Parting line venting component, lower parting line venting component is identical with the gas deflation assembly structure on upper mould, makes air pressure in mould uniform by ventilating component,
Effectively reduce demoulding stress, it is ensured that stripping result is good.
The water inlet of first deflector is vertical with the axis of entrance guiding groove, the axis of delivery port and outlet guiding gutter
Vertically.
Rubber seal is provided between the entrance guiding groove of first deflector and upper mould cooling tube, ensures cooling circulation
In cooling water flow pressure, realize cooling water steady-state cycle flowing.
The lower mould is arranged in supporting table, and nitrogen spring is provided between supporting table and die shoe, utilizes its flex capability
Realize that pressure is constant and deferred action, working stability, compact structure.
The conformal cooling tube edges are identical with the distance between forming face, and the conformal cooling pipe is arranged substantially in parallel,
The diameter of conformal cooling pipe is identical with the distance between adjacent two conformal cooling tube edges, and cooling is uniform, and cooling effect is accurate.
The utility model compared with prior art, has the advantages that the utility model is simple in construction, effective drop
The maximum temperature of low flitch, the minimum problem on flitch is improved, enhance the uniformity of flitch temperature, enhance the whole of mould
Body reliability, the cooling system that deflector of the present utility model is formed with cooling tube, cooldown rate is high, and flow of cooling water is uniform,
