Description

Method for combining wax patterns of golf club heads

technical field

The present invention relates to a wax model of a golf club head, in particular to a wax model of a golf club head that combines a body wax model with back holes and a back combination to form a club head wax model with a matching combination structure, and the bonding part only corresponds to the body wax The local area of the mold back hole can reduce the trimming length of the wax mold and the wax mold bonding method of the golf club head which can reduce the surface finishing workload of the casting.

Background technique

Please refer to Figure 1, the conventional method of combining wax molds of golf club heads, as described in the invention patent of Taiwan Publication No. 514574 "Manufacturing Method of Golf Iron Club Heads", includes the following steps (1) Two-piece wax mold 81 , 82 molding operation respectively, it is to inject wax in the first mold and the second mold (not shown in the figure), to form two-piece wax mold 81, 82 respectively; (2) wax mold bonding operation is to separate respectively The two-piece wax molds 81, 82 are bonded into one (i.e. form a rod head wax mold 8); , 82 bonded into one surface for dipping to form a sand shell mold, then pour out the wax hot melt, and at the same time form a convex part (not shown in the figure) in the sand shell mold, and in the sand shell mold One side of the sand shell mold forms the casting port (not shown in the figure); (4) the operation of manufacturing the iron head (not shown in the figure) of the sand shell mold is to inject hot molten metal into the sand shell mold, and when the molten metal solidifies, , break the sand shell mold, and take out the one-piece seamless iron club head. Wherein the two-piece wax molds 81 and 82 are a body wax mold 81 and a panel wax mold 82 respectively.

The above-mentioned manufacturing method can be used to manufacture an integrally formed club head (not shown in the figure), and directly form a back cavity 83 on the back of the club head, which is particularly beneficial to manufacture the back cavity 83 into a back with a deep hole shape (undercut). Hole 83. However, the body wax pattern 81 and the panel wax pattern 82 do not form a complete surface, that is, a certain gap 84 is still formed between the two wax patterns 81 and 82 . In order to prevent the wax pattern 8 of the rod head from being stained with slurry, the slurry will seep into the gap 84 at the junction of the two wax patterns 81, 82, resulting in defective castings (not shown in the figure) during casting. Therefore, this must be further repaired. The head wax pattern 8 is located at the junction of the two wax patterns 81, 82, so as to produce castings with a certain quality. However, since the length of the junction of the two wax patterns 81, 82, that is, the formation of the gap 84, is equal to the length of the outer periphery of the panel wax pattern 82, the above-mentioned manufacturing method forms a larger repair length, so that the relative improvement in manufacturing costs and increased man-hours.

Another conventional method for combining wax patterns of golf club heads, as described in the invention patent of Taiwan Announcement No. I232783 "Multi-piece Wax Pattern Bonding Method for Golf Club Heads", includes the following steps: (1), making a first wax mold and a second wax mold, the first wax mold has at least one embedded junction; (2), the first and second wax molds use temperature difference to form an assembly margin; (3), the second wax mold is preliminarily embedded Embedding joints in the first wax pattern; (4) cooling and shrinking the first wax pattern so that the first and second wax patterns can be tightly combined to form a rod head wax pattern. Wherein the first wax model is a body wax model, and the second wax model is a panel wax model.

The above-mentioned manufacturing method can also be used to manufacture an integrally formed club head, and directly form a back cavity with a deep hole shape (undercut) on the back of the club head. In particular, the cooling and shrinkage treatment can further reduce the gap at the joint junction to Improve joint quality. Nevertheless, the above-mentioned manufacturing method still cannot completely eliminate the gap at the junction, therefore, it is still necessary to trim or fill the junction of the club head wax model, thus relatively increasing the manufacturing cost and increasing the processing time. Furthermore, when the two wax patterns are selected from the body wax pattern and the panel wax pattern, the length of the joint junction (i.e. the wax pattern joint repair line) is equal to the length of the outer periphery of the panel wax pattern, so the above-mentioned manufacturing method will still form a relatively large gap. The large trimming length results in relatively high manufacturing cost and increased processing time.

Another method for combining wax models of golf club heads, as described in Taiwan Publication No. I229612 "Manufacturing Method of Golf Club Heads", includes the following steps: (1), manufacturing a body wax model and an accessory wax model , the body wax mold has a first joint portion, and the accessory wax mold has a second joint portion; (2), preliminarily combine the first joint portion of the body wax mold with the second joint portion of the accessory wax mold, and 1. A gap is formed between the two joints; (3) Fill the gap with a volatile high-fluidity solvent, so that the body wax mold and the accessories wax mold can be combined into a rod head wax mold by using their own wax materials (4), soaking the rod head wax mold to form a sand shell mold, and then heating and dewaxing the sand shell mold; (5), using the sand shell mold to cast to make a casting of the rod head . Wherein the accessory wax model selects a panel wax model or a sealing wax model for use.

The above manufacturing method can be used to manufacture integrally formed club heads. However, as shown in FIG. Die 94] is formed, so that produce the disadvantages such as increasing mold manufacturing cost and demoulding difficulty. Based on the above reasons, there is indeed a need for further improvement to the above-mentioned wax pattern bonding methods of various golf club heads.
