Description
Technical field
The present invention relates to technical field prepared by mould, and in particular to a kind of oblique top preparation method in special-shaped water route and real
Apply the oblique top of the preparation method.
Background technology
In injection moulding process, cooling procedure very important effect for Forming Quality is played, because it can directly affect
Production efficiency and internal performance and the apparent mass of injection-molded item to injection.Excellent cooling system can significantly reduce cooling
Time, shorten the injection cycle cycle, reduce product residual thermal stress and buckling deformation, and strengthen the mechanical property of product and interior
Portion, surface quality etc..If injection-molded item inhomogeneous cooling is even, thermal residual strain can be produced, so as to the shape to injection-molded item, chi
Very little and performance etc. is brought and is had a strong impact on.Research test shows that the thermal residual strain of moulding is than flowing residual stress at least
Order of magnitude greater, therefore in injection molding process, should mainly consider the influence factor of thermal residual strain.When viscoelasticity is polymerized
When thing melt is cool below glass transition temperature in the mould, uneven variable density and uneven temperature change are all
Thermal residual strain can be formed.In injection moulding process, thermal residual strain is easily produced in following 2 stages:One is that injection-molded item exists
Cooling stage in die cavity, two is the stage that injection-molded item is cooled to room temperature from calcining temperature.Therefore, to accomplish that high efficiency is given birth to
Produce, and the injection-molded item of excellent, it is necessary to temperature adjustment is carried out to mould.
In injection mold, the cooling effect of mould is related to the Functionality, quality and appealing design of the height and final injection-molded item of production efficiency
Bad, the therefore design of its cooling system is to need one of key issue of consideration in die design process.But, due at this stage
Making mold means are limited, and lack suitable cooling water channel design theory so that the design of cooling water channel and manufacture can only
It is confined under relatively simple version.Even so, mold designers are still devoted to improving the cold of cooling system all the time
But efficiency, it is proposed that the different water route form such as spiral, dividing plate point cold type and spiral plug, so that mould can be obtained in front and back
Even and effectively cool down.But, when the product high to those complex structures and prescription carries out Design of Dies, said method
Not fully effective.
Content of the invention
This invention is not enough for current art, there is provided a kind of oblique top preparation method in special-shaped water route, by many suboptimums
The water route design of change, manufactures the excellent special-shaped water route of temperature adjustment and oblique top by 3D printing technique, improves mould or oblique top
Cooling effectiveness, shortening molding cycle, improve mould production efficiency, reduce moulding thermal residual strain, improve injection quality.
