Description

Technical Field

[0002] Silicone adhesive is an ointment-like adhesive, the main ingredients of which are sodium silicate, acetic acid and organic silicone. It is also a material that solidifies into a tough rubber-like solid once it comes into contact with moisture in the air. In order to ensure that its quality, performance and safety meet relevant standards and application requirements, the performance of silicone adhesive needs to be tested;

[0003] In the prior art, an experimental mold is usually used to test the performance of silicone adhesive. For example, a Chinese patent with a publication number of CN112240852B discloses an experimental mold for testing the performance of silicone adhesive. The mold uses a movable mold, a fixed mold and a heating coil. The movable mold can be clamped with different experimental models. At the same time, the silicone adhesive can be heated by the heating coil to test its strength change at different temperatures, thereby improving the functionality of the test mold to a certain extent.

[0004] When using the silicone glue test mold in the prior art, it is necessary to manually apply silicone glue to the mold surface. This test method will result in the shape and specifications of the silicone glue sample cannot be effectively controlled, and the contact area between the silicone glue and the mold will directly affect the test accuracy of the silicone glue bonding accuracy, thereby resulting in large errors in the silicone glue test results.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 9 , an experimental mold for testing the performance of silicone adhesive, comprising a drying oven 12, an operating table 11 is fixedly connected to the outer surface of the lower end of the drying oven 12, a support plate 16 is fixedly connected to the outer surface of the upper end of the operating table 11, and a shaping component is arranged on the upper side of the support plate 16;

[0035] The shaping component includes a hinge part and an extrusion part, the support plate 16 is movably connected to the lower mold 19 through the hinge part, the extrusion part includes an electric push rod 26 fixedly connected to the upper end of the inner surface of the drying box 12, the lower end outer surface of the electric push rod 26 is fixedly connected to the upper mold 27, the upper end outer surface of the lower mold 19 is provided with a scale line 50, the middle part of the lower end outer surface of the upper mold 27 is provided with a shaping hole 37, the inner side of the upper mold 27 is embedded with an injection hole 32, one end of the injection hole 32 passes through to the front side of the upper mold 27 and the other end is connected to the inside of the shaping hole 37.

[0036] The hinged portion includes a pin shaft 17 rotatably connected to the left and right ends of the support plate 16, and the left and right ends of the pin shaft 17 are fixedly connected to ear seats 18. The number of the ear seats 18 is two groups and they are symmetrically distributed. The upper outer surface of the ear seat 18 is fixedly connected to the lower outer surface of the lower mold 19, and the shaping hole 37 is semi-cylindrical.

[0037] By adopting the above technical solution, the operating table 11 supports the drying box 12, the drying box 12 fixes and supports the upper mold 27 through the electric push rod 26, and the support plate 16 supports the pin shaft 17, so that the support plate 16 and the lower mold 19 are hinged through the cooperation of the pin shaft 17 and the ear seat 18. When testing the sag of the silicone glue, first make the upper surface of the lower mold 19 horizontal, and then start the electric push rod 26, and drive the upper mold 27 to move downward through the electric push rod 26 so that the lower surface of the upper mold 27 fits on the upper surface of the lower mold 19. The upper mold 27 and the lower mold 19 are closely fitted to cooperate with the shaping hole 37 to form a closed cavity between the upper mold 27 and the lower mold 19, and then the operator injects material into the shaping hole 37 through the injection hole 32 on the inner side of the upper mold 27. An appropriate amount of silicone glue is injected, so that the silicone glue can be extruded and shaped through the upper mold 27 and the lower mold 19 in coordination with the shaping hole 37, and then the upper mold 27 is lifted upward by the electric push rod 26 to separate the upper mold 27 and the lower mold 19, so that the silicone glue sample can be tested for horizontal slump on the upper surface of the lower mold 19. The scale line 50 opened on the surface of the lower mold 19 can facilitate the experimenter to intuitively measure the deformation of the silicone glue, thereby improving the convenience of the test operation to a certain extent. By setting the molding component, the specifications and sizes of the silicone glue samples can be kept consistent, and the initial structural shape of the silicone glue samples can be kept consistent, so that the silicone glue performance can be better compared and analyzed, and then the test error can be effectively reduced, and the accuracy of silicone glue performance testing can be improved.

