Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to stress testing equipment for mold manufacturing. Background Technology

[0002] Molds are specialized tools used in industrial production to precisely shape and size metals, plastics, and rubber. They serve as a core bridge connecting raw materials and finished products. Whether it's the casing of everyday items, automotive parts, or precision structural components of electronic devices, most require initial shaping through molds. Their design and precision directly determine the basic form of the product. A qualified mold can be reused thousands or even tens of thousands of times, effectively reducing the production cost of a single product while ensuring that the size and appearance of each batch of products are highly consistent, avoiding errors caused by manual processing. Molds are indispensable equipment for modern manufacturing to achieve standardized and efficient production.

[0003] Mold manufacturing is a process that transforms raw materials such as metal into high-precision forming tools, encompassing design, processing, assembly, and trial molding. It demands extremely high precision and stability in its processes. From the initial design of the mold structure based on product drawings to later adjustments and optimizations through trial molding, each step directly impacts the final mold's lifespan and the product's forming quality. However, stress testing is often necessary during production. With technological advancements, stress testing equipment for mold manufacturing is a specialized instrument for detecting the distribution and magnitude of internal stress before manufacturing and use. It is crucial for ensuring mold quality and lifespan. During mold processing, cutting and heat treatment can easily generate residual stress inside the mold. If this stress is not detected and adjusted in time, it may lead to deformation and cracking during subsequent use. This equipment can accurately capture these potential risks, providing data support for quality control in mold production. However, current stress testing methods have significant limitations. Due to the lack of targeted testing solutions for products of different sizes and models, companies often need to invest more resources and time in product development and quality control, significantly increasing overall testing and production costs, and consequently reducing testing efficiency.

[0031] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4An embodiment of this utility model provides a stress testing device for mold production, including a working surface 1, a clamping mechanism 2 at the top center of the working surface 1 for clamping and testing the mold, a lifting mechanism 3 at the bottom of the working surface 1 for raising and lowering the working surface 1, a pressing mechanism 4 at the top of the working surface 1 for pressing and testing, and a protective shell 6 at the bottom of the working surface 1 for protecting and supporting the internal structure.

[0033] The clamping mechanism 2 includes a U-shaped clamping plate 201. The bottom of the U-shaped clamping plate 201 is slidably connected to the top of the working surface 1. A handle 202 is connected to the right side of the U-shaped clamping plate 201. Multiple connecting plates are fixedly connected to the front and rear sides of the U-shaped clamping plate. A one-way threaded rod is rotatably connected to the left side of the connecting plate. A moving plate is threaded to the outer wall of the one-way threaded rod. A sliding component 206 is provided at the bottom of the U-shaped clamping plate 201. A buffer component 207 is provided at the top center of the working surface 1.

[0034] Specifically, the working surface 1 serves as the operating platform for the entire testing device, providing an installation foundation and stable working plane for the clamping mechanism 2 and pressing mechanism 4, ensuring that the positions of each component are fixed during the testing process and that the testing operation can be carried out in an orderly manner. The clamping mechanism 2 is located at the top center of the working surface 1 specifically for fixing the test mold, preventing displacement or shaking of the mold during the pressing test, ensuring accurate testing position, and improving the accuracy of the test data. The clamping mechanism 2 is used to clamp the test mold. The bottom of the working surface 1 is equipped with a lifting mechanism 3 for raising and lowering the working surface 1. By adjusting the height of the working surface 1, it can adapt to the height of different operators and different testing scenarios. To meet the requirements of temperature control, the operating mechanism 1 allows operators to operate in a comfortable posture and also allows for adjustment of the test spacing in conjunction with the pressing mechanism 4. The top of the working surface 1 is equipped with a pressing mechanism 4 for pressing detection, which provides downward pressing force to push the testing mechanism 5 into contact with the test mold, thereby realizing the testing of the mold's performance. The bottom of the working surface 1 is equipped with a protective shell 6 to protect the internal structure of the supporting structure, enclosing the internal components of the lifting mechanism 3 to prevent external dust and impurities from entering and affecting the operation of the components, while also preventing operators from accidentally touching the internal moving parts, thus playing a dual role of safety protection and structural support. The clamping mechanism 2 includes a U-shaped clamping plate 201 with a U-shaped structure, which can clamp the mold from both sides and the top. It provides limiting and adapts to various test mold shapes, improving the versatility and stability of clamping. The bottom of the U-shaped clamping plate 201 is slidably connected to the top of the working surface 1, facilitating adjustment of the position of the U-shaped clamping plate 201 according to the mold size. A handle 202 is connected to the right side of the U-shaped clamping plate 201 to provide a force point for the operator, making it easy to manually push the U-shaped clamping plate 201 to slide on the working surface 1 and adjust the clamping position, making operation more convenient. Multiple connecting plates 203 are fixedly connected to the front and rear sides of the U-shaped clamping plate 201. A one-way threaded rod 204 is rotatably connected to the left side of the connecting plate 203. A moving plate 205 is threadedly connected to the outer wall of the one-way threaded rod 204. When the U-shaped clamping plate 201 is in use, the moving plate 205 can be adjusted to allow the clamping position to be adjusted. When the clamping plate 201 clamps the mold, the elasticity of the moving plate 205 allows for a tighter clamping. At the same time, when disassembling the mold, the resetting of the moving plate 205 assists the U-shaped clamping plate 201 to retract. The bottom of the U-shaped clamping plate 201 is provided with a sliding component 206 to reduce the frictional resistance between the U-shaped clamping plate 201 and the working surface 1, making the U-shaped clamping plate 201 slide more smoothly and reducing the force required by the operator when adjusting the position. The top middle of the working surface 1 is provided with a buffer component 207 to provide buffer protection for the mold during the placement and pressing of the test mold, avoiding direct rigid contact between the mold and the working surface 1, which could lead to damage. It can also reduce the impact force during pressing and protect the testing mechanism 5.

