Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

Embodiment one:

the utility model provides a side cut mould for pivot, as shown in fig. 1, includes base 1, hypoplastron 3, takes off flitch 6, upper plate 2 and die shank from bottom to top in proper order, wherein:

the base 1 is provided with a mounting groove for the lower plate 3 to be embedded and mounted, the middle part of the mounting groove is provided with a falling opening 8, the shape of the falling opening 8 is matched with that of a pivot, and the shape of the falling opening is larger than that of the pivot, so that a cut product can fall;

the lower plate 3 is detachably arranged on the base 1, a trimming groove 5 is formed in the lower plate in a penetrating mode, the shape of the trimming groove 5 is matched with that of the pivot, so that the flash of the pivot can be better cut off, a knife edge is formed in the upper edge of the trimming groove 5, and the flash of the pivot can be abutted against the knife edge to be cut after the upper die 4 of the pivot is extruded;
