- Focus on tracking and testing several important parts of the Plastic Injection Parts mold: Ejection and guide parts are used to ensure the opening and closing movement of the plastic injection part mold and ejection of the plastic part. If any part of the plastic injection part mold is stuck due to damage, it will lead to shutdown. Therefore, lubrication of the ejector pin and guide pillar of the plastic injection part mold should be kept regularly (the most suitable lubricant should be selected), and whether the ejector pin and guide pillar are deformed or damaged on the surface should be checked regularly. Once found, they should be replaced in time. After completing a production cycle, professional antirust oil should be applied to the working surface, movement and guide parts of the plastic injection part mold, and special attention should be paid to the protection of the elastic strength of the bearing parts of the plastic injection part mold with gears and racks and the spring plastic injection part mold to ensure that it is always in the best working state. With the continuous production time, the cooling channel is easy to deposit scale, rust, sludge, algae, etc., making the cross section of the cooling channel smaller and the cooling channel narrower, greatly reducing the heat exchange rate between the cooling liquid and the mold of the plastic injection part and increasing the production cost of the enterprise. Therefore, attention should be paid to the cleaning of the cooling channel. For hot runner plastic injection mold, the maintenance of heating and control system is helpful to prevent the occurrence of production failure, so it is especially important. Therefore, after the end of each production cycle, the belt heater, rod heater, heating probe, thermocouple, etc. on the plastic injection part mold should be measured with ohmmeter. If there is any damage, it should be replaced in time, compared with the resume of the plastic injection part mold, and recorded so as to find the problem in time and take corresponding measures.
- After the plastic injection part mold completes the production task, different methods should be adopted to carefully remove residual injection according to different injection molding. Copper rods, copper wires and professional plastic injection part mold cleaning agents can be used to remove residual injection and other deposits in the plastic injection part mold, and then air-dry. It is forbidden to clean hard objects such as iron wires and steel bars to avoid scratching the surface. If the Optical Cable Connector Boxhas rust spots caused by corrosive injection molding, it shall be ground and polished with a grinder and sprayed with professional antirust oil, and then the plastic injection part mold shall be stored in a dry, cool and dust-free place.
