One pair of zinc alloy die-casting molds is composed of a wide variety of mold components when fully assembled.Runners, ejector pins, and other components are included in these parts.At the majority of domestic mold manufacturers, the finishing stage of production typically entails the application of the processes of grinding, electric machining, and fitter processing.At this stage in the production process, it is necessary to exercise control over a wide variety of technical parameters, including shape tolerance, internal stress, part deformation, and dimensional accuracy.It possesses a certain degree of plasticity, and it is possible to achieve good processing results by exercising proper control over the processing.
Based on the outward appearance and the shape of the parts themselves, shafts, plates, and special-shaped parts can be roughly divided into these three categories: shafts, plates, and special-shaped parts.It is necessary to exercise control over the internal stress of die-casting mold parts before they are subjected to the heat treatment process. This is done in order to ensure that the dimensional stability of the parts is preserved throughout the processing phase.This is the case regardless of whether or not the components are capable of reaching the specified level of hardness.The material that is being processed can have a significant impact on the treatment procedures that are used.For certain convex and concave molds that are subjected to high work intensity and severe stress, an innovative material known as powder alloy steel can be used.After being quenched, the workpiece maintains a significant amount of stress, which leaves it vulnerable to cracking during the finishing or subsequent processing stages.Tempering the parts while they are still hot after they have been quenched is the best way to eliminate the quenching stress that may have been introduced.After having its temperature controlled to be between 900 and 1020 degrees Celsius during the quenching process, the material is then lowered to between 200 and 220 degrees Celsius, cooled with air, and then rapidly returned to the furnace for tempering at a temperature of 220 degrees Celsius.Molds in which the failure mode is the primary cause of the issue are preferable to use in the context of.Before finishing, the stress must be completely released; this can be accomplished through stress relief annealing, multiple aging treatments, or both stress relief annealing and multiple aging treatments.Because powder alloy steel parts are able to withstand high temperature tempering, a secondary hardening process can be utilized on these parts after they have been quenched.This process begins with quenching at 1050-1080 degrees Celsius, and then continues with tempering at 490–520 degrees Celsius for a number of times.This can obtain higher impact toughness and stability, and it is very suitable for molds with chipping as the primary mode of failure as it is very suitable for molds with chipping as the primary mode of failure.

The fabrication of the electrodes is the initial stage of the EDM process. Depending on the task at hand, the electrodes can have a coarse or fine grain size. When it comes to the material that is used for electrodes in the context of general steel processing, copper electrodes are the most common choice that is available to choose from. Because of this, once the processing has been completed, the fitter needs to strengthen and polish the surface of the parts in order to remove any hidden dangers that may have been introduced during the processing. On the surface that has been electro-machined, there will typically be produced a metamorphic hardened layer with a thickness ranging from about 6-10 micrometers. This layer will be produced on the surface. The layer that underwent the hardening process is brittle and retains some of its original stress. The method that is used in this situation involves polishing the surface and removing the layer that is brittle.
During the grinding and electrical machining processes, the workpiece will be magnetized, albeit only to a limited degree. In addition to this, the piece of work will have a very weak magnetic force; as a result, it will be very simple to attract some smaller things to itself. After the installation of the guide post and the guide sleeve, the mold will typically be the next component to get its place in the assembly line. The frame, the punch, and the die, and then make any necessary adjustments to the gaps, paying particular attention to the space between the punch and the die. Afterwards, the frame, the punch, and the die. In order to find solutions to the issues that have been identified, one tactic that can be utilized is referred to as "reverse thinking. "This strategy entails working backwards through the steps of the process, moving from finishing to roughing, and checking each step in turn until the root of the issue is identified and the problem is resolved. Working backwards through the steps of the process involves moving from finishing to roughing.
When carrying out fine grinding, it is of the utmost importance to select the appropriate grinding wheel. When working with materials that have a high quenching hardness, organic bonding is preferred over inorganic bonding. This applies to the processing of cemented carbide as well as other materials. In recent years, thanks to the utilization of new materials, the CBN grinding wheel, which is also known as the cubic boron nitride grinding wheel, has proven to be effective. Very good processing effect; the effect achieved is superior to that achieved by other types of grinding wheels when used for finishing on CNC forming grinders, jig grinders, and CNC internal and external cylindrical grinders. The effect achieved is also superior die casting aluminum to that achieved by conventional grinding wheels. However, the long and thin thin plate part that is frequently encountered in processing is notoriously difficult to process, and the surface grinder is responsible for the majority of the processing of plate parts. However, the parallelism does not fulfill the requirements, despite the fact that the measurement of the thickness is accurate.
It is possible to improve the grinding effect and satisfy the requirements of parallelism because the feed rate of the tool during processing is kept to a minimum. Additionally, the surface of the knife has multiple smooth areas. During the time that the processing is taking place, the head frame and the top have the same functional characteristics as the bus bar. In the event that there is a problem with runout, the problem will be present in the processed workpiece as well, which will have an effect on the quality of the part. Before beginning to grind the inner hole, the coolant should first be completely poured to the grinding contact position. This will ensure that the grinding process die casting manufacturer will proceed smoothly and won't cause any hiccups. It is recommended that a clamping process table be utilized when working with thin-walled shaft parts; however, the clamping force applied to the table should not be excessive. If this is the case, it won't be hard to create an inner triangle deformation on the workpiece's circumference, which will result in additional labor being needed.
