Therefore, they should not be construed as limitations on this utility model.

[0016] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described below.

[0017] To address the problems existing in the background technology, this application proposes the following technical solution: a forging die preheating device, comprising a preheating box 1, the preheating box 1 being externally wrapped with polyurethane insulation material, a preheating groove 2 being provided inside the preheating box 1, an electromagnetic induction heating coil 12 being fixedly connected inside the preheating groove 2, a support frame 13 being fixedly connected inside the preheating groove 2, the support frame 13 having multiple sets of through holes 14, and the through holes 14 being connected to the preheating groove 2, the preheating box 1 being provided with a conveying assembly for conveying the die to the preheating groove 2, and a support assembly for supporting the die being provided outside the conveying assembly; the preheating box 1, as the core load-bearing structure of the entire device, has excellent heat insulation performance due to the polyurethane insulation material externally wrapped with it. Because of its high closed-cell rate and low thermal conductivity, polyurethane material can effectively prevent heat loss from the inside of the preheating box 1 to the outside, greatly reducing heat loss. In practical applications, this can not only reduce energy consumption and save on electricity costs during the preheating process, but also maintain the stability of the internal temperature of the preheating box 1, avoiding temperature fluctuations caused by heat loss and affecting the preheating effect of the mold.

[0018] The preheating tank 2 inside the preheating chamber 1 provides a dedicated space for mold preheating, and the fixedly connected electromagnetic induction heating coil 12 is the key component for achieving rapid and efficient heating. The principle of electromagnetic induction heating is to use an alternating magnetic field to generate an induced current within the mold, causing the mold itself to heat up. This heating method features rapid heating and uniform heating. Compared to traditional heating methods, it avoids localized overheating or insufficient heating of the mold, ensuring uniform temperature throughout the preheating process, eliminating potential thermal stress risks, and thus improving the mold's performance and service life during forging. The support frame 13 and its through holes 14 within the preheating tank 2 not only provide stable support for the mold but also promote the circulation of hot air within the preheating tank 2, allowing heat to be better transferred to all parts of the mold, further improving preheating efficiency and uniformity. The installation of the conveying and support components ensures automated conveying and stable placement of the mold, making the entire preheating process more convenient and efficient, reducing the tediousness and errors of manual operation.

[0019] In this embodiment, the conveying assembly includes a sprocket 5 and a chain 6. Fixed frames 3 are fixedly connected to both ends of the preheating box 1. A rotating rod 4 is rotatably connected to the fixed frame 3, and a sprocket 5 is fixedly connected to the outside of the rotating rod 4. The chain 6 is sleeved on the outside of the sprocket 5. The output end of the motor 11 is fixedly connected to the outside of one of the fixed frames 3. The conveying assembly uses a transmission structure of sprocket 5 and chain 6, which has significant advantages in terms of simple structure and reliable transmission. The fixed frames 3 at both ends of the preheating box 1 provide a stable mounting base for components such as the rotating rod 4 and sprocket 5, ensuring that the entire transmission system will not shake or shift during operation, thus guaranteeing the stability of mold conveying. The fixed connection between the rotating rod 4 and the sprocket 5 allows the power of the motor 11 to be efficiently transmitted to the sprocket 5, thereby driving the chain 6 for transmission. In actual operation, the motor 11, as the power source, drives the rotating rod 4 to rotate, causing the sprocket 5 to drive the chain 6 at a stable speed, smoothly conveying the mold placed on the chain 6 into the preheating tank 2. This transmission method boasts high transmission efficiency, enabling continuous and rapid mold transport and meeting the preheating efficiency requirements of molds in industrial production. Furthermore, the combination of sprocket 5 and chain 6 requires relatively simple maintenance during long-term use; only periodic lubrication and inspection are needed to ensure normal operation, reducing equipment maintenance costs. In addition, the design of this conveying assembly allows for flexible adjustment of the motor 11's speed and running time according to actual production needs, thereby controlling the mold's conveying speed and preheating time in the preheating tank 2. This adapts to the preheating requirements of molds of different specifications and materials, improving the device's versatility and applicability.

[0020] In this embodiment, the support assembly consists of multiple sets of support plates 7 fixedly connected to the outside of the chain 6. A fixing plate 8 is fixedly connected to the outside of each support plate, and a latch 9 is provided on the outside of the fixing plate 8. A limiting plate 10 is engaged in the latch 9. All support plates 7, fixing plates 8, and limiting plates 10 are made of high-temperature resistant materials. The support plates 7 are used to support and place the mold. The design of the support assembly fully considers the stability and safety requirements of the mold during the preheating process. The multiple sets of support plates 7 fixedly connected to the outside of the chain 6 provide uniform and stable support force to the mold, ensuring that the mold will not tilt or fall during conveying and preheating. The support plates 7, fixing plates 8, and limiting plates 10 are all made of high-temperature resistant materials, which allows the support assembly to work stably for a long time in the high-temperature environment inside the preheating chamber 1 without deformation or damage due to high temperatures, ensuring the reliability of the mold support structure. The cooperation design between the latch 9 on the outside of the fixing plate 8 and the limiting plate 10 further enhances the fixing effect on the mold. The limiting plate 10 engages with the bayonet 9, restricting the horizontal movement of the mold and preventing displacement due to vibration or other factors during chain drive. This ensures the mold remains in the correct preheating position, guaranteeing uniform and consistent preheating. In practical operation, this support component design facilitates mold placement and removal. Operators simply place the mold on the support plate 7 and secure it using the limiting plate 10, making the operation quick and easy. Furthermore, when changing to molds of different sizes, simply adjusting the position of the limiting plate 10 or replacing it with a suitable one adapts to the support requirements of molds of varying sizes, improving the flexibility and practicality of the device and providing a reliable guarantee for efficient preheating of forging dies.

[0021] The usage method of this embodiment is as follows: Place the mold on the support plate 7, start the motor 11 to drive the rotating rod 4 to rotate, the rotating rod 4 to drive the sprocket 5 to rotate, the sprocket 5 to drive the chain 6 to transmit the mold to the preheating tank 2, and heat it through the electromagnetic induction heating coil 12. After heating is complete, the mold is transported out by reversing the motor 11.
