A core assembly production line and core assembly process for casting mold cores for engine cylinder blocks

Abstract

The invention provides a core assembling production line of an engine cylinder block casting die core and a core assembling process of the engine cylinder block casting die core. The core assembling production line of the engine cylinder block casting die core comprises a first core assembling wire body and a second core assembling wire body which are arranged in parallel, wherein the first core assembling wire body is provided with a first core assembling station; and the second core assembling wire body is provided with a second core assembling station, a third core assembling station, a fourth core assembling station and a fifth core assembling station. The core assembling production line of the engine cylinder block casting die core provided by the invention is matched with a sub-step core assembling process so that the combination of a whole core set is realized, and the positioning precision and the connection reliability of a sand core are improved; a sand core drifting phenomenon caused by the fact that molten iron impacts in a pouring process is avoided, so that the wall thickness of a cylinder block is controlled in a range being not more than 3.5mm+ / -0.5mm; and the technical requirements of the casting of the engine cylinder block are met.

Description

technical field [0001] The invention relates to the field of casting technology, in particular to a core assembly production line and core assembly process for engine cylinder casting mold cores. Background technique [0002] With the development of my country's automobile industry, automobiles have entered the families of ordinary consumers. As the main means of transportation in people's lives, automobiles not only bring convenience to people's travel, but also increase the burden of environmental cycle purification. In order to reduce the pollution of automobile exhaust to the atmospheric environment and achieve the goal of energy saving and emission reduction, the design concept of "light weight" has become the direction of future automobile development. As we all know, the engine of a car model occupies a large proportion of the vehicle's weight, and the weight of the engine is mainly concentrated in the cylinder body. Therefore, improving the quality of the engine cyli...
