Description

Technical Field

[0001] The utility model relates to a mold for manufacturing adhesive tensile test specimens. Background Art

[0002] The contents of this section merely provide background information related to the present invention and may not constitute prior art.

[0003] To test the performance of an adhesive, a tensile test is typically performed on an adhesive tensile specimen made from the adhesive. The test results of the adhesive tensile specimen provide feedback on the adhesive's performance, and based on the test results, the formulation of the tested adhesive is optimized and improved in order to achieve the desired performance of the adhesive. In the existing process for preparing adhesive tensile specimens, the adhesive is coated on one surface of a backing paper, and then another backing paper is used to cover the coated adhesive, thereby sandwiching the adhesive between the two backing papers. The two backing papers with the adhesive sandwiched between them are then passed between two rollers, and the adhesive is distributed between the two backing papers through rolling, thereby obtaining an adhesive specimen with a thickness within the tolerance range. Finally, the rolled adhesive specimen is cut to obtain an adhesive tensile specimen with a predetermined outer contour.

[0004] In this existing manufacturing process, on the one hand, when the viscosity of the adhesive fluid is lower, the adhesive is easy to flow, thereby can not guarantee that the whole adhesive sample has uniform thickness, in order to ensure that the adhesive sample made meets the tolerance requirements, therefore also higher requirements are proposed to the experience of the operator, etc. On the other hand, after rolling, it is also necessary to carry out cutting secondary processing, and the whole preparation process of the adhesive tensile specimen is more. The more processes there are, the more accumulated errors will obviously be. Thus, in order to obtain the specimen within the tolerance range of the outer profile, it is necessary to control the precision of the secondary processing, thereby also increasing the difficulty of the secondary processing. In addition, in the cutting process, burrs or cracks will be formed on the outer edge of the adhesive tensile specimen cut, and this will affect the result of the tensile test carried out on the adhesive tensile specimen, can not truly reflect the true performance of the tested adhesive, therefore may affect the optimization and improvement of the tested adhesive.

[0005] Therefore, it is desirable to improve the preparation of adhesive tensile specimens, simplify the preparation process of adhesive tensile specimens, and improve the preparation quality of adhesive tensile specimens. Utility Model Content

[0024] The following description is merely illustrative in nature and is not intended to limit the present invention, its applications, and uses. It should be understood that throughout the drawings, like reference numerals indicate identical or similar parts and features. The drawings merely schematically illustrate the concepts and principles of the embodiments of the present invention and do not necessarily depict the specific dimensions and proportions of each embodiment of the present invention.

[0025] In the description of each embodiment of the present invention, the directional terms related to "up", "down", "left", "right", "front" and "back" are used to describe the orientation of up, down, left, right, front and back in the view.

[0026] Figure 1 FIG1 shows a plan view of an adhesive tensile specimen S. Figure 1 As shown, the adhesive tensile specimen S includes a first part S1, a second part S2, and a third part S3 located between the first part S1 and the second part S3. The third part S3 is a part used for performing a tensile test, and the test results of this part reflect the performance of the adhesive being tested. The third part has a width W1. The first part S1 and the second part S2 are used to fix the third part S3 from both ends during the tensile test for performing the tensile test, and the widths of the first part S1 and the second part S2 are greater than the width of the third part S3. In the example shown in the figure, the first part S1 and the second part S2 have the same width W2, and the width W2 is smaller than the width W1 of the third part S3. However, there is no particular limitation on the widths of the first part S1 and the second part S2, as long as the third part S3 can be fixed in place during the tensile test. In addition, the lengths of the first part S1, the second part S2, and the third part S3 can be set according to the requirements of the tensile test to be performed.

[0027] Figure 2 FIG2 shows a perspective view of a mold 1 for manufacturing an adhesive tensile specimen S according to a preferred embodiment of the present invention. Figure 3 An exploded view of the mold 1 is shown. Figure 2 and Figure 3 As shown, the mold 1 includes a fixing part 10 , a contour part 20 and an adjusting part 30 .

