Description
技术领域technical field
本实用新型涉及将车身开闭部的间隙密封的密封条(weather strip)。The utility model relates to a weather strip for sealing the gap of an opening and closing part of a vehicle body.
背景技术Background technique
作为汽车用密封条,以往已知日本特开2009-179068号公报(专利文献1)记载的密封条。专利文献1记载的密封条包括模具成形部和挤压成形部,二者的端部彼此接合。As a weather strip for automobiles, a weather strip described in JP-A-2009-179068 (Patent Document 1) has conventionally been known. The weather strip described in Patent Document 1 includes a molded portion and an extruded portion, both ends of which are joined to each other.
上述传统的密封条存在下述问题。即,当挤压成形部的端部置于模具成形部的模具内部,并且未固化的高分子材料注入模具内部时,高压的未固化材料挤压挤压成形部的端部,将挤压成形部的端部推离规定位置。于是,挤压成形部的端部偏离规定位置,模具成形部无法制成正确形状。该问题在例如密封条的基部等模具成形部的厚壁部分特别令人担忧。The conventional weather strip described above has the following problems. That is, when the end of the extruded part is placed inside the mold of the molded part, and the uncured polymer material is injected into the inside of the mold, the high-pressure uncured material presses the end of the extruded part, making the extruded The end of the part is pushed away from the specified position. As a result, the end of the extruded portion deviates from a predetermined position, and the molded portion cannot be formed into a correct shape. This problem is particularly worrisome in thick-walled parts of mold forming parts such as the base of weatherstrips.
实用新型内容Utility model content
本实用新型鉴于上述情况,目的在于提供一种密封条,该密封条能够防止在模具成形部成形时挤压成形部的端部错位。In view of the above circumstances, the present invention aims to provide a weather strip capable of preventing misalignment of an end portion of an extruded molded portion when the molded molded portion is formed.
为了实现上述目的,本实用新型所述的密封条是一种沿着汽车身和汽车门的间隙延伸并将该间隙密封的密封条,所述密封条包括模具成形部,所述模具成形部具有一端和另一端,在一端与挤压成形部接合,模具成形部包括:基部,安装固定在设置于汽车身和汽车门中的任一方上的安装座面上;以及主密封部,从该基部突出并与汽车身和汽车门中的剩余另一方弹性接触。基部具有突部、基面和有底槽部,所述突部设置在模具成形部的宽度方向一侧,沿着模具成形部的长度方向延伸并与安装座面弹性接触,所述基面形成于模具成形部的宽度方向一侧与另一侧之间,面向安装座面或者接触安装座面,所述有底槽部形成于突部和基面之间,从长度方向一端向另一端延伸。In order to achieve the above object, the sealing strip described in the utility model is a sealing strip extending along the gap between the car body and the car door and sealing the gap, the sealing strip includes a mold forming part, and the mold forming part has One end and the other end, at one end engaged with the extruded forming part, the mold forming part comprising: a base mounted on and fixed on a mounting seat surface provided on any one of the vehicle body and the vehicle door; and a main seal part formed from the base Protrude and make elastic contact with the remaining one of the car body and the car door. The base has a protruding part, a base surface and a bottomed groove part, the protruding part is arranged on one side of the width direction of the mold forming part, extends along the length direction of the mold forming part and is in elastic contact with the seat surface, the base surface forms Between one side and the other side in the width direction of the mold forming part, facing the mounting seat surface or contacting the mounting seat surface, the bottomed groove part is formed between the protrusion and the base surface, extending from one end to the other end in the length direction .
根据本实用新型,槽部对应于设置在模具成形部的模具上的突部,模具成形部在与挤压成形部的接合处从基面的外侧挖空。由此,当高压的未固化材料注入模具成形部的模具内部时,未固化材料的压力在槽部附近减弱,从而防止置于接合处的挤压成形部错位。According to the invention, the groove portion corresponds to the protrusion provided on the die of the mold forming portion hollowed out from the outside of the base surface at the joint with the extrusion forming portion. Thereby, when the high-pressure uncured material is injected into the mold of the molded part, the pressure of the uncured material is weakened near the groove part, thereby preventing dislocation of the extruded part placed at the junction.
槽部可以是一个,但作为本实用新型的优选方面,基部还具有:第二突部,设置在模具成形部的宽度方向另一侧,沿着模具成形部的长度方向延伸并与安装座面弹性接触;以及有底第二槽部,形成于第二突部与基面之间,从模具成形部的长度方向一端向另一端延伸。根据该方面,槽部设置有两个,因此未固化材料的压力在两个槽部附近减弱,从而进一步防止置于接合处的挤压成形部错位。There can be one groove, but as a preferred aspect of the present invention, the base also has: a second protrusion, which is arranged on the other side of the width direction of the mold forming part, extends along the length direction of the mold forming part and is aligned with the mounting seat surface elastic contact; and a bottomed second groove formed between the second protruding portion and the base surface and extending from one end to the other end of the mold forming portion in the length direction. According to this aspect, two groove portions are provided, so that the pressure of the uncured material is weakened near the two groove portions, thereby further preventing misalignment of the extruded portion placed at the joint.
