    Referring to Figs. 1 and 2, an injection molding machine 100 includes a base plate 102, a stationary plate 104 fixed on the base plate 102 for holding a first mold section 108a, and a movable plate 106 for holding a second mold section 108b. The movable plate 106 is slidably supported on a plate slide surface 110 fixed on the base plate 102 and movable toward and away from the stationary plate 104 along a machine axis 112. The movable platen is generally movable along the platen slide 110 between a closed mold position (FIG. 2), with the movable platen being positioned closest to the stationary platen, and a maximum daylight position (FIG. 1), the movable platen being away from the stationary plate is disposed away through 'a plate opening 114. Translation of the movable plate 106 can be effected by a plate actuator 107. In the illustrated example, the plate actuator 107 includes a ball screw 107a coupled to the movable plate 106 through a ball nut 107b and driven by a plate actuator motor 107c.
    The slide plate 110 may include a pair of plate rails 134 disposed on laterally opposite sides of the base plate 102 and extending parallel to the machine axis 112. In the example shown, the movable plate 106 includes plate bearing shoes 136 (FIG. 2) fixed on the movable plate 106 and slidably engaged in the plate rails 134.
    The machine 100 may further include a plurality of stiles 126 extending parallel to the machine axis 112 and between the stationary and movable plates 104, 106 for axially clamping the mold sections 108 during an injection cycle. In the example depicted, the machine 100 includes a front lower spar 126a and a rear lower spar 126b disposed transversely of each other (by a lateral spacer spar 128-FIG. 3) along opposite sides of the machine 100. The front lower spar 126a is in the example depicted towards the user side 130 of the machine 100, and the rear lower spar 126b is disposed toward the non-user side 132 of the machine 100 with the machine axis 112 laterally interposed between the front and rear lower bars 126a, 126b. The machine 100 may further include a front upper rail 126c disposed vertically above the front lower rail 126a and a rear upper rail 126d disposed vertically above the rear lower rail 126b.
    In the example depicted, the machine 100 further includes mold center section 108c axially disposed between the first and second mold sections 108a, 108b. An injection unit 116 is supported on the base plate 102 and injects resin (or other injection component) into mold cavities formed by the mold sections 108 when the mold is closed.
    Referring again to Figure 1, the machine 100 further includes a carriage support structure 140 which slidably supports a stack mold carriage 142 for holding the mold center section 108c. The stack mold carriage 142 is translatable parallel to the machine axis 112 between an extended carriage position generally corresponding to the closed mold position (FIG. 2) and a retracted carriage position generally corresponding to the open mold position (FIG. 1). The retracted carriage position is axially separated from the extended carriage position by a carriage stroke length 144.
    With continued reference to Figure 4, the carriage support structure 140 includes a beam pair 148 which is removably fixed relative to the base plate. The beams 148 extend parallel to the machine axis 112 and are arranged laterally to one another. The beam pair 148 includes a first beam 148 a disposed toward the user side 130 of the machine 100 and a second beam 148 b disposed toward the non-user side 132 of the machine 100.
    Each of the beams 148a, 148b is positioned laterally inward of the respective lower beam 126a, 126b. Each of the beams 148a, 148b has a beam length 150 extending axially between opposite ends 152, 154 of each beam 148 (Figure 5). The beam length 150 of each beam 148a, 148b is shorter than the disk aperture 114 and longer than the carriage stroke length 144 in the example depicted. Each beam 148 may be of integral one-piece construction. In the example depicted, each beam 148 is a unit length of steel having a generally rectangular cross-sectional profile.
    The first end 152 of each beam 148 may be detachably secured to the stationary platen 104. In the example depicted, first end bolts 156 secure the first end 152 of the beam 148 to a bottom surface of the stationary platen 104. The second end 154 of each beam 148 can be removably secured to the base 102 of the machine 100. In the example shown, second end plugs 158 secure the second end of each beam on an upwardly directed step surface 160 of the base plate (Figure 6).
    With further reference to Figure 4, the carriage support structure 140 has a structural width 162 which is generally defined by the lateral distance between lateral outer surfaces 164a, 164b of the first and second beams 148a, 148b. The structural width 162 is less than the lateral spar spacing 128 in the example depicted. This may facilitate removal of the carriage 142 with the beams 148 by being lifted together between the beams 126. In the example shown, the carriage support structure 140 is free of cross structural members. which interconnect the first and second beams 148a, 148b. In some examples, such transverse structure members may be provided, for example at one or both ends of the beams.
