Quality, the stability of performance, and reduce the mould structure using injection-type fluorine glue of cost.
The purpose of this utility model can be realized by following technical proposal：A kind of mould knot using injection-type fluorine glue
Structure, including note seben, cold burden cavity plate, median septum, mo(u)ld top half cavity plate and the mo(u)ld bottom half cavity plate set gradually from top to bottom, in addition to difference
Lower impressions sheetmetal chuck, upper impression sheetmetal chuck and the note seben gold being connected with mo(u)ld bottom half cavity plate, mo(u)ld top half cavity plate and note seben
Belong to chuck, and lower impressions sheetmetal chuck, upper impression sheetmetal chuck and note seben metal chuck are connected with injector respectively,
It is characterized in that：There is the cold burden groove of some concave structures, cold burden groove circular in cross-section, and cold burden in described cold burden cavity plate
Groove top slot footpath is more than base channel footpath, and cold burden cavity plate is provided with the cold burden hole through cold burden cavity plate bottom surface and cold burden groove bottom land,
Described cold burden groove on the cell wall of notch to bottom land by having together using cold burden hole as axial screw shape swing-around trajectory.
When note seben moves downward with equipment, the fluorubber in cold burden groove is straight by median septum by swing-around trajectory
Connect and be injected into product die cavity.Swing-around trajectory and the cold burden groove of concave structure, which coordinate, can realize sizing material in fluorubber flow process
Between extrusion, shearing, reduce the Mooney viscosity of fluorubber, and there is guide effect, to improve the processing characteristics of fluorubber, and
The first in first out of fluorubber can be realized, it is ensured that fluorubber temperature and the uniformity of precuring, finally ensure fluorubber system
The quality stability of product.
In a kind of above-mentioned mould structure using injection-type fluorine glue, described cold burden groove longitudinal section is in half elliptic,
And major axis is coaxially disposed with cold burden hole corresponding to cold burden groove longitudinal section.
Therefore the processing characteristics of fluorubber can further be improved.
In a kind of above-mentioned mould structure using injection-type fluorine glue, the swing-around trajectory spiral shell in described some cold burden grooves
It is identical to revolve direction.
In a kind of above-mentioned mould structure using injection-type fluorine glue, described swing-around trajectory cross section is in be less than semicircle
Arc.
Compared with prior art, the utility model has the following advantages that：
When note seben moves downward with equipment, the fluorubber in cold burden groove is straight by median septum by swing-around trajectory
Connect and be injected into product die cavity.Swing-around trajectory and the cold burden groove of concave structure, which coordinate, can realize sizing material in fluorubber flow process
Between extrusion, shearing, reduce the Mooney viscosity of fluorubber, and there is guide effect, to improve the processing characteristics of fluorubber, and
The first in first out of fluorubber can be realized, it is ensured that fluorubber temperature and the uniformity of precuring, finally ensure fluorubber system
The quality stability of product.
