Description

Technical Field

[0001] The present invention relates to the technical field of electric furnaces for automobile mold castings, and particularly relates to an electric furnace for automobile mold production with heat recovery and utilization. Background Art

[0002] The production of automobile molds often requires precise process control, and electric furnace heating is a common processing step. During the manufacturing process of automobile molds, for example, operations such as the forming and heat treatment of mold materials, the stable high-temperature environment provided by the electric furnace is a key factor in ensuring the quality of the molds.

[0003] With the continuous increase in energy prices, automobile mold production enterprises are facing high energy costs. In the increasingly competitive market, reducing production costs, especially energy costs, has become an important means for enterprises to improve their competitiveness.

[0004] Traditional electric furnaces for automobile mold production generate a large amount of waste gas during the heating process. These waste gases are usually directly discharged into the environment, and the heat carried by the waste gases is not effectively utilized, resulting in energy waste. At the same time, when the traditional electric furnace is working, its heat dissipation mainly occurs through natural convection and radiation, without a special heat recovery device, which causes heat to be dissipated into the surrounding environment and increases the additional energy consumption. Summary of the Invention

[0005] The purpose of the present invention is to provide an electric furnace for automobile mold production with heat recovery and utilization to solve the above problems.

[0006] The present invention specifically adopts the following technical solutions to achieve the above purpose: An electric furnace for automobile mold production with heat recovery and utilization, comprising a bottom plate, a moving table, a gate assembly, and a furnace body. The gate assembly and the furnace body are installed on the upper surface of the bottom plate, and the gate assembly is located on the outer wall of the port of the furnace body. The moving table moves on the upper surface of the bottom plate. When the moving table moves into the interior of the furnace body, an inner cavity is formed between the moving table and the furnace body, and the gate assembly seals the inner cavity. A plurality of heating elements are installed on the inner wall of the furnace body, a water tank is installed on the top of the furnace body, and the waste gas inside the furnace body is used to heat the water tank. A plurality of drying components are respectively installed on both sides of the water tank for drying the steam. Heat conduction structures are respectively arranged on both sides of the furnace body, and a plurality of heat storage rods are arranged inside the moving table. Both ends of the heat storage rods are respectively close to the heat conduction structures on both sides of the furnace body. The purpose of the above settings is that initially, the mobile platform can move on the upper surface of the bottom plate. When machining automotive die castings is required, the mobile platform moves into the interior of the furnace body. At this time, the mobile platform and the furnace body form an inner cavity, and the gate assembly will seal this inner cavity to provide a relatively enclosed space for subsequent operations such as heating; A number of heating elements installed on the inner wall of the furnace body start to work to heat the automotive die casting in the inner cavity to reach the appropriate casting temperature; During the heating process of the furnace body, waste gas is generated. A water tank is installed at the top of the furnace body, and the heat of these internal waste gases is used to heat the water tank. This process realizes the recycling of heat, enabling the effective utilization of the waste gas heat that would otherwise be wasted and improving the energy utilization efficiency; After the water tank is heated, steam is generated. A number of drying components installed on both sides of the water tank dry the steam. This step may be to avoid the moisture in the steam having an adverse effect on other components or the casting process; Heat conduction structures are respectively arranged on both sides of the furnace body, and a number of heat storage rods are arranged inside the mobile platform. During the heating process of the furnace body, heat can be conducted through the heat conduction structures on both sides, and both ends of the heat storage rods are respectively close to the heat conduction structures on both sides of the furnace body. In this way, the heat storage rods can absorb and store heat. When the heating elements stop working or the heating power decreases, the heat stored in the heat storage rods can be slowly released to maintain the relative stability of the temperature inside the furnace, further improving the energy recovery and utilization efficiency and helping to stabilize the temperature environment of the casting process.

[0007] Furthermore, the gate assembly includes a support frame, the support frame is installed on the outer wall of the port of the furnace body, a gate is slidably connected to the inner wall of the support frame, a motor is installed on the top of the support frame, a reel is installed on the output shaft of the motor, a cable is wound around the outer wall of the reel, a roller is rotatably connected to the top of the support frame, the cable passes through the outer wall of the roller, and the end of the cable away from the reel is connected to the gate; The purpose of the above settings is that when the gate needs to be opened, the motor starts, and the output shaft of the motor drives the reel to rotate. During the rotation of the reel, the cable wound around its outer wall starts to be wound onto the reel. Since the end of the cable away from the reel is connected to the gate and the cable passes through the outer wall of the roller to play a guiding role, when the cable is wound, the gate will slide upward along the inner wall of the support frame, thus realizing the opening of the gate and facilitating the mobile platform to enter and exit the furnace body. When the gate needs to be closed, the motor rotates in reverse, the reel rotates in the reverse direction, the cable gradually unwinds from the reel, and the gate slides downward along the inner wall of the support frame under its own gravity until it closes, and then the gate seals the port of the furnace body.

[0008] Further, a plurality of installation grooves for installing channels are formed inside the mobile station, and a plurality of through holes are installed on the upper surface of the mobile station.

This structure enables the waste gas in the furnace body to enter the second chamber of the water tank, and the first chamber can be connected with an external water system through the water pipe to realize heat exchange and transfer. The heat in the waste gas heats the channel and gradually heats the water inside the water tank to form steam, and the generated steam is used for reutilization.

[0011] Further, a connecting pipe is connected to the first chamber, and the connecting pipe is installed outside the water tank; The purpose of the above setting is that through the connection between the connecting pipe and the first chamber, using the principle of the communicating vessel, the water level in the first chamber can be intuitively displayed, so as to determine whether to add water to the inside of the first chamber.

[0012] Further, the heat conduction structure includes a heat conduction plate. First through grooves are respectively provided on both sides of the furnace body.

[0015] Furthermore, a guide rail groove is formed on the upper surface of the bottom plate.
