Installation of Toshiba Injection Molding Machines
1. Outline
This manual defines the installation procedure of electrically driven injection
molding machines for delivering them to the customer under optimum condition.
2. Application
This manual applies to EC30SXⅡ-EC230SXⅡ series injection molding machines.
3. Work Procedure
3-1 Mechanical unit
3-2 Machine weight
Refer to the following list for machine weight.
3-3 Li f t ing positions of forklift
When moving the machine by a forklift, set forks at A and B positions and lift the machine.
3-4 Electric parts and equipments
(1) Connection of power source
Observe the following precautions to connect the power source.
(a) Check for correct wiring since wrong connection may reverse motors. You
may check the wiring with direction of nozzle movement.
(b) Check terminal blocks and cable connectors of electric equipments for loose
bolts.
(2) Precautions (as per instruction manual)
(a) Grounding work
Complete grounding work. Installation grounding of resistance below RΩ.
R=100Ω at ≦AC300V
R=10Ω at ＞AC300V
(b) Installation of circuit breaker
Install a circuit breaker on the power side of or inside the power switchboard. The circuit breaker should be of medium-sensitivity and high-speed type (100 mA) to meet inverter, or equivalent type.
4. Fixing way of machine at transportation
Fix the machine by using wires through fixing holes of machine frame at clamping end face and injection end face.
5. Hazard Warnings
(1) Never enter the area under the machine being lifted with a crane.
(2) Do not remove fixing bolts of injection and clamp units before installation is completed.
(3) Do not perform other work not related to body mounting before installation is
completed.
Safety of Toshiba Injection Molding Machines
1. Three Principles Regarding Safety
Since the injection molding machine allows large mold clamping and injects melted resin at high temperatures, unexpected contingencies can occur. However, contingencies can generally be prevented through the daily checking of safety devices and proper operation. The structure, function and safety features of the machine must be thoroughly understood prior to machine handling, operation, and maintenance.
Strictly observe the following three safety rules to operate the machine safely.
[1] Be absolutely sure that the safety gate is opened before placing your hands into the mold.
[2] Always be sure to turn OFF the power supply before placing the upper part of your body or entering between the mold platens. [3] Do not touch any moving portion of the machine.The above three safety principles are the most important regarding safe operation.
These principles should take precedence over all others.
Please contact our service department if there are any points in this instruction manual which are not completely clear.
