The invention relates to the field of injection molding and discloses an injection molding machine. The injection molding machine comprises a glue injection cylinder operation module, a glue injectionmodule, a position sensing module, a pressure detection module and a main control module based on a real-time operation system; the glue injection cylinder operation module is used for driving a glueinjection cylinder to move towards or away from an injection mold; the glue injection module is used for extruding glue in the glue injection cylinder to inject the glue into the injection mold; theposition sensing module is used for sensing the glue injection cylinder in a position with a first preset distance from the injection mold; the pressure detection module is used for detecting the glueinjection pressure of the glue injection module; the main control module is connected with the glue injection cylinder operation module and the glue injection module respectively, and also connectedwith the position sensing module and the pressure detection module respectively, and the main control module is used for controlling the glue injection cylinder operation module and the glue injectioncylinder in real time according to the glue injection pressure detected by the pressure detection module; the main control module, the position sensing module and the glue injection cylinder operation module form a first closed control loop; and the main control module, the pressure sensing module and the glue injection module form a second closed control loop.
Description
technical field [0001] The invention relates to the field of injection molding, in particular to an injection molding machine. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment for making thermoplastic or thermosetting materials into various shapes of plastic products using plastic molding molds. Injection molding is realized through injection molding machines and molds. In the prior art, injection molding machines are generally driven by hydraulic pressure, and the control precision is not high, resulting in low stability and accuracy of injection, which cannot meet the actual production needs.
