The specific embodiment

Compacting tool set of the present utility model, its preferable specific embodiment comprises part of the upper die and part of the lower die as shown in Figure 1 and Figure 2, wherein:

The part of the upper die comprises cope match-plate pattern 10, and the below of cope match-plate pattern 10 is fixed with upper mounted plate 8, and upper mounted plate 8 is fixed with a plurality of last die heads 12 that are provided with the core hole;

The upper fixed of lower bolster 3 has bottom plate 6, and the upper fixed of bottom plate 6 has low mold frame 7, and low mold frame 7 is respectively equipped with lower mode cavity corresponding to the position of die head on each 12, and the middle part of lower mode cavity is provided with central shaft 16 corresponding to the position in the core hole of last die head 12;

The underside of lower bolster 3 is provided with push pedal 17 and push rod push pedal 18, and the position corresponding to lower mode cavity in the push rod push pedal 18 is provided with push rod 13, and push rod 13 passes lower bolster 3 and bottom plate 6 extend in the lower mode cavity.
