Description

Technical Field

[0001] The utility model relates to the technical field of easy-to-demold molds, and more particularly to an easy-to-demold mold for producing paper cups. Background Art

[0002] Paper cups are convenient and hygienic daily necessities. They are typically produced using stamping dies to form paperboard. Traditional paper cup production dies are difficult to demold, especially around the bottom and edges. This results in low production efficiency and can even damage the cups. Furthermore, mold wear is inevitable in high-intensity production environments. The complex structure requires more parts to be regularly inspected and replaced, increasing maintenance costs. Therefore, an easy-to-demold mold for paper cup production is needed to address this issue.

[0003] Since the current paper cup production molds are complex and the initial cost of easy-to-demold molds is high, from the perspective of saving costs and adding simple components, the problem is solved by setting cooling components and changing the production sequence. Utility Model Content
