## Abstract

A machine base for an injection molding machine is equipped with an upper frame supporting at least a mold clamping device of the injection molding machine from below, two lower frames supporting the upper frame from below in a state of being in contact with a bottom surface of the upper frame, and a plurality of height adjusting mounts respectively attached to bottom surfaces of the two lower frames and configured to adjust the height of the injection molding machine.

## Claims

### Claim 1

A machine base for an injection molding machine, comprising:
an upper frame supporting the injection molding machine from below; and
a lower frame supporting the upper frame from below in a state of being in contact with the upper frame.

### Claim 2 (depends on 1)

The machine base for the injection molding machine according to claim 1, wherein:
the lower frame includes two lower frames; and
the two lower frames are arranged with a predetermined space and support the upper frame from below in the state of being in contact with the upper frame.

### Claim 3 (depends on 2)

The machine base for the injection molding machine according to claim 2, wherein:
the injection molding machine comprises a mold clamping device configured to open and close a mold and an injection device configured to inject melted resin into the mold; and
the upper frame supports at least the mold clamping device from below.

### Claim 4 (depends on 3)

The machine base for the injection molding machine according to claim 3, wherein:
the two lower frames are arranged along an opening/closing direction of the mold while providing a vacant lower region of the mold.

### Claim 5 (depends on 3)

The machine base for the injection molding machine according to claim 3, wherein:
the mold comprises a stationary mold and a moving mold;
the mold clamping device includes a stationary platen to which the stationary mold is attached, a moving platen to which the moving mold is attached, a rear platen, and a toggle mechanism configured to move the moving platen toward and away from the rear platen; and
of the two lower frames, one lower frame supports the upper frame in a range from a lower side of the rear platen to a predetermined position within a moving range of the moving platen, while another lower frame supports the upper frame on a lower side of the stationary platen.

### Claim 6 (depends on 3)

The machine base for the injection molding machine according to claim 3, wherein:
each of the upper frame and the two lower frames is provided with a plurality of first members extending along an opening/closing direction of the mold and a plurality of second members extending in a direction crossing the opening/closing direction of the mold and connecting the plurality of first members; and
each of the two lower frames supports the upper frame from below in a manner that the plurality of first members of the lower frame are in contact with the first members of the upper frame.

### Claim 7 (depends on 1)

The machine base for the injection molding machine according to claim 1, further comprising:
a height adjusting mount attached to a bottom surface of the lower frame and configured to adjust height of the injection molding machine.
