| 摘要 | PURPOSE: To provide a plurality of relatively small, highly styled vent openings by defining an annular row of radially off-set pairs of air passageways cores in a mold cavity by interlocking inboard and outboard pocket cores. CONSTITUTION: A mold apparatus is provided with a 'split core' construction adapted to produce radially off-set but communicating outboard and inboard pockets 42 and 44, and the split core construction comprises a series of outboard pocket cores 330 which project upwardly from a lower mold part 202 at the appropriate locations on a mold face 230 to form outboard pockets 42 in an overlay 26. An upper mold part 206 likewise has a plurality of inboard pocket cores 332, one for each of the inboard pockets 44, which are affixed to the underside of a clamp plate 244 and protrude downwardly therefrom. Each inboard core 332 has a cross-sectional configuration complimentary to vent openings 32 and adapted to fit therethrough with a close sliding fit. | ||||||
