[0035] The following will specifically describe the preferred embodiments of the present invention in conjunction with the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present invention to explain the principles of the present invention, rather than to limit the scope of the present invention.

[0036] A wire resin forming mold for bond strength detection in this embodiment relates to the technical field of wire resin strength detection. Only by setting one wire 420, multiple test models can be formed at one time, and the preparation efficiency of the test models is high. The wire drawing assembly 300 can maintain the straightness of the wire 420, avoid excessive connection between the wire 420 and the module 410, and interfere with the accuracy of the detection.

[0037] Please refer to Figures 1 to 7 , a wire resin forming mold for bond strength detection in this embodiment includes an inner mold 100, an outer mold 200 and a wire drawing assembly 300. The inner mold 100 includes a left half mold 110 and a right half mold 120 arranged oppositely. A plurality of forming grooves 130 are opened on the opposite sides of the left half mold 110 and the right half mold 120. The side parts of the left half mold 110 and the right half mold 120 are spliced to form the inner mold 100. The forming grooves 130 on the left half mold 110 and the forming grooves 130 on the right half mold 120 are spliced one by one to form a forming hole 140 for pouring resin. The forming hole 140 can shape the resin to form the module 410. Just separate the left half mold 110 and the right half mold 120, and the formed module 410 can be taken out to achieve non-destructive and rapid demolding.

[0038] The outer mold 200 includes an outer frame 210 and a bottom plate 220. The outer frame 210 is sleeved on the inner mold 100. The outer frame 210 can fix the left half mold 110 and the right half mold 120 together to assemble and form the inner mold 100. The inner walls of the outer frame 210 are respectively abutted against the side walls of the left half mold 110 and the right half mold 120, which can not only fix the two half molds to prevent them from separating, but also position the two half molds so that different forming grooves 130 are accurately aligned, avoiding misalignment during forming and causing deformation of the forming holes 140, and ensuring that the shape of the module 410 conforms to the corresponding specifications.

[0039] The wire drawing assembly 300 is connected to the outer mold 200. The wire drawing assembly 300 can straighten the steel wire 420 passing through each forming hole 140, ensure the straightness of the steel wire 420, make the steel wire 420 always perpendicular to the module 410, and avoid bending of the steel wire 420 relative to the module 410, which changes the contact length between the steel wire 420 and the module 410 and affects the accuracy of the detection result of the bonding degree.

[0040] In some embodiments, please refer to Figures 1 to 3 , a demolding layer 150 is provided on the left half mold 110 and the right half mold 120. The demolding layer 150 is provided on the docking surface of the left half mold 110 and the right half mold 120 and in the forming groove 130. The setting of the demolding layer 150 enables the formed resin model to be more easily taken out of the mold, reduces the resistance during demolding, and can improve the forming efficiency of the module 410.

[0041] In addition, the demolding layer 150 can effectively reduce the wear of the resin on the surface of the mold, extend the service life of the mold, and ensure the quality and consistency of the module 410. The demolding layer 150 can be a polytetrafluoroethylene layer, a silicone coating, a fluororubber or a polyimide layer. The demolding layer 150 has an extremely low friction coefficient and excellent chemical resistance, and can maintain stable performance within a wide temperature range.

[0042] In some embodiments, please refer to Figures 2 to 4 , a plurality of wire threading grooves 160 are further provided on the opposite sides of the left half mold 110 and the right half mold 120. The wire threading grooves 160 on the left half mold 110 and the right half mold 120 are spliced in one-to-one correspondence to form a wire threading hole 170 for threading the steel wire 420. The end parts of each wire threading hole 170 are respectively communicated with the forming hole 140. The wire threading holes 170 cooperate with each other to form a traveling channel for the steel wire 420, which can correct the state of the steel wire 420 and make the steel wire 420 always keep a straight setting.

[0043] In addition, the position of the wire threading hole 170 relative to the inner mold 100 is set relatively centered, such that the wire threading hole 170 intersects with the forming hole 140 and is located in the middle of the forming hole 140. The wire threading hole 170 enables the steel wire 420 to be accurately positioned and fixed during the forming process, preventing the steel wire 420 from moving or deviating during the resin casting process. This helps to ensure the accurate position of the steel wire 420 in the resin model, thereby improving the accuracy of the adhesion detection.

[0044] It should be specifically noted that the wire threading hole 170 ensures that the position of the steel wire 420 is consistent in each forming process and the resin is evenly poured, thereby ensuring the consistency of each formed model. When performing adhesion detection on multiple approximate models, the average value of the results is closer to the true value, guaranteeing the accuracy and repeatability of the adhesion detection results.

