Abstract
The related manufacture and preparation technology special to a plastic shell with anti-electromagnetic radiation function for household electrical appliance comprises: preparing a outside-convex mould with size same as the appliance shell, and weaving the selected metal wire as the appliance shell mould to obtain the mesh-shaped padding; before injection molding, suspending the padding evenly in the injection mould, then continuing the manufacture process. The manufactured plastic shell has well solidity and heat-conductivity, low cost, and better electric insulation and security.
Description
Technical field:
The present invention relates to a kind of processing and preparing process of household electrical appliance plastic casing, particularly a kind of have anti-electromagnetic field wave radiation function and the preparation technology who strengthens heat radiation and strengthen the household electrical appliance plastic casing of mechanical strength, i.e. the electric appliance casing preparation of anti-electromagnetic radiation arranged.
Technical background:
Along with the fast development of electronic technology and information technology, the household electrical appliance of various types of model are ubiquitous.Current, occasion electrical equipment commonly used has television set, mobile phone, refrigerator, stereo set, computer, air conditioner, dehumidifier or humidifier, electric heater or the like in general family.During these household electric appliance operations, all be shaped on the electric signal processing circuit of various electric elements and various frequencies in its machine casing body.According to the theory that electromagnetic field in the physics is learned, all occasions that circuit is arranged and have the signal of telecommunication certainly exist various electromagnetic fields and radiation thereof around it.In fact, just exist complicated electromagnetic field radiation at present in our the common home environment, and this radiation is more and more serious.According to biology and medicine principle, any electromagnetic field and radiation thereof all can be to human body generation effects, and this effect is harmful and unhelpful often sometimes, all there is the interference to other household electrical appliance and signal thereof in this radiation simultaneously, so overcome or prevent that the external radiation field of household electrical appliance from being to improve the major issue that household electrical appliance should solve.At present, in the serious electric equipment of some radiation, generally adopt metal shell just can effectively solve radiation problem.But for most household electrical appliance, adopt metal shell to have that weight is big, cost is high, and shortcomings such as easy deformation affected by environment or damage, particularly use completely also there is the conduction unsafe problems in metal shell concerning the household electrical appliance that use forceful electric power.
Summary of the invention:
The objective of the invention is to overcome the shortcoming that exists in the prior art, seek and a kind ofly can effectively prevent or resist the household electrical appliance radiation that generates an electromagnetic field, can increase the mechanical strength properties of electric appliance casing again, and keep the method for manufacturing technology of former manufacturing cost substantially, this method is intended to utilize the tinsel network structure to prevent or the shell body of the principle processing and manufacturing household electrical appliance of shield electromagnetic radiation, and especially adopting plastics is the household appliances shell body of base stock.
In order to realize the foregoing invention purpose, the present invention adopts tinsel or cord to be woven into network structure earlier and has the netted mold that mates with the household appliances shell body, again the netted mold of tinsel is placed injection mold equably, and then become corresponding plastics electrical appliance shell by conventional preparation technology's extrusion molding of plastic casing body or injection moulding.
Braided metal wire mesh shape mold of the present invention is with the punch forming of metal cords cloth, or is that raw material uses braiding machine to weave to form with tinsel.
The present invention selects the tinsel of unlike material and different-diameter for use for the household appliances shell body of different electromagnetic field source and different volumes, and its line directly is 0.01～0.5mm; The material of tinsel comprises copper, steel, aluminium and alloy thereof etc.; The mesh of the netted mold of tinsel that is woven or net button are shaped as square, rhombus or other figures, and its size dimension size considers to have relation with the physical property and the corresponding mechanical strength of the anti-electromagnetic field of quilt.
The technology that the present invention prepares the plastic casing body comprises conventional plastic shaping methods such as extrusion molding and injection, the opposite opened mould is adopted in placement for the netted mold of tinsel in the injection, to be suspended in by the netted mold symmetrical expression of the tinsel that the electric appliance casing shape and structure is woven into earlier and split in the mould, make netted mold not contact mold wall, carry out injection moulding then, every section wire of the netted mold of tinsel is not exposed; For the electrical equipment plastic casing body that adopts the extrusion molding preparation, should form the clad type structure by making the netted mold of tinsel in the extrusion process not change shape and placing with the extrusion plastic shell body time among the plastic casing body.
The plastic casing body that the present invention makes, not only has the anti-electromagnetic field radiation, prevent the function that electromagnetic wave is excessive, and has a good heat conduction and heat radiation effect, by the tinsel in the plastic casing body heat is transmitted to every bit in the housing rapidly, reduce thermal source case temperature on every side fast, prolong its useful life.
The present invention compares with existing employing all-metal electrical appliance shell shielding or to the method for anti-electromagnetic field radiation; its design principle is reliable; the plastic casing body robustness of making is good; price is low; the heat conductivility height; can prolong the useful life of plastics matter household appliances shell body, the household electrical appliance plastic casing body that particularly this method is made also has excellent electric insulating, plays the safeguard protection effect.
Embodiment:
Be further described below by embodiment.
Embodiment 1:
Selecting diameter for use is the copper tinsel of 0.1mm, be woven into staggered form with Mechanical Method and twist metallic copper silk thread network structure that button tangles and the copper tinsel netted mold corresponding with television set main casing shape, forming the mesh length of side is the independent whole netted mold of fusiformis of 5mm; The netted mold of the copper cash that weaves is suspended in the plastics housing of TV set injection mold, and technology is carried out injection molding process and is made this electrical appliance shell routinely.
Embodiment 2:
Selecting diameter for use is the wire of 0.2mm, the stainless steel metal wire mesh shape mold that it is 10mm that the employing mechanical system is woven into the square mesh length of side, the planform of this mold is corresponding with the housing of TV set body structure, its size equals the interior outside median of housing of TV set body, the netted mold of wire is placed television set plastic casing injection mold, and technology is carried out injection moulding and is made the electrical equipment plastic casing body that has to anti-electromagnetic field radiation effect routinely.
Embodiment 3:
Selecting diameter for use is the aluminum metal cord cloth of 0.2mm, at first through the mechanical stamping moulding, makes corresponding electric appliance plastic casing body with embodiment 2 steps then.
After tested, the housing of TV set body that adopts above-mentioned enforcement to make can prevent the electromagnetic field radiation more than 80%, has played the favorable protection effect.
