How to maintain the injection mould for producing plastic products
Injection mold is a tool for producing plastic products; It is also a tool to endow plastic products with complete structure and precise size. Injection molding is a processing method used in the mass production of some parts with complex shapes. Specifically, it refers to the injection of heated melted plastic into the mold cavity under high pressure by an injection molding machine, and the molded products are obtained after cooling and curing.

In daily production, the injection mold needs effective maintenance, which can increase the service life of the mold and reduce the production cost of the enterprise. How to effectively maintain the injection mold?

First of all, we should pay attention to the surface maintenance of the mold, that is, the appearance maintenance. The appearance of the mold should not be damaged, that is, it should not be corroded. At this time, it is particularly important to choose a suitable, high-quality, professional rust preventative oil. After the mold completes the production task, the residual injection molding should be carefully removed by different methods according to different injection molding. The residual injection molding and other deposits in the mold can be removed by using copper rods, copper wires and professional mold cleaning agents, and then air dried. It is prohibited to clean iron wire, steel bar and other hard parts to avoid scratching the surface. If there are rust spots caused by corrosive injection molding, use a grinder to grind and polish, spray professional rust preventative oil, and then store the mold in a dry, cool, dust-free place.

Secondly, the injection mold should be cleaned regularly to ensure the hygiene of the mold. For product production, the products produced by the clean and sanitary mold are better, and this will not pollute the mold.

Thirdly, check the parts of the mold to see if there is any fault in the mold. The ejecting and guiding parts are used to ensure the opening and closing movement of the mold and the ejecting of the plastic parts. If any part of the mold gets stuck due to damage, production will be stopped. Therefore, keep the lubrication of the mold thimble and guide post (the most appropriate lubricant should be selected), and regularly check whether the thimble and guide post are deformed and damaged on the surface. Once found, they should be replaced in a timely manner; This avoids the impact on product production caused by mold failure.

Injection molding is a widely used method for producing plastic products. To ensure the efficient and effective operation of an injection mold, regular maintenance is necessary. Proper maintenance can not only improve the longevity of the mold but also ensure high-quality production. Here are some tips on how to maintain an injection mold:

  1. Clean the mold regularly: After each use, clean the mold with a soft cloth and use a cleaning solution to remove any dirt or debris. This will prevent contamination of the mold and ensure that the mold is ready for the next production run.
  2. Inspect the mold for wear and tear: Regular inspection of the mold can help identify any issues that may cause defects in the plastic products. Check for any cracks, deformations, or excessive wear on the mold surface.
  3. Lubricate the mold: Proper lubrication can reduce wear on the mold and improve its lifespan. Use a high-quality lubricant that is specifically designed for injection molds. Apply the lubricant to the mold's moving parts and ensure that it is evenly distributed.
  4. Check the temperature control system: The temperature control system is critical to the operation of the injection mold. Regularly check the system to ensure that the mold is operating at the correct temperature. Replace any damaged or worn-out components as needed.
  5. Store the mold properly: When not in use, store the mold in a clean and dry location. Avoid exposing the mold to direct sunlight or extreme temperatures, which can cause deformation or other damage.

By following these simple tips, you can ensure that your injection mold is maintained properly and that it produces high-quality plastic products consistently. Regular maintenance can also reduce the risk of mold failure, which can be costly in terms of both time and money.
