Universal negative type combined model used in production of diesel engine flywheel with iron mold coated sand

Abstract

The invention relates to a universal negative type combined model used in production of a diesel engine flywheel with iron mold coated sand. The combined model comprises a flywheel standard template pedestal, a flywheel lower template, a flywheel lower iron mold, a standard interface and a drag water cooling injection plate; the model is characterized in that the flywheel lower template is arranged on the flywheel standard template pedestal and is fixedly connected with the flywheel standard template pedestal through a fillister head screw, a flywheel lower mold sample is assembled on the flywheel lower template, is positioned by a positioning pin and is then fixedly connected with the flywheel lower template through a fillister head screw, the flywheel lower template and a sprue are fixed by a screw, the flywheel lower iron mold is arranged on the flywheel lower template and is fixedly connected with the flywheel lower template through a positioning pin, a positioning pin bush and a screw and the drag water cooling injection plate is provided with a water nozzle, a water channel and a sand nozzle. The universal negative type combined model has the advantages of high production efficiency, substantially reduced cost, simple operation and a high qualified rate of products.

Description

Technical field: [0001] The invention belongs to the field of casting moulds, and in particular relates to a general negative combined mould, which is used in the production of diesel engine flywheels with iron moulds covered with sand. Background technique: [0002] According to the existing general sand-covered iron mold production process, the design and manufacture of each flywheel model requires a set of molds to cooperate with a plurality of iron molds and other supporting tooling molds. Since Guangxi Yuchai Machinery Co., Ltd. has hundreds of types of diesel engine flywheels, according to the conventional general-purpose sand-covered iron mold production process, it is necessary to manufacture hundreds of sets of molds and thousands of sets of iron molds. Because each set of iron molds and molds The cost of the flywheel is as high as tens of thousands to hundreds of thousands, which has caused the excessive cost of producing flywheels with the general iron mold sand-c...
