Description

Technical Field

[0001] This utility model relates to the field of casting and processing technology, and more specifically, to a vibration compaction platform for a mold to be cast. Background Technology

[0002] In industrial fields such as metal casting and composite material molding, the problem of residual air bubbles in molten material during mold casting has long constrained the improvement of product quality. Traditional vibration defoaming technology often suffers from complex vibration energy transmission paths and significant impact force attenuation, making it difficult to form uniform high-frequency micro-amplitude oscillations inside the mold. In particular, it is not effective in eliminating air bubbles in high-viscosity materials or molds with complex structures.

[0003] Existing equipment generally adopts a rigid impact structure, which makes it difficult to dynamically match the vibration frequency with the material properties. It also lacks an effective energy storage and instantaneous release mechanism, which can easily lead to problems such as low vibration energy utilization and discontinuous impact waveform. In addition, conventional vibration platforms cannot achieve coordinated control of vibration frequency and impact energy. During operation, it is necessary to rely on manual experience to repeatedly adjust parameters, which affects production efficiency and makes it difficult to ensure the quality stability of different batches of products. Therefore, in order to address the above technical problems, a vibration compaction platform for the mold to be poured is proposed here. Utility Model Content

[0004] The purpose of this invention is to provide a vibration compaction platform for a mold to be poured. It stores energy through a symmetrical sliding compression spring and flexibly pulls the mold away from the vibration block. After the block is released, the spring resets and triggers a high-speed impact, generating transient impact vibration that forces the air bubbles in the material to be sheared and broken. This allows for precise control of high-frequency vibration energy, ensuring efficient defoaming and mold stability, and significantly improving the density of the pouring.

[0005] This utility model is achieved through the following technical solution:

[0006] A vibration compaction platform for a mold to be poured includes a platform body, a support plate fixedly connected to the inner side of the platform body, a mounting base fixedly connected to the upper side of the support plate, a groove for placing the mold on the upper side of the mounting base, fixed cylinders fixedly connected between the two sides of the mounting base and the platform body, a vibration mechanism installed inside the fixed cylinder, two sets of centrally symmetrically arranged L-plates slidably connected to the inner side of the platform body, a connecting plate fixedly connected to the outer side of the L-plates, a connecting rope fixedly connected to the outer side of the connecting plate, and a deflection mechanism installed at the geometric center of the bottom inner side of the platform body.

[0007] Preferably, the vibration mechanism includes a vibration block and a first compression spring. The vibration block is slidably connected to the inner side of the fixed cylinder, the first compression spring is fixedly connected to one side of the vibration block, and the other end of the first compression spring is fixedly connected to the inner side of the platform body. The end of the vibration block abuts against the outside of the mounting base.

[0008] Preferably, the inner bottom of the platform body is provided with two sets of centrally symmetrical sliding grooves, the bottom of the L plate is fixedly connected to a sliding plate, and the sliding plate is slidably connected to the inner side of the sliding groove. The inside of the sliding groove is fixedly connected to a second compression spring, and the end of the second compression spring is fixedly connected to one side of the sliding plate.

[0009] Preferably, the end of the connecting rope passes through the outside of the platform body and is fixedly connected to one side of the vibrating block through the inside of the fixing cylinder, and the first compression spring is sleeved on the outside of the connecting rope.

[0010] Preferably, the deflection mechanism includes a rotating shaft and a rotating plate. The rotating shaft is rotatably connected to the bottom of the platform body, and the rotating plate is fixedly connected to the outside of the rotating shaft. There are two sets of rotating plates arranged symmetrically, and the rotating plates abut against the L-plate.

[0011] Preferably, a drive motor is fixedly connected to the bottom of the platform body, and the rotating shaft is fixedly connected to the drive motor.

[0012] Preferably, the two sets of L-plates and the two sets of sliding grooves are arranged and installed in a centrally symmetrical manner around the rotation axis.

[0013] Preferably, the bottom of the platform body is fixedly connected with four sets of support legs arranged in an array.

[0014] The technical solution of this utility model has at least the following beneficial effects:

[0015] This invention proposes a vibration compaction platform for a mold to be poured. Through the alternating action of rotational thrust and elastic energy storage, regular high-frequency vibration is generated. This drives a symmetrical sliding component to compress a spring, which stores energy and then releases it instantaneously. This causes the vibrating block to impact at high speed, generating a transient shock wave. This shock wave penetrates the mold, inducing uniform micro-oscillations within the molten material. This causes bubbles to burst and escape due to shear fluctuations. The vibration frequency is linearly adjusted with the rotational speed. Combined with the dynamic matching of spring stiffness and material properties, it ensures that fluids of different viscosities receive optimal defoaming energy. The symmetrical layout balances the impact force distribution, and flexible traction reduces motion friction loss and eliminates vibration distortion. The bottom array support disperses the vibration transmission path and suppresses external resonance interference. Compared to traditional rigid impact methods, this platform offers advantages such as high energy utilization, continuous and stable waveforms, and intuitive parameter adjustment. It significantly improves the efficiency of bubble removal within complex molds, ensures the density of the poured product, and meets the requirements of high-precision molding.

Detailed Implementation

[0024] 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.

