Intelligent temperature control mold for hot bending of 3C member, and control method thereof

Abstract

The invention discloses an in intelligent temperature control mold for hot bending of a 3C member, and a control method thereof. The mold comprises an upper mold and a lower mold, the upper mold is stitched on the lower mold, an accommodating cavity is formed between the upper mold and the lower mold, the upper mold and the lower mold are respectively connected with a primary heating device, a secondary heating device is arranged in the lower mold, a heat conducting seal plat is mounted at the bottom surface of the lower mold, and the mold is heated by the control of the primary heating deviceand the secondary heating device in order to effectively control the temperature. The mold and the control method have the advantages of high temperature rising rate, small hysteresis effect, and easiness in realization of temperature regulation.

Description

technical field [0001] The invention belongs to the technical field of hot-bending processing of 3C components, in particular to an intelligent temperature-controlled mold for hot-bending 3C components and a control method thereof. Background technique [0002] In the 3C industry, the application of transparent components in the industry continues to grow, especially with the rapid advancement of 5G technology, glass components are widely used in terminal communication products, especially components with curved surfaces. At present, due to the large market demand, 3C components made of curved glass are generally made of planar components through a hot-bending process (built into the hot-bending equipment) to form the curved complex shape required by the design. However, since glass and other materials are amorphous substances, if the bending temperature is too low, the 3C components are easy to break; on the contrary, if the bending temperature is too high, the 3C component...

Problems solved by technology

However, the above-mentioned methods all adopt a single-stage heating method, that is, directly heat the mold

However, the mold itself has thickness and volume, and the internal shape and structure are complex. The single heating method leads to a large gap between the temperature distribution of the 3C components to be heated and the expectation, which also leads to the generally low hot bending yield in the current 3C industry. an important reason for
