AI Technical Summary
In the existing technology, corrugated rollers are large and expensive. Directly inspecting the tooth profile will damage the roller surface and cause it to be scrapped. Therefore, it is impossible to effectively inspect the tooth profile data.
The hollow mold tooling uses an arc surface to match the corrugated roller, and solidifies the plaster inside the tooling body to replicate the tooth shape for inspection, thus avoiding direct operation of the corrugated roller.
It enables non-destructive testing of corrugated roll tooth profile data, avoiding damage to the roll surface and improving testing efficiency and accuracy.

[0022] The utility model provides a kind of to expand mould tool, to make the purpose, technical scheme and effect of the utility model more clear, definite, the following referring to drawing and taking example to the utility model further detailed explanation.It should be understood, the specific embodiment described here is only used to explain the utility model, and is not used to limit the utility model.
[0023] In the description of the utility model, it is necessary to understand that the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more features. In the description of the utility model, unless otherwise stated, the meaning of "multiple" is two or more.
[0024] Please refer to Figures 1 to 6 As shown in the utility model provides a kind of to mould, for the tooth of corrugated roller is carried out tooth profile to mould, wherein, the roll surface of corrugated roller is equipped with several teeth arranged in circumferential mode, tooth extends along the length direction of corrugated roller. To mould includes tooling body 1, the tooling body 1 is hollow structure, at least one end of tooling body 1 is equipped with camber surface 2, camber surface 2 is matched with the outer diameter of corrugated roller, one side of tooling body 1 is equipped with limit strip 3, limit strip 3 is located in the side of camber surface 2, and is used to limit the placement position of tooling body 1.
[0025] When using, camber surface 2 is placed on the corresponding corrugated roller, limit strip 3 is abutted with any tooth to determine the placement position of tooling body 1. Then, gypsum is placed into tooling body 1, and the surface of tooth of corrugated roller is covered with gypsum, after gypsum solidifies, the tooth of corrugated roller can be replicated, and finally gypsum can be knocked from tooling body 1 to check tooth profile data.
[0026] In the above, the material used for moulding can be other materials that solidify from liquid besides gypsum, and the material used for moulding should be determined according to actual use.
[0027] In a preferred embodiment, referring to Figure 1 、 3 、5, the tooling body 1 is a cylindrical structure, at least one side wall of tooling body 1 is a plane 11, and the limit strip 3 is located on the plane 11. Through the above setting, multiple teeth with a certain length can be replicated to ensure that at least two teeth can be checked for tooth profile data after the gypsum is knocked from the tooling body 1.
[0028] Optionally, the tooling body 1 is a quadrangular column or a polygonal column.
