A drug carrying groove 103 is arranged on the slender drug carrying tube 102. Since the slender drug carrying tube 102 needs to be pushed into the human body and the drug carrying groove 103 corresponds to administer drugs to the corresponding area, the precision requirements for the slender drug carrying tube 102 and the drug carrying groove 103 are high.
[0003] At the current stage of the molding method, when the injection pressure is insufficient, the molding precision of the slender drug carrying tube 102 and the drug carrying groove 103 cannot be guaranteed.

A plurality of lower mold inserts matching the drug carrying grooves are arranged on the lower mold cavity. And the lower mold is provided with a molten raw material inlet. The molten raw material inlet is communicated with the lower mold cavity through a flow channel and an injection port. And a first auxiliary pressurization component is correspondingly arranged at the molten raw material inlet. A second auxiliary pressurization component used in cooperation with the first auxiliary pressurization component is correspondingly arranged at the flow channel.
[0009] Both the first auxiliary pressurization component and the second auxiliary pressurization component include a pressurization channel opened on the lower mold. A pressurization lifting column is arranged in the pressurization channel.
[0010] Further, a lower mold insert lifting sliding sleeve is correspondingly arranged at the lower mold cavity.
[0011] Further, the upper mold cavity has an upper mold cavity A and an upper mold cavity B for the tube handle part and the slender drug carrying tube. Correspondingly, the lower mold cavity has a lower mold cavity A and a lower mold cavity B matching the upper mold cavity A and the upper mold cavity B.
[0012] Further, the injection port is communicated with the lower mold cavity A.
[0013] Further, the injection port is in the shape of a tapered horn, and the smallest diameter part communicates with the bottom of the lower mold cavity A.
[0014] Further, a molten raw material inlet communicates with the symmetrical lower mold cavities A through the injection port.
[0015] Compared with the prior art, in the injection molding process of the present utility model, through the pressurization method of collaborative auxiliary pressurization, when injection molding, pressurization is carried out by raising the pressurization lifting column to ensure the injection molding pressure, and thus the molding accuracy is ensured.
