Description
Technical field
The invention belongs to mould applications, become shape heating cooling mould and its processing and application method the present invention relates to one kind.
Background technology
Mould is a kind of very important technological equipment in industrial production, and particularly application die-casting forming die, plastics are noted
Penetrate the type cavity moulds such as mould and produce various large-scale products, such as：Lampshade, notebook computer shell etc.；Various thin wall products,
Such as：Wave filter（Fin thickness is 0.2mm）Etc. being also required to be produced in enormous quantities using mould.Because the structure of product is answered
It is miscellaneous, it is selection well using mould molding, but the flowing due to material and Solidification Characteristics, the size shape of product are limited
System.
When material use mould molding is product, the influence of solidification is cooled, so that being completely filled with mold cavity
Before, solidify, it is impossible to obtain effective geomery.Particularly large product and thin wall product, due to large product chi
Very little big, the flowing stroke of material is long, to have time enough to flow before its solidification；For thin wall product, material is being full of
During die cavity, heat itself is few, there is the heat-absorbing action of the lower mold cavity of temperature again, causes material cooling quickly to coagulate
Gu, it is impossible to well full of die cavity.Summary reason, the shaping of large product and thin wall product is because by material flowability
Restriction and cannot further develop, restrict material flowability a major reason be exactly material rapid heat dissipation, premature solidification.
Material full of die cavity obtain shape after, it is necessary to even solidification, is just unlikely to form temperature stress and cause deformation of products.
To solve the formation problems of large product and thin wall product, have using following methods：
Have using through type water channel method, this method manufacture is relatively simple, and depth drill is used on the die cavity or core of mould
Processing.2. have using special-shaped water channel, i.e., constituted in the form of multiple straight courses intersection, the method is using depth drill along multiple side
To drilling, this some holes crosses insertion in some ad-hoc locations.3. semi-solid forming, i.e. aluminium alloy compression casting are used by low-melting alloy
It is heated to semisolid to be molded, while addition is easy to the material of material flowing in alloy molten solution.
Although however, more simple using the processing that through type water channel method and straight line intersect the special-shaped water channel water channel for constituting
It is single, but cooling-heating of this two classes water channel to core or die cavity work parts is not uniform enough, because water channel and work parts
The distance on surface has differences, it is impossible to form consistent temperature field in work component surface.Therefore, through type water method restriction
The size range of large product and thin wall product, stress deformation is will also result in during later product is cooled down.
There is proposition using special-shaped curve water channel, but under the pressure of curve channel structure complexity, and use 3D printing technique or entirety
Welding mode is obtained；It is limited by the limitation of 3D printing metal material technology, and overall welding technology is immature, will also result in mould
Have a large amount of wastes of material.So not seeing that the curve water channel of the method manufacture is employed also at present.
Using semi-solid forming, low-melting alloy is heated to semisolid, and addition is easy to material stream in alloy molten solution
Dynamic material.This method is very complicated in the equipment for making semi solid slurry；And semi-solid forming is only applicable to few
Low melting point alloy is molded, and is strictly limited in the species selection of product material.It may be said that the research of semi-solid forming is
It is that metallurgical category is covered.
The content of the invention