[0028] Best as Figure 3 As shown, the fixing member 10 includes a fixing base 11 and a fixing protrusion 12. The fixing protrusion 12 extends from one side of the fixing base 11 ( Figure 3 The right side of the Figure 1The fixing protrusion 12 includes a first end portion 121, a second end portion 122, and a middle portion 123. The middle portion 123 connects the first end portion 121 and the second end portion 122, and the width of the middle portion 123 is smaller than the widths of the first end portion 121 and the second end portion 122. The first end portion 121 and the second end portion 122 have the same or corresponding outer contours (length, width, planar shape) as the first portion S1 and the second portion S2 of the adhesive tensile specimen S, respectively. The middle portion 123 has the same or corresponding outer contours (length, width, planar shape) as the third portion S3 of the adhesive tensile specimen S.

[0029] One of the first end portion 121 and the second end portion 122 is provided with an injection hole for injecting adhesive during the injection molding process, and the other of the first end portion 121 and the second end portion 122 is provided with an exhaust hole for exhausting gas during the injection molding process. In the example shown in the figure, the first end portion 121 is provided with an exhaust hole 125, and the second end portion 122 is provided with an injection hole 124. The injection hole 124 and the exhaust hole 125 penetrate the second end portion 122 and the first end portion 121 respectively, and are connected to the cavity of the mold 1 (which will be discussed below). Figure 6 During the manufacturing process of the adhesive tensile specimen S, the glue injection needle 60 is inserted into the injection hole 124 to inject the adhesive fluid (e.g., liquid adhesive) used to prepare the adhesive tensile specimen into the cavity of the mold 1. The vent hole 125 is used to exhaust the gas in the cavity of the mold 1.

[0030] The profile member 20 is formed with a through groove 21. The through groove 21 penetrates the profile member 20 and has a profile that is the same as or corresponds to the outer profile of the fixing protrusion 12 of the fixing member 10 (that is, the outer profile of the adhesive tensile specimen S to be manufactured). The profile member 20 is detachably mounted to the fixing member 10 so that the profile member 20 is located on the first opening side ( Figure 3 The left side in FIG) cooperates with the fixing member 10 so that the fixing protrusion 12 is at least partially fitted in the through groove 21.

[0031] The adjusting member 30 includes an adjusting base 31 and an adjusting protrusion 32. The adjusting protrusion 32 extends from one side of the adjusting base 31 ( Figure 3The adjusting protrusion 32 protrudes from the through groove 21 (left side in the figure), and the outer contour of the adjusting protrusion 32 is the same as or corresponds to the contour of the through groove 21 (that is, the outer contour of the adhesive tensile specimen S to be manufactured). The adjusting protrusion 32 includes a first end 321, a second end 322, and a middle portion 323. The middle portion 323 connects the first end 321 and the second end 322, and the width of the middle portion 323 is smaller than the widths of the first end 321 and the second end 322. The first end 321 and the second end 322 have outer contours (length, width, planar shape) that are the same as or correspond to the first portion S1 and the second portion S2 of the adhesive tensile specimen S, respectively, and the middle portion 323 has an outer contour (length, width, planar shape) that is the same as or corresponds to the third portion S3 of the adhesive tensile specimen S.

[0032] The adjusting member 30 is detachably mounted to the contour member 20 so that the through slot 21 is located at a second opening side ( Figure 3 The right side in the figure) cooperates with the adjusting protrusion 32 so that the adjusting protrusion 32 is at least partially fitted in the through groove 21.

[0033] When the mold 1 is installed in place, the fixing member 10, the contour member 20 and the adjusting member 30 jointly define the cavity located in the through groove 21 ( Figure 6 The mold cavity V is shown in FIG. Specifically, in the example shown in the figure, the end face of the fixing protrusion 12 of the fixing member 10 forms one side of the mold cavity, the end face of the adjusting protrusion 32 of the adjusting member 30 forms the other side of the mold cavity, and the peripheral wall of the portion of the through-channel 21 located between the fixing protrusion 12 and the adjusting protrusion 32 forms the peripheral wall of the mold cavity. The fixing protrusion 12, the adjusting protrusion 32, and the through-channel 21 all have an outer contour identical to or corresponding to the outer contour of the adhesive tensile specimen S to be manufactured. Therefore, the formed mold cavity also has an outer contour identical to or corresponding to the outer contour of the adhesive tensile specimen S to be manufactured. Therefore, the adhesive tensile specimen S can be manufactured by injecting an adhesive fluid into the mold cavity for injection molding.

