Abstract
A split type single-cylinder water-cooled diesel engine body structure comprises an upper engine body, a lower engine body, a locating pin and a sealing material, wherein the upper engine body and a lower engine body are connected into a whole through locating of the locating pin, so that a complete single-cylinder water-cooled diesel engine body is formed. According to the scheme, the casting technology of the diesel engine body can be optimized, and integral sand casting of the diesel engine is changed into metal mold pressure casting, so that the uniformity of the thickness of the wall of the diesel engine body is ensured, sand casting defects such as cold shut, shrinkage, shrinkage porosity and the like are reduced, material consumption is reduced, the yield is increased, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of split type single-cylinder water cooled diesel engine housing construction, belongs to mechanical field.
Background technique
At present, the body of domestic single-cylinder water cooled diesel engine is overall structure, mostly adopts sand casting process, and the wall thickness of the diesel-engine body of this moulding by casting is large, and casting technique is complicated, and materials consumption is high, and castability is difficult to guarantee.Due to sand mold the soft and porous of bulk property, cause that sand casting process dimensional accuracy is low, rough surface, so cause foundry goods easily to produce cold shut, shrinkage cavity shrinkage porosity, scab, the unequal defect of appearance; Because the core of sand casting process can only be used once, obtain foundry goods after core damage, then use moulding again, so the manufacturing efficiency of sand casting process is lower; Adopt sand mold to make mold and must use sand, Bond, baking box etc., use sand damage to land or marine resources, Bond belongs to industrial chemicals, and mold is dried the baking box using and is wasted energy in a large number, sand casting process dust polluting environment, make casting become a heavy polluted industry, while labor strength is large, poor working environment.So further reduce production costs, enhance productivity, reduce environmental pollution, become those skilled in the art's problem demanding prompt solution.For this reason, we design and have invented a kind of split type single-cylinder water cooled diesel engine housing construction, can realize body die cast, good manufacturability, reliable in quality, production process can realize green, energy-conservation object, can realize production in enormous quantities, reduced cost of production, good economy performance, the market competitiveness of raising single-cylinder water cooled diesel engine.
Summary of the invention
The purpose of this utility model is to provide a kind of split type single-cylinder water cooled diesel engine housing construction, skill in the casting of its energy Optimization of Diesel Engine body, make diesel-engine body change metal pattern die casting into by unit sand mold casting, can guarantee the uniformity of diesel-engine body wall thickness, reduce the sand mold casting defects such as cold shut, shrinkage cavity and porosity, can reduce materials consumption again, improve yield rate, reduce production costs.
The technological scheme that the utility model patent is taked is as follows:
A split type single-cylinder water cooled diesel engine housing construction, is characterized in that: comprise upper machine body, lower body, locating stud, sealing material, upper machine body and lower body, by linking into an integrated entity, form a complete single-cylinder water cooled diesel engine body.
Further, upper machine body and lower body are equipped with interface.
Further, on the interface of upper machine body and lower body, be equipped with two above and corresponding positioning pin holes.
Further, realize by locating stud the location between upper machine body and lower body.
Further, on the interface of upper machine body and lower body, be equipped with several corresponding attachment holes.
Further again, between upper machine body and lower body, be provided with sealing material.
Owing to having adopted above-mentioned split-type structural, can carry out body die casting, improved product workmanship, reduced cost of production, reduced environmental pollution, improved workman's working condition, reduced labor strength, improved the competitiveness of product in market.
