Gap correction mechanism and half nut fastening device of injection molding machine having same

Abstract

The present invention relates to a gap correction mechanism and a half nut fastening device of an injection molding machine having the same, wherein a surface contact with a fastening surface is made, and a gap existing on a fastening surface of a half nut is simultaneously removed easily, thereby transferring a uniform load. The present invention provides a gap correction mechanism for removing a gap with a fastening surface of a counterpart structure, the gap correction mechanism comprising: a fixing unit coupled to a fastening surface of each counterpart structure; a fastening piece screw-coupled with the fixing unit and inserted into the fixing unit; and a fixing member screw-coupled to the outer peripheral surface of the fastening piece so as to pressurize the fixing unit.

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...

Problems solved by technology

[0019] However, even with this conventional technology, the gap d between the connecting blocks 630, 630a and the connecting surfaces of the left and right split nuts 100, 200 cannot be completely removed, so there is still a gap between the split nuts. The problem that the fastening action cannot be performed accurately at the same time

[0020] In addition, since the fastening surfaces of the left and right split nuts 100, 200 and the connection blocks 630, 630a are only connected in the form of point contact at the positions of the bolts 640, 640a and the set screws 650, 650a, therefore, there are the following Problem: The load is locally transmitted at the contact positions of the bolts 640, 640a and the set screws 650, 650a between the above-mentioned connection blocks 630, 630a and the above-mentioned left and right split nuts 100, 200, and as a result, in the left and right The load transmitted when the side split nuts 100 and 200 are tightened at the same time cannot be evenly applied
