How can injection molding molds from manufacturers be maintained more effectively
1. The processing enterprise first needs to provide a resume card for each mold, detailing and statistically analyzing its application, medical care (wetting, cleaning, rust prevention treatment), and damage status. Therefore, it can be seen which components and parts have been damaged, and the horizontal size of the damage to ensure the detection and resolution of problem information materials, as well as the main parameters of the plastic box injection mold molding process and commonly used raw materials for the product, to reduce the trial run time of the mold, Improve product quality.
2. Processing enterprises should test various characteristics of molds under the premise of normal operation of plastic machines and molds, and detect the size of the plastic parts formed after Z. Based on this information, the current situation of the mold can be determined, and the damage to the concave mold, core, refrigeration system, and its parting surface can be found. Based on the information provided by the plastic parts, the damage to the mold and its maintenance measures can be identified.
3. Key tracking and testing will be carried out on many key components of injection molding plastic: the ejection and guiding components are used to ensure the opening and closing movement of the mold and the ejection of the plastic part. If all of these parts are stuck due to injury, it will cause shutdown. Therefore, it is necessary to regularly maintain the lubrication of the mold's top pin and positioning pin (using appropriate lubricants), and regularly maintain the mold's top pin, positioning pin, and other components to ensure deformation and surface damage. Once discovered, Timely dismantling and replacement; After a production cycle, professional rust inhibitors will be applied to the surface, movement, and guiding components of the mold during operation. Special attention should be paid to the maintenance of the elastic compressive strength of the parts containing transmission gears, worm mold rolling bearings, and torsion spring molds to ensure that they are in good operating condition from beginning to end; With the continuous production time, the cooling channel is prone to accumulation of dirt, rust, sludge, and water plants, which reduces the cross-sectional area of the cooling passage, reduces the cooling safety channel, significantly reduces the heat exchange rate between the refrigerant and the car mold, and increases the company's product cost. Therefore, the removal of heat from the flow channel should be taken seriously; For hot runner system molds, the maintenance and upkeep of heating and automatic control systems are beneficial in avoiding common manufacturing failures, and therefore are crucial. Therefore, after each production cycle is completed, the continuous electric heater, rod shaped electric heater, temperature rise probe, and thermal resistance in the mold are measured using a voltmeter. If there is damage, it should be replaced in a timely manner and compared with the mold's personal resume, keeping records, and adopting corresponding measures for moderately discovered problems.
