Embodiment
The utility model embodiment discloses a kind of PET bottle mold tool based on 3D printing, in die ontology
The retinue coolant flow channel consistent with die cavity profile is buried, solve that the cooling duct of prior art cathetus circular hole passage causes is cold
But the uniformity, cooling effectiveness are relatively low, cooling is unstable, can not meet the technical problem of actual demand, reduce the substandard products of PET bottle base
Rate improves production efficiency simultaneously.
Referring to Fig. 1, the utility model embodiment provides a kind of implementation of the PET bottle mold tool based on 3D printing
