In the use of injection mold
ing machine injection molding, injection molding machine factory we should how to do maintenance?
Next by our staff to introduce you to the maintenance of several steps.
1, processing enterprises should first give each pair of mould record card, detailed records, statistics of its use, care,
Lubrication, cleaning, rust)
And damage, which can be found on the basis of parts and components have been damaged, the wear degree of size, to find and solve the problem of information data, and the mould molding process parameters, the materials used for the product, so as to shorten the test time of mould, improve production efficiency.
2, processing enterprises should be in the injection molding machine, mold under normal operation, all kinds of mold test performance, and the final shape of parts size measured, through which information can determine the existing state of mould, find out the cavity, core, cooling system and parting surface damage, according to the information provided by the plastic, can judge the mold damage status and maintenance measures.
3, to track: focus on several important parts mould ejection, guiding role is to ensure that the mold opening and closing movement and plastic ejection, if any of these parts stuck due to injury, will lead to stop production, so often should keep the mould thimble, guide post lubrication (
To choose the most suitable lubricant)
And regularly check whether thimble, guide pin, etc the distortion and surface damage, once found, will change in time;
After completing a production cycle, do you want to work to the mold surface, sports, guide components coating professional rust-proof oil, especially should pay attention to with gear and bearing parts and spring rack mould stretch strength of protection, to ensure that it is always in the best working state;
With continuous production time, cooling way easy to deposit scale, rust, sludge and algae, decrease of cooling flow channel section, the cooling channel narrow, greatly reduce the cooling liquid and the mold, the heat transfer rate between the increase production costs.
We should pay attention to clean up of flow channel.
Hot runner mould expert luo hui said, heating and maintenance of the control system is helpful to prevent the occurrence of production failure, so is particularly important.
Therefore, each end of the production cycle in response to die band heater, rod heater, heating probe and thermocouple with ohmmeter measuring, if there are any damage, should change in time, and comparing with mould resume, recorded, in order to timely found the problem, the adoption of countermeasures.
4, should attach great importance to the surface of the mold maintenance, it directly influence the surface quality of the products, the key is to prevent the corrosion.
Injection molding machine factory think, choose a suitable anti-rust oil, high quality, professional becomes more and more important.
After the mold to complete production tasks, should according to different injection to take different approaches to remove residual injection carefully, available copper rod, copper wire and professional mold cleaner to remove residual injection and other sediments in the mould, and then dried.
Disable clear iron wire, steel and other hard objects, so as not to scratch the surface.
If corrosive injection caused by rust point, to use grinding machine grinding and polishing, and professional rust-proof oil spray, and then put the mould in a dry, cool storage, no dust.
Product top injection molding machine manufacturers has gained a lot of popularity over the recent past.
Our vision serves as the framework for our Product and guides every aspect of our business by describing what we need to accomplish in order to continue achieving sustainable, quality growth.
To do that, Hisson Plastic Machinery Co., Ltd. will need to make sure our business is listed accurately on as many directories as possible, including technology and quality.
