Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an aluminum ingot melting mold. Background Technique

[0002] The aluminum ingot melting mold is a key component in the aluminum ingot casting process. Its design and performance directly affect the quality and production efficiency of aluminum ingots. Aluminum ingot melting molds are usually made of materials with good thermal conductivity, wear resistance, heat resistance, and certain mechanical strength. Common materials include: cast iron, especially ductile iron. Due to its excellent thermal fatigue resistance and mechanical properties, it has become an ideal choice for manufacturing aluminum ingot molds. Ductile iron has a longer service life and better wear resistance compared to ordinary gray cast iron. In summary, the aluminum ingot melting mold is an indispensable key component in the aluminum ingot casting process. By selecting appropriate materials, optimizing the structural design, improving the mold performance, and regularly maintaining and servicing, etc., the normal use of the aluminum ingot melting mold can be ensured and its service life can be extended, thereby improving the production efficiency and quality of aluminum ingots.

[0003] In the core link of the aluminum ingot casting process, the mold plays a crucial role. Its performance directly affects the finished product quality of aluminum ingots and the overall production efficiency. For a long time, the industry has generally used cast iron, especially ordinary gray cast iron, as the main material for aluminum ingot molds. However, although this traditional choice has its cost - effectiveness, it faces significant limitations: the service life of the mold is generally relatively short, often only reaching a few months, far from meeting the urgent needs of modern industry for high - efficiency and continuous production. More seriously, during the aluminum ingot demolding process, the mold needs to bear a huge external force impact from the aluminum ingot. This high - frequency and high - intensity impact cycle, like countless tiny "earthquakes", continuously erodes the structural integrity of the mold, accelerating the wear and failure process of the mold. In the long run, it not only increases the mold replacement frequency and production cost, but also poses a potential threat to the stability of aluminum ingot production and product quality.

[0004] The purpose of the utility model is to solve the problem that when the above - mentioned equipment is in use, due to the inability to meet the efficient separation of oil - gas mixtures, it is easy to cause air quality pollution and affect human respiratory health, and to propose an aluminum ingot melting mold.

[0005] To achieve the above - mentioned purpose, the utility model adopts the following technical scheme: An aluminum ingot melting mold, including a bottom mold mechanism, and an adjusting mechanism is fixedly connected to the outer surface wall of the bottom mold mechanism;

[0006] The bottom die mechanism includes a lower die, a set of punch dies are arranged on the top of the lower die, an internal cooling groove is opened inside the lower die, temperature guiding inner plates are fixedly connected to the inner walls of a set of the punch dies, a set of limiting rods are fixedly installed on the top of the lower die, and two cooling shunt pipes are fixedly communicated with the outer wall of the lower die.

[0007] Preferably, outer connecting pipes are fixedly communicated with one sides of the outer walls of the two cooling shunt pipes.

[0008] Preferably, the adjusting mechanism includes two side mounting plates, and sliding grooves are preset inside the two side mounting plates.

[0009] Preferably, sliders are slidably embedded in the inner walls of the two groups of sliding grooves, adjusting plates are fixedly connected to the outer walls of the two groups of sliders, and linkage plates are fixedly installed on one sides of the outer walls of the two adjusting plates.

[0024] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0025] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0026] Embodiment 1, as Figures 1-4 shown, an aluminum ingot melting mold of the present utility model includes a bottom mold mechanism 1, and an adjustment mechanism 2 is fixedly connected to the outer surface wall of the bottom mold mechanism 1;

[0027] The bottom mold mechanism 1 includes a lower mold 101, a set of punches 103 are arranged on the top of the lower mold 101, an inner cooling tank 102 is opened inside the lower mold 101, heat conduction inner plates 1031 are fixedly connected to the inner surface walls of the set of punches 103, a set of limit rods 104 are fixedly installed on the top of the lower mold 101, two cooling shunt pipes 105 are fixedly communicated with the outer surface wall of the lower mold 101, and outer connection pipes 106 are fixedly communicated with one side of the outer walls of the two cooling shunt pipes 105.

