As shown in fig. 1, the insert injection mold disclosed by the invention comprises a movable mold 1 and a fixed mold 2, wherein a cavity 21 is formed in the end surface of the fixed mold 2 close to the fixed mold 2, a core 11 is connected to the end surface of the movable mold 1 close to the fixed mold 2 by using a bolt, and the movable mold 1 and the fixed mold 2 are assembled to mold a workpiece. As shown in fig. 2, two limit grooves 12 are provided on the end surface of the core 11 close to the movable mold 1, a limit rod 3 for positioning the nut is inserted into each limit groove 12, the outer wall of each limit rod 3 is attached to the inner wall of each limit groove 12, one end of each limit rod 3 far away from the movable mold 1 is in threaded connection with the nut to be implanted, and the nut and the core 11 are abutted to the end surface close to the fixed mold 2. When arranging the nut in the mould this moment, through with nut threaded connection in gag lever post 3, later utilize gag lever post 3 to inject the position of nut, the position that the nut was installed in the mould is difficult for appearing the error this moment to the size of the part that makes processing is difficult for receiving the influence.

As shown in fig. 2, when the nut is connected to the limit rod 3, the relative position between the nut and the limit rod 3 cannot be determined, and at this time, when the limit rod 3 is inserted into the limit groove 12, the distance that the limit rod 3 extends out of the limit groove 12 is too long, thereby affecting the mold closing of the movable mold 1 and the fixed mold 2. Therefore, the side wall of the limit rod 3 is coaxially provided with the abdicating groove 31, the abdicating groove 31 penetrates through the end surface of the limit rod 3 far away from the movable die 1, the nut is in threaded connection with the abdicating groove 31, and the nut is abutted against the end surface of the abdicating groove 31 far away from the fixed die 2. The relative position between the nut and the limiting rod 3 is limited by the abdicating groove 31, so that the length of the limiting rod 3 extending out of the limiting groove 12 is limited when the limiting rod is installed in the die, and the die closing process of the movable die 1 and the fixed die 2 is not easily influenced.

As shown in fig. 2, when the stopper rod 3 is moved and inserted into the stopper groove 12, one end of the stopper rod 3 away from the movable die 1 needs to be pinched by hand, and at this time, the length of the stopper rod 3 extending out of the nut is small, and the nut is difficult to grip. Therefore, the coaxial integrated into one piece of terminal surface that the gag lever post 3 kept away from movable mould 1 has extension rod 32, and extension rod 32's diameter is less than the diameter of groove 31 of stepping down, and extension rod 32 can not produce the hindrance to the removal of nut when being connected the nut with groove 31 of stepping down this moment, and when installing gag lever post 3 in the mould, directly utilize extension rod 32 to remove simultaneously, make gag lever post 3's removal more convenient.

As shown in fig. 2, when the stop rod 3 is unscrewed from the nut implanted into the workpiece, the process of rotating the stop rod 3 is troublesome because the surface of the stop rod 3 is smooth.
