the second suction assembly comprises a hollow pipe and a suction disc; the hollow tubes are enclosed to form a third channel; one end of the third channel is connected with the sucking disc, and one end of the third channel is connected with a vacuum device so as to vacuumize the third channel and enable the sucking disc to be in adsorption connection with the injection molding product; the second clamping component comprises a finger cylinder and a clamping jaw which are connected and used for clamping the nozzle material.

10. The matched inserter of the injection molding machine according to claim 9, wherein the mechanical palm further comprises a third worktable; the third workbench comprises a third mounting plate, a second telescopic cylinder, a guide assembly and a second ejector rod;

the third mounting plate is arranged between the first mounting plate and the second mounting plate, and the first mounting plate, the third mounting plate and the second mounting plate are sequentially stacked and arranged at intervals; the cylinder body of the second telescopic cylinder is fixedly connected with the third mounting plate, and the piston rod of the second telescopic cylinder is fixedly connected with the first mounting plate; the second telescopic cylinder is used for performing stretching and contracting motions; the guide assembly comprises a guide rod and a guide bearing; the guide rod is arranged between the first mounting plate and the second mounting plate and used for keeping the distance between the first mounting plate and the second mounting plate constant; the guide bearing is arranged around the guide rod and used for guiding the guide rod to reciprocate along a direction vertical to the first mounting plate and the second mounting plate; one end of the second ejector rod is fixedly connected with the third mounting plate; the other end of the second ejector rod is movably connected with the first channel;

when the second telescopic cylinder extends, the second telescopic cylinder drives the third mounting plate to move towards the direction far away from the first mounting plate, so that the second ejector rod moves out of the first channel to enable the first channel to accommodate the insertion of the casing material; when the second telescopic cylinder does contraction movement, the second telescopic cylinder drives the third mounting plate to move towards the direction close to the first mounting plate, so that the second ejector rod does movement of extending into the first channel, and the second ejector rod is used for ejecting the sleeve insert from the first channel.
