Description

Technical Field

[0001] This utility model relates to the field of stainless steel casting forming technology, and in particular to a stainless steel casting forming equipment with rapid cooling function. Background Technology

[0002] Stainless steel casting refers to the process of melting stainless steel material and pouring it into a pre-made mold using casting technology, followed by cooling and solidification to obtain stainless steel parts with specific shapes and dimensions. This process includes melting, pouring, cooling, demolding, and subsequent processing. Stainless steel possesses excellent corrosion resistance, high strength, and good machinability, making it suitable for harsh environments such as high temperature, high pressure, and strong corrosion. Common stainless steel casting methods include sand casting, precision casting, and investment casting. Stainless steel castings are widely used in petrochemical, shipbuilding, machinery, nuclear power, and medical fields, enabling the integral molding of complex structural parts and effectively improving the strength and service life of components.

[0003] In the machining of stainless steel and other metal castings, specialized casting molds are essential for rapid prototyping to meet high precision and performance requirements. While existing technologies utilize specialized casting molds for rapid prototyping, the external water jackets or cooling holes of these molds have significant limitations in practical applications. Firstly, the indirect contact between the cooling medium and the liquid metal leads to low heat transfer efficiency. Secondly, the lengthy and uneven heat transfer paths result in slow cooling and an uneven temperature field, causing problems such as coarse internal structure and performance fluctuations in the casting. This makes it difficult to guarantee the molding accuracy of the mold and the stability of the casting's mechanical properties, extending the casting cycle, reducing production efficiency, and limiting the potential application of castings in high-end industrial products.

[0004] Therefore, there is an urgent need for a new type of rapid cooling forming equipment that can achieve efficient and uniform heat conduction between the casting and the cooling system, thereby improving production efficiency, reducing energy consumption, and ensuring the fineness of the microstructure and uniformity of the casting to meet the stringent quality requirements of modern industry. Based on this, we propose a stainless steel casting forming equipment with rapid cooling function. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a stainless steel casting molding equipment with rapid cooling function, which can solve the problems of slow cooling speed, coarse internal structure, fluctuating mechanical properties and low production efficiency caused by the indirect contact between the cooling medium and molten metal in the existing mold, the long heat conduction path and uneven temperature field distribution.

[0007] To solve the above-mentioned technical problems, this utility model provides a stainless steel casting forming equipment with rapid cooling function, which adopts the following technical solution: it includes a casting mold, and a cooling support assembly is provided at the bottom of the casting mold. The cooling support assembly includes a heat insulation base, and a circulation conveying component is provided at the bottom of one side of the heat insulation base. The circulation conveying component includes an input pump box, and the circulation conveying component is installed at the bottom of one side of the heat insulation base. An output pump box is provided on the side of the heat insulation base away from the input pump box.

[0008] Optionally, the top of the heat insulation base is provided with an installation slot, and the interior of the heat insulation base is provided with a rapid cooling cavity.

[0009] Optionally, the rapid cooling cavity is provided with circulating cooling pipes, the two ends of which are respectively connected to the input pump box and the output pump box. A rapid heat conduction component is also provided on the side of the rapid cooling cavity near the circulating cooling pipes.

[0010] Optionally, the rapid heat conduction component includes a metal heat conduction plate disposed inside the rapid cooling cavity. The metal heat conduction plate is in contact with the circulating cooling pipe. A metal heat conduction strip is also connected to one side of the metal heat conduction plate and is installed inside the mounting slot.

[0011] Optionally, the metal heat-conducting plate and the metal heat-conducting strip are both made of copper-silver alloy material.

[0012] Optionally, the casting mold is matched with the mounting slot structure, the top of the casting mold is provided with several sets of casting forming grooves, and the bottom of the casting mold is provided with several sets of embedded grooves around its perimeter. The embedded grooves are matched with the metal heat-conducting strip structure, and the embedded grooves and the metal heat-conducting strip are engaged by a snap-fit.

