Description
본 발명은 자동차용 선 바이저 제조시 외피(P.V.C SKIN)의 테두리부를 용접(접합)하는 고주파 금형을 개량한 것으로서, 고주파 금형의 상.하 용접단자 중에서 상부금형의 단자를 하부금형의 단자보다 1㎜이내에서 작게 형성하여 용접시 백 비이드(BACK BEAD)가 어긋난 단차부에 형성되어 용접강도 향상 및 터짐발생을 억제토록 한 것이다.The present invention is an improvement of a high frequency mold for welding (bonding) the edges of the PVC skin to the manufacture of a sun visor for automobiles. The upper and lower welding terminals of the upper and lower welding terminals of the high frequency mold have a thickness of 1 mm. It is formed to be small within the back bead (back bead) during the welding is formed in the stepped portion is shifted to improve the welding strength and suppress the occurrence of burst.
잘 알려진 바와 같이 자동차용 선 바이저는 P.V.C 재질로 된 두겹의 외피 사이에 내장재를 넣고 테두리부를 고주파 용접하여 제작되는데, 이러한 종래 고주파 금형의 용접단자를 제5도를 통해 살펴보면, 상부금형과 하부금형의 용접단자가 뾰족하게 형성되면서 수직선상에서 일치되도록 구성되어 있어서, 용접을 하고 나면 제2도에 도시된 바와같이 두겹의 외피 중앙부에만 비이드가 형성된다.As is well known, automotive sun visor is manufactured by inserting the interior material between two layers of PVC material and welding the rim at high frequency. Looking at the welding terminal of the conventional high frequency mold through FIG. 5, the upper mold and the lower mold The weld terminals are sharply formed and matched on a vertical line, and after welding, beads are formed only at the center of the double-layered shell as shown in FIG.
그러나, 상기와 같이 두겹의 외피 중앙부에만 비이드가 형성되므로, 용접부의 강도가 약하여 쉽게 터져버리는 경우가 허다하고, 내장재와 외피가 타이트하게 용접되지 못하는 등 용접작업시의 불량률 또한 매우 높게 나타나는 문제점이 있었다.However, since the bead is formed only at the center of the two-ply outer skin as described above, the weld part is weak and often breaks easily. there was.
본 발명은 전술한 문제점을 개량하고자 안출된 것으로, 고주파 금형의 용접단자를 개량하여 고주파 용접시 용접강도를 향상시키고, 터짐발생을 억제시킬 수 있도록 하는 것을 그 목적으로 하는 것이다.SUMMARY OF THE INVENTION The present invention has been made to improve the above-described problems, and an object thereof is to improve the welding terminal of a high frequency mold to improve the welding strength during high frequency welding and to suppress the occurrence of bursting.

상기와 같은 목적을 달성하기 위한 본 발명을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention for achieving the above object will be described in detail with reference to the accompanying drawings.
제3도는 본 발명에 따른 고주파 접합장치를 나타낸 정면도이고, 제4도는 본 발명에 의해 접합된 선 바이저의 요부확대 단면도이며, 제6도는 본 발명에 따른 고주파 금형의 용접단자를 나타낸 요부확대도로서, 도시된 바와 같이 본 발명은 차량용 선 바이저(1)를 제조시 테두리부를 용접하는 고주파 금형(2)의 상,하부 용접단자(3)(3')중 상부 용접단자(3)는 일측에만 경사진형으로 구성하고, 하부 용접단자는형으로 구성하되, 상부 용접단자(3)를 하부 용접단자(3')보다 1㎜범위내에서 안쪽으로 치우치게 형성하여 하부 용접단자(3') 내측면이 어긋나도록 구성된 것이다.Figure 3 is a front view showing a high frequency bonding apparatus according to the present invention, Figure 4 is an enlarged cross-sectional view of the main portion of the line visor bonded by the present invention, Figure 6 is an enlarged view showing the main portion of the welding terminal of the high frequency mold according to the present invention As shown, the present invention, the upper welding terminal (3) of the upper and lower welding terminals (3) (3 ') of the high-frequency mold (2) for welding the rim when manufacturing the vehicle sun visor (1) is limited to one side only. Picture The lower weld terminal The upper welding terminal 3 is formed to be biased inwardly within the range of 1 mm from the lower welding terminal 3 'so that the inner side of the lower welding terminal 3' is shifted.
도면중 미설명된 부호 10은 선 바이저의 내장재또한 단차11은 용접시 발생하는 비이드(BEAD)이며, 12는 선 바이저의 외피이다.In the drawing, reference numeral 10 denotes a built-in material of the sun visor, and step 11 is a bead generated during welding, and 12 is an outer shell of the sun visor.
이러한 구성의 본 발명은 용접부위가 고주파 금형(2)의 안쪽이 되므로 벌어질려는 힘을 받는 외피(12)의 절곡부위에 용접을 하게 되는 것이고, 용접작업시 상부 용접단자(3)가 하부 용접단자(3')보다 내측으로 치우쳐 있으므로, 선 바이저(1)의 외피(12) 또한 단차가 생기는 상태로 용접이 되는 것으로서, 용접 비이드(11)가 종래에 비하여 더욱 넓게 분포됨으로 인한 강도 향상효과를 누릴 수 있게 되는 것이다.The present invention of such a configuration is to be welded to the bent portion of the outer shell 12 which is subjected to the force to be opened because the welding portion is the inside of the high frequency mold (2), the upper welding terminal (3) during the welding operation is the lower welding Since the outer shell 12 of the sun visor 1 is also welded in a state where a step is generated because it is biased inward from the terminal 3 ', the strength improvement effect due to the wider distribution of the welding bead 11 than in the related art. Will be able to enjoy.
또한, 용접부위가 외피(12) 절곡부의 가장 안쪽이 되므로 외피(12)가 내장제를 완전히 조이면서 유동없이 용접되는 효과도 얻는다.In addition, since the welded portion becomes the innermost portion of the bent portion of the outer shell 12, the outer shell 12 is also completely tightened and the welding effect is obtained without flow.
이상 설명한 바와같이 본 발명은 고주파 금형(2)의 상,하부 용접단자(3)(3')를 간단하게 개량함으로써, 선 바이저(1)의 용접부에 강도가 일층 향상되어 용접부위가 터지는 경우를 예방할 수 있고, 생산시에 불량률을 낮출 수 있는 등 그 효과가 매우 뛰어난 발명이다.As described above, according to the present invention, the upper and lower welding terminals 3 and 3 'of the high frequency mold 2 are simply improved, whereby the strength of the weld portion of the sun visor 1 is further improved and the welding portion is blown. It is the invention which is very excellent in the effect which can be prevented and the failure rate can be reduced at the time of production.
