Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, the present invention provides a kind of technical solution：A kind of excavator shovel head point essence casting mould for preventing shrinkage
Tool, including upper mold 1 and lower die 2,1 middle part of the upper mold offer upper mold channel 11, the madial wall socket of the upper mold channel 11
There is demoulding circle 12, the four corners of the upper surface of the upper mold 1 are fixedly connected with pin 13, the middle part of the upper surface of the upper mold 1
Offer 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, lower die
Has the front side wall of the inner cavity of slot 21 through there is hydraulic oil to enter channel 23, the hydraulic oil enters logical 23 and runs through lower mold slots 21
Be located at the lower end of top plate 22 at inner cavity, offer the roads Xia La 24 in the middle part of the upper surface of the lower die 1, the roads Xia La 24 with it is upper
Wax road 14 mutually fastens, and the four corners of the upper surface of the lower die 2 offer link slot 25, the link slot 25 and 13 phase of pin
Cooperation.
The present invention enters the use in channel 23 by top plate 22 and hydraulic oil, and lower mold slots 21 and upper mold are passed through in outer wax
Hydraulic oil enters channel 23 and is connected with external hydraulic pump when in tool slot 11, and the bottom surface that hydraulic oil enters top plate 22 is made to prevent cere
Shrinkage deformation, while by demould circle 12 use, realize the function of facilitating draft.
Specifically, the lower end of the top plate 22 is fixedly connected with supporting rod 3, the lateral wall of the supporting rod 3 is socketed with
Position-limiting tube 4, the position-limiting tube 4 are fixedly connected with the bottom surface of lower mold slots 22, make top when preventing hydraulic oil from entering extruding top plate 22
