Description

Technical Field

[0001] This invention relates to the field of mold transportation technology, and more specifically, to a molding mold transportation device. Background Technology

[0002] A mold is a tool used to create shaped objects. The material is molded in a mold to change its physical state in order to obtain the shape of the object we want.

[0003] Molds are precision tools with complex shapes, requiring high structural strength, rigidity, surface hardness, surface roughness, and machining accuracy. Therefore, special transport devices are needed to prevent damage during transportation. One existing mold transport device uses springs to bring the front end of a support plate close to the ground, placing the mold on it. However, when the mold's radial dimension is large, this device cannot transport multiple molds simultaneously, requiring multiple round trips, wasting manpower and resources. Furthermore, the lack of a mold-fixing device on the support plate during transport makes the mold prone to shaking and collisions, leading to wear and even damage, thus affecting its precision. Summary of the Invention

[0004] Therefore, in order to solve the problems of not being able to transport multiple molds simultaneously and the molds being prone to collisions during transportation, the present invention provides a molding mold transportation device, the specific technical solution of which is as follows:

[0030] In this invention, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0031] like Figures 1-3 As shown, a molding die 7 transport device according to an embodiment of the present invention includes a transport mechanism and a placement mechanism; the transport mechanism is used to transport a pallet 1, and the transport mechanism is arranged in sequence along the transport direction of the pallet 1, including a first feeding component 2, a transfer component 3 and a discharging component 4, and a plurality of positioning grooves 11 are provided in the pallet 1; the discharging component 4 includes a film covering structure 41 for covering the pallet 1; the placement mechanism includes a conveying frame 5 and an adsorption component 6 disposed on one side of the transfer component 3, the conveying frame 5 is used to transport the mold 7, and the adsorption component 6 includes a suction cup 641 for adsorbing the mold 7, and the mold 7 is adapted to the positioning groove 11.

[0032] The aforementioned mold 7 transport device, by providing a tray 1, with positioning grooves 11 on the tray 1 to limit and fix the mold 7, can keep the mold 7 stable and not easily shake during transport. In addition, the number of positioning grooves 11 can also realize the simultaneous transport of multiple molds 7, solving the problems of not being able to transport multiple molds 7 at the same time and the molds 7 being prone to collisions during transport. By providing a film covering structure 41, after the mold 7 is stored on the tray 1, a film can be covered on the surface of the tray 1 to achieve protection and safeguarding of the mold 7 during storage. By providing an adsorption component 6, the mold 7 can be transferred. After the finished mold 7 is discharged, it is first transported by the conveyor frame 5, and then transferred to the tray 1 for storage under the adsorption of the adsorption component 6.

[0033] like Figure 1 , Figure 2 and Figure 5 As shown, in one embodiment, the molding die 7 transport device further includes a worktable 8. The transport mechanism and the adsorption assembly 6 are both fixed on the worktable 8. A conveyor frame 5 is installed on one side of the worktable 8. A second feeding assembly 9 for a feeding cover plate 10 is provided on the worktable 8 near the unloading assembly 4. The cover plate 10 is fitted into the surface of the tray 1 and used to cover the tray 1. By providing the cover plate 10, the cover plate 10 protects the mold 7 inside the tray 1 and also prevents debris from entering the tray 1, ensuring that the mold 7 has good moisture-proof, sun-proof, waterproof, sealing, and heat-insulating functions when stored in the tray 1, adapting to various different storage environments.

[0034] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in one embodiment, the first feeding assembly 2 includes a first feeding frame 21 and a transverse structure 22. The first feeding frame 21 is provided with a first conveyor belt. The transverse structure 22 is used to transfer the pallet 1 from the first conveyor belt to the transfer assembly 3. The transverse structure 22 includes a transverse frame 221, a sliding member 222 and a clamping member 223. One end of the sliding member 222 is slidably mounted on the transverse frame 221, and the other end of the sliding member 222 is slidably connected to the clamping member 223. Clamping cylinders 2231 for abutting the pallet 1 are provided on both sides of the clamping member 223. Thus, by providing a first conveyor belt, the pallet 1 can be transported and loaded continuously and efficiently; by providing a sliding member 222, the sliding of the sliding member 222 on the transverse frame 221 can drive the clamping member 223 to move laterally, thereby enabling the clamping member 223 to clamp the pallet 1 and transfer it to the limiting channel 31; by providing a clamping cylinder 2231, the clamping cylinders 2231 on both sides can adjust the clamping gap between them respectively, thereby adapting to pallets 1 of different sizes.

