Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a paper tray mold. Background Technology

[0002] Molds used for manufacturing paper lunch boxes on the market generally include an upper template, a lower template, a core plate, and a cavity plate. The core plate is fixed on the upper template, and the cavity plate is fixed on the lower template. The core plate has multiple cores, and the cavity plate has multiple cavities. The cores and cavities correspond one-to-one. When the mold is closed, the cores and cavities cooperate to form the paper lunch box product, and multiple paper lunch box products can be formed at one time. However, since multiple cavities are integrally formed on the cavity plate, when the mold is heated to form the product, the cavities will expand thermally, causing them to affect each other, which in turn affects product quality and damages the mold.

[0003] Therefore, further improvements are necessary. Utility Model Content
