Description

Technical Field

[0001] This utility model relates to the field of mold transfer equipment technology, and in particular to a collision-proof transfer equipment for ceramic molds. Background Technology

[0002] Ceramic molds are fundamental process equipment in the production of ceramic products, especially large-sized products such as sanitary ceramics. These molds are typically made of hard and brittle materials such as plaster, and are not only large and heavy, but their surface precision directly affects the quality of the final product. During production, molds need to be frequently moved between different processes such as molding, drying, and storage. Therefore, efficient and safe transfer is a key link in ensuring production continuity.

[0003] Currently, the transfer of ceramic molds in factories mostly relies on general-purpose equipment such as overhead cranes, forklifts, or ordinary flatbed trolleys. When using such equipment for transfer, the stability of the molds mainly depends on the experience and careful operation of the operators. However, during startup, braking, or turning, the inertia generated by the equipment can easily cause the molds to sway or shift position. In addition, the complex environment of the production workshop, with the possibility of other equipment or obstacles in the passageways, makes the risk of collisions between the molds and the outside world during movement relatively high.

[0004] Even a minor impact can cause cracks and chipping at the edges of molds made of brittle materials, and in severe cases, they may even shatter and become unusable. This not only results in economic losses for the mold itself but also disrupts production plans and affects the efficiency of the entire production line. Furthermore, repairing or replacing damaged molds requires additional time and labor costs, placing an unnecessary burden on the company.

[0005] In response to this technical problem, this application proposes a collision-resistant transfer device for ceramic molds. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-collision transfer device for ceramic molds. The device automatically and smoothly returns to its initial protective position, exhibits excellent overall buffering performance, reliable linkage, and durability, significantly improving protection and operational safety.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A collision-resistant transfer device for ceramic molds includes a placement platform and clamping plates symmetrically slidably disposed on the top of the placement platform. A knob is rotatably connected inside the clamping plate, and a threaded rod is fixedly connected to the bottom of the knob. A sliding plate, threadedly engaged with the threaded rod, is slidably disposed inside the clamping plate. Fixed rods are fixedly connected to both sides of the sliding plate. One end of the fixed rod, away from the sliding plate, passes through the side wall of the clamping plate and is rotatably connected to a limit block. A limit plate, meshing with the limit block, is fixedly disposed on the placement platform. A buffer plate is slidably connected to the side wall of the placement platform. A movable frame is slidably disposed within the cavity of the placement platform. The buffer plate and the movable frame are connected by a linkage mechanism.

[0009] Furthermore, a groove is provided on the limiting block, and the end of the fixing rod away from the sliding plate slides and rotates in the groove.

[0010] Furthermore, the limiting plate is a rack structure, and the end of the limiting block is formed into a tooth shape that meshes with the rack structure.

[0011] Furthermore, the linkage mechanism includes a main rotating rod, a secondary rotating rod, and at least two sliders; the sliders are slidably connected to the inner side of the buffer plate; one end of the main rotating rod is rotatably connected to the slider, and the other end is rotatably connected to the placement platform; one end of the secondary rotating rod is rotatably connected to the slider, and the other end is rotatably connected to the movable frame.

[0012] Furthermore, the inner wall of the placement platform is provided with a groove, and the end of the main rotating rod away from the slider is slidably connected to the groove by rotating the slider.

[0013] Furthermore, the end of the secondary rotating rod away from the slider is rotatably connected to the side wall of the movable frame.

[0014] Furthermore, a connecting block is fixedly connected to the middle of the movable frame, and the main rotating rod and the auxiliary rotating rod are connected to the movable frame through the connecting block.

[0015] Furthermore, the linkage mechanism is symmetrically arranged on both sides of the movable frame.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, the mold can be initially clamped by manually sliding the clamping plate. Then, rotating the knob on the inner wall of the clamping plate drives the internal mechanism to quickly lock the clamping plate position, eliminating the need for a complex clamping structure. The device is highly versatile and can be adapted to molds of different specifications through flexible adjustment, ensuring stable and secure clamping. It effectively avoids mold displacement and accidental damage during transportation, significantly improving protection and operational safety.

