Embodiment Construction

[0013] The present invention will now be further described in conjunction with specific examples, and the following examples are intended to illustrate the present invention rather than further limit the present invention.

[0014] A manufacturing process of a single-cylinder diesel engine block, which is a casting process using a lost foam model composed of a white mold and a paint layer on the white mold, and the sand box with the pumping chamber is placed on a vibrating table , and clamp it tightly, put the bottom sand with a thickness of 60mm at the bottom, and vibrate it tightly. Put the lost foam model inside and fix it with sand. The gate is 3.5cm higher than the molding sand plane. The molding sand is dry quartz sand without binders, fillers, and no water; add dry quartz sand and apply three-dimensional vibration at the same time. , the vibration time is 43 seconds, so that the molding sand fills all parts of the model, and the accumulation density of the molding sand ...

Abstract

The invention relates to a manufacturing process of a diesel engine cylinder block, in particular to a manufacturing process of a single-cylinder diesel engine cylinder block. A kind of manufacturing technology of single-cylinder diesel engine block, this manufacturing technology is the technology that adopts the lost foam model that is made of white mold and the paint layer on the white mold to carry out casting, comprises following process steps: 1. Vibration molding: a. sand bed Preparation → b. Placing the lost foam model → c. Filling sand → d. Sealing and shaping, 2. Pouring replacement, 3. Cooling and cleaning. The invention solves the problem of low casting quality, thereby realizing the mass production of single-cylinder diesel engine cylinder blocks.

Description

technical field [0001] The invention relates to a manufacturing process of a diesel engine cylinder body, in particular to a manufacturing process of a single-cylinder diesel engine cylinder body. Background technique [0002] Single-cylinder diesel engine cylinder block is a relatively complex casting. At present, clay sand casting is mainly used in China, and a few enterprises use cold box or hot box casting, but the quality of castings cast by these casting methods cannot be guaranteed. Compared with sand casting, the lost foam casting process has unparalleled advantages: only a single model is required, it is environmentally friendly, the molding sand can be recycled, the castings have fewer defects, and the quality is guaranteed. In the prior art, the lost foam casting process is also used for the production process of the single-cylinder diesel engine block. There are many patent applications, but there is no mass production in China. In the lost foam casting process,...
