[Industrial applications]

 The present invention relates to an automobile side protector mold in which a clip can be easily attached to a molding body having a hollow thick portion formed by a hollow injection molding method.

[0002]

[Prior art]

 The most common structure of a conventional side protector molding (hereinafter also simply referred to as “side molding”) having a structure in which a molding body is attached to a side surface of an automobile body using a clip is as shown in FIG. is there. That is, in the molding body 51 having a C-shaped cross section, the flange portions 52 are integrally formed in the inner portion of the opening so as to face each other, and the pair of flange portions 52 form a base end of a clip (not shown). The clip was attached to the molding body 51 by engaging the parts. In order to injection-mold such a mold main body 51, the use of the pair of slide dies 53 is indispensable because the inner parts of the pair of flanges 52 are undercut. For this reason, the structure of the molding die is complicated, and it is expensive, which in turn increases the manufacturing cost of the side molding itself.

On the other hand, when a resin molded product partially having a thick portion is injection-molded, gas is injected following the injection of the resin, and the pressure is maintained thereby, so that the hollow portion of the molded product is hollow. A hollow injection molding method (gas-assisted injection) is performed to form a portion and prevent sink marks and warpage from occurring in this portion. By this hollow injection molding method, it is also possible to mold the molding body of the side molding which is the subject of the present invention, and in this case, the thick portion has a hollow structure.

[0004]

[Problems to be solved by the device]

 The present invention utilizes the hollow thick portion formed when molding the molding body by the hollow injection molding method, and the clip can be engaged with this thick portion to simplify the shape of the molding body. Therefore, it is an object to simplify the structure of the molding die and reduce the overall thickness of the molding body.

[0005]

[Means for Solving the Problems]

 In order to solve this problem, the first means adopted by the present invention is a molding body having a substantially C-shaped cross section, and a molding body for horizontally mounting the molding body on the most protruding portion of the side surface of the automobile body. In a side protector molding for an automobile, which comprises a clip, a pair of hollow thick-walled portions are formed in the longitudinal direction inside both ends in the width direction of the molding body by a hollow injection molding method, and the pair of hollow thick-walled portions is formed. The pair of clip engaging portions are formed by cutting out the portions opposite to each other, and the mounting plate portion provided at the proximal end portion of the clip is engaged with the pair of clip engaging portions, thereby This means that the clip mounting plate is arranged along the width direction of the molding body, and the clip is attached to the molding body. The second means is to form a hollow thick portion in the longitudinal direction inside the widthwise central portion of the molding body by a hollow injection molding method, and cut the hollow thick portion by a predetermined length. Clip mounting portions are formed on both ends of the clip engaging portion, and the mounting plate portions provided on the proximal end portions of the clips are engaged with the clip engaging portions, so that the mounting plate portions of the clip are molded. The clip is attached to the molding body along the longitudinal direction of.

[Effect of device]

 As described above in detail with reference to various embodiments, according to the present invention, the hollow thick-walled portion is formed along the longitudinal direction at both end portions in the width direction of the molding body or the central portion thereof by the hollow injection molding method. The clip engaging portion is formed by notching the hollow thick portion corresponding to the shape of the molding main body engaging portion provided at both ends of the clip mounting plate portion, and the clip engaging portion is utilized. Since the clip is attached to the mall body, the shape of the mall body can be simplified in a mall in which the clip is used to horizontally attach the mall body to the side surface of the automobile body. As a result, the structure of the mold for molding the molding body becomes simpler, which in turn reduces the manufacturing cost of the molding body itself. Also, since the clip engaging portion provided in the hollow thick portion of the molding body is used to attach the clip to the molding body, the overall thickness of the molding body can be reduced.
