以注射成型为代表的“3D复印”技术,以其“低成本、高效率”的模塑成型方式,成为塑料制品加工成型中最重要的方法之一。分析了现有三板式注塑机和二板式注塑机的优劣,并开发出新一代精密三板式注塑机(G2.0)。研发的动模板平行度自动调节装置能够自适应零间隙合模,使舍模系统具有开合模精度高、无需调模等优点;研发的场协同螺杆,使塑化系统具有强化传热传质、混炼效率高、塑化质量好、节能等优点;同时,基于聚合物的PVT特性,开发出注塑制品缺陷在线诊断与自愈调控系统。该新型精密三板式注塑机既保留了传统三板机的优势,又弥补了其合梗精度低的不足,具有合模精度高、自适应调模、塑化质量好等优点,能够满足精密制品的成型要求,市场发展前景广阔。
Injection molding as the representative of the “3D copy ” technology, with its “low cost, high efficiency ” molding method, plastic processing become one of the most important methods. The advantages and disadvantages of the existing three-plate injection molding machine and two-plate injection molding machine are analyzed, and a new generation of precision three-plate injection molding machine (G2.0) is developed. R & D dynamic parallel plate automatic adjustment device can adapt to zero-gap clamping, the mold system has a high precision mold opening and closing, no need to adjust the mold and so on; R & D field synergies with the screw, plasticizing system with enhanced heat and mass transfer , High mixing efficiency, good plasticizing quality, energy saving, etc. Meanwhile, based on the PVT characteristics of the polymer, an on-line diagnosis and self-healing control system for injection molded products was developed. The new precision three-plate injection molding machine not only retains the advantages of the traditional three-plate machine, but also makes up for the lack of accuracy of its co-stems, with high precision clamping, adaptive mold, plasticizing good quality advantages to meet the precision products Molding requirements, the market has broad prospects for development.
