Brake forming mold for door casing of refrigerator

Abstract

The invention discloses an electric refrigerator door shell bending forming die. The bending forming die comprises an upper die plate and a lower die plate; the upper die plate is symmetrically fixed with two upper drive blocks and two upper die bending strips from the outside to the inside, and the outside surface and the inside surface of each drive block are respectively provided with a first oblique plane and a second oblique plane which are arranged downwards; the lower die plate is symmetrically provided with two sliders which are slidably arranged in a main slideway, each slider is fixed with lower drive blocks and lower die bending strips from the outside to the inside, and the inside surface of each lower drive block is provided with a third oblique plane which is arranged upwards and opposite to the first oblique plane; meanwhile, each slider is also provided with a sub-slideway which is positioned between the lower drive block and the lower die bending strip, the sub-slideway is internally and slidably provided with a bending strip, the outside surface of which is provided with a fourth oblique plane which is arranged upwards and opposite to the second oblique plane, and side surfaces of the lower die bending strips are provided with bending concave parts which are matched with the bending strips. The bending forming die can once complete the bending forming of the electric refrigerator door shell, thus improving the production efficiency.

Description

technical field [0001] The invention relates to a bending forming mold for a door shell of a refrigerator. Background technique [0002] The cross-sectional shape of the refrigerator door shell is usually as follows figure 1 As shown, the two ends of the main body 14 have two side edges 15 with arc-curved transition, and the bottom of each side edge 15 also has an inward-facing flange 16 . At present, when processing this kind of refrigerator door shell, since there is no mold capable of one-time bending and forming, it is necessary to use multiple sets of conventional molds to process in several steps, which is time-consuming and laborious, and the equipment cost is large, and the production efficiency is low. Contents of the invention [0003] The purpose of the present invention is to provide a bending forming mold for the refrigerator door shell, which can complete the bending and forming of the refrigerator door shell at one time, greatly reduce the production proces...
