Embodiment Construction

[0016] The engine front cylinder head casting process of this embodiment includes the following steps: 1. Raw material incoming inspection: check the chemical composition and pinhole degree of the raw material, and move it to the warehouse after passing the inspection to ensure that there is a plastic cover to prevent dust and have a qualified label; 2. , Smelting: Turn raw materials into aluminum liquid, the ratio of new material and returned material is 6:4, check the chemical composition and mechanical properties of the alloy liquid; 3, Die-casting: Die-cast the front cylinder head product, check the surface quality and internal quality of the product, and pass The product is moved to the next station; 4. Finishing: remove the flash, burr, etc. of the product, check the product cleaning condition, and move the qualified product to the next station; 5. Drill the center hole: drill through the local extrusion hole Φ14° , check the diameter of the hole, whether the casting is d...

Abstract

The invention relates to a front cylinder head casting process. The front cylinder head casting process includes the following steps that raw material inspection is conducted, wherein chemical components and the pin hole degree of raw materials are inspected; melting is conducted, wherein the raw materials are molten into liquid aluminum, and the chemical components and the mechanical performance of alloy liquid are inspected; pressure casting is conducted, wherein a front cylinder head blank is formed by the liquid aluminum through pressure casting, and the surface quality and the internal quality of a product are inspected; treatment is conducted, wherein flashes and burrs of the front cylinder head blank are removed; central hole drilling is conducted, wherein a local extruding hole is drilled through, the diameter of the hole is inspected, and whether a casting is damaged or not is inspected; shot blasting is conducted, wherein the product is hung on a hanging frame to be subjected to shot blasting, a finished product is manufactured, and whether the chromatic aberration of the finished product is consistent or not is inspected; and finished product inspection is conducted, wherein whether the finished product conforms to all indexes or not is inspected, the problems that in the prior art, a machining process is large in procedure number and large in workload are solved, and the production efficiency is improved. The raw material utilization rate is high, and the production cost is reduced. The cast finished product front cylinder head casting is environment-friendly and practical, and the labor intensity is greatly lowered.

Description

technical field [0001] The invention belongs to the technical field of casting, and in particular relates to a casting process of a front cylinder head. Background technique [0002] The casting level of the front cylinder head of the engine is one of the important symbols to measure the level of a country's manufacturing industry. The current casting process of the front cylinder head of the fuel engine has the disadvantages of high labor intensity and large consumption of raw materials. Not only are there more casting processes, which affects production capacity, but also the weight of castings is heavy and the scrap rate is high. Contents of the invention [0003] In order to overcome the above-mentioned technical problems existing in the prior art, the object of the present invention is to provide a casting process for the front cylinder head of the engine, which has a simple manufacturing process. [0004] The engine front cylinder head casting process provided by th...
