Abstract
It the utility model is related to a kind of air filter housing, it is made by plastic material integrated injection molding, in cylinder bell, the upper end of housing is equipped with air outlet slit, the periphery lower part of housing is equipped with air intlet, housing lower end is equipped with annulus bottom, surface of shell is equipped with a plurality of reinforcing rib, including around the housing periphery cyclization ring stiffener set and the waling being arranged in an axially parallel mode.This air filter housing on housing by setting reinforcing rib, enhance the intensity of housing, housing is firm, solid, waling is set on the outside of air intlet, and be connected with the annulus bottom of lower end, using the guide functions of waling, the melt plastic cement flow equilibrium filled in mould is made in injection, so as to reduce deformation, improve circularity.
Description
Technical field
It the utility model is related to air cleaner, and in particular to a kind of air filter housing.
Background technology
The main function of air filter for automobile is to provide clean air for engine, with preventing engine at work
Suction carries the air of impurity particle and increases the probability of abrasion.Air cleaner is mainly made of filter core and housing, and filter core is
Main filtration fraction, carries the filtration of gas；Housing provides necessary outer protection, while whole housing for filter core
The cavity surrounded also has certain sound-deadening and noise-reducing function.
Most of air filter housing, its shape are drum type brake, and cylinder sandwich type element is led to using plastic material
Injection molding is crossed to produce, since air filter housing is equipped with dirty air tube opening so that this be on mould formed it is larger
Holes, greatly hinders flowing of the melt plastic cement at this, makes melt plastic cement flowing and other region imbalance of flow at this,
It can not be simultaneously filled with the air filter housing bottom of filling end so as to cause, injection pressure is uneven in mould, leads
Deformation of products is caused, the circularity of the particularly rounded bottom of air filter housing is poor, causes air filter housing can not be into
Row assembling.In order to improve its circularity, often using the method for adjusting the molding parameter of injection molding machine or doing predeformation, but due to being produced
The influence of product geometry and mold design, effect unobvious and cost is higher.In addition, the air cleaner for passing through injection molding
The intensity of housing is smaller, insecure, can not meet requirement.
Utility model content
The purpose of this utility model is exactly to solve the above-mentioned problems and provides a kind of air filter housing structure.
The purpose of this utility model is achieved through the following technical solutions：
A kind of air filter housing, is made by plastic material integrated injection molding, and in cylinder bell, the upper end of housing is set
Have air outlet slit, the periphery lower part of housing is equipped with air intlet, housing lower end is equipped with annulus bottom, and surface of shell is equipped with a plurality of
Reinforcing rib, including around the housing periphery cyclization ring stiffener set and the waling being arranged in an axially parallel mode.
The air outlet slit is circle, and the air intlet is with the square of chamfering.
The side of the air intlet is equipped with the waling being connected with the annulus bottom.
The reinforcing rib is the raised line of prominent surface of shell.
The section of the raised line is circular or square, and size is in 2-5mm.
Spacing between the reinforcing rib is 3-5cm.
This air filter housing, by setting reinforcing rib on housing, enhances the intensity of housing, housing is firm, knot
It is real, waling is especially set on the outside of air intlet, is connected with the annulus bottom of lower end, utilizes leading for waling
Stream acts on, and the melt plastic cement flow equilibrium filled in mould is made in injection, so as to reduce deformation, improves circularity.This air filter
Clear device housing can effectively improve circularity problem, reduce the assembly problem come by Zona transformans, reduce injection molding machine die trial number, expansion
Window is molded, shortens time of product development.
Concrete principle is, air filter housing is equipped with air intlet into glue cast gate, during injection, melt plastic cement from into
Glue cast gate has the function that water conservancy diversion by the waling in air filter housing, can accelerate melting modeling to bottom filling
Flowing of the glue at air intlet so that at this slower melt plastic cement of original flowing because of the promotion of waling water conservancy diversion, its
Flowing velocity is accelerated, and is unlikely to lag behind other regions, and can the speed identical with the holding of other regions be filled to end,
The rounded bottom in filling end is simultaneously filled with, reaches filling and balances, the injection pressure distribution ratio in such mold cavity
More uniform, volume contraction is also uniform, therefore deformation of products is small, and the deformation of especially rounded bottom is greatly improved, so as to reach
To the purpose for improving its circularity.
