Description

Technical Field

[0001] This utility model relates to the field of mold technology, and more specifically, to a dumbbell-shaped sample-taking die with a soft rubber structure. Background Technology

[0002] With the development of technology, MS adhesive has become a new generation of building sealant after silicone sealant SR and polyurethane sealant PU. It is mainly used in bonding, filling, jointing, sealing, waterproofing, and reinforcement in building engineering and decoration. As people's understanding of the advantages of MS adhesive continues to deepen, its application in refrigerated trucks, containers, elevator industry is also expanding. However, in the process of testing the performance of MS adhesive, there are situations where the sample is difficult to demold on the stainless steel mold and may injure the hands. A dumbbell-shaped sample preparation mold for MS multi-purpose structural adhesive has emerged, which will not cause injury to the hands, is convenient to use, highly efficient, and can be tested quickly. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides a dumbbell-shaped sample preparation and sampling die with a soft rubber structure, which has the advantage of ensuring the integrity of the sample.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dumbbell-shaped sampling die with a soft rubber structure, comprising an upper pressure plate, a base movably mounted on the bottom of the upper pressure plate, a second dumbbell-shaped groove formed on the inner outer surface of the upper pressure plate, a first dumbbell-shaped groove formed on the outer surface of the base, a dumbbell-shaped blade fixedly mounted inside the first dumbbell-shaped groove, the dumbbell-shaped blade extending one-third of the outer surface of the base and fitting into the second dumbbell-shaped groove, a spring fixedly connected to the outer surface of the base inside the dumbbell-shaped blade, the spring evenly distributed throughout the inner side of the dumbbell-shaped blade, a dumbbell-shaped holding plate fixedly connected to the other end of the spring, a locking mechanism fixedly mounted on the left side of the upper pressure plate, and a movable mechanism fixedly mounted on the left side of the upper pressure plate.

[0005] As a preferred technical solution of this utility model, the locking mechanism includes a fixed block fixedly installed on the left side of the upper pressure plate, a movable ball movably installed inside the fixed block, a movable groove opened on the bottom side of the fixed block, a limiting block fixedly installed directly below the left side of the fixed block of the base, a limiting groove opened on the inner side of the limiting block, a connecting rod fixedly connected to the bottom side of the movable ball and the connecting rod extending to the bottom side of the limiting block, and a limiting ball fixedly installed at the end of the connecting rod.

[0006] As a preferred embodiment of this utility model, the movable mechanism includes a pull handle fixedly installed on the left side of the upper pressure plate, and there are two pull handles located on both sides of the fixed block. The upper pressure plate and the base are hinged together by multiple hinges.

[0007] As a preferred embodiment of this utility model, a second dumbbell-shaped groove is provided on the inner outer surface of the upper pressure plate, a dumbbell-shaped blade is fixedly installed inside the first dumbbell-shaped groove, and the second dumbbell-shaped groove completely encloses the dumbbell-shaped blade.

[0008] As a preferred embodiment of this utility model, a limiting groove is provided on the inner side of the limiting block, and the limiting groove is T-shaped.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. In this invention, when the dumbbell-shaped blade touches the top of the second dumbbell-shaped groove, the sample is simultaneously pressed against the dumbbell-shaped holding plate by the dumbbell-shaped protrusions inside the second dumbbell-shaped groove. When the dumbbell-shaped holding plate is pressed, the springs on the inner side of the dumbbell-shaped blade, which are evenly distributed on the outer surface of the base, undergo elastic deformation. After pressing several times, the external force of the moving mechanism disappears, and the spring's elasticity restores the dumbbell-shaped holding plate, restoring the formed sample strip to a position higher than the dumbbell-shaped blade, making it easy to remove. The upper pressure plate and the base are made of wood, and the elastic deformation of the spring is within a tolerable range. Compared with traditional devices, this device allows operators to remove samples without reaching near the blade, greatly reducing the possibility of being cut by the blade and effectively ensuring the safety of the operator. It also enables rapid sample preparation, is convenient and efficient, and allows the sample to be completely removed from the die, ensuring that the shape and structure of the sample are not damaged, thus guaranteeing the quality of the sample and facilitating accurate testing and analysis of the sample later.