[0018] 2. In this invention, when the equipment is accidentally impacted on both sides during mold transfer, the built-in linkage buffer mechanism actively responds. The impact force pushes the buffer plate inward, and through a precisely linked rotating rod and slider mechanism, it efficiently drives the core moving frame to compress inward synchronously. The air inside the moving frame is rapidly pressurized, flexibly absorbing and dissipating the impact energy, significantly reducing the vibration transmitted to the mold. After the impact disappears, the structure automatically and smoothly returns to the initial protective position. The overall buffering performance is excellent, the linkage is reliable, and it is durable. Attached Figure Description

[0027] 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.

[0028] Reference Figure 1-3This utility model provides an embodiment of a collision-resistant transfer device for ceramic molds, comprising a placement platform 1 and a clamping plate 2 symmetrically slidably disposed on the top of the placement platform 1. A knob 3 is rotatably connected inside the clamping plate 2, and a threaded rod 4 is fixedly connected to the bottom of the knob 3. A sliding plate 5 is slidably disposed inside the clamping plate 2 and threadedly engaged with the threaded rod 4. Fixed rods 6 are fixedly connected to both sides of the sliding plate 5. The end of the fixed rod 6 away from the sliding plate 5 passes through the side wall of the clamping plate 2 and is rotatably connected to a limiting block 7. A limiting plate 9 that meshes with the limiting block 7 is fixedly disposed on the placement platform 1. A buffer plate 10 is slidably connected to the side wall of the placement platform 1. A movable frame 11 is slidably disposed in the inner cavity of the placement platform 1. The buffer plate 10 and the movable frame 11 are connected by a linkage mechanism. A groove 8 is provided on the limiting block 7. The end of the fixed rod 6 away from the sliding plate 5 slides and rotates in the groove 8. The limiting plate 9 is a rack structure, and the end of the limiting block 7 is formed into a tooth shape that meshes with the rack structure.

[0029] Specifically: In the delicate transfer operations of ceramic product manufacturing, the fragility of ceramic molds makes them prone to chipping, cracking, or surface scratches due to impacts, leading to product defects or even direct scrapping. This places stringent requirements on the fixing and protection performance of transfer equipment. The core innovation of this ceramic mold anti-collision transfer equipment lies in its efficient, stable, and highly adaptable clamping and positioning mechanism. At the beginning of the operation, the operator places the clean ceramic mold stably on the sturdy placement platform 1. Then, the operator manually pushes the two clamping plates 2 placed on the platform inward, so that they fit against the side wall of the mold and slide smoothly on the pre-set guide inner wall inside the placement platform 1, achieving preliminary but reliable synchronous clamping of both sides of the mold. At this time, the main body of the mold has been effectively constrained, but the potential risk of slight displacement under the dynamic load of subsequent transfer has not been eliminated.

[0030] To completely lock this critical clamping state, the operator then gently turns the knob 3 installed on the inner wall of any clamping plate 2. The action of this knob 3 directly drives the threaded rod 4 rigidly connected at its bottom to rotate precisely. Under the action of the thread, the sliding plate 5, which is precisely engaged with the threaded rod 4 on the outer wall, begins to move smoothly along the inner wall of the dedicated track inside the clamping plate 2. The movement of the sliding plate 5 simultaneously pulls the rigid fixing rods 6 fixed on both sides of its outer wall to make linear displacement.

