  plastic part mould means that in order to obtain the structural shape of the part, the structural shape of the part is made in advance with other easily formed materials, and then the mold is placed in the sand mold, so a cavity with the same size as the part structure is formed in the sand mold , And then pour a fluid liquid in the cavity. After the liquid is cooled and solidified, a part with the same shape and structure as the mold can be formed.
  Cleaning of car parts mould:
  　　 At present, domestic and foreign companies use a variety of cleaning methods in core box cleaning:
  　　 1. Use chemical cleaning agent to clean.
  　　2. Use dry ball jet method to clean the core plate.
  　　3. Use liquid or solid sandblasting machine for sandblasting and cleaning.
  　　 Use a liquid sandblasting machine, the compressed air pressure is 0.5～0.7MPa, and the spraying distance is about 10～120mm. The cleaning medium uses glass pellets with a particle size of 90um or white corundum sand with a particle size of 0.125mm (120 mesh) to clean and maintain (or scale) the core box. In general, the core box is regularly cleaned and maintained for ≤1—2min. The cleaning time of the core box of resin fouling depends on the size of the core box, the thickness of the fouling, and the complexity of the shape. Usually, the fouling of the core box can be cleaned in the range of 5-20 minutes, and the spray time has an effect on the dimensional accuracy of the core box. And surface roughness basically has no effect. The process of using liquid sandblasting machine and glass pellets to clean the core box can basically clean the thick resin fouling on the surface of the core box, but it is difficult to clean the thick grooves that have not been cleaned for a long time.
