ABSTRACT:
An improved injection molding apparatus for molding parts of thermosetting plastic material. First and second mold portions which together form a mold cavity at their molding surfaces are heated to allow thermosetting plastic material to set within the mold cavity when under pressure. A fluid distribution member comprises a manifold having an inlet port, two or more spaced outlet ports and a passage interconnecting the inlet port with the outlet ports guides the flow of plastic material therein. The manifold is cooled and includes a first manifold section disposed within a channel formed at the upper surface of a second manifold section such that the interconnecting passage is formed by a first wall portion of the first manifold section and a second wall portion of a second manifold section within the channel. The first and second manifold sections are separable to permit access to the passage to permit cleaning thereof. Two nozzle units each including a nozzle are secured within bores extending through the first mold portion by the second manifold section to conduct the flow of viscous plastic material from the outlet ports to the mold cavity. The first manifold section is secured to an upper support member of a support structure to move therewith and the second manifold section is secured to the first manifold portion so that the interior of the interconnecting passage and the second guide section are accessible when the upper support member is moved relative to the first mold portion.
