Description

Technical Field

[0001] This utility model relates to the field of automotive stamping die technology, specifically to a lateral core-pulling and resetting structure for automotive stamping dies. Background Technology

[0002] In the automotive stamping process, some parts become automotive components directly after stamping, while others require further processing such as welding, machining, or painting before becoming automotive components. There are many types of automotive stamping parts, such as shock absorber stamping parts like spring trays, spring seats, spring brackets, end caps, seals, compression valve covers, compression valve sleeves, oil seal seats, bottom covers, dust covers, impellers, oil cylinders, lugs, and brackets.

[0003] In the existing technology, friction causes wear and tear on parts during the core-pulling and reset process of molds, resulting in unstable movement of the parts. The core-pulling operation can usually only be performed on the mold from one angle, and it is not possible to pull and reset the mold cores at different horizontal angles. Therefore, we propose a lateral core-pulling and reset structure for automotive stamping molds. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a side core-pulling and reset structure for automotive stamping parts dies. This structure can effectively reduce friction and wear during the core-pulling and reset process, and can effectively reset the cores at different horizontal angles on the side of the die. This can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lateral core-pulling and resetting structure for automotive stamping die, comprising a mounting plate, an angle adjustment assembly, a lubrication assembly, and a power assembly;

The dovetail-shaped slide two is fixedly connected to the upper center of the mounting plate. The dovetail-shaped slide two has cavities on its inner left and right sides. Multiple oil outlets are opened on the inner left and right sides of the dovetail-shaped slide two and the cavities. Multiple rectangular collection grooves are opened on the lower inner end of the dovetail-shaped slide two. The liquid level detector is fixedly connected to the upper rear center of the dovetail-shaped slide two. The probe of the liquid level detector is inside the cavity. The dovetail-shaped slider is slidably connected to the inner side of the dovetail-shaped slide two.

[0008] The mold core is guided by the sliding cooperation between the dovetail slide block and the dovetail slider.
