Description

Method for manufacturing golf club head wax mold using soluble wax

technical field

The invention relates to a method for manufacturing a golf club head wax mold using soluble wax, especially a method for manufacturing a wax mold with a special shape, and can greatly reduce the number of sub-modules used, so as to effectively reduce costs and improve wax efficiency. Quality manufacturing method after molding.

Background technique

Today's golf club heads that are suitable for tee shots or long-distance shots have a hollow shell, and in order to present a unique appearance or provide a better hitting effect, the common golf club head has a shape inside and outside the shell The design is also becoming more and more complicated, which causes a lot of inconvenience for the related industry in the manufacture and molding of the club head. Among them:

The known method of manufacturing a golf club head wax mold is mainly to prepare upper and lower molds that can be relatively combined. The internal shape is a combined sub-mould with a corresponding shape. The sub-mould is formed by combining several blocks and is assembled on a base, and the base and the upper and lower molds are assembled and fixed, so that the sub-mould Inside the mold cavity of the upper and lower molds, and form a gap corresponding to the thickness of the shell with the inner wall of the mold cavity, and then use the wax injection machine to inject the wax for precision casting into the gap to form the required golf club head wax Finally, each sub-mold can be sequentially pulled out from the inside of the molded wax mold to complete the molding operation of the wax mold, and then provide casting purposes for the subsequent precision casting of golf club heads.

However, the above-mentioned manufacturing method of the conventional golf club head wax mold still has many disadvantages as described below in actual operation:

1. It is not easy to make wax molds with special shapes: this method is designed to match various shapes of club heads, so that when making wax molds, it is necessary to carefully consider the pulling of each sub-mould when it is taken out after the wax mold is formed. Die angle, and mutual interference between each other, so the sub-mold must be combined by a number of components, and if you want to form a club head with a very special shape, the draft angle and interference and other related issues are more difficult Solved, because there are often situations where drafting cannot be performed, resulting in difficulty in mold design, resulting in the failure of the club head to be manufactured.

2. High manufacturing cost: Since this method must use a sub-mold composed of many blocks, the manufacturing cost is relatively increased, and after the wax model is formed, it also takes time to disassemble a large number of blocks, which wastes excess Therefore, this method is not practical in the manufacture and molding of club head wax molds.

3. The quality of the wax mold after molding is not good: because the sub-mold is composed of several blocks, if there is a slight error in the size of each block, it will easily affect the dimensional precision of the wax mold after molding , thereby reducing the quality of the club head after molding.

4. Cannot be mass-produced: When the shape of the golf club head is too complicated, it is relatively necessary to use more blocks to combine into sub-moulds. However, under the conditions of increased cost and difficult disassembly, it is not suitable for related businesses to do so. Mass production work.
