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;

After completing a production cycle, professional anti-rust oil should be applied to the working surface, moving parts and guide parts of the mold, and special attention should be paid to the elastic strength protection of the mold load-bearing parts with gears, racks and springs to ensure that they are always In good working condition.

As the production time continues to prolong, it is easy to deposit scale, rust, sludge and algae in the cooling channel, which makes the cross section of the cooling channel smaller and the cooling channel narrower, which greatly reduces the heat exchange rate between the coolant and the mold, and increases Cost of production. Therefore, attention should be paid to the cleanliness of the cooling channels.

For hot runner molds, the maintenance of heating and control systems is very important because it helps prevent production failures. Therefore, after each production cycle, the strip heater, rod heater, heating probe and thermocouple on the mold must be measured with an ohmmeter. If it is damaged, it should be replaced in time, compared with the mold history, and make a record, so that the problem can be found in time and countermeasures can be taken.

4. The surface maintenance of injection molds should be paid attention to, which will directly affect the surface quality of the product, and it must be prevented from rusting. Therefore, it is particularly important to choose a very suitable, high-quality and professional anti-rust oil. After the mold design completes the production task, the residual injection molding should be carefully removed according to the design. If there are rust spots, grind and polish them and spray them with anti-rust oil.

The above is about the maintenance of the injection mold. If you need it, please contact us. Pay attention to our website and take you to know more about the consultation.
