Apparatus and method for removing molded articles in uniform orientation

Claim 2

In an injection molding apparatus for continuously molding articles including a pair of relatively movable mold platens, each platen supporting a mold element cooperating to define a mold cavity, said platens cycling continuously through a cavity opening stroke and a cavity closing stroke, an improved device for receiving and dispensing molded articles in a uniform physical orientation comprising:

Claim 3

a receiving means carried by one of said platens, said receiving means being movable from a first position defining a release position to a second position defining a receiving position in proximity to a molded article retained on one of said platens, and a transfer means carried by said one platen responsive to relative motion between said platens for driving said receiving plate from said first position to said second position, said receiving means being but a single elongated channel having a predetermined cross-section mating with a chute having a similar cross-section.

Claim 4

a receiving means carried by one of said platens, said receiving means being movable from a first position defining a release position to a second position defining a receiving position in proximity to a molded article retained on one of said platens, and a transfer means carried by said one platen responsive to relative motion between said platens for driving said receiving plate from said first position to said second position, said receiving means being but a single elongated channel having a predetermined cross-section mating with a chute having a similar cross-section.

Claim 5

The apparatus of claim 1 in which one platen is fixed and the other platen is movable and the receiving plate is carried by the movable platen.

Claim 6

The apparatus of claim 1 in which one platen is fixed and the other platen is movable and the transfer means is carried by the movable platen.

Claim 7

The device of claim 1 in which one platen is fixed and the other platen is movable and the receiving means and the transfer means are both carried by the movable platen.

Claim 8

The device of claim 4 in which the transfer means includes at least one cam follower on the fixed platen cooperating with a cam fixed to said movable platen.

Claim 9

The device of claim 5 including fluid means for urging the cam follower into firm contact with said cam.

Claim 10

The apparatus of claim 1 in which said movable platen supports a chute device fixed at said release position, said chute providing a continuation of said receiving plate when said means is in the release position.

Claim 11

The device of claim 7 in which said receiving means is formed with an aperture and a communicating channel leading to a source of vacuum, said aperture in the proximity of a molded article when said receiving means is in said second or receiving position whereby a molded article thrust upon the receiving means is retained by vacuum applied through said aperture.

Claim 12

The device of claim 7 in which said movable platen supports a cover plate fixed at said release position in register with said chute which cooperates with said receiving plate at said release position to keep articles from tumbling.

Claim 13

The device of claim 7 in which said chute defines a first path generally parallel to said receiving plate curving to a second path generally perpendicular to said first path.