[0025] Please see Figures 1-7 The present invention proposes a vibration platform for a mold to be poured, comprising a platform body 1, a support plate 2 fixedly connected to the inner side of the platform body 1, a mounting base 3 fixedly connected to the upper side of the support plate 2, a groove for placing the mold on the upper side of the mounting base 3, a fixing cylinder 4 fixedly connected between the two sides of the mounting base 3 and the platform body 1, a vibration mechanism installed inside the fixing cylinder 4, two sets of centrally symmetrically arranged L plates 7 slidably connected to the inner side of the platform body 1, a connecting plate 11 fixedly connected to the outside of the L plates 7, a connecting rope 12 fixedly connected to the outside of the connecting plate 11, and a deflection mechanism installed at the geometric center of the bottom inner side of the platform body 1.

[0026] The vibration mechanism includes a vibration block 5 and a first compression spring 6. The vibration block 5 is slidably connected to the inner side of the fixed cylinder 4, and the first compression spring 6 is fixedly connected to one side of the vibration block 5. The other end of the first compression spring 6 is fixedly connected to the inner side of the platform body 1, and the end of the vibration block 5 abuts against the outside of the mounting base 3. Under the action of the first compression spring 6, the vibration block 5 can reciprocate to impact the mounting base 3, generating high-frequency vibration to eliminate air bubbles in the mold.

[0027] The inner bottom of the platform body 1 has two sets of centrally symmetrically arranged sliding grooves 8. The bottom of the L-plate 7 is fixedly connected to a sliding plate 9, which is slidably connected to the inner side of the sliding groove 8. A second compression spring 10 is fixedly connected inside the sliding groove 8, and the end of the second compression spring 10 is fixedly connected to one side of the sliding plate 9. When the sliding plate 9 slides in the sliding groove 8, it compresses the second compression spring 10, providing elastic potential energy for subsequent reset.

[0028] The end of the connecting rope 12 passes through the outside of the platform body 1 and is fixedly connected to one side of the vibrating block 5 through the inside of the fixing cylinder 4, and the first compression spring 6 is sleeved on the outside of the connecting rope 12. The flexible traction of the connecting rope 12 ensures that the movement of the vibrating block 5 is precisely linked with the displacement of the L plate 7.

[0029] The deflection mechanism includes a rotating shaft 14 and a rotating plate 15. The rotating shaft 14 is rotatably connected to the bottom of the platform body 1, and the rotating plate 15 is fixedly connected to the outside of the rotating shaft 14. There are two sets of rotating plates 15 arranged symmetrically, and the rotating plates 15 abut against the L plate 7. The rotation of the rotating plate 15 pushes the L plate 7 to slide, thereby triggering periodic vibration.

[0030] A drive motor 13 is fixedly connected to the bottom of the platform body 1, and the rotating shaft 14 is also fixedly connected to the drive motor 13. The drive motor 13 provides stable power to ensure that the rotating shaft 14 rotates at a uniform speed to achieve regular vibration.

[0031] The two sets of L-plates 7 and the two sets of sliding grooves 8 are all arranged symmetrically around the rotation axis 14. The symmetrical design ensures the balanced distribution of vibration force and avoids the impact of eccentric load on the compaction effect.

[0032] The bottom of the platform body 1 is fixedly connected with four arrayed support feet 16. The arrayed arrangement of the support feet 16 disperses vibration transmission, avoids external resonance interference, and further ensures the stability of the compaction process.

[0033] The working principle of a vibration compaction platform for a mold to be poured, based on an embodiment, is as follows: First, the mold is precisely embedded into the groove of the mounting base 3, and the gap between the mold and the groove is fixed by filling iron sheets to ensure that the mold does not shift during vibration. After the pouring material is injected, the drive motor 13 is started and drives the rotating shaft 14 to rotate at a constant speed. Then, the symmetrically installed rotating plates 15 rotate accordingly. When the outer edge of the rotating plate 15 contacts the L-plates 7 symmetrically distributed inside the platform body 1, its rotational thrust forces the two sets of L-plates 7 to slide synchronously towards the center of the platform along the slide groove 8. During this process, the sliding plate 9 at the bottom of the L-plate 7 compresses the second compression spring 10 in the slide groove 8. At the same time, the connecting plate 11 on the outside of the L-plate 7 pulls the vibrating block 5 in the fixed cylinder 4 to overcome the resistance of the first compression spring 6 and move outward through the flexible connecting rope 12, so that the vibrating block 5 is disengaged from the mounting base 3. At this time, both sets of compression springs are in an elastic potential energy storage state. As the rotating shaft 14 continues to rotate... As the rotating plate 15 rotates, the contact surface between it and the L-plate 7 gradually separates. The elastic restoring force of the second compression spring 10 pushes the slide plate 9 and the L-plate 7 back to their original positions quickly. At the same time, the tension of the connecting rope 12 decreases sharply. The first compression spring 6 drives the vibrating block 5 to strike the side wall of the mounting base 3 at high speed, generating transient impact vibration. This vibration is transmitted to the mold through the mounting base 3, causing the internal molten material to oscillate at high frequency due to inertia. During the oscillation, bubbles are broken by shear force or float to the liquid surface and dissipate. In this way, the driving motor 13 continues to operate, and the rotating plate 15 completes one cycle of pushing away and releasing the L-plate 7 every half rotation, thus forming a regular high-frequency impact of the vibrating block 5 on the mounting base 3. By adjusting the speed of the driving motor 13, the vibration frequency can be precisely controlled. With the optimization of the stiffness parameters of the second compression spring 10, the vibration energy is matched with the material characteristics inside the mold, ultimately achieving efficient elimination of bubbles and effectively improving the quality of the cast product.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
