Concrete, the two ends of described slide block are fastened with respectively piston rod contiguous block and side core contiguous block by screw, the upper end of described piston rod contiguous block offers draw-in groove, the end of described piston rod is fastened in described draw-in groove and is fastening by the threaded connector being arranged on described piston rod, and one end of described side core is extended and is fixedly connected with described side core contiguous block as connecting rod.
As preferably, described linear guides comprises a linear protrusion and two-lines guide pad, described two-lines guide pad is parallel with described linear protrusion and be arranged on the both sides of described linear protrusion, the bottom of described piston rod contiguous block, side core contiguous block and slide block all has a groove matching with described linear protrusion, and described piston rod contiguous block, side core contiguous block and slide block are consistent and consistent with the distance between described two-lines guide pad perpendicular to described width of loosing core in direction.
Concrete, also comprising the cylinder barrel contiguous block being fixedly connected with described cylinder barrel, described cylinder barrel contiguous block is fixedly installed on described support.
In addition, also comprise wedge block, can be by described wedge block restriction relative sliding between described slide block and described linear guides.
The beneficial effects of the utility model are, this oblique double hydraulic cylinder side core-drawing mechanism adopts hybrid syndeton, connection precision and kinematic accuracy between piston rod and side core have effectively been improved, adopt two locating pieces, reasonably determine the installation site of two side cores, improved installation accuracy and production efficiency.
