[0034] The principles and characteristics of the utility model are described below in combination with the drawings, and the examples are only used to explain the utility model and are not used to limit the scope of the utility model.

[0035] As Figures 1-3 shown, the utility model provides a kind of middle column pipe wax mold anti-deformation tool, it include: upper die 1 and lower die 2, wherein the length direction of upper die 1 and lower die 2 one end is connected by rotating shaft 3 rotation, so that upper die 1 can be rotated by rotating shaft 3, and then open and close tooling.Specifically, the cavity for placing middle column pipe wax mold 6 is formed in the inner cavity after the buckling of upper die 1 and lower die 2, wherein one half of the cavity is provided in upper die 1 and lower die 2, so that the entire middle column pipe wax mold 6 can be placed between upper die 1 and lower die 2, after a certain time after closing mold, wax mold is completely cooled and removed, which can effectively prevent middle column pipe wax mold 6 from deforming and bending.It can be conceived that the specifications and shapes of the cavity and middle column pipe wax mold 6 are matched, and can be adjusted and customized according to different specifications and shapes of middle column pipe wax mold 6, with strong versatility and adaptability.

[0036] By designing improved middle column pipe wax mold 6 anti-deformation tool, tooling design upper die 1 and lower die 2 are connected by rotating shaft 3, which can ensure that upper die 1 and lower die 2 are tightly matched when closing mold, form complete and accurate cavity to place middle column pipe wax mold 6, and opening and closing operation is more simple and convenient, which saves operation time;Compared with prior art, the pressed middle column pipe wax mold 6 is directly placed in tooling for cooling, which can effectively prevent middle column pipe wax mold 6 from deforming during cooling process, improve runner quality and production efficiency, and can standardize production behavior.

[0037] Specifically, in the embodiment, because the length of middle column pipe wax mold 6 is relatively long, middle column pipe wax mold 6 is arranged along the length direction of upper die 1 and lower die 2, and rotating shaft 3 is arranged parallel to the width direction of upper die 1 and lower die 2 on one side of the length direction of upper die 1 and lower die 2, so that the opening angle of upper die 1 and lower die 2 is larger, and middle column pipe wax mold 6 is easily placed in upper die 1 and lower die 2.

[0038] As Figure 3 shown, the lower mold 2 is connected to the end of the rotating shaft 3 and is also provided with a connecting part 8, and one connecting part 8 is arranged on each side of the end surface, and the lower mold 2 between the two connecting parts 8 is hollowed out. In order to realize the connection between the connecting part 8 and the rotating shaft 3, an opening hole is arranged on the connecting part 8 to match the rotating shaft 3, and the rotating shaft 3 passes through the opening hole to realize the matching with the connecting part 8. By arranging two connecting parts 8 on the end of the lower mold 2 and matching with the rotating shaft 3 through the opening hole, the rotating shaft 3 passes through the opening hole on the connecting part 8, so that the upper mold 1 and the lower mold 2 can be smoothly opened and closed around the rotating shaft 3, and the operation is more flexible.

[0039] As Figure 2 shown, the end of the upper mold 1 connected to the rotating shaft 3 extends out of the connecting convex edge 7 towards the lower mold 2, so that when the upper mold 1 is buckled with the lower mold 2, the connecting convex edge 7 is just located between the two connecting parts 8; in this embodiment, the length of the connecting convex edge 7 is equal to the distance between the two connecting parts 8, and the connecting convex edge 7 can rotate in the area formed between the two connecting parts 8 with the rotating shaft 3. Specifically, the rotating shaft 3 passes through the connecting convex edge 7, and the upper mold 1 is fixedly connected with the rotating shaft 3 through fasteners, so that the upper mold 1 can rotate through the rotating shaft 3 to open and close the tooling, wherein the fasteners can be but not limited to screws.

[0040] The arrangement of the connecting convex edge 7 realizes the connection between the upper mold 1 and the rotating shaft 3, and the connecting convex edge 7 is limited in the area formed between the two connecting parts 8 and rotates with the rotating shaft 3, avoiding the possible shaking or misplacement in the rotating or opening and closing process; the upper mold 1 is fixedly connected with the rotating shaft 3 through fasteners (such as screws), and the connection method is simple and reliable.

