Patent ID: 8628322

Claim:
A mold apparatus for use in injection molding of a liquid silicone composition, comprising: means for providing a partial flow path for said liquid composition from a runner plate to a runnerless nozzle, a nozzle plate providing a supportive location for a runnerless nozzle and a cavity locating post; means for providing cooling to a runnerless nozzle heat tube using a cooling circuit, rigidly connected to said means for providing a partial flow path of said liquid composition from said runner plate to said runnerless nozzle, said nozzle plate providing a supportive location of said runnerless nozzle and said cavity locating post; means for providing secure alignment of a cavity block to said runnerless nozzle, rigidly attached to said means for providing said partial flow path for a liquid composition from said runner plate to said runnerless nozzle, said nozzle plate providing a supportive location of said runnerless nozzle and said cavity locating post; means for providing a path for circulating a cooling media around said heat tube, centrally embedded to said means for providing cooling to said runnerless nozzle heat tube using said cooling circuit; means for securing said runnerless nozzle to said nozzle plate; means for providing a flow path from said runner plate to said cavity, threadably inserted to said means for securing said runnerless nozzle to said nozzle plate, and frangibly inserted to said means for providing a partial flow path for said liquid composition from said runner plate to said runnerless nozzle, said nozzle plate providing a supportive location of said runnerless nozzle and said cavity locating post; means for providing cooling to said runnerless nozzle, tightly encompassing said means for providing a partial flow path from said runner plate to said cavity; means for providing a gate device to said runnerless nozzle and partially housing said runnerless nozzle seal, sealably assembled to said means for providing a partial flow path from said runner plate to said cavity; means for securing a runnerless nozzle gate tip to said runnerless nozzle, threadably fastened to said means for providing a gate device to said runnerless nozzle and partially housing said runnerless nozzle seal; means for providing mechanical engagement for said gate tip retainer; means for providing location and guide for a valve pin while creating a leakless seal, sealably inserted to said means for providing flow path from said runner plate to said cavity; means for providing shape for liquid composition; and means for providing thermal distribution in said cavity block, internally constructed to said means for providing shape for said liquid composition.
