Medical Mould-Plastic Mould Maintenance: 7 Things

  • click to rate

     Plastic mould is the key special tool for plastic products. If the quality of the mould changes, such as: changes in shape, position shift, roughened moulding surface, and inadequate contact on the mould clamping surface, it will directly affect the quality of plastic products. Therefore, we must pay attention to the use and maintenance of the mould.

           
    The main points are as follows:

          
    (1) Before production, check all parts of the mould for impurities. Dirt, the paint, impurities and dirt in the mould should be removed by scrubbing with cotton gauze, and the residue with strong adhesion should be cleaned with copper tools.

          
    (2) Reasonably select the clamping force, which is based on the fact that no flash occurs when the product is formed. Excessive clamping force not only increases the power consumption, but also makes the mould and transmission parts accelerate the wear speed.

          
    (3) mould sliding parts such as guide post, push rod, reset rod, pull rod, etc., are oiled twice a day in summer and only once in winter.

         
     (4) The full-time mould maintenance workers shall carry out patrol inspection and observation on the moulds in production when they are on duty, and timely deal with any problems found. Security workers should take up the job 5 to 10 minutes in advance to check the production status of the mould-especially for those moulds that often have inferior products, the more problematic and more prominent moulds, more attention should be paid.

          
    (5) In production, power outages and shutdowns occur for any reason. For continuous downtimes of more than 6 hours, during the rainy season in the south, when the air is humid, the moulding surface, parting surface, and sliding surface need to be sprayed with rust preventive oil. In non-rainy season, if the machine is stopped continuously for more than 24 hours, the mould forming surface, parting surface and sliding mating surface should be sprayed with anti-rust lubricant. Moulds that need to be put into inventory temporarily should be thoroughly cleaned before being put into the warehouse, then sprayed with anti-rust lubricant, and the moulds should be put into the warehouse after being closed. Do not place heavy objects on the mould.

          
    Do not hit any parts in the mould with a hand hammer to prevent knock marks or deformation.

          
    (7) The equipment is temporarily unused, and the mould on the injection should be coated with anti-rust oil. It is not allowed to stay under pressure for a long time between the mould moving and the fixed mould to prevent compression deformation.
