Description
【発明の詳細な説明】
本発明はプラスチックの成型品を用いた電子レンジのド
アパネルに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a microwave oven door panel using a plastic molded product.
最近、プラスチックの多用途目的の為、プラスチックに
は無い性質の物質をプラスチックに混入することにより
優れた性質のプラスチック成型品を得ようとする研究が
進められ、製品化されるに至つている。Recently, in order to make plastics more versatile, research has been conducted to create plastic molded products with superior properties by mixing substances with properties that are not present in plastics, and this has led to commercialization.
本発明は此の様な最近の業界の技術動向に漏れることな
く優れた電子レンジのドアパネルを提供するものであり
、以下、その一例を添附図面に従つて詳細に説明する。The present invention provides an excellent microwave oven door panel that is consistent with the recent technical trends in the industry, and one example thereof will be described in detail below with reference to the accompanying drawings.
第１図に於いて１は後述する方法により成型された電子
レンジのドアパネルのプラスチックの成型品にして、プ
ラスチック部材２の背面に鉄粉層３を形成している。In FIG. 1, reference numeral 1 denotes a plastic molded product of a microwave oven door panel molded by a method described later, and an iron powder layer 3 is formed on the back surface of a plastic member 2.
而して、此の様な電子レンジのドアパネルを製造する方
法であるが、これは次の様な方法にて行うことが出来る
。The method for manufacturing such a microwave oven door panel is as follows.
５ 即ち、第２図に示す様に金型４を非磁性体、例えば
Ｃｕ−Ｂｅ合金から成る金型４Ａと透磁性体である鋼材
より成る金型４Ｂとより形成し、且つ此の金型４Ｂには
金型４Ａ、４Ｂ間に形成される型４Ｃにプラスチックの
溶融したものを流し込む１０為の湯道４Ｄを設けると共
に磁界発生手段５を埋設している。5. That is, as shown in FIG. 2, the mold 4 is formed of a mold 4A made of a non-magnetic material, for example, a Cu-Be alloy, and a mold 4B made of a steel material, which is a magnetically permeable material. A runner 4D for pouring molten plastic into a mold 4C formed between the molds 4A and 4B is provided in the mold 4B, and a magnetic field generating means 5 is embedded therein.
そして、此の様に形成されている金型にコロイド状の鉄

后、プラスチックが充分固まると共に冷却さフ０ れた
後両金型を分離し成型品を取り出すことに依つて成型は
完了する。尚、第４図はプラスチックが溶融される前の
状態を示すもので、プラスチックの粒子ＩＰ群に鉄粉３
Ｆｅが上述の様にスパイラルフローが落ちな石 い程度
混入されている。Then, a molten plastic mixed with colloidal iron powder to an extent that the spiral flow (flow after injection of hot water) does not fall into the mold formed in this way is poured from runner 4D, and the mold is heated for 15 minutes. The magnetic field generating means 5 is activated just before the pouring is almost completed and the plastic completely hardens within the mold. This forms the colloidal iron powder layer 3 floating in the plastic melt. Then, after the plastic has sufficiently hardened and cooled down, both molds are separated and the molded product is taken out, thereby completing the molding. In addition, Figure 4 shows the state before the plastic is melted, and 3 iron powders are added to the plastic particle IP group.
As mentioned above, Fe is mixed in to an extent that prevents spiral flow from occurring.
本発明は上述の様に電子レンジのドアパネルの背面に鉄
粉層を形成するものであるから、プラスチック成型の特
徴を生かして自由なデザインの電子レンジのドアパネル
と共に着色も自由にするこ１０とが出来る。Since the present invention forms an iron powder layer on the back surface of the microwave oven door panel as described above, it is possible to make use of the characteristics of plastic molding to freely design the microwave oven door panel and also to freely color the microwave oven door panel. I can do it.
そして本発明のように電子レンジのドアパネルに適用す

ラスチックでは不可能であつたのを可能にすることが出
来る優れた発明である。When applied to the door panel of a microwave oven as in the present invention, the iron powder layer shields radio waves, making it possible to achieve what was impossible with mere plastic.
