Detailed Description

As shown in fig. 2-6, the utility model relates to an supplementary drawing of patterns injection mold of ejector pin to one side, including ejector pin 1 to one side, ejector pin 2 to one side, ejector spring 3 to one side, locating pin 4, roof 5, cover half bottom plate 6, fixed die plate 7, movable mould board 8, square iron 9, movable mould bottom plate 10.

The fixed die bottom plate 6 is fixed with the fixed die plate 7, the fixed die plate 7 is abutted with the movable die plate 8, the movable die plate 8 is fixed with the movable die bottom plate 10 through square iron 9, the top plate 5 is arranged between the movable die plate 8 and the movable die bottom plate 10, the upper part of the inclined top 1 movably penetrates through an inner groove 81 of the movable die plate 8 and extends into the die cavity, the lower end of the inclined top 1 is slidably connected onto the top plate 5 in a groove block matching mode, the outer side of the upper part of the inclined top 1 is abutted with the wall of the inner groove 81 of the movable die plate 8, and the inner side of the upper part of the inclined top 1 extends into the die cavity and can be abutted with a buckle 101 of a formed product 100.

The top of the pitched roof 1 is provided with a step groove (or a step hole) 11, the inner end of the pitched roof thimble 2 is movably sleeved in a small groove (or a small hole) 111 of the pitched roof 1 step groove 11, the inner end of the pitched roof thimble 2 is provided with a limit groove 21, the limit groove 21 is movably sleeved on the locating pin 4, the locating pin 4 traverses the small groove (or the small hole) 111 of the pitched roof 1 step groove 11, the outer end of the pitched roof thimble 2 is movably sleeved in a large groove (or a large hole 112) of the pitched roof 1 step groove 11, the pitched roof spring 3 is sleeved in the large groove (or the large hole) 112 of the pitched roof 1 step groove 11, and two ends of the pitched roof spring 3 are respectively abutted on a hanging platform 22 of the pitched roof thimble 2 and a step surface of the pitched roof 1 step groove 11.

The utility model discloses a theory of operation:

1. as shown in fig. 2-4, at the beginning of mold opening, the outer side of the upper part of the inclined ejector pin 2 abuts against the wall of the inner groove 81 of the movable mold plate 8, and the inner side of the upper part of the inclined ejector pin 2 extends into the cavity to abut against the buckle 101 of the molded product 100.