[0035] like Figures 1-3As shown, in one embodiment, the transfer component 3 includes a limiting channel 31, a limiting cylinder 32, a clamping fixture 33, and a transfer frame 34 fixed on the worktable 8. The limiting channel 31 is located on the top of the transfer frame 34 and is used for placing the pallet 1. The limiting channel 31 has a loading position, a placement position, and a unloading position arranged sequentially along the moving direction of the pallet 1. The limiting cylinder 32 is fixedly connected to the placement position, and the output end of the limiting cylinder 32 is connected to the clamping fixture 33. The clamping fixture 33 is provided with a clamping part for engaging the corner of the pallet 1. By setting the limiting channel 31, the pallet 1 is easily positioned, ensuring the stability of the pallet 1 placed on the transfer frame 34. By setting the limiting cylinder 32, the limiting cylinder 32 controls the clamping fixture 33 to reciprocate towards the corner of the pallet 1, thereby positioning the pallet 1 and preventing the pallet 1 from shifting or even falling off during the placement of the mold 7, thus improving the efficiency of loading and unloading the mold 7.

[0036] like Figure 3 As shown, in one embodiment, the transfer component 3 further includes a moving structure 35, which includes a moving cylinder 351, a lifting plate 352, and a guide rail 353 mounted within the transfer frame 34. The moving cylinder 351 is slidably mounted on the guide rail 353, and its output end is connected to the lifting plate 352. A slot is provided in the limiting channel 31 for the lifting plate 352 to reciprocate through, and the top of the lifting plate 352 is used to abut against the bottom of the pallet 1. By providing the moving cylinder 351, the movement of the moving cylinder 351 on the guide rail 353 drives the movement of the lifting plate 352, thereby using the lifting plate 352 to adjust the position of the pallet 1 on the limiting channel 31, thus realizing the conveying of the pallet 1. At the same time, the moving cylinder 351 controls the lifting plate 352 to perform lifting and lowering movements, so that the lifting plate 352 can reciprocate against the bottom of the pallet 1, controlling the lifting and lowering movements of the pallet 1, thereby adjusting the height position of the pallet 1 and improving the accuracy and stability of the mold 7 during placement.

[0037] Specifically, the guide rail 353 is set in a horizontal direction.

[0038] like Figure 1 and Figure 5 As shown, in one embodiment, the unloading assembly 4 further includes an unloading rack 42 and a transverse structure 22. The unloading rack 42 is equipped with a second conveyor belt, and the transverse structure 22 is used to transfer the pallet 1 from the limiting channel 31 to the second conveyor belt. By providing the second conveyor belt, the pallet 1 after the mold 7 is stored can be transported continuously and efficiently.

[0039] like Figure 7As shown, in one embodiment, the coating structure 41 includes a shifting bracket 411, a first suction member 412, a guide plate 413, a gripper 414, a coating frame 415, and a film rolling roller 416. The shifting bracket 411 and the coating frame 415 are respectively installed at intervals on the worktable 8. The first suction member 412 and the gripper 414 are respectively slidably mounted on the shifting bracket 411. The guide plate 413 is fixed on the coating frame 415. The first suction member 412 is located above the guide plate 413 and is used to transfer the tray 1 from the second conveyor belt to the coating plate. The film rolling roller 416 is rotatably mounted on the coating frame 415. A protective film is wound on the film rolling roller 416. The gripper 414 is used to unwind the protective film from the film rolling roller 416 and coat it onto the tray 1 of the guide plate 413. Thus, by providing the first suction member 412, the sliding of the first suction member 412 on the shifting bracket 411 allows it to move synchronously with the gripper 414, thereby achieving the pressing and adhesion of the protective film on the tray 1 when the protective film is applied to the tray 1, completing the film application on the surface of the mold 7 inside the tray 1; by providing the gripper 414, the movement of the gripper 414 can unwind the protective film wound on the film roll 416, which is beneficial for applying the unwound protective film to the tray 1; by providing the guide plate 413, when the protective film is unwound, the guide plate 413 can provide a certain support position for the protective film, keeping it taut, which is convenient for subsequent film application operations.

[0040] Specifically, the first suction member 412 is provided with a suction head that can move up and down relative to the film plate.

[0041] like Figure 1 , Figure 2 and Figure 5 As shown, in one embodiment, the conveyor frame 5 is provided with multiple fitting seats 51 at intervals to fit into the mold 7; the adsorption assembly 6 includes a base 61, a connecting arm 62, a connector 63, and an adsorption element 64. The base 61 is located on one side of the placement position. One end of the connecting arm 62 is rotatably connected to the top of the base 61, and the other end of the connecting arm 62 is rotatably connected to the connector 63. The adsorption element 64 is inserted into the connector 63, and a suction cup 641 is installed at the bottom of the adsorption element 64. In this way, by providing the fitting seats 51, the stability of the mold 7 during the conveying and feeding process is ensured, and its fall off is prevented; by providing the connecting arm 62 and the connector 63, the rotation of the two can drive the adsorption element 64 to adjust its adsorption position, thereby improving the adsorption accuracy of the mold 7.