[0038] like Figure 3 , Figure 4 , Figure 8 and Fig. 9 As shown, an adjustment component is provided on the lower side of the lower mold 19, and the adjustment component includes a guide plate 38 fixedly connected to the outer surface of the lower end of the lower mold 19, a guide groove 39 is provided on the outer surface of the guide plate 38, a notch 42 is provided on the outer surface of the front end of the support plate 16, the guide plate 38 passes through the notch 42 to the rear side of the support plate 16, and a scale line 43 is provided on the outer surface of the right end of the guide plate 38.

[0039] The guide plate 38 and the guide groove 39 are both arc-shaped, and the inner surface of the groove 42 is fixedly connected to a movable sleeve 40. The movable sleeve 40 is in sliding contact with the guide plate 38 through the guide groove 39. The inner surface of the movable sleeve 40 is rotatably connected to an adjusting rod 41, and the outer surface of the adjusting rod 41 is spirally connected to an extrusion sleeve 25. The extrusion sleeve 25 is located between the guide plate 38 and the support plate 16. The adjusting rod 41 penetrates to the right side of the support plate 16 and is rotatably connected to the support plate 16.

[0040] By adopting the above technical solution, in order to experimentally analyze the droop of the silicone glue at different angles during the test, an adjustment component is set. When the adjustment component is working, the operator twists the adjustment rod 41 to slide the adjustment rod 41 to the side away from the guide plate 38. The adjustment rod 41 will drive the extrusion sleeve 25 to break contact with the guide plate 38 during the movement. At this time, the lower mold 19 is rotated with the pin 17 as the fulcrum to adjust the angle of the lower mold 19. The lower mold 19 will drive the guide plate 38 to move synchronously during the flipping process. At the same time, the lower end of the guide plate 38 will pass through the notch 42 on the surface of the support plate 16, and the movable sleeve 40 inside the notch 42 will contact the guide plate 38 through the guide groove 39. The guide plate 38 is slidably guided, so that the guide plate 38 and the lower mold 19 can be turned over more smoothly. When the lower mold 19 is turned over to an appropriate angle, the operator twists the adjusting rod 41 in the opposite direction to move the adjusting rod 41 toward the side of the guide plate 38. The guide plate 38 can be locked and limited by squeezing the extrusion sleeve 25, so that the guide plate 38 and the lower mold 19 can remain in a stationary state. The scale line 43 on the surface of the guide plate 38 can cooperate with the support plate 16 to intuitively observe the turning angle of the lower mold 19, so that the silicone sag and horizontal collapse experiments at different angles can be performed, thereby effectively improving the functionality and flexibility of the experimental mold.

[0041] like Figure 5 , Figure 6 and Fig. 9 As shown, a test assembly is provided on the upper side of the lower mold 19, and the test assembly includes a movable groove 44 opened on the outer surface of the upper end of the lower mold 19, and a fixed frame 46 is slidably connected to the inner side of the movable groove 44. The fixed frame 46 is a U-shaped structure, and a displacement groove 49 is opened on the outer surface of the upper end of the fixed frame 46. The fixed frame 46 is slidably connected to a slide 48 through the displacement groove 49. The number of the slides 48 is two groups and they are symmetrically distributed. The outer surface of the slide 48 is spirally connected to a drive rod 45, and the outer surface of the drive rod 45 is symmetrically provided with spiral grooves.

[0042] The left and right ends of the driving rod 45 pass through the outside of the fixing frame 46 and are rotatably connected to the fixing frame 46. The lower end of the sliding seat 48 is fixedly connected to a clamping plate 47, and the clamping plate 47 is arc-shaped. The outer surface of the rear end of the lower mold 19 is fixedly connected to an ear seat 20, and a pin shaft 24 is fixedly connected between the two groups of the ear seats 20. The outer surface of the pin shaft 24 is rotatably connected to a guide roller 21.

