Description

Technical Field

[0001] This utility model relates to the field of wax mold casting technology, specifically to an auxiliary tooling for bonding wax molds into tree shapes. Background Technology

[0002] The utility model patent with patent number 2023233493432 discloses a wax mold structure for vacuum casting of an integrated pressure relief valve, including a main column at the bottom and multiple support columns at the top of the main column. Multiple pressure relief valve casting wax molds are fixedly mounted on the multiple support columns. The multiple support columns are arranged side by side on the same longitudinal plane, and the bottom of the multiple support columns and the top of the main column are fixedly connected as one unit by a horizontally arranged connecting rod. The multiple pressure relief valve casting wax molds are respectively fixed on both sides of the multiple support columns.

[0003] The pressure relief valve casting wax model is fixed to the welding point of the support column by welding. Multiple casting wax models are assembled into a wax tree by welding. When welding the pressure relief valve casting wax model, one side is welded first, and then the other side is welded. However, existing support bases, such as... Figure 1 As shown, after multiple pressure relief valve casting wax molds are welded onto the support to form a wax mold tree, since the weight of the tree segment is greater than the weight of the main column segment, the operator needs to press down on the main column segment. If not careful, the main column segment will lift up and fall. Utility Model Content

[0004] To address the aforementioned technical problems, this technical solution provides an auxiliary tooling for bonding wax model tree components. The mounting opening at the top of the support is designed as a through hole, and its top can press down on the main bar segment, effectively preventing the main bar segment from tilting and falling; thus effectively solving the above problems.

[0005] This utility model is achieved through the following technical solution: An auxiliary tooling for bonding wax model trees includes a base placed on a table, with a bracket and a support fixed at one end and the middle of the base, respectively; the upper part of the bracket and the support is provided with an installation opening and an installation groove on the same horizontal plane; the main rod of the wax model tree is installed in the installation opening and the installation groove of the bracket and the support for limiting its position.

[0006] Furthermore, the mounting port includes a through hole disposed on the bracket that matches the cross-sectional shape of the main column of the wax model tree; the mounting groove includes a slot disposed on the top of the bracket that matches the cross-sectional shape of the main column of the wax model tree.

[0007] Furthermore, when the cross-section of the main column of the wax model tree is circular, the mounting opening is a circular through hole, and the inner diameter of the through hole is consistent with the outer diameter of the main column of the wax model tree; the mounting groove is an arc-shaped groove, and the diameter of the arc-shaped groove is greater than or equal to the outer diameter of the main column of the wax model tree.

[0008] Furthermore, when the cross-section of the main column of the wax model tree is circular, the mounting opening is a circular through hole, and the inner diameter of the through hole is larger than the outer diameter of the main column of the wax model tree; the mounting groove is an arc-shaped groove, and the diameter of the arc-shaped groove is greater than or equal to the outer diameter of the main column of the wax model tree.

[0009] Furthermore, a locking device is provided between the top of the bracket and the top of the circular through hole, and the locking device penetrates the top of the bracket and acts on the main column of the wax model tree.

[0010] Furthermore, the locking device includes an internally threaded through hole disposed between the top of the bracket and the top of the circular through hole, and a screw is threadedly connected to the internally threaded through hole; when locking, the bottom of the screw rests against the main column of the wax model tree. Beneficial effects

[0011] The auxiliary tooling for bonding wax molds proposed in this utility model has the following advantages compared with the prior art: This technical solution sets the mounting port on the bracket as a through hole, and the top of the bracket can press down on the main rod section, effectively preventing the main rod section from tilting up and falling.

[0012] In this technical solution, the inner diameter of the through hole is consistent with the outer diameter of the main column of the wax model tree. After the main column of the wax model tree is installed in the through hole, there is a certain friction between the main column and the inner wall of the through hole, which can prevent the wax model tree from shifting in the through hole.

