Injection molding machine, as a kind of high voltage, mechanical movement, the hydraullc system of high speed, the safety in production has become an important factory of essential.
The safety circuit of the injection molding machine must meet the following requirements:
A: After the emergency stop is relesed, the machine cannot start suddenly.
B: The safety ciruit of the machine is faulty, and the machine power supply can be stopped.
C: safety circuit failure', the machine cannot start again.
In injection molding machine circuit applications, it is usually used for relays, which we call safety relays. Play the role of safety protection in the circuit, the main purpose is to protect the safety of machine operators. Role in the application from the intermediate relay and time relay.
CHENZHU safety relay CZSR8001-3A1B is suitabale for the application of E-stop button and safety gate, with 3 safety output contacts(N/O) and 1 auxiliary output contact(N/C). It can be operated in single or double chanel mode, manual or automatic reset, and with the function of monitoring the short circuit between channels.
The safety control system of injection moulding machine is consisted of safety gate, E-stop button and safety relay. The hazard is mainly from the squeeze of mould-shutting action. The hazard area is isolated from the operators via safety gate. When the safety gate is closed, the mould-shutting action starts (motor runs). Once the safety gate is opened, the mould-shutting action stops (motor stops).
