As long as the equipment has its service life, as long as we do regular maintenance, it can naturally extend its service life. Next, the editor will tell you how to effectively maintain injection molds.

1. The processing company should first equip each pair of molds with a resume card, record and count its usage, care (lubrication, cleaning, rust removal) and damage in detail. According to the card, it can find out which parts are damaged and worn. In order to provide information to find and solve problems, as well as mold forming process parameters, materials used in products, reduce mold trial run time and improve production efficiency.

2. The processing enterprise should test the various properties of the mold under the normal operation of the injection molding machine and the mold, and measure the size of the final molded part, and use this information to determine the current situation of the mold and find the cavity and core , The damage of the cooling system and the parting surface, the damage of the mold and the maintenance measures shall be judged according to the information provided by the plastic part.

3. Focus on tracking and testing several important parts of the mold: the ejector and the guide are to ensure the opening and closing movement of the mold and the ejection of the plastic parts. If any part of it gets stuck due to damage, it will cause downtime. Therefore, it is necessary to maintain the lubrication of the mold thimble and guide post (the most suitable lubricant should be selected), regularly check whether the surface of the thimble and guide post is deformed or damaged, and replace it in time if found;
