ABSTRACT:

TECHNICAL FIELD
The present invention generally relates to systems for collecting parts from injection molding machines, and in particular to a system that provides for easy and quick changing of devices for receiving molded parts and/or runners.
BACKGROUND ART
A typical machine for injection molding of plastic parts is shown in FIG.
1
. The machine
10
includes a suitable frame
12
which carries a fixed platen
14
and a movable platen
16
. The movable platen
16
is carried by a plurality of support rods
18
for movement toward and away from the fixed platen
14
by a suitable hydraulic mechanism. Conventional mold members
20
and
22
are mounted in the customary manner to the platens
14
and
16
, respectively, for moving towards and away from one another with the platens. The mold members
20
and
22
include complimentary mold cavities (not shown) into which liquid plastic is injected from a conventional ram-type injection mechanism
24
.
Generally located below the platens
12
,
14
and defined within the frame
12
of the molding machine
10
is an open horizontal passage
26
for receiving a freestanding conveyor or the like (not shown). Also, the passage
26
is in communication with an opening
28
positioned generally below the platens
12
,
14
for allowing molded plastic parts to fall from the mold members
20
,
22
and into the passage
26
when the mold members
20
,
22
are separated from each other.
The type of freestanding receiving device positioned underneath the molding machine platens
14
,
16
and within the passage
26
typically varies as the mold members
20
,
22
are changed. The swapping of freestanding receiving devices is a time consuming procedure since these devices are separate from the molding machine
10
and thus must be adapted to stand at the desired position and attitude within the passage
26
.
SUMMARY OF THE INVENTION
Generally, the parts collection system of the present invention includes a pair of support tracks for mounting to the frame of an injection molding machine having a pair of platens adapted to receive mold members. Adjustably mounted to the support tracks are a pair of retaining beams for suspending a device adapted to receive parts dropped from the mold members.
