1. A method for manufacturing a handheld priming pump, the steps comprising:
step S1: injecting a plastic resin into a mold by an injector, the mold is combined with a first half mold and a second half mold, and a chamber having a priming pump shape is formed in the mold; step S2:returning the injector to a standby position while the chamber is injected full of the plastic resin, and a residue of the plastic resin is cut away the injector by a blade disposed adjacent to the injector; step S3: shifting the mold under a nozzle spaced from the injector; step S4: moving the nozzle to a top of the chamber of the mold and blowing such that the plastic resin in the chamber is then formed a first priming pump semi-finished product; step S5: returning the nozzle to an original position, and shifting the mold to a rail after cooling the mold, the rail is spaced from the nozzle and disposed at the side opposite to the nozzle; step S6: opening the mold after the mold moving to the rail such that the first half mold and the second half mold are separated each other and then continue shifting to the rail till the first priming pump semi-finished product is disposed on the rail; step S7: combining with the first half mold and the second half mold and at the same time driving a first knife and second knife to cut an upper portion of the first priming pump semi-finished product to form a second priming pump semi-finished product; and step S8: dropping the second priming pump semi-finished product into a box to collect.
