Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1-3, the utility model provides a kind of technical solution: a kind of excavator shovel head point essence casting is with preventing shrinkage
Mold, including upper mold 1 and lower die 2 offer upper mold channel 11, the inner sidewall of the upper mold channel 11 in the middle part of the upper mold 1
It is socketed with demoulding circle 12, the four corners of the upper surface of the upper mold 1 are fixedly connected with pin 13, the upper surface of the upper mold 1
Middle part offers waxing road 14；
The middle part of the lower die 2 offers lower mold slots 21, and the inner cavity of the lower mold slots 21 slidably connects top plate 22,
For the front side wall of the inner cavity of lower mold slots 21 through there is hydraulic oil to enter channel 23, the hydraulic oil enters channel 23 through lower die
Have the lower end for being located at top plate 22 at 21 inner cavity of slot, offers the road Xia La 24, the road Xia La in the middle part of the upper surface of the lower die 2
24 mutually fasten with waxing road 14, and the four corners of the upper surface of the lower die 2 offer link slot 25, the link slot 25 and pin
