Description

Technical Field

[0001] The invention relates to the technical field of molds, in particular to a multi-station demoulding mechanism and a grouting demoulding method. Background Art

[0002] The slip injection molding process is more complicated and requires a long drying time, but it is suitable for molding more complex shapes. Usually, the green embryo formed by compression molding or slip injection molding has a relatively low density. The green embryo will first be increased in relative density by an equalizing device before sintering. However, the equalizing device is expensive and difficult to produce large components, so the application level cannot be expanded. During the molding process, it is usually necessary to add a dispersant to enhance the dispersion of the powder, a binder to increase the strength of the green embryo, a release agent to facilitate the removal of the green embryo from the mold, and a lubricant to reduce the friction between the powders.

[0003] Grouting has become the focus of technology development in recent years. The traditional grouting method is used to make plate-shaped green embryos. Usually, two or more plaster molds are used to absorb moisture on all sides or both sides. This can accelerate the absorption of liquid in the mud and shorten the molding time. The structure of grouting products on the market is becoming more and more complicated, and the products usually have undercuts.

[0004] However, since the undercut cannot be separated, the existing mold cannot separate from the undercut, making it difficult for the undercut part to be smoothly separated from the core, and it is difficult to free up a certain shrinkage space for the product with the outer wall undercut.
