A rotary injection molding apparatus and method for manufacturing products containing elastomeric material within multi-section single cavity molds. The apparatus includes a modular frame supporting an injection molding operation station having an injector assembly with a pressure sensitive nozzle assembly. The injector assembly is engaged with an extruder assembly at a check valve assembly. A mold servicer assembly is provided for assembly and disassembly of multi-section single cavity molds. A robotic arm assembly is supported on the modular frame and positioned for inserting and removing products or product components from disassembled molds. Finally; a rotating table is provided on the frame which has a plurality of work station positions supporting clamping assemblies for clamping single cavity molds around the periphery of the rotating table.

Rotary injection molding apparatus and method for use

A roll coater assembly system for application of a fluid material having a transport system with a part loading system, an application system, and a curing system for curing the material applied. The transport system is a continuous conveyor having a plurality of work stations movably supporting and transporting items to be processed to the application systems and curing systems, with the conveyors of the transport and loading systems having a single drive mechanism which operates both of the conveyors, such that the cylindrical items are provided to circumferentially located stations within and surrounding a cylindrical wheel of the part loading system which rotates to engage and move the cylindrical items into and out of the stations of the cylindrical wheel about a central axis of the cylindrical wheel and into the transport system conveyor by movement of the drive mechanism and respective conveyor synchronized by a control system.

Roll coater assembly system

The injection molding machine has an extruder for providing molding material, a cavity for retaining the molding material prior to injection into a mold, a plunger within the cavity to move the material out of the cavity, and a check valve. The check valve has separate means to permit the material to flow from the extruder to the cavity and from the cavity to an adjacent mold. By having separate flow channels for molding and recharging, the injection molding machine may be recharged on the fly.

Apparatus for injection molding

Discloses is an apparatus for injection molding permitting movement of the injection molding machine in multiple planes. The apparatus has a frame and an injection molding machine mounted within the frame. Located on both the frame and the injection molding machine are a plurality of interlocking rails and rail bearings. The movement of the rails in the rail bearings permits the injection molding machine to move relative to the frame. The frame is a two piece interlocking frame, the two pieces being capable of movement relative to each other.

Apparatus for injection molding in alternate planes

A modular injection molding machine has an extruder/injector assembly, a carriage assembly for carrying the extruder/injector assembly, a first clamping apparatus for holding an associated first mold, a main frame assembly which supports the first clamping apparatus and, a first adder module assembly. The first adder module assembly is selectively operatively connectable to the main frame assembly and is used to support a second clamping apparatus at any selectable laterally spaced distance. The carriage assembly selectively carries the extruder/injector assembly between the first and second clamping apparatuses. The preferred clamping apparatus has a first clamp assembly which is rigidly connected to an associated support member, a second clamp assembly which is movably connected to the first clamp assembly, a lower platen assembly which is operatively connected to the first clamp assembly, an upper platen assembly which is operatively connected to the second clamp assembly and, moving means for selectively moving the second clamp assembly. The first and second clamp assemblies form a collapsible C frame support structure. To add an adder module to a modular injection molding machine, first a base plate is positioned at any selectable laterally spaced distance from a bottom plate. Next, a front plate is placed on a front shelf on the base plate. A back key is then installed, being received within a back key slot on the bottom plate and within a back key slot on the base plate. After that, a tie bar is connected to the bottom plate, the first plate, the base plate and the front plate. A front key is then installed, being received within the key slot of the first plate and within a key slot of the front plate. Finally, a second clamping apparatus is connected to the front plate.
