[0001] The utility model relates to the field of shoe heel processing, in particular to a hot pressing die for a TPU shoe heel processing hot press. Background Technique
[0002] The hot pressing die for TPU shoe heel processing is a professional device. It presses the TPU material into a specific shape and structure by applying heating and pressure in a hot press. The setting and production of this die need to comprehensively consider various factors such as the characteristics of the TPU material, the shape requirements of the shoe heel, and production efficiency. The die is usually made of materials with high temperature resistance, high strength, and high wear resistance, such as steel, alloy, etc., to ensure its stability and accuracy in a long-term high-temperature and high-pressure environment.
[0003] During the long-term use of traditional hot presses for TPU shoe heel processing, since traditional heating equipment is generally set at a constant temperature, during long-term use, equipment wear and aging may lead to inaccurate temperature control, and sometimes the temperature may be too high, causing the TPU material not to reach the appropriate temperature range before pressing, thereby affecting the forming quality and the physical properties of the product. In addition, due to the lack of a precise control mechanism for the pressure applied between the die and the press head, the pressure distribution may be uneven or too large, which not only affects the product quality but also may cause additional wear to the die and shorten its service life. Content of the Utility Model
[0004] Based on this, the purpose of the utility model is to provide a hot pressing die for a TPU shoe heel processing hot press to solve the technical problems of poor forming quality, damaged physical properties of the product, and shortened service life of the die caused by inaccurate temperature control and inaccurate pressure application in traditional hot presses.

Check that the display on the control panel 103 is normal, and that the thin-film pressure sensor 304 and the infrared temperature sensor 206 are correctly connected. According to the production requirements, set the temperature of the hot press in advance and start the equipment for preheating to ensure that the mold reaches the required working temperature;
[0044] Start the hot press. The cylinder block 201 drives the piston rod 202 to descend, pushing the heel pressing seat 203 and the heel pressing block 204 downward. The heel pressing block 204 gradually approaches the heel support 302 until the two are closely fitted to form a closed pressing space;
[0045] During this process, the infrared temperature sensor 206 monitors the temperature inside the pressing space in real time, transmits the data to the control panel 103, and the operator can adjust the heating power according to the displayed data to ensure that the temperature is stable within the set range. The thin-film pressure sensor 304 monitors the pressure distribution between the mold and the TPU material to ensure that the pressure is evenly applied. If the pressure is uneven, the operator can correct it by adjusting the stroke or pressure setting of the cylinder block 201;
[0046] Maintain for a certain period of time at the set temperature and pressure to fully soften and form the TPU material. The length of this stage depends on the characteristics of the TPU material and the shape complexity of the required product.
