[Technical field of the invention] The present invention relates to a wax mold structure of a golf club head, in particular, the parallel connection by a bracket One of the connecting blocks and a separating block are extracted, so that the formed mold mold structure can be drawn in parallel and the wax mold structure of the inner circumference of the opening of the die can be prevented from being inclined. [Prior Art] The die mold structure of the conventional golf club head, as shown in Figs. 1 and 1A, the wax mold mainly includes a plurality of outer molds U, 12, and a plurality of molds (inner molds) 21, 22 and a bracket 30, the outer molds η, 12 correspondingly recessed to form a set of mold holes 111, 121 and the die 112, 122 of the preset shape, respectively, to accommodate the mold cores 21, 22 and the bracket 30, The holder 30 suspends the mold cores 21 and 22 in the mold holes ill and 121, so that when the mold holes 121 are filled with the wax liquid and cooled and solidified, one of the predetermined head shapes can be formed. , wax mold 40, for subsequent use of precision casting process to manufacture golf club heads. The design of the above wax mold is generally in a parallel mold opening manner, that is, the joint faces 112, 122 and the combined faces 23 of the mold cores 21, 22 are simultaneously parallel to the horizontal plane of the outer casing 11, 11 so that it is convenient The combined mold cores 21, 22 and the holder 30 are smoothly extracted from the mold 40. However, the parallel mold opening design neglects that the front surface 41 of the mold 40 (ie, the striking surface of the rod) has an inclination angle of 0 with the vertical plane of the outer molds 11, 12, so that the brackets 30 disposed in parallel are practically impossible. The opening 42 of the core 40 is formed into a vertical inner circumference, so that the inner circumference of the opening of the head (not shown) obtained by subsequent precision casting is also inclined. In this way, when the club head is combined with the striking panel, the modified replacement will form an excessive gap between the two on July 20, 1999, and thus affect the soldering product f (such as soldering depth, solder gap, solder and substrate). The degree of integration, etc.]. In particular, when high-energy welding (laser welding, plasma arc welding) is used in combination, the weld bead deviation caused by the above-mentioned gap will be more serious due to the concentration of heat energy and the narrow bead width. For the above reasons, such club heads can only use artificial argon welding (TIG) and a large number of re-welding combined with the striking panel to overcome the problem that the inner circumference of the opening cannot be in close contact with the outer periphery of the striking panel. For another conventional die mold construction, please refer to the new patent of the “Clapstick Mould for Golf Club Head”, which was previously approved by the applicant and approved by the Republic of China, No. 563599, as shown in Figures 2 and 2A. The mold also includes a plurality of outer molds 11, 12, a plurality of mold cores 21, 22, and a holder 3, but the wax mold is further subjected to a normal mold opening method. That is, the joint faces 112, 122 of the outer mold 11 and the combined faces 23 of the mold cores 21, 22 form a proper compensating inclination angle 0 with respect to the horizontal plane of the outer mold 11. The compensating inclination angle 0 is equal to the angle 0 formed by the vertical surface of the front surface 41 of the wax mold 40 and the outer mold 11, that is, the impact angle. Therefore, the inner circumference of the opening 42 of the mold 40 can be formed at a right angle with respect to the front surface 41 of the wax mold 40 without affecting the extraction of the mold core 21, 22 and without adding additional processing to enhance the wax mold opening. The quality of casting and welding of 42 and subsequent club heads. However, the above-mentioned normal mold opening method also has the following technical problems: when the compensating inclination angle 0 is greater than 15°, the difference in the volume ratio of the mold cores 21 and 22 is increased, so that the extraction of the mold cores 21 and 22 may be increased. Difficulty. Further, the holder 30 is generally joined to the mold core 21' 22 by a joint structure such as a nipple (not shown), and the mold cores 21 and 22 are suspended in the mold holes m 1333866 and 121. However, such an oblique bonding method is liable to cause looseness, lowering the suspension stability of the mold cores 21, 22, and thereby affecting the wall thickness accuracy of the wax mold. For the above reasons, it is indeed necessary to further improve. _ Eight sentences with the wax mold structure of the golf club head. In view of the above, the present invention improves the above disadvantages, wherein a wax mold mold adopts a horizontal mold opening method, and a joint block and a separation block ' are connected by a bracket, and the joint block and the separation block form a horizontal plane with respect to the outer mold. Appropriate compensatory tilt angle. Thus, after a wax mold is manufactured using a wax mold, the inner peripheral edge of the opening of the wax mold can form a right angle with respect to the front surface of the wax mold. Thereby, the present invention can improve the release quality of the wax mold and the yield of subsequent casting and welding. SUMMARY OF THE INVENTION The main object of the present invention is to provide a wax mold structure for a golf club head, wherein a bracket is coupled to a connecting block and a separating block, and the opening direction of the bracket is parallel to the horizontal plane of the outer mold, the connecting The combination of the block and the separation block forms a suitable compensating inclination angle with respect to the horizontal plane of the outer mold, thereby preventing the inner circumference of the opening of the wax mold from being inclined, so that the invention has the advantages of improving the wax mold release product and the prayer and welding yield. efficacy.
