Description
- The application claims priority to U.S. Provisional Application No. 60/296,657, which was filed on Jun. 7, 2001.
- This invention relates to a method and apparatus for providing an attachment feature on an injection molded component without requiring any additional injection mold tooling actions to further form the attachment feature.
- Injection molded components are used in a variety of different applications in a vehicle. An example of one injection molded component is an air cleaner housing. In the past air cleaner housings have been installed into the vehicle by using separate push pin members and a grommet. The push pins are inserted into openings in a base portion of the air cleaner housing and are then pushed into a grommet that is mounted to a vehicle structure. This process is labor intensive and time consuming.
- One proposed solution has been to incorporate the details of the push pin directly into the housing by molding pin attachment features into the base of the air cleaner housing. This current process requires extensive injection mold tool actions to form pin attachment features. These mold actions include slide actions and/or running the parting line around the particular feature to create an undercut that retains the grommet. Such additional tooling actions increase the overall cost of the component.
- Thus, it is desirable to have an attachment feature that can easily be molded into an injection molded component without requiring extensive injection mold tooling actions, as well as overcoming the other above mentioned deficiencies with the prior art.
- A retaining assembly is used to attach an injection molded component to a vehicle structure. The molded component includes a base portion defining a bottom surface having at least one attachment member for attachment to a vehicle structural component. The attachment member is integrally formed as one piece with the base portion such that there is a continuous unbroken surface extending between the base portion and attachment member. The attachment member is formed as a cylindrical body portion that extends to a distal end having a retention member that cooperates with the vehicle structure component to retain the molded component to the vehicle structure. The retention member is formed with a plurality flanges spaced apart from one another and which extend out radially from the cylindrical body portion.
- Preferably, the injection molded component is an air cleaner housing and the retention members are integrally formed push pins. The push pins are inserted through a grommet or other similar component to attach the housing to the appropriate vehicle structure.
- In one disclosed embodiment, a pad is formed about at least a portion of the cylindrical body portion by a lower mold portion. The base portion of the component further defines a top surface that faces opposite from the bottom surface, and which includes at least one opening extending through the base portion from the top surface to the bottom surface adjacent the cylindrical body portion. The opening receives an upper mold portion, which is positioned at a predetermined distance apart from the lower mold portion. The flange is formed between the upper and lower mold portions.
- The method of forming an air cleaner housing component includes the following steps. An upper mold defines a top surface of the air cleaner housing component and includes at least one transversely extending male member defining a portion of the attachment member. A lower mold defines a bottom surface of the air cleaner housing component and includes at least one female member defining a portion of the attachment member. The upper mold is positioned relative to the lower mold by inserting the male member into the female member. The upper mold and male member are held at a predetermined distance apart from the lower mold and female member to define a gap that defines the shape of the air cleaner housing component. Material is injected into the gap to integrally form the attachment member and air cleaner housing component as a single piece. Preferably, a plurality of flanges is formed at a distal end of the attachment members between the upper and lower molds.
- The subject apparatus and method provide an attachment interface for an injection molded component that eliminates the need for additional injection mold tool actions, resulting in reduced costs and installation time. These and other features of the present invention can be best understood from the following specifications and drawings, the following of which is a brief description.

This provides for easy installation by applying a single vertical force to push theattachment members 20 into thevehicle structure 16. - A cross-section of the retainer head portion of the
attachment member 20 is shown in FIG. 3. Thecylindrical body portion 22 defines acenter 32 with theflanges 28 extending out radially away from thecenter 32. Each of theflanges 28 has abase 34 that extends out to atip 36. Preferably, theflanges 28 are narrower at thebase 34 than at thetip 36. Thetips 36 preferably form anarcuate surface 38. Thearcuate surface 38 facilitates push in force and helps accommodate for any mis-alignments between mating components. - As shown in FIG. 4, each of the
flanges 28 is orientated transversely to thecylindrical body portion 22. Further thecylindrical body portion 22 is preferably greater in length L1 than the length L2 of theflange 28. - As shown in FIG. 5, recesses or
pockets 40 are formed within thebase housing portion 14 to allow theflanges 28 to be formed between anupper mold half 42 and a lower mold half 44 (FIG. 6). A raisedpad portion 46 is also integrally formed about thecylindrical body portion 22 of theattachment member 20 during the molding process.

Theupper mold 42 has a profile that defines the contours of thetop surface 48 of thebase housing portion 14. Thelower mold 44 has a profile that defines the contours of thebottom surface 30. - The
upper mold 42 includes amale member 50 that extends from a base 52 to adistal end surface 54 with amale sidewall portion 56 extending between the base 52 andend surface 54. Thelower mold 44 includes a female member 58 defining abottom face 60 with afemale wall portion 62 extending upwardly from thebottom face 60 of themolds flanges 28 are formed between thedistal end surface 54 and thebottom face 60. - Material, such as plastic, is injected between the upper42 and lower 44 molds to form the
base housing portion 14. Preferably, themale member 50 is non-concentrically positioned within the female member 58 such that the material does not completely surround themale member 50. Thus, thecylindrical body portion 22 is formed between themale sidewall portion 56 and the femalewalled portion 62 at one side of themale member 50. - The
lower mold 44 includes agroove 64 or other similar formation that forms thepad portion 46. As shown in FIG. 6, a continuous unbroken surface extends from thebottom surface 30 of thebase housing component 14 to thepad portion 46, to thecylindrical body portion 22, and finally to theflange 28. - An
opening 66 that extends through thebase housing portion 14 from thetop surface 48 to thebottom surface 30 provides the clearance for themale member 50 of theupper mold 42 to make the undercutflange 28. No further mold tooling actions are required to form theattachment members 20. Once the mold halves 42, 44 are separated, theattachment members 20 can be pushed into place. - The method for forming the
attachment members 20 andbase housing portion 14 as a single piece includes the following steps. Theupper mold 42 is positioned relative to thelower mold 44 by inserting themale member 50 into the female member 58.
