Description

Technical Field

[0001] This utility model relates to the field of filter injection mold technology, and in particular to an injection mold for a gas filter for cleaning appliances. Background Technology

[0002] In the manufacturing process of cleaning appliances, gas filters are key functional components, primarily used to intercept dust, particulate matter, and harmful gases to ensure the cleanliness of the emitted air. Because cleaning appliances typically require frequent filter replacement or cleaning, these components must possess high-precision filtration performance, good structural stability, and the cost advantages of mass production. Currently, the main manufacturing method for gas filters is injection molding, with the injection mold being the core production equipment. The design and manufacturing quality of the mold directly affect the filter's precision, strength, and production efficiency. Gas filters often have porous, thin-walled, or irregularly shaped structures, making demolding difficult with traditional molds, which can easily lead to deformation or breakage, affecting product yield.
