Description

Technical Field

[0001] The utility model belongs to the technical field of cup cover processing molds, and more specifically, particularly relates to a punching mold for cup covers. Background Art

[0002] Moulds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die-casting or forging, smelting, stamping and other methods. Injection moulds are generally used to produce some plastic products, and plastic cup forming moulds specifically refer to the plastic that is melted by heat and injected into the mould cavity by the injection molding machine under high pressure. After cooling and solidification, the formed product is obtained. Different types of moulds have various shapes and functions according to their different usage and production processes.

[0003] Based on the above, the inventors have found the following problems: most of the current cup lid stamping dies often require manual adjustment of plastic sheets during the stamping process, resulting in low production efficiency, and the opening and closing of the molds can easily cause injuries to employees. At the same time, when stamping cup lids of different sizes, staff need to use tools to disassemble the stamping head, which is time-consuming and labor-intensive and has certain limitations.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a stamping die for a cup cover is provided, in order to achieve the purpose of having more practical value. Utility Model Content
