Description

Technical Field

[0001] This utility model relates to the field of support structure technology, specifically a floating flexible support structure for injection molds. Background Technology

[0002] Injection molding, as an important plastic molding method, occupies a pivotal position in modern manufacturing. It is widely used in numerous fields such as automobiles, electronics, home appliances, and medical devices to produce plastic products with complex shapes and high precision requirements. As the core component of injection molding, the performance and quality of the injection mold directly affect the quality of the plastic products, production efficiency, and cost.

[0003] When injection molds are used, they are usually supported on a bracket. However, the lack of a direct positioning and fixing structure causes the injection mold to shift during use. In terms of mold installation and adaptation, the mounting components of existing support structures are often of fixed dimensions, which cannot be flexibly adjusted according to different mold body specifications, resulting in extremely poor versatility. Furthermore, the rigid connection between the mold and the bracket makes the lower mold platen lack flexibility under stress, and it cannot adaptively adjust according to the stress conditions. During demolding, because the lower mold platen is fixed, it will be subjected to a large impact force at the moment of demolding, which can easily lead to damage to the lower mold platen and greatly shorten the service life of the mold. Therefore, this utility model provides a floating flexible support structure for injection molds. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a floating flexible support structure for injection molds. This solves the problem that existing support structures, which typically mount on supports without a direct positioning and fixing structure, cause mold misalignment during use. Furthermore, the mounting components of existing support structures are often of fixed dimensions, making them unsuitable for flexible adjustment to different mold body sizes, resulting in extremely poor versatility. Additionally, the rigid connection between the mold and the support means the lower mold platen lacks flexibility under stress and cannot adaptively adjust to different load conditions. During demolding, because the lower mold platen is fixed, it experiences significant impact forces at the moment of demolding, easily leading to damage and greatly shortening the mold's lifespan.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a floating flexible support structure for injection molds, comprising a mounting base, wherein the mounting base is provided with a support mechanism for mounting the injection mold, the support mechanism comprising:

[0006] The shock absorption assembly includes a support housing fixed to the upper end of the mounting base, and a support block connected by a buffer assembly is provided inside the support housing;

[0007] The mounting assembly includes a mounting groove on the upper surface of a support block, a sliding groove inside the mounting groove, a mounting bracket connected by a threaded assembly inside the sliding groove, a pair of reinforcing blocks fixed at the upper end of the mounting bracket, and a limiting plate connected by an opening and closing assembly inside the mounting bracket.

[0008] Preferably, the mounting base has a trapezoidal structure, and the lower end face of the mounting base is larger than the upper end face, and a rubber pad is fixed to the lower end face of the mounting base.

[0009] Preferably, the mold body is placed inside the mounting groove, and the size of the mounting groove is larger than that of the mold body.

[0010] Preferably, the buffer assembly includes damping springs evenly distributed on the upper surface of the mounting base, a support block fixedly connected to the upper end of the damping springs, a damping rod provided on the inner ring of the damping springs, and the lower end of the damping rod fixedly connected to the mounting base, and the support block slidably connected to the inner wall of the support housing.

[0011] Preferably, the threaded assembly includes a bidirectional screw rotatably connected inside a groove, a pair of sliders slidably connected to the inner wall of the groove, the sliders being threadedly connected to the bidirectional screw, and a mounting bracket fixedly connected to the upper end of the sliders, the mounting bracket having a U-shaped structure.

[0012] Preferably, the opening and closing assembly includes a guide groove inside the upper end of the mounting bracket, one end of the limiting plate is located inside the guide groove and is slidably connected, the limiting plate is configured in two sets, and the clamping surface of the limiting plate is provided with a rubber layer.

[0013] Beneficial effects

[0014] This invention provides a floating flexible support structure for injection molds. Compared with the prior art, it has the following advantages:

[0015] Firstly, this utility model, by adjusting the position of the mounting bracket and the limiting plate, can adapt to mold bodies of different sizes, thus improving the versatility of the support structure. The reinforcing block increases the contact area between the mounting bracket and the side wall of the mold body, enhancing the stability of clamping. The clamping surface of the limiting plate is provided with a rubber layer, which can not only prevent wear on the mold body during clamping but also increase friction, further improving the clamping effect. Furthermore, the opening and closing of the mounting bracket and the limiting plate facilitates quick positioning and disassembly of the mold body, improving the efficiency of mold installation and maintenance. Finally, the mounting bracket and the limiting plate ensure the fixed installation of the injection mold, ensuring stability during operation.

[0016] Secondly, the shock absorption component of this utility model can effectively absorb the vibration generated during the operation of the injection mold, reduce the impact of vibration on the mold itself and surrounding equipment, and extend the service life of the mold. The damping support rod and the shock absorption spring are used together to avoid excessive rebound of the shock absorption spring and improve the stability of the shock absorption effect. The sliding connection between the support block and the inner wall of the support shell ensures the stability of the movement trajectory of the support block during vibration and avoids deviation.

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a floating flexible support structure for injection molds, including a mounting base 1, on which a support mechanism for mounting the injection mold is provided, the support mechanism including:

[0024] The shock absorption assembly includes a support housing 2 fixed at the upper end of the mounting base 1, and a support block 201 connected by a buffer assembly is provided inside the support housing 2.