[0034] Compared to the existing preparation process of preparing adhesive tensile specimens by coating the adhesive on a backing paper and then rolling and cutting, when the mold 1 according to the present invention is used to prepare the adhesive tensile specimen, it is possible to ensure that the manufactured adhesive tensile specimen has a uniform thickness regardless of the viscosity of the adhesive fluid. In addition, because the outer contour of the mold cavity is the same as or corresponds to the outer contour of the adhesive tensile specimen to be manufactured, the injection molded part obtained by injection molding has an outer contour that is the same as or corresponds to that of the adhesive tensile test specimen, without the need to subsequently cut the outer contour of the injection molded part, especially the middle part to be subjected to the tensile test, thereby reducing the preparation process and avoiding the disadvantages associated with cutting in the existing preparation process (for example, burrs or cracks formed by cutting).

[0035] Preferably, at least the surfaces of the mold 1 that come into contact with the adhesive fluid are treated with an anti-sticking treatment, such that at least the surfaces of the cavity V of the mold 1 are anti-sticking surfaces, thereby facilitating demolding of the injection-molded part of the prepared adhesive tensile test specimen. In one embodiment, the surfaces of the fixing member 10, the contour member 20, and the adjusting member 30 of the mold 1 are all anti-sticking surfaces.

[0036] Preferably, the fixing member 10 , the contour member 20 and the adjusting member 30 are all made of metal material, preferably high-strength metal material, so as to improve durability and ensure that the mold 1 has a longer service life.

[0037] Preferably, mold 1 further includes multiple sets of height limiting members of varying heights. One set of these sets of height limiting members is removably mounted to fixture 10, allowing for adjustment of the depth of engagement of fixture 10's fixing protrusion 12 within through-slot 21 of profile member 20 as needed, thereby preparing adhesive tensile test specimens of varying thicknesses. During use, a set of height limiting members of a corresponding height from the multiple sets of height limiting members can be mounted to fixture 10 based on the thickness of the adhesive tensile test specimen being prepared.

[0038] Figure 2 and Figure 3 A group of height limiting members in the form of height limiting blocks is schematically shown in the figure. The group of height limiting members includes a first height limiting block 41 and a second height limiting block 42 of the same height. The fixing base 11 of the fixing member 10 is provided with a first mounting groove 111 and a second mounting groove 112, and the fixing protrusion 12 is located between the first mounting groove 111 and the second mounting groove 112. When in use, the first height limiting block 41 is detachably mounted to the first mounting groove 111, and the second height limiting block 42 is detachably mounted to the second mounting groove 112. When installed in place, the first height limiting block 41 and the second height limiting block 42 respectively abut against opposite ends of the contour member 20, thereby limiting the depth of the fixing protrusion 12 fitted into the through groove 21 of the contour member 20.

[0039] Preferably, mold 1 further includes an adjustment screw detachably mounted to adjustment member 30 and adapted to abut against profile member 20. During assembly of mold 1 in preparation for injection molding, the adjustment screw can be used to adjust the depth at which adjustment protrusion 32 of adjustment member 30 fits within through-slot 21. Furthermore, during demolding after injection molding, the adjustment screw can be used to apply force to profile member 20 to facilitate demolding.

[0040] Figure 2 and Figure 3FIGURE 2 schematically illustrates an embodiment of the aforementioned adjusting screw. In the example shown, the adjusting screw comprises screws 53 and 54, as well as locknuts 55 and 56. Screws 53 and 54 can be screwed into corresponding adjustment screw holes (not shown) in the adjusting member 30. Locknuts 55 and 56 engage with screws 53 and 54, respectively, and abut against the adjusting member 30 to define the length of the screws 53 and 54 extending from the adjusting member 30. The ends of screws 53 and 54 extending from the adjusting member 30 are adapted to abut against the profile 20, thereby adjusting the depth of the adjusting protrusion 32 of the adjusting member 30 within the through-slot 21 of the profile 20. Prior to injection molding, the depth of the mold cavity 1 can be further adjusted as needed by adjusting screws 53 and 54. For the preparation of adhesive tensile test specimens of a predetermined thickness, the length of the screws 53 and 54 extending from the adjusting member 30 is set by engaging with the locknuts 55 and 56. After injection molding is completed, demoulding can be facilitated by adjusting screws 53, 54, as will be described below.

