Description

Manufacture of hollow golf club head and composite materials thereof

The present invention relates to the manufacture method of a kind of hollow golf head and composite material hollow bulb, refer in particular to a kind of need not again through penetrate film, mucilage, pouring sand, dry, move back cured, shell, move back sand, soldering ... etc. the hollow ball method for making head of complicated processes, commonly use the disappearance of hollow bulb manufacture process with improvement.In manufacturing process, inlay the scope of attack block composite material hollow bulb of inserting dissimilar metal or non-metallic material in advance, and then enhancement is hit function, is reduced production costs.

General on the market at present common golf head mainly is divided into two kinds of bulbs, one is solid, one is hollow, and the bulb manufacture can be divided into die casting and moulding by casting etc., but before manufacturing, must make the bulb model in order to the bulb moulding in advance, so the manufacturing of mould is divided into metal pattern and pottery shell mould etc. again, and metal pattern is applicable to the material that fusing point is lower, pottery shell mould then is applicable to the higher material of fusing point.Now be summarized as follows:

1. the hollow bulb preparation method of metal pattern system utilizes the chiltern material earlier, mat one mould regards its moulding as the mould heart, and extends one in the metal pattern appropriate location and move back the sand mouth, then die casting or moulding by casting, withdraw from moving back the sand mouth place sand that stagnates in hollow bulb, its breach in addition becomes a complete hollow bulb after the soldering.

2. the hollow bulb preparation method of pottery shell mould claims the demoulding casting again, system makes the cured mould of notes of a hollow bulb opening earlier in order to the demoulding, and annotated the film moulding and the cured type of hollow ball head opening, again this cured type film is returned multiple process through being stained with slurry and pouring sand etc., form a pottery shell shell mould and coat membranous type and the more cured type in the pottery shell mould is dissolved taking-up, and then with pouring metal melt in pottery shell mould, treat that its cooling takes off pottery shell mould and again opening part is in addition become a complete hollow bulb after the soldering with cover plate.

The above-mentioned hollow golf method for making head of commonly using but has following shortcoming to exist:

1. the metal pattern hollow ball head mould heart is that sand is made, after moulding, will move back sand by the sand core mouth, still easy remaining sand in it, make and produce noise when hitting, and sand extracting port soldering in addition again, increase production process and easily have the phenomenon of failure welding to take place, not only lose time, cost and easily cause environmental pollution etc.

2. the hollow bulb of pottery shell mould, its making must be cured through annotating, be stained with slurry, drench sand, dry, take off cured ... etc. complicated processes, during production costs, take a lot of work, and after the demoulding must with a cover plate with the soldering in addition of bulb opening part, very easily cause phenomenons such as failure welding.