[0031] These fixing rods 6 are cleverly embedded in the inner wall of the pre-set straight-through groove 8 on the edge of the placement platform 1. The forced outward movement of the fixing rods 6 within the groove 8 ultimately drives the two connected limiting blocks 7 to push forcefully outward. The key locking action is completed here: the limiting blocks 7 pushed out on both sides are precisely embedded into the corresponding locking grooves or recesses on the rigid limiting plates 9 that are fixed to or integrally formed with the main body of the placement platform 1. This embedding process produces a hard mechanical engagement or strong locking effect. At this moment, the position of the clamping plate 2 is instantly and forcibly locked in its current clamping position of the mold, absolutely eliminating any possibility of reverse loosening or displacement. Through the above concise and coherent manual operation flow, it mainly involves two actions: clamping and slight rotation—the mold in the transfer equipment This design achieves zero-movement degree-of-freedom locking, eliminating complex hydraulic, pneumatic, or multi-lever clamping systems and relying purely on the reliability of mechanical locking. With the drive of knob 3 and the fine and continuous adjustability of the sliding plate 5's movement distance, combined with the flexible positioning of the fixing rod 6 within the length range of the slide groove 8, the spacing when the limiting block 7 is embedded in the limiting plate 9 can be steplessly adapted to ceramic molds of different widths, exhibiting excellent versatility. The final clamping state is extremely rigid and has a very strong resistance to vibration and displacement. It provides an extremely effective static constraint and dynamic buffer isolation layer for brittle ceramic molds throughout the entire loading, unloading, lifting, translation, and transportation path, perfectly eliminating the risk of damage caused by mold slippage or accidental collision displacement, significantly improving product yield and extending the service life of expensive precision molds.

[0032] Reference Figures 4-6 The linkage mechanism includes a main rotating rod 14, a secondary rotating rod 15, and at least two sliders 13. The sliders 13 are slidably connected to the inner side of the buffer plate 10. One end of the main rotating rod 14 is rotatably connected to the slider 13, and the other end is rotatably connected to the placement platform 1. One end of the secondary rotating rod 15 is rotatably connected to the slider 13, and the other end is rotatably connected to the movable frame 11. The inner wall of the placement platform 1 has a groove 12. The end of the main rotating rod 14 away from the slider 13 is rotatably connected to the groove 12 by rotating the slider 13. The end of the secondary rotating rod 15 away from the slider 13 is rotatably connected to the side wall of the movable frame 11. A connecting block 16 is fixedly connected to the middle of the movable frame 11. The main rotating rod 14 and the secondary rotating rod 15 are connected to the movable frame 11 through the connecting block 16. The linkage mechanism is symmetrically arranged on both sides of the movable frame 11.

[0033] Specifically: Given the fragility of ceramic molds and the requirement for excellent dynamic protection during transport, the impact energy absorption and conversion system designed for this equipment is crucial. When an external force is accidentally applied to both sides of the equipment during transport, its core protection mechanism is immediately activated. When the impact force is transmitted to the equipment, it pushes the buffer plates 10 on both sides, which are rigidly or elastically connected to the outer structure of the equipment, to overcome the initial reset force and slide synchronously towards the inner center of the placement platform 1. This process constitutes the first line of defense for impact energy absorption. The inward displacement of the buffer plates 10 is not an isolated action. It efficiently drives the internal linkage mechanism through a precision force transmission structure. Its action first forces the main rotating rods 14 on both sides to deflect at a clear angle around their fixed axis. The rotational motion of the main rotating rods 14 is transmitted through a specific mechanism at their moving end. Specifically, the rotation of the main rotating rods 14 is precisely converted into a forced linear displacement of a slider 13 hinged to its moving end within the inner wall of the preset guide channel moving frame 11. This stage effectively converts the translational energy of the impact into the rotational and sliding kinetic energy within the mechanism and begins to dissipate energy.

[0034] More importantly, the sliding of a single slider 13 on the inner wall of the moving frame 11 will inevitably drive another slider 13, symmetrically arranged with it, to slide synchronously and in the opposite direction on the inner wall of its matching groove 12 through the connecting mechanism. The ingenuity of this symmetrical linkage design lies in the fact that it not only ensures the balance of forces on both sides and prevents the mold from tilting, but also forces the other slider 13 to directly or indirectly drive the connecting block 16 connected to it to make a definite positional change. The movement trajectory of the connecting block 16 is constrained, and it immediately causes the auxiliary rotating rod 15 rigidly connected to its other side to produce a synchronous rotation. The rotation of the auxiliary rotating rod 15 serves as the final execution link, powerfully transmitting the force to the core frame of the moving frame 11. This drives the entire moving frame 11 structure to overcome the resistance of the built-in damper and slide and compress stably and controllably towards the internal space defined by the placement platform 1 and the connecting block 16. At this time, the pre-encapsulated, specific-volume sealed air cavity inside the moving frame 11 begins to play its core buffering function: as the moving frame 11 continues to contract and move inward steadily under the joint compression of the placement platform 1 and the connecting block 16, the air inside is rapidly compressed, and its volume decreases, causing the pressure to rise sharply.