[0013] In summary, this utility model has at least one of the following beneficial effects:

[0014] 1. The stainless steel casting forming equipment designed in this scheme, through the setting of cooling support components, includes a rapid cooling cavity in the heat-insulated base with circulating cooling pipes, and together with the input pump box and output pump box to form a circulating conveying system, can efficiently circulate and deliver the external ultra-low temperature cooling medium into the pipeline, achieving continuous and rapid cooling of the bottom of the casting mold. At the same time, by utilizing the contact fit structure of the metal heat-conducting plate and metal heat-conducting strip, and the embedded groove design around the bottom of the casting mold that matches the metal heat-conducting strip, the ultra-low temperature can be uniformly conducted to the casting mold, optimizing the casting cooling process. When the ultra-high temperature stainless steel molten liquid is injected into the mold forming tank, the equipment can continuously perform low-temperature cooling treatment on the mold through the synergistic action of various components, which can quickly reduce the temperature of the stainless steel molten liquid, achieve rapid cooling and forming within the mold, effectively improve production efficiency, and shorten the casting cycle.

[0015] 2. The stainless steel casting forming equipment designed in this scheme, by evenly distributing multiple sets of metal heat-conducting strips on the inner side of the mounting slot, and in conjunction with the snap-fit ​​structure of the embedded groove and the metal heat-conducting strips, can ensure that the temperature of the ultra-low temperature cooling medium is evenly distributed on the casting mold. During the cooling process, the metal heat-conducting components rapidly conduct the temperature of the cooling medium to all parts of the mold, making the casting cool evenly and avoiding problems such as coarse internal structure and performance fluctuations caused by local cooling rate differences. As can be seen from the above structure, this casting forming equipment can achieve continuous and stable cooling of the mold while ensuring high-capacity continuous casting, reducing energy consumption, reducing shrinkage cavities and crack defects, and meeting the strict requirements of high-end industries for high precision and high performance of stainless steel castings.

[0023] 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.

[0024] Example: Refer to Figures 1 to 5 This utility model provides an embodiment of a stainless steel casting forming device with rapid cooling function, including a casting mold 1. A cooling support assembly 2 is provided at the bottom of the casting mold 1. The cooling support assembly 2 includes a heat-insulating base 3. A circulating conveying component 4 is provided on one side of the bottom of the heat-insulating base 3. The circulating conveying component 4 includes an input pump box 5. The circulating conveying component 4 is installed on one side of the bottom of the heat-insulating base 3. An output pump box 6 is provided on the side of the heat-insulating base 3 away from the input pump box 5. When ultra-high temperature molten stainless steel is injected into the casting forming groove 13 opened at the top of the casting mold 1, through the coordinated use of the input pump box 5, the output pump box 6, the circulating cooling pipe 9, the metal heat-conducting plate 11, and the metal heat-conducting strip 12, the casting mold 1 can continuously perform low-temperature cooling treatment, rapidly cooling the ultra-high temperature in the molten stainless steel, allowing it to rapidly cool and form inside the casting mold 1. The top of the heat-insulating base 3... The part has an installation slot 7, and the heat insulation base 3 has a rapid cooling cavity 8 inside. The rapid cooling cavity 8 inside the heat insulation base 3 can provide installation space for the circulating cooling pipe 9 and the rapid heat conduction component 10, ensuring that the cooling medium can circulate efficiently and conduct heat quickly, so as to achieve uniform cooling of the casting mold 1. The rapid cooling cavity 8 has a circulating cooling pipe 9 distributed inside. The two ends of the circulating cooling pipe 9 are respectively connected to the input pump box 5 and the output pump box 6. The rapid heat conduction component 10 is also provided on the side of the rapid cooling cavity 8 near the circulating cooling pipe 9. By installing the circulating cooling pipe 9 inside the rapid cooling cavity 8, and the two ends of the circulating cooling pipe 9 are connected to the input pump box 5 and the output pump box 6, a complete cooling medium circulation system can be formed, so that the ultra-low temperature cooling medium can continuously flow through the circulating cooling pipe 9, thereby achieving effective cooling of the inside of the rapid cooling cavity 8.