[0035] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3The lifting mechanism 3 includes a driving component 301, which is located at the bottom of the working surface 1. The output end of the driving component 301 is connected to a coupling 302, and the other end of the coupling 302 is connected to a bidirectional threaded rod 303. The outer wall of the bidirectional threaded rod 303 is threaded with two symmetrically distributed sliding plates 304. A diamond-shaped lifting rod 305 is rotatably connected between the adjacent sliding plates 304. The top of the diamond-shaped lifting rod 305 is provided with a vibration damping component 306. The vibration damping component 306 includes a limiting post 3062. The bottom of the limiting post 3062 is fixedly connected to the bottom of the inner wall of the protective shell 6. The outer wall of the limiting post 3062 is provided with a spring 3061, and the top of the limiting post 3062 is fixedly connected with a support plate 3063.

[0036] Specifically, the lifting mechanism 3 includes a drive component 301 as a lifting power source, providing driving force for the rotation of the bidirectional threaded rod 303. By controlling the forward and reverse rotation of the drive component 301, the working surface 1 can be raised and lowered. The drive component 301 is located at the bottom of the working surface 1. The output end of the drive component 301 is connected to a coupling 302 for connecting the output end of the drive component 301 and the bidirectional threaded rod 303. While transmitting power, it can compensate for installation deviations between the two, reduce vibration transmission, and protect the drive component 301 and the bidirectional threaded rod 303. The other end of the coupling 302... One end is connected to a bidirectional threaded rod 303. The rod body has threads on both sides with opposite directions of rotation. When rotated, it drives two sliding plates 304 to move simultaneously towards and away from each other, thereby controlling the opening and closing of the rhomboid lifting rod 305. Two symmetrically distributed sliding plates 304 are threadedly connected to the outer wall of the bidirectional threaded rod 303. These sliding plates slide under the influence of the bidirectional threaded rod 303, changing their positions to move the nodes of the rhomboid lifting rod 305, thus adjusting the height of the rhomboid lifting rod 305. The adjacent sliding plates 304 are rotatably connected to the rhomboid lifting rod 305, which employs a rhomboid telescopic structure. The overall height is adjusted by changing the opening and closing angle of the rhombus, thereby driving the working surface 1 to rise and fall. Its structure is stable and has a strong load-bearing capacity, ensuring a smooth lifting process for the working surface 1. The top of the rhombus lifting rod 305 is equipped with a vibration damping component 306 to absorb vibrations generated during the lifting process, preventing vibrations from being transmitted to the working surface 1 and affecting testing accuracy. Simultaneously, during pressure testing, it can also buffer the impact force generated by pressing, protecting the lifting mechanism 3. The vibration damping component 306 includes a limiting post 3062 that limits the extension and retraction direction of the spring 3061, preventing the spring 3061 from shifting laterally. To ensure precise vibration reduction, the bottom of the limiting post 3062 is fixedly connected to the bottom of the inner wall of the protective shell 6. The outer wall of the limiting post 3062 is equipped with a spring 3061, which absorbs vibration energy through elastic deformation to achieve vibration reduction. When impacted, the spring 3061 is compressed and buffered; after the impact disappears, the spring 3061 returns to its original position. The top of the limiting post 3062 is fixedly connected to a support plate 3063, which connects the diamond-shaped lifting rod 305 to the vibration reduction component 306, transmitting lifting force and support force, while increasing the contact area with the working surface 1, making the support more stable.

