Description

Technical Field

[0001] This utility model relates to the technical field of mold transfer equipment, and more specifically to an anti-slip mold transfer equipment. Background Technology

[0002] In the manufacturing and maintenance of automotive molds, flatbed transfer carts (also known as mold moving trolleys or mold transport carts) are key equipment for the safe and efficient transport of heavy molds. Flatbed transfer carts typically have a load capacity of 5-50 tons, and their design allows them to accommodate different mold sizes, such as small injection molds or large stamping dies. Furthermore, the flatbed transfer carts are powered by lithium batteries, making them particularly suitable for short-distance mold transfers in workshops without a power supply. Operators can control the cart directly using a remote control, making operation simple and convenient.

[0003] However, flatbed transport vehicles have a common problem: because there is no structure on the top of the vehicle to assist in supporting the car molds, the car molds on top are prone to slipping when the transport vehicle moves on slopes. Although there are transport flatbeds with cargo clamping structures on the top, as shown in prior art publication CN212861452U, the presence of these cargo clamping structures on the top of the transport vehicle occupies a certain amount of space, thus reducing the volume of items that can be transported. Moreover, the presence of these cargo clamping structures also increases the difficulty of transporting car molds: when moving the car molds to the top of the transport vehicle, the operator must manually control the lifted car molds to avoid the structure, which causes inconvenience to the car mold transport operation. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides an anti-slip mold transfer device. By using column boxes to limit the automotive mold placed on the top of the flatbed transfer vehicle from the top, it prevents the mold from slipping during the transfer process. After use, the limiting columns and support rods can be rotated and stored on the four sides of the flatbed transfer vehicle without occupying the space on the top of the flatbed transfer vehicle, ensuring that the top of the flatbed transfer vehicle is unobstructed and avoiding increasing the difficulty of lifting the automotive mold, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an anti-slip mold transfer device, comprising a flatbed transfer vehicle, wherein an automobile mold is placed on the top of the flatbed transfer vehicle, and limiting posts are provided on both sides of the flatbed transfer vehicle, and support rod groups are rotatably connected to both ends of the limiting posts, and multiple support rod groups are respectively provided on the front and rear sides of the flatbed transfer vehicle, wherein a movable seat for rotating the limiting posts to the top or side of the automobile mold is rotatably connected to the end of the support rod group away from the limiting posts;

[0006] The support rod assembly includes a support rod box, which contains a lifting assembly for driving the column box to move linearly along the support rod box, and for driving the limiting column to contact the automobile mold to restrict the movement of the automobile mold.

[0007] In a preferred embodiment, the lifting assembly includes a threaded rod threadedly connected inside the support rod box, and a movable plate is threadedly connected to the outer end of the threaded rod. There are two threaded rods located inside each support rod box, and the two threaded rods are driven by a gear set. The rotating threaded rod drives the limiting column to move linearly between the two support rod boxes.

[0008] A hydraulic cylinder b is fixedly connected to one side of the movable plate by bolts. The hydraulic cylinder b is located between two threaded rods. After the piston rod end of the hydraulic cylinder b extends, it pushes the limiting post to move out from between the two support rod boxes to further expand the stroke of the limiting post.

[0009] In a preferred embodiment, the piston rod end of the hydraulic cylinder b is fixedly connected to a connecting box by bolts, and a rotating shaft is movably connected to the side of the connecting box near the limiting post by a bearing. A motor for driving the rotating shaft to rotate is installed at one end of the rotating shaft.

[0010] In a preferred embodiment, the limiting post includes a post box, the two ends of which are fixed to two rotating shafts located at the front and rear of the flatbed transport vehicle, respectively. Two hydraulic cylinders a arranged side by side are fixed inside the post box. The piston rod ends of the two hydraulic cylinders a are fixedly connected to the hydraulic cylinders a by bolts. After the piston rod ends of the hydraulic cylinders a extend out, they push the pressure rod to move linearly.

[0011] In a preferred embodiment, the end of the pressure bar away from the flatbed transfer vehicle is processed into an arc shape and assembled from a sponge and an arc-shaped leather sleeve. The sponge is filled inside the leather sleeve. The part of the pressure bar connected to the hydraulic cylinder a is made of a plastic plate. When in use, the arc-shaped end can be rotated toward the car mold and come into contact with the car mold to avoid hard objects squeezing the car mold and causing damage to the car mold.

[0012] In a preferred embodiment, the support rod box has openings on the side near the flatbed transfer vehicle and at the end near the limiting post for the connection box to move.

[0013] In a preferred embodiment, the movable seat includes a movable box and a guide rail. The movable box is bolted to a plurality of linear motors on the side near the flatbed transport vehicle. The guide rail is bolted to the front and rear sides of the flatbed transport vehicle. The linear motors drive the movable box to move along the guide rail.

