Description

Technical Field

[0001] This utility model belongs to the field of EPP foam product manufacturing technology, and specifically relates to a mold changing device for EPP foam material. Background Technology

[0002] With the increasingly widespread application of EPP materials in the automotive, packaging, and construction industries, the market demand for EPP foam products in terms of variety and specifications is also becoming more diversified. This requires foaming equipment to be able to quickly and efficiently change molds to adapt to different production needs. In this process, foaming molding is a key step, and the mold changing device, as a core component of the foaming equipment, directly determines production efficiency and product quality.

[0003] Chinese Patent CN117102456A discloses a quick mold changing device for die-casting molds of new energy vehicle parts. The device includes a base plate, a mounting plate connected to the top of the base plate, a lifting assembly above the mounting plate, a material transfer assembly connected to the movable end of the lifting assembly, and a clamping assembly above the material transfer assembly. This device uses the lifting assembly to automatically control the lifting plate to move upwards, thereby lifting the material transfer assembly and clamping assembly above the lifting plate to below the mold, avoiding shaking during hoisting and ensuring greater stability of the mold during unloading and installation.

[0004] Generally, EPP foam product molds are divided into upper molds and lower molds. The lower mold is usually fixed to the worktable, while the upper mold is installed on the lifting end of the lifting device. In the current equipment, the two clamping components are located at the top of the fixed box. When the lifting component drives the fixed box to lower the clamping components, the worktable will obstruct the movement path of the clamping components, making it difficult for them to move to the top of the worktable (i.e., the location of the lower mold). Therefore, the clamping components cannot reach and clamp the lower mold, ultimately resulting in the inability to complete the mold changing operation. Utility Model Content

[0005] To address the problem that existing mold-changing devices are not easy to change molds on the worktable, this utility model proposes a mold-changing device for EPP foam materials to overcome the aforementioned technical problems in existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a mold changing device for EPP foam material, including a movable base, a steering component on the top of the movable base, a lifting component on the top of the steering component, a support frame on the lifting end of the lifting component, the support frame on both sides of the lifting component, a clamping component inside the support frame, and a support component inside the clamping component.

[0008] The support frame is raised to a suitable height by the lifting assembly, and then the movable seat moves the support frame and clamping assembly to the upper side of the worktable by the lifting assembly, so that the clamping assembly clamps and fixes the mold.

[0009] Furthermore, the steering assembly includes an I-shaped disk, which is rotatably connected to a movable seat. A shielding box is fixedly installed at the bottom of the movable seat. A driven gear is provided inside the shielding box. The driven gear is fixedly connected to the I-shaped disk. A driving gear meshes with the outer surface of the driven gear. A steering motor is fixedly installed at the top of the movable seat. The output end of the steering motor is fixedly connected to the driving gear.

[0010] Furthermore, the lifting assembly includes a gantry frame, which is fixedly connected to the top of the I-beam. A lifting screw is rotatably connected inside the gantry frame, and a lifting plate is threadedly connected to the outer surface of the lifting screw. A guide rod is fixedly connected inside the gantry frame and is movably connected to the lifting plate. A support frame is fixedly connected to the lifting plate. A lifting motor is fixedly installed on the top of the gantry frame, and the output end of the lifting motor is fixedly connected to the lifting screw.

[0011] Furthermore, the clamping assembly includes a bidirectional screw, which is rotatably connected to the support frame. A clamping plate is threaded onto the outer surface of the bidirectional screw. Two clamping plates are symmetrically arranged. A support rod is fixedly connected to the back of the clamping plate. The support rod is movably connected to the support frame. A clamping motor is fixedly installed on the outer side of the support frame. The output end of the clamping motor is fixedly connected to the bidirectional screw.

[0012] Furthermore, the support assembly includes a rotating groove, which is formed at the bottom of the clamping plate. A rotating shaft is rotatably connected inside the rotating groove, and an L-shaped support plate is fixedly connected to the outer surface of the rotating shaft. A storage box is fixedly connected to one side of the clamping plate. A storage gear is rotatably connected inside the storage box, and a storage rack meshes with the outer side of the storage gear. The top and bottom ends of the storage rack extend to the outside of the storage box.

[0013] Furthermore, a T-shaped fixing rod is fixedly connected to one side of the storage box, and a connecting plate is movably connected to the outer surface of the T-shaped fixing rod. The connecting plate is fixedly connected to the storage rack, a return spring is fixedly connected to the top of the connecting plate, and a ball bearing is rotatably connected to the bottom end of the storage rack.

[0014] Furthermore, several casters are fixedly installed at the bottom of the movable seat.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model uses a lifting component to raise and lower the clamping component to a suitable height. Then, the lifting component, support frame, and clamping component are moved by a movable seat. Since there are no obstructions at the bottom of the support frame and clamping component, the support frame and clamping component can be moved normally to the upper side of the worktable, and the clamping component can clamp the mold normally. The above setting effectively solves the problem of space obstruction and ensures the smooth progress of mold changing operations.

