Description

塑胶模具中集成植绒带的装配结构
技术领域
本发明涉及植绒带装配技术领域，尤其涉及塑胶模具中集成植绒带的装配结构。
背景技术
橡胶植绒密封条在汽车密封条***中占据非常重要的地位。通常应用在门窗玻璃导槽密封条和腰线密封条中，其主要功能是密封和降低风噪。
目前常用工艺方法如下：先将金属骨架根据汽车钣金结构做出相应的弯曲形状，然后再通过注塑模具将骨架覆盖上橡胶再植绒的工艺。传统的植绒方法包括涂胶、静电植绒、固化。在整个工艺中，由于绒毛导电性差、下绒量低、粘合剂厚度不均匀、固化程度不够等因素导致绒毛密度低、绒毛不均、植绒强度差的问题，不但成品率低，而且整个生产工序复杂、繁琐，投入成本较大。
发明内容
本发明旨在解决现有技术的不足，而提供塑胶模具中集成植绒带的装配结构。
本发明为实现上述目的，采用以下技术方案：塑胶模具中集成植绒带的装配结构，包括扣合在一起的型芯Ⅰ和型芯Ⅱ，且型芯Ⅰ和型芯Ⅱ通过若干螺钉固定在一起，型芯Ⅰ和型芯Ⅱ之间形成空腔，型芯Ⅰ和型芯Ⅱ上均设有若干与空腔连通的通孔，型芯Ⅰ上连有与空腔连通的真空接头，型芯Ⅱ上安装有两个水路加长管，水路加长管的外侧端连有水路接头，型芯Ⅰ和型芯Ⅱ之间的空腔内安装有冷却铜管，冷却铜管的两端分别与两个水路加长管的内侧端连接，形成冷却回路。
型芯Ⅰ位于型芯Ⅱ上方，型芯Ⅰ的顶面和型芯Ⅱ的底面均中间低周边高，与空腔连通的通孔位于型芯Ⅰ和型芯Ⅱ的中部，且型芯Ⅰ顶面左侧和型芯Ⅱ底面左侧均设有用于安装金属骨架的一号开口。
型芯Ⅱ底面远离水路加长管的一侧设有二号开口，且二号开口处安装有磁铁。
磁铁安装有一个或若干个。
型芯Ⅱ上安装有固定板，冷却铜管的端部固定在固定板上，且冷却铜管的端部伸出固定板后与水路加长管连接。
与空腔连通的通孔的直径为1mm。
本发明的有益效果是：本发明旨在减少工序，降低成本。将植绒带利用真空吸附在型芯Ⅰ和型芯Ⅱ的型腔表面，将已弯曲成型的金属骨架安装在型芯Ⅰ和型芯Ⅱ上，利用胶料将植绒带和金属骨架连接在一起，完成整个密封条植绒的生产过程。通过使用本发明将注塑成型和橡胶植绒集成于注塑模具中，相较于传统橡胶植绒工艺，减少了大部分工序，节约了生产成本，提高生产效率。

以下将结合本发明的实施例参照附图进行详细叙述。
具体实施方式
下面结合附图和实施例对本发明作进一步说明：
如图1至图2所示，塑胶模具中集成植绒带的装配结构，包括扣合在一起的型芯Ⅰ1和型芯Ⅱ6，且型芯Ⅰ1和型芯Ⅱ6通过若干螺钉7固定在一起，螺钉7安装在型芯Ⅰ1的四周，型芯Ⅰ1和型芯Ⅱ6之间形成空腔，型芯Ⅰ1和型芯Ⅱ6上均设有若干与空腔连通的通孔，与空腔连通的通孔的直径为1mm，型芯Ⅰ1上连有与空腔连通的真空接头2，真空接头2作用是连接外界气源，使型芯Ⅰ1与型芯Ⅱ6的内部形成真空环境，例如真空接头2与外部真空泵连接，使型芯Ⅰ1和型芯Ⅱ6之间的空腔产生负压，将植绒带吸附到型芯Ⅰ1和型芯Ⅱ6上；
型芯Ⅱ6上安装有两个水路加长管3，水路加长管3的外侧端连有水路接头4，型芯Ⅰ1和型芯Ⅱ6之间的空腔内安装有冷却铜管9，冷却铜管9的两端分别与两个水路加长管3的内侧端连接，形成冷却回路，其作用是保证在工作状态下，防止温度过高。
型芯Ⅱ6上安装有固定板5，冷却铜管9的端部固定在固定板5上，且冷却铜管9的端部伸出固定板5后与水路加长管3连接。
型芯Ⅰ1位于型芯Ⅱ6上方，型芯Ⅰ1的顶面和型芯Ⅱ6的底面均中间低周边高，与空腔连通的通孔位于型芯Ⅰ1和型芯Ⅱ6的中部，型芯Ⅰ1和型芯Ⅱ6的中部壁厚均为4mm，且型芯Ⅰ1顶面左侧和型芯Ⅱ6底面左侧均设有用于安装金属骨架的一号开口10，型芯Ⅱ6 底面远离水路加长管3的一侧设有二号开口，且二号开口处安装有磁铁8，磁铁8安装有一个或若干个，用于利用磁力固定金属骨架。
本发明安装在模具内部，工作时，在外界气源的作用下，通过真空接头2使型芯Ⅰ1与型芯Ⅱ6的内部形成真空环境，使植绒带吸附在型芯Ⅰ1与型芯Ⅱ6的表面，C形或U形金属骨架安装在型芯Ⅰ1与型芯Ⅱ6上，且金属骨架的内侧中部位于型芯Ⅰ1与型芯Ⅱ6的一号开口处，金属骨架通过磁铁8固定，防止位移，固定完成后，合模注塑，金属骨架注塑成型与植绒同步完成。
本发明旨在减少工序，降低成本。将植绒带利用真空吸附在型芯Ⅰ1和型芯Ⅱ6的型腔表面，将已弯曲成型的金属骨架安装在型芯Ⅰ1和型芯Ⅱ6上，利用胶料将植绒带和金属骨架连接在一起，完成整个密封条植绒的生产过程。通过使用本发明将注塑成型和橡胶植绒集成于注塑模具中，相较于传统橡胶植绒工艺，减少了大部分工序，节约了生产成本，提高生产效率。
上面结合附图对本发明进行了示例性描述，显然本发明具体实现并不受上述方式的限制，只要采用了本发明的方法构思和技术方案进行的各种改进，或未经改进直接应用于其它场合的，均在本发明的保护范围之内。
