Drip die is a common injection mold, used in the production of drip irrigation belt, plastic bottle caps and other products. In the process of processing these products with the drip die, some problems sometimes occur. This paper will introduce some methods to solve the problem of drip die processing.
First, turn the mold
After long-term use, due to the wear and impact of molten plastic and other factors, the surface of the drip mold is easy to form notch, wire hanging, burning and other defects, resulting in the quality of injection molding decline. At this time, it is necessary to turn the mold, that is, to repair and maintain the mold. Turning die can be achieved by grinding, polishing, welding, machining and other methods.
Two, reasonable design
In the process of producing drip die, we should pay attention to the rational design of die. Reasonable design can make the mold in the process of processing more stable, reduce the probability of problems.
(1) Design a reasonable cooling system. The cooling system of the dropper mold should be properly arranged and the pipeline planning appropriate to ensure that the injection process of the plastic material will not be affected by the high temperature of the mold.
(2) Design a reasonable exhaust system. The exhaust system of the drip die should be arranged reasonably and have a smooth channel to ensure that no problems will occur during the injection process because the gas cannot be discharged smoothly.

Third, strengthen maintenance
Timely maintenance of drip die is also an important means to prevent problems.
(1) Regular cleaning. Clean the drip mold according to the specified time to ensure that impurities, dust, etc., will not affect the quality of injection molding.
(2) lubrication maintenance. The various moving parts of the drip die can be coated with lubricating oil, which can effectively reduce friction, reduce wear and improve service life.
Four, replace the material
If there is a problem with the drip mold and it cannot be fixed, you can consider changing the material. The selection of high quality materials can enhance the wear resistance and loss resistance of the drip die and extend the service life.
Five, standard operation
Attention should be paid to standardized operation when using the drip die. The operation is not standard, may lead to mold damage, or injection product quality problems. Therefore, when using the drip die, the operation should be standardized management, and the workers' non-standard operation should be corrected in time.
In a word, there are various problems in the use of the drip die. However, as long as we carefully analyze and solve the problem, we can ensure the production of high quality drip molds and injection products.
