[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] Figure 1 , 2 The components include support legs 1, uprights 2, support rods 3, crossbars 4, first crossbar 4-1, second crossbar 4-2, third crossbar 4-3, fourth crossbar 4-4, bolts 5, steel forks 6, fork heads 6-1, fork handles 6-2, support limiting plates 6-3, etc.

[0020] like Figure 1 , 2 As shown, this utility model is a casting tool for investment casting, including a hollow column 2, which is supported by a bracket. A support rod 3 that can be raised and lowered is provided in the inner hole of the column 2. A threaded bolt 5 is connected to the side of the column 2 to limit and fix the support rod 3.

[0021] Several parallel horizontal bars 4 are fixed on the support rod 3. The steel fork 6 can be supported on the corresponding horizontal bars 4 so that the mold shell can be supported and fixed to the induction furnace during operation.

[0022] The support frame includes at least three support legs 1 evenly distributed along the circumferential direction on the circumferential surface of the column 2, and the upper ends of the support legs 1 are welded and fixed to the column 2. In actual production practice, the support frame uses four support legs 1 symmetrically distributed to ensure that the support frame can reliably and stably support the ground.

[0023] Furthermore, in order to ensure that the bracket can be reliably and stably supported and fixed, the angle between the bracket leg 1 and the column 2 is an acute angle.

[0024] The side of the column 2 is provided with a radial threaded hole, and the bolt 5 is threadedly connected to the radial threaded hole, and the inner end of the bolt 5 abuts against the support rod 3.

[0025] The steel fork 6 includes a fork head 6-1, which is fixedly connected to a fork handle 6-2. A support limiting plate 6-3 is fixed on the fork handle 6-2. During operation, the support limiting plate 6-3 is supported on the crossbar 4. In actual production practice, the support limiting plate 6-3 is located on the fork handle 6-2 near the end of the fork head 6-1.

[0026] The support limiting plate 6-3 is arc-shaped, and the arc groove of the support limiting plate 6-3 is supported on the crossbar 4. The arc top surface of the support limiting plate 6-3 is welded and fixed to the fork handle 6-2.

[0027] The crossbar 4 includes the first crossbar 4-1, the second crossbar 4-2, the third crossbar 4-3, and the fourth crossbar 4-4.

[0028] The support rod 3 is made of round steel, and the diameter of the support rod 3 matches the inner diameter of the column 2.

[0029] The crossbar 4 is fixed vertically to the support rod 3 to ensure reliable and stable support for the steel fork 6.

[0030] like Figure 1 , 2 As shown, during the casting of the fork shell, one end of the steel fork 6 is placed on the crossbar 4 to support the weight of the mold shell and the steel fork, thus achieving the effect of saving effort and stabilizing the casting. There are four crossbars 4, namely the first crossbar 4-1, the second crossbar 4-2, the third crossbar 4-3, and the fourth crossbar 4-4, which can be selected according to the actual casting situation. In addition, before casting, the height of the support rod 3 can be adjusted by bolt 5, thereby adjusting the height of the crossbar 4. The specific adjustment process is as follows: when bolt 5 is loosened, the support rod 3 can slide freely in the inner hole of the column 2, thereby adjusting the height; when bolt 5 is tightened, bolt 5 fixes the position of the support rod 3 and the column 2.

[0031] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it.