[0041] Preferably, the mold 1 further comprises fixing screws for detachably fixing the adjusting member to the fixing member 10, thereby holding the various components of the mold 1 in place, thereby facilitating stable injection molding of the adhesive tensile test specimen. Figure 2 and Figure 3 In the example shown, the mold 1 includes a fixing screw 51 and a fixing screw 52, ​​which can be respectively passed through the through holes ( Figure 6 and engage with the corresponding threaded holes ( Figure 6 The adjusting member 30 is fixed to the fixing member 10 in a detachable manner by inserting the threaded hole 113, the threaded hole 114 in the mold 1, and thereby the contour member 20 and the height limiting member (the first height limiting block 41, the second height limiting block 42) of the mold 1 are kept in place.

[0042] The above describes the structures of the various parts of the mold 1 for manufacturing an adhesive tensile test specimen according to a preferred embodiment of the present invention.

[0043] The following will be combined Figures 4 to 13 The following describes a process for manufacturing adhesive tensile test specimens using a mold 1 according to a preferred embodiment of the present invention, which includes three steps: assembling the mold 1 , injection molding, and demoulding.

[0044] The assembly process of the mold 1 is as follows. First, install the height limiting member to the fixing member 10. Figure 4As shown, the first height limiting block 41 and the second height limiting block 42 are respectively installed in the first installation groove 111 and the second installation groove 112 of the fixing member 10. Next, the contour member 20 is installed on the fixing member 10, and the first height limiting block 41 and the second height limiting block 42 are respectively against the two ends of the contour member 20, as shown in FIG. Figure 5 As shown, the depth of the fixing protrusion 12 of the fixing member 10 fitting into the through groove 21 of the contour member 20 is defined.

[0045] Then, the adjusting member 30 is detachably mounted to the contour member 20 so that the adjusting protrusion 32 of the adjusting member 30 is partially fitted into the through groove 21 of the contour member 20. Thus, the fixing protrusion 12, the adjusting protrusion 32 and the through groove 21 jointly define the cavity V of the mold 1, as shown in FIG. Figure 6 shown.

[0046] Preferably, the fixing screws 51 and 52 are respectively passed through the through holes 313 and 314 on the adjusting member 30 and engaged in the corresponding threaded holes 113 and 114 on the fixing member 10, thereby fixing the adjusting member 30 to the fixing member 10 in a detachable manner, and thereby holding the contour member 20, the first height limiting block 41, and the second height limiting block 42 of the mold 1 in place, as shown in FIG. Figure 7 As shown, the assembly of the mold 1 is completed.

[0047] Next, injection molding of the adhesive tensile specimen is performed. The assembled mold 1 is erected so that the vent 125 is located at the top and the injection hole 124 is located at the bottom. Subsequently, the glue injection needle 60 is inserted into the injection hole 124 to inject the adhesive fluid (for example, liquid adhesive) used to prepare the adhesive tensile specimen into the cavity V of the mold 1. As the adhesive fluid is injected, the air in the cavity V flows upward and is discharged through the vent 125, thereby reducing bubbles in the prepared injection-molded part and improving the injection molding quality. When the adhesive fluid exceeds the position of the vent 125 in the cavity V, it means that the adhesive fluid in the cavity V is sufficient, and the excess adhesive fluid can flow into the vent 125 and flow outward. Figure 8 When it is found that the adhesive fluid flows out from the vent hole, the injection of the adhesive fluid can be ended.

