Description

Technical Field

[0001] The utility model relates to the technical field of mold accessories, in particular to a concave-convex positioning and fastening ring of a mold oil cylinder. Background Art

[0002] Multiple cylinders will be installed in the mold, and the extending rod of the cylinder needs to be connected to the slider or core pulling structure of the mold, and a connecting ring is needed between the extending rod of the cylinder and the slider or core pulling structure, which plays the role of axial connection. The existing connecting rings generally have two structures. The first structure is that the four corners of the two semi-rings are drilled with screws for upper and lower connection and fixation. In this structure, the four corners of the rings are relatively small during processing, and the holes are easy to penetrate. The thread depth is shallow. After tightening, the rings are subjected to repeated and long-term movement of the cylinder connecting rod and the slider connecting rod, which can easily cause the connecting screws of the rings to loosen; the second structure is that the rings are connected and fixed by using screws through an external sleeve. This structure requires an additional ring sleeve to be made separately. This structure has the effect of preventing the upper and lower rings from loosening, but it increases the production cost and installation process. It is also necessary to first pass the sleeve through the cylinder connecting rod, and then embed it into it with the sleeve after the upper and lower rings are installed with the cylinder core pulling rod and the connecting rod. The installation is more cumbersome. Utility Model Content
