How to effectively maintain the injection mold
发布日期: 2019.09.23 Back to list source: Release date: 2019.09.23

How to perform effective maintenance of injection molds? Generally speaking, it is not possible to let the mold rust. If rust is found, use a grinder to grind and polish. If the cooling channel has accumulated water and dirt, the flow channel needs to be cleaned. If the dirt is difficult to remove, please use copper rods, copper wires and professional mold cleaning agents to remove the dirt in the mold, or the residual injection molding and other residues. Maintenance is not a matter of overnight, it is a matter that must be standardized implementation.

First of all, the company should equip each pair of molds with a resume card to record and count their use, care and damage in detail. According to these materials, we can find out which parts and components have been damaged and the degree of wear and tear, in order to provide information and information to find and solve the problem, as well as the molding process parameters of the mold, the materials used in the product, in order to shorten the mold test time and improve production efficiency.

Generally speaking, as the production time continues, the cooling channel is prone to deposit scale, rust, silt and algae, etc., which makes the cross section of the cooling channel smaller and the cooling channel narrower, which greatly reduces the heat exchange rate between the cooling liquid and the mold and further increases Enterprise production costs, therefore, attention should be paid to the cleaning of the flow channel. This is especially important for businesses. For hot runner molds, the maintenance of the heating and control system is very important to prevent production failures.

In this way, after the end of each production cycle, the belt heater, rod heater, heating probe and thermocouple on the mold should be measured with an ohmmeter. If it is found that the damage is found, it should be replaced in time, and compared with the mold resume, and records should be made so that problems can be found in time and countermeasures should be taken. It would be best if no problems were found.

Injection molding is a very precise thing. So the maintenance work is more delicate. The above also explained how to solve problems such as mold rust. How to avoid the accumulation of dirt and narrow the cooling channel. Maintenance of heaters after production. Only when the injection mold has been effectively maintained can it be used for a longer period of time.
