Cars are generally composed of four basic parts: engine, chassis, body and electrical equipment. The engine is the power device of the car, which is composed of the body, the crank connecting rod mechanism, the valve train, the cooling system, the lubrication system, the fuel system and so on. According to the type of fuel, it can be divided into diesel engine, gasoline engine and natural gas engine, etc.; according to the working mode, it can be divided into two-stroke and four-stroke.

The body is the skeleton of the engine and the installation basis for the various mechanisms and systems of the engine. The body group is mainly composed of cylinder blocks, crankcases, cylinder heads, cylinder gaskets and other parts. The cylinder head is one of the important parts of the engine. According to the structure, the cylinder head can be divided into single-cylinder cylinder head and multi-cylinder connected cylinder head. According to the material, it can be divided into two categories: non-ferrous metal and ferrous metal. The main production method of multi-cylinder conjoined cylinder head castings made of ferrous metal is sand casting. In the sand casting process, it is divided into horizontal pouring process and vertical pouring process according to the state and position of the cylinder head combustion chamber surface in the sand mold; the production of multi-cylinder continuous When the body cylinder head is used, the production mode of one-type two-piece vertical casting process is often adopted. At this time, two cylinder head sand cores need to be combined to form a whole sand core, and the position of the two sub-sand cores in the combined whole sand core is required. In contrast, at the same time, the combustion chamber surface of the cylinder head in the integral sand core is required to be in a vertical state, which has higher requirements for the core assembly process of the two sub-sand cores.

It should be noted that the "side-by-side arrangement" in the article refers to the distribution of two sub-core groups in a straight line in the horizontal and horizontal or horizontal and vertical directions, which can ensure that after the two sub-core groups rotate, they only need to move in one direction. , the sub-core groups of the two sub-core groups can be bonded together without misalignment. In a specific solution, the above-mentioned two sub-core groups can be rotated to the inside of the two sub-core groups, so that the combustion chamber surface can be rotated to a vertical position only by rotating 90 degrees, which is the simplest process of the above-mentioned core assembly process. implementation.

With such a structure, hold the anti-rotation handle 85 and exert force outward, which can drive the screw 84 and the insertion shaft 83 to move outward at the same time. Since the shaft sleeve 81 does not move, the spring is compressed, and at the same time, the inner end of the insertion shaft 83 is disengaged. The second through hole enables the rotating shaft to rotate freely; when anti-rotation is required, only the anti-rotation handle 85 needs to be loosened, and under the action of the spring, the insertion shaft 83 moves inward into the second through hole to play the role of anti-rotation .
