  • Patent number: 4634366
    Abstract: An injection molding machine includes a platen having a plurality of regularly spaced mold element-receiving chambers adapted to receive any of a number of various mold elements substantially wholly within the stationary platen. A hot manifold system is included between the stationary platen and a plastics injector unit, which includes a plurality of blocks independently coupled to the fixed platen, each block having channels through which the plastics material can flow, the channels of adjacent blocks being coupled by a coupling unit. The machine is particularly designed for quick inexpensive mold changes, and has particular utility in laboratory testing of mold designs and small low-capacity production in satellite plants.

  • Patent number: 4622001
    Abstract: A cavity member is disclosed for use in an injection molding machine. The cavity member has one portion which includes a molding surface for forming the molded article and a second portion for reducing heat transmission to the first portion. The second portion forms a cap on the nozzle end of the cavity member and includes an aperture aligned with the gate of the cavity member so as to permit plastic from the nozzle of an injection molding machine to enter into the mold. The cap includes channels which can cooperate with pockets in the nozzle end of the second portion for liquid cooling. The nozzle is spaced from the cap by a short distance to provide a thermal break which break can be filled with plastic from the injection molding unit to provide further insulation.
