Embodiment Construction

[0033] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] Such as Figure 1-Figure 3 The figure provides a three-dimensional view of the overall assembly, pouring scheme layout and pouring system 5 of the gravity casting method for a diesel engine body of the present invention. The sand core group includes four main sand cores 1, two insert sand cores 2, waterway sand cores and There are two cam chamber sand cores 3 each, forming two groups of main sand cores 1, insert sand cores 2, waterway sand cores and cam chamber sand cores 3, and two groups of main body sand cores 1, insert sand cores 2, waterway sand cores and The sand core 3 of the cam chamber is arranged symmetrically in reverse in the horizontal direction, and the upper box and the lower box 4 are integrated to form two sets of diesel engine bodies. Such as Figure 4-12 They are the three-dimensional views of the mai...

Abstract

The invention discloses a gravity casting method of a diesel engine body, which comprises the following steps: manufacturing sand core groups by using a core shooter, wherein each group comprises a main body sand core, a male tab sand core, a water channel sand core and a cam chamber sand core; combining the multiple main body sand cores and the multiple male tab sand cores into a main body sand core group, and dip-coating and drying the whole body; placing the water channel sand cores into a lower case, then placing the main body sand core group into the lower case, and finally placing the cam chamber sand cores in the lower case; and combining an upper case and the lower case into a whole, and casting. The invention solves the problems that the production efficiency is low and the laborintensity of workers is high because the existing mold case can only produce one product each time.

Description

technical field [0001] The invention relates to a gravity casting method, in particular to a gravity casting method for a multi-cylinder diesel engine body. Background technique [0002] Diesel engine body is an important component of diesel engine. Diesel engine is a mature product. At present, the market demand is strong, but the output cannot keep up. One of the important reasons is that the production efficiency of the diesel engine body is not high. The shape of the existing diesel engine body is complicated, the mold is one piece in a box, the production efficiency is low, and the labor intensity of workers is high. All the main sand cores of the machine body are dip-coated separately, dried separately, and then manually assembled and set cores, which is labor-intensive and time-consuming, and the quality of castings is not easy to control. Contents of the invention [0003] The purpose of the present invention is to provide a diesel engine body gravity casting met...