[0014] In a preferred embodiment, a rotating joint is fixed at one end of the support rod box near the movable box, the rotating joint being rotatably connected inside the movable box, and a reduction motor for driving the rotating joint to rotate is provided on the side of the movable box away from the flatbed transport vehicle.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. By using the support rod assembly to drive the column box to limit the car mold placed on the top of the flatbed transfer cart from the top, it can prevent the mold from slipping during the transfer process. After use, the limiting column and support rod assembly can be rotated and stored on the four sides of the flatbed transfer cart without occupying the space on the top of the flatbed transfer cart. This ensures that the top of the flatbed transfer cart is unobstructed and avoids increasing the difficulty of lifting the car mold. It achieves three benefits in one go.

[0017] 2. By rotating the support rod assembly into an inclined state, it is possible to limit the movement of the car mold from both sides, providing different limiting methods for operators to choose flexibly. At the same time, the hydraulic cylinder b and the threaded rod drive the column box to move between the two support rod assemblies, maximizing the stroke of the column box and enabling it to intercept taller and longer car molds, thereby expanding the scope of application of this utility model.

[0018] 3. The threaded rod can also be used to move the column box between the two support rod boxes, so that it can also be used to limit the movement of small-volume automotive molds, further enhancing the universality of this utility model. Attached Figure Description

[0029] 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.

[0030] Refer to the instruction manual appendix Figure 1-6 This utility model provides an anti-slip mold transfer device, including a flatbed transfer cart 1. When the mold needs to be transferred, the car mold can be placed directly on the top of the flatbed transfer cart 1. The flatbed transfer cart 1 is a handling device that does not require rails and is powered by batteries or cables. It is widely used in the fields of automotive molds, heavy machinery, warehousing and logistics. It is suitable for flexibly transferring heavy workpieces in the workshop. Commonly used models include DCB-50T and WCD-10T.

[0031] To limit the movement of the car mold when it is transported by the flatbed transfer cart 1 and to prevent the mold from slipping when the cart 1 is going up or down slopes, limit posts 2 are also installed on both sides of the flatbed transfer cart 1. Specifically, as shown in... Figure 2-6 As shown, the structure of the limiting post 2 includes a post box 21. Two hydraulic cylinders a22 arranged side by side are fixed inside the post box 21. The piston rod ends of the two hydraulic cylinders a22 are fixedly connected to the hydraulic cylinders a22 by bolts. After the piston rod ends of the hydraulic cylinders a22 extend out, they push the pressure rod 23 to move linearly. Moreover, the end of the pressure rod 23 away from the flatbed transfer vehicle 1 is processed into an arc shape. The pressure rod 23 consists of two parts. One part consists of a sponge and an arc-shaped leather sleeve. The sponge is filled inside the arc-shaped leather sleeve. The other part of the pressure rod 23 is the part connected to the hydraulic cylinder a22. This part of the pressure rod 23 is made of plastic plate. When in use, the arc-shaped end can be rotated to face the car mold and contact the car mold to avoid hard objects squeezing the car mold and causing damage to the car mold.

[0032] In order to drive the column box 21 to move as shown Figure 4-6The distance between the limiting post 2 and the flatbed transfer cart 1 needs to be adjusted according to the height and length of the car mold placed on top of the flatbed transfer cart 1, as shown in the figure. Figure 1 As shown, support rod assemblies 3 are rotatably connected to both ends of the limiting post 2, such as... Figure 2-6 As shown, this utility model has a total of four support rod groups 3, arranged in pairs. Each pair of support rod groups 3 is connected to one of two limiting posts 2. Specifically, as shown... Figure 2-6 As shown, each support rod group 3 includes a support rod box 31, and a column box 21 is installed between two support rod boxes 31. The support rod box 31 is provided with a lifting assembly for driving the column box 21 to move linearly along the support rod box 31. The lifting assembly includes a threaded rod 33 threadedly connected inside the support rod box 31. The outer end of the threaded rod 33 is threadedly connected to a moving plate 32. There are two threaded rods 33 inside each support rod box 31. The two threaded rods 33 are driven by a gear set 34. The rotating threaded rod 33 can drive the moving plate 32 to move up and down on the inner wall of the support rod box 31.

[0033] Furthermore, a hydraulic cylinder b35 is bolted to one side of the movable plate 32, and the hydraulic cylinder b35 is located between two threaded rods 33. The piston rod end of the hydraulic cylinder b35 is bolted to a connecting box 36. The support rod box 31 has openings for the connecting box 36 to move on both the side near the flatbed transfer vehicle 1 and the end where the column box 21 is installed. A rotating shaft 38 is movably connected to the side of the connecting box 36 near the limiting post 2 via a bearing. A motor 37 for driving the rotating shaft 38 is installed at one end of the rotating shaft 38. The motor 37 is installed inside the connecting box 36. Both ends of the column box 21 are fixed to two rotating shafts 38 located at the front and rear of the flatbed transfer vehicle 1, respectively. The rotating threaded rods 33 can drive the movable plate 32, the hydraulic cylinder b35, and the connecting box 36 and the column box 21 connected to the connecting box 36 to move up and down between the two support rod boxes 31. Figure 5 As shown, when column box 21 moves to... Figure 5 When the height is moderate, it can be used to limit some low-height, small-volume automobile molds;

[0034] If the height of the car mold on the top of the flatbed transfer vehicle 1 is less than the minimum height that the column box 21 can move between the two support rod boxes 31, the hydraulic cylinder a22 can be activated to drive the column box 21 to continue to move down, so that the column box 21 can contact the smaller car mold and limit it.

