How to better maintain bottle cap mold
Edit:Taizhou Huangyan Yige Machinery Co., Ltd.   UpDate:2019-07-10

1. The processing enterprise should first give each pair of bottle cap mold equipment experience card, and record and calculate its use, care (smoothing, cleaning, rust prevention) and damage. According to this, you can find which parts and components have been damaged and the degree of wear and tear. In order to provide information materials for finding and solving problems, as well as the molding process parameters of the bottle cap mold and the materials used in the product, to shorten the test run time of the bottle cap mold and improve production efficiency.

2. Under the normal operation of the injection molding machine and the bottle cap mold, the processing enterprise should test the various performances of the bottle cap mold, and measure the size of the plastic parts after molding. Based on this information, the current status of the bottle cap mold can be determined. Find out the damage locations of the cavity, core, cooling system and parting surface, etc. According to the information provided by the plastic parts, you can determine the damage status and maintenance measures of the bottle cap mold.

3. Focus on the inspection of several important parts of the bottle cap mold: the function of the ejection and guide parts is to ensure the opening and closing movement of the bottle cap mold and the ejection of the plastic parts. If any part is jammed due to damage, it will cause Stop production, so you should always maintain the smoothness of the thimble and guide pin of the bottle cap mold (select a suitable smoothing agent), and check the thimble and guide pin regularly for deformation and appearance damage. Once found, replace it in time; complete a production After the cycle, the surface, movement and guide parts of the bottle cap mold should be coated with professional anti-rust oil. In particular, the protection of the elastic strength of the bearing parts of the mold with gears, rack and bottle caps and the mold of the spring caps should be paid attention to. To ensure that it is always in good working condition;

As the production time continues, scales, rust, silt and algae are easy to accumulate on the cooling channel, 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 bottle cap mold, and adds enterprise production Cost, so attention should be paid to the cleaning of the runner; for warm-run bottle cap molds, the maintenance of the heating and control system is helpful to avoid the occurrence of production failures, so it is particularly important. Therefore, after the end of each production cycle, tape heaters, rod heaters, heating probes, and thermocouples on the bottle cap mold should be measured with an ohmmeter. If there is damage, replace them in time and replace them with bottle caps. Compare the mold history table and make a record so that problems can be found on the spot and countermeasures can be taken.
