It should be understood that the specific implementation manners described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0036] Embodiment 1

[0037] Please refer to Figure 1-6 , the technical solution of a resin investment mold positioning tooling for a casting provided in this embodiment is as follows: including

[0038] A mold positioning plate 1, a first positioning component 11 provided on the mold positioning plate 1, and a second positioning component 2 provided on the bottom of the arched mold piece 31 and cooperating with the first positioning component 11;

[0039] Wherein the first positioning component 11 includes a plurality of first positioning members 111, and the plurality of first positioning members 111 are arranged in a rectangular array; the first positioning member 111 includes a guiding area 1111, a positioning area 1112, and a receiving area 1113 which are communicated from top to bottom;

[0040] The second positioning component 2 includes: a positioning plate 21 that cooperates with the guiding area 1111, and a second positioning member 22 that cooperates with the positioning area 1112.

[0041] Preferably, in the first positioning components 11 arranged in a matrix, for the sake of easy understanding, the same distance between every two adjacent first positioning members 111 is called the first distance, and the two pairs of mutually parallel vertical side walls in the horizontally placed mold positioning plate 1 are respectively called the first vertical surface and the second vertical surface, that is Figure 1 The surface where the horizontal line is located is the first vertical surface, and the surface where the vertical line is located is the second vertical surface. The projection point of the second positioning member 22 on the vertical mold piece 31 on the first vertical surface is called the first projection point, and the projection point of the second positioning member 22 on the second vertical surface is called the second projection point; in order to ensure that the second positioning component 2 on the mold piece 31 matches the first positioning component 11 during installation, the distance between any two adjacent first projection points is an integer multiple of the first distance. Similarly, the distance between any two adjacent second projection points is an integer multiple of the first distance. Only in this case, the arrangement position of the second positioning component 2 will match the arrangement position of the first positioning component 11, and each second positioning member 22 on the second positioning component 2 can be inserted into the first positioning member 111.

[0042] Preferably, based on the above position arrangement method, in addition to being suitable for the arched mold piece 31, the mold positioning plate 1 of this design is also suitable for the positioning and splicing of mold pieces 31 such as rectangular, sheet-shaped, and arc-shaped. It is only necessary to set a second positioning component 2 that matches the arrangement method of the first positioning members 111 at the bottom of the corresponding mold piece 31 to achieve positioning and splicing.

[0043] Specifically, the first positioning member 111 penetrates through the mold positioning plate 1. In order to ensure the smoothness of the insertion of the second positioning member 22 into the first positioning member 111, the guiding area 1111 is set as an inverted frustum-shaped hole, and the inner wall of the inverted frustum shape of the guiding area 1111 is the guiding surface. The positioning area 1112 is a cylindrical hole, and the outer diameter of the positioning area 1112 is equal to the bottom diameter of the guiding area 1111; the receiving area 1113 is a circular hole; the outer diameter of the positioning area 1112 is smaller than the outer diameter of the circular hole.

[0044] In actual use, the main function of the storage area 1113 is to accommodate sundries and debris during the positioning and assembly process. Therefore, the structural style of the storage area 1113 is not limited to circular holes only, and storage areas 1113 of other shapes are also within the protection scope of this application.

[0045] Specifically, the second positioning member 22 is in a cylindrical shape matching the guiding area 1111; the main function of the positioning plate 21 is that after the second positioning member 22 is inserted into the first positioning member 111, under the limitation of the positioning plate 21, the lower bottom surface of the mold piece 31 and the lower bottom surface of the positioning plate 21 are in contact with the upper plane of the mold positioning plate 1, and the entire mold piece 31 maintains the same horizontal position. Therefore, the style and size of the positioning plate 21 match the upper top surface of the guiding area 1111, and the style and size of the positioning plate 21 can also be larger than (covering) the upper top surface of the guiding area 1111; to ensure the stability of the positioning connection between the first positioning member 111 and the second positioning member 22, the length of the second positioning member 22 is longer than the sum of the depths of the guiding area 1111 and the positioning area 1112; to prevent the second positioning member 22 from being too long and affecting the horizontality of the mold piece 31 after installation, the length of the second positioning member 22 is less than the thickness of the mold positioning plate 1.

[0046] Specifically, among the second positioning members 22 provided annularly at the bottom of the mold piece 31, at least one of the second positioning members 22 is provided with the positioning plate 21; the positioning plate 21 is provided at the bottom of the arc-shaped side wall of the mold piece 31, the lower bottom surface of the positioning plate 21 is flush with the lower bottom surface of the mold piece 31, and the lower bottom surface of the positioning plate 21 is connected to the second positioning member 22. From a top-down perspective, the connected second positioning member 22 and the positioning plate 21 are in an axisymmetric structure.

[0047] Specifically, the second positioning member 22 and the positioning plate 21 at the end of the bottom surface of the mold piece 31 are subjected to vertical cutting; the cutting surface of the second positioning member 22, the cutting surface of the positioning plate 21, the axis of the second positioning member 22, and the side wall 32 of the mold piece 31 to be spliced are located on the same vertical plane.

[0048] Preferably, under this vertical cutting treatment, as Figure 1 shown, when splicing two adjacent arched mold pieces 31, the vertically cut second positioning members 22 at the ends of the bottom surfaces of the adjacent two mold pieces 31 are inserted into the same first positioning member 111 to realize the fixed splicing of the two mold pieces 31.

[0049] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
