Description

Technical Field

[0001] This utility model relates to the technical field of temperature control equipment for hardware castings, and in particular to a high-performance temperature control device for hardware castings. Background Technology

[0002] In the field of metal casting, the performance of temperature control equipment plays a decisive role in the quality and production efficiency of metal castings.

[0003] Currently, traditional temperature control equipment for metal castings mostly uses PID control technology to regulate temperature, achieving temperature control through resistance heating and cooling water circulation systems. However, in actual metal casting processes, the melting process exhibits nonlinear and time-varying characteristics, making it difficult for traditional PID control to accurately track and adjust the temperature in real time. This results in insufficient temperature control precision, affecting the quality of the metal castings. Furthermore, the resistance heating and cooling water circulation systems suffer from low energy conversion efficiency during operation, with significant energy wasted during transmission and conversion, leading to excessive energy consumption and increased production costs for enterprises. In particular, excessive energy consumption not only imposes a heavy economic burden on enterprises but also contradicts the current development concepts of green environmental protection and energy conservation. Therefore, improving the energy utilization rate of temperature control equipment and reducing energy consumption while ensuring temperature control precision has become a crucial issue that urgently needs to be addressed in the field of temperature control equipment for metal castings. Thus, improvements are needed to address these issues. Utility Model Content

[0020] In this invention, a cover plate 2 with a vacuum layer is installed on the upper end of the outer shell 1, which facilitates the maintenance of the internal temperature of the casting furnace 12. The cover plate 2 is convex, and an electromagnetic shielding layer is coated on the bottom end of the cover plate 2. A feed inlet 3 is opened at the upper end of the cover plate 2, which facilitates the entry of materials into the casting furnace 12. A stepper motor 4 is installed in the middle of the top surface of the cover plate 2, which facilitates the provision of driving force to the stirring plate 11. The output shaft of the stepper motor 4 is rotatably connected to the cover plate 2 through a sealed bearing, and the end of the output shaft of the stepper motor 4 is fixedly connected to the stirring plate 11, which facilitates the uniform heating of materials in the casting furnace 12. A thermocouple is installed at one end of the stepper motor 4. 5. The thermocouple 5 facilitates the real-time temperature detection inside the casting furnace 12. The thermocouple 5 is of type K. The thermocouple 5 penetrates the cover plate 2, and its end is located outside the stirring plate 11. The casting furnace 12 is installed inside the outer shell 1, which facilitates the melting and preservation of materials. The inner cavity of the casting furnace 12 has a vacuum layer, and the outer side of the casting furnace 12 is wound with multiple turns of high-temperature wire 13. A cooling plate 14 is installed on the outer side of the casting furnace 12, which abuts against the inner side of the vacuum layer and penetrates one side of the vacuum layer.

The feed port 3 is closed and the rectifier 7 and oscillator 8 are started by the control panel 9. The high temperature wire 13 connected to the oscillator 8 generates electromagnetic induction at the casting furnace 12 through oscillation, which raises the temperature inside the casting furnace 12. When the raw material in the casting furnace 12 reaches the theoretical initial melting stage, the stepper motor 4 is started to drive the stirring plate 11 to rotate, which accelerates the melting of the raw material. When the thermocouple 5 detects that the temperature is higher than the process flow temperature, the fan 10 is started. The fan 10 blows cold air into the outer shell 1 and after passing through the cooling plate 14 installed at the outer end of the casting furnace 12, the excess heat is carried out from the circulation pipe 6.
