Abstract
The utility model provides an iron mold sand coated sand box for a 6-cylinder cylinder cover, which relates to a casting technology. At least two upper sand box sand shooting holes (106) and upper sand box gas exhaust holes (103) are formed at the top end of the middle part of an upper sand box (1); an upper sand layer (102) is coated on the cavity wall of the sand box; an upper sand box runner (104) is formed in the middle of the side wall of the sand box; at least two lower sand box sand shooting holes (206) and lower sand box gas exhaust holes (203) are formed at the top end of the middle part of a lower sand box (2); a lower sand layer (202) is coated on the cavity wall of the sand box; and a lower sand box runner (204) is formed in the middle of the side wall of the sand box. The produced cylinder cover is greatly improved in appearance, the size accuracy is enhanced, the machining allowance is reduced, the production efficiency of products is increased, high iron type steel degree of the cylinder cover is achieved, the self-feeding ability is enhanced, high iron form cooling speed is achieved, crystalline structures are refined, the fineness of the crystalline structures are enhanced, and a leakage defect of the cylinder cover is reduced.
Description
Technical field
The utility model relates to foundry engieering, especially a kind of 6 cylinder cylinder head device for sand coated iron mould sandboxes.
Background technology
What cylinder cover for diesel engine generally adopted is the outer mold forming of wet type external mold or resin type, owing to after having the unstability and graphitization expansion of molten steel solidification, because the external mold modification easily causes micro-shrinkage porosite, causing combustion chamber fatigue strength to reduce the defectives such as dribbling of injection nozzle.
Summary of the invention
The purpose of this utility model provides a kind of solution because of the external mold poor rigidity, and causes the product material loose, causes performance to reduce, and adopts the sandbox inner chamber to be covered with 6 cylinder cylinder head device for sand coated iron mould sandboxes of layer of sand.
Technical scheme that the purpose of this utility model adopts comprises cope and drag box; Middle part, described cope both sides has cope locating hole, top and the bottom to be provided with the cope bolt connecting hole, the box outer wall both sides have cope to hang handle; Middle part, described drag box both sides has drag box locating hole, top and the bottom to be provided with the drag box bolt connecting hole, the box outer wall both sides have drag box to hang handle; Its top, cope centre is provided with at least two above cope sand-spraying holes and cope steam vent, internal chamber wall are covered with layer of sand on one deck, there is the cope running channel sidewall centre; Top, drag box centre is provided with at least two above drag box sand-spraying holes and drag box steam vent, internal chamber wall are covered with layer of sand under one deck, there is the drag box running channel sidewall centre.
The utility model, the axial line of cope locating hole and drag box locating hole is on the same line.
The utility model, the axial line of cope bolt connecting hole and drag box bolt connecting hole is on the same line.
The utility model, cope running channel and drag box running channel interlock, and are combined into a running channel.
The utility model, the thickness of upper layer of sand and lower layer of sand is 2-8mm.
The utility model, institute's production cylinder head is from greatly being improved in appearance, and dimensional accuracy improves, and has reduced allowance, has improved the production efficiency of product, and cylinder head swage stiffness is high, has improved from the feeding performance; The swage cooling velocity is fast, refinement crystalline structure, improved the fine and closely woven property of crystalline structure, reduced the defective of cylinder head seepage.
