Maintenance of Mould
Oct 24, 2017

1.The mold must be worn after a long period of time, after grinding the edge must be demagnetization, can not be magnetic, or prone to plugging material. Mold Use enterprises to do detailed records, statistics its use, care (lubrication, cleaning, rust prevention) and damage, according to which parts, components have been damaged, the degree of wear and tear to provide information to find and solve the problem, as well as the mold molding process parameters, products used in order to shorten the commissioning time of the mold, Improve production efficiency. Should be in the injection molding machine, the normal operation of the mold, testing the various performance of the mold, and the final molded plastic parts size measurement, through this information to determine the existing state of the mold, to find the cavity, core, cooling system and the breakdown of the fractal surface, according to the information provided by the plastic parts, you can determine the mold damage status and maintenance measures.

2.Spring and other elastic parts in the use of the most easily damaged springs, usually the occurrence of fracture and deformation phenomenon. The method is to replace, in the replacement process must pay attention to the spring specifications and models, the spring specifications and models by color, diameter and length of three items to confirm, only in three items are the same case can be replaced. The spring is good for the quality of the imported.

3.The use of the mold in the process of punching head prone to break, bending and gnawing bad phenomenon, the punching sleeve is generally gnawing bad. The damage of punching head and punching sleeve is usually replaced with the same specification. The main parameters of punching head are working part size, installation part size, length size and so on.

4.Fastening parts, check fastening parts are loose, damage phenomenon, the method is to find the same specifications for replacement parts.

5.Pressure material parts such as pressure plate, excellent glue, unloading parts such as stripping plate, pneumatic top material and so on. Check the parts in the maintenance of the relationship and the damage, the damaged part of the repair, pneumatic top material inspection has no leakage phenomenon, and the specific situation to take measures. Replace if the trachea is damaged. To focus on several important parts of the mold tracking detection: The role of the ejection and guide parts is to ensure the mold opening and closing movement and plastic parts top out, if any part of the damage caused by the card, will lead to discontinued, it should always keep the mold thimble, guide column lubrication (to choose the most suitable lubricant), and regularly check the thimble, Whether deformation and surface damage occurred in the Guide column, once found, to be replaced in a timely manner, after completion of a production cycle, the mold work surface, movement, guide parts coated professional anti-rust oil, especially on the gear, rack die bearing parts and spring mold elastic strength protection to ensure that it is always in the best working condition ; As the production time continues, the cooling channel is easy to deposit scale, rust, silt and algae, so that the section of the cooling runner becomes smaller, the cooling passage narrows, the heat exchange rate between the coolant and the mould is reduced greatly, and the production cost is increased, so the cleaning of the convection channel should be paid attention to; for hot runner die The maintenance of heating and control system is very important to prevent the occurrence of production failure.
