Core box structure for manufacturing integrated sand core of diesel engine

Abstract

The invention discloses a core box structure for manufacturing an integrated sand core of a diesel engine. The core box structure for manufacturing the integrated sand core of the diesel engine comprises a core box body. A supporting seat body is arranged on the outer side of the core box body. A supporting block is further arranged on the outer side wall of the core box body. The supporting block is provided with a supporting shaft in a penetrated manner, and the supporting shaft is used for being connected with the supporting seat body and the core box body. The core box body is further provided with a sand core mechanism. The two ends of the sand core mechanism are provided with supporting rotary shafts. Rotating grooves are arranged at the supporting rotary shafts and the edges of the core box body. Each rotating groove is provided with a connecting flange which is used in cooperation with the rotating groove. A seal connecting piece is arranged between each rotating groove and the corresponding connecting flange. The core box structure for manufacturing the integrated sand core of the diesel engine protects the core box against the sand leaking phenomenon and the coking phenomenon through the improvement on the structure of the core box, normal operation of equipment is guaranteed, the overall production and machining quality of the diesel engine is improved, the service life of the equipment is prolonged, and actual use requirements are met.

Description

technical field [0001] The invention relates to a core box structure for preparing an integral sand core of a diesel engine, belonging to the technical field of core boxes. Background technique [0002] The internal combustion engine is a complex energy conversion machine. With the continuous improvement of the level of science and technology, the structure and arrangement of various types of internal combustion engines are also different. Using diesel as fuel, when the air is compressed in the cylinder to generate high temperature, the injected diesel is natural, and the internal combustion engine that expands the gas to do work is called a diesel engine. The power coverage of diesel engines currently produced in my country is 2.2-47280KW, the cylinder diameter of diesel engines is 65-900mm, and the speed is 5.6-4400r / min. Features: easy to start, easy to operate and maintain, compact structure, small size, light weight, easy to transport and install, good economy, wide ra...
