[0031] As shown in Figures 1 to 3 A shell wax mold structure 10, including a die head 100 and a support assembly 200, the die head 100 is provided with a flow divider 300 on one end, and the diameter of the die head 100 gradually decreases in the direction close to the flow divider 300, the support assembly 200 includes a main column 210, an end block 220 and a plurality of support columns 230, the two ends of the main column 210 are connected with the flow divider 300 and the end block 220 respectively, each support column 230 is divided into two groups, the two groups of support columns 230 are located on the two sides of the main column 210 respectively, and the two ends of each support column 230 are connected with the flow divider 300 and the end block 220 respectively, the main column 210 and each support column 230 are used for connecting a plurality of wax parts 20 independently or jointly.
[0032] It should be noted that the flow distribution block 300 is a transfer structure between the mold head 100 and the main column 210 / each column 230. Through the flow distribution block 300, when the molten metal is poured subsequently, it can be ensured that the molten metal can flow from the position of the mold head 100 to the position of the flow distribution block 300, and then quickly flow into the position of the main column 210 and each column 230. It should be noted that the diameter of the mold head 100 gradually decreases towards the flow distribution block 300, which can ensure that the subsequent molten metal flow maintains sufficient injection pressure, so as to finally flow into the position of each wax piece 20 through the main column 210 / each column 230. It should be noted that the outer side wall of the main column 210 and the outer side wall of each column 230 together form the area where the wax piece 20 is installed. The number of columns 230 is set to be even, and for the purpose of description, four columns 230 are taken as a specific embodiment in the present application. In one embodiment, the wax piece 20 is individually installed on the main column 210 or the column 230. In another embodiment, the wax piece 20 is installed on two columns 230. Further, in another embodiment, the wax piece 20 can also be installed on the main column 210 and at least one column 230. In this way, according to the specific size of the wax piece 20, the wax piece 20 can be individually installed on the main column 210 or the column 230, or installed on the main column 210 and one column 230, or installed on the main column 210 and two columns 230, or installed on the main column 210 and three columns 230, or installed on the main column 210 and four columns 230. Therefore, the shell-making wax mold structure 10 of the present application is suitable for installing wax pieces 20 of different sizes, and is not limited to a single size of wax piece 20, and has good versatility; and a plurality of wax pieces 20 can be installed at the same time, and each wax piece 20 can form a casting, so that a plurality of castings can be formed on the shell-making wax mold structure 10, which can effectively improve the efficiency of the lost wax casting compared with the existing shell-making and casting of a single wax piece 20.
[0033] In an embodiment, the die 100, the flow dividing block 300, the main column 210, the end block 220 and the columns 230 are integrally formed. For example, the shell-making wax mold structure 10 is integrally formed of wax, so that the shell-making wax mold structure 10 can be mass produced by using a mold injection process. After the shell-making wax mold structure 10 is produced, the wax pieces 20 are bonded to the outer side walls of the main column 210 and the columns 230, and the shell-making wax mold structure 10 and the plurality of wax pieces 20 are then shell-made. The wax of the shell-making wax mold structure 10 and the plurality of wax pieces 20 is then melted and removed, so that a shell-shaped structure formed by the shell-making wax mold structure 10 and the plurality of wax pieces 20 is obtained. Molten metal is then poured into the shell-shaped structure, so that a casting is formed at each position of the wax pieces 20. The shell-making wax mold structure 10 is located at a waste seat, and each casting is connected to the waste seat. The castings are then cut from the waste seat by a cutting process, and the waste seat can be reused by being melted and reused, so that waste is avoided. In this way, the plurality of wax pieces 20 are mounted on the main column 210 and the columns 230, so that a plurality of castings can be produced at the same time, and the efficiency of the lost wax casting process is improved.
[0034] As shown in FIG. 1, in an embodiment, the main column 210 is integrally formed with the end block 220. Figures 1 to 3 As shown in FIG. 1, in an embodiment, the main column 210 is integrally formed with the end block 220.
[0035] It should be noted that the main column 210 is integrally formed with the end block 220, so that the main column 210 and the end block 220 can be integrally formed by using a mold injection process, and the main column 210 and the end block 220 can be integrally formed of wax.
[0036] As shown in FIG. 1, in an embodiment, the main column 210 is integrally formed with the end block 220. Figure 1 As shown in FIG. 1, in an embodiment, the main column 210 is integrally formed with the end block 220.
[0037] It should be noted that the main column 210 is integrally formed with the end block 220, so that the main column 210 and the end block 220 can be integrally formed by using a mold injection process, and the main column 210 and the end block 220 can be integrally formed of wax.
[0038] As shown in FIG. 1, in an embodiment, the main column 210 is integrally formed with the end block 220. Figures 1 to 3 As shown in FIG. 1, in an embodiment, the main column 210 is integrally formed with the end block 220.
[0039] It should be noted that the main column 210 is integrally formed with the end block 220, so that the main column 210 and the end block 220 can be integrally formed by using a mold injection process, and the main column 210 and the end block 220 can be integrally formed of wax.
[0040] As shown in FIG. 1, in an embodiment, a height-limiting protrusion 260 is arranged on the outer side wall of the joint position of the shunt block 300 and the support column 230. Figures 1 to 3
[0041] It should be noted that the height-limiting protrusion 260 is used to warn the operator not to pass the height-limiting protrusion 260 when installing the wax piece 20 on the main column 210 / support column 230. Therefore, it can be avoided that the worker mistakenly installs the wax piece 20 on the position of the shunt block 300.
[0042] As shown in FIG. 1, in an embodiment, a height-limiting protrusion 260 is arranged on the outer side wall of the joint position of the shunt block 300 and the support column 230. Figures 1 to 3
[0043] It should be noted that after the wax piece 20 is installed on the main column 210 / support column 230, the shell-making wax mold structure 10 needs to be put into the refractory slurry together with the plurality of wax pieces 20 for dipping or spraying to make a shell. Therefore, by arranging the limiting ring 400 on the top of the mold head 100, it is used to mark that the refractory material cannot pass this position, so as to avoid affecting the subsequent wax melting process. In an embodiment, the outer diameter of the limiting ring 400 is greater than the maximum outer diameter of the mold head 100. In this way, the refractory material can be effectively prevented from passing the limiting ring 400, so that the shell-making wax mold structure 10 of the present application is convenient to use.
[0044] As shown in FIG. 1, in an embodiment, a height-limiting protrusion 260 is arranged on the outer side wall of the joint position of the shunt block 300 and the support column 230. Figures 1 to 3
[0045] It should be noted that since the distance between the support column 230 located at the most side and the mold head 100 is far, in order to avoid that the temperature of the metal flowing into the support column 230 located at the most side drops too fast in the subsequent pouring of the molten metal, the edge flow bar 500 is arranged between the mold head 100 and the shunt block 300. The edge flow bar 500 is located at the top of the shunt block 300 close to the support column 230 located at the most side. In an embodiment, two edge flow bars 500 are arranged, and the two edge flow bars 500 are respectively located at the two sides of the mold head 100. In this way, the two edge flow bars 500 correspond to the two support columns 230 located at the most side respectively.

Among them, the installation / fixed / setting in the utility model is understood as including but not limited to the locking and fixing by using screw / screw, welding unless otherwise defined. It should be pointed out that for ordinary skilled person in the art, without departing from the concept of the utility model, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
