[0002] Shoes are garments worn on the feet to protect them and facilitate walking. They are made of materials such as leather, cloth, and rubber. Shoes have a long history. The earliest footwear, made of animal hides, appeared during the Yangshao culture over 5,000 years ago. Shoes were a tool used by people to protect their feet from injury.

[0003] Currently, in the production of shoes, defective shoes need to be corrected in some cases, which requires the use of heating equipment to heat the sole, which can help separate the sole from the upper, so as to re-gluing, replacing the sole or upper. However, in actual applications, it is found that most conventional heating equipment can only heat a single shoe. Therefore, when a batch of defective products are processed together, the overall heating efficiency will be low. For this reason, a heating device for demolding the upper and bottom surfaces is proposed. Utility Model Content