[0025] The mounting assembly includes a mounting groove 202 on the upper surface of a support block 201, a sliding groove 3 inside the mounting groove 202, a mounting bracket 303 connected by a threaded assembly inside the sliding groove 3, a pair of reinforcing blocks 4 fixed at the upper end of the mounting bracket 303, and a limiting plate 305 connected by an opening and closing assembly inside the mounting bracket 303.

[0026] In a preferred embodiment, the mounting base 1 has a trapezoidal structure, and the lower end face of the mounting base 1 is larger than the upper end face. A rubber pad 5 is fixed to the lower end face of the mounting base 1. The trapezoidal structure of the mounting base 1 lowers the center of gravity of the entire structure, improves stability, and makes it less prone to tipping over. The rubber pad 5 can not only increase the friction with the placement surface and prevent the support structure from sliding during operation, but also play a certain role in shock absorption and buffering, reducing the transmission of vibration to the placement surface.

[0027] In a preferred embodiment, a mold body 203 is placed inside the mounting groove 202. The size of the mounting groove 202 is larger than that of the mold body 203. The threaded assembly includes a bidirectional screw 301 rotatably connected inside the slide groove 3. A pair of sliders 302 are slidably connected to the inner wall of the slide groove 3. The sliders 302 are threadedly connected to the bidirectional screw 301. The mounting bracket 303 is fixedly connected to the upper end of the sliders 302. The mounting bracket 303 has a U-shaped structure. The opening and closing assembly includes a guide groove 304 opened inside the upper end of the mounting bracket 303. One end of the limiting plate 305 is slidably connected inside the guide groove 304. The limiting plate 305 is configured in two sets. The clamping surface of the limiting plate 305 is provided with a rubber layer.

[0028] The reinforcing block 4 increases the contact area between the mounting bracket 303 and the side wall of the mold body 203, thereby increasing the stability of the clamping.

[0029] The guide groove 304 is equipped with a bidirectional screw that is threadedly connected to the two sets of limiting plates 305, which is used to drive the opening and closing of the two sets of limiting plates 305.

[0030] When installing the mold, first place the mold body 203 in the mounting groove 202, and then rotate the bidirectional screw 301. Since the slider 302 is threadedly connected to the bidirectional screw 301 and slides in the slide groove 3, the rotation of the bidirectional screw 301 will drive a pair of sliders 302 to move closer to each other, thereby causing the mounting bracket 303 at the upper end of the slider 302 to move closer to the mold body 203 until the reinforcing block 4 contacts the side wall of the mold body 203. Then, the opening and closing assembly causes the limiting plate 305 to slide in the guide groove 304, so that the two sets of limiting plates 305 clamp and limit the mold body 203, thus completing the installation and fixing of the mold.

[0031] In a preferred embodiment, the buffer assembly includes damping springs 6 evenly distributed on the upper surface of the mounting base 1, a support block 201 fixedly connected to the upper end of the damping springs 6, a damping rod 601 provided on the inner ring of the damping springs 6, and the lower end of the damping rod 601 fixedly connected to the mounting base 1. The support block 201 is slidably connected to the inner wall of the support housing 2. When the injection mold is demolded, since the lower mold plate is fixed, it will be subjected to a large impact force at the moment of demolding. The mold body 203 will transmit the vibration force to the support block 201. After being subjected to the vibration force, the support block 201 will slide up and down along the inner wall of the support housing 2. At this time, the damping springs 6 connected to the lower end of the support block 201 will undergo elastic deformation and absorb part of the vibration force through the extension and contraction movement. At the same time, the damping rod 601 will generate damping force during the extension and contraction of the damping springs 6, which will reduce the vibration speed and amplitude of the support block 201, thereby realizing the damping and buffering effect on the mold and avoiding damage to the mold by strong pressure.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] When installing the floating flexible support structure for the injection mold, first place the mold body 203 in the mounting groove 202 opened on the upper end face of the support block 201, which is larger than the mold body 203;

[0034] Next, rotate the bidirectional screw 301 rotatably connected inside the slide groove 3. Since the slider 302 is threadedly connected to the bidirectional screw 301 and slides on the inner wall of the slide groove 3, the rotation of the bidirectional screw 301 drives a pair of sliders 302 to move closer to each other, so that the U-shaped mounting bracket 303 fixedly connected to the upper end of the slider 302 moves closer to the mold body 203 until the pair of reinforcing blocks 4 fixed at the upper end of the mounting bracket 303 contacts the side wall of the mold body 203. Then, rotate the bidirectional screw threadedly connected to two sets of limiting plates 305 in the guide groove 304 inside the upper end of the mounting bracket 303, drive the two sets of limiting plates 305 to slide in the guide groove 304, so that the clamping surface of the limiting plate 305 has a rubber layer to clamp and limit the mold body 203, thus completing the mold installation and fixing.

[0035] When the injection mold is demolded, since the lower mold plate is fixed, it will be subjected to a large impact force at the moment of demolding. The mold body 203 transmits the vibration force to the support block 201. After being subjected to the vibration force, the support block 201 slides up and down along the inner wall of the support shell 2. At this time, the damping springs 6 evenly distributed at the lower end of the support block 201 undergo elastic deformation and absorb part of the vibration force through the extension and retraction movement. At the same time, the damping support rod 601 set in the inner ring of the damping spring 6 and fixedly connected to the mounting base 1 generates damping force during the extension and retraction of the damping spring 6, which reduces the vibration speed and amplitude of the support block 201, realizes the shock absorption and buffering of the mold, and avoids the strong pressure from damaging the mold.