[0035] After the piston rod end of the hydraulic cylinder b35 is extended, it can push the column box 21 out from between the two support rod boxes 31, so that the movement path of the column box 21 is not limited to the two support rod boxes 31. This setting can move the column box 21 and the pressure rod 23 to the top of the car mold above the support rod boxes 31, so that the pressure rod 23 can limit the higher car mold from above, thus expanding the scope of application of this utility model.

[0036] It is worth noting that, in order to provide a longer travel distance for the column box 21 within a limited space, the hydraulic cylinders b35 and a22 used in this embodiment are both multi-stage hydraulic cylinders, and their travel distance is greater than their installation length. Telescopic cylinders such as the DSTH series can be used, and no further restrictions are imposed here.

[0037] Then, motor 37 needs to be started, and motor 37 drives the arc-shaped side of pressure rod 23 toward the car mold;

[0038] Next, rotate the limiting post 2 and the support rod assembly 3 to rotate the column box 21 to the top or side of the automotive mold, such as... Figure 1 As shown, a movable seat 4 is rotatably connected to the end of the support rod assembly 3 away from the limiting post 2;

[0039] Specifically, such as Figure 3-6 As shown: The movable seat 4 includes a movable box 41 and a guide rail 43. Multiple linear motors 42 are bolted to the side of the movable box 41 near the flatbed transfer vehicle 1. The guide rail 43 is bolted to the front and rear sides of the flatbed transfer vehicle 1. The linear motors 42 drive the movable box 41 to move along the guide rail 43. A rotating joint 39 is fixed to one end of the support rod box 31 near the movable box 41. The rotating joint 39 is rotatably connected inside the movable box 41. A reduction motor 44 is provided on the side of the movable box 41 away from the flatbed transfer vehicle 1 to drive the rotating joint 39 to rotate. In use, by starting the reduction motor 44, the support rod box 31 can be driven to rotate, and then the support rod box 31 drives the connecting box 36 and the column box 21 installed between the two connecting boxes 36 to rotate until the column box 21 is rotated to the top or side of the car mold.

[0040] If the car mold is placed on top of the flatbed transfer cart 1 near both ends, the linear motor 42 can be activated to drive the moving box 41 to move horizontally along the guide rail 43. Figure 6 As shown, until the column box 21 is moved above the car mold.

[0041] Next, the threaded rod 33 can be driven to rotate in the opposite direction, and the hydraulic cylinder b35 can be driven to shorten, causing the column box 21 to move towards the automobile mold until the column box 21 is in tight contact with the automobile mold. If the column box 21 is located in Figure 5 and Figure 6 The location shown allows for compression and fixation of the car mold from above, preventing slippage when the car mold travels over sloping surfaces such as door sills and ramps; if the pillar box 21 is located... Figure 6 The positions shown allow for limiting the car mold from both ends in the forward direction of the flatbed transfer vehicle 1. Because the ends of the car mold are limited by the column box 21, slippage of the car mold is prevented. This invention provides two different limiting methods for on-site operators to choose from flexibly.

[0042] It is worth noting that the motor 37 and geared motor 44 used in this embodiment can be NMRV series geared motors, and the drive device for driving the threaded rod 33 to rotate in both directions can be a Siemens 1LE1 series or ABB M2BA series three-phase asynchronous motor. This motor can support frequent driving of the threaded rod 33 to rotate in both directions, thereby achieving the purpose of driving the column box 21 to move up and down.

[0043] When not in use, the lever 23 can be rotated to the position shown. Figure 1 and Figure 2 As shown in the diagram, the curved side of the pressure rod 23 faces outwards from the flatbed transport vehicle 1. Utilizing the elasticity of the sponge material used in this part, it can cushion collisions between the two ends of the flatbed transport vehicle 1, providing additional protection for the vehicle during its movement. Furthermore, since both the flatbed transport vehicle 1 and the limiting post 2 are located on the outside of the flatbed transport vehicle 1, they do not occupy the space on top of the vehicle 1, thus not affecting the volume of the car mold that can be transported on top of the vehicle 1. In addition, the unobstructed design on the top of the flatbed transport vehicle 1 does not increase the difficulty of hoisting the car mold onto its top, achieving three benefits in one go.

[0044] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
