Abstract
Description
Technical Field
[0001] The utility model relates to the field of molds, in particular to a guiding structure. Background Art
[0002] The guiding pin is mainly used in molds. Its function is to ensure that the material moves along a predetermined path during stamping or other material processing processes, thereby avoiding material deviation or misalignment. Specifically: through its design and position, the guiding pin helps the material to be correctly aligned in the mold. Especially in stamping operations that require precise control, this helps to improve the quality and consistency of products.
[0003] When the guiding pin is in the middle of the material, both the guiding pin and the punch are positioned by the stripper plate. When the position of the punch needs to be adjusted, the position of the guiding pin will also change simultaneously, resulting in the feeding of the strip material not reaching the accurate position during stamping, leading to unqualified product dimensions. Summary of the Utility Model
[0004] In order to overcome the deficiencies of the prior art, one of the purposes of the utility model is to provide a guiding structure that is simple to operate during installation.
[0005] One of the purposes of the utility model is achieved by adopting the following technical solutions:
[0006] The guiding structure includes a guiding pin, a stripper plate, a stripper plate seat, and a bushing. The stripper plate seat is located above the stripper plate. The stripper plate is provided with a through hole. The bushing is installed on the stripper plate seat and part of the bushing is located in the through hole. The diameter of the through hole is larger than the outer diameter of the bushing, and a gap is formed between the inner wall of the through hole and the outer wall of the bushing. The guiding pin is installed in the bushing.
[0007] Further, the width of the gap is greater than 0.15 mm.
[0008] Further, the stripper plate is parallel to the stripper plate seat.
[0009] Further, the end of the guiding pin extends out of the insert block and protrudes from the stripper plate.
[0010] Further, the guiding structure further includes a push tube. The push tube is installed inside the bushing, and the guiding pin is installed in the push tube.
[0011] Further, the push tube, the bushing, and the guiding pin are coaxially arranged.
[0012] Further, the guiding structure further includes an elastic member. Two ends of the elastic member respectively abut against the push tube and the stripper plate seat.
[0013] Further, the elastic member is a spring.
[0014] Further, the guiding structure further includes a punch, and the punch is installed on the stripper plate.
[0015] Further, the punch is parallel to the pilot pin.
[0016] Compared with the prior art, the guiding structure of the present utility model includes a pilot pin, a stripper plate, a stripper plate seat and a bushing. The stripper plate seat is located above the stripper plate. The stripper plate is provided with a through hole. The bushing is installed on the stripper plate seat and part of the bushing is located in the through hole. The diameter of the through hole is larger than the outer diameter of the bushing, and a gap is formed between the inner wall of the through hole and the outer wall of the bushing. The pilot pin is installed in the bushing. Through the above design, when the position of the stripper plate is moved, due to the gap between the bushing and the stripper plate, when the moving distance of the stripper plate is less than the width of the stripper plate, the positions of the bushing and the pilot pin will not change, and the strip is fed to the accurate position during stamping without affecting the product size.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used herein in the specification of this utility model are for the purpose of describing specific embodiments only and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0024] Please refer to Figures 1 to 3 , the guiding structure is used in the stamping or other material processing process to ensure that the strip 100 moves along a predetermined path, thereby avoiding the offset or misalignment of the strip 100.
[0025] The guiding structure includes a stripper plate 10, a stripper plate seat 20, a bushing 30, a push tube 40, a pilot pin 50, an elastic member 60 and a punch 70.
[0026] The stripper plate 10 is located above the strip 100. The stripper plate 10 is used to mount the punch 70. A through hole 11 is provided on the stripper plate 10, and the through hole 11 is located at a non-edge part of the stripper plate 10. The through hole 11 is used to mount the bushing 30, and the bushing 30 is used to mount the pilot pin 50. The inner diameter of the through hole 11 is larger than the outer diameter of the bushing 30, so that a gap is formed between the through hole 11 and the bushing 30. Therefore, when the stripper plate 10 moves, the pilot pin 50 does not move, and thus the feeding position of the strip 100 is not affected.
[0027] Specifically, the through hole 11 is cylindrical, the bushing 30 is also cylindrical, and the width of the gap between the bushing 30 and the through hole 11 is greater than 0.15 mm.
[0028] The stripper plate seat 20 is located above the stripper plate 10, and the stripper plate seat 20 is parallel to the stripper plate 10.
[0029] The bushing 30 is used to mount the pilot pin 50, and the bushing 30 and the pilot pin 50 are coaxially arranged.
[0030] The ejector tube 40 is installed between the bushing 30 and the pilot pin 50. When the pilot pin 50 guides the strip 100, the strip 100 hanging on the pilot pin 50 is pushed down by the ejector tube 40 to ensure normal production. Specifically, the end of the bushing 30 extends out of the ejector tube 40, and the ejector tube 40 is coaxially arranged with the bushing 30.
[0031] Both ends of the elastic member 60 are respectively in contact with the stripper plate seat 20 and the ejector tube 40. Specifically, the elastic member 60 is a spring, and the elastic member 60 is sleeved on the upper part of the pilot pin 50 and located at the top of the ejector tube 40.
[0032] The punch 70 is installed on the stripper plate 10 and is coaxially arranged with the pilot pin 50.
[0033] When using the guiding structure, when it is necessary to move the stripper plate 10, since the inner diameter of the through hole 11 is larger than the outer diameter of the bushing 30, a gap is formed between the through hole 11 and the bushing 30. Therefore, when the moving distance of the stripper plate 10 is less than the width of the gap, the pilot pin 50 does not move, so it does not affect the feeding position of the strip 100. During stamping, the strip 100 is fed to the accurate position without affecting the product size. When the pilot pin 50 guides the strip 100, the strip 100 hanging on the pilot pin 50 is pushed down by the ejector tube 40 to ensure normal production.
[0034] The above embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can be made. These are all equivalent modifications and evolutions made to the above embodiments based on the essential technology of the present utility model, and these all belong to the protection scope of the present utility model.
