        Each injection mold shall be equipped with a resume card to record and count its use, maintenance (lubrication, cleaning, rust prevention) and damage in detail. On this basis, you can understand which parts have been damaged and the wear process. Provide information for finding and solving problems, as well as mold forming process parameters and product materials, so as to shorten the trial run time of the mold and improve production efficiency.
        Secondly, the processing enterprise should test the performance of the mold under the normal operation of the injection molding machine and the injection mold, and measure the size of the molded plastic parts. With this information, the current status of the mold can be determined. If there is a state, find out the damage of the cavity, core, cooling system and parting surface. According to the information provided by the plastic parts, you can judge the damage state and maintenance measures of the mold.
        It is necessary to focus on tracking and testing several important parts of the injection mold: the ejector and guide parts are used to ensure the opening and closing movement of the mold and the ejection of the plastic parts. If any part gets stuck due to damage, this causes production to stop. Therefore, the ejector pin and guide post of the die should be lubricated frequently (appropriate lubricant must be selected), and the ejector pin and guide post should be checked regularly for deformation and surface damage.
        Completion of replacement time - after a production cycle, professional anti rust oil shall be applied to the working surface, moving and guide parts of the die, and special attention shall be paid to the strong elastic protection of the bearing parts of the gear, rack die and spring die to ensure that they are always in working condition;
        With the continuous extension of production time, the cooling channel is easy to deposit scale, rust, sludge and algae, which reduces the cross section of the cooling channel and narrows the cooling channel, greatly reducing the heat exchange between the coolant and the coolant. Therefore, pay attention to the cleaning of the flow passage. For hot runner mold, the maintenance of heating and control system is helpful to prevent production failure, so it is particularly important. Therefore, after each production cycle, the strip heater, rod heater, heating probe and thermocouple on the die should be measured with an ohmmeter. In case of any damage, it shall be replaced in time.
        Jinan injection molding processing personnel think that if this is the case, compare it with the mold resume and make records, so as to find problems in time and take countermeasures. Only by keeping the injection mold in place can the service life of the mold not be damaged. Otherwise, no matter how good the mold is, it may be scrapped in advance.
        In addition, injection mold factories are often unable to complete mold processing at one time. A mold has to go through repeated trial production and modification stages, so trial production cost is a basic cost part of the mold. When calculating the trial mold cost, we should consider three aspects: labor, machine and rubber costs. For more information, you can visit our website at www.sdlqmj Com for consultation!
