How to maintenance of mold
Plastic processing industry people know that, except for injection molding, extrusion, blow molding machines and other host, plastics processing industry is still need to use a lot of auxiliary equipments. For the modern plastics industry, auxiliary equipment’s performance has great influence on product quality and production efficiency.
There is a wide variety of plastic auxiliary machinery, such as: metal separators, chillers, mold temperature controller, plastic crusher (shredders) and (desiccant) hopper dryer, etc. And each kind of plastic auxiliary machine has a number of classifications. Such as mould temperature controllers divided into oil type mould temperature controller and water type mold temperature controller. Plastic auxiliary equipment are essential equipment, Among them, plastic mold temperature controller which is a very important components.
At present, most of the mold temperature machine made in China is equipped with full digital PID temperature control and automatic control of cooling, can automatically maintain stability of mold temperature, the temperature can be accurately controlled within + / - 1 ℃,and have a number of security settings, The current domestic production of injection molding machine has basically adopts the plastic mold temperature controllers supporting the production.
Industrial auxiliary machinery, plastic mold temperature controller is imported from abroad, The main purpose of using mold temperature controller: First, the mold is heated to operate temperature, the second is to maintain a constant temperature in the operating temperature of the mold. If the above two points do succeed, can put the cycle time optimization, and ensure stable and high quality of injection molded parts. Mold temperature affects the surface quality, product flow, shrinkage, several injection molding cycle and deformation. Mould temperature is too high or inadequate for different materials will bring different effect.
Many manufacturers after buying mold temperature controller don’t pay attention to the later maintenance, so that the use of mold temperature controller isn’t very satisfied. Then, the plastic mold temperature controller maintenance, where should we to begin?
1, Buy a new plastic mold temperature, before using, please check whether the cooling water circulation, to prevent the cooling water because of insufficient to cause damage, We should keep the mold temperature machine working environment clean, to avoid the dust, this can greatly extend the mold temperature machine electrical components of the service life.
2, new plastic temperature, we want to make the maintenance of different measures according to the thermal media use. For the medium is water, we want to keep the water clean, so it is not easy to scale, also prevent pipe blockage. For the medium is oil, according to the using temperature, change regularly. For above 200 ℃, we periodically replaced every 1 or 2 months, and under 200 ℃, we will be able to change once a quarter, so it is good to avoid the temperature can’t rise up.
3.In the pipeline, we should according to the relationship between the pump and the pressure of the pipeline, to judge whether there is the phenomenon of clogging, if pressure is too small, we can put the heating tube removed and used to clean, especially the filter net system entrance hood, best month cleaning time.
4. Regularly check the water pump and oil pump for leaks, if necessary, the pump shaft seal can be replaced on a regular basis .
5. Electrical components, we can replace the life of components in a timely manner, regularly tested to ensure the safety.
The rapid development of the plastics industry to the mold temperature controller has brought great opportunities, but also great challenges. And similar to the developed countries such as Germany in terms of technology, experience or processing equipment, etc. relative to domestic levels all have a great advantage, of course, this is indicative of the level of domestic plastic mold temperature machine is still much room for improvement .
