Casting method applied to automobile engine cylinder head

Abstract

The invention belongs to the technical field of production and application of automobile assembly parts, and particularly discloses a casting method applied to an automobile engine cylinder head. Thecasting method comprises the following steps of 1, manufacturing of a wax mould of the engine cylinder head, 2, immersing sizing, 3, casting, 4, machining, 5, grinding, and 6, packaging. The casting method applied to the automobile engine cylinder head has the beneficial effects that the production process of the casting method is reasonable in design, the production time of the automobile enginecylinder head is saved, the finished product rate of the automobile engine cylinder head is high, and the production cost is effectively reduced.

Description

technical field

[0001] The invention belongs to the technical field of production and application of automobile assembly parts, and in particular relates to a casting method applied to a cylinder head of an automobile engine. Background technique

[0002] my country's latest national standard "Terms and Definitions of Vehicles and Trailer Types" (GB / T 3730.1-2001) has the following definitions for vehicles: non-track-bearing vehicles driven by power and having 4 or more wheels, Mainly used for: carrying people and (or) goods; traction vehicles carrying people and (or) goods, special purpose. The cylinder head of the automobile engine is installed on the top of the cylinder block, sealing the cylinder from the upper part and forming the combustion chamber. It is often in contact with high-temperature and high-pressure gas, and bears a large thermal load and mechanical load. The cylinder head of the water-cooled engine is equipped with a cooling water jacket , The cooling wate...

[0013] Below in conjunction with specific embodiment, further illustrate the present invention.

[0014] The casting method applied to the cylinder head of the automobile engine of the present invention comprises the following steps, step 1, making the wax mold of the engine cylinder head, a) wax treatment, first detecting that the wax surface is pure, free of impurities and bubbles, wherein the precipitation dewaxing tank The temperature is 90-98°C, the holding temperature is 60-65°C, and the settling time is 26 hours to 35 hours; b) Injection die head, make sure there is no flash, no hole, no dislocation and no deformation. Among them, the wax mold temperature The temperature is 58-65°C, the molding time is 6-10 seconds, and the temperature of ice water is 6-10°C; c) The product is waxed to make sure that the wax is full, the outline is clear, the characters and teeth are intact, and the surface is not rough. No lines, no air bubbles, no dents and deformations. Among them, t...
