Therefore, the top of the club head body after forming is stepped through the grinding wheel: the grinding process removes the excess thickness on the body of the club head, so that the manufacturing operation of the club head J has the disadvantages of time-consuming labor and labor. . In addition, the gravity-cast club head body is easy to generate air holes internally. When the club head body is ground, the air holes are easy to appear outside, which increases the inconvenience of subsequent surface treatment. Secondly, due to the technical limitations of gravity casting. ', long open / pedestal can only connect up to eight club head body dies, it is difficult to increase the number of wax molds, so that each gravity casting can achieve = the club body yield rate is only about 18 %, there is a disadvantage of low yield. On the other hand, for gravity casting, the shell mold must be preheated for 1 250^ 1300 C for 50 minutes' and the iron alloy such as stainless steel must be melted to 1750C. The energy consumption is too high, and the yield rate of each gravity casting is low. 'There is a problem that the manufacturing cost is too high, and it is necessary to improve it. SUMMARY OF THE INVENTION The main object of the present invention is to provide an atmospheric centrifugal casting method for a head body of an iron-based alloy golf club 201215467, thereby improving the existing club head body formed by the heavy-duty casting method and then grinding the body. The time-consuming and labor-intensive disadvantages of the subsequent steps. In order to achieve the foregoing object, an atmospheric centrifugal iron manufacturing method for an iron-based alloy golf club head body designed by the present invention comprises the steps of: providing a soil module tree, which mainly comprises a plurality of club head dies Connected to a periphery of a circular pedestal wax mold; immersing and dewaxing the enamel module tree to form a shell mold, which comprises a circular shunt having a runner inside the shell mold The space and the ring array are connected to a plurality of head forming spaces at the periphery of the circular shunt space; the shell mold is placed and positioned in the centrifugal casting machine, and the shell mold is preheated at 950 ° C ~ l ° ° C for 30 minutes ' In the atmospheric environment, the shell mold is driven by a centrifugal machine to rotate at a speed of 300 to 500 rpm, and smelting to 165 (TC ~ 1 7001 molten iron-based alloy material is poured into the shell mold through the runner, and rotated by the shell mold. The centrifugal action causes the iron-based alloy raw material to be filled inside the shell mold, and the iron-based alloy raw material to be poured into the shell mold is cooled and solidified, and then taken out; and • the shell mold is taken out to take out the blank embryo, and the head body is separated from the blank embryo. The primordial 'the iron-alloy golf ball The present invention is designed by the above-mentioned atmospheric centrifugal casting method, and the features thereof include at least: 1. The invention is formed by atmospheric centrifugation, and the splitting space of the connected washing lane is circular, and the head forming space loop It is listed on the periphery of the diverting space. In this way, the molten iron-based alloy enhances its fluidity by centrifugation, and indeed fills each head forming space so that the top of the formed club head body can reach 〇. 6±0 The size of 05mm is close to the predetermined thin top design. 5 201215467 2. As mentioned above, because the size of the top of the formed club head can reach the size of the dome, it is no longer necessary to carry out the top of the club body. A large number of grinding processes and reduce the formation of surface pores. 3. In the atmospheric centrifugal casting step of the shell mold, the shell mold only needs to be preheated to 950 ° C ~ 100 (Tc, 30 八 in M w, L JO minutes And iron alloys such as stainless steel must be heated and melted to 165rc~17〇(rc, compared to the conventional gravity casting method to preheat the shell mold to 125 (rc~13〇〇t, 5〇 minutes and as Stainless steel heating The method of processing 175 (rc), the invention has the excellent performance of energy saving w. 4. The wax module tree used in the present invention is a structure in which a plurality of club head body wax patterns are connected by a circular base. Atmospheric centrifugal casting method, it is possible to connect more than eight club head body loams on the periphery of the circular base, which is more than the number of the bulb body of the wax module tree of the conventional gravity casting method, so the invention is implemented The yield is much higher than the yield of gravity casting. [Embodiment] As shown in FIG. 1 is a preferred embodiment of the atmospheric centrifugal casting method for revealing the iron-based alloy crucible head body of the present invention, and its implementation The steps mainly include: providing a wax module tree, as shown in FIG. 2' FIG. 3, the wax module tree is mainly connected to a plurality of head wax molds 12 in a circular base wax mold 1 The outer base of the circular base wax mold has a sprue portion 13 on the side of the crucible, and a plurality of radially arranged connecting arms u are formed on the periphery, and a head wax mold 12 is respectively provided thereon; Wax module tree is dipped and dewaxed to form a shell mold, so that the shell The inside of the circular base is dewaxed to produce a round 201215467 split flow space with a sprue, which is formed into a head/space by dewaxing at each of the head wax molds, and the head forming space loops are respectively formed. Connected to the outer shape of the circular shunting space f, the shell mold is placed and positioned at the rotating end of the centrifugal casting machine, and the shell mold is rotated by the centrifugal casting machine under the atmospheric environment, wherein the best turning is 300 to 500 per minute. The molten iron-based alloy material is poured into the shell mold through the 2 = channel, and the iron-based alloy material is filled in the shell mold by the centrifugal action of the shell mold rotation, and the iron-based alloy material to be poured into the shell mold is rotated. After cooling and solidifying, the shell mold was taken out and passed through 950. 〇1 00 0 It is preheated for 3 〇 minutes, the metallurgical melting temperature of the iron-based alloy is 165 (rc~170 (rc, re-filled into the shell mold; to: destroy the shell mold to remove the embryo, and separate from the embryo) The head metal body of each head body obtains the iron-based alloy golf club head body of the present invention. As just mentioned, the iron-based alloy golf club head body is cast by atmospheric centrifugation and then combined with the shunt of the communicating runner. The space is circular, and the head forming space is arranged around the periphery of the splitting space. Thus, the molten iron Z alloy is lifted by centrifugal action to enhance its fluidity, and is indeed filled in each of the heads to form two, so that after forming The top of the club head body can reach a size of 〇6±0.05_, which is close to the predetermined thin top design, no need to carry out a large amount of grinding on the top and reduce the formation of surface pores. After that, the head body of each head body Then, it can be fixed with the hitting panel and the subsequent surface beautification processing, and then connected to the rod body to obtain the fairway wood pole. On the other hand, the wax module tree used in the present invention adopts a circular base peripheral connection. Constructing a plurality of head wax patterns Because of the atmospheric centrifugal casting method, it is possible to connect more than eight (such as 彳6, 24, etc.) wax heads on the periphery of the circular base, whereby the embryos after each centrifugal casting are used. The yield of the formed club body is much higher than that of gravity casting. For example, 24 club heads can be formed once per 201215467, and the yield is about 25%. Each time, 16 balls can be formed. For example, the head body has a yield of about 28% ··. etc. Further, when the present invention performs the atmospheric centrifugal casting step of the shell mold, the shell mold only needs to be preheated to 950.
