[0027] Referring now to Figure 1 to image 3 , the partial plastic-coated product according to the first embodiment will be described. Partially plated plastic products are used as vehicle exterior parts such as grilles, fog lamp covers, and the like.

[0028] Figure 1A A cross-sectional structure of a part of a partially plated plastic article 10 is shown. Figure 1B yes Figure 1A A magnified view of a portion of . exist Figure 1A and Figure 1B Among them, the upper side corresponds to the front side of the partially plated plastic product 10 , or the design surface side, and the lower side corresponds to the rear side. The front-to-back direction coincides with the demolding direction of the half-molds 35, 36 used to mold the intermediate product 48 consisting of the first base member 11 and the second base member 21 discussed below.

[0087] Below, refer to Figure 4A and Figure 4B , the partial plastic-coated product according to the second embodiment will be described.

[0088] The second embodiment is similar to the first embodiment because the first corner portion 14 has an arcuate wall surface 15 and an upright wall surface 16 . Like the first embodiment, the upright wall surface 16 is constituted by a flat surface extending from the arc-shaped wall surface 15 in a direction intersecting the general wall surface 13 of the first base member 11 in a substantially perpendicular manner.

[0089] In the second embodiment, the inclined wall surface 26 at the second corner portion 22 is in contact with the arc-shaped wall surface 15 instead of the upright wall surface 16 . The area between the inclined wall surface 26 and the arc-shaped wall surface 15 constitutes the groove 24 .

[0090] In the second embodiment, the first corner portion 14 has a fan-shaped section with a central angle α of 85 degrees. ...

Abstract

A partially plated plastic product includes a first base member and a second base member that are made of different plastic materials. The first base member includes a first corner portion having a curved wall surface. The second base member includes a second corner portion. The first and second corner portions are located on a front side of the product. The first and second base members are adjacent to each other at least at the first corner portion and the second corner portion. Only one of the first and second base members includes a metal coating film formed on a region of an outer surface of the base member with which the other base member is not in contact. The second corner portion includes a groove forming portion. The groove forming portion forms a groove between itself and at least the curved wall surface of the first corner portion.

Description

technical field [0001] The invention relates to a partially coated plastic product comprising a first base part and a second base part made of different plastic materials. A metal coating film is formed on an outer surface area of ​​one of the base members that is not in contact with the other base member. Background technique [0002] The first base member and the second base member in this partially-plated plastic product are sequentially molded by two-color molding. Afterwards, for example, a metal coating film is formed on an area not in contact with the second base member in the outer surface of the first base member, thereby making a partially plated plastic product (for example, referring to Japanese Patent Laid-Open No. 2005-100964 and No. 2010- 33942). [0003] Figure 9 One form of such a partially coated plastic product is shown in . The partially plated plastic product 70 includes a first base member 71 and a second base member 73, at least at the first corner...
