Repair and maintenance of the hottest production m

Maintenance of production molds

normal production of molds, reduce failures and quality problems, and extend the service life of molds

2. Scope of application: molds in mass production of injection molding department, excluding trial molds

3. Daily maintenance

3.1 technicians maintain once per shift (12h) and record it on the operation form

3.2 maintenance items:

3.2.1 front and rear mold surface glue wires, such as dirt wiping and cleaning

3.2.2 check whether the spring, thimble and row position are stuck, burned and broken, and if so, drop the mold for repair

3.2.3 check whether the water transportation is blocked, and dredge it if any

3.2.4 add butter to the ejector pin, row position, guide post, guide sleeve and other moving parts

4. Regular maintenance

4.1 divide the modulus of each maintenance according to the model size of the injection molding machine, calculate by dividing the output counted in the production order by the number of holes, and the maintenance is carried out by the repair module, And the mold administrator shall record it on the mold resume:

30t ~ 100t: maintain every 60000 mold production

150t ~ 160t: maintain every 50000 mold production

220t ~ 350t: maintain every 40000 mold production

4.2 maintenance items:

4.2.1p/l glue wire and dirt wiping and cleaning

4.2.2 check whether the spring, thimble and row position are stuck, burned and broken, and if so, drop the mold for repair

4.2.3 check whether the water transportation is blocked, and dredge it if any

4.2.4 add butter to the moving parts such as thimble, row position, guide post and guide sleeve

42. Adjust the front and rear levels of the experimental force sensor on the front of the swing rod 2.5 disassemble the thimble, line position, core pulling, and check whether there are burns, fractures, serious wear and other phenomena. If there is any, repair or replace it

4.2.6 clean the exhaust grooves and holes, and exhaust the parts with trapped gas and black burning

4.2.7 correction of damaged and worn parts

5. Appearance maintenance:

5.1 the appearance maintenance is carried out by the mold administrator and the upper and lower mold technicians

5.2 maintenance items 9. Operation must be carried out according to the procedures specified in the manual when using. Objectives:

5.2.1. Paint the outside of the mold embryo to avoid rust

5.2.2. When dropping the mold, the mold cavity should be sprayed with antirust oil

5.2.3. Close tightly during storage to prevent dust from entering the mold core

6. Precautions for mold maintenance

6.1 oil must be added for daily maintenance of active parts

6.2 the mold surface must be clean: do not stick label paper on the p/l surface; It is forbidden to continue to drink the product without taking out the mold; The p/l surface glue yarn must be cleaned up, which can accumulate in the food chain
