How to standardize the management of plastic molds and ensure their service life? The following editor of Xingye Plastic Mold Factory will introduce the method of standardizing the management of plastic molds. 1. The blade must be sharpened after long-term use. After grinding, the knife-edge surface must be degaussed and non-magnetic, otherwise it is easy to block the material.

The user should make detailed records and statistics of its use, maintenance (lubrication, cleaning, rust prevention) and damage, so as to know which parts and parts have been damaged and the degree of wear, so that they can find and solve the problem on the mold and use it for the mold Provide information on the process parameters and materials, shorten the trial production time, and improve production efficiency. For the normal operation of injection molding machines and plastic molds, the performance of the molds should be tested, and the dimensions of the molded plastic parts should be measured. According to this information, it can be judged whether the mold is damaged, cavity, core, cooling system, parting surface, etc.

Through the information provided by the plastic parts, judge the damage of the mold and the maintenance measures. 2. Elastic components such as springs are easily damaged during use and often break and deform. The method of use is to replace.

When replacing, you must pay attention to the model and specification of the spring. Product specifications and models are determined by three items: color, outer diameter, and length, and can only be replaced if the three items are qualified. The quality of clockwork is better than imported.

3. When stamping, it is easy to break and bend during the stamping process. Punches and punch kits generally use parts of the same size. The punch processing parameters mainly include workpiece size, mounting part size, length size, etc.

4. Fasteners, check whether the fasteners are loose or damaged, and replace them with parts of the same specification. 5. Compression, such as compression, film, etc. And unloading components, for example, stripping boards, pneumatic ejection, etc.

When repairing, check the relationship between parts and whether they are damaged, repair damaged parts, check whether there is air leakage by pneumatic jacking, and take measures in specific situations. Replace air tube if damaged. Some important parts of the mold need to be focused on tracking and testing: The release and guide parts are used to ensure release and ejection of the molded part.

If a part is stuck due to damage, production will stop. Therefore, the lubrication of the ejector pin and guide post of the mold should be maintained frequently (the most suitable lubricant should be selected), and the ejector pin and guide post should be checked regularly for deformation and surface damage. After the production cycle is over, special anti-rust oil should be applied to the surface of the mold, moving parts and guide rails, especially the bearings with gears and racks and the elastic strength protection of the spring mold to ensure that they are always in good working condition. , with the extension of production time, scaling, rust, sediment, algae, etc. are easy to occur in the cooling channel, which reduces the cross-section of the cooling channel. Due to the narrow cooling channel, the heat exchange rate between the coolant and the mold is greatly reduced, increasing the Therefore, the cleaning of the cooling channel should be paid attention to; the maintenance of the thermal control system can effectively prevent production failures.