[0043] A support plate 51 is fixedly connected to the outer surface of the rear end of the support plate 16, a dynamometer 52 is fixedly connected to the outer surface of the upper end of the support plate 51, a traction bar 22 is fixedly connected to the upper end of the dynamometer 52, the traction bar 22 is in rotational contact with the outer surface of the guide roller 21, a pull plate 23 is fixedly connected to the upper end of the traction bar 22, a strong clamp 24 is fixedly connected to the side of the pull plate 23 away from the traction bar 22, and the pull plate 23 is arc-shaped and made of elastic material.

[0044] By adopting the above technical scheme, the tensile strength of silicone glue is also one of the key factors affecting its performance. When testing the tensile strength of silicone glue, first move the U-shaped fixing frame 46 to the rear end of the movable groove 44, and block and limit the fixing frame 46 through the movable groove 44. The displacement groove 49 on the surface of the fixing frame 46 can slide and guide the slide 48, so that the two groups of slides 48 can slide linearly. The operator twists the driving rod 45, and the symmetrically distributed spiral grooves on the surface of the driving rod 45 can drive the two groups of slides 48 to move toward each other. During the movement, the slide 48 will drive the clamp 47 at its lower end to move synchronously. The front end of the silicone glue sample is clamped by the two groups of clamps 47, and then the rear end of the silicone glue sample is clamped by the strong clamp 24. The support plate 16 fixes and supports the dynamometer 52 through the support plate 51, and the strong clamp 24 and the dynamometer 52 are connected by the pull plate 23 and the traction bar 22 The lower mold 19 is connected to each other, and the lower mold 19 is fixedly supported by the pin shaft 2 54 through the ear seat 20, so that the guide roller 21 is rotationally supported by the pin shaft 2 54, and the traction bar 22 is rotationally guided by the guide roller 21. After the two ends of the silicone glue are clamped, the operator rotates the lower mold 19. When the lower mold 19 rotates with the pin shaft 17 as the fulcrum, it will drive the guide roller 21 to move synchronously through the ear seat 20. At this time, the distance between the guide roller 21 and the support plate 51 will increase accordingly. At this time, the traction bar 22 will stretch the pull plate 23, so that the pull plate 23 has a certain elastic deformation to increase the clamping force of the strong clamp 24. During the flipping process of the lower mold 19, the traction bar 22 will stretch the silicone glue sample through the strong clamp 24. The tensile strength of the silicone glue sample can be effectively detected by the dynamometer 52. By setting the test component, various performance parameters of the silicone glue can be tested and analyzed, thereby effectively improving the application range of the test mold.

[0045] like Figure 3 and Figure 7As shown, a material distribution component is arranged on the inner side of the drying box 12, and the material distribution component includes a fixed sleeve 15 fixedly connected to the upper end of the inner surface of the drying box 12, and the fixed sleeve 15 is located on the outer side of the electric push rod 26. The inner surface of the fixed sleeve 15 is fixedly connected to a limit plate 30, and the outer surface of the lower end of the limit plate 30 is fixedly connected to a positioning plate 31. A slide groove 33 is embedded in the inner side of the lower mold 19, and the slide groove 33 extends to the upper end of the lower mold 19, and the slide groove 33 is located directly below the positioning plate 31.

[0046] A second slide groove 34 is embedded in the inner side of the slide groove 1 33, a slide rod 35 is slidably connected to the inner side of the second slide groove 34, a slide plate 36 is fixedly connected to the outer surface of the lower end of the slide rod 35, the slide plate 36 is located inside the slide groove 1 33 and is in sliding contact with the inner surface of the slide groove 1 33, the lower end of the slide groove 1 33 is connected to the front end of the forming hole 37, a spring 53 is fixedly connected to the outer surface of the upper end of the slide rod 35, and the upper end of the spring 53 is fixedly connected to the upper end of the inner surface of the second slide groove 34.

