The invention discloses a metal stamping part and injection part combination forming structure in a voice coil motor. The metal stamping part and injection part combination forming structure comprises a lower cover and two terminals, wherein the lower cover is rectangular; a through slot and an insertion hole are respectively formed in two adjacent corner parts; positioning columns are arranged at the periphery of the through slot; the terminals consist of connection parts and insertion parts; the connection parts are perpendicularly connected with the insertion parts; positioning holes are formed in the connection parts; the insertion parts on the two terminals are respectively arranged in the two insertion holes in a penetrating manner; the positioning holes in the connection parts of the terminals sleeve the positioning columns on the lower cover, and the connection parts cover a notch of the through slot of the lower cover. During assembling, the positioning holes in the connection parts of the terminals sleeve the positioning columns on the lower cover, and the connection parts cover the notch of the through slot of the lower cover; two corner parts of a lower elastic sheet are respectively welded on the top surfaces of the connection parts of the terminals mounted on the corner parts of the lower cover; the connection parts of the terminals cover the notch of the through slot of the lower cover, so that heat generated by welding of the lower elastic sheet and the terminals can be dissipated through the through slot of the lower cover, so that the lower cover is unlikely to deform.
