Description

TECHNICAL FIELD

[0001] The present application relates to a heat transfer mold, in particular a simple universal heat transfer mold, belonging to the technical field of mobile phone shell processing equipment accessories. BACKGROUND

[0002] Processing mobile phone shells through heat transfer is a low-cost, high-flexibility personalized customization process, suitable for small-batch production or personal DIY, and can realize high-definition pattern transfer.

[0003] The essence of heat transfer is pattern transfer under high temperature and high pressure. The designed pattern is first printed on special heat transfer paper, and then high temperature is provided by a heating device (such as a heat transfer machine) to make the ink on the transfer paper penetrate into the surface of the mobile phone shell. After cooling, a firm and wear-resistant pattern is formed, and the pattern has no glue feeling and does not fall off.

[0004] Currently, a heat transfer mold is used in the heat transfer process. The mobile phone shell to be processed is sleeved on the heat transfer mold, and the heat transfer mold is used to support the mobile phone shell to maintain its shape unchanged during the heat transfer process, so as to ensure the heat transfer effect and quality.

[0005] Due to the great difference in size of mobile phones, the size of the corresponding mobile phone shells will also vary. The common heat transfer mold is customized according to the mobile phone shell. In order to be suitable for different mobile phone shell processing, a plurality of heat transfer molds are usually provided for a heat transfer machine. Not only is it inconvenient to manage and store, but also when in use, it is necessary to specially find a heat transfer mold suitable for the mobile phone shell to be processed, which increases the trouble of use and reduces the efficiency.

[0006] The universal heat transfer mold in the prior art inevitably has some empty spaces around due to its own structure, which causes a large area of the mobile phone shell to be suspended below during the heat transfer process.
