Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and specifically relates to a secondary forming mold for the tail beam of a heavy truck. Background Technology

[0002] The tail beam of heavy trucks requires secondary forming, which is generally done by a bending machine. It needs to be bent twice on the bending machine. Because the product is too bulky, it needs to be moved back and forth twice during the loading and unloading process, which increases the labor intensity of the operators and affects the production efficiency.

[0003] There are some mold structures for secondary molding, but due to the significant differences in product structures, it is difficult to achieve universality. Utility Model Content

[0004] This utility model provides a secondary forming mold for the tail beam of a heavy truck, which can solve the problems pointed out in the background art.

[0005] A secondary forming mold for a heavy-duty truck tail beam includes an upper mold structure and a lower mold structure. The upper mold structure includes an upper template, an upper mold block connected to the upper template, and an upper mold insert on the bottom surface of the upper mold block. The lower mold structure includes a lower template and a lower mold frame connected to the lower template. The lower mold frame has a mold cavity, and a material support plate is slidably disposed in the mold cavity, allowing the material support plate to slide back and forth along the depth direction of the mold cavity. The lower end of the material support plate is connected to a sliding connecting column, which is used to connect to a press. A mold cavity insert is disposed on the inner wall of the mold cavity.

[0006] Preferably, the two ends of the material support plate are slidably connected to the lower mold frame via sliders.

[0007] Preferably, the upper model block includes several unit blocks, and the lower model frame includes several unit frames.

[0008] Beneficial effects: This utility model provides a secondary forming mold for heavy truck tail beams, which is applicable to the secondary forming of heavy truck tail beams. It has the advantages of convenient operation, high precision, and high production efficiency, thereby reducing production costs and improving product quality. Attached Figure Description

Detailed Implementation

[0013] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0014] Example 1:

[0015] like Figure 1-2 As shown in the figure, the present invention provides a secondary forming mold for a heavy truck tail beam, including an upper mold structure 1 and a lower mold structure 2, with a guide structure between them. The guide structure includes a guide sleeve and a guide post. This structure is a conventional mold structure and will not be described in detail. The upper mold structure 1 includes an upper template 11, an upper mold block 12 connected to the upper template 11, and an upper mold insert 13 on the bottom surface of the upper mold block 12. The lower mold structure 2 includes a lower template 21 and a lower mold frame connected to the lower template 21. 22. A mold cavity 23 is provided inside the lower mold frame 22. A material support plate 24 is slidably provided inside the mold cavity 23, so that the material support plate 24 slides back and forth along the depth direction of the mold cavity 23. Specifically, the two ends of the material support plate 24 are slidably connected to the lower mold frame 22 through sliders 27. The lower end of the material support plate 24 is connected to a sliding connecting column 25. The sliding connecting column 25 is used to connect to a press and is driven to slide back and forth by the press. A mold cavity insert 26 is provided on the inner wall of the mold cavity 23.

[0016] The upper mold block 12 includes several unit blocks 121, and the lower mold frame 22 includes several unit frames 221, which can be connected by bolts to form an integral structure, making it easy to replace and adjust the molding specifications.

[0017] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
