Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a flip-top injection mold for a label printer. Background Technology

[0002] Injection molds are precision tools used for the mass production of plastic products. They are typically made of high-hardness steel and include core components such as cavities, gating systems, cooling systems, and lifting mechanisms. Their working principle involves injecting high-temperature molten plastic into the mold cavity, which then cools and solidifies before demolding to form the final product. Injection molds are a core technological foundation for achieving low-cost, high-quality, large-scale manufacturing of plastic products and are widely used in modern industrial fields.

[0003] Existing flip-top injection molds require a curved accommodating area to accommodate components such as label printers and the inner frame during the flip-top manufacturing process, thus enabling the flip-top's basic functions. However, this curved accommodating area makes the flip-top prone to damage during demolding due to uneven ejection forces.

[0004] Therefore, it is urgent to research and develop a flip-top injection mold for label printers to solve the above-mentioned technical problems. Summary of the Invention
