Description

一种旋转脱模的多色车灯注塑模具 技术领域
本发明属于模具技术领域，具体涉及一种旋转脱模的多色车灯注塑模具。
背景技术
随着社会的发展，人们对生活的体验要求也越来越高了，现有的多色车灯越来越受到人们的喜爱。
现有的多色车灯为了能够使车灯发出的光源面积更大，许多多色车灯采用长条状，长条状的车灯由于长度关系，一套模具内通常适合生产一种塑胶原料颜色的产品。现有多色车灯的生产通常是将产品先在一套模具上用一种颜色材料生产完成后，再将产品拿到另一套模具中用另一种颜色材料直接注塑，两次或者多次注塑结合形成一体化结构的产品。一件多色车灯需要多套模具配合才能完成生产，而且需要人员把产品在一套模具注塑完成后，移送到下一套模具，直到多色车灯生产完成。
在上述生产过程中，在前一套模具生产完成后，将产品拿出送至下一套模具并放置在该模具的注塑工位上，然后再使该套模具合模进行下一种颜色注塑，但是在该套模具合模过程中由于模具各部件之间相互配合可能会导致上一套模具形成的产品在该套模具重新合模中位置轻微偏移，下一套模具在上一套模具注塑成形的产品上进行另一种颜色注塑后，不同颜色的成形产品结合处可能会存在一些轻微的位置偏差，从而影响产品的注塑质量。
发明内容
本发明的目的是针对现有的技术存在上述问题，提出了一种旋转脱模的多色车灯注塑模具，本发明所要解决的技术问题是：如何提高多色车灯的注塑质量。
为了解决上述技术问题，本发明采用下列技术方案来实现：
一种旋转脱模的多色车灯注塑模具，包括竖向设置的若干个定模和与定模数量相同的动模，本旋转脱模的多色车灯注塑模具还包括转动件，若干个定模设于转动件上且转动件能够带动若干个定模转动，每个动模均能够与对应的定模合模形成注塑成型腔，所述定模上连接有导向件，所述导向件上滑动连接有斜顶块，所述斜顶块能够沿导向件斜向滑动，所述斜顶块上具有能够与注塑成型腔内成形的工件卡接的卡接部，所述导向件上穿接有可移动的顶杆，所述顶杆与斜顶块连接且顶杆能够驱动斜顶块与注塑成型腔内成形的工件脱离卡接。
对多色车灯进行注塑生产，使其中一个动模与对应的定模合模形成注塑成型腔，其中卡接部位于注塑成型腔的边缘处，把一种颜色的塑胶注入到该注塑成型腔内，工件在该注塑成型腔内成形完成后，工件上形成有与斜顶块卡接部对应的卡接区，工件与斜顶块的卡接部形成卡接固定，然后该合模的动模和定模开模，转动件转动带动该定模转动至下一动模位置。在开模的过程中以及转动件带动定模转动的过程中，斜顶块与顶杆连接，斜顶块与导向件连接，导向件连接在定模上，由于斜顶块、顶杆和导向件三者配合位置固定，斜顶块上的卡接部保持将在上述注塑成型腔成形的工件卡住，使工件在该定模上始终保持位置固定。该定模转动至与下一动模相对的位置时，下一个动模与该定模合模形成另一注塑成型腔，在合模过程中，斜顶块上的卡接部仍然将在上一注塑成型腔成形的工件在该定模上卡住，所以并不会导致由于合模而使已经注塑成形的工件出现位置偏移，因此,在定模上成形的工件始终能够保持定位，把另一种颜色的塑胶注入到该另一注塑成型腔内，在上一注塑成型腔内 成形工件的基础上直接增加另一种颜色的塑胶，使另一种颜色的塑胶材料在注塑成型腔内成形的工件与上一注塑成型腔成形的工件能够无偏差结合，然后根据多色车灯的颜色要求按照上述步骤再依次注入不同颜色材料到该定模与其他对应的动模合模形成的其他注塑成型腔内，直到完成整个产品注塑。
整个加工过程中，在斜顶块卡接部的作用下，该定模和不同动模配合的注塑成形的工件在定模与动模开模过程中、在定模转动过程以及在该定模与其他动模合模注塑的过程中始终能够保持定位，因此，该定模与不同动模配合并注入不同颜色塑胶材料注塑成型的工件均能够实现无偏差结合，从而就提高了产品的注塑质量。产品完成注塑后，在该定模与最后一个动模合模状态下，使顶杆移动，顶杆驱动斜顶块使斜顶块沿导向件斜向滑动，使卡接部与最终完成成形的工件脱离卡接，最后使该定模与最后一个动模开模，把注塑完成的工件取出。
在上述的旋转脱模的多色车灯注塑模具中，所述导向件通过第一螺丝固定连接在定模上，所述斜顶块上具有斜向设置的滑道，所述导向件与滑道配合并能够沿着滑道滑动，所述导向件上具有滑槽，所述斜顶块与导向件之间设有连接块，所述连接块一端插接在斜顶块上，另一端伸入滑槽内并能够在滑槽内移动，所述连接块与顶杆相连。
