The existing chinese patent publication No. CN201821042755.8 discloses a self-tapping thread insert, which comprises a hollow cylindrical thread insert body, wherein the thread insert body is provided with internal and external threads, one end of the thread insert body is provided with three cutting holes for cutting, the cutting holes are radially formed along the thread insert body, the thread insert teeth-shaped side surface of the thread insert body on the same side as the internal thread of the thread insert body is composed of a thread insert teeth bottom side surface located at the bottom of a tooth and a thread insert teeth top side surface located between the top of a tooth and the thread insert teeth bottom side surface, and the included angle between the thread insert teeth bottom side surface and the axis of the thread insert body is smaller than the included angle between the thread insert teeth top side surface and the axis of the thread insert body.
However, in the working process of the mold clamping mechanism of the injection molding machine, a plurality of screw holes for pressing the mold are arranged on the head plate and the second plate of the injection molding machine, and the situation that the screw holes slip threads is generated sometimes after the injection molding machine is used for a period of time. The existing self-tapping screw sleeve is generally consistent in upper and lower diameters, and subsequent maintenance and screw hole expansion are not convenient enough. Therefore, a need exists for a mold locking bolt bushing that solves the above problems.
SUMMERY OF THE UTILITY MODEL
The utility model provides a thin cover of mode locking bolt to the not enough of prior art existence, concrete technical scheme as follows:
the utility model provides a mode locking bolt thin sleeve, the bolt thin sleeve includes the body, the body shape is hollow cylinder, the body surface is equipped with the external screw thread, circumference is equipped with the internal thread in the body, body surface one end is provided with arc portion, the body passes through arc portion and is connected with heavy-calibre portion, arc portion and body forge into one.
As an improvement of the technical scheme, the top end of the large-caliber part is provided with an annular groove.
As an improvement of the above technical solution, the large-diameter portion is cylindrical, the inner circumference of the large-diameter portion is aligned with the inner circumference of the body, the radius of the bottom surface of the large-diameter portion is greater than that of the bottom surface of the body, and the center of the bottom surface of the large-diameter portion is vertically symmetrical to that of the bottom surface of the body.
As an improvement of the technical scheme, one end of the body, which is symmetrical to the arc-shaped part, is provided with a notch.
Compared with the prior art, the utility model, its technical effect as follows:
the utility model relates to a mode locking bolt thin sleeve, the body passes through the arc portion and connects big mouth of a river portion, and the one end that the bore is little is installed in advance during the installation, when waiting to maintain, takes off the swivel nut, and the bottom hole is big outside inside and small inside, makes things convenient for staff's later stage reaming to made things convenient for secondary maintenance; through setting up the annular groove, the annular groove inner ring sets up various shapes as required to be used for joining in marriage the nut of contract shape and fix, thereby install.