[0045] In some embodiments, please refer to Figure 2 , a plurality of demolding holes 221 are provided on the bottom plate 220. One end of the demolding hole 221 is communicated with the inner mold 100. The demolding hole 221 can be used to insert a ejector pin or an air nozzle to provide additional ejecting force or air pressure during demolding, making it easier for the formed resin model to be removed from the mold. The setting of the demolding hole 221 simplifies the demolding operation and reduces the possible damage to the model during the demolding process.

[0046] By introducing air through the demolding hole 221 during demolding, the adhesion force between the resin model and the mold can be reduced, the demolding resistance can be decreased, and the integrity and surface quality of the formed model can be improved.

[0047] The demolding hole 221 is arranged between two forming holes 140, and the demolding hole 221 and the forming hole 140 are spaced from each other, which can avoid interference between the forming hole 140 and the demolding hole 221 and ensure the forming quality of the resin by the forming hole 140.

[0048] As a further implementation manner, the cross-section of the forming hole 140 is triangular, circular or rectangular. By adopting the above shapes for the forming hole 140, the surface of the formed module 410 can be ensured to be relatively smooth and flat.

[0049] In some embodiments, please refer to Figures 4 to 7, the wire drawing assembly 300 includes a fastening unit 310 for fastening the steel wire 420. The fastening unit 310 includes a fastener 311 and a screwing member 312. The fastener 311 includes a steel wire hole 311a for passing through the steel wire 420 and a threaded hole 311b. The steel wire hole 311a penetrates through the fastener 311, and the threaded hole 311b intersects with the steel wire hole 311a. The screwing member 312 is screwed into the threaded hole 311b, and the screwing member 312 can press against the steel wire 420. Through the cooperation of the fastener 311 and the screwing member 312, the steel wire 420 can be firmly fixed at a predetermined position, preventing the steel wire 420 from shifting during the forming process and ensuring the accuracy of the forming quality and the adhesion detection.

[0050] Specifically, please refer to Figure 7 , the steel wire hole 311a is specifically "L"-shaped. The steel wire 420 penetrates into one end of the steel wire hole 311a and passes out from the other end after being bent. The threaded hole 311b contacts and communicates with the steel wire hole 311a to form a "T" shape. The screwing member 312 is specifically a bolt, and the bolt screwed into the threaded hole 311b can press against the bent portion of the steel wire 420 to achieve the fixation of the steel wire 420.

[0051] In the specific implementation process, the steel wire 420 can be manually tightened, and then the tightening degree of the steel wire 420 can be adjusted by rotating the screwing member 312, enabling the operator to accurately adjust the tension and position of the steel wire 420 according to needs and ensuring the stability of the position and shape of the steel wire 420 during the forming process. The design of the fastener 311 and the screwing member 312 ensures that the steel wire 420 is subjected to uniform tensile force during the forming process, avoiding local stress concentration, thereby reducing the risk of fracture or deformation of the steel wire 420 and improving the stability of the forming process.

[0052] It should be noted that: the fastener 311 is spherical, and the outer frame 210 is provided with a positioning hole 211 adapted to the fastener 311. The spherical fastener 311 can freely rotate within the positioning hole 211, thereby automatically adapting to the straightening requirements of the steel wire 420 at different angles. Regardless of the initial position of the steel wire 420, the spherical fastener 311 can find the optimal straightening angle by rotating, improving the positioning accuracy and straightening effect of the steel wire 420.

[0053] The spherical fastener 311 can be freely adjusted within the positioning hole 211, enabling the tensile force received by the steel wire 420 during the straightening process to be evenly distributed, avoiding local stress concentration. It helps to reduce the risk of fracture or deformation of the steel wire 420 and ensure the quality of the formed model.

[0054] In some embodiments, please refer to Figure 4 and Figure 5, the wire drawing assembly 300 further includes an adjusting unit 320. The adjusting unit 320 includes an adjusting sleeve 321 for threading the wire 420. The adjusting sleeve 321 is specifically a threaded sleeve with a hollow middle, and the wire 420 is threaded through the adjusting sleeve 321. One end of the adjusting sleeve 321 is threadedly connected to the outer frame 210, and the other end of the adjusting sleeve 321 is connected to a fastening member 311. By means of the adjusting sleeve 321, the distance between the two fastening members 311 can be precisely controlled, thereby adjusting the tension of the wire 420. The tension of the wire 420 can be finely adjusted according to different forming requirements and material characteristics to ensure the best forming effect.

[0055] As a further implementation, please refer to Figure 5 , an adjusting ring 322 is provided on the adjusting sleeve 321. The adjusting ring 322 is coaxially arranged and fixedly connected with the adjusting sleeve 321. The diameter of the adjusting ring 322 is larger than that of the adjusting sleeve 321. The adjusting ring 322 can increase the contact area with the fingers for manual screwing of the entire adjusting sleeve 321. At the same time, the adjusting ring 322 can also be set to a hexagonal shape to facilitate adjustment using tools.
