48 primary references support a field guide of 57 components. Manufacturer catalogues, technical papers and training resources connect each explanation to further study.
The models are original parametric teaching assemblies. The main mould uses a declared 300 × 300 mm nominal stack with matched drafted surfaces, real bores and constrained motion. The machine uses a 30 mm screw in a 30.1 mm barrel bore. Threads, vents and material behaviour remain educational representations. They are not OEM CAD, production tooling drawings or simulation results.
The tooling, machine and cell explorers use the same detailed two-plate, two-cavity cold-runner mould, generated from one source model. Its 260 mm closed stack, 160 mm opening and 36 mm ejection determine the installed press geometry. Slides, lifters, sleeve ejection and a hot runner are separate reference exhibits. The machine uses a four-tie-bar toggle clamp, and the main robot is Cartesian. Other architectures are explained without implying identical hardware.
Section mode produces hatched cut surfaces on closed solids while preserving bores and internal passages. The mould cooling circuits are genuinely cross-drilled; coloured water volumes occupy those holes. Exploded views preserve component order and attached circuits. Mechanism tests check fixed link lengths, actual mounting and nozzle surfaces, pin alignment, slide and lifter constraints, clearances and shared strokes. The cell transfers the original cups and runner through measured grip contact to the actual conveyor surface, with reversible scrubbing and sampled rigid-body clearance checks. Cycle time and material-front motion are teaching sequences, not process or collision simulations.

Begin with the mould’s structural stack and material path. Then follow the machine’s screw and clamp. Connect the dryer, temperature controller and take-out robot to the production cell. Use a lab to test your intuition before opening the troubleshooting guide.
Terminology varies between mould shops and catalogue systems. “Backplate,” “backing plate,” and “clamping plate” can be used differently; identify the part by its position, load path and interfaces as well as its name.
