The cutting edge of the mold must be sharpened after long time use, and the cutting edge surface must be demagnetized after grinding, and it cannot be magnetized, otherwise it is easy to cause blockage. The mold user company must make detailed records, count its use, care (lubrication, cleaning, rust prevention) and damage, based on which parts, components have been damaged, and the degree of wear, so as to provide information on finding 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. Plastic furniture mould 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 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 distribution According to the information provided by the plastic parts, the damage status of the mold and the repair measures can be judged for the damage of the molding surface.
Springs and other elastic parts are easy to be damaged during use, and usually break and deform. The method adopted is to replace. During the replacement process, we 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. Only when the three items are the same can they be replaced. The quality of imported spring is better.
The punch is prone to breaking, bending and gnawing during the use of the mold, and the punch sleeve is generally broken. The damage of the punch and the punch sleeve are 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. .
Fasten the parts and check whether the fastening parts are loose or damaged. The method adopted is to replace the parts with the same specifications.
