技术领域
本发明涉及模具，尤其涉及一种汽车组合仪表护罩模具。
背景技术
汽车组合仪表护罩是汽车组合仪表总成的重要组成部分，组合仪表护罩所在的位置在驾驶侧最显眼的位置，对组合仪表起到聚光、挡光以及装饰的作用，对零件变形、外观要求比较高。采用注塑成型是汽车组合仪表护罩一种较为常见的成型方法。然而，通常组合仪表护罩产品与组合仪表显示器匹配边造型常为翻边结构，此翻边分型线不允许出现缺口、变形等缺陷问题。为保证此边界符合要求外观及匹配要求，避免此边界注塑顶出缺陷，仪表护罩模具不在此边界布置顶出结构，靠外侧产品面的斜顶及直顶完成顶出，容易出现容易顶出不平衡、产品结构顶出拉伤、断裂问题。

下面结合附图说明及具体实施方式对本发明作进一步说明。
如图1至图9所示，一种汽车组合仪表护罩模具，包括从上至下层叠设置的定位圈7、隔热板1、型腔锁模板8、热流道板9、型腔(即凹槽)10、型芯(即凸模)11、模脚12、顶针面板13、顶针垫板14和型芯锁模板15，热流道板9上设有热流道系统2，型腔10上设有型腔冷却系统3，型芯11上设有型芯冷却系统4，所述汽车组合仪表护罩模具还包括顶出复位系统5和行程形状6。
如图2所示，所述汽车组合仪表护罩模具在中间仪表护罩产品与组合仪表显示器匹配边区域设计整体顶块顶出，避免顶出中间分型线缺陷，采用直顶块镶件在型芯中配合，具体为，提供中间整体直顶机构，该中间整体直顶机构包括中间整体直顶镶块16、直顶水路18、直顶导向块19和直顶杆20(两根)。
在中间整体直顶镶块16设计直顶水路18，实现独立水冷，避免模具冷却不均匀及顶块顶出卡滞。
直顶水路18在中间整体直顶镶块16上，与外部设备水路连通，直顶杆20固定处使用胶圈避免斜顶头漏水。
中间整体直顶镶块16与直顶杆20通过销钉固定，直顶杆20通过螺丝固定在顶针垫板14上。
中间整体直顶机构跟随顶针垫板14运动，注塑机顶出系统带动顶针板及顶针垫板14运动至顶出行程限位处(限位柱33与型芯11背面贴合)，完成顶出动作，产品可取件；注塑机复位系统带模具顶出系统复位时，该中间整体直顶机构跟随顶针垫板14退回至初始位置，顶出复位动作完成。
针对卡扣斜顶空间不足结构，设计强脱顶出结构，该强脱顶出结构包括拉杆23、扣机结构(扣机滑座24、扣机压条26、弹簧25)、顶杆结构(强脱导向块22、强脱顶杆21、顶杆固定座27)。
强脱顶杆21、拉杆23固定在型芯锁模板15上，扣机结构固定在顶针垫板14上，强脱导向块22固定在型芯11背部，拉杆23头部设计导入斜面29，导向插入型芯11背部。
所述型芯锁模板15上设有一级顶出行程限位凹槽30，所述强脱顶杆21上设有与所述一级顶出行程限位凹槽30相配合的一级顶出行程限位凸块31，该顶出行程限位凸块31具体可设置在顶杆固定座27的底部。
一级顶出时，所述顶针垫板14向上顶出，此时扣机滑座24插入锁定凹槽32内，使得顶针垫板14带动强脱顶杆21向上顶出，从而将汽车组合仪表护罩17的倒扣结构顶出，使汽车组合仪表护罩17的倒扣结构具备了脱出的变形空间，此时，卡扣结构28背部已与型芯11离空，让出产品强脱变形空间，模具继续顶出，二级顶出时，当强脱顶杆21的一级顶出行程限位凸块31受到一级顶出行程限位凹槽30的限制而停止时，顶针垫板14继续向上顶出，在脱出凹槽32的作用下，扣机滑座24压缩弹簧25，使得扣机滑座24脱出锁定凹槽，由于一级顶出行程限位及扣机脱出，二级顶出过程中，强脱顶杆21及拉杆23不随模具顶出系统运动，倒扣结构在二级顶出过程中顶出， 带动产品卡扣变形脱出，模具完成顶出至全部顶出限位(限位柱33与型芯11背面贴合)后，产品可进行取件。
该强脱顶出结构复位时，注塑机复位系统带动顶针垫板14回退至一级顶出限位位置，模具继续复位，扣机在弹簧25的作用下复位至初始位置，顶出系统完成复位。
本发明提供的一种汽车组合仪表护罩模具，具有以下优点：
1)该组合仪表护罩中间整体顶块结构保证了关键特征分型面连贯完整性，避免了分型面不连贯出现的分型线段差、边缘缺口的外观缺陷。
2)该组合仪表护罩模具通过中间整体顶块与产品结构上的斜顶、顶针共同配合，实现了模具整体顶出平衡。
3)该组合仪表护罩模具中间整体顶块设计独立冷却水路，避免模具过热导致顶块卡滞问题，同时保证模具冷却均匀、零件尺寸稳定。
4)该组合仪表护罩模具使用强脱结构实现了窄空间内倒扣结构脱模。
5)该组合仪表护罩模具通过使用二级顶出结构，使强脱零件有变形空间，有效避免强脱失败，零件良品率低。
6)该组合仪表护罩模具的强制顶出结构适用性强，可广泛运用于存在斜顶倒扣量小、斜顶后退空间不满足的模具中。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。

  5. 根据权利要求3所述的汽车组合仪表护罩模具，其特征在于：所述扣机机构包括扣机滑座、扣机压条和弹簧，所述扣机压条有两个并分别位于所述扣机滑座的两侧，所述扣机压条与所述扣机滑座为导向装配，所述扣机滑座、扣机压条分别设置在所述顶针垫板上，所述强脱顶杆上设有锁定凹槽，所述扣机滑座的一端设置在所述锁定凹槽内，所述扣机滑座的另一端通过所述弹簧与所述顶针垫板连接，所述拉杆上设有脱出凹槽，所述 扣机滑座上设有供所述拉杆穿过的通孔，在所述弹簧的弹力作用下，所述通孔的孔侧贴合在所述脱出凹槽上。
  6. 根据权利要求5所述的汽车组合仪表护罩模具，其特征在于：所述型芯锁模板上设有一级顶出行程限位凹槽，所述强脱顶杆上设有与所述一级顶出行程限位凹槽相配合的一级顶出行程限位凸块，一级顶出时，所述顶针垫板向上顶出，此时扣机滑座插入锁定凹槽内，使得顶针垫板带动强脱顶杆向上顶出，从而将汽车组合仪表护罩的倒扣结构顶出，使汽车组合仪表护罩的倒扣结构具备了脱出的变形空间；二级顶出时，当强脱顶杆的一级顶出行程限位凸块受到一级顶出行程限位凹槽的限制而停止时，顶针垫板继续向上顶出，在脱出凹槽的作用下，扣机滑座压缩弹簧，使得扣机滑座脱出锁定凹槽，此时，强脱顶杆和拉杆保持停止，而顶针垫板继续向上顶出，从而带动直顶杆向上顶出，使得中间整体直顶镶块将汽车组合仪表护罩顶出，完成汽车组合仪表护罩的脱模。
  7. 根据权利要求5所述的汽车组合仪表护罩模具，其特征在于：所述脱出凹槽的槽侧为斜面。
