Abstract
A support frame of a machine base includes a first element to be joined to the upper or lower end face of a vertical support column of the machine base and extending in the horizontal direction, and a second element spaced from the first element on the opposite side from the support column and extended in the horizontal direction. The end face of the support column joined to the first element is formed with one or more first protrusions which extend to reach the second element and join to it.
Claims16
A machine base of an injection molding machine that supports at least one of a clamping unit and an injection unit, comprising:
- a support frame extending in a horizontal direction;
- and
- a support column extending in a vertical direction intersecting the horizontal direction,
- wherein the support frame includes:
- a first element to be joined to an upper or lower end face of the support column, and extending in the horizontal direction;
- a second element spaced from the first element on an opposite side from the support column and extended in the horizontal direction;
- and
- a third element connecting the first element and the second element, and
- wherein the second element includes a first surface and a second surface arranged in the vertical direction, the second surface being more toward the opposite side than the first surface,
- either the upper or lower end face of the support column is joined to the first element, and the joined end face of the support column is formed with one or more first protrusions which extend through a through hole in the first element to reach a through hole in the second element and
- a distal end of the one or more first protrusions is located between the first surface and the second surface in the vertical direction and is welded to the second element through a second-surface-side opening of the through hole in the second element.

- and
- a third element connecting the first element and the second element, and
- wherein the second element includes a surface being more toward the first element with respect to the vertical direction, and an outer-side surface in a width direction that is perpendicular to the horizontal direction and the vertical direction, of an upper end face and a lower end face of the support column, an end face joined to the first element of the support column is provided with one or more first protrusions extending in the vertical direction and being welded to the second element, and
- a distal end of the one or more protrusions is in contact with the surface or the outer-side surface.
