Description
本發明係有關於一種手機殼體製法及其結構，特別是指一種側壁成形為凹形之手機殼體製法及其結構。The invention relates to a method for manufacturing a mobile phone case and a structure thereof, in particular to a method for manufacturing a mobile phone case in which a side wall is formed into a concave shape and a structure thereof.
按，一般手機係如第1圖所示，具有對應之前、後殼體，且如圖中後側殼體所示，習知手機殼體10主要成形為具有凹形開口11形態之結構，該手機殼體10具有相對該開口11之一底壁12以及連接該開口11及該底壁12之一側壁13；值得注意的是，如第2圖所示，習知手機殼體10製程普遍需配合一成型模具A完成成型步驟，其中，如第二圖所示，定義該凹形手機殼體10的開口11相對兩側具有一寬幅W，且該側壁13相對兩側內面131之間具有一距離D，藉此，習知手機殼體10成品為了方便從成型模具A脫模，其側壁13必須成形為直立殼壁形態，使手機殼體10的開口11寬幅W具有與側壁13距離D相當之長度。According to the first mobile phone system, as shown in FIG. 1 , there are corresponding front and rear casings, and as shown in the rear casing of the figure, the conventional mobile phone casing 10 is mainly formed into a structure having a concave opening 11 shape. The mobile phone case 10 has a bottom wall 12 opposite to the opening 11 and a side wall 13 connecting the opening 11 and the bottom wall 12; it is noted that, as shown in FIG. 2, the conventional mobile phone case 10 The process generally requires a molding die A to complete the molding step. wherein, as shown in the second figure, the opening 11 of the concave mobile phone case 10 is defined to have a width W on opposite sides thereof, and the side walls 13 are opposite to each other. There is a distance D between the faces 131. Thus, in order to facilitate the release of the finished product of the mobile phone case 10 from the molding die A, the side wall 13 must be formed into an upright shell wall shape so that the opening 11 of the mobile phone case 10 is wide. The web W has a length corresponding to the distance D of the side wall 13.
惟目前3C產品相當多樣化，如何以具有設計感之外觀吸引消費者已成為影響銷售量的關鍵之一，雖有手機產品設計師將設計變化延伸至手機殼體10的側壁13與底壁12結合線形態上，然而在考量降低製造成本後，如第3圖具有開口23寬幅W小於側壁22最大距離Dmax 之手機殼體20形態，因有脫模困難之問題，導致習知手機殼體10側壁13仍 未脫前述直立殼壁形態，形成手機殼體10外觀設計之限制，故習知手機殼體製法實有待改善之空間。However, the current 3C products are quite diverse. How to attract consumers with a design-like appearance has become one of the keys to affect sales. Although mobile phone product designers extend design changes to the side walls 13 and the bottom wall of the mobile phone case 10. 12, in combination with the line form, however, after considering the reduction of the manufacturing cost, as shown in FIG. 3, the shape of the mobile phone case 20 having the opening width W of the opening 23 being smaller than the maximum distance D max of the side wall 22 is caused by the problem of difficulty in demolding, resulting in the conventional knowledge. The side wall 13 of the mobile phone casing 10 still does not take off the form of the upright casing wall, which forms a limitation of the design of the mobile phone casing 10. Therefore, there is a space for improvement in the conventional mobile phone casing manufacturing method.
