Many common items in our lives are made with plastic molds. A good plastic mold for small household appliances is very important for us to produce all kinds of small household appliances. Therefore, it is necessary to maintain plastic molds for small appliances. The following Yaosu introduces how to effectively maintain plastic molds for small appliances.
First of all, we need to make a maintenance list of plastic molds for small household appliances to record customer names, product materials, surface requirements, injection mold maintenance and damaged parts in detail, so as to achieve seamless handover, so as to avoid the replacement of special personnel or different responsible persons for manual handover Omission. Secondly, several important parts of plastic molds for small appliances were tracked and tested. The role of thimble and guide column is to ensure the opening and closing movement of the mold and the ejection of plastic parts. If any part of the mold is stuck due to damage, and a loaded product is stuck, the mold is closed again, and the damage of the mold will be greater. Therefore, the lubrication of the mold sleeve and the guide column should be maintained regularly, and the casing and the guide column should be regularly checked for deformation and surface damage. Once it is found that it should be replaced in time; afterwards, with the continuous extension of the production time, the cooling channel is prone to fouling, rust, sludge and algae, making the cooling channel cross section smaller and the cooling channel narrower, while the cooling channel greatly reduces the liquid and mold The heat exchange rate between the two increases the production cost of the enterprise, so attention should be paid to the cleaning of the runner; for the hot runner mold, the maintenance of the heating and control system is beneficial to prevent the occurrence of production failures. Make records and exchange text so that maintenance personnel can take countermeasures. The surface of plastic molds for small appliances should be treated with anti-rust, the most common is to apply anti-rust oil, so sometimes colored molds can be seen in injection molding manufacturers. This is because the surface of the injection mold has undergone professional anti-rust treatment. This is the most common method after mold repair, after injection molding is completed, the mold is lowered. It directly affects whether the product surface can meet customer requirements.