[0011] 2. This utility model uses a movable mechanism to drive the upper pressure plate and the base into a closed state. Then, external force causes the connecting rod to move to the inside of the limiting groove. Simultaneously, the opening of the movable groove facilitates the movement of the connecting rod, and the movable ball will move inside the fixed block. Then, due to the restoring effect of the spring, the fixed block, through the connecting rod, causes the limiting ball to be locked in the limiting groove. Since the width of the limiting ball is larger than the limiting groove, when it is needed, simply moving the connecting rod out of the limiting groove will release the lock. Compared with traditional devices, this device can prevent operators from accidentally touching the mold when moving, organizing equipment, or cleaning the work area, causing the upper and lower molds to close unexpectedly and pinching fingers, etc. It also avoids the blade from being chipped or deformed due to collision, thus effectively protecting the integrity of the mold.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 8As shown, this utility model provides a dumbbell-shaped sample preparation and sampling die with a soft rubber structure, including an upper pressure plate 1, a base 2 movably mounted on the bottom of the upper pressure plate 1, a second dumbbell-shaped groove 7 formed on the inner outer surface of the upper pressure plate 1, a first dumbbell-shaped groove 6 formed on the outer surface of the base 2, a dumbbell-shaped blade 3 fixedly mounted inside the first dumbbell-shaped groove 6, the dumbbell-shaped blade 3 extending one-third of the outer surface of the base 2 and fitting into the second dumbbell-shaped groove 7, a spring 4 fixedly connected to the outer surface of the base 2 inside the dumbbell-shaped blade 3, the spring 4 evenly distributed throughout the inner side of the dumbbell-shaped blade 3, a dumbbell-shaped holding plate 5 fixedly connected to the other end of the spring 4, a locking mechanism fixedly mounted on the left side of the upper pressure plate 1, and a movable mechanism fixedly mounted on the left side of the upper pressure plate 1.

[0023] When the staff first lifts the upper pressure plate 1 upwards using the movable mechanism, then places the sample on the base 2, and then uses the movable mechanism to remove the upper pressure plate 1, pressing it a few times, when the dumbbell-shaped blade 3 touches the top of the second dumbbell-shaped groove 7, the sample will be pressed against the dumbbell-shaped holding plate 5 by the dumbbell-shaped protrusion inside the second dumbbell-shaped groove 7. When the dumbbell-shaped holding plate 5 is pressed, the spring 4, which is evenly distributed on the outer surface of the base 2 and inside the dumbbell-shaped blade 3, will undergo elastic deformation. After pressing it a few more times, the external force of the movable mechanism will disappear, and the spring 4 will restore the dumbbell-shaped holding plate 5 to a position higher than the dumbbell-shaped blade 3 due to the elastic recovery effect, making it easy to remove. The upper pressure plate 1 and the base 2 are made of wood, and the elastic deformation of the spring 4 is within the acceptable range.

[0024] When the dumbbell-shaped blade 3 touches the top of the second dumbbell-shaped groove 7, the sample will be pressed against the dumbbell-shaped holding plate 5 by the dumbbell-shaped protrusions inside the second dumbbell-shaped groove 7. When the dumbbell-shaped holding plate 5 is pressed, the spring 4, which is evenly distributed on the outer surface of the base 2 and inside the dumbbell-shaped blade 3, will undergo elastic deformation. After pressing several more times, the external force of the moving mechanism will disappear, and the spring 4 will restore the dumbbell-shaped holding plate 5 to a position higher than the dumbbell-shaped blade 3 due to the elasticity of the spring, making it easy to remove. The upper pressure plate 1 and the base 2 are made of wood, and the elastic deformation of the spring 4 is within the acceptable range. Compared with traditional devices, this device allows operators to remove samples without having to reach near the blade, greatly reducing the possibility of being cut by the blade and effectively ensuring the safety of the operator. It can also quickly and easily prepare samples, and is efficient. It also allows the sample to be completely removed from the die, ensuring that the shape and structure of the sample are not damaged, thus ensuring the quality of the sample and facilitating accurate testing and analysis of the sample later.

[0025] The locking mechanism includes a fixed block 9 fixedly installed on the left side of the upper pressure plate 1, a movable ball 10 movably installed inside the fixed block 9, a movable groove 11 opened on the bottom side of the fixed block 9, a limiting block 12 fixedly installed directly below the fixed block 9 on the left side of the base 2, a limiting groove 13 opened on the inner side of the limiting block 12, a connecting rod 14 fixedly connected to the bottom side of the movable ball 10 and extending to the bottom side of the limiting block 12, and a limiting ball 15 fixedly installed at the end of the connecting rod 14.

