Description

一种汽车前格栅模具拼接式组合脱模机构
技术领域
本发明涉及一种汽车前格栅模具拼接式组合脱模机构，属于注塑模具领域。
背景技术
散热器前格栅是汽车发动机冷却通风用的网格状零件，对汽车局部起到保护、散热、透气及外表装饰的作用。由于格栅位于汽车前部最醒目的位置，其外观质量的要求很高。但是，由于前格栅的面积都比较大，并且前格栅上制有许多的网格孔，目前，在注塑时往往采用单点进浇，但是单点进浇不易控制单点料流量和料流时间，造成浇流不平衡，注塑不足，容易发生填充不足、网格区域变形、困气、熔接线等外观缺陷，严重影响塑件的外观质量和强度；另一方面，汽车前格栅的背面制有较多的安装卡扣和倒扣，而脱模时，往往采用直顶强制顶出，这样不仅会造成脱模困难，而且容易将卡扣和倒扣损坏。
发明内容
本发明的目的是为了克服已有技术的缺点，提供一种采用大滑块与斜顶拼接式组合，不仅能有效提高塑件表面质量，而且可以使产品更容易脱模，提高生产效率的一种汽车前格栅模具拼接式组合脱模机构。
本发明一种汽车前格栅模具拼接式组合脱模机构的技术方案是：包括模具上模板和下模板，上模板下安装流道板，流道板中安装热流道喷嘴，流道板下安装定模板，定模板中安装定模镶块，下模板上安装模脚，模脚上安装动模板，动模板中安装动模镶块，动模镶块与定模镶块之间有注塑成型的前格栅，前格栅的背面制有安装卡扣和倒扣，模脚之间设置上顶板和下顶板，上顶板上连接直顶杆，直顶杆的顶部与安装卡扣相配合，其特征在于所述的动模板的一侧上设置外滑块，外滑块的内壁上拼接内镶块，所述的上顶板上安装斜滑座，斜滑座上连接斜顶杆，斜顶杆上安装斜顶镶块，斜顶镶块与倒扣相配合，并与内镶块之间构成前格栅的侧边模腔，侧边模腔中有前格栅侧边。
本发明的一种汽车前格栅模具拼接式组合脱模机构，主要特点是在动模板的一侧上设置外滑块，外滑块的内壁上拼接内镶块，内镶块与斜顶镶块之间构成前格栅的侧边模腔，侧边模腔中有前格栅侧边，与传统一整块大滑块相比，将大滑块分成内、外两部分后，可分别选取两种质量不同的模料加工后再拼接，解决了由于滑块太大导致一次性加工困难的问题，有效提高了加工精度；并且，与产品部分接触部分的内镶块可采用较好的模料，可大幅度提高模具的使用寿命，节省费用。脱模时，采用斜顶和直顶结合方式，斜顶杆顶在前格栅的倒扣部位，更容易使产品脱模，可减少直顶杆的数量，降低成本。
本发明的一种汽车前格栅模具拼接式组合脱模机构，所述的热流道喷嘴有2—8组，多组进胶实现多点进胶，保证在注塑过程中的浇流平衡，减少熔接痕，使产品表面光洁度较好。每组热流道喷嘴与前格栅的进胶点均呈90°垂直进胶，确保进胶点平整，保证前格栅质量。所述的内镶块与外滑块经螺钉拼接，螺钉拼接方便、牢靠。
