Abstract

The invention discloses a kind of no fash valve body mouldings, including sprue gate, casting ontology, sand core, first level runner and vertical run, one end of the casting body upper surface is equipped with sprue gate, the vertical run is connected to by the third auxiliary flow of middle position with one end of first level runner, and first level runner runs through the upper end of casting body interior sand core, the other end of the first level runner is connected to by AC port with the second horizontal run, and the second horizontal run runs through the bottom end of sand core.The present invention is by making the splicing of main sand core into main sand core global formation, main sand core is spliced by 10 small sand core again, loam core stitching portion uses high-strength novel binder, it ensure that stitching portion will not be broken when molten iron enters cavity, it also solves the problems, such as batch seam in main sand core runner simultaneously, leads to cavity by the way that a sprue gate is arranged, and by horizontal run, the dosage for reducing molten iron and riser, saves production cost.

Description

A kind of no fash valve body moulding
Technical field
The present invention relates to staircase casting equipment technical field, specially a kind of no fash valve body moulding.
Background technology
Though China is at present construction machinery production big country, industry is greatly without strong, low-and-medium-grade products excess capacity, high-grade liquid Element almost all is pressed to rely on import, the development of Hydraulic Industry seriously lags behind the development of host industry, becomes restriction as equipment The main bottleneck of development of manufacturing.Currently, China's hydraulic part industry integral fabrication technique level compared with international advanced country still There is larger gap.Project Product is as construction machinery hydraulic system key components and parts, high, the highly reliable, service life with integrated level The advantages that long, Project Product is high in technological content, alternative import, while can also for export, and product embodies higher casting Technical merit maintains the leading position at home.Project Product purposes is extremely wide, and market demand is larger, promise well.But The main core hole of valve inner is also easy to produce batch seam at present, and is not easily cleaned.
Invention content
The purpose of the present invention is to provide a kind of no fash valve body mouldings, to solve mentioned above in the background art ask Topic, possessed advantageous effect are:Make main sand core global formation by splicing main sand core, then is spliced by 10 small sand core and led Sand core, loam core stitching portion use high-strength novel binder, ensure that stitching portion will not be broken when molten iron enters cavity, simultaneously Also it solves the problems, such as batch seam in main sand core runner, leads to cavity by the way that a sprue gate is arranged, and by horizontal run, reduce The dosage of molten iron and riser, saves production cost.
To achieve the above object, the present invention provides the following technical solutions:A kind of no fash valve body moulding, including sprue gate, One end of casting ontology, sand core, first level runner and vertical run, the casting body upper surface is equipped with sprue gate, cast Mouth is connected to the vertical run of casting body interior, and the vertical run passes through the third auxiliary flow of middle position and first One end of horizontal run is connected to, and first level runner runs through the upper end of casting body interior sand core, the first level runner The other end be connected to the second horizontal run by AC port, and the second horizontal run runs through the bottom end of sand core, on the sand core Equipped with uniform reinforcing rib, the side of the casting ontology is equipped with ten sand-spraying holes, and air hole is equipped between sand-spraying hole.
Preferably, the high exothermic riser of chill is equipped at the sprue gate.
Preferably, the sand core has ten, and is divided into the inside that two row are arranged symmetrically in casting ontology.
Preferably, the AC port is connected to by the first auxiliary flow with the sand core of AC port side.
Preferably, the bottom end of the vertical run is connected to by the second auxiliary flow with the sand core of vertical run side.
Compared with prior art, the beneficial effects of the invention are as follows:The equipment is whole by making the splicing of main sand core into main sand core It is body formed, then main sand core is spliced by 10 small sand core, loam core stitching portion uses high-strength novel binder, ensure that stitching portion exists Molten iron will not be broken when entering cavity, while also solve the problems, such as batch seam in main sand core runner, by the way that a sprue gate is arranged, And cavity is led to by horizontal run, reduce the dosage of molten iron and riser, saves production cost.