[0025] The rapid heat conduction component 10 includes a metal heat conduction plate 11, which is disposed inside the rapid cooling cavity 8. The metal heat conduction plate 11 is in contact with the circulating cooling pipe 9. A metal heat conduction strip 12 is also connected to one side of the metal heat conduction plate 11 and is installed inside the mounting slot 7. Through the structural design of the contact fit between the metal heat conduction plate 11 and the circulating cooling pipe 9, the ultra-low temperature in the circulating cooling pipe 9 can be efficiently conducted to the surface of the metal heat conduction plate 11, achieving rapid heat transfer. Both the metal heat conduction plate 11 and the metal heat conduction strip 12 are made of copper-silver alloy. The high thermal conductivity and good heat transfer performance of copper-silver alloy can be utilized to achieve rapid and efficient heat transfer of the circulating cooling pipe 9. The ultra-low temperature in the cooling pipe 9 is conducted to the casting mold 1, ensuring that the casting can be cooled evenly and quickly during the cooling process. The casting mold 1 is structurally matched with the mounting slot 7. Several sets of casting forming grooves 13 are opened on the top of the casting mold 1, and several sets of embedded grooves 14 are also opened around the bottom of the casting mold 1. The embedded grooves 14 are structurally matched with the metal heat-conducting strips 12. The embedded grooves 14 and the metal heat-conducting strips 12 are engaged. Through the structural design of the engagement between the embedded grooves 14 and the metal heat-conducting strips 12, the casting mold 1 can be stably positioned and placed inside the heat insulation base 3. At the same time, it is conducive to efficient heat conduction between the metal heat-conducting strips 12 and the casting mold 1, realizing rapid and uniform cooling of the casting mold 1, and improving the forming quality and performance stability of the casting.

[0026] Working Principle: The stainless steel casting forming equipment designed in this scheme mainly consists of a casting mold 1 and a cooling support assembly 2. The cooling support assembly 2 includes a heat-insulating base 3 and a circulating conveying component 4. The heat-insulating base 3 has an internal mounting slot 7 and a rapid cooling cavity 8. The rapid cooling cavity 8 contains circulating cooling pipes 9 and is equipped with a rapid heat-conducting component 10. The rapid heat-conducting component 10 includes a metal heat-conducting plate 11 and a metal heat-conducting strip 12, both of which are in contact with each other. When the input pump box 5 and the output pump box 6 in the circulating conveying component 4 are powered on, since the two ends of the circulating cooling pipe 9 are connected to the input pump box 5 and the output pump box 6 respectively, the external ultra-low temperature cooling medium can be circulated and transported into the circulating cooling pipe 9. Because the circulating cooling pipe 9 is in contact with the metal heat-conducting plate 11, and the metal heat-conducting plate 11 is in contact with the metal heat-conducting plate 12, the circulating cooling medium can be circulated and transported into the circulating cooling pipe 9. The heat-conducting plate 11 and the metal heat-conducting strip 12 are in contact and cooperate. The ultra-low temperature cooling medium circulating inside can conduct ultra-low temperature to the surface of the metal heat-conducting strip 12. At the same time, multiple sets of embedded grooves 14 are opened around the bottom of the casting mold 1. They are matched with the structure of the metal heat-conducting strip 12 and are snap-fitted. Through the multiple sets of metal heat-conducting strips 12 evenly distributed inside the mounting slot 7, the ultra-low temperature cooling temperature can be evenly distributed on the casting mold 1. When the ultra-high temperature stainless steel melt is injected into the casting forming groove 13 opened at the top of the casting mold 1, the casting mold 1 can continuously perform low temperature cooling treatment by means of the cooperation between the input pump box 5, the output pump box 6, the circulating cooling pipe 9, the metal heat-conducting plate 11, and the metal heat-conducting strip 12, which can quickly reduce the temperature of the stainless steel melt and make it cool and form quickly inside the casting mold 1.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
