How should precision injection molds be cleaned?

Many people will have this kind of doubt, the surface of high precision injection molding mold will be polluted by the environment in the production process, especially before the production of transparent products, it is necessary to clean the surface of the mold and prevent small black spots on the product. So how should we clean the injection molding mold?

1. Manual cleaning

Manual cleaning can also be called pure manual cleaning, is a traditional way of cleaning, can remove some simple stains. But this kind of cleaning method has more shortcomings, such as increased labor cost, low labor efficiency in the work, such as dead corner, blind hole, fine hole, sun lines can not be cleaned in place, cleaning staff do not pay attention to also easily damage the mold surface.

2. Dry ice cleaning

Dry ice cleaning, also known as cold spray, is the use of compressed air to push a substance, so that the medium impact on the surface, and then clean the surface or the surface of the solution. To be cleaned on the surface of the object stains, oil stains, residual residue and other rapid freezing, and then solidification, embrittlement, be removed, and at the same time with the air flow elimination. Dry ice cleaning is suitable for cleaning large planar molds such as foam molds. Dry ice belongs to consumption is easy to volatilize, storage is inconvenient, cleaning noise; Be sure to wear protective masks, protective masks, myopic glasses and other safety protection tools when cleaning.

3. Ultrasonic cleaning

Ultrasonic cleaning adopts chemical and physical processes to carry out cleaning, and the whole process of processing can be accurately adjusted according to the daily cleaning tasks. Cleaning is easy to use, no manual participation in the work. The mold is immersed in a cleaning liquid tank equipped with ultrasonic vibrators. Ultrasonic cleaning effect is based on the basic principle of cavitation erosion, namely, the replacement effect of pressure and suction. Bubbles will be caused in the suction link, and bubbles will burst in the charging link, which will cause obvious flow fluid and flow field, and "destroy" dirt from the mold.

4. Electrolytic cleaning

Electrolytic cleaning according to electrolysis and ultrasonic fusion, can thoroughly clean the mold, completely clean the mold surface gas qi, sulfide, carbon, oil, rust, etc., mold core stains. Not easy to damage the mold itself, including edges, bite marks, coating, etc. The advantage is to save labor, improve the high efficiency of mold maintenance, reduce the unqualified rate, less noise cleaning, easy to use, after cleaning must do anti-corrosion.