[0035] Air, as a highly compressible medium, can efficiently convert the incoming, potentially damaging impact kinetic energy into intramolecular energy and heat during rapid compression, achieving flexible energy dissipation and time extension, thus minimizing the peak value of transient impact force. This pneumatic buffering process exhibits significant nonlinear characteristics: it provides a large buffering force in the initial stage of impact, and the increase in buffering force slows down as the stroke progresses, providing a smooth deceleration curve, which is crucial for protecting fragile ceramic molds. When the externally applied impact energy is fully dissipated by the compressibility of air and inter-structural friction, the end of the buffering process is triggered: the potential energy accumulated in the compressed air, the energy stored in the elastic elements of the structure, or the driving force generated by the air pressure difference will effectively drive the entire linkage chain to move in the opposite direction. Specifically, the moving frame 11 is affected by internal air pressure / elastic potential. Under the influence of energy, it begins to slide outward and expand to reset. This action, through the linkage mechanism of the secondary rotating rod 15, connecting block 16, slider 13 and main rotating rod 14, ultimately drives the buffer plates 10 on both sides to smoothly return to their original preset standby positions, preparing for the next possible impact. The entire buffering and reset process is highly automated and requires no manual intervention, ensuring that the equipment can quickly return to a stable protective state after an impact. This precise mechanical transmission chain realizes multi-level energy conversion and has extremely strong linkage. At the same time, because its core buffering relies on air compression and mechanical elastic reset, the overall structure has high durability and excellent reliability, providing flexible protection for brittle ceramic molds under high-intensity impacts in a long-lasting and stable manner, greatly reducing the risk of collision damage. It is an important supplement to the function of locking and fixing structures to prevent accidental slippage, forming a comprehensive protection that combines rigidity and flexibility.

[0036] Working principle:

[0037] First, place the mold on the placement platform 1 and manually move the clamping plates 2 on both sides so that the clamping plates 2 slide on the inner wall of the placement platform 1 to clamp the mold on both sides. Then, rotate the knob 3 on the inner wall of the clamping plate 2. The knob 3 drives the threaded rod 4 fixed at the bottom to rotate. The threaded rod 4 drives the sliding plate 5 connected to the outer wall threadedly, so that the sliding plate 5 slides on the inner wall of the clamping plate 2. This drives the fixed rods 6 on both sides of the outer wall to move and slide on the inner wall of the slide groove 8, thereby driving the limit blocks 7 on both sides to slide outward. Insert the limit blocks 7 into the limit plate 9 to limit the clamping plate 2. This completes the fixation of the mold and quickly locks the position of the clamping plate 2. No complicated clamping structure is required. It can be adapted to different specifications of molds and the limit distance can be flexibly adjusted. It is stable and easy to operate. It effectively avoids mold displacement and damage from bumps during transportation and has strong protection.

[0038] The main body of the anti-collision transfer equipment is an electric motor vehicle. When the mold needs to be moved, the electric drive module at the bottom can be activated by an external controller to make the bottom wheels rotate, thereby driving the mold and the device to move. If there is an impact on both sides, the buffer plates 10 on both sides of the placement platform 1 will slide inward. When the buffer plates 10 move, they will drive the main rotating rods 14 on both sides to rotate and the sliders 13 to slide on the inner wall of the moving frame 11, and drive the sliders 13 on the other side to slide in the groove 12. At the same time, the auxiliary rotating rods 15 on the other side of the connecting block 16 will rotate, thereby driving the moving frame 11 to slide inward synchronously. This allows the air inside the placement platform 1 and the connecting block 16 to be squeezed and buffered. After the buffering is completed, the buffer plates 10 will return to their original positions, flexibly removing the impact force and reducing the damage from the collision. After the impact disappears, the structure will automatically reset, providing continuous and stable protection. The overall anti-collision buffering effect is good, the structure has strong linkage, and it is durable and reliable.
