Patent ID: 7661953

Claim:
A die device for producing an exterior member/seal member assembly, said die device comprising: a first die comprising a first inner surface having a curved end portion; a second die comprising a second inner surface having a curved end portion, the second die cooperating with the first die to define a cavity between said first and second dies; and a slide core slidably mounted in a guide bore formed in the second die, wherein the slide core slidably projects into and retracts from the cavity, wherein the slide core comprises a recess-shaped portion at a side surface thereof and a top end portion connected to the recess-shaped portion abutting the first inner surface of the first die when the slide core projects into the cavity, dividing the cavity into two regions, a first region and a second region, wherein the curved end portion of the first inner surface of the first die and the curved end portion of the second inner surface of the second die are curved toward the second die and define a tapered portion of the second region that terminates at an end of the cavity where the first die abuts the second die, wherein at a position of the slide core being retracted into the guide bore the top end portion of the slide core is located flush with the second inner surface of the second die and extends a back surface of the second region and the second region expands to communicate with a space between the recess-shaped portion of the slide core and an inner wall of the guide bore, so that a space for molding the seal member is defined among the first inner surface of the first die, the second inner surface of the second die, the top end portion of the slide core, the recess-shaped portion of the slide core and the inner wall of the guide bore facing the recess-shaped portion, and wherein the recess-shaped portion of the slide core defines an end portion of the first region when the slide core projects into the main cavity.