导向件固定在定模上，斜顶块与导向件通过滑道形成可滑动配合，连接块的两端分别插入到斜顶块中和导向件的滑槽中，而连接块与顶杆相连接，顶杆能够通过连接块驱动斜顶块在导向件上斜向滑动。顶杆不移动的情况下，斜顶块上的卡接部对定模上注塑成型的工件进行固定，需要使卡接部脱离工件解除卡接时，顶杆移动推动连接块，使连接块作用在斜顶块上，斜顶块能够利用滑道在导向件上斜向滑动，斜顶块上的卡接部与工件脱离。顶杆不仅为斜顶块上的卡接部与工件脱离卡接提供了动力，也为卡 接部与工件保持卡接状态提供了保持力，使工件在定模上固定稳定，有利于提高产品的注塑质量。
在上述的旋转脱模的多色车灯注塑模具中，所述连接块一侧具有卡槽，所述顶杆卡接在卡槽内。卡槽的设置使连接块与顶杆连接方便且固定稳定。
在上述的旋转脱模的多色车灯注塑模具中，所述卡槽呈T字形结构，所述顶杆一端具有与卡槽相配合的T字块。呈T字形的卡槽与顶杆一端的T字块配合连接，容易装配且连接稳定，从而使斜顶块的卡接部与工件卡接稳定，使工件在定模上固定稳定，有利于提高产品的注塑质量。
在上述的旋转脱模的多色车灯注塑模具中，所述斜顶块包括滑动块和卡接块，所述卡接块通过第二螺丝固定连接在滑动块上，所述滑道设置在滑动块上，所述滑动块上设有插槽，所述连接块插接在插槽内，所述卡接部位于卡接块上。斜顶块包括分体设置的滑动块和卡接块，可单独加工成型滑动块和卡接块，使滑动块和卡接块制造容易。同时连接块插接在插槽，通过插槽使连接块与斜顶块连接，不仅使连接块能够带动滑动块沿着导向件滑动，还使连接块与斜顶块连接稳定，使工件在定模上固定稳定，有利于提高产品的注塑质量。
在上述的旋转脱模的多色车灯注塑模具中，所述卡接部包括朝注塑成型腔凸出设置的凸块。凸块与工件形成卡接配合，凸块朝注塑成型腔凸出设置，增强了工件与卡接部的卡接效果，使工件在定模上固定稳定，有利于提高产品的注塑质量。
在上述的旋转脱模的多色车灯注塑模具中，所述转动件为转盘，所述转动件上连接有呈竖向设置的安装板，所述安装板的两侧上分别连接有所述定模，每个定模均能够与对应的动模合模形成所述注塑成型腔。转动件带动安装板转动，安装板带动这些定模同步转动，注塑成型腔用于工件注塑成型。通过同一安装板固 定这些定模，使这些定模在安装板的定位准确，保证定模与动模之间合模的准确性，有利于提高成品的注塑质量。
在上述的旋转脱模的多色车灯注塑模具中，所述顶杆穿接在定模上，所述定模与安装板之间设有可移动的顶杆连接板，所述顶杆的另一端与顶杆连接板连接，一端穿过导向件与连接块连接。顶杆连接板用于驱动顶杆移动，顶杆带动连接块，连接块顶压斜顶块，使斜顶块能够沿着导向件斜向滑动并与工件脱离卡接。
在上述的旋转脱模的多色车灯注塑模具中，所述顶杆设置有若干个，每个顶杆均与导向件和斜顶块相配合。多组导向件、斜顶块和顶针配对形成的定位结构能够使工件在定模上固定更加牢靠，有利于提高产品的注塑质量。
在上述的旋转脱模的多色车灯注塑模具中，本旋转脱模的多色车灯注塑模具还包括顶针板，所述顶针板通过驱动件驱动，所述顶针板设置在其中一个动模的侧方，所述顶针板上设有若干个顶针，若干个顶针能够穿过该动模。最后脱模时，驱动件驱动顶针板，顶针板能够带动顶针穿过动模并能够把在注塑成型腔内成形的工件从该动模上顶出。
与现有技术相比，本发明的有益效果是：
定模和不同动模配合注塑成形的工件在定膜与动模开模过程中、在定模转动过程以及该定模与其他动模合模注塑的过程中始终能够保持定位，因此，该定模与不同动模配合并注入不同颜色塑胶材料成形的工件均能够实现无偏差结合，从而提高了产品的注塑质量。

本注塑模具还包括顶针板10，顶针板10设置在第一动模2a的侧方，顶针板10的侧方设有底板一12，底板一12连接于第一模架13上，底板一12与第一动模2a之间通过若干个脚架一14连接，顶针板10位于底板一12与第一动模2a之间，顶针板10固定连接有若干顶针11。顶针板10还与驱动件相连，驱动件的驱动端穿过底板一12和第一模架13，驱动件为气缸或者油缸，驱动件驱动顶针板10使若干个顶针11穿过第一动模2a，顶针11能够将第一动模2a与定模1[第一定模1a和第二定模1b中的任意一个]合模形成的注塑成型腔内注塑完成的产品顶出。第二动模2b侧方设有底板二15，底板二15连接于第二模架16上，第二动模2b和底板二15通过若干个脚架二17连接。
