Cleansing of frame and mold parts currently consumes a disproportionately large amount of time compared to all other maintenance operations (disassembly, commissioning, and assembly). On the one hand, it is essential for improving the reliability of molds and ensuring the quality of the finished product. The majority of molds, on the other hand, are cleaned by hand. In this article, we will discuss die casting mold cleaning, and we will outline the specific steps to take when cleaning a die casting mold in detail.

Die Casting Mould Cleaning Culture
Mold cleaning is not only an important process in mold maintenance, but it is also a bottleneck that prevents mold maintenance from being completed effectively. a portion ofMold development and manufacturing are much more time-efficient than mold cleaning. As soon as the mold is cleaned, it can be prepared for the next production run, resulting in a relatively short amount of time spent on mold cleaning. According to the findings of the factory investigation, the corridors in the factory and the molds configured in the workplace essentially occupy the limited working space available in the workplace, which is a problem.

The mold is readjusted immediately after the completion of the production without the need for a cleaning process, and the mold is then used for regeneration again and again. It is unlikely that the operation of the mold will be affected if the plastic parts that have been manufactured are clean. If residues accumulated in the mold have an adverse effect on the quality of parts or if the mold is worn, the mold must be cleaned, and only the cleaning process needs to be performed at that point.

To clean molds and stainless steel, some factories primarily employ interns in machinists or mold factories, and then the molds and stainless steel are divided by service technicians, according to their needs. The tracking marks, on the other hand, will be removed from the molds and templates after they have been thoroughly cleaned. It is difficult for maintenance technicians to locate defects in molds and parts and to repair them in a timely and effective manner.

In reality, mold cleaning does not necessitate the talents of senior mold making technicians; however, newcomers who are unfamiliar with the special functions and disadvantages of the mold, or who are unfamiliar with the mold's characteristics in the critical sealing field, will have no responsibility for mold cleaning at all when they first arrive. Please make a decision. Mold cleaning operations are distributed in an inefficient manner, resulting in the continuous production of molds that have performance defects. Furthermore, it will rise significantly as a result of the increase in joints, burrs, corners, early electroplating or steel movement, and the mixing of materials in the mold. The problem of mold budget is frequently caused by the conservative culture of "temporary fire extinguishing," which will never monitor or explain defects, let alone find the root cause of the problem, as is the case in many industries.

Cleaning Procedures That Are Standardized
In order to maintain consistency, mold maintenance requirements and maintenance operations must be consistent in their execution. If the goal of "low cost to effect" is to be achieved, mold cleaning must be done with care and precision. Mold cleaning procedures should be developed in detail. Similarly, when different parts of the mold are cleaned using different cleaning methods, such as stamping internal cleaning, edge wiping, general cleaning, and main cleaning, the cleaning operation methods used vary as well.

Visual inspection of coating wear, track marks, and mold residue content in the ventilated and non-ventilated fields can be used to determine the sequence and frequency of mold cleaning after a certain period of mold operation and after visual inspection of coating wear, track marks, and mold residue content in the ventilated and non-ventilated fields. Because of this, it is critical to understand the mold's safe operation cycle and to document the results of observations of residual residue and wear in the mold during its operation.

All molds must be equipped with records of relevant maintenance steps and intervals, which are specific to the operation cycle of the molds in question. Controlling the internal grease level, as well as the gear broach, sliding block, internal shaft pin and bushing, and other movable parts, is the key to ensuring stable production, according to general principles. Aside from pollution and obstruction of water pipelines and sprinklers, other major factors affecting production include leakage of manifolds, rust and corrosion caused by water leakage and condensation, among other things.

What Level of Clean is Enough?
Most of the time, after the molding process is completed, dirt or residues are left on the mold surface as a result. The final cleaning conditions vary depending on the type of residue that has been removed. PVC and other resins release hydrogen chloride gas, which has the potential to corrode a wide range of mold steels. In addition to flame retardants and antioxidants, which may cause corrosion to steel, other residues are separated from each other. It is also possible that the rusty steel's pigment colorant is difficult to remove because of the rust. Even ordinary sealing water, if left on an untreated mold surface for an extended period of time, will cause damage to the mold.
As a result, the mold must be cleaned as frequently as necessary in accordance with the established manufacturing cycle. It is necessary to open the mold vent hole every time the mold is removed from the press in order to remove all oxidizing dirt and rust from the mold as well as the unimportant part of stainless steel, in order to avoid the slow corrosion of the steel surface and edge. In the majority of cases, even after cleaning, rust will appear immediately on the surface of the mold that is susceptible to rusting in the absence of a protective coat. As a result, even if it takes a long time to grind the unprotected mold, the rust on the surface of the mold cannot be avoided completely.