[0042] like Figure 3 and Figure 4As shown, in one embodiment, the suction cup 641 includes a suction head 6411 and a connecting seat 6412 installed at the bottom of the suction member 64. The connecting seat 6412 has a groove, and the suction head 6411 is set on the port of the groove and protrudes outward from the groove through the connecting member. A pulling structure for twisting the suction head 6411 is also provided between the suction head 6411 and the connecting seat 6412.

[0043] like Figure 4 As shown, the connector further includes a protrusion 6413 and a screw 6414. The protrusion 6413 is disposed at the bottom of the groove, and the screw 6414 is fixedly connected to the center of the suction head 6411. A screw hole is provided in the protrusion 6413, and the screw 6414 is threaded into the screw hole.

[0044] like Figure 4 As shown, the pulling structure further includes a pull rod 6415 and a screw 6416; the pull rod 6415 is inverted "L" shape, and its lower end is connected to the eccentric position of the suction head 6411. The upper plate portion is connected to the connecting seat 6412 through the fit between the screw 6416 and the screw 6416 hole on the bottom surface of the groove.

[0045] When the suction cup 641 is in use, the connecting seat 6412 moves downward under the gravity of the mold 7, and the force is transmitted to the suction head 6411 through the connecting piece. The suction head 6411 deforms under the force, and its middle part moves downward. The gas in the spherical crown is discharged from the periphery, and a closed negative pressure cavity is formed between the suction head 6411 and the mold 7. The pressure difference inside and outside the suction head 6411 is used to firmly adsorb the entire suction cup 641 onto the mold 7.

[0046] In addition, when it is necessary to adjust the adsorption position of the mold 7, the circumferentially twisted connecting seat 6412 and the pull rod 6415 twist the suction head 6411, causing the suction head 6411 to deform, breaking the seal between the suction cup 641 and the mold 7, allowing air to enter the suction head 6411, releasing the suction head 6411 from the mold 7, and the entire suction cup 641 can move freely under the action of external force.

[0047] like Figure 1 , Figure 2 , Figure 5 and Figure 8As shown, in one embodiment, the second feeding assembly 9 includes a second feeding rack 91, a second suction member 92, a lifting bracket 93, a lifting cylinder 94, and an upper cover plate 95 for placing the cover plate 10. The second feeding rack 91 and the lifting bracket 93 are respectively installed at intervals on the workbench 8. The second suction member 92 is slidably mounted on the second feeding rack 91. The lifting cylinder 94 is installed at the bottom of the lifting bracket 93. The output end of the lifting cylinder 94 extends to the top of the lifting bracket 93 and is connected to the upper cover plate 95 in a transmission manner. The second suction member 92 is used to transfer the cover plate 10 on the upper cover plate 95 to the tray 1 at the unloading position. Thus, by providing a second suction member 92, the sliding of the second suction member 92 on the second feeding rack 91 enables it to transfer the cover plate 10 to the top of the tray 1 and complete the sealing of the tray 1; by providing a lifting cylinder 94, the lifting cylinder 94 drives the lifting movement of the upper cover plate 95, thereby enabling the cover plate 10 on the upper cover plate 95 to be repeatedly raised, which facilitates the second suction member 92 to adsorb and clamp the cover plate 10.

[0048] Specifically, the second suction member 92 is also provided with a suction head that can move up and down relative to the film plate.

[0049] Working principle:

[0050] First, pallet 1 is fed from the first conveyor belt. When pallet 1 is fed to the discharge end of the first conveyor belt, the transverse structure 22 in the feeding assembly can transfer pallet 1 to the limiting channel 31 for placement and installation. Then, pallet 1 completes the position movement on the limiting channel 31 under the drive of the moving structure 35. When it moves to the placement position, the limiting cylinder 32 controls the clamping fixture 33 to clamp and fix the position of pallet 1.

[0051] At the same time, the mold 7 is fed and conveyed from the conveyor frame 5. During the conveying process of the mold 7, the adsorption component 6 transfers the mold 7 from the conveyor frame 5 to the tray 1 fixed at the placement position, thus completing the storage of the mold 7.

[0052] After the mold 7 is stored, the pallet 1 continues to move on the limiting channel 31 under the drive of the moving structure 35, and finally moves to the unloading position. Then the film coating structure 41 is activated. The protective film is unwound from the film roll 416 and extended to the top of the pallet 1 under the traction of the gripper 414. Under the drive of the first suction member 412, it is pressed and adhered to the upper surface of the pallet 1. After pressing, the protective film is cut by the operator manually or with the help of other automated equipment to complete the film coating operation.

[0053] After the film is applied to the surface of the tray 1, the second suction member 92 picks up the cover plate 10 and transfers it onto the tray 1 to cover it, thus completing the sealing and encapsulation. Then, the transverse moving structure 22 in the unloading assembly 4 is used to transfer the tray 1 onto the second conveyor belt for unloading.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