[0026] When the mold is not needed, the upper pressure plate 1 and the base 2 are closed by the movable mechanism. Then, the connecting rod 14 is moved to the inside of the limiting groove 13 by external force. At the same time, the opening of the movable groove 11 facilitates the movement of the connecting rod 14. Then, the movable ball 10 will move inside the fixed block 9. Afterwards, due to the elasticity of the spring 4, the fixed block 9 is driven by the connecting rod 14 to lock the limiting ball 15 in the limiting groove 13. Since the width of the limiting ball 15 is greater than that of the limiting groove 13, when it is needed, the connecting rod 14 is moved outward out of the limiting groove 13, and the lock will be released.

[0027] The upper pressure plate 1 and the base 2 are closed by the movable mechanism. Then, the connecting rod 14 is moved to the inside of the limiting groove 13 by external force. At the same time, the opening of the movable groove 11 facilitates the movement of the connecting rod 14. Then, the movable ball 10 will move inside the fixed block 9. Afterwards, due to the elasticity of the spring 4, the fixed block 9 is driven by the connecting rod 14 to lock the limiting ball 15 in the limiting groove 13. Since the width of the limiting ball 15 is greater than that of the limiting groove 13, when it is needed, the connecting rod 14 only needs to be moved out of the limiting groove 13 to release the lock. Compared with the traditional device, this device can prevent the operator from accidentally touching the mold when moving, organizing the equipment or cleaning the work area, causing the upper and lower molds to close accidentally and pinching fingers, etc. It can also prevent the blade from being chipped or deformed due to collision, thus effectively protecting the integrity of the mold.

[0028] The active mechanism includes a pull handle 16 fixedly installed on the left side of the upper pressure plate 1, and there are two pull handles 16 located on both sides of the fixed block 9. The upper pressure plate 1 and the base 2 are hinged by multiple hinges 8.

[0029] By pulling the handle 16, there are two on both sides of the fixed block 9. The upper pressure plate 1 and the base 2 are hinged by multiple hinges 8, which makes it easy for the staff to open and close the upper pressure plate 1 and avoid safety problems due to the exposure of the dumbbell-shaped blade 3.

[0030] The upper pressure plate 1 has a second dumbbell-shaped groove 7 on its inner outer surface. A dumbbell-shaped blade 3 is fixedly installed inside the first dumbbell-shaped groove 6, and the second dumbbell-shaped groove 7 completely encloses the dumbbell-shaped blade 3.

[0031] The dumbbell-shaped blade 3 is completely enclosed by the second dumbbell-shaped groove 7, which makes it easy to remove excess sample and avoids excess sample residue.

[0032] The limiting block 12 has a limiting groove 13 on its inner side, and the limiting groove 13 is T-shaped.

[0033] The T-shaped limiting groove 13 allows the connecting rod 14 to move flexibly while the limiting ball 15 can be engaged in the limiting groove 13 at multiple positions, reducing the probability of locking failure.

[0034] Working principle and usage process of this utility model:

[0035] When the staff first lifts the upper pressure plate 1 upwards using the movable mechanism, then places the sample on the base 2, and then uses the movable mechanism to remove the upper pressure plate 1, pressing it a few times, when the dumbbell-shaped blade 3 touches the top of the second dumbbell-shaped groove 7, the sample will be pressed against the dumbbell-shaped holding plate 5 by the dumbbell-shaped protrusion inside the second dumbbell-shaped groove 7. When the dumbbell-shaped holding plate 5 is pressed, the spring 4, which is evenly distributed on the outer surface of the base 2 and inside the dumbbell-shaped blade 3, will undergo elastic deformation. After pressing it a few more times, the external force of the movable mechanism will disappear, and the spring 4 will restore the dumbbell-shaped holding plate 5 to a position higher than the dumbbell-shaped blade 3 due to the elastic recovery effect, making it easy to remove. The upper pressure plate 1 and the base 2 are made of wood, and the elastic deformation of the spring 4 is within the acceptable range.

[0036] When the mold is not needed, the upper pressure plate 1 and the base 2 are closed by the movable mechanism. Then, the connecting rod 14 is moved to the inside of the limiting groove 13 by external force. At the same time, the opening of the movable groove 11 facilitates the movement of the connecting rod 14. Then, the movable ball 10 will move inside the fixed block 9. Afterwards, due to the elasticity of the spring 4, the fixed block 9 is driven by the connecting rod 14 to lock the limiting ball 15 in the limiting groove 13. Since the width of the limiting ball 15 is greater than that of the limiting groove 13, when it is needed, the connecting rod 14 is moved outward out of the limiting groove 13, and the lock will be released.
