The working process of the vertical movable die first-pulling sliding block inclined core-pulling die provided by the embodiment of the utility model is as follows: when the die is closed, the fixed die core and the movable die core form a die cavity in a surrounding mode, the sliding block inserts at the top ends of the first sliding block 12 and the second sliding block 16 are also positioned in the die cavity to form a part of the die cavity, the two sliding block inserts occupy positions in the die cavity, and the part corresponding to the sliding block inserts is a counter bore formed in the surface of a workpiece;

injecting a molten material into a cavity by a forming machine, cooling the material to form a workpiece, and then opening a die;

when the mold is opened, the stripper plate 2 and the fixed mold plate 3 are opened firstly, and a material handle in a runner is disconnected with a workpiece;

when the fixed template 3 moves to a set distance, the stripper plate 2 is pulled to be separated from the fixed mould picking and placing plate 1, so that a material handle is stripped from the sprue bush and the material pulling rod;

because the mould locking device 17 is arranged between the fixed mould plate 3 and the movable mould bottom plate 6, the fixed mould plate 3 and the movable mould plate 4 are relatively fixed in the mould opening process, the movable mould plate 7 and the movable mould bottom plate 6 are separated,
