Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the obtained embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0050] See also Figure 1-12 A thermal insulation material bonding shear test piece molding tool comprises a bottom plate, a shell test piece, a partition, a side pressure plate, a thermal insulation layer, a test piece pressure plate and a cover plate.

[0051] See also Figure 2 and 12 A lower cavity 101, an upper cavity 102, a baffle 103, a baffle 104, a baffle 105 and a baffle 106 are provided on the bottom plate. The height difference between the molding surface 102-2 of the upper cavity 102 and the molding surface 101-2 of the lower cavity 101 is the sum of the heights of the insulation layer 4 and the shell specimen 32, and the length is consistent with the length of the shell specimen 31. By utilizing the above structure, it is ensured that the two shell specimens are parallel to each other, the thickness of the insulation layer 4 meets the standard requirements, and the shell specimen and the insulation layer 4 are not misaligned along the direction of the test loading force during the manufacturing process.

[0052] See also Figure 2 and 3 The baffle 103 on the bottom plate 1 is fitted with the edges of the upper cavity 102 and the lower cavity 101. The baffle 104 is in an "L" shape, and the bottom is connected to the upper cavity 102 and the lower cavity 101. The bottom height is less than the height of the mold surface 101-2 of the lower cavity 101. There is a 10mm gap between the upper half and the edges of the upper cavity 102 and the lower cavity 101. The screw hole 109 is located in the upper half of the baffle 104. The side pressure plate 7 with a thickness of 6mm is placed in the gap between the upper half of the baffle 106 and the upper cavity 102 and the lower cavity 101. The top is flush with the top of the baffle 106. The side pressure plate 7 is fixed by M8×25 bolts through the screw holes 109 so that its edge is flush with the edge of the upper cavity 102 and the lower cavity 101. The above structure ensures that the insulation layer 4 is effectively pressurized in the direction perpendicular to the test loading force during the manufacturing process.

[0053] See also Figure 2 and 6 The bottom plate 1 is provided with a screw hole 107, the cover plate 2 is rectangular, and the cover plate 2 is provided with a round hole 201. The screw hole 107 is equipped with a bolt of size M6×16. The diameter of the round hole 201 is 3mm larger than the M6×16 bolt. The position of the round hole 201 corresponds to the position of the screw hole 107. The relative position of the cover plate 2 and the bottom plate 1 is fixed by the M6×16 bolt installed on the round hole 201 and the screw hole 107. With the above structure, when the shear test piece is prepared by a hot press, the effective pressure on the bonding surface can be guaranteed, which improves the accuracy of the data.

[0054] See also Figures 7 to 12 , the insulation layer 4 is a cube, composed of a double layer of insulation material, and its length and width are consistent with the width of the shell specimen, and the thickness of the insulation layer 4 is 4mm. The partition 5 is installed on the bottom plate 1, and fits with the mold surface 102-2 of the upper cavity 102 and the mold surface 101-2 of the lower cavity 101, and separates the shell specimen and the insulation layer 4 during the assembly of the test specimen. The specimen pressing plate 6 is a rectangular parallelepiped, with a width consistent with the width of the shell specimen 31, a length that is the difference between the length of the shell specimen 31 and the length of the insulation layer 4, and a height that is the sum of the height of the shell specimen 32 and the height of the insulation layer 4. Through the above structure, it can be ensured that the insulation layer is fixed during the hot pressing process to prevent the shear specimens from sticking together due to overflowing glue, and at the same time ensure that the center lines of the two shell specimens in the direction of the loading force coincide, thereby ensuring the accuracy of the test data.

[0055] See also Fig.11 The shear test piece is made by sandwiching the heat insulation layer 4 between two shell test pieces, and the edge of the heat insulation layer 4 is flush with the edges of the two shell test pieces. Shell test piece 31 and shell test piece 32 have the same structure.

[0056] The process of making shear specimens can be found in Fig.12: Place the shell test piece 31 coated with adhesive on the surface in the lower cavity 101 so that the shell test piece 31 fits the mold surface 101-2 of the lower cavity, place the double-layer insulation layer 4 coated with adhesive on the shell test piece 31, place partitions 5 on both sides of the shell test piece 31, place the test piece pressing plate 6 between the insulation layer 4 and the baffle 105 of the bottom plate 1, place the shell test piece 32 coated with adhesive in the upper cavity 102 so that it is located between the two partitions 5 and the test piece pressing plate 6 and the baffle 106 of the bottom plate 1, and the installation of the remaining four shear test pieces is similar to the above process. After the shear test piece is installed, place the side pressing plate 7 in the gap between the upper half of the baffle 106 and the upper cavity 102 and the lower cavity 101, and use M8×25 bolts through the screw holes 109 to tighten and fix the side pressing plate 7.

[0057] The mold of the present invention has the characteristics of compact structure, simple construction, and convenient assembly and disassembly. The shell test piece is positioned by the bottom plate, the side pressure plate and the partition plate to ensure that the center lines of the two shell test pieces and the insulation layer in the direction of the loading force are consistent during the preparation of the test piece; the insulation layer is fixed by the joint action of the partition plate and the test piece pressure plate to prevent the loss of the insulation material rubber and ensure that the length and width errors of the insulation material bonding surface are reduced; the cover plate and the bottom plate are positioned by the positioning holes, and the bonding interface is pressurized through the cover plate by bolts or a hot press, so that the preparation of the insulation material interface bonding shear test specimen is more standardized and the test data is more accurate.