[0013] In this technical solution, the inner diameter of the through hole is larger than the outer diameter of the main rod of the wax model tree, which makes it easy to install the main rod of the wax model tree in the through hole. Combined with the locking device, the wax model tree can be limited in the through hole and will not shift or rotate. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Various modifications and improvements to the technical solutions of the present utility model made by those skilled in the art without departing from the design concept of the present utility model should fall within the protection scope of the present utility model. Example 1

[0020] like Figure 2 As shown, an auxiliary tooling for bonding wax model trees includes a base 1 placed on a table. A bracket 2 and a support 3 are fixed to one end and the middle part of the base 1, respectively. The upper part of the bracket 2 and the support 3 are provided with an installation port 21 and an installation groove 31 located on the same horizontal plane. The main rod 51 of the wax model tree 5 is installed in the installation port 21 and the installation groove 31 of the bracket 2 and the support 3 for limiting.

[0021] The mounting port 21 includes a through hole provided on the bracket 2 that matches the cross-sectional shape of the main bar 51 of the wax model tree 5; the mounting groove 31 includes a slot provided on the top of the bracket 3 that matches the cross-sectional shape of the main bar 51 of the wax model tree 5.

[0022] If the main column 51 of the wax model tree 5 has a cross-sectional shape of a square, rhombus, rectangle, or other polygon with sharp angles, then it is only necessary to make the through hole on the bracket 2 and the mounting groove on the bracket 3 to match the shape of the cross-section of the main column 51. Furthermore, the dimensions of the through hole and mounting groove 31 on the mounting opening 21 can be slightly larger than the cross-sectional area of ​​the main column 51, allowing for a gap between them; this facilitates the installation of the main column 51 into the mounting opening 21.

[0023] If the cross-section of the main column 51 in the wax model tree 5 is circular, the mounting opening 21 is a circular through hole, and the inner diameter of the through hole is the same as the outer diameter of the main column 51 in the wax model tree 5; the mounting groove 31 is an arc-shaped groove, and the diameter of the arc-shaped groove is greater than or equal to the outer diameter of the main column 51 in the wax model tree 5.

[0024] This setting allows the main rod 51 of the wax model tree 5 to have a certain frictional force between it and the inner wall of the through hole after it is installed in the through hole. This allows the main rod 51 of the wax model tree 5 to remain stationary in the through hole even when the wax model components on one side are welded and the center of gravity of the left and right sides of the tree is not aligned. Example 2

[0025] Although Example 1 can solve the problems in the background art, the diameter of the through hole on the bracket 2 is the same as the outer diameter of the main rod 51 in the wax model tree 5, which makes it very difficult to install the main rod 51 into the installation port 21.

[0026] To address this problem, the inventors made further improvements based on Embodiment 1. The diameter of the mounting port 21 on the bracket 2 was set to be slightly larger than the outer diameter of the main rod 51. Combined with the locking device 4, this not only solves the installation difficulty but also addresses the problem of the wax model assembly 5 rotating due to instability during welding. The specific solution is as follows: like Figure 3 As shown, when the cross-section of the main column 51 of the wax model tree 5 is circular, the mounting opening 21 is a circular through hole, and the inner diameter of the through hole is greater than the outer diameter of the main column 51 in the wax model tree 5; the mounting groove 31 is an arc-shaped groove, and the diameter of the arc-shaped groove is greater than or equal to the outer diameter of the main column 51 in the wax model tree 5.

[0027] A locking device 4 is provided between the top of the bracket 2 and the top of the circular through hole. The locking device 4 penetrates the top of the bracket 2 and acts on the main rod 51 of the wax model assembly tree 5. Specifically, the locking device 4 includes an internally threaded through hole provided between the top of the bracket 2 and the top of the circular through hole, and a screw is threadedly connected to the internally threaded through hole; for example... Figure 4 As shown, when locked, the bottom of the screw presses against the main rod 51 of the wax model tree 5, thereby limiting the position of the wax model tree 5.
