F-shaped clamp and manufacturing method thereof

Abstract

The invention discloses an F-shaped clamp and a manufacturing method thereof, and belongs to an injection molding technology. A main clamp body and a quick-change clamp body of an existing F-shaped clamp are prone to being broken, in the F-shaped clamp, long glass fiber polypropylene is used for replacing nylon glass fibers to manufacture injection molding parts such as a main clamp body, a quick-change clamp body and a release handle of the F-shaped clamp, so that the shrinkage rate of the injection molding parts is reduced from 5% to about 1%, the product surface has no obvious shrinkage deformation, and the material cost is reduced by about 10%; the compressive strength is improved by 1.2 times of the original compressive strength; and light weight is achieved, and product reliability is guaranteed. Moreover, a glue inlet is changed into a flat shape, so that breakage of glass fibers in materials is avoided; the fluidity of the materials in the forming process is enhanced; the forming temperature is reduced, material drying is not needed, and energy is saved by about 10%; and the production efficiency is improved by about 15%.

Description

technical field [0001] The invention belongs to injection molding technology, and in particular relates to an F-shaped clamp and a manufacturing method thereof. Background technique [0002] F-shaped clamp 10 as figure 1 As shown, it includes a main clip body 11, a quick-change clip body 12, a guide rod 13, a booster handle 14, and a release handle 15. 18. Lock the guide rod on the main clip body. By holding the handle of the main clip body 11 and the force handle 14, the guide rod can be moved to the right. The quick-change clip body 12 is moved to the right by the guide rod 13 to approach the main The clip body is used to clamp the object between the main clip body and the quick-change clip body. By holding the handle of the main clip body 11 and the release handle 15, the lock of the booster spring 17 and the booster iron piece 18 to the guide rod can be released. stop, release the clamping, and make the guide rod move to the left. The quick-change clamp body shown in ...

AI Technical Summary

Problems solved by technology

[0003] The existing F-shaped clamps, the main clamp body, quick-change clamp body, and booster handle are mostly made of nylon glass fiber (PA6 GF30). Since nylon glass fiber (PA6 GF30) is filled with 30% long glass fiber, the glass fiber The fiber length is about 10mm. Nylon glass fiber needs to be baked for about 4 hours. During the injection molding process, due to the shearing action of the screw, the remaining length of the glass fiber is greatly reduced, and the remaining length of the glass fiber is proportional to the material strength. The length of the glass fiber is too short, resulting in insufficient material strength, and eventually the main clamp body and quick-change clamp body of the F clamp are easily broken

Moreover, the manufacturing process consumes a lot of energy
