ABSTRACT:
The embodiment of the invention disclosed herein is directed to a one-piece molded fluid filter and a mold construction for making the same. The mold construction is provided with first and second body portions having abutting surfaces forming a parting line. A plurality of axially spaced apart semicircular recesses are formed in the body portions to provide annular recesses in the mold. The parting line of the two body portions passes across the central area of each of the annular recesses. Longitudinal channels are formed in each of the body portions to provide a flow path for the injected resin. A core member having a plurality of axially and radially outwardly directed splines is inserted between the body portions and is dimensioned so that the splines come in direct contact with the lands between the recesses of the mold body portions. A large annular recess is provided centrally of the mold body portions and enables the injected resin to flow from an inlet gate along the longitudinal channels of both body portions to completely fill the mold.
