Injection molding system

The utility model discloses an injection molding system. The injection molding system comprises a linkage part, a needle clamping mechanism and a side core-pulling mechanism, wherein the needle clamping mechanism is mounted on the linkage part and is provided with a clamping cavity for clamping an insert; the side core-pulling mechanism is driven by the linkage part to be slidably arranged betweena mold closing position and a mold opening position relative to the mold frame and is used for mounting the mold core; the driving mechanism drives the linkage part to slide relative to the die frame; wherein the first state and the needle clamping mechanism are relatively fixed and slide synchronously in the mold closing process that the side core-pulling mechanism slides from the mold opening position to the mold closing position, and the second state and the needle clamping mechanism are separated in the mold opening position in the mold opening process that the side core-pulling mechanismslides from the mold clos
