发明名称 Injection mold having a rotatable sprue member
摘要 An injection mold typically defines multiple cavities. A mold gate is provided which comprises a rotary spherical member having a sprue conduit extending transversely therethrough. Highly accurate sequential molding of multiple cavities can be achieved in this manner, as well as other advantages. Also, this arrangement permits a linear, straight sprue conduit which is free of any sharp turns.
