Abstract

A mold holder of an injection molding machine includes a base, several clamping blocks, and nuts. The base has cylindrical channels extending inwards from a lateral edge thereof, and trenches formed on an upper side; the elongated trenches are above, and in communication with, respective cylindrical channels. Each of the nuts has a cylindrical shape and a screw hole on a curved side thereof; the cylindrical nuts are fitted in the cylindrical channels, and bolts are tightly connected to other common nuts, the clamping blocks, and the cylindrical nuts so that a mold can be held on the base with the clamping blocks being pressed against it.

Claims

1. An improvement on a mold holder of a molding machine and structure of combination, comprising

a base having a plurality of elongated cylindrical channels extending inwards from a lateral edge thereof, and elongated trenches formed on an upper side;

the elongated trenches being above, and in communication with, respective ones of the cylindrical channels; and

,

a plurality of nuts, each having a cylindrical shape and a screw hole on a curved side thereof;

the nuts being fitted in the cylindrical channels for tight connection to bolts and clamping blocks used for holding a mold in position on the base.

2. The mold holder of a molding machine and structure of combination as claimed in claim 1, wherein outward ends of the elongated trenches is a distance from the lateral edge of the base.

3. The mold holder of a molding machine and structure of combination as claimed in claim 1, wherein the elongated trenches extend to the lateral edge of the base.
