Diesel engine body exterior die of large medium-speed ship

Abstract

The invention discloses a diesel engine body exterior die of a large medium-speed ship. The diesel engine body exterior die of the large medium-speed ship comprises a gating system layer, an exterior upper half layer, and an exterior lower half layer, wherein the gating system layer comprises a first gating system insert, a second gating system insert and a third gating system insert; the exterior upper half layer comprises a left upper insert and a right lower insert; the exterior lower half layer comprises a left lower insert and a right lower insert. The diesel engine body exterior die of the large medium-speed ship is compact in structure; the exterior die is a three-layered structure including the gating system layer, the exterior upper half layer and the exterior lower half layer. All the inserts are connected and fastened through dowel location and bolt fastening, so that the diesel engine body exterior die is convenient to mount and dismount. By virtue of the design structure of the elliptical core mark inserts and the mistake-proofing core mark inserts, formation of a die circular bead is reduced, so that the workload for cleaning the circular bead is reduced, the difficulty for a bench worker to clean the bead is reduced, and the die manufacturing efficiency is improved.

Description

technical field [0001] The invention relates to the field of large-scale medium-speed marine engines, in particular to a large-scale medium-speed marine engine body exterior mold. Background technique [0002] The existing large-scale medium-speed marine diesel engine body has large volume, heavy weight, difficult processing, and difficulty in lifting and assembling; in addition, the rounded corners on the mold are difficult to clean, and the labor intensity of the fitter is high, resulting in the outer appearance of the large-scale medium-speed marine diesel engine body. Mold manufacturing and processing efficiency is low. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned defects in the prior art, the present invention provides a large-scale medium-speed marine engine body shape mold with compact structure, convenient disassembly and assembly operation, reduced difficulty of fitter cleaning, and high mold manufacturing efficiency. [0004] In ord...
