Description

一种具有内植骨架的汽车内饰顶棚生产模具
技术领域
本发明涉及汽车零件生产模具领域，更具体地说，涉及一种具有内植骨架的汽车内饰顶棚生产模具。
背景技术
汽车内饰顶棚安装于汽车驾驶舱顶部，起到隔热、隔音与美化装饰的作用。在越来越追求高性能、环保型、节能型、轻量化、个性化的时代，汽车的内饰与汽车的外形一样，成为人们选购汽车的一个重要因素。因此个性化的趋势越来越强烈、对汽车内饰件的要求也越来越高。
目前，PU+GF+PET结构的乘用车内饰顶棚有两种加工工艺，使用PE或PP粘结的热塑性干法工艺和使用PU反应成型的热固性湿法工艺。其中干法工艺一直是分两步完成，即先将PU、GF和PET结合生成三明治基材，然后再加热软化并冷压成型。
现有技术中，汽车顶棚干法成型分为两步，第一步将无纺布PET铺在最下层，然后在无纺布上切撒玻纤GF和PE胶粉或PP胶膜，再铺上PU板材，然后再切撒玻纤GF和PE胶粉或PP胶膜，形成三明治结构的材料叠加。叠加成的复合材料送入加热炉加热至270-330℃，使PE胶粉或PP胶膜融化，然后再送入冷却板，使PE胶粉或PP胶膜冷却至20-30℃固化，将复合材料中的各种组成粘结在一起，并使用压力使其粘结牢固，形成基材。
单目前的汽车内饰顶棚大多都是之间使用PUH和PET等材料复合压制制成，虽然较轻便，但其强度往往不足，受到外部作用力时容易破损，而目前没有一种可生产结构稳定、轻便且具有高强度的汽车内饰顶棚的模具。
发明内容
1．要解决的技术问题
针对现有技术中存在的问题，本发明的目的在于提供一种具有内植骨架的汽车内饰顶棚生产模具，它可以实现通过两个上模具依次与一个模具合膜，生产制成具有钢骨架的内饰顶棚，钢骨架由脊梁和多个翼梁组成，通过翼梁缓冲承受的作用力，通过脊梁保证内饰板整体形状稳定，且钢骨架被高柔性环氧树脂包覆，既提高了内饰顶棚的强度，且内饰顶棚各层之间具有良好的粘结力，具有良好的结构稳定性。
2．技术方案
为解决上述问题，本发明采用如下的技术方案。
一种具有内植骨架的汽车内饰顶棚生产模具，包括滑轨和一对支架，所述滑轨与支架之间连接有一对支撑钢梁，所述滑轨内滑动的连接有下模具，所述滑轨的一端固定连接有电动推杆，所述电动推杆的伸缩端与下模具固定连接，一对所述支架之间安装有固定板，所述固定板上固定连接有一对气缸，两个所述气缸的伸缩端上分别连接有第一上模具和第二上模具，所述支架的外壁上固连接有与支撑钢梁相匹配的滑块，所述支撑钢梁的底端固定连接有电动机，所述电动机的动力输出端上固定连接有螺纹管，所述滑块与螺纹杆螺纹连接，可以实现通过两个上模具依次与一个下模具合膜，生产制成具有钢骨架的内饰顶棚，且钢骨架被高柔性环氧树脂包覆，既提高了内饰顶棚的强度，且内饰顶棚各层之间具有良好的粘结力，具有良好的结构稳定性。
一种具有内植骨架的汽车内饰顶棚生产模具，其使用方法为：
A1使用胶衣喷枪在内饰顶棚生产模具的应用面上均匀地喷涂胶衣；
A2，待胶衣面固化后在下模具内铺设基材；
A3，在基材上架设内植骨架，使钢制脊梁1101与基材层12贴合，并使用喷胶辅助固定；
A4，将第一上模具与下模具合膜，通过第一上模具向模腔中注入树脂；通过注入树脂使内植钢架被树脂覆盖，使基材上形成钢骨架与树脂混合层；
B1，待A4步骤中产出的工件冷却至室温后，技术人员控制电动推杆工作，使滑轨与第二上模具的位置匹配，再在A4中制成的工件上铺设涂布了强力胶粘合剂的面料层；
B2，技术人员控制气缸使第二上模具与下模具合膜，使工件被压制成型，工件冷却后脱模形成带有内植骨架的内饰顶棚；
B3，对内饰顶棚进行表面处理和修边。
进一步的，所述内植骨架包括钢制脊梁，所述钢制脊梁上固定连接有多个对均匀分布的定位锥，所述定位锥上固定连接有钢制翼梁，所述钢制脊梁的上端固定连接有多个均匀分布的缓冲凸台，钢骨架由脊梁和多个翼梁组成，通过翼梁缓冲承受的作用力，通过脊梁保证内饰板整体形状稳定，通过内植骨架作为内饰顶棚的结构强化结构，可增强内饰顶棚的强度。
进一步的，所述基材层为复合基材，所述复合基材由pet无纺布层、玻纤层和PU板层通过PE胶粉高压复合制成，所述树脂为高柔性环氧树脂，通过复合基材内的玻纤层和PU板层保证内饰顶棚的整体硬度和韧性，使内饰顶棚不易破损，使用高柔性环氧树脂作为基材层与面料层之间的填充层，可使内饰顶棚整体保持一定韧性，同时易于缓冲部分内饰顶棚所受的应力。
进一步的，所述下模具内安装有冷却水循环机构和自动加热控制***，易于调控模具合模后的温度。
