Method for molding iron rod head of gold through vacuum weight casting

Abstract

The invention discloses a method for molding an iron rod head of gold through vacuum weight casting, and the method is used for solving various problems of an atmosphere gravity casting method. The method comprises the steps: enabling a housing die to be positioned and placed in a vacuum furnace, wherein the housing die is provided with a crucible part and a casting part which are communicated with each other, and the vacuum furnace is provided with a rotating shaft; enabling a metal ingot to be placed at the crucible part, and enabling the metal ingot to be melted into metal liquid in a vacuum environment; driving the rotating shaft to enable the vacuum furnace to be inclined towards a side, and enabling the metal liquid to flow into a molded die hole in the casting part under the action of gravity; damaging the housing die so as to obtain a cast part which comprises a cast portion; enabling the cast portion to be separated from the cast part, so as to obtain a plurality of cast parts of the iron rod head of golf.

Description

technical field [0001] The invention relates to a method for casting a golf club head, in particular to a method for vacuum gravity casting a golf iron club head. Background technique [0002] Generally speaking, golf clubs can be divided into three categories: woods, irons and putters. At present, the materials commonly used in iron club heads are mostly stainless steel or carbon steel; while the molding method of golf iron club heads is mainly The precision casting process is mainly based on the atmospheric gravity casting method. [0003] For more details, please refer to figure 1 , which is a wax embryo 9 for forming the required shell mold when implementing the atmospheric gravity casting method. The wax embryo 9 includes a sprue cup embryo 91, and a runner embryo 92 is connected to the bottom of the sprue cup embryo 91. The bottom of the runner blank 92 is connected with several gate blanks 93, and the bottom of each gate blank 93 is connected with a casting blank 94...

AI Technical Summary

Problems solved by technology

[0005] (1) Since the casting materials that can improve the functionality of iron club heads often contain active metals (such as manganese, aluminum, silicon, cobalt, titanium, etc.), when the casting materials are smelted in the atmosphere, the active metals in the casting materials will produce The violent oxidation reaction not only increases the difficulty of smelting casting materials, but also easily reacts with the atmosphere during subsequent casting, resulting in oxidation and cracking, resulting in appearances such as sesame spots and black beans on golf iron head castings after casting Defects, even by reaction gas, form a large number of casting defects such as slag holes or reaction pores on the golf iron head casting; in addition, the severe oxidation reaction will also cause the fluidity of the molten metal in the shell mold to decrease, resulting in insufficient casting In some cases, the molding yield of golf iron head castings is reduced, or cold shut (Cold Shut) problems occur, and gaps are formed in golf iron head castings, affecting the tensile strength of golf iron head castings

[0006] (2) Since the smelting casting is carried out by batching, the addition amount of various alloying elements is calculated according to the alloy to be produced to reasonably match the raw materials, but the reactivity of various alloying elements with oxygen or nitrogen in the atmosphere is not the same , so it is necessary to adjust the order and time of addition for each alloy element of the cast material, so as to increase the difficulty of operation

[0008] (4) If the manpower is used to transport the shell mold to the molten metal furnace, if the operator's arm strength is insufficient, or the sprue cup of the shell mold is not aligned with the pouring angle of the furnace, improper operation of various casting actions, It will cause the molten metal to overflow or splash from the sprue cup, which will also cause the danger of the operator and the loss of the casting

[0009] (5) During the process of transporting the shell mold to the front of the furnace, the shell mold will have a certain degree of temperature drop due to leaving the preheating environment, which will affect the molding and quality of the golf iron head casting; If it can still have a certain high temperature, it is necessary to increase the temperature of the preheating shell mold, which will increase the casting cost relative to the problem of high energy consumption
