4Common Problem

How to choose the right mould care products


1, the mold must be used after a long time grinding edge, grinding edge must be demagnetized, not with a magnetic, or easy to block material. Mold use companies to do a detailed record, statistics of its use, care (lubrication, cleaning, rust) and damage, which can be found which parts, components are damaged, the size of the wear to provide information to find and solve the problem, As well as the molding process parameters of the mold, the product used to shorten the mold test time, improve production efficiency. Should be in the injection molding machine, the normal operation of the mold, the test mold a variety of performance, and the final shape of the plastic parts measured by this information can determine the existing state of the mold to find the cavity, core, cooling system and Sub-surface and other damage, according to the information provided by plastic parts, you can determine the damage to the mold state and maintenance measures.
2, spring and other flexible parts in the course of the most vulnerable to damage the spring, usually the phenomenon of fracture and deformation. The way to take is to replace the spring in the replacement process must pay attention to the specifications and models, spring specifications and models through the color, diameter and length of the three to confirm that only in the three cases are the same circumstances can be replaced. Spring to import the quality is better, well-known brands such as Raymond mold spring.
3, the use of mold punch in the process prone to break, bending and eating bad phenomenon, punch sets are generally bite bad. Punch and punch the damage is generally the same specifications of the parts to be replaced. Punch the main parameters of the working part of the size, installation part of the size, length and size.
4, fasten the parts, check the fastening parts are loose, damage the phenomenon, the way is to find the same specifications of the parts to be replaced. <A i = 4> 5, parts such as nip pressure plate, preferably of plastic and the like, parts such as the discharge stripper plate, pneumatic ejector and the like. Check all parts of the relationship and when maintenance accessories for damage, repair the damaged part, pneumatic ejector check for air leaks, and specific measures taken. The trachea replace damaged. To focus on several important parts of the mold tracking detection: the role of the top part of the guide parts to ensure that the mold opening and closing movement and plastic parts of the top, if any part of the damage due to injury and stuck, will lead to shutdown, it should always keep Mold thimble, guide column lubrication (to choose the most suitable lubricant), and regularly check the thimble, guide column, etc. whether the deformation and surface damage, once discovered, to be replaced; complete a production cycle, the mold work surface , Movement, guide parts coated with professional anti-rust oil, in particular, should pay attention to with gears, rack mold bearing parts and spring mold elastic strength protection, to ensure that it is always in the best working condition; with the production time , The cooling channel easy to scale, corrosion, sludge and algae, so that the cooling channel cross-section smaller, narrow cooling channel, greatly reducing the coolant and mold heat exchange rate between the increase in production costs, so the flow of the clean-up attention should be paid; for hot runner mold, the maintenance of heating and control systems help prevent the occurrence of a production failure, and therefore especially To.
