Forming mold for back panel of refrigerator

Abstract

The invention discloses a refrigerator back plate forming mold and a forming process. The mold comprises an upper fixing plate, a forming concave mold, an upper mold and a lower mold, wherein the upper fixing plate is connected with the forming concave mold and the upper mold through a telescopic cylinder, the upper template is arranged above the lower template; the upper fixing plate is connectedwith the forming concave mold through a first telescopic cylinder, and the two ends of the upper fixing plate are connected with the upper mold through a second telescopic cylinder. According to therefrigerator back plate forming mold and forming process, a sheet metal panel can be subjected to one-time machining forming to form a finished product refrigerator back plate, the structure error generated in the production process of the refrigerator back plate is reduced, and the production efficiency is improved; and meanwhile, in the whole production forming process, the forming concave moldis always tightly pressed against the sheet metal panel, the position of the sheet metal panel in the production process is prevented from shifting, and the quality of the finished product refrigerator back plate is further guaranteed.

Description

technical field [0001] The invention belongs to the technical field of sheet metal parts processing, and in particular relates to a forming mold and a forming process for a refrigerator back panel. Background technique [0002] The refrigerator back panel in the prior art is a sheet metal product, which is mainly processed and formed through processes such as drawing, punching and bending. During the drawing process, the sheet metal raw material is often caused by uneven force on each part. During the drawing process, the position of the sheet metal material is shifted, which reduces the product quality of the produced back panel, makes the assembly of the back panel difficult, and even causes the back panel to fail to meet the requirements and cannot be used in severe cases. [0003] The production of the traditional refrigerator back panel is carried out separately. This production method greatly reduces the production efficiency and increases the production cost of the en...

Problems solved by technology

[0002] The refrigerator back panel in the prior art is a sheet metal product, which is mainly processed and formed through processes such as drawing, punching and bending. During the drawing process, the sheet metal raw material is often caused by uneven force on each part. During the drawing process, the position of the sheet metal material is shifted, which reduces the product quality of the produced back panel, which makes the assembly of the back panel difficult, and even causes the back panel to fail to meet the requirements and cannot be used in severe cases.

[0003] The production of the traditional refrigerator back panel is carried out separately. This production method greatly reduces the production efficiency and increases the production cost of the enterprise. Moreover, when each process is carried out separately, the processing machinery needs to be checked every time. Adjustment, due to the errors between the various processing machines and human errors in the processing process, it is easy to lead to low product quality. In order to solve this problem, a refrigerator back panel forming mold and forming process are provided. The present invention provides the following technical solutions
