Core tips: 1. Purpose: to ensure the normal production of molds, reduce faults and quality problems, and prolong the service life of molds<\/a><\/strong>. 2. Scope of application: molds in mass production of injection molding department, excluding trial molds. 3. Daily maintenance 3.1 each shift (12h) shall be maintained by the responsible technician and recorded in the operation day report. 3.2 maintenance items: 3.2.1 wipe and clean the glue wire and dirt on the front and rear mold surfaces; 3.2.2 check bullet<\/p>\n\n\n\n

1. Purpose: to ensure the normal production of the mold, reduce faults and quality problems, and prolong the service life of the mold.<\/p>\n\n\n\n

2. Scope of application: molds in mass production of injection molding department, excluding trial molds.<\/p>\n\n\n\n

     3. Daily maintenance<\/p>\n\n\n\n

     3.1 each shift (12h) shall be maintained by the responsible technician once and recorded in the operation day report.<\/p>\n\n\n\n

     3.2 maintenance items:<\/p>\n\n\n\n

     3.2.1 wipe and clean the rubber wire and dirt on the front and rear mold surfaces;<\/p>\n\n\n\n

     3.2.2 check whether the spring, thimble and row position are stuck, burned and broken. If so, drop the mold for repair;<\/p>\n\n\n\n

     3.2.3 check whether the water transportation is blocked, and dredge it if any;<\/p>\n\n\n\n

   3.2.4 add butter to the movable parts such as thimble, row position, guide post and guide sleeve.<\/p>\n\n\n\n

4. Regular maintenance<\/p>\n\n\n\n

     4.1 divide the modulus of each maintenance according to the model size of the injection molding machine, and calculate it by dividing the output counted in the production order by the number of holes. The maintenance is carried out by the repair module, and the mold administrator records it on the mold resume:<\/p>\n\n\n\n

     30t ~ 100t: maintain every 60000 molds produced<\/p>\n\n\n\n

     150t ~ 160t: maintain every 50000 molds produced<\/p>\n\n\n\n

     220t ~ 350t: maintain every 40000 molds produced<\/p>\n\n\n\n

     4.2 maintenance items:<\/p>\n\n\n\n

     4.2.1 wipe and clean the rubber wire and dirt on the P \/ L surface;<\/p>\n\n\n\n

     4.2.2 check whether the spring, thimble and travel position are stuck, burned and broken. If so, drop the mold for repair;<\/p>\n\n\n\n

     4.2.3 check whether the water transportation is blocked, and dredge it if any;<\/p>\n\n\n\n

     4.2.4 add butter to the movable parts such as thimble, row position, guide post and guide sleeve;<\/p>\n\n\n\n

     4.2.5 disassemble the thimble, row position, core pulling, and check whether there are burns, fractures, serious wear and other phenomena. If any, repair or replace it;<\/p>\n\n\n\n

     4.2.6 clean the exhaust grooves and holes, and exhaust the parts with trapped gas and black burning;<\/p>\n\n\n\n

     4.2.7 correction of damaged and worn parts.<\/p>\n\n\n\n

5. Appearance maintenance:<\/p>\n\n\n\n

     5.1 the mold administrator and upper and lower mold technicians are responsible for the appearance maintenance<\/p>\n\n\n\n

     5.2 maintenance items:<\/p>\n\n\n\n

     5.2.1 paint the outside of the mold embryo to avoid rust;<\/p>\n\n\n\n

     5.2.2 during mold dropping, the cavity shall be sprayed with antirust oil;<\/p>\n\n\n\n

     5.2.3 it shall be tightly closed during storage to prevent dust from entering the mold core.<\/p>\n\n\n\n

 6. Precautions for mold maintenance<\/p>\n\n\n\n

     6.1 refueling is required for daily maintenance of moving parts;<\/p>\n\n\n\n

    6.2 the mold surface must be clean: do not stick label paper on the P \/ L surface; It is forbidden to continue beer without taking out the product sticking mold; The P \/ L surface rubber wire must be cleaned.<\/p>\n\n\n\n