对多色车灯进行注塑生产，使第二动模2b与第二定模1b合模形成注塑成型腔20，第二动模2b与第二定模1b之间的注塑成型腔20为第一注塑成型腔，其中卡接部5a位于第一注塑成型腔的边缘处，且凸块5a1朝向并插入到第一注塑成型腔中，把第一种颜色的塑胶注入到该第一注塑成型腔内，第一种颜色工件21在该第一注塑成型腔内成形完成，第一种颜色工件21上形成有与凸块5a1对应的卡接槽，斜顶块5上的卡接部5a贴靠在工件21上，且凸块5a1嵌入到工件21的卡接槽中，卡接部5a与在第二定模1b上注塑成型的工件21形成卡接，使工件21固定在第二定模1b上，然后第二动模2b与第二定模1b开模，转动件3转动带动第一定模1a和第二定模1b转动，使第二定模1b转动至与第一 动模2a相对的位置，第一定模1a转动至第二动模2b相对的位置，然后第二定模1b与第一动模2a合模形成另一注塑成型腔，第二定模1b与第一动模2a之间的注塑成型腔20为第二注塑成型腔，顶杆6保持不动，斜顶块5上卡接部5a保持将工件21固定在第二定模1b上，接着把第二种颜色的塑胶注入到第二注塑成型腔内，第二种颜色的塑胶在第二注塑成型腔内直接在原工件21上注塑成型，结合成形一体成型结构。由于导向件4固定在第二定模1b上，斜顶块5与导向件4配合，顶杆6与连接块7相连接，连接块7与斜顶块5和导向件4相配合，顶杆6不移动的情况下，斜顶块5上的卡接部5a对第二定模1b上注塑成型的工件21始终保持位置固定，在第二定模1b与第二动模2b开模的过程中、在第二定模1b转动的过程中以及第一动模2a与第二定模1b进行合模形成第二注塑成型腔并进行注塑的过程中，工件21始终保持固定，把第二种颜色的塑胶注入到第二注塑成型腔内与第一注塑成型腔成形的工件21能够无偏差结合，从而就提高了产品的注塑质量。注塑完成后，在合模状态下，顶杆6驱动斜顶块5使斜顶块5与完成成形的工件21脱离卡接，然后第一动模2a与第二定模1b开模，并通过驱动件驱动顶针板10，顶针板10带动顶针11把工件21顶出。在第一动模2a与第二定模1b合模进行第二种颜色塑胶注塑的过程中，另一侧的第一定模1a与第二动模2b同步进行合模形成第一注塑成型腔，且注入第一种颜色的塑胶注入到第一注塑成型腔内，在第一注塑成型腔完成第一种颜色的注塑成型时，通过斜顶块5上的卡接部5a与工件21形成卡接，使工件21固定在第一定模1a上，然后第一定模1a与第二动模2b开模，成形的工件21通过斜顶块5上的卡接部5a保持固定在第一定模1a上，再通过转动件3转动，使第一定模1a和第一动模2a相对，第二定模1b和第二动模2b相对，第一定模1a和第一动模2a合模形成第二注塑成型腔，第二定模1b和第二动模2b合模形成第 一注塑成型腔，并分别注入对应颜色的塑胶进行注塑成形，在第二动模2b处完成成型的产品通过若干个顶针11顶出，转动件3能够带动第一定模1a和第二定模1b实现循环转动，可以进行连续性生产，提高了生产的效率。在第二动模2b完成合模时，与第二动模2b相对的定模1上的顶杆6移动复位，使斜顶块5上的卡接部5a靠近第一注塑成型腔，并使卡块5a1凸出并插入到第一注塑成型腔中，从而使工件21上的卡接槽在完成注塑后自然形成，卡块5a1插入到工件21的卡接槽中与工件21形成卡接。第二动模2b与定模1开模的过程中、第一定模1a和第二定模1b在转动的过程中、第一定模1a或第二定模1b[即任意一个定模1]与第一动模2a合模的过程中，在顶杆6不移动的情况下，斜顶块5上的卡接部5a与工件21保持卡接，始终能够使工件21保持位置的固定，因此，第一定模1a或第二定模1b与对应的动模2配合并注入不同颜色塑胶材料进行注塑生产能够实现无偏差结合，从而提高了产品的注塑质量。
本文中所描述的具体实施例仅仅是对本发明精神作举例说明。本发明所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本发明的精神或者超越所附权利要求书所定义的范围。
