Combining method of wax patterns for fabricating golf club head

Abstract

A combing method of wax patterns for fabricating a golf club head is provided in the present invention. Firstly, a golf club head is disassembled to two or more elements in advance, which are respectively formed into wax patterns. Next, a flange capable of being deformed upon being pressed under an appropriate temperature and a corresponding rabbet structure are predisposed on the two wax patterns, then, the temperature of the flange is raised to make it soften, and then, it is pressed into the rabbet by a flattening tool. By utilizing the softening characteristic of the wax upon being heated, the joint surfaces of the two wax patterns are melted into a single wax pattern. By the method, the two wax patterns are combined together without adding a medium there-between, and thereby forming a joint surface with no gaps.

DETAILED DESCRIPTION OF THE INVENTION

Preferred implementing methods of the present invention are illustrated below through the embodiment with reference to the accompanying drawings.

Firstly, refer to FIG. 1, FIG. 2, and FIGS. 3A to 3D, FIG. 1 is an exploded schematic stereogram of a first wax pattern and a second wax pattern according to an preferred embodiment of the present invention, FIG. 2 is a flow chart of a combining method according to the preferred embodiment of the present invention, and FIGS. 3A to 3D are schematic structural views of the combining method of the present invention. The present invention may be applied for the precise casting of various golf club heads, and the golf club iron head is taken as an example in this embodiment. The present invention is suitable for disassembling the golf club head into at least two wax patterns such as a body wax pattern and a panel wax pattern in advance, and next, the two separate wax patterns are molded respectively, and then, the two separate wax patterns are combined into a single wax pattern. As for the specific steps, firstly, a first wax pattern 10 and a second wax pattern 20 are provided, which are separately fabricated in advance, wherein the first wax pattern 10 has a recess portion 11 for the second wax pattern 20 to be embedded therein; a flange 12 is formed on at least an edge 111 of the recess portion 11, such as the edge 111 of the top surface; and on the other aspect, the second wax pattern 20 has a combining portion 21 with a shape corresponding to that of the recess portion 11, and a rabbet 22 with a shape corresponding to that of the flange 12 is disposed at an opposite position corresponding to the flange 12 (Step S10). Then, the first wax pattern 10 and the second wax pattern 20 are combined correspondingly, so as to embed the combining portion 21 on the second wax pattern 20 into the recess portion 11(Step S20). Finally, the flange 12 made of wax is heated to make the flange soften and thereby having plasticity, wherein the heating method may be indirectly heating by way of the heat radiation, or directly heating by using a heated flattening tool 30 to contact the flange 12, that is, the flange 12 is guided into the rabbet 22, and the heated flattening tool 30 is used to continuously heat the rabbet 22, such that the guided flange 12 is melted into a whole with the rabbet 22 made of the same material of wax, and thus, the wax of the joint surfaces of the first wax pattern 10 and the second wax pattern 20 are mutually melted, so as to form a tight combining state without any gap on the joint surface, and thereby combining into a single wax pattern 40 (Step S30).

The combining portion 21 of the second wax pattern 20 of the present invention further includes all the shapes corresponding to that of the recess portion 11 of the first wax pattern 10, e.g., the steplike slot 13 is disposed in the recess portion 11, so definitely the shape of the combining portion 21 of the second wax pattern 20 includes the shape corresponding to the steplike slot 13.

Furthermore, the shape of the cross-section of the flange 12 in the present invention may be a single shape such as triangle, rectangle, polygon, or arc, or any combination thereof.

The heating temperature of the flattening tool 30 in the present invention is within the range from 15° C. to 85° C. The shape of the flattening tool 30 is determined by a process that is performed depending upon the shape of the cross-section of the joint position between the first wax pattern 10 and the second wax pattern 20. The pre-heating method of the flattening tool 30 is to use an open type heating plate or a close type oven.

Of course, the first wax pattern in the present invention is a body wax pattern and the second wax pattern is a panel wax pattern, or the first wax pattern is a panel wax pattern and the second wax pattern is a body wax pattern

The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
