Summary of the invention
The object of the invention is to the deficiency for the preparation method of existing thermostat housing and defect, provide an a kind of mould of efficient thermostat housing to have more preparation method, to solve the problem.
Technical problem solved by the invention can realize by the following technical solutions:
One mould of efficient thermostat housing has more preparation method, adopts Shooting Technique preparation, comprises the following steps:
(1), there is cavity assembling thermostat casing body profile patrix and inside and has protruding thermostat casing body profile counterdie in cavity, and be provided with inner mould core in the projection of thermostat casing body profile counterdie, forms a mould and has more mould;
(2), a mould is had more mold heated to 80 ~ 120 DEG C;
(3), with PETG as raw material add in reactor be heated to 120 ~ 165 DEG C after vacuumize and dehydrate, the time of dehydrating is 3 ~ 5 hours, makes the humidity of PETG to be less than 0.02%;
(4), by the raw material processed through step (3) injection machine is added and injection moulding has more mould molding to a described mould, wherein, nozzle temperature: 250 ~ 295 DEG C, screw rod rotating speed: 50 ~ 100rpm, injection pressure: 300 ~ 1300bar;
(5), a described mould had more mold heated to 110 ~ 140 DEG C and keep 1 ~ 2 hour;
(6), take out the mould processed through step (5) and have more mould, thermostat casing body profile patrix is removed from thermostat casing body profile counterdie, in type injection molding PETG thermostat housing is taken out from the cavity of thermostat casing body profile counterdie, the inside of inner mould core from injection molding PETG thermostat housing is taken out, thermostat housing manufacture completes again.
In a preferred embodiment of the invention, in step (3), in reactor, crystallization reinforcing agent is added with.
Owing to have employed technical scheme as above, beneficial effect of the present invention is: the preparation method had more by an above-mentioned mould, not only increase preparation efficiency, and the thermostat housing prepared is functional, there is excellent high-and low-temperature resistance performance, can in 150 DEG C of temperature ranges Long-Time Service, can resistance to-70 DEG C of low temperature, and very little to its mechanical impact during high and low temperature, meet the working environment of engine cold heat exchange.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, setting forth the present invention further.
