Abstract

本发明公开了一种注塑工艺，包括下列步骤：(1)在热转印网布上使用热转印涂料印刷需要的图案，印刷完成后固化干燥；(2)将热转印网布放置在模具内层需要转印的位置；(3)将模具加热，在模具内腔内注入蒸汽，注满后保持压力并将注入蒸汽的注入口封闭。本发明的方法能够达到一次性完成多色产品的成型和着色的效果，而且有几个颜色都不会增加产品的成本，大大提高了工作效率；其制成品的表面光泽度好于通过现有的注塑生产工艺生产的成品，光泽度达到94度以上，减少了产品喷涂的步骤，进一步节省了生产成本，提高了经济效益。

Description

一种注塑工艺
技术领域
本发明涉及一种注塑工艺，属于化工生产领域。
背景技术
注塑机是一种能一次成型外型复杂、尺寸精确或带有金属嵌件的质地密致的塑料制品的机器，被广泛应用于国防、机电、汽车、交通运输、建材、包装、农业、文教卫生等各个领域以及人们日常生活之中。注射成型工艺对各种塑料的加工具有良好的适应性，生产能力较高，并易于实现自动化。在塑料工业迅速发展的今天，注塑机不论在数量上或品种上都占有重要地位，从而成为目前塑料机械中增长最快，生产数量最多的机种之一。而现有注塑机却只能生产半成品，然后再根据产品要求进行的着色，并且只能一次加一个色，造成生产成本高，工作效率低。
发明内容
针对现有技术存在的不足，本发明所要解决的技术问题是，提供一种注塑工艺，可一次性做成着色产品，节约成本，提高工作效率，并且有效的提高了成品表面的光泽度。
为解决上述技术问题，本发明采取的技术方案是，一种注塑工艺，包括下列步骤：
(1)在热转印网布上使用热转印涂料印刷需要的图案，印刷完成后固化干燥；
(2)将热转印网布放置在模具内层需要转印的位置；
(3)将模具加热，在模具内腔内注入蒸汽，注满后保持压力并将注入蒸汽的注入口封闭；
(4)加热的同时，在模具中同时注入两种不同物质热熔后的熔浆流，一种为ABS塑料，一种为PMMA(聚甲基丙烯酸甲酯)；
(5)将ABS塑料和PMMA注满后，保持住压力并且停止对模具的加热，加热时间为10分钟；
(6)将模具冷却，温度降至70摄氏度时开模，取出成品。
优化的，上述注塑工艺，所述步骤(1)中的固化干燥的温度为82摄氏度，干燥时间小于50分钟。
优化的，上述注塑工艺，所述步骤(4)中ABS塑料和PMMA的熔浆流的温度分别为300摄氏度和350摄氏度。
优化的，上述注塑工艺，所述步骤(4)中ABS塑料和PMMA的重量比为1∶1。
本发明的方法能够达到一次性完成多色产品的成型和着色的效果，而且有几个颜色都不会增加产品的成本，大大提高了工作效率；其制成品的表面光泽度好于通过现有的注塑生产工艺生产的成品，光泽度达到94度以上，减少了产品喷涂的步骤，进一步节省了生产成本，提高了经济效益。
具体实施方式
本发明为一种注塑工艺，包括下列步骤：
(1)在热转印网布上使用热转印涂料印刷需要的图案，印刷完成后固化干燥；
(2)将热转印网布放置在模具内层需要转印的位置；
(3)将模具加热，在模具内腔内注入蒸汽，注满后保持压力并将注入蒸汽的注入口封闭；
(4)加热的同时，在模具中同时注入两种不同物质热熔后的熔浆流，一种为ABS塑料，一种为PMMA(聚甲基丙烯酸甲酯)；
(5)将ABS塑料和PMMA注满后，保持住压力并且停止对模具的加热，加热时间为10分钟；
(6)将模具冷却，温度降至70摄氏度时开模，取出成品。
步骤(1)中的固化干燥的温度为82摄氏度，干燥时间小于50分钟。
步骤(4)中ABS塑料和PMMA的熔浆流的温度分别为300摄氏度和350摄氏度。
步骤(4)中ABS塑料和PMMA的重量比为1∶1。
本发明的方法能够达到一次性完成多色产品的成型和着色的效果，而且有几个颜色都不会增加产品的成本，大大提高了工作效率；其制成品的表面光泽度好于通过现有的注塑生产工艺生产的成品，光泽度达到94度以上，减少了产品喷涂的步骤，进一步节省了生产成本，提高了经济效益。
当然，上述说明并非是对本发明的限制，本发明也并不限于上述举例，本技术领域的普通技术人员，在本发明的实质范围内，作出的变化、改型、添加或替换，都应属于本发明的保护范围。
