Description

Technical Field

[0001] This utility model relates to the field of automotive exterior panel processing technology, and in particular to an automotive exterior panel trimming mold. Background Technology

[0002] Chinese patent document CN211679508U discloses a trimming mold for automotive exterior body panels, comprising a die holder, a punch holder, and a mounting frame. The mounting frame includes a base plate, side plates, and a top plate. The die holder is mounted on the upper part of the base plate, and the punch holder is movably mounted on the inner sides of the two side plates. Support blocks are fixed on opposite surfaces of the side plates, and guide posts are vertically fixed between the support blocks and the top plate. Guide blocks are also fixed on the outer side of the punch holder. A positioning groove is provided on the top surface of the base plate, and positioning blocks corresponding to the positioning groove are fixed at the four corners of the bottom of the die holder. The mold of this invention is installed using the mounting frame. After the lower die holder is positioned and installed, it is fixed using a manual fastening assembly, making installation and disassembly convenient. The top punch holder moves up and down along the guide posts on both sides, ensuring accurate positioning and precise trimming. This avoids the problem of poor trimming effect and mold damage due to deviation between the punch holder and the die holder.

[0003] After investigation and analysis, the patent has the following drawbacks in actual use:

[0004] The device only allows for the disassembly and replacement of the die holder, while the punch holder is fixed. Therefore, the fixed upper die limits the adaptability to body panels of different car models. In addition, the location of the trimming knife is not specifically described, so it is uncertain whether the trimming knife needs to be replaced when trimming different body panels.

[0005] In summary, this application proposes a trimming mold for automotive exterior body panels to solve the aforementioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a trimming mold for automotive exterior body panels, which can solve the problem that only the die holder can be disassembled and replaced, while the punch holder is fixed. Therefore, the fixed upper mold limits the adaptability to body panels of different models. At the same time, the location of the trimming blade is not specifically described, so it is uncertain whether the trimming blade needs to be replaced when trimming different body panels.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a trimming mold for automotive exterior body panels, comprising:

[0008] The workbench has multiple sets of columns fixedly installed on its top, and a movable plate is slidably installed on the columns.

[0009] The mounting assembly is mounted on the movable plate. The mounting assembly includes a mounting base, a trimming knife, a connecting plate, and a hinge plate. The top of the mounting base is fixedly mounted to the bottom of the movable plate. The trimming knife is fixedly mounted on the bottom of the mounting base. The connecting plates are fixedly mounted on the front and rear sides of the mounting base. The top of the connecting plate is hingedly mounted to a hinge plate.

[0010] The positioning assembly is set on the worktable. The positioning assembly includes guide rods, positioning posts and springs. Multiple sets of guide rods are fixedly installed on the bottom of the moving plate. An opening is opened on the top of the worktable. A positioning post is slidably installed in the opening. A spring is fixedly installed on the bottom of the positioning post.

[0011] Preferably, a top plate is fixedly installed on the top of the column, and a hydraulic rod is fixedly installed on the top of the top plate. The free end of the hydraulic rod passes through the top plate and is fixedly installed on the top of the movable plate.

[0012] Preferably, the bottom of the hinge plate contacts the top of the moving plate. The moving plate and the hinge plate have a connected mounting hole, into which a bolt is installed. The detachable design of the trimming knife makes tool replacement simpler and faster. Since the tool can be easily disassembled and replaced after wear or damage, downtime is reduced and production efficiency is improved. For applications requiring regular tool replacement, this design significantly reduces maintenance costs and production interruption time. The hinge plate can be rotated through its hinge connection with the connecting plate. The hinge plate's mounting on the moving plate ensures the tool remains stably in its predetermined position, preventing positional shifts during operation. The bolts securing the hinge plate and the moving plate further enhance the stability of the trimming knife, preventing tool loosening or failure due to vibration or external forces, thereby improving the precision of the trimming process.

[0013] Preferably, the positioning component further includes a fixing frame, which is fixedly installed at the bottom of the worktable. The other end of the spring is fixedly installed to the inner bottom of the fixing frame. A damper is provided inside the spring. The positioning post can ensure the stability of the outer cover during the trimming process, avoiding the workpiece from shifting or shaking during the trimming process. The guide rod can help the positioning post to be accurately positioned by the downward force, ensuring the consistency of the trimming position. Through the rebound force provided by the spring and the downward action of the guide rod, it can ensure that the positioning post provides uniform pressure during the trimming process, avoiding uneven pressure that may cause workpiece deformation or uneven trimming. It can also make the positioning post have a certain elasticity during mold operation, making the contact between the workpiece and the mold more stable.

[0014] Preferably, a lower mold is provided on the top of the workbench, and positioning plates are fixedly installed on both sides of the lower mold. The workbench and the positioning plates are provided with interconnected mounting holes II, and bolts are provided in the mounting holes II. A knife groove is provided on the top of the lower mold, and the mounting holes II are used for positioning the mold.

[0015] Preferably, the mounting base, trimming knife, and lower mold are located on the same center line, which helps to improve the trimming accuracy.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) The trimming mold for automotive exterior panels uses a mounting base, trimming knife, connecting plate and hinge plate in combination. The detachable design of the trimming knife makes the replacement of the knife easier and faster. Since the knife can be easily disassembled and replaced after wear or damage, downtime is reduced and production efficiency is improved. For application scenarios that require regular replacement of the knife, this design can significantly reduce maintenance costs and production interruption time. The hinge plate can be rotated by the hinge of the connecting plate and the hinge plate. The hinge plate is locked on the moving plate to ensure that the knife is stably kept in the predetermined position and prevents position displacement during operation. The fixation of the hinge plate and the moving plate by bolts further enhances the stability of the trimming knife and avoids the knife from loosening or failing due to vibration or external force, thereby improving the accuracy of the trimming process.

[0018] (2) The trimming mold for automotive exterior panels uses a combination of guide rods, positioning pins, fixing brackets and springs. The positioning pins can ensure the stability of the position of the exterior panels during the trimming process, avoiding the workpiece from shifting or shaking during the trimming process. The guide rods can help the positioning pins to be accurately positioned by the downward force, ensuring the consistency of the trimming position. The spring force and the downward force of the guide rods can ensure that the positioning pins provide uniform pressure during the trimming process, avoiding uneven pressure that could cause workpiece deformation or uneven trimming. The positioning pins can also have a certain elasticity during mold operation, making the contact between the workpiece and the mold more stable. Attached Figure Description
