関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a mask coating method for coating using a mask.
車面用の成形品には、装飾性を高めるために部分的に塗
装を行うものがあり、この場合マスク塗装が行われる。Some molded products for car surfaces are partially painted to enhance their decorativeness, and in this case mask painting is performed.

A partially enlarged view, FIG. 8 is a perspective view of a part of the molded product. Frame 1
A coating film 3 is formed on the outer surface of the inner peripheral side of a frame-shaped molded article 2 made of synthetic resin.

合したものが一般的である。In the conventional mask painting method, the unpainted part 4 of the molded article 2 is covered with a mask 5, and the paint 7 is sprayed from the outside surface of the mask 5 using a paint gun 6 to form the coating film 3. Molded product 2 is AB
The mask 5 is molded from S synthetic resin, etc., and is often subjected to surface treatment such as chrome plating or undercoating on the entire surface.The mask 5 consists of a main body 5a and a tip member 5b.The main body 5a is made of a metal plate, and the tip is The member 5b is made by nickel electroforming, copper electroforming, etc. using the unpainted part 4 of the molded product 2 as a model, and the two are generally joined by a joining means 5c such as solder or brazing.

題点がある。However, in such a conventional mask painting method, the molded product 2 is deformed during molding or pretreatment, resulting in variations in shape, and the mask 5 also partially wears or deforms due to long-term use. Therefore, as shown in FIG. 7, a gap 8 larger than a predetermined value may occur between the tip member 5b of the mask 5 and the molded product 2. If spray painting is performed in such a condition, the spray paint may blow in the direction of arrow a from the gap 8 which is larger than the predetermined value, and the parting line 9 may be partially disturbed as shown in Fig. 8. . There is a problem that it is impossible to predict in advance where such a gap 8 will occur due to variations in each molded product 2 or mask 5.

を目的としている。This invention is intended to solve the above problems, and even if there are variations in the molded product and the mask, it prevents paint from entering between the molded product and the mask, and provides an excellent coating film with a clear parting line. The purpose of this study is to propose a mask coating method that can form a mask.
〔問題点を解決するための手段〕

ことを特徴とするマスク塗装方法である。[Means for solving the problem] The present invention covers the unpainted part of the molded article with a mask, and pressurizes the space formed between the inner surface of the mask and the unpainted part of the molded article. This is a mask painting method characterized by spray painting from the outside surface of the mask.

合うため、塗料の侵入が防止される。In the mask coating method of the present invention, the unpainted part of the molded article is covered with a mask, the space formed between the inner surface of the mask and the unpainted part of the molded article is pressurized, and the outer surface of the mask is When spray painting from the side, the space is under pressure, so the spray paint does not penetrate into the inner surface of the mask, and a coating film with clear parting lines is formed. In this case, of course, there is no problem if there is no gap above the specified level between the end of the mask and the molded product, but even if there is a gap above the specified level in some areas, air may blow out from this gap. At the tip of the mask, the sprayed paint and the airflow cancel each other out, preventing the paint from entering.

The figure is a cross-sectional view corresponding to A-A in FIG. 5 showing the coating method of the embodiment, and FIG. 2 is a partially enlarged view, and the same parts as in FIGS. The explanation will be omitted. 11
is a pedestal on which the molded product 2 is placed, and is in substantially contact with the end of the mask 5 to substantially seal the space 12 formed within the mask 5. The mask 5 is provided with an air supply port 13, and an air supply pipe 15 is connected to a cylinder 16 via a valve 14.

切線９の乱れはなく、優れた外観の塗膜３が得られる。The coating method is to apply the coating to the non-coated part 4 of the molded product 2 placed on the pedestal 11.
is covered with a mask 5, the valve 14 is opened and compressed air is supplied from a cylinder 16 to pressurize the space 12, and the paint 7 is spray-painted from the outer surface of the mask 5. At this time, if there is a gap 8 between the tip member 5b of the mask 5 and the molded product 2, air will blow out from the space 12 through the gap 8 in the direction of the arrow.
At the tip of the mask 5, the air flow of the sprayed paint 7 cancels out, so the paint 7 does not enter the gap 8, the parting line 9 is not disturbed, and a coating film 3 with an excellent appearance is obtained.

。The pressurization of the space 12 may be such that when there is a gap 8 between the tip member 5b of the mask 5 and the molded product 2, air is weakly blown out in the gap 8, and the pressure of the compressed air is sufficient to pressurize the space 12. The flow rate can be adjusted as appropriate depending on the size of the molded product 2, the gap 17 between the pedestal 11 and the mask 5, etc. Instead of the air supply port 13, an air supply port 13a may be provided in the pedestal 11.

する。FIG. 3 is a perspective view of a part of the mask in another embodiment as seen from the back side. Near the tip of the tip member 5b, an air flow path 18 is provided along the tip, and a communication path 19 is provided in the vicinity of the tip of the tip member 5b. It communicates with the space section 12. In this embodiment, there is a gap 8 at the tip of the tip member 5b, which saves time and effort for the molded product 2.
Even if the contact path 19 and the air flow path 1
8, air is supplied to the tip to equalize the pressurization of the tip.

２の形状に応じて任意の構造のものが使用できる。また
与圧手段としてはボンベ１６に限らず、圧縮機、ブロア
等によってもよい。In the above description, the mask 5 can have any structure depending on the shape of the molded product 2, which is a non-coated product. Further, the pressurizing means is not limited to the cylinder 16, but may be a compressor, a blower, or the like.
