摘要： Each of the two sections of a separable mold for a giant plastic article includes a box having a contoured wall as one end face. The giant article is molded in the cavity defined by the pair of contoured walls. Each contoured wall is thin, heat conductive, and of low specific heat. A plurality of conduits on the rear face of each contoured wall direct the flow of heat transfer fluid to regulate the temperature of a zone of the contoured wall. A relatively high density cellular polyurethane serves as an insulating foundation between the rear face of a contoured wall and the plate of the box and also provides support for the contoured wall. A relatively thin layer of silicone rubber or like material is provided between the cellular polyurethane and each contoured wall. The contoured wall can undergo thermal expansion or contraction throughout or in selected zones without losing its bond to such cellular foundation. Floating connectors associate the contoured walls with frame members of the box, whereby relative thermal expansion of the box independently of the contoured wall is possible.

摘要： Split molds are mounted upon a plurality of platens having parallel faces reciprocating within the reciprocating linear movement of clamping means in an injection molding machine. Each mold cavity is filled through one or more nozzles extending from a fixed manifold portion of the machine, each nozzle having a tip at least intermittently fitting against a nozzle seat. Length adjustment means are provided for each nozzle, whereby the molding machine is operable at a plurality of temperatures, while still having a reciprocatingly retractable leakproof fit between certain nozzle tips and their nozzle seats.

摘要： PROGRAMMING, AND/OR DIFFERENTIAL PRESSURE PROGRAMMING FOR DIFFERENT ZONES OF THE ARTICLE. VARIOUS SUPPLEMENTAL AND/OR OPTIONAL FEATURES ARE DISCLOSED.
GIANT SIZED PLASTIC ARTICLES ARE MASS PRODUCED WITH AUTOMATION BY LOW PRESSURE INJECTION MOLDING. AN ARTICLE IS DESIGNED TO ACHIEVE THE ULTIMATE ENGINEERING PERFORMANCE OF THE INTERNAL STRUCTURE IN RELATION TO ITS EXTERNAL SHAPE, THUS PROVIDING ZONES IN WHICH THE INTERNAL STRUCTURE IS DIFFERENT FROM OTHER ZONES, ANDSUCH DIFFERENCES ARE IMPARTED BY THE CONTROL OF THE MOLDING PROCESS. THE PROPORTIONS OF GAS AND MOLTEN PLASTIC ARE CAREFULLY CONTROLLED PRIOR TO THE ACCUMULATION OF THE FEED IN A BATCHING DEVICE. A SHOT OF FEED FLOWS THROUGH A DISTRIBUTION SYSTEM INTO A STRUCTURIZER MOLD HAVING CONTOURED WALLS OF LOW SPECIFIC HEAT AND HAVING HEAT TRANSFER MEANS PERMITTING DIFFERENTIAL PROGRAMMING OF THE TEMPERATURE OF DIFFERENT ZONES. BEFORE THE ARTICLE HAS SOLIDIFIED IN THE STRUCTURIZER MOLD, THE DESIRED DIFFERENCES IN INTERNAL STRUCTURE ARE IMPARTED BY REASON OF THE DIFFERENTIAL TEMPERATURE-

摘要： Molds are produced by providing a master of relatively inexpensive material, preferably wood. The wood is coated with a material which will have the texture and dimensions of the end product to be produced. The coating material must be inert to a plating solution and must be conductive to permit deposition of the plating solution thereon. The master thus produced is electroformed to provide a metallic envelope of copper, nickel, or mixtures thereof thereabout. A box, open at one end, including a rear plate and peripheral frame members is provided for each contoured wall. Wax rods are mounted on the electroformed envelope. The wax rods communicate with the ends of metal tubing. A layer of silicone rubber or similar material is applied over the wax rods and the ends of the tubing. The wax rods are melted thus forming heat transfer conduits. An insulating foundation of polymethane is foamed in place between the rear face of the boxes and the rear face of the contoured walls. Thereafter, the electroformed envelope is severed about its periphery and the mold halves are removed for use with low pressure injection molding apparatus. Floating connectors associate the contoured walls of the mold with the frame members of the box so that relative thermal expansion of the box independently of the contoured walls is possible.
