Detailed Description
The utility model is further described below with reference to specific examples:
a novel stud bolt comprises a first thread section 1 and a second thread section 2, wherein the first thread section 1 is used for connecting a wall plate 8 of an injection molding machine, and the second thread section 2 is used for installing a pressure plate 7; as shown in fig. 1 and 3, a threaded hole is formed in the injection molding machine wallboard 8, and the first thread section 1 is screwed into the threaded hole and connected with the injection molding machine wallboard 8 by rotating the novel stud; a through hole is also formed in the pressing plate 7 and is matched and connected with the second thread section 2, and a nut member 6 for limiting and fixing is also arranged above the pressing plate 7; the length of the second thread section 2 is about three times that of the first thread section 1, the second thread section 2 is matched with the height of the pressure plate 7, the first thread section 1 is matched with the thickness of the wall plate 8 of the injection molding machine, and therefore the clamping height of the mold is adapted; the user can select the stud bolts with different lengths according to actual sizes.
A middle hexagonal section 3 is arranged between the first thread section 1 and the second thread section 2, and one end of the middle hexagonal section 3 is provided with a circumferential boss 4 extending outwards. Referring to fig. 1 and 2 in particular, the central hexagonal section 3 is used for a user to apply force, and the user can set a wrench on the central hexagonal section 3 to drive the novel stud bolt to rotate; the circumferential boss 4 is circular, the upper end face of the circumferential boss 4 is an arc face and is connected with the outer surface of the middle hexagonal section 3, the lower end face 41 of the circumferential boss 4 is a horizontal plane, and the area of the lower end face 41 is far larger than the cross-sectional area of the first thread section 1; in the continuous downward screw in of first screw thread section 1 during injection molding machine wallboard 8, terminal surface 41 constantly removes to injection molding machine wallboard 8 down, and final butt is in on injection molding machine wallboard 8's the face, this novel stud is difficult to the downwardly rotating this moment, the suggestion the user installs and targets in place to play and prevent the too dark purpose of bolt installation, avoided well hexagonal section 3 to in injection molding machine wallboard 8's threaded hole, damage the screw thread in the threaded hole.
