Technical Field

[0001] This utility model relates to the field of mold testing rod technology, specifically a mold testing rod. Background Technology

[0002] Test mold rods (also known as test mold bars or test mold pins) are commonly used tools in mold manufacturing and inspection. They are mainly used to inspect the size, shape, and surface quality of molds. Test mold rods are mainly used for dimensional inspection and shape verification during the mold manufacturing process to ensure that the accuracy of the mold meets the design requirements. They are widely used in injection molds, stamping molds, casting molds, and other fields to help inspect parameters such as the diameter, depth, and surface finish of the mold.

An outer threaded post is provided on one side of each of the arc-shaped measuring end, the spherical measuring end, and the square measuring end. An outer threaded groove is provided at the other end of the rod body, and the outer threaded groove is adapted to the outer threaded post.

[0007] By adopting the above technical solution, three different measuring ends can be disassembled and replaced, thus making it suitable for different usage scenarios.

[0008] Preferably, the outer threaded post has an inner threaded groove inside, and an inner threaded post is fixedly connected to the other end of the rod body inside the outer threaded groove, wherein the inner threaded groove is adapted to the inner threaded post.

[0009] By adopting the above technical solution, the connection strength can be improved through the connection of two sets of internal and external threads, thereby improving the subsequent use effect.

[0010] Preferably, a retaining ring is provided at the connection between the spherical measuring end and the outer threaded post.

[0011] By adopting the above technical solution, the end face of the rod is prevented from directly contacting the arc surface of the spherical measuring end, thus increasing the effectiveness of use.

[0012] Preferably, a limit ring is provided at the connection between the handle and the rod.

[0013] By adopting the above technical solution, the user's thumb rests on the limiting ring when holding the handle, thereby increasing the stability of the hand.

[0014] Preferably, the outer wall of the handle is provided with anti-slip texture.

[0015] By adopting the above technical solutions, its effectiveness can be enhanced.

[0016] In summary, this application has the following beneficial technical effects: by setting three different end faces for the measuring end, it can be used in different measuring environments, and the connection strength is improved by the internal and external double thread connection, thereby increasing the strength of the test mold rod.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] A test mold rod includes a rod body 1, an arc-shaped measuring end 2, a spherical measuring end 3, and a square measuring end 4. The three different measuring ends can be connected to the rod body 1 respectively, improving the measurement effect of the test mold rod. The rod body 1 is made of high-strength steel and has measuring scales. A handle 5 is fixedly connected to one end of the rod body 1. An outer threaded post 8 is provided on one side of each of the arc-shaped measuring end 2, the spherical measuring end 3, and the square measuring end 4. An outer threaded groove 10 is provided at the other end of the rod body 1. The outer threaded groove 10 is adapted to the outer threaded post 8, allowing the measuring ends to be disassembled and replaced, making it applicable to different measurement environments and increasing the effectiveness of use.

[0027] Furthermore, an inner threaded groove 9 is provided inside the outer threaded post 8, and an inner threaded post 11 is fixedly connected at the other end of the rod body 1 and inside the outer threaded groove 10. The inner threaded groove 9 and the inner threaded post 11 are adapted to each other and are connected by two sets of threads, thereby improving the strength of the connection and increasing the service life of the detachable test mold rod.

[0028] Furthermore, a retaining ring 12 is provided at the connection between the spherical measuring end 3 and the outer threaded post 8. The retaining ring 12 is used to contact the rod body 1 to prevent the end face of the rod body 1 from directly contacting the arc surface of the spherical measuring end 3 and causing damage.

[0029] Furthermore, a limiting ring 6 is provided at the connection between the handle 5 and the rod 1. When holding the handle 5, the thumb presses on the limiting ring 6, thereby improving the gripping effect of the test rod.

[0030] Furthermore, anti-slip texture 7 is provided on the outer wall of the handle 5, which can improve the anti-slip effect of the handheld part of the mold test rod, thereby facilitating subsequent use.

[0031] The implementation principle of this embodiment is as follows: When in use, different measuring ends can be connected to the rod body according to different usage requirements. The inner threaded post is connected to the inner threaded groove, and the outer threaded post is connected to the outer threaded groove, so that the measuring ends can be connected. Then, the user holds the handle and presses his thumb against the limiting ring, so that the hand holding the mold rod is more stable, thereby enabling accurate measurement of the parts on the mold.
