The deep hole inner upper end of PIN needle body is set, and offers water inlet and water outlet on the mould housing side wall, water inlet by into
Aquaporin is connected with the arrival end of cooling duct, and water outlet is connected by exhalant canal with vertical through holes upper end.
Preferably, the cooling duct of the liquid drugs injection seat includes vertical counterbore and cross through hole, the liquid drugs injection on vertical counterbore top
The plug-in opening for water spray pin inserting is provided with seat, vertical counterbore base is connected with cross through hole, cross through hole end and water inlet
Passage connects.
Preferably, it is provided with the first seal washer between the PIN needle body bottom end face and mould housing top surface.
Preferably, it is provided with the second seal washer between the liquid drugs injection pressing plate upper surface and installation groove body.
Preferably, it is fixedly connected between the liquid drugs injection pressing plate and liquid drugs injection seat by screw.
Compared with prior art, the beneficial effects of the utility model are：Increase water route cooling cycle inside PIN needle body
Afterwards, the cooling time of BOSS columns shortens, and product smooth can depart from PIN needle body, and the service life of PIN needle body is greatly prolonged, overcome
The problem of upper product temperature Gao Ernan of shaping takes, and PIN needle body is easily broken, shortens molding cycle, saves cost.This reality
With new structure connection and reasonable arrangement, PIN needle body service life greatly prolongs, and BOSS columns smooth can depart from PIN needle body, shorten shaping week
Phase.