[0041] As Figures 1-3 shown, in the preferred scheme, a positioning pin 4 is further arranged on the connecting convex edge 7, the positioning pin 4 is embedded in the hole arranged on the connecting convex edge 7 and is arranged obliquely downward, and specifically, the positioning pin 4 is arranged on the side of the connecting convex edge 7 close to the lower mold 2; it can be conceived that in order to avoid that the lower mold 2 hinders the movement of the positioning pin 4 when the upper mold 1 rotates to open and close, a through groove 9 is arranged on the lower mold 2 in the direction of the axis corresponding to the positioning pin 4, so that the movement of the positioning pin 4 is not hindered. In this embodiment, the lower mold 2 is arranged below the upper mold 1, and the direction close to the lower mold 2 is defined as downward arrangement.

[0042] In this embodiment, the positioning pin 4 limits the opening and closing angle between the upper mold 1 and the lower mold 2, and when the tooling is opened, the positioning pin 4 is arranged in the through groove 9 of the lower mold 2, and also provides additional support and positioning for the opened upper mold 1; through the arrangement of the through groove 9, it is ensured that the positioning pin 4 will not be hindered when the upper mold 1 rotates to open and close.

[0043] The positioning pin 4 limits the opening and closing angle between the upper die 1 and the lower die 2. When the positioning pin 4 moves to abut the inner wall of the through groove 9, the position is the maximum position that the upper die 1 can open and close. It is conceivable that the setting angle of the positioning pin 4 can be adjusted to adjust the opening and closing angle of the tooling, which is not limited here. In the embodiment, the angle between the positioning pin 4 and the horizontal direction is set to 45°, and the positioning pin 4 can ensure a rotation angle of 45°, which meets the needs of daily use.

[0044] By setting the angle between the positioning pin 4 and the horizontal direction to 45°, the opening and closing angle between the upper die 1 and the lower die 2 can be accurately controlled, preventing the upper die 1 from rotating excessively during opening and closing, and avoiding potential safety hazards caused by excessive rotation angle. With the limitation of the positioning pin 4, the upper die 1 can reach the required position faster during opening and closing, further improving the work efficiency.

[0045] As shown in Figures 2-3 In a preferred embodiment, a plurality of first grooves 10 are formed on the upper end surface of the lower die 2 on both sides of the cavity. Correspondingly, a connecting protrusion 11 is provided on the upper die 1 corresponding to the position of the first groove 10. When the upper die 1 and the lower die 2 are engaged, the connecting protrusion 11 is embedded in the first groove 10, preventing the upper die 1 and the lower die 2 from being misaligned during the closing process, improving the fitting accuracy and ensuring the molding quality of the product. In the embodiment, two first grooves 10 are formed on the upper end surface of the lower die 2. Similarly, the connecting protrusion 11 also has two, wherein the upper end surface and the lower end surface of the lower die 2 and the upper die 1 are defined according to the relative height when the upper die 1 is placed on the lower die 2. It is conceivable that the first groove 10 and the connecting protrusion 11 can also be symmetrically formed with respect to the cavity, which is not limited here.

[0046] In addition, in order to reduce the burden of the operator, the upper end surface of the upper die 1 and the lower end surface of the lower die 2 are hollowed out, reducing the overall weight of the tooling and making it easier for the operator to handle and install the mold. On the other hand, it also makes the wall thickness thinner, which is more conducive to cooling the wax mold. It is conceivable that the depth and length of the hollowing should avoid the connection position of the cavity and the upper die 1 and the lower die 2. At the same time, the long edges of the upper die 1 and the lower die 2 are respectively grooved, which facilitates gripping, makes it easy to take and place the tooling, and improves the convenience and efficiency of operation.

[0047] As shown in Figure 1As shown, in the preferred scheme, the upper die 1 is provided with a plurality of handles 5 on the side away from the rotation axis 3 in the length direction, and the upper die 1 is opened and closed by operating the handles 5. A feasible connection mode is to connect the handle 5 and the upper die 1 through a fastener, which can be but is not limited to a screw. The handle 5 can be tightly fixed on the upper die 1 through a threaded structure, so as to ensure that the handle 5 is not easy to loosen or fall off during use. When the handle 5 is damaged or needs to be replaced, the handle 5 can be conveniently disassembled by using the fastener connection, so as to facilitate subsequent maintenance and replacement work.

[0048] Although the embodiments of the utility model have been shown and described above, it can be understood that the above-mentioned embodiments are exemplary and cannot be understood as limiting the utility model, and the ordinary skilled in the art can change, modify, replace and transform the above-mentioned embodiments within the scope of the utility model.
