Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner radiator moulds, in particular to a movable feeding rod anti-deformation structure. Background Art

[0002] The feeding sub-mold is an indispensable part of the air conditioner radiator mold. At present, the movable feeding rod is generally made of aluminum to reduce weight. It is usually more than 1 meter long. The movable feeding rod is equipped with a feeding finger, which probes into the hole of the formed material strip through the feeding finger, thereby hooking the material strip and feeding it forward.

[0003] During use, the movable feeding rod is always moving and constantly collides with the limit blocks on the left and right sides. It is easy to bend and deform over time. The depth of the feeding finger into the material belt hole is about 1.5 mm. Once the deformation of the movable feeding rod is too large, the maximum deformation exceeds 0.5 mm, the feeding finger will not be able to hook the material belt hole, resulting in failure to feed normally, so the structure needs to be optimized. Utility Model Content

[0004] Based on the above problems, the purpose of the utility model is to provide a movable feeding rod anti-deformation structure, which can effectively control the deformation of the movable feeding rod and ensure the feeding accuracy.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A movable feeding rod anti-deformation structure comprises a lower template, on which a movable feeding rod and a limit block for limiting the travel of the movable feeding rod are arranged, wherein a wear-resistant pad is arranged on the surface of the lower template, the wear-resistant pad is located below the movable feeding rod, and a deformation-allowing gap is left between the wear-resistant pad and the bottom of the movable feeding rod.

[0007] As an optional scheme, the limit block is located on the side of the movable feeding rod, guide rods are provided at both ends of the movable feeding rod, and guide sleeve seats are provided on the lower template to cooperate with the guide rods at both ends. The guide sleeve seats support the two ends of the movable feeding rod and enable the movable feeding rod to translate along the axial direction of the guide rod. The middle part of the movable feeding rod is suspended relative to the lower template, and the wear-resistant pad is arranged along the moving path of the middle part of the movable feeding rod.

[0008] As an optional solution, the size of the allowable deformation gap is 0.05 mm.

[0009] As an optional solution, the wear-resistant pad and the limit block are respectively made of nylon.

[0010] As an optional solution, the wear-resistant pad is detachably connected to the lower template by countersunk screws.

[0012] In summary, compared with the prior art, the anti-deformation structure of the movable feeding rod prevents the movable feeding rod from undergoing further deformation by adding a wear-resistant pad to contact the bottom surface of the deformed movable feeding rod, thereby ensuring normal feeding of the feeding fingers. It has a simple structure, is easy to process and assemble, is quick to adjust, has low investment cost, and extends the service life of the mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1 and Figure 2 As shown, in order to solve the problem that the movable feeding rod 2 in the existing feeding sub-mold is prone to excessive bending and deformation and thus affects feeding, this preferred embodiment provides a movable feeding rod anti-deformation structure, including a lower mold plate 1, on which the movable feeding rod 2 and a limit block 3 for limiting the travel of the movable feeding rod 2 are arranged.

[0019] The surface of the lower template 1 is provided with a wear-resistant pad 4, which is located below the movable feed rod 2, and a deformation-allowing gap is left between the wear-resistant pad 4 and the bottom of the movable feed rod 2. The deformation-allowing gap is the allowable bending deformation of the movable feed rod 2. If the bending deformation continues, the movable feed rod 2 contacts the wear-resistant pad 4, and it is difficult to expand the deformation. In this embodiment, the size of the deformation-allowing gap is 0.05 mm.

[0020] It should be noted that, although friction will be generated when the movable feeding rod 2 contacts the wear-resistant pad 4, this friction is negligible compared to the feeding pulling force and will not affect the normal feeding, thereby ensuring the feeding accuracy.

[0021] Preferably, the wear-resistant pad 4 and the limit block 3 here are respectively made of nylon material with high wear resistance, and the wear-resistant pad 4 is detachably connected to the lower template 1 through the countersunk screw 5, which is convenient for replacing the wear-resistant pad 4 of different thickness and material, thereby reducing the overall maintenance cost of the mold.

[0022] Specifically, the limit block 3 is located on the side of the movable feeding rod 2, guide rods 6 are provided at both ends of the movable feeding rod 2, and the lower template 1 is provided with guide sleeve seats 7 that cooperate with the guide rods 6 at both ends to guide. The guide sleeve seats 7 support the two ends of the movable feeding rod 2 and enable the movable feeding rod 2 to translate along the axial direction of the guide rod 6. The middle part of the movable feeding rod 2 is suspended relative to the lower template 1, and the wear-resistant pad 4 is arranged along the moving path of the middle part of the movable feeding rod 2, that is, the wear-resistant pad 4 only needs to be arranged at the lowest point of the bending deformation of the movable feeding rod 2, which is convenient for mold modification.

[0023] In addition, a cover plate 8 is provided on the upper surface of the movable feeding rod 2, and a through hole is opened on the cover plate 8, in which a bushing 9 is installed, and a feeding finger 10 is installed in the bushing 9, and a spring 11 is provided between the feeding finger 10 and the movable feeding rod 2, so that the feeding finger 10 floats up and down in the through hole. Here, the normal depth of the feeding finger 10 probing into the material belt hole is about 1.5mm. After the wear-resistant pad 4 limits the movable feeding rod 2, it can ensure that the feeding finger 10 has a sufficient height to probe into the material belt hole, ensuring normal feeding.

[0024] During assembly, fasten the wear-resistant pad 4 to the lower mold plate 1, install the movable feed rod 2, and manually pull the movable feed rod 2 to check whether the movement of the movable feed rod 2 is flexible and easy. If the bottom surface of the movable feed rod 2 has contacted the wear-resistant pad 4, the thickness of the wear-resistant pad 4 needs to be reduced to ensure that the allowable deformation gap is about 0.05mm. In this way, the movable feed rod 2 can move flexibly when it is not deformed. Once its deformation exceeds 0.05mm during operation, the bottom surface of the movable feed rod 2 will contact the wear-resistant pad 4 to prevent the movable feed rod 2 from further deformation.

[0025] It can be seen that the anti-deformation structure of the movable feeding rod prevents the movable feeding rod 2 from undergoing further deformation by adding a wear-resistant pad 4 to contact the bottom surface of the deformed movable feeding rod 2, thereby ensuring normal feeding of the feeding finger 10. It has a simple structure, is easy to process and assemble, is quick to adjust, has low investment cost, and extends the service life of the mold.

[0026] The above embodiments are only to illustrate the basic principles and characteristics of the utility model. The utility model is not limited by the above embodiments. Without departing from the spirit and scope of the utility model, the utility model has various changes and modifications, which fall within the scope of the utility model to be protected.
