Mold maintenance?

1: After the mold parts is used for a long time, the cutting edge must be sharpened, and the cutting edge surface must be demagnetized after grinding. The mold user company should make detailed records, count its use, care (lubrication, cleaning, rust prevention) and damage, based on which parts and components have been damaged, and the degree of wear, so as to provide information on discovering and solving problems. And the molding process parameters of the mold and the materials used in the product to shorten the trial run time of the mold and improve the production efficiency. The various properties of the mold should be tested under the normal operation of the injection molding machine and the mold, and the size of the final molded plastic part should be measured. The current state of the mold can be determined through this information, and the cavity, core, cooling system, and According to the information provided by the plastic part, the damage of the parting surface, etc., can be used to determine the damage state of the mold and the repair measures.
2: Springs and other elastic parts are most vulnerable to damage during use, and they usually appear to be broken and deformed. The method adopted is to replace. In the process of replacement, you must pay attention to the specification and model of the spring. The specification and model of the spring are confirmed by the three items of color, outer diameter and length. Replacement can only be done when the three items are the same. The quality of imported spring is better.
3: The punch is prone to breaking, bending and gnawing during the use of the mold, and the punch sleeve is generally gnawed. The damage of the punch and sleeve is generally replaced with parts of the same specification. The parameters of the punch mainly include the size of the working part, the size of the installation part, and the length dimension.
4: Fastening parts, check whether the fastening parts are loose or damaged, the method adopted is to find the parts of the same specification for replacement.
