Abstract

The utility model discloses an automobile -used novel air cleaner filter core, including the filter core main part, there is a plastics frame filter core main part outside establishes the profile of tooth filter cloth in, is equipped with the looping -in hangers on the plastics frame, is provided with the anti -overflow muscle on the installation hangers, and injection moulding is passed through with the filter cloth to the filter core main part, and the mould middle finishing is put into as the inserts to the filter cloth, forms the plastics frame through moulding plastics and combines to become an organic whole with the filter cloth. In the filter core main part embedding rubber coating mould, utilize thermoplastic elastomer PP+EPDM material secondary to mould plastics for parcel one deck elastomer materials also is exactly the elastomeric seal ring on the installation hangers at filter core main part border. The utility model discloses reduced auxiliary material input, promoted production efficiency simultaneously at reduce cost, guaranteed the part size for air cleaner sealing performance is protected.

Description

A kind of Novel vehicle air cleaner cartridge

Technical field

The utility model relates to air filter for vehicle, particularly a kind of air filter for vehicle filter core.

Background technique

At present, for ensureing filter core and air-strainer fitting tight, prevent the dust in air from directly entering motor, cause motor premature wear, the common practice fills a rubber weather strip to air cleaner cartridge, air filter housing and cartridge seal is realized by rubber compressive strain, Stamping Steel Ribbon and filter core assemble exists phenomenon of not fitting, and in assembly process, easy warpage, affects sealing, in order to stop this phenomenon, current way is the gluing process when assembling.

Above air cleaner cartridge structure, can be with the problem of serving in the middle of reality uses, it comprises: one, filter core cost is high, and filter core assembly needs to use four kinds of materials, filter cloth, plastic frame, rubber seal, glue; Two, cartridge seal strip adoption sulfidization molding, productive temp is long, and efficiency is low; Three, assembling trouble, manufacturing efficiency is low; Four, the factor such as irregular or Stamping Steel Ribbon distortion of gluing causes sealing inefficacy hidden danger larger; Five, for monolateral plug-type air filter structure, cartridge seal circle can insert and warpage in fastening rotary course at air filter housing.

Model utility content

For the problems referred to above, the utility model devises a kind of Novel vehicle air cleaner cartridge, filter core plastic frame and Stamping Steel Ribbon are combined as a whole by quadric injection mould mode by this filter core, decrease auxiliary material to drop into, reducing costs improving production efficiency, guarantee accessory size simultaneously, air-strainer sealability is protected.

For achieving the above object, the utility model is by the following technical solutions:

A kind of Novel vehicle air cleaner cartridge, comprises filter core main body, it is characterized in that: described filter core body exterior has plastic frame, inside establish profile of tooth filter cloth, plastic frame is provided with annular hangers is installed, install on hangers and be provided with anti-overflow muscle, hangers edge is installed and is provided with elastomeric seal ring.

Further, above-mentioned anti-overflow muscle is near the encapsulate edge of elastomeric seal ring, and anti-overflow muscle and encapsulate edge keep 0-0.5mm gap.

Further, above-mentioned filter core main body and filter cloth are by molding and forming, and filter cloth is put into mould as inserts and processed, and are combined into one by injection moulding formation plastic frame and filter cloth.

Further, above-mentioned filter core elastomeric seal ring is provided with sealed muscle.

The utility model filter core made an entirety by originally needing the product assembled, and product size precision is ensured, saved material and dropped into, shorten the process-cycle, reduce assembly process.Compare the structure of existing filter core, the utility model can reduce costs simultaneously effectively improving production efficiency, improving product reliability simultaneously.

When mounted, the utility model is applicable to various structures air cleaner assy, and effectively can solve the tightness potential problem that filter core is connected with air filter housing, filter core integral type is integrated, after avoiding repeatedly maintaining dismounting, Stamping Steel Ribbon lost efficacy, and greatly promoted filter core working life.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is A-A structure sectional view in Fig. 1;

Fig. 3 is the close-up schematic view in B portion in Fig. 2.

Embodiment

As shown in Figure 1, 2, 3, a kind of Novel vehicle air cleaner cartridge, comprise filter core main body, described filter core body exterior has plastic frame 2, inside establish profile of tooth filter cloth 1, plastic frame 2 being provided with annular hangers 21 is installed, install on hangers 21 and be provided with anti-overflow muscle 22, hangers limit 21 being installed along being provided with elastomeric seal ring 3.Above-mentioned anti-overflow muscle 22 is near the encapsulate edge of elastomeric seal ring 3, and anti-overflow muscle and encapsulate edge keep 0-0.5mm gap.

Described filter cloth 1 uses nonwovens or the air filter paper of TPE material, the modification Reinforced Polypropylene material that plastic frame 2 uses, elastomeric seal ring 3 uses thermoplastic elastomer (TPE) PP+EPDM material, filter cloth 1 after folding forming embeds in injection mould by the utility model filter core, utilize modification Reinforced Polypropylene material injection shaping, filter cloth 1 and plastic frame 2 are combined as a whole and become filter core main body, finally the filter core main body of molding and forming is embedded in encapsulation die, utilize thermoplastic elastomer (TPE) PP+EPDM material secondary injection moulding, make the installation hangers 21 on filter core body edge edge wraps up one deck elastomeric material i.e. elastomeric seal ring 3.And the elastomeric seal ring 3 of filter core is provided with sealed muscle 31.

Described plastic frame 2 is designed with hangers 21 is installed, hangers 21 edge is installed and is provided with anti-overflow muscle 22, anti-overflow muscle 22 is close to the encapsulate edge of elastomeric seal ring 3, and keep 0 ~ 0.5mm gap (H represents in figure 3) with encapsulate edge, prevent pressure in injection moulding process from flinging mold joint and produce the glue that overflows, simultaneously in injection moulding process, be subject to melt temperature conduction softening for plastic frame 2, the inside crumple of high pressure inject state lower frame, product overflow glue distortion, design anti-overflow muscle 22 and can prevent filter core plastic frame 2 inwardly crumple in injection process, thus ensure product size and outward appearance.

The utility model reduces material for core and drops into, and shortens man-hour, reduces operation, and cost reduces by 10%, and manufacturing efficiency increases by 20%, improves product reliability simultaneously, reduces the market risk.

The above, it is only better embodiment of the present utility model, not any pro forma restriction is done to the utility model, every according to know-why of the present utility model to any simple modification made for any of the above embodiments, equivalent variations or modification, still belong in the scope of technical solutions of the utility model.