[0048] Subsequently, the entire mold 1 can be heated to solidify the adhesive fluid in the mold 1 to form an injection molded part. The adhesive fluid in the mold cavity V solidifies to form the main body M1, while the adhesive fluid remaining in the vent hole 125 solidifies to form the residual material M2. Figure 9 Thus, the injection molding of the adhesive tensile test specimen is completed.

[0049] Then, demoulding is performed to remove the injection molded part of the adhesive tensile test specimen from the mold 1. Specifically, first, the first height limiting block 41 and the second height limiting block 42 are removed from the fixing member 10. In this process, in order to facilitate the removal of the first height limiting block 41 and the second height limiting block 42, the fixing screws 51 and the fixing screws 52 can be loosened appropriately, while the fixing screws 51 and the fixing screws 52 are still engaged with the threaded holes 113 and the threaded holes 114 of the fixing member 10, respectively, as shown in FIG. Figure 10 Alternatively, the fixing screws 51 and 52 can be completely removed from the fixing member 10, thereby making it easier to remove the first height limiting block 41 and the second height limiting block 42. Then, the contour member 20 is pressed toward the fixing member 10 to move the contour member 20 toward the fixing member 20, so that the main body M1 of the molded part is disengaged from the through groove 21 of the contour member 20, as shown. Figure 11 In this process, for example, the screws 53 and 54 can be screwed so that the length of the screws 53 and 54 extending from the adjusting member 30 increases, thereby squeezing the contour member 20 toward the fixing member 10. Next, as shown in FIG. Figure 12 As shown, the profile member 30 is disassembled. If the fixing screws 51 and 52 are not completely removed from the fixing member 10 when the first height limiting block 41 and the second height limiting block 42 are previously disassembled, the fixing screws 51 and 52 are first removed from the fixing member 10 before disassembling the profile member 30. Then, the injection molded part is removed from the fixing member 10, as shown in FIG. Figure 13 Subsequently, the remaining material portion M2 of the injection molded part is removed, for example, by cutting. After the remaining material portion M2 is cut off, the main body portion M1 is the prepared adhesive tensile specimen S, thereby completing the preparation of the adhesive tensile specimen S.

[0050] Since the vent hole 125 is provided in the first end portion 121 corresponding to the first portion S2 of the adhesive tensile specimen S, even if burrs are generated when the residual material portion M2 is cut off, the middle portion of the main body M1 used for the tensile test will not be affected, thereby not affecting the test of the adhesive tensile specimen S.

[0051] According to the mold 1 of the present invention, the contour of the cavity V corresponds to the outer contour of the adhesive tensile specimen S. The adhesive tensile specimen can be prepared by injection molding, ensuring that the prepared adhesive tensile specimen has a uniform thickness without being affected by the viscosity of the adhesive fluid. This is conducive to standardizing the preparation process of the adhesive tensile specimen, reducing the preparation process, and facilitating the control of the tolerance of the prepared adhesive tensile specimen. This allows the adhesive properties to be accurately reflected by performing tensile tests on the prepared adhesive tensile specimens, thereby facilitating the improvement of the adhesive formulation based on the test results. Experiments have shown that when using the mold 1 according to the present invention to prepare adhesive tensile specimens with a thickness ranging from 0.1 mm to 6 mm, the thickness tolerance of the prepared adhesive tensile specimens can be controlled within 5%, and the prepared adhesive tensile specimens can well meet the tolerance requirements. In one experiment, when using the mold 1 according to the present invention to prepare an adhesive tensile specimen with a thickness of 6 mm, the tolerance can be controlled to ±0.1 mm. In addition, advantageously, the mold 1 according to the present invention can conveniently set the depth of the cavity as needed, so that adhesive tensile specimens of different thicknesses can be prepared as needed, and has good applicability.

[0052] While exemplary embodiments of a mold for manufacturing adhesive tensile specimens according to the present invention have been described in detail herein, it should be understood that the present invention is not limited to the specific embodiments described and illustrated above. Those skilled in the art will be able to implement various combinations, modifications, and variations of the present invention without departing from the spirit and scope of the present invention. All such combinations, modifications, and variations fall within the scope of the present invention. Furthermore, all components described herein may be replaced by other technically equivalent components.