[0028] The effect achieved by the entire Embodiment 1 is as follows. First, when the device is in use, an internal cooling groove 102 is provided inside the lower die 101. Four heat-conducting inner plates 1031 are respectively fixedly connected between the inner walls of the punch 103. After the aluminum ingot is cooled by the device, the residual heat of the punch 103 itself can be absorbed by the heat-conducting inner plates 1031, and this heat can be effectively transferred to the inside of the internal cooling groove 102. Under the action of the two cooling shunt pipes 105, a one-in-one-out design of the gas is formed between the two. At the beginning of cooling, the cooling gas is maintained at room temperature, and then as time delays, the temperature of the cooling gas gradually decreases, so as to complete the temperature reduction treatment of the punch 103.

[0029] Embodiment 2 is as Figures 2-4 shown. The adjusting mechanism 2 includes two side mounting plates 201. Sliding grooves 202 are respectively preset inside the two side mounting plates 201. Sliders 203 are slidably embedded in the inner walls of the two groups of sliding grooves 202. Adjusting plates 204 are fixedly connected to the outer surfaces of the two groups of sliders 203. Linking plates 205 are fixedly installed on one side of the outer walls of the two adjusting plates 204. Cylinders 206 are fixedly connected to the bottoms of the two linking plates 205, and the bottoms of the two cylinders 206 are respectively fixedly connected to one side of the outer walls of the two side mounting plates 201. An upper die 207 is fixedly installed between one side of the outer walls of the two adjusting plates 204. A group of limiting grooves 208 are opened at the bottom of the upper die 207. A diversion groove 209 is opened at the bottom of the upper die 207. The outer surfaces of a group of limiting rods 104 are movably inserted into the inside of the group of limiting grooves 208. The outer wall between one side of the two side mounting plates 201 is fixedly connected to the outer surface of the lower die 101.

[0030] The effect achieved by the entire Embodiment 2 is as follows. Before forming, under the action of the two cylinders 206, they respectively generate elasticity, and driven by the two linking plates 205, the adjusting plates 204 can be maintained to move up and down (under the cooperation that the sliders 203 are respectively slidably embedded in the sliding grooves 202), so that the upper die 207 between the two adjusting plates 204 moves downward, so as to keep the upper die 207 and the lower die 101 in a combined state. Then, through the holes opened at the top of the upper die 207, the molten aluminum ingot melt is passed through the internal channel of the upper die 207 and respectively transferred to the cavity between the two through the diversion groove 209, so as to carry out the cooling and forming treatment.

[0031] Working principle: In the forming preparation stage, two cylinders 206 are driven simultaneously, demonstrating telescopic capabilities. This action, in coordination with the linkage plate 205, ensures that the adjusting plate 204 can slide smoothly along the slider 203 within the sliding groove 202 to achieve vertical adjustment. This process prompts the upper mold 207 between the two adjusting plates 204 to move precisely downward until it fits tightly with the lower mold 101, forming a closed mold space. Subsequently, using the holes preset at the top of the upper mold 207, the molten aluminum ingot melt is injected into its internal channels and evenly distributed through the diversion groove 209 into the cavity formed between the upper and lower molds 101. In this cavity, the aluminum melt gradually cools and solidifies. To accelerate the cooling process, the upper mold 207 and the lower mold 101 are made of ductile iron, and an internal cooling groove 102 is ingeniously designed inside the lower mold 101. This groove is closely connected to the inner wall of the punch 103 through four evenly distributed heat-conducting inner plates 1031. This structural arrangement enables the residual heat accumulated on the punch 103 to be effectively absorbed and transferred to the internal cooling groove 102 during the cooling process of the aluminum ingot. Further, the cooling system realizes the cyclic flow of cooling gas through two cooling shunt pipes 105, forming an efficient heat exchange mode of one-in and one-out. In the initial stage, the cooling gas remains at room temperature. As time goes by and the cooling demand increases, the gas temperature gradually decreases, thereby achieving continuous and effective cooling of the punch 103 and ensuring the quality and efficiency of aluminum ingot forming.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still fall within the protection scope of the technical solution of the present invention.
