Equipment installation:
Necessary facilities
Electricity, cooling water, compressed air, lead fume ventilation pipe for exhaust.

(Technical parameters: power 50kwh ，compressed air 0.1m3/min, 0.6MPa; water consumption 240l/h)

Concrete Floor
As die casting machine is horizontal type, the cement floor must flat. Concrete deepth at least 100mm.

Cooling water
Cooling water is used to cool the mould and the oil. Normal water, circulating water is allowed. If the die casting grid has flash and burr, need to increase the die locking pressure . The locking pressure should be adjusted slowly. Same time the system pressure also be adjust. And to find the appropriate value.

Battery Plate Grid Casting Machine Equipment components:
1. Lead Pot
Lead pot consist: lead pump, injection cylinder, heating pipe, pot body, and heat preservation layer, etc.

Lead pot capacity:1800kg

specifications：380V、6KWX6=36KW

2. Machine Mold Locking Mechanism
The mould locking system consist of locking cylinders, the mold release cylinders and the mould plate.

3. Grid Die Casting Mould
Mold material:H13 steel

Mold size: 35 thick X360 wide x620 long mm

Place the mould to the fixed position with lifting tool, fixed the mould, connected with the heating pipe and the thermocouple.

4.Grid Cutting Machine
Spine cutting machine drives by compressor. Cutting blade material is T8 or 45# steel.

Type 500 Battery Positive Spine/Grid Pressure Die Casting Machine Operating procedures:
1.Before work, to check the reliability of the connection of water, electricity, etc. of equipment。

2.Open power control cupboard door, close the main power switch and the separate switch;

3.Start the power, select manual state to check mold moving, mold locking action.Don't oprate injection action at this time.

4.Turn on the lead pot heating switch. The lead pot heating takes about 2.5 hours.

5.Lead pot temperature heated to about 350 degrees, then to heat the mold and nozzle.

6.When all the temperatures are up to the required values, start the trial run of the equipment. Before starting the machine, check whether the lead melts at the nozzle with steel bars. Manual operation , check the machine. If there is no fault, automatic cycle can be started.

7.After grid picked up from die cavity, it is necessary to check and clean the impurities in the mold.

If the casted grid is not full, has flash or burr, the system pressure and the injection pressure should be adjusted. The general adjusting rule is that the injection pressure should be increased when the grid is not full, the locking pressure should be increased when the flying edge is unsatisfied.

8.When the grid sticks in the mould cavity, the mold release agent should be used.

9.when the mold nozzle temperature is too high, damp cloth or spray gun can be used to cool nozzle localized.

Battery Spine Casting Machine Equipment maintenance and repair (T500):
Die casting Machine is metallurgical equipment, it is working in high temperature and adverse impact environment. Regular maintenance and repair of equipment is necessary, the specific matters are as follows:

1.Hydraulic system
The common failures of hydraulic system of the equipment are:

Causes

Reason

Solutions

Pressure is insufficient or unable to fall



Overflow valve blockage

Clean



The reversing valve does not act and the middle position is not locked.

Reversing valve clogging

Clean

High oil temperature

Low cooling water pressure or high temperature.

Relief valve not unloading

Increase the pressure

Check relief valve

Oil leaking

The seal is broken or loosened.

Remove and replace gaskets

Oil leakage of mould moving cylinder

Leakage is sealed or broken.

Replace seal or cylinder.

The motor or pump has a lot of noise.

Motor bearing damage

Oil pump damage

Replacement bearing

Repair or replace

Low oil level


Add oil

After adjustment, the grid can not be fill full.

Insufficient pressure on accumulator

90 Mpa for nitrogen storage of accumulator

System without pressure

The unloading switch is not closed.


When the hydraulic system is repaired, the unloading switch in front of the accumulator must be loosened. And the oil in the system must be discharged into the oil tank to avoid oil spilling out. Please confirm that the switch is off before turning on.

Daily maintenance:

-Check the tank oil level frequently.

-Check the oil temperature;.

-Check the operation of each valve.

-Check oil leakage in pipes and cylinders.

First use the equipment, change the oil once a half year, and clean up the system every year。

2. Electrical system
Domestic and international famous brands are used in electrical systems. Some parts are easy to break down for frequent use.

The main failures are as follows:

Cause

Reason

Solutions

An action does not move.

The trip switch is not in place or damaged.

Intermediate relay damage

Electromagnetic valve relay damage.

Bad connection.

Adjust position replace

The temperature of the lead pot, nozzle is increased, or the temperature is slow.

Heating tube damage

Contactor damage

Damage of thermocouple

Replace

Temperature anomaly

Wrong type of thermocouple.

Thermocouple line reverse.

Failure of temperature controller.

Replacement of corresponding models.

Corrections.

Replacement of temperature controller.

Program does not run or program chaos

PLC fault

Maintenance or replacement
