Description

Technical Field

[0001] This utility model belongs to the field of lower connecting plate processing technology, and relates to a mold assembly for punching processing of lower connecting plates. Background Technology

[0002] As an essential component of motorcycles, the lower connecting plate currently uses laser cutting for punching the shock absorption holes. However, during the actual processing, punching debris may remain inside the workpiece cavity. If this debris is not cleaned up in time after cutting, it can easily affect subsequent assembly and even cause wear. Therefore, manual inspection is required after processing. However, because the debris is relatively small, it is difficult to identify with the naked eye. Touching it by hand may cause injury. Also, if it is found to be adhered, it needs to be treated, making the process relatively cumbersome. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a mold assembly for secondary forging after laser cutting.

[0004] The objective of this utility model can be achieved through the following technical solution: A mold assembly for punching a lower connecting plate, comprising a mold body and a lower plate body disposed within the mold body, characterized in that the mold body comprises a base, a mold unit having an assembly cavity for mounting the lower connecting plate and facilitating its secondary punching, a lower template disposed on the base for mounting the mold unit, and a stamping unit for punching, the mold unit comprising an upper mold shell and a lower mold shell assembled with the upper mold shell, wherein the upper mold shell has an axial through hole on its upper end face at the damping hole of the lower connecting plate, the inner diameter of the through hole being larger than the outer diameter of the damping hole, and the stamping unit comprising a lower pressure plate and a stamping rod disposed on and connected to the lower pressure plate for punching.

[0005] In the aforementioned mold assembly for punching holes in a lower platen, an adjustment unit is provided between the lower platen and the base, which is connected to the base and used to adjust the height of the lower platen and facilitate waste removal. This adjustment unit includes a lifting motor with a lifting rod, several support rods, a base plate, a storage block, and an assembly block. The base plate is mounted on and connected to the base. The two ends of the support rods are respectively connected to the base plate and the assembly block. The lifting motor is mounted on the base plate and connected to the base plate. The upper surface of the assembly block has an axially inwardly recessed through-hole groove for the lifting motor to extend into. The lifting rod in the lifting motor is connected to the lower platen through this through-hole groove, allowing the lifting rod to move the lower platen. The number of storage blocks is the same as the number of shock-absorbing holes. The storage blocks are connected to the base via connecting rods, and the storage blocks extend into corresponding through-holes via connecting rods.

[0006] In the aforementioned mold assembly for punching holes in a lower connecting plate, the storage block is arranged in a cylindrical structure, and the upper end face of the storage block has an axially recessed storage groove, the inner diameter of which is larger than the outer diameter of the shock-absorbing hole.

[0007] In the aforementioned mold assembly for punching holes in a lower connecting plate, the lower pressure plate is connected to the base via several guide rods.

[0008] Compared with existing technologies, the mold assembly used for punching the lower connecting plate improves the pass rate by setting up a mold to further punch and improve the lower connecting plate after laser cutting. Attached Figure Description

[0010] In the diagram, 1 is the base; 2 is the upper mold shell; 3 is the lower mold shell; 4 is the lower pressure plate; 5 is the stamping rod; 6 is the lifting motor; 7 is the support rod; 8 is the base plate; 9 is the storage block; and 10 is the assembly block. Detailed Implementation

[0011] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0012] like Figure 1As shown, the mold assembly for punching the lower connecting plate includes a mold body and a lower plate body disposed within the mold body. The mold body includes a base 1, a mold unit with an assembly cavity for mounting the lower connecting plate and facilitating its secondary punching, a lower template disposed on the base 1 for mounting the mold unit, and a punching unit for punching. The mold unit includes an upper mold shell 2 and a lower mold shell 3 formed by splicing the upper mold shell 2. The upper mold shell 2 has an axial through-hole on its upper end face at the vibration damping hole of the lower connecting plate. Through holes in the upper die shell 2 and lower die shell 3, the inner diameter of which is larger than the outer diameter of the shock-absorbing hole, the stamping unit includes a lower pressure plate 4 and a stamping rod 5 disposed on and connected to the lower pressure plate 4 for punching holes. The stamping rod 5 is located directly above the corresponding shock-absorbing hole. An adjustment unit is provided between the lower die shell and the base 1, which is connected to the base 1 and used to adjust the height of the lower die shell and facilitate waste removal. The adjustment unit includes a lifting motor 6 with a lifting rod, several support rods 7, a base plate 8, and a storage block 9. The assembly block 10 and the base plate 8 are mounted on and connected to the base 1. The two ends of several support rods 7 are respectively connected to the base plate 8 and the assembly block 10. A lifting motor 6 is mounted on and connected to the base plate 8, and is located at the center of the base plate 8. The upper surface of the assembly block 10 has an axially inwardly recessed through-hole groove for the lifting motor 6 to extend into. This through-hole groove connects the lifting rod in the lifting motor 6 to the lower template, allowing the lifting rod to move the lower template.
