Description

一种国标电源线一体式内架热塑成形工艺
技术领域
    本发明涉及国标电源线插头注塑成形领域，具体属于一种国标电源线一体式内架热塑成形工艺。
背景技术
    电源线在按要求尺寸裁断后，将一端进行气剥、端子压接，再将压接好端子的三根芯线分别插入一种PBT塑料材质的内架中，然后放入注塑机中注塑成形。
不足之处：
电源线在气剥后，芯线分别压接完端子，由人工逐一将压接好端子的芯线插入内架中，再放入模腔中注塑。直接弊端是人工将压接好端子的芯线插入塑料内架中，由于人工操作熟练程度及使用力度不一，容易出现端子装入内架中未到位，露出的端子五金尺寸不符合国家标准GB1002-2008统一尺寸要求。另外工艺流程分为“裁线—端子压接—装配内架—注塑”四个步骤。
发明内容
本发明的目的是提供一种国标电源线一体式内架热塑成形工艺，解决了由人工装配导致外露端子五金尺寸不标准的不良现象，由机器操作完成，省去了后来由人工装配的步骤，并且由机器进行统一标准化控制电源线插头的五金尺寸。
本发明的技术方案如下：
一种国标电源线一体式内架热塑成形工艺，包括以下操作步骤：
1将端子1与PBT材料放一起用模具热塑成形，热塑成形为一体式内架2；
2将电线3与一体式内架2通过机器压接形成连接，成为半成品；
3根据产品工艺设计要求，选择相应的模具，打开电源，调至适当温度范围，温度控制范围：前档170±20℃、中档175±20℃、后档180±20℃，压力控制范围：总压100±10㎏/㎝2，第一次注塑压力为65±10㎏/㎝2，第二次注塑压力为40±10㎏/㎝2，保压40±10㎏/㎝2，高压阶段时间为2.5±1.5s，射出时间为10±3.5s，冷却时间为6±4s；
4将步骤2)的半成品放入模腔中，加入PVC胶料，排好线，双手按住自动关模开始进行注塑，开模后双手拿线取出电源线插头产品。
本发明设计成一体式内架后，压好芯线后，无需插内架，直接可以放入模腔中注塑，放入模腔后，也无需按压，即可启动开关，注塑成型。即在PBT塑料骨架热塑成形环节时，将端子放入其中进行固定热塑为一体式。由机器操作完成，省去了后来由人工装配的步骤，并且由机器进行统一标准化控制电源线插头的五金尺寸。

图1为本发明的工艺流程图。
具体实施方式
参见附图，一种国标电源线一体式内架热塑成形工艺，包括以下操作步骤：
1将端子1与PBT材料放一起用模具热塑成形，热塑成形为一体式内架2；
