The importance of maintenance of molds

In order to determine the damage status of the mold and maintenance measures. The processing enterprises should test the various properties of the mold, the mold, and measure the size of the final molded plastic parts, and the existing state of the mold can be determined, find the cavity, core, cooling. The system as well as the damage, etc.

At the same time, it is necessary to focus on several important components of the mold: top out, the role of the guide component is to ensure that the mold is opened and camped out, and if any of the parts are smashed, it will lead to production, so often Keep the needle thread, the lubrication of the guide post (to choose the most suitable lubricant), and check whether the thread, guide post, etc. is deformed and surface damage, once found, to be replaced in time;


After completing a production cycle, you should coat your professional anti-rust oil on the mold working surface, exercise, and guide components, especially to protect the strength of the elastic strength of the gear, the rack mold bearing portion and the spring mold to ensure it always In the best working condition;

As the production time continues, cooling decent sedimentary scale, rust, sludge and algae, etc., so that the cooling flow path is small, the cooling passage is narrowed, greatly reduces the heat exchange rate between the coolant and the mold, increasing the production cost of the company, Therefore, the cleaning of the flow path should be attached;

For thermal flow molds, the maintenance of heating and control systems facilitates preventing production failure, so it is particularly important. Therefore, each production cycle is completed, the belt heater, a rod heater, heating probe, and thermocouple, etc. are measured by the ohmmeter, if it is damaged, replace it in time, and performs with the mold history table. Comparison, make a record to find problems in a timely manner, take response measures.

The surface maintenance of the mold cannot be ignored, it directly affects the surface quality of the product, the focus is to prevent corrosion, so it is especially important to use a suitable, high quality, professional anti-rust oil. When the mold completes the production task, the residual injection molding should be carefully removed according to different injection molding, and the residual injection molding and other deposits of the mold can be removed by copper rod, copper wire and professional mold cleaning agent, and then air dry.

Disable wire, steel strip and other hard objects to clean, so as not to scratch the surface. If there is a rust point caused by corrosive injection, it is necessary to use a grinder to polish and spray the professional anti-rust oil, then place the mold in dry, cool, no dust.
