Specific implementation mode
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
The every other embodiment obtained, shall fall within the protection scope of the present invention.
It please refers to Fig.1, Fig. 2, Fig. 3, the utility model provides a kind of technical solution：
A kind of novel hydraulic injection mold includes the upper die holder 1 and lower die holder 2 of corresponding setting, the setting of 1 top of the upper die holder
There are workbench 3, the workbench 3 to be provided centrally with injection cavities 4, the injection cavities 4 penetrate through 3 center of workbench and extend to
3 bottom surface of workbench, 1 bottom of the upper die holder are symmetrically arranged with cavity plate 7 along injection cavities 4；The lower die holder 2 is by ejection platform 9, base
