The content of the invention
The purpose of this utility model is the deficiency for above-mentioned heat-insulating hot channel injection mold, is provided a kind of simple in structure, reliable
Property high, the low hot-runner injection mould condensate automatic cleaning machine structure of die manufacturing cost.
The technical solution of the utility model is as follows：
A kind of hot-runner injection mould condensate automatic cleaning machine structure, including well formula nozzle, sprue cup, locating ring and cover half
Plate；The well formula nozzle is stretched into sprue cup, is adjacent to the rim of a cup of sprue cup；The sprue cup is consolidated by locating ring
It is scheduled in solid plate；The locating ring is fixed on solid plate；Sprue cup and locating ring are fixed in the solid plate installation,
And the outer surface for being molded plastic；Air between the solid plate and sprue cup outer surface groove forms air-gap, uses
To form heat insulation layer.
Above-mentioned well formula spray nozzle front end is designed to dolioform.
Above-mentioned sprue cup outer surface opens up annular groove.
As the further scheme of the utility model：The length put in during the well formula nozzle operation in sprue cup depends on
In the radius of rim of a cup.
Preferably, the hot-runner injection mould condensate automatic cleaning machine structure is suitable for single-cavity heat-insulating hot channel injection mold.
The utility model has following beneficial effect：The utility model is that one kind is simple in structure, reliability is high, is manufactured into
This low hot-runner injection mould condensate automatic cleaning machine structure.The section of the sprue cup of heat-insulating hot channel injection mold in the utility model
It is coarseer, in injection moulding using the characteristic of plastics poor thermal conductivity, make the molten plastic condensation close to sprue cup inner wall
It is fully cured into one or the heat insulation layer condensate of semi-solid preparation, so as to play adiabatic effect；Well formula nozzle is stretched into sprue
In cup, by the heat that injector conducts the heating of well formula nozzle, the melt in sprue cup can be made to keep molten
State；Annular groove is opened up in the lateral wall of sprue cup, metal material is compared in the gap formed using solid plate and the groove, formation
The air-gap of poor thermal conductivity, so as to reduce the thermal loss in sprue cup.And the plastics in sprue cup centre are even
Molten condition is remained during continuous injection, the plastics of melting pass through the central passage of runner under the action of injection pressure,
Hence into mold filling is completed after cavity, plastic is finally formed after the cooling period.After production is injected, retreated by injection seat
Active force stretches into the dolioform structure of sprue cup front end using well formula nozzle, can be by the cured layer condensate in sprue cup
It is automatic to pull out outside mould, without manual cleaning.The utility model solves the problems, such as that the cleaning of heat-insulating hot channel injection molding condensate is difficult, carries
High the degree of automation of injection production and and production efficiency, reduce the cost of hot runner mould shaping plastic.