[0037] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4The sliding component 206 includes a square groove 2061, which is formed at the bottom of the U-shaped clamping plate 201. A slide rail 2062 is slidably connected to the inner wall of the square groove 2061. The bottom of the slide rail 2062 is fixedly connected to the top of the working surface 1. The buffer component 207 includes a cylindrical sleeve 2071, which is fixedly connected to the top of the working surface 1. A second spring 2072 is provided inside the cylindrical sleeve 2071. A sliding column 2073 is fixedly connected to the top of the second spring 2072. The outer wall of the sliding column 2073 is slidably connected to the inner wall of the cylindrical sleeve 2071. A second connecting plate 2074 is fixedly connected to the top of the sliding column 2073.

[0038] Specifically, the sliding assembly 206 includes a square groove 2061 formed at the bottom of the U-shaped clamping plate 201, providing space for the slide rail 2062 to ensure that the U-shaped clamping plate 201 can be stably mounted on the slide rail 2062. The square groove 2061 is formed at the bottom of the U-shaped clamping plate 201, and the inner wall of the square groove 2061 is slidably connected to the slide rail 2062, which cooperates with the square groove 2061 to form a sliding guide structure, limiting the sliding trajectory of the U-shaped clamping plate 201 so that it can only move along the direction of the slide rail 2062, ensuring accurate adjustment of the clamping position. The bottom of the slide rail 2062 is fixedly connected to the top of the working surface 1. The buffer assembly 207 includes a cylindrical sleeve 2071 to provide installation space for the spring 2072 and the sliding column 2073, limiting the sliding direction of the sliding column 2073. The bottom is fixedly connected to the top of the working surface 1. The cylindrical sleeve 2071 is equipped with a second spring 2072 to provide buffering force. When the mold is placed on the second connecting plate 2074, the second spring 2072 is compressed to absorb the pressure and prevent the mold from being damaged. During the press test, it can also help to relieve the impact force. The top of the second spring 2072 is fixedly connected to a sliding column 2073, which slides along the inner wall of the cylindrical sleeve 2071 under the drive of the second spring 2072 to transmit the buffering force and support the second connecting plate 2074. The outer wall of the sliding column 2073 is slidably connected to the inner wall of the cylindrical sleeve 2071. The top of the sliding column 2073 is fixedly connected to the second connecting plate 2074, which directly contacts the test mold, increasing the contact area between the mold and the buffer component 207, so that the buffering force is evenly transmitted to the mold and avoiding excessive local force that could damage the mold.

[0039] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5The pressing mechanism 4 includes a fixed frame 401, the bottom of which is fixedly connected to the top of the working surface 1. A push rod 402 is fixedly connected to the top of the fixed frame 401. A pressing plate 403 is connected to the bottom of the push rod 402. An elastic component 404 is provided at the bottom of the pressing plate 403. The elastic component 404 includes multiple limiting posts 4041. The outer walls of the multiple limiting posts 4041 are slidably connected to the bottom of the pressing plate 403. A spring 4042 is provided on the outer wall of the limiting posts 4041. A testing mechanism 5 is provided at the bottom of the limiting posts 4041. The testing mechanism 5 includes a testing plate 501, the top of which is fixedly connected to the bottom of the multiple limiting posts 4041. Multiple testing posts 502 are fixedly connected to the bottom of the testing plate 501. A signal line 7 for transmitting signals is connected to the right side of the pressing plate 403. The other end of the signal line 7 is connected to a processing center 8. A display screen 9 is provided on the front side of the processing center 8.

