Abstract
An injection molding apparatus ( 10, 110 ) for molding an annular thermoplastic element, such as an annular closure element (E) with no more than a single weldline in the annular extent of the thermoplastic element. The thermoplastic element is molded in an annular mold cavity ( 12, 112 ), and moldable thermoplastic material (M) is introduced into the mold cavity from a coaxially-aligned annular flow path ( 18, 118 ) that is defined between a sliding sleeve ( 24, 124 ) and an annular member ( 22, 122 ). The sliding sleeve surrounds and is slideable with respect to a fixed pin ( 26, 126 ) and is slideable between a first, or forward, position, where no thermoplastic material can flow into the mold cavity, and a second, or rearward, position, where thermoplastic material can flow into the mold cavity. Thermoplastic material is introduced into the annular flow path, at a location upstream of the second position of the sliding sleeve, in a single stream through a passage ( 28, 128 ) to limit the weldlines in the molded thermoplastic element to no more than one.
Claims (8)
1. Apparatus for introducing a moldable thermoplastic material into an annular mold cavity to mold an annular thermoplastic part that has no more than a single weld line therein, said apparatus comprising:
an annular mold cavity having an annular opening thereinto;
a fixed pin axially aligned with the opening of the mold cavity and being immovable during molding relative to the opening of the mold cavity;
a passage extending through said fixed pin for venting air from said mold cavity;
an annular sleeve surrounding the fixed pin and being moveable with respect to the fixed pin between a first position that is adjacent to the mold cavity and a second position that is away from the mold cavity to define, with the fixed pin when in the second position, an annular path for introducing moldable thermoplastic material into the annular opening of the mold cavity; and
means for introducing moldable thermoplastic material into the annular path, at a location upstream of the second position of the annular sleeve, in no more than a single path.
2. Apparatus according to claim 1 wherein:
said means for introducing comprises a passage that extends at an acute angle with respect to a longitudinal central axis of said annulus mold cavity.
