[0002] Lost foam is a new casting method that uses a foam plastic mold that uses dry sand without adhesive and vacuum technology to cast a solid mold. It is a foam model with a similar size and shape to the casting that is bonded together into a model cluster, coated with refractory paint and dried, and then buried in dry quartz sand for vibration molding. The model is poured under negative pressure to vaporize the model, and the liquid metal occupies the model position, which is then solidified and cooled to form a casting.

[0003] The lost foam is made of plastic particles. During the manufacturing process, the surface of the formed lost foam has a certain degree of adhesion, which causes the formed lost foam to stick to the inside of the mold. When demolding, it is difficult to demold the lost foam from the mold by hand, resulting in a very troublesome process of demolding the lost foam, which has certain limitations.

[0004] In view of the above problems, the utility model provides a lost foam molding die which is easy to take out. Utility Model Content
