Interface standard of injection molding machine and manipulator

The interface between the injection molding machine and the manipulator is a handshake protocol that coordinates the sequential actions of the injection molding machine and the manipulator. The interface defines the mechanical installation method and the electrical protocol. At present, the most widely used domestically recognized standards are Euro 12 and Euro 67. There are many injection molding machine manufacturers in China, but there are various electrical protocols for manipulator interfaces.

At present, most injection molding machines are equipped with a 32-core interface seat. The following tests must be done before using the manipulator:
1. Turn on the "connect injection molding machine" signal, check whether the injection molding machine can open and close the mold ejector core pulling action, it should not be able to move. Turn off this signal, the injection molding machine should be able to move freely.

2. Put the manipulator in manual mode and open the safety door of the injection molding machine. At this time, a "safe door open" signal should appear, and no action can be taken. This message should disappear after closing the safety door.

3. In manual mode, the manipulator enables the opening and closing of the mold to see if the injection molding machine can open and close the mold. When the opening and closing of the mold is completed, check whether the opening and closing of the mold is completed on the manipulator interface. Check the thimble and core pulling in the same way.

4. In manual mode, do not enable mold opening and closing, see if the injection molding machine can open and close the mold, it should not be able to open and close the mold. Check the thimble and core pulling in the same way.

5. In manual mode, move the manipulator to the mold area to see if it can do the mold clamping action, it should not be possible to close the mold.


The interface is the language for communication between the injection molding machine and the robot. The currently popular common interface languages ​​are European Standard 12 and European Standard 67. If injection molding machine manufacturers, robot manufacturers, and users can follow this language, it will give the three Come easy.
