Manufacturing method for investment casting ceramic mould shell containing filter of golf head

Abstract

The invention relates to a golf head investing ceramic mould shell that has filter and the technology to make it. The invention consists of many filters, the outside of which is embedded inside the center of the in-runner. The technology is: A, make the head mould. B, make wax mould, inwall of which is a raised bar. C. embed the filter in the raised bar. D, pour molten wax to make wax mould. E, joint the mould sets. F, paint the sets with fireproof painting, adhering sand and dry casting mould set. G, dewax and ceramic then get the ceramic mould shell. The invention can filter injurants in liquid metal such as clinker and oxide; improve the elongation by 15 to 20 percent. The technology is simple and fit to big scale production.

Description

Technical field: [0001] The invention relates to a manufacturing method of a casting ceramic mold shell, in particular to a manufacturing method of a golf club head investment casting precision casting ceramic mold shell containing a filter. Background technique: [0002] Golf is an elegant, casual and fashionable sport, which is developing rapidly all over the world. The equipment used is beautifully manufactured, and the quality standards are strict, and no flaws are allowed on the surface of the castings. Currently, in the golf club head precision casting preparation process, the traditional top pouring casting process is adopted. During the pouring process, harmful substances such as slag and oxides in the liquid metal are more likely to enter the casting, causing defects in the casting and forming a large number of waste products, which not only increases the manufacturing cost, but also seriously reduces the production efficiency. The casting surface is repaired by w...

AI Technical Summary

Problems solved by technology

During the pouring process, harmful substances such as slag and oxides in the liquid metal are more likely to enter the casting, causing defects in the casting and forming a large number of waste products, which not only increases the manufacturing cost, but also seriously reduces the production efficiency

The surface of the casting is repaired by means of welding repair, which reduces the quality of the product and cannot meet the requirements for appearance quality

When the liquid metal is filtered by placing a hat-shaped filter at the sprue cup, the flow rate of the liquid metal at the sprue cup changes greatly, is unstable, and is easy to splash, which may easily cause the filter to float and break through, and it is difficult to achieve the ideal filtering effect.

Moreover, the filtered liquid metal enters the mold through long-distance flow, and the active elements still form secondary oxides, which cannot achieve the purpose of purification

The manufacturing process of the existing ceramic shell is complicated, the yield rate is low, and it is not suitable for large-scale production.
