[0002] The continuous development of the manufacturing industry, particularly in precision casting fields such as marine valve covers, is moving towards greater efficiency and precision. In traditional casting processes, precise control of temperature, cleaning, and metal flow has always been key factors affecting casting quality and production efficiency. Current technologies rely primarily on manual operation and simple control systems, which cannot adequately guarantee the temperature stability of the molten metal during pouring, easily leading to defects such as uneven casting surfaces and uneven cooling. With the introduction of automation and intelligent technologies, casting equipment is moving towards integration and high precision, especially in the production of high-requirement castings such as marine valve covers, where increasingly refined management of each stage of the casting process is emphasized.

[0003] Most existing casting equipment introduces molten metal into the mold through a basic gating system (CN118682081A). However, these systems often rely on traditional pouring methods and lack precise control over the flow of molten metal.

The horizontal electric rail, through its drive connection with the first module, enables the mold to move precisely in the horizontal direction.

The connection between the circulating pump and the temperature control tube ensures continuous circulation of the heating medium through the temperature control tube, maintaining stable temperature control. The connection between the temperature control tube and the heating chamber guarantees the continuity and efficiency of the heating process, while ensuring rapid circulation of the heating medium, thus achieving precise control of the temperature of the molten metal or mold during the casting process. Through this structural design, the temperature control component can provide efficient temperature regulation during the casting process, ensuring a stable temperature of the molten metal, while effectively avoiding overheating or uneven cooling, improving the quality of castings and production efficiency.

The heating solenoid tube provides a continuous and stable heat source for the molten metal, preventing the metal from cooling too rapidly during flow, thus maintaining its molten state and ensuring smooth metal flow. The molten metal in the sprue, cross runner, and side runner is conducted heat from the heating solenoid tube, preventing solidification or uneven cooling during pouring. The connection of the sealing block to these runners and the melting tank also helps ensure that the heat from the heating solenoid tube is accurately transferred to the key parts of the gating system, optimizing metal flow control. In this way, the design of the heating solenoid tube ensures that the molten metal maintains an ideal temperature throughout the pouring process, thereby improving casting quality and reducing the impact of temperature fluctuations on the casting process.

A tight connection with the mold mechanism ensures mold stability and precision, thereby optimizing the casting process and reducing casting defects. Furthermore, the cleaning mechanism, through the collaboration of a vacuum pump and pump tubing, effectively cleans impurities from the mold and gating system, guaranteeing casting quality. The temperature control system, through the surrounding design of heating solenoids, ensures continuous heating of the molten metal in the gating system. The heating solenoids, surrounding the sprue, cross runner, sealing block, side runner, and melting tank, evenly transfer heat, preventing a sharp drop in metal temperature during flow and ensuring smooth metal flow.

The temperature control component 41, through its tight connection with the second module 34, provides a cooling function, effectively controlling temperature changes in the mold during the casting process, preventing overheating or uneven cooling, and ensuring the quality of the casting. The tight connection between the heating solenoid tube 42 and the melting tank 111 allows the heating system to provide uniform and stable heating around the melting tank 111, thereby maintaining the high temperature of the molten metal and avoiding temperature fluctuations during the pouring process. Through this design, the temperature control mechanism 4 can ensure precise temperature control of the mold and the molten metal, thereby optimizing the metal flow and cooling process during casting, improving the precision and quality of the casting, and reducing the occurrence of casting defects.

[0057] Furthermore, the temperature control component 41 includes a heating chamber 411, a cooling chamber 412, a circulating pump 413, and a temperature control tube 414. The heating chamber 411 and the cooling chamber 412 are connected, the heating chamber 411 and the circulating pump 413 are connected, the circulating pump 413 and the temperature control tube 414 are connected, and the temperature control tube 414 and the heating chamber 411 are connected.

[0058] By adopting the above technical solution, the interconnected design of the heating chamber 411 and the cooling chamber 412 enables heat exchange between them, thereby precisely regulating temperature changes in the temperature control system. The connection between the heating chamber 411 and the circulating pump 413 allows the heating system to deliver the heating medium to the temperature control tube 414 via the circulating pump 413, effectively transferring heat and ensuring the uniformity of the heating process. The connection between the circulating pump 413 and the temperature control tube 414 ensures continuous circulation of the heating medium through the temperature control tube 414, maintaining stable temperature control. The connection between the temperature control tube 414 and the heating chamber 411 ensures the continuity and efficiency of the heating process, while ensuring rapid circulation of the heating medium, thereby achieving precise control of the temperature of the molten metal or mold during the casting process. Through this structural design, the temperature control component 41 can provide efficient temperature regulation during the casting process, ensuring a stable temperature of the molten metal, while effectively avoiding overheating or uneven cooling, improving the quality of castings and production efficiency.

[0059] Furthermore, the heating solenoid tube 42 surrounds the sprue 114, the cross runner 115, the sealing block 116, the side runner 117, and the melting box 111.

[0060] By employing the above technical solution, the magnetic tube, designed to surround these key components, can uniformly heat the gating system through which the molten metal flows. The heating electromagnetic tube 42 provides a continuous and stable heat source for the molten metal, preventing the metal from cooling too quickly during flow, thus maintaining its molten state and ensuring smooth metal flow. The molten metal in the sprue 114, cross runner 115, and side runner 117 is conducted heat from the heating electromagnetic tube 42, preventing solidification or uneven cooling during pouring. The connection of the sealing block 116 to these runners and the melting tank 111 also helps ensure that the heat from the heating electromagnetic tube 42 is accurately transferred to the key parts of the gating system, optimizing metal flow control. In this way, the design of the heating electromagnetic tube 42 ensures that the molten metal maintains an ideal temperature throughout the pouring process, thereby improving the quality of the casting and reducing the impact of temperature fluctuations on the casting process.

[0061] Working principle of the invention:

[0062] The casting mechanism 1 consists of a melting tank 111, a casting tank 112, a pouring cup 113, a sprue 114, a cross runner 115, a sealing block 116, and a side runner 117. The precise design of the gating system and the opening and closing action of the sealing block 116 ensure that the molten metal enters the mold stably and accurately, avoiding fluctuations or leakage during the metal flow process. Through a tight connection with the mold mechanism 3, the stability and precision of the mold are ensured, thereby optimizing the casting process and reducing casting defects. Furthermore, the cleaning mechanism 2, through the cooperation of the vacuum pump 21 and pump pipe 22, effectively cleans impurities from the mold and gating system, ensuring the quality of the castings. The temperature control system, through the surrounding design of the heating solenoid tube 42, ensures continuous heating of the molten metal in the gating system. The heating solenoid tube 42 surrounds the sprue 114, cross runner 115, sealing block 116, side runner 117, and melting tank 111, enabling uniform heat transfer and preventing a sharp drop in metal temperature during flow, ensuring smooth metal flow. The heating chamber 411, cooling chamber 412, circulating pump 413, and temperature control tube 414 in the temperature control assembly 41 work together to precisely regulate the temperature of the molten metal and the mold, avoiding the impact of temperature fluctuations on casting quality. This system can adjust temperature changes in real time, ensuring the stability of the casting process and preventing overcooling or overheating. It ensures that the molten metal maintains an ideal temperature throughout the casting process and precisely controls the speed and distribution of metal flowing into the mold, optimizing the casting process. The efficient operation of the cleaning mechanism further guarantees the surface quality of the castings, extends the service life of the equipment, and enables the casting unit to improve production efficiency and reduce material waste.
