Description

Technical Field

[0001] This utility model relates to the field of metal mold technology, specifically a metal mold testing fixture. Background Technology

[0002] Metal molds are tools used to process metal or other materials into products of specific shapes through processes such as pressure processing and injection molding. Classified by process application, common types include die casting molds, injection molds, and stamping molds. Testing is required during the production and processing of metal molds.

[0003] However, existing technologies still have the following problems:

[0004] Existing metal mold testing fixtures are mostly poorly versatile, often customized for specific molds, and difficult to adapt to even slight changes in mold specifications. Enterprises need to prepare a large number of fixtures, which is costly and cumbersome for mold replacement and debugging, thus delaying progress. The positioning accuracy also needs to be improved, as displacement can easily lead to data fluctuations and affect mold evaluation.

[0005] To address the aforementioned problems, the inventors proposed a metal mold testing fixture to solve them. Utility Model Content

[0006] In order to solve the problem of poor versatility of metal mold testing fixtures, the purpose of this utility model is to provide a metal mold testing fixture.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: a metal mold testing fixture, including a base plate, two carrier plates symmetrically and slidably disposed on the upper surface of the base plate, two support blocks and a motor fixedly disposed on the inner side of the carrier plates, and a bidirectional lead screw rotatably disposed between the two support blocks, two moving blocks slidably disposed on the inner side of the carrier plates, and a limiting rod fixedly disposed between the two moving blocks, the output end of the motor passing through the support blocks and fixedly connected to the bidirectional lead screw, two locking blocks being sleeved on the outer surfaces of the bidirectional lead screw and the limiting rod, and two of the locking blocks being threadedly connected to the bidirectional lead screw, and a sleeve and a post being disposed between the two corresponding locking blocks.

[0008] Preferably, uprights are symmetrically fixed on the upper surface of the base plate, and limiting posts are fixed between the uprights on one side. Limiting blocks are symmetrically fixed on both sides of the carrier plate, and the limiting blocks are movably sleeved on the corresponding limiting posts.

[0009] Preferably, one end of the sleeve is fixedly connected to the locking block, and the other end of the sleeve is movably connected to the insert post. The end of the insert post away from the sleeve is fixedly connected to the corresponding locking block. The insert post and the corresponding sleeve are connected by bolts, and both the insert post and the sleeve have several bolt grooves distributed at equal intervals.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model uses a motor-driven bidirectional lead screw to adjust the spacing of the clamping blocks. Combined with a telescopic sleeve and insert structure, it can flexibly adapt to metal molds of different sizes and specifications.

[0018] 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.

[0019] Example: Figure 1-4As shown, this utility model provides a metal mold testing fixture, including a base plate 1. Two carrier plates 3 are symmetrically slidably disposed on the upper surface of the base plate 1. Two support blocks 31 and a motor 35 are fixedly disposed on the inner side of the carrier plate 3. A protective plate is fixedly connected between the motor 35 and the carrier plate 3, and the protective plate provides protection and support for the motor 35. A bidirectional lead screw 33 is rotatably disposed between the two support blocks 31. Two moving blocks 32 are slidably disposed on the inner side of the carrier plate 3. A T-shaped groove 37 is symmetrically opened on one side of the carrier plate 3. A T-shaped slider 38 is fixedly disposed on the side of the moving block 32 near the carrier plate 3, and the T-shaped slider 38 is engaged in the T-shaped groove 37. A limiting rod 34 is fixed between the two moving blocks 32. The output end of the motor 35 passes through the support block 31 and is fixedly connected to the bidirectional lead screw 33. Two locking blocks 36 are sleeved on the outer surfaces of the bidirectional lead screw 33 and the limiting rod 34. There are four locking blocks 36 on one of the carrier plates 3, and the four locking blocks 36 are distributed in a mirror image. Two of the locking blocks 36 are threadedly connected to the bidirectional lead screw 33. A sleeve 4 and a post 41 are provided between the two corresponding locking blocks 36. When conducting the metal mold opening and closing test, the metal mold is first placed stably on the carrier plate 3, and the motor 35 is started. The output end of the motor 35 drives the bidirectional lead screw 33 to rotate. Based on the principle of threaded transmission, the locking block 36 threadedly connected to the bidirectional lead screw 33 will move precisely in opposite directions or in opposite directions under the auxiliary guidance of the limiting rod 34. Since the two moving blocks 32 maintain the stability of linear motion through the limiting rod 34, and their T-shaped slider 38 slides smoothly in the T-shaped groove 37 of the carrier plate 3, the smoothness and accuracy of the movement of the locking block 36 are further ensured.

