Description

Technical Field

[0001] The utility model relates to the technical field of air filter processing molds, in particular to a pre-shrinking processing mold for an automotive air filter. Background Technique

[0002] Air filters are mainly applied in fields such as pneumatic machinery and internal combustion machinery. Their function is to provide clean air for these mechanical equipment to prevent these mechanical equipment from inhaling air with impurity particles during operation, which increases the probability of abrasion and damage. The main components of an air filter are a filter element and a housing. Among them, the filter element is the main filtering part, undertaking the gas filtering work, and the housing is an external structure that provides necessary protection for the filter element. The working requirements of an air filter are to be able to undertake high-efficiency air filtration work, not add too much resistance to air flow, and be able to work continuously for a long time.

[0003] Currently, after most injection molding molds for air filter housings complete the injection molding of the housing, it is not convenient to take out the molded housing. Therefore, during the process of taking out the housing, it is easy to damage the housing. Moreover, most injection molding molds for air filter housings cannot quickly cool the injected housing, which increases the housing molding time and reduces the work efficiency.
