Golf club head multi-piece wax mould connecting method

Abstract

The present invention relates to a several wax matrixes combination method of golf club head. It includes the following steps: respectively making a first wax matrix and a second wax matrix, said first wax material at least has an embedding combination portion, said first and second wax matrixes utilize temperature difference to form assembling tolerance, inserting said second wax matrix into the embedding combination portion of the first wax matrix, making cooling and shrinkage treatment so as to make the first and second wax matrixes be tightly combined together and formed into a club head wax matrix.

Description

technical field [0001] The present invention relates to a multi-piece wax mold joining method of a golf club head, in particular to a joining method in which two wax molds use heat expansion and contraction to produce interference fit to simplify combination and form a tight assembly. Background technique [0002] Please refer to Figure 1 to Figure 3 for the manufacturing method of the existing golf club head, which discloses the invention patent of the manufacturing method of the golf iron club head of China Taiwan Patent No. 514574, and the method includes the following steps: [0003] (1), the two-piece wax molds 10, 20 are formed separately, as shown in Figure 1 and Figure 1a, it injects wax liquid respectively in the first mold and the second mold (not shown), after making it open Form two-piece wax patterns 10,20 respectively, such as a body wax pattern 10 and a panel wax pattern 20; Bonding operation, and two independent wax molds 10,20 are bonded into one; (3), dipp...

Problems solved by technology

However, as shown in Figures 1a, 2a and 3a, when the gap filling is not dense, a gap a will be generated between the two wax patterns 10, 20, and the gap a will cause the slurry to penetrate into the gap when the slurry is soaked.

As a result, after dewaxing, a burr b will be formed in the obtained sand shell mold 30, and after casting, the burr b will cause the club head 40 to form a gap c, which in turn will reduce the strength of the club head 40. Casting product yield

On the other hand, when too much wax liquid is used on the surface of the junction, although the solidified wax liquid can fill the gap a, it will instead cause irregular protrusions (not shown) on the surface of the junction, which will lead to subsequent fabrication. The club head 40 must be more complicated surface grinding

In particular, if the irregular protrusions are formed at the junction of the back pocket 41 of the club head 40, it is difficult for the workpiece to enter the back pocket 41, so the surface grinding process in the back pocket 41 will become extremely difficult. As a result, the processing cost is greatly increased and the process time is prolonged
