Embodiment Construction

[0009] The middle mold tightening device of the present invention can be further described through the following drawings and implementation.

[0010] As shown in Figure 1: the middle mold fastening device of the present invention, it is to divide the original integral set screw into two parts by the outer screw (1) and the tight rod (3), the outer screw (1) and the The tightening rods (3) are connected by connecting screws (2), and the connecting screws (2) are left-handed screws.

[0011] When working, put this middle mold fixing device into the middle mold screw hole on the turntable, rotate the outer screw (1), and the outer screw will push the tightening rod (3) into the groove of the middle mold gradually, and tighten The surface contact between the fixed rod and the groove of the middle mold avoids the coaxiality error between the middle mold and the middle mold hole, so that the coaxiality between the middle mold and the middle mold hole is guaranteed, and the fastenin...
