Operating procedures for mold temperature machine

1. Purpose
To standardize the operation of mold temperature machine, control mold temperature and improve product quality.
2. Scope
It is applicable to all kinds of existing oil temperature machines and water temperature machines.
3. Responsibilities
The upper and lower mold technicians of the injection molding department should correctly use the mold temperature machine, connect the oil and water lines, adjust the mold temperature, and keep the machine clean and tidy according to this procedure.
4. Operation process
Read the operating instructions
Familiarize with function keys
Connect oil and water
Startup procedures and precautions
clean and tidy
Routine inspection and troubleshooting
5. Process description
5.1 Read this procedure before use.
5.2 Familiarize yourself with function keys before use.
5.3 Connect oil and water.
5.3.1 Connect the water transportation of the machine and the circulating water circuit of the mold temperature machine in the correct direction.
5.3.2 Connect the heat transfer oil pipe of the mold temperature machine with the mold.
5.4 Startup procedure
5.4.1 Check the stock of medium liquid (oil or water) and replenish it in time.
5.4.2 Set the temperature as required:
Water freezing machine for 8~20 ℃
Normal temperature water at 20~35 ℃
Water temperature machine for 35~85 ℃
Oil temperature machine for 85~160 ℃
5.4.3 Open the inlet and outlet oil (water) valves.
5.4.4 Plug in the power and turn on the POWER switch.
5.4.5 Turn on the pump switch, check the pump running direction is correct, and change the two phase lines when reversing.
5.4.6 Turn on the HEATER electric heat switch and turn on the electric heat.
5.4.7 When stopping production, first turn off the electric heating of the mold heater, cool it to below 60 ℃, turn off the power supply, remove the oil pipe, make the oil return to the mold heater, turn off the valve, do not turn off the valve first, do not turn off the pump and electric switch, which is very dangerous.
5.5 Precautions
5.5.1 It is forbidden to mix water temperature machine and oil temperature machine
5.5.2 It is forbidden to add other hydraulic oil into the oil temperature machine, and the heat medium oil must be used.
5.5.3 The oil temperature machine shall use Teflon pipe, and other water pipes shall not be used.
5.5.4 Before connecting the oil heater, the water in the mold and piping must be blown clean.
5.5.5 When replenishing hot oil, it must be confirmed that the liquid level is within the upper and lower limits of the oil level gauge. If it is too low, it will alarm, and if it is too high, it will not start, and the hot medium oil will flow out, causing danger and waste.
5.6 Clean and tidy
After work, keep the ground and machine clean and tidy.
5.7 Routine inspection and troubleshooting
5.7.1 Patrol the machine frequently to check whether the mold temperature machine has oil leakage and improve it.
5.7.2 "OVER HEAT" alarm indicates that the electric heating is too high and exceeds the safety limit, and the temperature needs to be reduced.
5.7.3 "MEDIUM SHORTAGE" alarm indicates that the mold temperature machine is short of oil (water) and needs to be supplemented immediately.
5.7.4 "OVER LOAD" alarm indicates that the oil pump is overloaded and needs to be checked and cleaned.
5.7.5 "MOTOR RELEASE" alarm indicates that the motor is reversed, check the circuit and rewire.
5.7.6 When checking the oil in the oil cylinder, use a flashlight instead of an open flame.
