The utility model relates to injection mold technical field discloses a motorcycle side plate production injection mold, including a motorcycle side plate production injection mold, including upper die and lower die, the upper die bottom fixedly connected with core, the core inside is provided with the ejection assembly, the ejection assembly includes a plurality of top plates, the top plate top all are fixedly connected with buffer disc spring, buffer disc spring top all are fixedly connected with the connecting plate, the connecting plate top all are provided with power component, power component output all are fixedly connected with the push rod, the push rod outer wall all are equipped with the extension spring. In the utility model, the connecting plate and buffer disc spring are moved with the push rod of hydraulic ware and top plate, and make the extension spring force stretch, and the top plate will be shaped side plate and lift to take and hold for the staff, reach the effect that the carbon fiber surface damage caused by top plate is avoided, solve the problem that traditional stripping ejector pin stress concentration leads to product damage, improve the product surface quality.

The application discloses a high-strength steel coil inner circle indentation control method. The high-strength steel slab to be processed is subjected to hot rolling treatment to obtain a hot-rolled strip; the hot-rolled strip is subjected to ultra-fast cooling treatment to obtain a first cooling strip; the first cooling strip is subjected to laminar flow cooling treatment to obtain a second cooling strip; in the laminar flow cooling treatment, the laminar flow cooling treatment comprises first cooling treatment applied to a preset length region of the head of the first cooling strip and second cooling treatment applied to other regions of the first cooling strip; according to the hydraulic pressure increment of the pinch roll and the real-time roll gap increment, the biting time of the pinch roll is determined, and then the biting operation of the winding drum on the second cooling strip and the step control operation of the winding roll are performed, the winding treatment of the second cooling strip is completed, and a high-strength steel coil is obtained. According to the application, the inner circle indentation in the winding treatment process can be effectively eliminated.
