We need to know about the maintenance of the deep drawing mould
In order to extend the service life of the mold and provide us with processing benefits to the greatest extent, the maintenance of the hardware mold products must be done well. The specific approach, we make a brief introduction for you.
First of all, the main tracking and testing of several important parts of the mold should be carried out: Ejection, guiding role is to ensure that the mold opening and closing movement and plastic ejection, if any parts of this jam due to injury, will be shut down, so should often maintain the mould thimble, guide post lubrication (should choose the most suitable lubricant), and check the thimble, guide pin, etc on time is the distortion and surface damage, once found, should be replaced immediately; After the realization of a production cycle, special antirust oil should be coated on the working surface, movement and guide parts of the mold. In particular, attention should be paid to the protection of the elastic strength of the bearing parts with gears and rack molds and the spring molds, so as to ensure that they are always in a better working condition. With the continuous production time, the cooling channel is easy to deposit scale, rust, silt and algae, so that the cooling channel section becomes smaller, the cooling channel becomes narrower, the heat exchange rate between the coolant and the mold is greatly reduced, and the production cost of enterprises is increased. Therefore, attention should be paid to the cleaning of the runner. For the hot runner mold, the maintenance of heating and control system helps to prevent the occurrence of production failures, so it is very important.
Therefore, after the end of each production cycle, the belt heater, rod heater, heating probe and thermocouple on the mold should be measured by ohmmeter. If there is any damage, it should be replaced immediately, and compared with the mold resume to make a good record, so as to facilitate the timely detection of problems and take countermeasures.
Secondly, we should pay attention to the surface maintenance of the mold, which directly affects the surface quality of the product, mainly to prevent rust. Therefore, it is very important to choose a suitable, high quality and special antirust oil. When the mold to achieve the production task, should be based on different injection molding to take different methods to carefully remove residual injection molding, copper rod, copper wire and special mold cleaning agent to remove residual injection molding and his sediment in the mold, then air dry. It is forbidden to clean hard objects such as wire and steel bar, so as not to scratch the surface. If there are rust points caused by corrosive injection molding, grinding machine should be used to polish, and coated with special antirust oil, and then the mold in dry, cool, dust-free storage.
Above are some of our suggestions and methods for mold maintenance. If you have other suggestions, welcome to discuss together.
