垂直分型无箱射压造型机的特点,射压方法紧实砂型,所得型块紧实度高而均匀,型块的两面都有型腔铸型由两个型块间的型腔组成,分型面是垂直的,连续造出的型块互相推合,形成一个很长的行列。一个型块即相当一个铸型,而射和压都是快速造型方法,具有生产率高、生产出的铸件尺寸精确,用砂节省、自动化程度高等许多优点,特别适用于无芯或少芯的中小铸件生产。
The feature of vertical type non box ejection molding machine is
that the injection pressure method compacts the sand mold. The shape of
the block is high and uniform. The two sides of the block are composed
of two type cavities. The type surfaces are vertical, and the continuous
type blocks are pushed together to form a long column. A type of block
is quite a mold, and both injection and pressure are fast molding
methods. It has high productivity, accurate casting size, and many
advantages such as sand saving and high automation. It is especially
suitable for the production of small and medium small castings without
core or core.
The molding characteristics of the horizontal split box ejection
molding machine are characterized by the use of sand shooting in the
upper and the lower types, and the direction of the sand shooting is
perpendicular to the template, without the shape of the shadow area, so
the compaction of the sand mold is more uniform, and the lower core is
carried out outside the machine and is convenient and safe, so it has
certain superiority, the core ejection machine but its sand barrel The
structure of compacted hydraulic cylinder is very complicated, and the
consumption of sand is large
