Injection mold

An injection mold adapted for molding a product including an insert element, the insert element including a plurality of terminals each having a contacting portion, the injection mold comprising a male mold and a female mold movably engaged with the male mold, the male mold including:

• a male platen having a top surface which includes a front top surface, a substantial middle portion of the front top surface defining a first male groove extending along a longitudinal direction perpendicular to a front-to-rear direction of the male platen, a rear of the first male groove extending rearward, and then toward two opposite directions to form a second male groove, a rear portion of a bottom side of the first male groove defining a cavity communicating with the second male groove, two front portions of two opposite side surfaces of the cavity being concaved oppositely to form two clipping grooves with top ends thereof communicating with the first male groove, the front top surface defining a male sprue extending along the longitudinal direction with one end thereof connected with the second male groove and the other end thereof penetrating through a side of the male platen, the side surface of the cavity further defining a first fixing groove adjacent to the male sprue;
• a fastening element having a fastening body mounted in the front of the cavity, with two opposite side edges of the fastening body being inserted in the clipping grooves respectively, and a top end of the fastening body projecting into the first male groove of the male platen, the top end of the fastening body protruding upward to form a plurality of fastening lumps abreast arranged at regular intervals along the longitudinal direction, a fastening groove being formed between two adjacent fastening lumps for fastening the contacting portion;
• a supporting element having a supporting body accommodated in the cavity and behind the fastening element, a side surface of the supporting body defining a second fixing groove cooperating with the first fixing groove to form a fixing groove together;
• and
• a locating mold core having a base body fixed in the fixing groove, with a top end of the base body projecting into the first male groove of the male platen, the top end of the base body defining a locating groove aligned with one fastening groove for fixing one contacting portion adjacent to the male sprue.
