In order to ensure the service life and frequency of the mold, the following stipulations are made for the use, maintenance, maintenance, repair and preservation of the mould.

1) the new mold should be treated with the die wax first, and then the mold release agent should be treated. Processing method: release wax with a sponge dipped in wax stripping in a circular motion smear, the wax infiltration coating micro gap, while the wax is not dry, the surface of the mold coat shiny with a clean cotton wipe, repeated 5-6 times. The way to release the mould is to use a clean cotton cloth to dip a little mold release agent, so as not to drop, and apply it on the side of the die to the other side. The fish scale is laminated with 1/3 or 1/4, so as to avoid any missed coating and repeat it 5-6 times. Ensure that the interval between each and every time should not be less than 15 minutes. When the surface solvent volatilized 50%, a clean, dry cotton cloth was gently rotated and polished to the surface. Note that it must be cured for more than 1 hours to use. Note * second times after applying wax stripping can be pushed into the barn to be 35 to 40 degrees bake for 0.5 hours, and not less than 30 degrees in the mold temperature and rubbing off.

2) a qualified treatment can be carried out continuously for 3-5 times, and after 3-5 times the wax removal can be processed to ensure the release of the product. Note * every time after stripping to edge and shape part of the die for the release agent [] release wax treatment, so as not to damage caused by mold release effort.

3) note. Do not use metal tools and sharp tools in each forced demoulding demoulding, with leather hammer and plastic or wooden wedges to tap the products and die out.

4) if it is found that the brightness of the mold is not enough, the light is processed immediately. Note * polishing polishing paste smear can not apply once the area is too large, with 0.25 square meters. Otherwise, people will scratch the surface of the mold after stepping on it. After polishing, the release agent and wax are treated in accordance with the regulations.

5) every time after demoulding should check the mold edge and surface damage, mold damage generally have cracks, fall sticky gel. The main reason is the product of local coat crack with exothermic and stripping force concentration is not uniform, the main reason is to stick to the fallen gel mold treatment is not in place or omission. If the mold is damaged, it should be repaired in time. Note that in the continuous production. 20 products must be approved by the quality inspection department and workshop after technical staff to the surface and dimension of the die for testing, qualified to carry out the production. In case of disqualification, it will be repaired immediately, and only after being qualified can it be produced.

6) method for mold repair: first will damage parts with sandpaper breaking light, and then use the same mould gel fill in the injury site (crack or fall stick area is large, can be used to fill the spray gun to be completely cured gel, gel), 320#, 600#, 1000#, 1500# water sandpaper in order to use sandpaper grinding, direct hand grinding is not allowed, should be covered in smooth sandpaper wood or rubber, made of grinding block. The running track of the grinding block should be straight forward and back and back spiral. Every time it is required to wear the sand mark of the last grinding, when the 1500# sand paper is finished, there can be no trace of water and sand on the mold. After grinding, polishing with polishing paste 2# micron, polished to a mirror surface, and then on the basis of a first release agent, mold processing of wax. After completion of repair, the mold can be put into use.

7) make 30 products every time or check the skeleton and nylon wheel at any time. Whether there is opening welding, whether the nylon wheel bearing is short of oil or normal rotation, and has defects, repair and weld in time.

8) every batches of products must be put into stock before finishing the mold. The mold checking skeleton, nylon wheel and mold surface are all repaired before finishing, and then the mold release wax is processed on the die surface. Spraying a layer of gel coat resin, waste or waste paste felt surface a layer of solidified to ensure the mold surface in transportation and storage is being scratched. The corrosion of the mold skeleton inspection is corroded, and a layer of antirust paint is sprayed to prevent rust.

Check whether the mold is complete and complete. Mark the figure on the back or surface of the mold with the paint. The next use is to look up.
