| In view of the defects such as the underfill and deformation of the plastic parts in the process of thin wall injection molding by standard servo
injection molding machine, that the reason is the injection speed cannot meet the molding conditions. A hydraulic control system for high speed response of servo injection mold machine
was proposed by means of adding modular hydraulic control system to the standard servo injection molding machine. The proportional pressure valve, pressure sensor and direction valve
were used to replace the servo control of the output pressure of the original electric motor pump. The servo motor start acceleration response speed was improved and a high speed
response injection hydraulic system with a servo motor start acceleration time of zero was established. The research show that the defects of thin wall injection molding can be improved
without increasing the power capacity. |
