Embodiment Construction
[0038] The present invention is specifically described below by way of embodiment, and present embodiment is only used to further illustrate the present invention, but can not be interpreted as the restriction to protection scope of the present invention, some non-compliances that those skilled in the art make according to the content of the present invention above-mentioned Essential improvements and adjustments also belong to the protection scope of the present invention.
[0039] The invention provides a dismantling structure of an engine cylinder sand core mold and a molding process using the dismantling structure. In the casting process of the engine cylinder block, different crankcases have different complexity of the main core structure. For the complex main core structure, due to the uneven planes on both sides of the shaft seat, a special-shaped surface is formed. Usually, in order to simplify the mold , improve production efficiency and product quality, and adopt a s...

The invention discloses a sand core mold structure of an engine cylinder body and a molding process thereof. The mold structure includes the main core of the engine cylinder block composed of the cylinder, the shaft seat and the oil pan, and the shaft seat is composed of the shaft seat core and the primary core matched and combined with the shaft seat core; the split structure of the present invention is beneficial to the engine block main core Standardized processing and modeling, the special-shaped surface with special structure is processed separately, which is more accurate and efficient in the overall modeling processing; the main core with the special-shaped surface is divided into two core-making during the molding processing of the present invention, and the When the core is used, the mold can still be split from the center of the cylinder, and the main core with the special-shaped surface can be made into a whole core. Among them, the primary core is the mold part when the mold is closed, and the main core part when the mold is taken. This method not only ensures the quality of the main core, but also makes the way of taking the main core simple and fast.
Description
technical field [0001] The invention belongs to the field of mechanical design and manufacturing, in particular to the technical field of mechanical casting, and in particular to a sand core mold structure for an engine cylinder body and a molding process thereof. Background technique [0002] In the casting production process, the design and molding process of the mold directly affect the production efficiency and casting quality. When the structure of the casting is complex, the traditional method cannot meet the needs. Such as the crankcase, the casting has high requirements on the cylinder barrel and the axle seat, and the cylinder barrel and the axle seat are formed by the main core during the resin sand molding process, and the quality of the sand core of the main core is critical. Therefore, when designing the model, it is usually considered to split the mold from the center of the cylinder, and the main core can be made into a whole core to ensure the quality. Howe...
