Description

Technical Field

[0001] The utility model belongs to the technical field of cup cover moulds capable of rapid demoulding, and more specifically, particularly relates to a cup cover mould capable of rapid demoulding. Background Art

[0002] The cup cover mold with rapid demoulding is a mold specially used for producing plastic cup covers. Its design and structure enable rapid and efficient demoulding during the injection molding process to improve production efficiency and reduce costs. The Chinese patent number: CN202221458405.6 discloses a cup cover mold with rapid demoulding, including a lower mold, an upper mold is arranged at the top of the lower mold, and a first hydraulic cylinder is fixedly arranged at the four corners of the top of the upper mold. The output shaft of the first hydraulic cylinder passes through the upper mold and extends to the bottom of the upper mold and is fixedly connected to the lower mold. The thread forming block is rotatably nested and arranged at the bottom of the upper mold. The two sides of the top of the lower mold and the top of the upper mold are jointly provided with a rapid demoulding mechanism. The driving motor in the rapid demoulding mechanism drives the thread forming block to rotate, and the clamping plate in the rapid demoulding mechanism clamps and fixes the finished cup cover. The utility model can demould the finished cup cover more conveniently, and at the same time, it can avoid the need to grind the bulge on the inner wall of the cup cover, save manpower, reduce the production difficulty and effectively improve the production efficiency.

[0003] Based on the above, the inventors found the following problems: the above patent can demold the finished cup lid more conveniently, and at the same time avoid the generation of protrusions on the inner wall of the cup lid that need to be polished, saving manpower, reducing production difficulty and effectively improving production efficiency. However, after the cup lid is injection molded, it is necessary to wait for the cup lid to cool down before it can be removed, and waiting for cooling takes a certain amount of time, which reduces work efficiency. At the same time, the device does not clean the molding groove after each injection molding. If there are impurities in the molding groove, it will affect the quality of the next cup lid.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a cup cover mold that can be quickly demoulded is provided, in order to achieve the purpose of having more practical value. Utility Model Content
