Abstract

A mold device includes a frame that is a vertical wall having a first surface that is a vertical surface to which a holding mechanism is mounted and supported only by the first surface. A fixed mold base supporting a fixed mold, one surface thereof fixed to the first surface of the frame, and a mobile mold base supporting a mobile mold, the mobile mold base held by the holding mechanism so that the mobile mold base moves closer to and away from the fixed mold base. The holding mechanism includes a rail fixed to the first surface, and a guide fit on the rail in such a way that the guide moves on the rail while the guide is fixed to the mobile mold base. The mobile mold base is supported by the holding means without using a tie bar, and cantilevered on the first surface via the holding mechanism.

First claim

What is claimed is:

1. A mold device comprising:
a frame that is a vertical wall having a first surface that is a vertical surface of the frame;
a holding means mounted to, and supported only by, the first surface of the frame;
a fixed mold base for supporting a fixed mold, one surface of the fixed mold base being fixed to the first surface of the frame; and
a mobile mold base for supporting a mobile mold, the mobile mold base being held by the holding means so that the mobile mold base moves closer to and away from the fixed mold base;
wherein
the holding means comprises a rail fixed to the first surface of the frame, and a guide fit on the rail in such a way that the guide moves on the rail while the guide is fixed to the mobile mold base,
the mobile mold base is supported by the holding means without using a tie bar, and
the mobile mold base is cantilevered on the first surface of the frame via the holding means.

2. The mold device according to claim 1 , wherein
the fixed mold and the mobile mold includes a positioning key, the positioning key being a pair of a positioning recess and a positioning projection, one of the positioning recess and the positioning projection being formed in the fixed mold and another one of the positioning recess and the positioning projection being formed in the mobile mold.

3. The mold device according to claim 2 , wherein
the one of the positioning recess and the positioning projection is formed in a surface of the fixed mold that is opposite from a surface of the fixed mold that is supported by fixed mold base, and the another one of the positioning recess and the positioning projection is formed in a surface of the mobile mold that opposite from a surface of the mobile mold that is supported by the mobile mold base.

4. The mold device according to claim 1 , wherein
a machined surface is formed in the first surface of the frame, and
the mobile mold base is provided with a dimensional reference line formed at a position relative to the machined surface.

5. The mold device according to claim 1 , further comprising:
driving means for moving the mobile mold base, wherein
the driving means moves the mobile mold base by pressing a center of the mobile mold base.

6. The mold device according to claim 1 , wherein
the frame is disposed on a side surface of the mobile mold base in the horizontal direction.
