Abstract
The present invention relates to a kind of refrigerator part, particularly disclose a kind of hinge special for refrigerator.This hinge special for refrigerator, is characterized in that: with aluminium, copper, magnesium and iron for raw material, mixes die casting form by certain weight proportion at 430 ~ 438 DEG C.Preparation technology of the present invention is simple, and cost of production is low, and environmental protection and energy saving are pollution-free, does not sturdy and durablely rupture, and can adapt to different temperatures demand and use, be suitable for wide popularization and application.
Description
(1) technical field
The present invention relates to a kind of refrigerator part, particularly a kind of hinge special for refrigerator.
(2) background technology
Existing refrigerator is all use hinge arrangement to be installed on refrigerator body by door body, thus a body can be rotated relative to refrigerator body.Refrigerator hinge has various shape structure, simultaneously in order to guaranteed strength, needs to adopt metal material manufacture.In view of the environment for use of refrigerator, require that the hinge be used in refrigerator doors not only needs to have good rustproof property, make hinge not corrosion in the clammy for a long time environment of refrigerator inside, require that hinge has good mechanical performance simultaneously, fracture and distortion can not be there is when making the heavier refrigerator doors of hinge bearing ratio repeat open and close, ensure that refrigerator doors can be rotated automatically around hinge axis.
In order to make refrigerator doors have above-mentioned characteristic, the material being used as refrigerator doors hinge is at present kirsite, but kirsite is as refrigerator doors hinge, and cost is higher, and intensity and decay resistance aspect neither be very high.
(3) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides a kind of environmental protection and energy saving, robust hinge special for refrigerator.
The present invention is achieved through the following technical solutions:
A kind of hinge special for refrigerator, it is characterized in that: with aluminium, copper, magnesium and iron for raw material, mix die casting and form at 430 ~ 438 DEG C, wherein, the weight fraction of each raw material is, aluminium 3.5 ~ 4.3%, copper 0.75 ~ 1.25%, magnesium 0.03 ~ 0.08%, and all the other are iron.
The present invention prepares material compared to former hinge, improves its material composition and formula, increases aluminium component, regulates simultaneously, change its performance to the interpolation proportioning of raw material, makes it more sturdy and durablely not rupture, and is convenient to adapt to different temperatures demand and uses.
The weight proportion of its preferred each raw material is, aluminium 3.9%, copper 1%, magnesium 0.05%, and all the other are iron.
Described raw material mixing die casting adopts the Hpdc machine of 80000KN, forms through high-accuracy die casting.
The material prescription of product of the present invention goes through repetition test many times, and experienced by the finished product user service test of 3 years multi-product products, the user through up to ten thousand refrigerator products uses follow-up investigation, and anti-reflecting bending strength test reaches 1600N, durable in use, good product performance.
Preparation technology of the present invention is simple, and cost of production is low, and environmental protection and energy saving are pollution-free, does not sturdy and durablely rupture, and can adapt to different temperatures demand and use, be suitable for wide popularization and application.
