Disposable side pushing and flattening structure of the upper mold of the middle beam of the refrigerator

Abstract

The invention belongs to the field of a stamping die, and particularly relates to a disposable side-pushing and planishing structure for an upper die of a center beam of a refrigerator. The disposable side-pushing and planishing structure comprises a stamping progressive die, wherein a stripping plate insert is mounted in the center of the stripping plate of the stamping progressive die; horizontal guide rails are arranged on the two sides of the stripping plate insert respectively, and fixed to the stopping baffle of the stamping progressive die; upper die side-sliding blocks are mounted on the guide rails respectively; the upper die side-sliding blocks can slide along the guide rails in a side direction; the upper die side blocks are connected with and hung on the stopping baffle through shoulder bolts; reset springs used for stripping materials are mounted between the upper die side-sliding blocks and the stripping plate insert; slotting tools are arranged outside the upper die side-sliding blocks; the upper side-sliding blocks are matched with the slotting tools through respective inclined planes in a sliding manner; a lower die insert is mounted in the center of the lower base plate of the stamping progressive die; the lower die insert corresponds to the stripping plate insert in an up-down direction; lower die balancing blocks are arranged on the two sides of the lower die insert respectively, and fixed onto the lower base plate.

Description

technical field [0001] The invention belongs to the field of stamping dies, and more specifically relates to a disposable side pushing and flattening structure of an upper die of a middle beam of a refrigerator. Background technique [0002] With the development of the refrigerator industry, the entire industry has higher and higher requirements for technology. In an era of increasingly fierce competition, high-speed and efficient production has been expected by various manufacturers. Refrigerator center beam (such as figure 1 (shown) is an important part, and the production volume is very large. Using some traditional mold structures, there are too many processes, which can no longer meet the requirements. The molding process currently used is: using a knife mold structure, forming one side at a time, and doing it in many steps, the efficiency is low, and the assembly line is often broken due to shortage. [0003] Therefore, many manufacturers consider using progressive d...

Problems solved by technology

Refrigerator center beam (such as figure 1 (shown) is an important part, and the production volume is very large. Some traditional mold structures are used, and there are too many processes, which can no longer meet the requirements.

The molding process currently used is: using a knife mold structure, forming one side at a time, and doing it in many steps, the efficiency is low, and the assembly line is often broken due to shortage

[0003] Therefore, many manufacturers consider using progressive dies for production. However, since the middle beam of the refrigerator is an exterior part, the burr direction of the product has requirements and can only be formed downwards. Therefore, there are certain difficulties in side push forming.

The traditional method is generally to install the lower mold on the side pushing block, install the inserting knife on the upper mold, and the inserting knife pushes the slider of the lower mold to form inwardly, but this structure can no longer be used here
