Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] Such as figure 1 shown.

[0039] A kind of diesel engine, gasoline engine cylinder head lost foam casting process, it comprises the following steps:

[0040] a. Divide the diesel engine, gasoline engine cylinder block or cylinder head to be cast into several splicing blocks or pieces, the cylinder head can be divided into such as figure 1 The four-piece structure shown in the figure (the double dotted line in the figure indicates the cutting surface), and the cylinder body can be divided into eight pieces or eight pieces, and each diesel engine, gasoline engine cylinder block or cylinder head after cutting the splicing block or The number and direction of the slices can be cut from the angle that is most conducive to pouring and splicing; then according to the shape and internal structure of the split slices or blocks, the same mold cavity as t...

Abstract

The invention discloses a method for casting disappear mould of the cover of diesel engine and petrol engine that based on disappear mould technique, which can solve the problems of present sand casting technique with high material consumption, heavy cast, and environment pollution, etc. The invention slices matter into several mould plates to prepare the mould; than filling the material of disappear mould into mould to attain the mould plate of disappear mould which is the same with said matter; dipping disappear mould dope on the mould plate and arranging it into sand tank to be vibrated and poured to melt mould plate into carbon monoxide and carbon dioxide to be discharged to attain the cast of said matter. The invention has the advantages that save raw material, reduce labor intensity and improve property.

Description

technical field [0001] The invention relates to a casting process, in particular to a metal pouring process for cylinder blocks and cylinder heads of diesel engines and gasoline engines, in particular to a lost foam casting process for cylinder blocks and cylinder heads of diesel engines and gasoline engines. Background technique [0002] As we all know, commonly used sand casting techniques include hot box, cold box, gravity casting, low-pressure casting, etc. These casting methods generally have high labor intensity, high raw material consumption, heavy casting weight, serious environmental pollution, poor precision, and demand A series of problems such as large machining workload. [0003] Diesel engine, gasoline engine cylinder block and cylinder head are the two key parts of motor vehicles. At present, casting and machining are generally used for production. Due to the complexity of its internal passages, it must be machined by opening holes on the casting surface accor...
