In the modern manufacturing industry, die casting technology is widely used in various industries with its efficient and accurate characteristics. As the core equipment of die casting production, the stable operation and efficient production of die casting machine cannot be separated from the collaborative work of various accessories. However, these parts in the long-term use of the process, will be affected by wear, corrosion and other factors, resulting in performance decline, and even affect the entire production process. Therefore, it is particularly important to carry out regular maintenance and maintenance of die casting machine accessories. Let’s discuss the maintenance points of die casting machine parts.

1、 Overview of die casting machine accessories

Die casting machine accessories variety, including mechanical accessories, heating devices, consumables and so on. These accessories each play an important role in the die casting process, such as the nozzle for shooting the metal solution into the mold, the punch for pushing the metal solution, and the heating sleeve and heating cake to ensure that the metal solution is maintained at the appropriate temperature. Because these parts work in the harsh environment of high temperature, high pressure and high speed, they are vulnerable to wear and corrosion and require regular maintenance and maintenance.

2、 The importance of die casting machine parts maintenance

Improve production efficiency: Regular maintenance can ensure that the parts of the die casting machine are in good working condition, reduce the downtime caused by parts failure, thereby improving production efficiency.

Extend service life: Through reasonable maintenance, you can slow down the wear rate of parts, extend their service life, and reduce the operating costs of enterprises.

Ensure product quality: the good condition of the parts is essential to ensure the quality of the die casting parts. Regular maintenance can reduce product quality problems caused by parts problems.

Improve safety: The die casting machine works at high temperature and high pressure, and there are security risks. Regular maintenance can detect and solve potential safety problems in time to ensure the personal safety of employees.

3、 Die casting machine parts maintenance points

3.1、 Maintenance of mechanical parts

Nozzle and mold contact surface: After each die casting is completed, lubricating oil is applied to the nozzle and mold contact surface to lubricate to prevent wear caused by long-term use. At the same time, the injection hole of the nozzle should be regularly checked whether it is blocked by aluminum slag or other impurities, and cleaned up.

Spoon, hand-held tools, etc. : These tools are easy to adhere to the metal solution during use, and should be cleaned more than once a day to prevent the metal solution from being difficult to remove after solidification.

Key parts such as punches and models: these parts play a key role in the production process and should be cleaned every six months. When cleaning, you can choose to use a special cleaning solution or diluted sulfuric acid to remove surface attachments and oxide.

3.2、 Maintenance of heating device

Heating sleeve and heating cake: After the use of these heating devices for a long time, the surface will form a layer of oxide, affecting the heating effect. Therefore, the oxide should be cleaned once a week. When cleaning, you can use paraffin or diesel oil to heat to a certain temperature, and brush to remove the oxide skin.

Heating element: For electric heating element, it should be checked regularly whether its resistance value is normal, and whether there is short circuit or open circuit phenomenon. If there is any problem, it should be replaced or repaired in time.

3.3、 Replacement and supplement of consumables

Release agent (release agent) : In the die casting process, release agent plays a role in lubricating, protecting the mold and reducing friction. The stock of release agent should be checked regularly and replenished in time. At the same time, it is necessary to ensure that the quality of the release agent meets the requirements and avoid the use of inferior products leading to mold damage or product quality problems.

Plunger oil (pellet oil) and hydraulic oil: These oils lubricate and cool the die casting machine during operation. The oil level and oil quality should be checked regularly, and if the oil level is found to be too low or the oil quality is poor, it should be replaced or added in time.

3.4、 Other precautions

Keep the environment clean: The environment of the die casting workshop has a great impact on the life of the parts. The workshop should be kept clean and dry to avoid dust and moisture causing corrosion to parts.

Regular training of employees: Conduct regular training for employees to improve their operating skills and maintenance awareness. Make employees aware of the importance of accessories and how to use and care for them properly.

Establish maintenance system: develop a detailed maintenance plan and record form, and clarify the maintenance cycle and method of each part. At the same time, it is necessary to track and record the maintenance situation in order to find problems in time and take measures to solve them.

4、Case study: the practical effect of die casting machine parts maintenance

A die-casting enterprise has achieved remarkable results after implementing a comprehensive parts maintenance plan. First of all, production efficiency has been significantly improved. Because the parts are in good working condition, the downtime caused by failure is reduced. Secondly, the service life of the accessories has been extended. Through reasonable maintenance, the wear rate is slowed down and the operating cost of the enterprise is reduced. Finally, the quality of the product is also improved. Due to the good condition of the parts, the stability and accuracy of the die casting process are ensured, thus reducing the incidence of product quality problems.

5、Conclusion

The maintenance of die casting machine parts is the key to improve production efficiency and extend service life. Regular care and maintenance can ensure that parts are in good working condition to reduce downtime due to failure and improve product quality. At the same time, reasonable maintenance can also slow down the wear rate of parts and reduce the operating costs of enterprises. Therefore, enterprises should pay attention to the maintenance of die casting machine parts, formulate detailed maintenance plans and strictly implement them to ensure the smooth progress of production and the sustainable development of enterprises.
