Dongguan mold temperature machine is widely used in plastic molding, light guide plate, die casting, extrusion, extrusion, rubber tires, rollers, chemical industry, reaction kettle, adhesion, mixing, and other industries. In a broad sense, it should be called a mold temperature machine, which includes two aspects of temperature control: heating and freezing. Dongguan mold warming machine is widely used in the plastic industry.
1. Before using the new Dongguan mold warmer, it is necessary to check whether the mold pipes are connected and whether the cooling water flows to prevent damage to the mold warmer. We should keep the working environment of the mold heater clean and avoid dust, which can greatly extend the service life of the electrical components of the mold heater.
2. For the new Dongguan mold heater, we need to take different maintenance measures based on the heat transfer media used. If the medium is water, we should keep the cooling water source clean, so that it is not easy to scale and block the pipeline. If the medium is oil, we need to regularly replace it according to the operating temperature. If the temperature is above 200 ℃, we need to regularly replace the Dongguan mold temperature machine once every two to three months, while if the temperature is below 200 ℃, we can replace it once every six months or so, which effectively avoids the problem of temperature rise.
3. In terms of pipelines, we need to determine whether there is any blockage in the pipeline based on the relationship between the pump and pressure. If the pressure is too low, we can take out the flange plate containing the heating pipe and clean the oil barrel, especially the filter screen cover at the system inlet, preferably once a month.
Regularly inspect the water pump and oil pump of the mold temperature machine for water and oil leakage. If necessary, the pump shaft seal can also be replaced regularly.
Precautions for die casting mold warming During the operation of die casting mold warming, precautions should be taken:
Principles for selecting the working temperature of the die casting mold temperature machine:
1) The mold temperature is too low, the internal structure of the casting is loose, and it is difficult to discharge air, making it difficult to form.
2) The mold temperature is too high and the internal structure of the casting is dense, but the casting is easy to "weld" into the mold cavity, and it is difficult to remove the casting due to mold adhesion. At the same time, excessive temperature will cause mold expansion, affecting the dimensional accuracy of the casting.
3) The mold temperature should be selected within a suitable range. Generally, after testing, constant temperature control is preferred.
The following points should be noted in die casting production:
1) Material melting temperature Mold temperature and solution temperature during injection;
2) The determination of injection pressure, mold locking force, mold opening force, and the required injection ratio, injection speed, etc. according to the condition of the workpiece;
3) It is necessary to recuperate the condition of the die cast product to obtain a perfect product;
Precautions for temperature transfer of die casting mold:
What should be paid attention to when transferring a die casting mold from a die casting mold temperature machine?
1. Check whether the mold appearance is intact
2. Whether the mold core and insert have defects such as defects, cracks, bumps, etc
Whether the supporting accessories are complete
3. Whether the mold action is normal (it may be a bit difficult, but it can't be seen without being on the computer)
5. Whether relevant mold drawings are complete
6. Repair and maintenance records of molds (estimated to be difficult)