    The beams 148 have lateral inner surfaces 166 aligned with each other, which are arranged laterally to each other to define a beam aperture 168. The stack mold carriage 142 has an axial dimension 169 which is smaller than the beam opening. This may facilitate a way of removing the carriage 142 by rotating the carriage (about 90 degrees) and lowering the carriage between the beam opening 168.
    With continued reference to FIG. 4, a carriage actuator 170 is coupled to the stack mold carriage 142 for translating the stack mold carriage 142 along the machine axis 112 toward and away from the stationary platen 104. In the example depicted, the carriage actuator 170 includes a propeller 172 which The carriage pivot 170 further includes a connection 176 connecting one end of the propeller 172 to the movable plate 106 and another connection connecting an opposite end of the propeller 172 to the stationary plate 104 connects. In the example depicted, the propeller 172 is positioned at a level just below the lower surface of the beam 148. Each link 176 is disposed at generally the same height as, and outwardly from, the outer surfaces 164 of a respective beam.
    The beams 148 may support a pair of stack mold carriage rails 180 along which the stack mold carriage 142 is slidable. In the example depicted, a first rail 180a is attached to the first beam 148a, and a second rail 180b is attached to the second beam 148b. The stack mold carriage 142 in the example depicted is equipped with carriage shoes 182 which slidably engage the carriage rails 180. In the example shown, the stack mold carriage rails 180 are positioned separately from and laterally inwardly toward the plate rails 134. The carriage rails 180 are also positioned in the illustrated example at a height which is below the height of the plate rails 134.
    Referring now to FIGS. 8 and 12, the machine 100 further includes an optional fluid manifold 186 for providing at least one fluid to the mold center portion 108c. The manifold 186 may include at least one inlet port 188 connectable to a fluid source through a flexible inlet conduit 190, and at least one outlet port 192 connectable to the mold center portion 108c through an outlet conduit. A return line may be connected to at least one return port 194 of the manifold 186 for reflux of fluid from the mold center section 108c to the manifold 186, and a flexible output line 196 connected to an outlet port 198 of the manifold 186 may further return the fluid from the manifold 186 back to Conduct fluid source.
    In the example depicted, the manifold 186 includes: an inlet port 188 for receiving a mold cooling fluid (eg, water) from a source; two outlet ports 192a, 192b for distributing the cooling fluid from the inlet port 198 to opposite sides of the mold center section 108c; two return stubs 194a, 194b for receiving the cooling fluid flowing back from the mold center portion 108c; and an exit port 198 for directing the cooling fluid away from the mold center section 108c back to the fluid source.
    The manifold 186 is removably mounted in an access position (Figures 8 and 9) with fluid communication between the inlet port 188 and the mold center portion 108c provided by exit conduits attached to the outlet port 192 and a loading position (Fig. 10 and 11), wherein the flexible input line 190 may remain connected to the at least one
    Inlet port 188, and the outlet ports 192 are in fluid isolation from the mold center section 108c.
    In the access position, the manifold is removably secured to the carriage 142 by a carriage distribution mounting structure 202 (see FIGS. 8 and 12). In the example depicted, the carriage distribution mounting structure 202 includes a bracket 204 having an arm 204a secured by fasteners 206 to an upper surface of the carriage 142 and another arm 204b secured to an inner surface 186a of the manifold 186 by fasteners 208 ,
    In the loading position, the manifold is detachably secured to the machine base by a machine base plate mounting structure 210 (Fig. 10). In the example depicted, the machine base mounting structure 210 includes a pair of fasteners 212 that pass through openings 214 in a side wall of the base plate 102 and snap threaded holes 216 in an outer surface 186b of the manifold 186 (see FIGS. 9 and 12).
    To facilitate movement of the distributor between the access and loading positions, the carriage 142 is optionally slidable along its travel axis to a dispenser transfer position (Figure 12). When the carriage is in the transfer position, the distributor has a common axial position in both the access and loading positions; and the carriage distribution mounting structure 202 and the machine base distribution mounting structure 210 are both aligned with the manifold 186. In the example depicted, when the manifold 186 is in the access position and the carriage 142 is in the transfer position, the outer surface 186b of the manifold 186 is laterally spaced from a front surface 217 fixed to the base by a recess 215 (FIG. 9). Moving the distributor to the loading position corresponds to a lateral movement of the distributor, closing the recess 215. The mounts of the machine base plate attachment structure may, in the example depicted, be threaded into the threaded bores 216 of the manifold 186 before the mount 204 of the carriage manifold attachment structure 202 is released.
