The cooling water inside the cooling chamber makes rapid and comprehensive contact with the bottom and sides of the casting chamber, achieving rapid cooling of the malleable cast iron after casting, replacing the traditional cooling method, and making the cooling more efficient and effective.
[0013] This malleable cast iron casting device, during daily use, when a large volume of casting material needs to be discharged, can be rotated by twisting the lifting screw. The screw thread drives the lifting block to move upward, which in turn opens the cover on top of the casting device. The motor drives the rotating rod and rotating block to rotate inside the rotating groove, thus flipping the cover on top of the casting device so that it is perpendicular to the discharge port at the top of the casting device. This allows for rapid material discharge, saving manpower and resources in the process. Attached Figure Description

[0018] 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.
[0019] Please see Figure 1-3This utility model provides a technical solution: a casting device for malleable cast iron parts, including a casting base 12, a casting chamber 22 disposed on the inner side of the casting base 12, a cooling chamber 21 disposed on the outer side of the casting chamber 22, a cooling box 7 disposed on one side surface of the casting base 12, and a delivery pump 3 disposed on the top of the cooling box 7. By starting the delivery pump 3, cooling water inside the cooling box 7 is pumped into and delivered to the cooling chamber 21, and the cooling water inside the cooling chamber 21 rapidly interacts with the bottom and sides of the casting chamber 22. The rapid and comprehensive contact enables quick cooling of malleable cast iron parts after forming, replacing traditional cooling methods and resulting in higher cooling efficiency and better performance. A casting cover 1 is provided on the top of the casting base 12, and a casting port 18 is provided on the top of the casting cover 1. The material is introduced into the casting chamber 22 through the casting port 18 for forming. A pad 10 is provided on one side of the bottom of the casting base 12. A lifting screw 13 is rotatably mounted on the top of the pad 10 via a bearing 11. The surface of the lifting screw 13 is movable. A lifting screw block 14 is fitted onto the casting device. A rotating groove 26 is formed on one side of the lifting screw block 14. A rotating block 25 is rotatably mounted inside the rotating groove 26. A rotating rod 15 is installed inside the rotating block 25, penetrating the rotating groove 26. A motor 23 is installed at one end of the rotating rod 15. When a large volume of material needs to be discharged from the casting device, the lifting screw 13 can be rotated by twisting it. The screw 13 drives the lifting screw block 14 to move upwards through threaded engagement, thereby causing the top cover of the casting device to open. When the motor 23 drives the rotating rod 15 and the rotating block 25 to rotate inside the rotating groove 26, the cover at the top of the casting device is flipped over and is perpendicular to the discharge port at the top of the casting device. The inlet and outlet of the conveying pump 3 are connected to the cooling box 7 and the cooling chamber 21 through the pipe 2, respectively. A support plate 24 is provided on one side of the bottom lifting screw block 14 of the motor 23, which can support and limit the motor 23 and prevent the motor 23 from being suspended and unable to operate normally.
[0020] A water inlet 4 is located near the top of one side of the cooling tank 7, allowing for real-time replenishment and addition of cooling water to prevent insufficient cooling water volume. A drain outlet 27 is located at the bottom of the casting base 12, allowing cooling water from the subsequent cooling chamber 21 to be discharged. Both the water inlet 4 and the drain outlet 27 are fitted with sealing caps 5. An observation window 6 is located on one side of the cooling tank 7, allowing for real-time monitoring of the cooling water volume to prevent insufficient cooling water from affecting the cooling effect. Support legs 9 are located on both sides of the bottom of the casting base 12, and each support leg 9 has a positioning suction cup 8 at its bottom end to increase the overall stability of the device with the ground. The adsorption capacity enhances the overall stability and firmness of the casting. The top of the lifting screw 13 is equipped with a rotating disk 16, and the outer edge of the top of the rotating disk 16 is equipped with a rotating handle 17, which can be easily rotated by manually holding the rotating handle 17 to make the lifting height adjustment operation more labor-saving. The bottom of the casting chamber 22 is equipped with an electric push rod 20, and the top of the electric push rod 20 is equipped with a discharge plate 19. The discharge plate 19 can be raised by the electric push rod 20 to push out the formed malleable cast iron parts for discharge, avoiding damage caused by forcibly discharging the malleable cast iron parts that are tightly attached to the casting chamber 22.
[0021] Working Principle: When casting malleable cast iron parts is required, the raw materials to be cast are first introduced into the casting chamber 22 through the casting port 18. The casting chamber 22 then forms the casting. After casting, the cooling water inside the cooling tank 7 is pumped into the cooling chamber 21 by the pump 3. The cooling water in the cooling chamber 21 makes rapid and comprehensive contact with the bottom and sides of the casting chamber 22, achieving rapid cooling of the malleable cast iron parts after forming. This replaces traditional cooling methods, resulting in higher cooling efficiency and better performance. When discharging material from a large-volume casting device, the lifting screw 13 can be rotated by twisting it. The screw 13 drives the lifting block 14 to move upward, which in turn opens the cover at the top of the casting device. The motor 23 drives the rotating rod 15 and the rotating block 25 to rotate inside the rotating groove 26, thus flipping the cover at the top of the casting device so that it is perpendicular to the discharge port at the top of the casting device. Finally, the electric push rod 20 drives the discharge plate 19 to rise, ejecting the formed malleable cast iron part for discharge.
[0022] 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.