作为本实用新型的一个方面,所述汽车门是在汽车的前后方向上进退移动的滑动门。作为另一个方面,车门可以是通过铰链转动的车门。As an aspect of the present invention, the car door is a sliding door that moves forward and backward in the front and rear directions of the car. As another aspect, the vehicle door may be a hinged vehicle door.
密封条划分出一个或多个中空空间。例如,基部中空,主密封部中空,设置分隔壁以将这两个中空空间隔开。分隔壁可以设置在整个长度方向上,或者也可以在长度方向上局部省略。作为本实用新型的优选方面,在基面上形成有狭缝,该狭缝沿着模具成形部的长度方向延伸,与密封条的内部空间连接。根据该方面,在从模具中取出模具成形部时,能够容易地将基部内部的型芯从狭缝中抽出。应予说明,关于模具成形部的长度方向上的位置,也可以不在基面上形成狭缝。The sealing strip demarcates one or more hollow spaces. For example, the base portion is hollow, the main sealing portion is hollow, and a partition wall is provided to separate these two hollow spaces. The partition wall may be provided in the entire length direction, or may be partially omitted in the length direction. As a preferred aspect of the present invention, a slit is formed on the base surface, and the slit extends along the length direction of the mold forming part and connects with the inner space of the sealing strip. According to this aspect, when taking out the mold forming part from the mold, the core inside the base can be easily drawn out from the slit. It should be noted that, regarding the position in the longitudinal direction of the mold forming portion, the slit may not be formed on the base surface.
作为本实用新型的一个方面,模具成形部为密封条的尾部。该尾部可以具有用于安装固定的耳部。作为另一方面,模具成形部可以是密封条的长度方向上的中间部位。As an aspect of the present invention, the forming part of the mold is the tail part of the sealing strip. The tail may have ears for mounting and fixing. As another aspect, the mold forming portion may be an intermediate portion in the length direction of the weather strip.
如上所述,根据本实用新型,在挤压成形部的一端置于模具成形部的模具内部的同时注入未固化的高分子材料时,防止挤压成形部错位。As described above, according to the present invention, when the uncured polymer material is injected while one end of the extruded portion is placed inside the mold of the molded portion, misalignment of the extruded portion is prevented.

基部24和主密封部25均为中空,由规定厚度的橡胶壁形成。它们的内部空间由同样的橡胶材料制成的分隔壁34分隔。在主密封部25的下表面一体地形成有副密封部27。副密封部27是由同样的橡胶材料构成的壁,从主密封部25向下方突出,与车身101弹性接触,将间隙G2密封。间隙G2为主密封部25与车身101之间的间隙。Both the
基部24具有基面26、第一突部28、第二突部29、有底槽部31、32、以及无底狭缝33。基面26是沿着密封部21的长度方向延伸的平坦面,面向或接触安装座面104。第一突部28和第二突部29分别设置在基面26的宽度方向两侧,从基面26突出,沿着密封部21的长度方向延伸。The
槽部31、32从基面26凹陷形成,分别设置在第一突部28与基面26的边界、以及第二突部29与基面26的边界,沿着密封部21的长度方向延伸。狭缝33形成在基面26的宽度方向中央,沿着密封部21的长度方向延伸,贯通基面26的橡胶壁。狭缝33用作取芯孔。
如图3所示,基面26、第一突部28、第二突部29、第一槽部31、第二槽部32、以及狭缝33与接合面23连接。基面26、第一突部28、以及第二突部29从密封部21的一端延伸至另一端。与之相对,第一槽部31和第二槽部32的长度方向尺寸Ld(图2)没有特别限定,比密封部21的长度方向尺寸更短。在本实施方式中,密封部21的长度方向尺寸大于30mm,Ld=30mm。另外,第一槽部31和第二槽部32的槽深度为1.3mm。As shown in FIG. 3 , the
换言之,关于长度方向上的垂直截面积,密封部21在接合面23和靠近接合面23的一端部具有较小的截面积,而在远离接合面23的部位、即耳部22侧的另一端区域具有较大的截面积。In other words, with regard to the vertical cross-sectional area in the longitudinal direction, the sealing
狭缝33的长度方向尺寸也没有特别限定,在本实施方式中从密封部21的一端延伸至另一端。作为未图示的实施方式,狭缝33可以沿着密封部21的长度方向断续地排列。The longitudinal dimension of the
