摘要： An injection mold for use with a molding press has four mold levels in axially stacked relation, permitting a substantial doubling of output for a given size of press as compared with a back-to-back two level stacked mold. The mold feeder flow path extends axially from the injector head to a flow distribution block located at the centre of the stacked mold block series. The centrally located distribution block is connected, in sealed relation with the injector head, being axially displaceable therefrom in continuing sealed relation upon the opening of the mold. A drool prevention valve system, located at two of the mold interfaces, to preclude drooling of fluid plastic stock upon opening of the molds includes pressure fluid actuators for operating the valves, wherein the pressure fluid may comprise the fluid plastic stock. The valve system also includes a depressurizing valve provision, wherein, upon opening of the mold interfaces the stock distribution passages are substantially depressurized, to thereby reduce any tendency to drool. The mold includes axial adjustment means to compensate for differential variations in overall mold length within the press, due to changes in effective mold temperature.

摘要： A multi-level stacked mold having at least two and as many as four levels of cavities has a stock distribution mold block centred axially of the stacked mold blocks, the axially extending stock inlet passage to the distribution block connecting with radially off-set stock transfer passages that cross the axially openable mold block interfaces, into the adjoining mold blocks. These openable stock transfer passages, are each provided at their respective, non-encapsulated, radially off-set, opening interfaces with a valveless anti-drool arrangement. The mold flow passage system is subject to continual, extreme, thermal cycling and cyclical mechanical loading, during the repeated opening-and-closing cycles of the mold. Each separable anti-drool sealing interface has a relatively axially displaceable portion extending to bridge the initial gap opening between adjacent mold blocks and serving as an expansible piston means. This extension of the displaceable "expansible piston means" portion is pressure responsive and serves to increase the internal volume of the adjacent transfer passage, while permitting equalizing the pressure of stock in the passage to atmospheric pressure, thus reducing the likelihood of the drooling of liquid plastic into the opening interspace, or the induction of atmospheric air into the flow passages.

摘要： A motion transfer mechanism has an elongated track upon which ride transfer mechanisms, to translate relative movements of the track into precise actuation of one or a plurality of transfer mechanisms. The track is of substantially unlimited length, in relation to the machine with which it is used, such as the press of a stacked injection mold, so as not to limit access to, or the range of motion of the press or other machine. The transfer mechanisms each rides upon the track, such that they can freely traverse its full length. The track has one or more spiral portions in its length, to translate relative longitudinal displacement into rotational movement. The angle of spiral can be varied, with local changes in angle, on order to achieve desired rates of acceleration, deceleration and periods of dwell in the operation of the output mechanism. The transfer mechanisms and the track mounting each have a simple enabling and disabling mechanism, which may be interconnected by a simple, manually operable, bang-bang hydraulic control, to enable an operator to effect operation or disablement of the system with a single hand motion. The system may be used with high cycle processes such as an injection mold, the track and motion transfer portions of the system being comprised exclusively of simple, robust, low stress mechanical components of extreme reliability, without power cylinders or other prime movers or limit switches, relays or other electronic components that collectively diminish system reliability. In the case of use of the system to introduce product take-off devices, such as suction cups between the open platen faces of a mold, the system may be secured in "strap-on" relation to the sides of the respective components of the mold, to generate precise in-and-out actuation of the product handling devices between the mold interfaces during the ejection portion of the molding cycle in response to the normal cyclic movements of the mold.
