Abstract
The utility model discloses a filter element end cover, which comprises an end cover body and a non-woven fabric sealing washer, wherein the end cover body and the non-woven fabric sealing washer are integrally formed through insert molding. After integral formation through the insert molding, the upper edge of the outer ring of the non-woven fabric sealing washer and the upper end surface of the end cover body are at the same level. By adopting the technical scheme, the filter element end cover has the advantages that: 1) the number of machining processes is reduced to one from two in the past and the working efficiency is improved; 2) since a non-woven fabric is directly placed on an injection mold and is injection-molded in the end cover in an integral formation way, connection is firm, the situation that the non-woven fabric falls off is avoided, filter paper is not heated when a filter paper curing and sizing technology is adopted, and the filter paper is only required to be cured for one time; and 3) by adopting the method, the environment is protected, and pollution caused by floating non-woven fabrics is greatly reduced.
Description
Technical field
The utility model relates to a kind of filter core end cover structure.
Background technology
Filter core in the market mainly contains upper and lower end cap, refill, and central tube, compositions such as nonwoven sealing ring, as illustrated in fig. 1 and 2, wherein product end cap adopts the directly super welding nonwoven of upper and lower end cap seal washer mode to reach sealing effectiveness.As application number be 200810121623.9 Chinese invention patent in disclosed filter element on March 18th, 2009, the end cap seal circle adopts nonwoven cloth material to make, nonwoven cloth material adopts the ultrasonic bonding mode to be welded on the described end cap.There are three problems in the bonding nonwoven of this kind mode:
1, end cap by injection moulding be accomplished to the weldering nonwoven divide two processes to finish, efficient is not high;
2, there is the unstability of equipment in ultrasonic bonding, and the nonwoven of welding is insecure or the excessive nonwoven of intensity occurs and weld damaged situation, and is not attractive in appearance in appearance; As not prison welding, filter core the nonwoven dropping situations can occur in actual use, as weld excessively, nonwoven can occur and burn situation, closely cause the damaged obscission of nonwoven, these two kinds of phenomenons cause comes off and all has nonwoven and fall into and cause lubricant passage way to stop up in the filter block, thereby influences the engine normal operation
Fiber fines when 3, nonwoven is welded in ultrasonic filter on the nonwoven can form floating situation under the vibration of ultrasonic wave effect, pollute operationlocation's environment.
The utility model content
Technical problem to be solved in the utility model just provides a kind of simple in structure, technology convenience, can prevent the filter core end cap that nonwoven comes off.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of filter core end cap, comprise end cap body and nonwoven seal washer, and it is characterized in that: described end cap body and nonwoven seal washer are finished by the piece moulding inlaying integral forming process.
As preferably, described nonwoven seal washer is an annular, and the upper edge of nonwoven seal washer outer ring is concordant with end cap body upper surface.The upper edge of nonwoven seal washer outer ring, the one-body molded back of piece moulding inlaying is concordant with end cap body upper surface, earlier the circular ring type nonwoven is embedded in the mould before the injection moulding, and through the matched moulds injection molded, this kind accessory compact conformation, good looking appearance.
The utility model has the following advantages owing to adopted technique scheme:
1, manufacturing procedure is reduced to an operation by two original operations, has improved operating efficiency.
2, nonwoven is placed directly on the injection mold, adopts the one-shot forming mode that nonwoven is injected in the end cap, be connected firmly, the nonwoven dropping situations can not occur.Filter paper solidifying and setting effect: this technology no longer heats filter paper, and filter paper only needs one-step solidification.
3, this mode has been protected working environment, has reduced the contamination phenomenon because of the floating formation of non-woven fabrics fiber to a great extent.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is existing end cap vertical view;
Fig. 2 is existing end cap cross-sectional schematic;
Fig. 3 is for improving the rear end cap schematic diagram.
The specific embodiment
Filter core end cap as shown in Figure 3 comprises end cap body 1 and nonwoven seal washer 2, and described end cap body and nonwoven seal washer are finished by the piece moulding inlaying integral forming process.Described nonwoven seal washer is an annular, earlier circular ring type nonwoven seal washer is embedded in the mould before the injection moulding, through the matched moulds injection molded.
Claims (2)
1. a filter core end cap comprises end cap body (1) and nonwoven seal washer (2), it is characterized in that: described end cap body (1) and nonwoven seal washer (2) are finished by the piece moulding inlaying integral forming process.
2. a kind of filter core end cap according to claim 1 is characterized in that: described nonwoven sealing ring (2) is an annular, and the upper edge of nonwoven seal washer outer ring, the one-body molded back of piece moulding inlaying is concordant with end cap body (1) upper surface.
