Description

Technical Field

[0001] This utility model relates to the field of paper-plastic product processing technology, specifically to a processing mold for paper-plastic products that is easy to stack. Background Technology

[0002] Currently, in the production of paper-plastic products, molds are typically used for shaping. To ensure the quality and efficiency of the shaping process, drying holes need to be incorporated into the molds to ensure the pulp is dried evenly, resulting in paper-plastic products with fewer surface wrinkles. One of the main reasons for wrinkles on the surface of existing paper-plastic products is the incorrect number of drying holes during production. An incorrect number of drying holes leads to uneven drying speeds and insufficient drying force throughout the shaping process, resulting in wrinkles on the finished product. Currently, the number of drying holes in paper-plastic product molds is usually determined through experience or repeated testing, and cannot be based on the actual thickness and area of ​​the paper-plastic product being produced.

[0003] In the prior art, Chinese patent document with publication number CN220013218U was proposed to solve the above-mentioned technical problems. The technical solution disclosed in this patent document is as follows: a paper-plastic product anti-wrinkle processing mold, wherein a cavity is formed in the template frame of the lower template, and drying holes are densely distributed in the area of ​​the lower template located in the cavity. When in use, this utility model can calculate the required number of mold drying holes according to the area and thickness of each paper-plastic product, thereby achieving accurate processing of the number of drying holes, avoiding repeated processing of drying holes and insufficient number of drying holes, which would cause wrinkles on the surface of the paper-plastic product due to inconsistent drying speed caused by incorrect number of drying holes. Therefore, the surface of the paper-plastic product processed by the paper-plastic product processing mold of this utility model can be wrinkle-free.

[0004] To address the issue that the number of drying holes in the mold cannot be determined based on the actual thickness and area of ​​the paper-plastic product being produced, the existing technology calculates the required number of drying holes based on the area and thickness of each paper-plastic product. However, this method still results in problems such as difficulty in demolding the mold and inconvenience in stacking the processed paper-plastic products, leading to difficulties in storing the produced paper-plastic products and reducing storage space.
