Maintenance of Injection Molding Chair Mould

Generally, due to the complexity and variety of products being produced, molds need to be frequently changed. After completing a production cycle for a product, the chair mould should be stored properly. However, some processing enterprises neglect the maintenance and care of the moulds, resulting in surface degradation and rust, which significantly affects product quality.

Unified Management of Injection Molding Chair Mould and Establishment of Documentation and Registration System

First, enterprises should create a corresponding history card for each chair mould and keep detailed records of its usage, including quantity statistics, usage status, maintenance condition, and any damages. When in use, relevant staff can refer to the history card to understand the condition of various parts, such as wear and damage of components. This enables accurate problem detection and early resolution, ensuring production quality of the chair mould, reducing trial run times, and improving product manufacturing efficiency.

Regular Testing of the Injection Molding Machine Performance for Chair Mould

During production, enterprises should regularly test the performance of injection molding machines. Additionally, measurements of the dimensions of molded plastic parts should be taken and documented in detail. By analyzing this information, enterprises can not only monitor the production status of the chair mould but also assess damages to parting surfaces, cooling systems, cores, and cavities. Based on the degree of wear or damage, effective maintenance measures can be applied to ensure normal production and improve overall efficiency.

Focused Tracking and Inspection of Key Components in the Chair Mould

First, during actual production, guiding and ejection components are critical for ensuring smooth part ejection and mold opening/closing movements. Any jamming or damage can halt the entire production line. Therefore, it is essential to regularly lubricate the mold guide posts and ejector pins, and inspect the ejector pins promptly. Any signs of damage or deformation must be addressed with immediate replacement.

Second, after each production cycle, anti-rust oil should be applied to the chair mould, especially on areas such as rack mould bearings, gears, and springs, to maintain their operational condition.

Third, after prolonged use, the cooling channels of the chair mould tend to accumulate algae, sediment, and rust. These deposits reduce the internal space of the cooling channels, significantly decreasing the heat exchange efficiency between the mold and cooling fluid, while also increasing production costs. Timely cleaning of these deposits is necessary to maintain product quality and production efficiency.

Fourth, when using hot runner molds, regular maintenance is essential, particularly for controlling the heating system. After completing a production cycle, the resistance of heating probes, rod heaters, and band heaters on the chair mould should be measured with an ohmmeter. If any components show damage, they must be replaced promptly and the details recorded thoroughly to provide effective solutions for future use.
