Description

technical field

[0001] The present invention relates to a gap correction mechanism and a split nut fastening device for an injection molding machine provided with such a gap correction mechanism. Surface contact, so that the gap between the above-mentioned fastening joint surface and one side of the above-mentioned gap correction mechanism is removed, so that the simultaneous clamping action of opening and closing nuts can be accurately performed. Split nut fastening device for forming machine. Background technique

[0002] Next, a split nut fastening device for an injection molding machine according to the prior art disclosed in Patent Document 1 will be described with reference to the drawings.

[0003] Such as Figure 7 and Figure 8 As shown, the conventional split nut fastening mechanism includes a left split nut 100 and a right split nut 200 . The above-mentioned left side split nut 100 and right side split nut 200 are formed in the form of being divided into two sp...
