Platen-mounted, post-mold cooling apparatus and method includes structure and/or steps for handling molded parts in an injection molding machine having a fixed platen, a moving platen, a core half, and a cavity half. A take off device coupled to the fixed platen is configured to remove molded parts from either the core half or the cavity half. A cooling device coupled to the moving platen is configured to cool the molded parts carried by the take off device. Preferably, the take off device extracts the just molded parts from the mold's core half and then moves linearly outboard of the mold halves. The subsequent movement of the moving platen to close the mold in the next molding cycle causes the cooling device's pins to engage the molded parts in the take off device part carriers. When the moving platen opens again, the molded parts are extracted from the part carriers by the cooling device pins. When the moving platen is fully open, the cooling device is rotated to eject the cooled parts from the machine.

Platen mounted post mold cooling apparatus and method

The present invention relates to a modular fluid distribution block having particular utility in a cooling system for the mold of an injection molding machine. The fluid distribution block of the present invention is characterized by a housing having a plurality of ports in fluid communication with each other and a plurality of feet. The feet have three orthogonally arranged bores machined therein to allow the fluid distribution block to be connected to another fluid distribution block, a plate for closing off a port and/or a fitting for allowing the fluid distribution block to be connected to another component such as a flexible hose. The fluid distribution block is preferably formed from a corrosive resistant material to avoid the problem of scaling. The manner in which the fluid distribution block is incorporated into a system for providing a mold with cooling fluid is also described.

Modular mold cooling system

The present invention relates to an injection molding machine having a novel key/slot arrangement for facilitating installation and removal of a central mold portion. The novel key/slot arrangement includes non-uniform width key elements on frame members which support the central mold portion and non-uniform width slots in side portions of the central mold portion for engaging the key elements. The machine further includes a novel rack/gear drive arrangement for insuring a proper positioning of the mold elements at all times.
