本発明は、プラスチック成形品の表面に金属蒸着又は着
色材塗布箔およびフィルムから、加熱、加圧により文字
や意匠上の模様などを転写するホットスタンピング装置
の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a hot stamping device that transfers characters and design patterns from metal vapor-deposited or colorant-coated foils and films onto the surface of plastic molded products by heating and applying pressure. It is.
第１図は従来に於けるホットスタンピング装置を示し、
０１が熱板、０２がこの熱板０１の内面に張設されたシ
リコンラバー、０３が箔、０４がプラスチック成形品で
あって、熱板Ｏ１は図に示すように一体品であった。こ
のため、図に示すような成形品、すなわち角度や曲面を
有するプラスチック成形品０４用のシリコンラバーの場
合、予め熱による膨張を計算して製作（成形）しておく
にも拘らず、実際上はプラスチック成形品０４に対して
角度間隔りとＬ′が狂ったり、曲面ａの曲率が違ってき
たりする欠点があった。このため、ホットスタンピング
作業に支障をきたし、製品不良の最大の要因となってい
る。Figure 1 shows a conventional hot stamping device.
01 is a hot plate, 02 is a silicone rubber stretched on the inner surface of this hot plate 01, 03 is a foil, and 04 is a plastic molded product, and the hot plate O1 was an integrated product as shown in the figure. For this reason, in the case of a molded product as shown in the figure, that is, silicone rubber for plastic molded product 04 with angles and curved surfaces, even though the expansion due to heat is calculated in advance and manufactured (molded), the actual had the disadvantage that the angular spacing and L' were out of order and the curvature of the curved surface a was different from that of the plastic molded product 04. This hinders hot stamping work and is the biggest cause of product defects.
又、シリコンラバー製作の過程で、最終寸法を見い出す
までには何種類かの寸法のものを試作するため、この試
作費にも多くの費用を要する問題があった。In addition, in the process of manufacturing silicone rubber, prototypes of several different dimensions are made before the final dimensions are determined, which poses the problem of requiring a large amount of trial production costs.
本発明は斯かる点に鑑みて提案されるもので、熱板を分
割し、この分割部分に於ける間隙を調整することにより
、万一シリコンラバーの寸法が狂っている場合でも容易
にプラスチック成形品側に合致させることができるよう
にしたものである。The present invention has been proposed in view of this point, and by dividing the hot plate and adjusting the gap between the divided parts, even if the dimensions of silicone rubber are out of order, plastic molding can be easily performed. This allows it to match the quality of the product.
以下本発明の実施例を第２図に基づいて詳記すると、１
は熱板にして、この熱板ｌはその中央に於いて二分割さ
れており、分割部分には間隙１ａが形成されている。２
は前記熱板ｌの内面に張設れたシリコンラバー、３は金
属蒸着箔、４はプラスチック成形品である。Embodiments of the present invention will be described in detail below based on FIG. 2.
is a hot plate, and this hot plate l is divided into two parts at the center, and a gap 1a is formed between the divided parts. 2
3 is a silicon rubber stretched on the inner surface of the hot plate 1, 3 is a metal-deposited foil, and 4 is a plastic molded product.
なお、前記熱板１の間隙１ａは、熱板ｌの取付 ４・ボ
ルト（図示せず）の調節により、狭めたり広げたりする
ことができる。Note that the gap 1a between the hot plates 1 can be narrowed or widened by adjusting the mounting bolts 4 (not shown) of the hot plates 1.
本発明は以上のように、熱板１を中央に於いて二分割し
、この間隙１ａを微調整自在に構成したので、シリコン
ラバー２の寸法とプラスチック成形品４との間に寸法上
の誤差がある場合、間隙１ａの調整によりこの誤差を解
消することができる。As described above, in the present invention, the hot plate 1 is divided into two parts at the center, and the gap 1a is configured to be finely adjustable. If there is, this error can be eliminated by adjusting the gap 1a.
よって、シリコンラバー２の製作に際しては、成形型の
曲率と角度のみに留意し、寸法については概算でよく、
従来のようにシリコンラバー２を何枚も試作したりする
必要がない。又、使用によりシリコンラ；＜−２の寸法
に変化が生じた場合、従来であるとそれで終りであった
が、本発明によれば熱板１の間隙１ａの微調整により、
シリコンラバー２の寸法を調整し、更に使用することが
できる。実験によると、一枚のシリコンラバーで行える
ホットスタンピング回数は従来の場合１５，０００〜２
０．０００回であったが、本発明装置にしたことで４０
．０００〜５０．０００回可能となった。Therefore, when manufacturing the silicone rubber 2, pay attention only to the curvature and angle of the mold, and the dimensions can be approximated.
There is no need to make many prototypes of silicone rubber 2 as in the past. In addition, if a change in the dimensions of silicon la;
The dimensions of the silicone rubber 2 can be adjusted and further used. According to experiments, the number of hot stampings that can be done with one piece of silicone rubber is 15,000 to 2 with conventional methods.
0.000 times, but by using the device of the present invention, it was reduced to 40 times.
．． 000 to 50,000 times is now possible.