[0040] Specifically, the pressing mechanism 4 includes a fixed frame 401 as a support frame for the pressing mechanism 4, which fixes the push rod 402 and pressing plate 403 components above the working surface 1 to ensure accurate positioning of each component. The bottom of the fixed frame 401 is fixedly connected to the top of the working surface 1, and the top of the fixed frame 401 is fixedly connected to the push rod 402 to provide power for pressing. The pressing plate 403 can be pushed downward by hydraulic, pneumatic, or electric means to output a stable pressing force to meet the pressure requirements of different tests. The bottom of the push rod 402 is connected to the pressing plate 403 to evenly transmit the pressing force of the push rod 402 to the elastic component 404 and the testing mechanism 5, ensuring that the pressing of the mold by the testing mechanism 5 is more uniform. The bottom of the pressing plate 403 is equipped with... The elastic component 404 provides elastic cushioning during pressing, preventing excessive pressing force from directly damaging the test mold and test mechanism 5. It also allows the test post 502 to fit more closely to the mold surface, improving testing results. The elastic component 404 includes multiple limiting posts 4041 that limit the extension and retraction of the spring 4042, preventing the spring 4042 from shifting and ensuring the elastic force is vertically downward. It also connects the pressing plate 403 to the test mechanism 5, transmitting the pressing force. The outer walls of the multiple limiting posts 4041 are slidably connected to the bottom of the pressing plate 403. The outer walls of the limiting posts 4041 are equipped with springs 4042, which provide cushioning through elastic deformation. During pressing, the springs 4042 compress, absorbing excess pressure; after pressing, the springs 4042 release their elasticity. 4042 resets, causing the testing mechanism 5 to retract. The bottom of the limiting post 4041 is equipped with the testing mechanism 5, which directly contacts the test mold to perform specific testing operations. The testing mechanism 5 includes a test plate 501 that fixes multiple test posts 502, ensuring the precise position and neat arrangement of the test posts 502. At the same time, it evenly distributes the pressing force transmitted by the elastic component 404 to each test post 502. The top of the test plate 501 is fixedly connected to the bottom of the multiple limiting posts 4041. The bottom of the test plate 501 is fixedly connected to multiple test posts 502. Designed according to testing requirements, these posts are inserted into and press specific positions on the mold to test the mold's hardness, strength, and sealing performance. Some test posts 502 can integrate sensors to collect test data. The right side of the pressing plate 403 is connected to a signal line 7 for transmitting signals, which transmits the test data collected by the testing mechanism 5 to the processing center 8. At the same time, it can also transmit control signals from the processing center 8 to realize the automated control of the device. The other end of the signal line 7 is connected to the processing center 8, which serves as the control and data processing core of the device. It receives the test data transmitted by the signal line 7, analyzes and calculates it, and generates a test report. It can also control the operation of the push rod 402 and the drive component 301. The front of the processing center 8 is equipped with a display screen 9, which displays the test data analyzed by the processing center 8, the equipment operating status, and the test report information in a visual manner, so that operators can view the test status in real time and adjust the operating parameters in a timely manner.

[0041] Working principle: First, pull the handle 202. The handle 202 moves outward, causing the U-shaped clamping plate 201 to move outward as well. Simultaneously, the U-shaped clamping plate 201 causes the connecting plate 203 to slide along the outer wall of the one-way threaded rod 204. At the same time, the moving plate 205 is stretched, causing the square groove 2061 on the handle 202 to slide along the outer wall of the slide rail 2062. Then, the mold to be tested is placed on the connecting plate 2074. The connecting plate 2074 then causes the sliding column 2073 to move downward, simultaneously compressing the spring 2074. 072 deforms the mold, and the sliding column 2073 slides along the inner wall of the cylindrical sleeve 2071. Then, the pull handle 202 is released, and under the action of the moving plate 205, the U-shaped clamping plate 201 will hold the mold. At this time, the push rod 402 is activated, and then the push rod 402 drives the pressing plate 403 to move downward, so that the test column 502 on the test plate 501 contacts the test mold. Then, the detected stress data will be transmitted to the processing center 8 through the signal line 7 and displayed on the display screen 9, realizing the function of testing molds of different sizes.

[0042] When the height of the working surface 1 needs to be adjusted, the drive unit 301 is activated. At this time, the drive unit 301 will drive the coupling 302 to rotate, and the coupling 302 will drive the double-threaded rod 303 to rotate, pushing the sliding plate 304 to slide along the outer wall of the double-threaded rod 303. At the same time, the sliding plate 304 will press and stretch the diamond-shaped lifting rod 305 inward, causing the height of the diamond-shaped lifting rod 305 to change. This will also cause the height of the support plate 3063 to change. Meanwhile, the spring 3061 and the limiting post 3062 will buffer the whole, realizing the adjustment of the height of the working surface 1, which is convenient for the operator.
