Embodiment Construction
[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0013] Such as Figure 1-2 As shown, an injection molding mold for agricultural machinery castings includes an upper mold 1 and a lower mold 2 . Protrusions 9 and fixing holes 8 are respectively provided on the surfaces of the upper mold 1 and the lower mold 2 , and the protrusions 9 and the fixing holes 8 are connected and fixed in cooperation with each other. The cavity 3 of the injection molding mold includes a first cavity 31 and a second cavity 32, and a stop post 4 is arranged between the first cavity 31 and the second cavity 32, and the stop post 4 is a rod with a groove 41 cylinders. In the first cavity 31 and the second cavity 32, a transverse block 10 is respectively provided along the direction of the transverse centerline of the first cavity 31 and the second cavity 32; Have " concave " type groove 7. The depth of the “concave” groove 7 is sma...