[0017] 2. After the mold is clamped and fixed by the bidirectional screw and clamping plate, the support frame drives the clamping plate and the mold to move upward. As the distance between the bottom of the mold and the worktable increases, the return spring pushes the connecting plate to move downward, which in turn drives the rack to move downward synchronously. The downward movement of the rack drives the rack to rotate, and through the rotating shaft, the L-shaped support plate rotates to the bottom of the mold. The L-shaped support plate, which can automatically rotate to the bottom of the mold, significantly improves the stability and safety of mold transportation, effectively distributes the weight of the mold to reduce the load on the clamping mechanism, and prevents the mold from sinking or deforming during the lifting and moving process, thereby ensuring that the mold changing operation is smooth, safe and reliable.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0030] Please see Figures 1-6 As shown, this utility model is a mold changing device for EPP foam material, including a movable seat 1, a steering component 2 is provided on the top of the movable seat 1, a lifting component 3 is provided on the top of the steering component 2, a support frame 4 is provided at the lifting end of the lifting component 3, the support frame 4 is provided on both sides of the lifting component 3, a clamping component 5 is provided inside the support frame 4, and a support component 6 is provided inside the clamping component 5.

[0031] The support frame 4 is raised or lowered to a suitable height by the lifting component 3. Then, the movable seat 1 moves the support frame 4 and the clamping component 5 to the upper side of the worktable by the lifting component 3, so that the clamping component 5 clamps and fixes the mold.

[0032] The clamping component 5 on one side of the lifting component 3 clamps and fixes the mold to be installed. Then, the lifting component 3 moves the two clamping components 5 and the clamped mold to a suitable height through the support frame 4. At the same time, the moving seat 1 moves the clamping component 5 on the other side to the worktable, so that the clamping component 5 clamps the mold that has been disassembled on the worktable. Then, the lifting component 3 is rotated by the steering component 2, so that the mold to be installed can be rotated to the worktable, and then the mold is installed on the worktable.

[0033] The lifting assembly 3 raises and lowers the clamping assembly 5 to a suitable height. Then, the moving seat 1 moves the lifting assembly 3, the support frame 4, and the clamping assembly 5. Since there are no obstructions at the bottom of the support frame 4 and the clamping assembly 5, the support frame 4 and the clamping assembly 5 can move normally to the upper side of the worktable. At the same time, the clamping assembly 5 can clamp the mold normally. The above settings effectively solve the space obstruction problem and ensure the smooth progress of mold changing operations.

[0034] In one embodiment, the steering assembly 2 includes an I-shaped disk 201, which is rotatably connected to a movable seat 1. A shielding box 202 is fixedly installed at the bottom of the movable seat 1. A driven gear 203 is disposed inside the shielding box 202. The driven gear 203 is fixedly connected to the I-shaped disk 201. A driving gear 204 meshes with the outer surface of the driven gear 203. A steering motor 205 is fixedly installed at the top of the movable seat 1. The output end of the steering motor 205 is fixedly connected to the driving gear 204.

[0035] The steering motor 205 drives the drive gear 204 to rotate, and the rotating drive gear 204 drives the I-shaped disk 201 to rotate on the moving seat 1 through the driven gear 203. When the I-shaped disk 201 rotates 180°, the clamping components 5 on both sides of the lifting component 3 can be adjusted in position. This setting allows the mold to be installed and the mold to be disassembled to be adjusted in position, so that the device does not need to be moved frequently when disassembling and installing the mold.

[0036] In one embodiment, the lifting assembly 3 includes a gantry frame 301, which is fixedly connected to the top of the I-beam plate 201. A lifting screw 302 is rotatably connected inside the gantry frame 301, and a lifting plate 303 is threadedly connected to the outer surface of the lifting screw 302. A guide rod 304 is fixedly connected inside the gantry frame 301 and is movably connected to the lifting plate 303. A support frame 4 is fixedly connected to the lifting plate 303. A lifting motor 305 is fixedly installed on the top of the gantry frame 301, and the output end of the lifting motor 305 is fixedly connected to the lifting screw 302.

[0037] The lifting screw 302 is driven by the lifting motor 305. At this time, the lifting plate 303 can move inside the gantry frame 301 under the drive of the lifting screw 302 and the guidance of the guide rod 304. The moving lifting plate 303 can drive the two clamping components 5 to adjust their height through the support frame 4. This setting, through the lifting adjustment function, enables the clamping components 5 to adapt to worktables of different heights, thereby realizing reliable clamping of molds on worktables of various specifications.

[0038] In one embodiment, the clamping assembly 5 includes a bidirectional screw 501, which is rotatably connected to the support frame 4. A clamping plate 502 is threadedly connected to the outer surface of the bidirectional screw 501. Two clamping plates 502 are symmetrically arranged. A support rod 503 is fixedly connected to the back of the clamping plate 502. The support rod 503 is movably connected to the support frame 4. A clamping motor 504 is fixedly installed on the outer side of the support frame 4. The output end of the clamping motor 504 is fixedly connected to the bidirectional screw 501.

