Abstract

An apparatus for taking out a molded product, which is capable of taking out a resin molded product in fewer steps than ever, includes: a transverse frame disposed above a resin injection molding machine to extend in a transverse direction which is orthogonal to a longitudinal direction; an orthogonal frame supported by the transverse frame so as to be movable at least in the transverse direction; a vertical arm provided at the orthogonal frame so as to be movable up and down at least in the vertical direction; and a holding member provided at a distal end portion of the vertical arm to hold a resin molded product formed by the resin injection molding machine. The vertical arm is disposed so as to be inclined such that the axis line of an elevating shaft of the vertical arm forms an acute angle with respect to a perpendicular extending in the vertical direction.

Claims

1. An apparatus for taking out a molded product, comprising:

a transverse frame disposed above a resin injection molding machine to extend in a transverse direction that is orthogonal to a longitudinal direction defined as a direction in which a molding die of the resin injection molding machine is opened and closed;

one or more orthogonal frames supported by the transverse frame so as to be movable at least in the transverse direction;

one or more vertical arms provided respectively at the one or more orthogonal frames so as to be movable up and down at least in a vertical direction; and

one or more holding members provided respectively at distal end portions of the one or more vertical arms to hold a resin molded product formed by the resin injection molding machine, wherein

the one or more vertical arms are disposed so as to be inclined such that axis lines of respective elevating shafts of the one or more vertical arms form an acute angle with respect to a perpendicular extending in the vertical direction.

2. The apparatus for taking out a molded product according to claim 1, wherein:

the one or more orthogonal frames include two orthogonal frames;

the one or more vertical arms include two vertical arms;

the transverse frame is provided with the two orthogonal frames configured to be separately movable; and

the two vertical arms are disposed respectively at the two orthogonal frames.

3. The apparatus for taking out a molded product according to claim 1, wherein

the one or more orthogonal frames are movable in the longitudinal direction with respect to the transverse frame.

4. The apparatus for taking out a molded product according to claim 1, wherein

the one or more vertical arms are respectively provided at the one or more orthogonal frames so as further to be movable in the longitudinal direction.

5. The apparatus for taking out a molded product according to claim 1, further comprising:

a longitudinal frame extending in the longitudinal direction, wherein

the transverse frame is supported by the longitudinal frame so as to be movable in the longitudinal direction.

6. The apparatus for taking out a molded product according to claim 1, wherein

the one or more vertical arms are respectively provided at the one or more orthogonal frames such that the acute angle is changeable.

7. The apparatus for taking out a molded product according to claim 2, wherein

the two vertical arms respectively provided on the two orthogonal frames are inclined such that the axis lines of the respective elevating shafts of the two vertical arms may cross each other on a side on which the resin injection molding machine is located.

8. The apparatus for taking out a molded product according to claim 7, wherein:

the resin injection molding machine comprises a fixed mold, a movable mold disposed so as to be movable with respect to the fixed mold, and an intermediate movable mold located between the fixed mold and the movable mold and disposed so as to be movable with respect to the fixed mold and the movable mold;

the resin injection molding machine is configured to form a resin molded product between the fixed mold and the intermediate movable mold and to form another resin molded product between the intermediate movable mold and the movable mold; and

the resin molded product formed between the fixed mold and the intermediate movable mold is held and taken out by one of the two holding members provided on one of the two vertical arms, and the resin molded product formed between the intermediate movable mold and the movable mold is held and taken out by the other of the two holding members provided on the other of the two vertical arms.

9. The apparatus for taking out a molded product according to claim 2, wherein

the one or more orthogonal frames are movable in the longitudinal direction with respect to the transverse frame.

10. The apparatus for taking out a molded product according to claim 2, wherein

the one or more vertical arms are respectively provided at the one or more orthogonal frames so as further to be movable in the longitudinal direction.

11. The apparatus for taking out a molded product according to claim 2, further comprising:

a longitudinal frame extending in the longitudinal direction, wherein the transverse frame is supported by the longitudinal frame so as to be movable in the longitudinal direction.

12. The apparatus for taking out a molded product according to claim 2, wherein
