Abstract

The invention relates to a self-hinge foam folding box process. The self-hinge foam folding box process comprises the following operation steps of mold closing, pre-blowing, feeding, material returning, heating 1, heating 2, double-sided heating, water cooling, vacuum cooling, folding pressing, secondary heating 1, secondary heating 2, secondary double-sided heating, secondary water cooling, secondary vacuum cooling and demolding. The self-hinge foam folding box process adopts a special process, special equipment and a special mold, folding of a self-hinge foam box is achieved under the condition that external hinges are not needed, 60% of the size can be saved after the self-hinge foam box is folded, moreover, the self-hinge foam box can be recycled, and therefore, the logistics transportation cost is greatly reduced.

Description

technical field [0001] The invention relates to the packaging field of cold chain logistics, in particular to a self-hinge foam folding box process. Background technique [0002] At present, the foamed plastic boxes used in the market are processed and formed by foaming molds. After the molding, the product volume is large. During transportation and storage, this foamed plastic box will take up a lot of space, and the transportation and storage costs are relatively high. In order to To maximize the use of limited space in the process of transportation and storage, a folding structure is required to fold the rigid foam plastic box into a flat state, and then unfold it when using, so as to solve the problems of cost and space utilization. Existing foam plastic boxes generally have external hinges, which not only cost relatively high, but also take up large space for the external hinges, which is unfavorable for storage and transportation.