[0039] By moving the support frame 4 to the outside of the mold, and then driving the bidirectional screw 501 through the clamping motor 504, the two clamping plates 502 can move towards the mold simultaneously under the drive of the bidirectional screw 501 and the guidance of the support rod 503, and complete the clamping and fixing of it.

[0040] In one embodiment, the support component 6 includes a rotating groove 601, which is formed at the bottom of the clamping plate 502. A rotating shaft 602 is rotatably connected inside the rotating groove 601. An L-shaped support plate 603 is fixedly connected to the outer surface of the rotating shaft 602. A storage box 604 is fixedly connected to one side of the clamping plate 502. A storage gear 605 is rotatably connected inside the storage box 604. A storage rack 606 meshes with the outer side of the storage gear 605. The top and bottom ends of the storage rack 606 extend to the outside of the storage box 604.

[0041] After the two clamping plates 502 are moved to the upper side of the worktable by the movable seat 1, the support frame 4 is moved downward by the lifting screw 302. During this process, the storage rack 606 first comes into contact with the worktable. As the support frame 4 moves downward, the storage rack 606 can move inside the storage box 604. The moving storage rack 606 can drive the storage gear 605 to rotate. The rotating storage gear 605 then drives the L-shaped support plate 603 to rotate towards the back of the clamping plate 502 through the rotating shaft 602. The above arrangement allows the bottom of the clamping plates 502 to come into normal contact with the worktable, and also allows the two clamping plates 502 to properly clamp and fix the mold.

[0042] In one embodiment, for the storage box 604, a T-shaped fixing rod 607 is fixedly connected to one side of the storage box 604, a connecting plate 608 is movably connected to the outer surface of the T-shaped fixing rod 607, the connecting plate 608 is fixedly connected to the storage rack 606, a return spring 609 is fixedly connected to the top of the connecting plate 608, and a ball bearing 610 is rotatably connected to the bottom end of the storage rack 606.

[0043] The ball bearing 610 at the bottom of the rack 606 contacts the top of the worktable under the push of the return spring 609. When the clamping plate 502 contacts the top of the processing table and is driven by the bidirectional screw 501, the ball bearing 610 can roll on the worktable. This arrangement reduces the friction between the rack 606 and the processing table. After the mold is clamped and fixed, the support frame 4 moves the clamping plate 502 and the mold upward. As the distance between the clamping plate 502 / the bottom of the mold and the worktable gradually increases, the return spring 609 pushes the connecting plate 608 downward. Guided by the T-shaped fixing rod 607, the connecting plate 608 moves the rack 606 downward synchronously, thereby driving the rack 605 to rotate, and driving the L-shaped support plate 603 to rotate into place at the bottom of the mold through the rotating shaft 602. At this time, the mold is precisely guided by the clamping plates 502 on both sides, and its gravity acts vertically on the horizontal support surface of the L-shaped support plate 603. The torque generated by the gravitational load at the pivot 602 forms a static balance with the holding force of the transmission system (housing rack 606 / housing gear 605), effectively locking the rotational freedom of the L-shaped support plate 603. This design allows the clamping plate 502 (lateral constraint) and the L-shaped support plate 603 (bottom support) to work together, providing multiple layers of protection during mold transfer and significantly reducing the risk of mold detachment.

[0044] In one embodiment, for the aforementioned casters 7, a plurality of casters 7 are fixedly installed on the bottom of the movable seat 1.

[0045] The movable seat 1 can be driven by the casters 7, which allows the movable seat 1 to move the entire device. This design makes it convenient to adjust the position of the two support frames 4, and also makes it convenient to transfer the clamped mold.

[0046] Through the above technical solution, 1. The lifting component 3 raises and lowers the clamping component 5 to a suitable height, and then the moving seat 1 moves the lifting component 3, the support frame 4, and the clamping component 5. At this time, since there are no obstructions at the bottom of the support frame 4 and the clamping component 5, the support frame 4 and the clamping component 5 can move normally to the upper side of the worktable, and the clamping component 5 can normally clamp the mold. The above setting effectively solves the space obstruction problem and ensures the smooth progress of mold changing operations; 2. After the mold is clamped and fixed by the bidirectional screw 501 and the clamping plate 502, the support frame 4 drives the clamping plate 502. As the mold moves upward, the distance between the bottom of the mold and the worktable increases. The return spring 609 pushes the connecting plate 608 downward, which in turn drives the rack 606 to move downward synchronously. The downward movement of the rack 606 drives the rack 605 to rotate, and through the rotating shaft 602, the L-shaped support plate 603 rotates to directly below the mold. The L-shaped support plate 603, which can automatically rotate to the bottom of the mold, significantly improves the stability and safety of mold transfer, effectively distributes the weight of the mold to reduce the load on the clamping mechanism, and prevents the mold from sinking or deforming during the lifting and moving process, thereby ensuring that the mold changing operation is carried out smoothly, safely and reliably.
