Off-line heating method for hot-pressing die machining

Abstract

The invention provides an off-line heating method for hot pressing die machining. The method comprises the following steps that: firstly, a mold is cleaned, a release agent is smeared, and residues used last time are removed; secondly, a hot-pressing material is prepared, and the material is pre-pressed; thirdly, the mold is preheated, the mold is heated to the temperature needed by hot pressing before entering a production line, and then the processed mold is fed into the production line; fourthly, the mold is fed and hot pressing is carried out, the pre-pressed hot-pressing material is put into the mold, mold closing pressurization is carried out, the pressurization is kept to be constant, the temperature change in the hot pressing process is detected, and the stability of the temperature and the accuracy of the pressurization time are ensured; fifthly, the mold is cooled, the mold is sent out of the production line, and cooling of the mold is accelerated through a cooling pipeline; and sixthly, demolding machining is conducted, specifically, the cooled mold is subjected to demolding treatment, and a demolded product is cleaned and polished. The method has the beneficial effects that the production efficiency is improved, and the heating and cooling time is shortened.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to an off-line heating method for hot pressing mold processing. Background technique [0002] After the current thermoforming floppy drive heating mold is mass-produced, it will take a long time to heat in the county during the production process, and it also needs a long cooling time, which slows down the production efficiency and the time for mold change, resulting in The decline in output requires process improvement, and in the process of in-line heating, cold-short equipment and pipelines need to pass through the processing line, causing mutual interference between equipment and potential safety hazards. Instability remains. Contents of the invention [0003] The purpose of the present invention is to provide an off-line heating method for hot-pressing mold processing with simple process and high production efficiency, especially suitable for hot-pressing molds.