[0020] One end of the sleeve 4 is fixedly connected to the locking block 36, and the other end of the sleeve 4 is movably inserted into the insertion post 41. The end of the insertion post 41 away from the sleeve 4 is fixedly connected to the corresponding locking block 36. A groove 42 is provided inside the sleeve 4, and a slide bar 43 is fixedly provided on the outer surface of the insertion post 41. The slide bar 43 is locked in the groove 42. The insertion post 41 and the corresponding sleeve 4 are connected by bolts. Several bolt grooves 44 are provided on both the insertion post 41 and the sleeve 4 at equal intervals. As the locking block 36 moves, the overall position of the sleeve 4 and the insertion post 41 connected between the locking blocks 36 changes. The insertion post 41 can slide flexibly along the groove 42 inside the sleeve 4 to adapt to the change in the spacing of the locking blocks 36. After adjusting to the appropriate position, the bolts pass through the corresponding bolt grooves 44 to lock the insertion post 41 and the sleeve 4, thereby enabling the components on the two carrier plates 3 to work together to accurately clamp and position metal molds of different sizes.

[0021] The lower surface of the carrier plate 3 is movably fitted to the base plate 1. Uprights 2 are symmetrically fixed to the upper surface of the base plate 1, and limiting posts 21 are fixed between the uprights 2 on one side. Limiting blocks 22 are symmetrically fixed to both sides of the carrier plate 3, and the limiting blocks 22 are movably fitted onto the corresponding limiting posts 21. Then, the closing process of the metal mold is simulated by the approaching movement of the two carrier plates 3, observing the fit of various components during mold closing, such as the tightness of the parting surface and the smoothness of the guiding mechanism. The reverse movement of the carrier plates 3 simulates the opening... During the mold opening process, check whether the mold opening is smooth, whether the ejection system can work normally, and whether there is any abnormal interference in the internal structure of the mold during the opening and closing action. The sliding direction of the carrier plate 3 on the base plate 1 is controlled by the upright 2, the limiting post 21, and the limiting block 22. The limiting block 22 is tightly fitted on the limiting post 21 to ensure that the carrier plate 3 can only run stably along the preset straight trajectory. It can be pushed and pulled by hand, which is convenient and reliable. It provides a reliable basic support for the mold opening and closing test and avoids the accuracy of the test results being affected by the displacement of the carrier plate position.

[0022] Working principle: When conducting the opening and closing test of the metal mold, the metal mold is first placed stably on the carrier plate 3, and the motor 35 is started. The output end of the motor 35 drives the bidirectional lead screw 33 to rotate. Based on the principle of threaded transmission, the locking block 36 threadedly connected to the bidirectional lead screw 33 will move precisely in opposite directions or in opposite directions under the auxiliary guidance of the limiting rod 34. Since the two moving blocks 32 maintain the stability of linear motion through the limiting rod 34, and their T-shaped sliders 38 slide smoothly in the T-shaped grooves 37 of the carrier plate 3, the stability and accuracy of the movement of the locking block 36 are further ensured.

[0023] As the locking block 36 moves, the overall position of the sleeve 4 and the insert 41 connected between the locking blocks 36 changes. The insert 41 can slide flexibly along the groove 42 inside the sleeve 4 to adapt to the change in the spacing of the locking blocks 36. After being adjusted to the appropriate position, the insert 41 and the sleeve 4 are locked by bolts passing through the corresponding bolt grooves 44, so that the components on the two carrier plates 3 work together to accurately clamp and position metal molds of different sizes.

[0024] Then, the closing process of the metal mold is simulated by the approaching movement of the two carrier plates 3. The cooperation of each component during mold closing is observed, such as the tightness of the parting surface and the smoothness of the guiding mechanism. The reverse movement of the carrier plates 3 simulates the mold opening process, checking whether the mold opening is smooth, whether the ejection system can work normally, and whether there is any abnormal interference in the internal structure of the mold during the opening and closing action. The sliding of the carrier plate 3 on the base plate 1 is controlled by the upright 2, the limiting post 21, and the limiting block 22. The limiting block 22 is tightly fitted on the limiting post 21, ensuring that the carrier plate 3 can only run stably along the preset straight trajectory. It can be pushed and pulled by hand, which is convenient and reliable. It provides a reliable basic support for the mold opening and closing test and avoids the accuracy of the test results due to the positional deviation of the carrier plate.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