[0047] By adopting the above technical scheme, during the silicone glue injection and shaping process, in order to improve the molding quality of the silicone glue sample, a material dividing component is set, and the drying box 12 fixes and supports the positioning plate 31 through the fixing sleeve 15. After the silicone glue is extruded and shaped, when the upper mold 27 moves upward, the positioning plate 31 will be inserted into the inside of the slide groove 1 33 on the surface of the upper mold 27, and the slide bar 35 inside the slide groove 2 34 will be squeezed by the positioning plate 31, so that the slide plate 36 is driven by the slide bar 35 to slide and extrude toward the lower side of the slide groove 1 33, and the silicone glue sample inside the shaping hole 37 can be assisted to fall under the push of the slide plate 36, and the silicone glue material between the injection hole 32 and the shaping hole 37 can be cut by the slide plate 36, so as to effectively improve the molding quality of the silicone glue sample and make the silicone glue sample more regular. When the upper mold 27 moves downward, the slide bar 35 moves in the opposite direction and resets under the elastic force of the spring 53, so that the silicone glue can enter the shaping hole 37 through the injection hole 32.

[0048] like Figure 1 , Figure 3 and Figure 4 As shown, a mounting plate 13 is fixedly connected to the inner surface of the drying box 12, a heating lamp 14 is fixedly connected to the outer surface of the lower end of the mounting plate 13, the mounting plates 13 and the heating lamps 14 are in two groups and are symmetrically distributed, a sealing groove 29 is provided on the outer surface of the upper end of the lower mold 19, a sealing plate 28 is fixedly connected to the outer surface of the lower end of the upper mold 27, and the sealing groove 29 is located directly below the sealing plate 28.

[0049] By adopting the above technical solution, when the lower mold 19 is attached to the surface of the upper mold 27, the sealing plate 28 will be engaged with the inside of the sealing groove 29, so that the upper mold 27 and the lower mold 19 can be sealed, thereby reducing the probability of leakage during the silicone glue injection process. The drying oven 12 fixes and supports the baking lamp 14 through the mounting plate 13, so that the drying and molding of the silicone glue can be accelerated by the irradiation of the baking lamp 14, thereby improving the silicone glue testing efficiency to a certain extent. At the same time, the silicone glue sample is irradiated by the baking lamp 14, which can simulate the changes in the performance parameters of the silicone glue under lighting conditions, thereby further improving the application range of the test mold.

[0050] Instructions for use: During the silicone performance test, the upper mold 27 is driven downward by the electric push rod 26 to fit the upper mold 27 on the upper surface of the lower mold 19, and a sufficient amount of silicone is injected into the shaping hole 37 through the injection hole 32 on the inner side of the upper mold 27, so that the silicone can be extruded and shaped through the upper mold 27 and the lower mold 19 in coordination with the shaping hole 37. The drying and forming of the silicone is accelerated by the irradiation of the baking lamp 14, and then the angle of the lower mold 19 is adjusted. After the lower mold 19 is turned over to an appropriate angle, the guide plate 38 can be locked and limited by squeezing the extrusion sleeve 25, and the silicone deformation can be adjusted by the scale line 1 43 and the scale line 2 50. During the measurement, the front end of the silicone rubber sample is clamped by two groups of clamps 47, and the rear end of the silicone rubber sample is clamped by the strong clamp 24. When the lower mold 19 is flipped, the traction bar 22 stretches the silicone rubber sample through the strong clamp 24. The tensile strength of the silicone rubber sample can be effectively tested by the dynamometer 52. The slide bar 35 drives the slide plate 36 to slide and squeeze the lower side of the slide groove 33. The slide plate 36 can assist the silicone rubber sample in falling out of the forming hole 37 under the push of the slide plate 36. At the same time, the slide plate 36 can cut the silicone rubber material between the injection hole 32 and the forming hole 37, thereby effectively improving the molding quality of the silicone rubber sample.
