9. A molding method based on a molding apparatus as claimed in claims 1-8, characterized by the steps of:
(1) Aligning the locating hole and the locating pin on the lower surface of the needle cylinder on the rotating disc, so that the needle cylinder is sleeved on the outer side of the locating component;
(2) The first cylinder drives the lifting seat to ascend, so that the connecting rod pushes the sliding support outwards, and the positioning roller on the sliding support abuts against the inner side wall of the needle cylinder to finish positioning the needle cylinder;
(3) The second cylinder drives the compacting plate to move downwards to drive the positioning lug and the cleaning mechanism to move downwards together, the positioning lug is embedded into the groove on the outer side wall of the needle cylinder to be matched with each other, and the cleaning mechanism stretches into the needle cylinder; the lower surface of the compacting plate compacts the upper surface of the needle cylinder;
(4) The processing mechanism at one side far away from the nozzle drives the electric drill to drill blank holes on the side wall of the needle cylinder; then the second cylinder drives the compacting plate and the positioning convex blocks to be far away from the needle cylinder;
(5) The rotary disc rotates in a stepping manner for a certain angle, then the compacting plate continuously compacts the needle cylinder in the repeated step 4, and the processing mechanism continuously drills holes on the side wall of the needle cylinder, so that the processing mechanism can uniformly drill blank holes on the side wall of the needle cylinder;
(6) When the blank hole rotates 180 degrees along with the rotary disk, the lifting plate descends to enable the nozzle to be aligned with the blank hole, the nozzle is aligned with the blank hole to spray cooling oil, and then a processing mechanism close to one side of the nozzle drills threads inside the blank hole;
(7) Repeating the steps, and drilling screw threads on each blank hole on the needle cylinder;
(8) Taking down the syringe cleaning scraps, and uniformly placing and collecting the syringe cleaning scraps.
