Closure unit on an injection molding machine with a rotary platform for multi-stage molding has four main tie bars and an additional tie bar near the rotary tool axis

摘要

The rotating plate lies behind or between two tool halves(11,12) mounted on platens connected by four conventionally arranged tie bars(14-17) and an additional tie bar(19) is located close to the axis of the rotary platform. An Independent claim is made for a process for injection molding components with several components using an injection machine with a rotary table. Non-injectable components, e.g. inserts, are fed to the table in one position and the table rotated to another position in which plastic is injected onto the insert.
