Maintenance of Household Product Mould After Shutdown from xiu's blog


1. When the operation needs to be temporarily stopped, the Household Product Mould(FURNITUREMOULD) should be closed to prevent the cavity and the core from being exposed to prevent accidental damage. The downtime is expected to exceed 24 hours, and the surface of the cavity and core should be sprayed. Rust oil or mould release agents, especially in wet areas and rainy seasons, should be rust-proofed for a short time. The moisture in the air will reduce the surface quality of the cavity and the surface quality of the product will decrease. When the household product mould is used again, the oil on the mould should be removed and wiped clean before use. The cleaned compressed air required by the mirror surface is dried and then dried with hot air, otherwise, it will ooze out during moulding and cause defects in the product.

2. After the temporary shutdown, turn on the machine. After opening the household product mould, check whether the slider limit is moved. If no abnormality is found, the mould can be closed. In short, be careful before starting the machine, not careless.

3. In order to extend the service life of the cooling water channel, when the household product mould is deactivated, the water in the cooling water channel should be immediately removed with compressed air, and a small amount of oil should be put into the mouth of the nozzle, and then compressed air is blown to make all the cooling pipes. There is a layer of anti-rust oil.

4. Carefully check the working status of each control unit during work to prevent abnormalities in the auxiliary system, heating, and maintenance of the control system is especially important for hot runner moulds. At the end of each production cycle, rod heaters, belt heaters, and thermocouples should be measured with the mother-in-law and compared with the technical description of the mould to ensure that the function is intact. At the same time, the control loop may be tested by an ammeter mounted in the loop. The oil in the hydraulic cylinder for core pulling is drained as much as possible, and the nozzle is sealed to prevent the hydraulic oil from leaking out or polluting the surrounding environment during storage and transportation.

5. If you hear any abnormal sounds or other abnormalities in the household product mould during production, you should immediately stop the inspection. The mould maintenance personnel shall conduct a patrol inspection on the normal running moulds in the workshop. When abnormal phenomena are found, they shall be dealt with in time.

6. When the operator is in the handover class, in addition to handing over the production, the process is closely related to the record, and the use status of the household product mould must be detailed.

7. When the household product mould completes the production quantity of the product when replacing the other household product mould, the mould cavity should be coated with an anti-rust agent, and the mould attachment should be sent to the mould maintenance staff, and the last piece of production is qualified. The products are sent to the maintenance staff as a sample. In addition, you should also send a mould use list, fill in the machine on which the mould is used, how many products are produced from a certain month of the year, and whether the mould is good now. If there is a problem with the household product mould, it is necessary to fill in the mould on the used sheet, propose the specific requirements for modification and improvement, and submit an unprocessed sample to the custodian, and leave it to the mould to repair the mould.

8. After the machine is stopped, check the surface of the household product mould for residual glue. After cleaning the foreign material, evenly spray the anti-rust agent and fill in the relevant records accurately.
