Problems solved by technology

[0002] The cross-section of the refrigerator door is usually U-shaped, and its production method usually adopts stamping forming. However, the existing stamping forming process can only stamp the refrigerator door into a U-shape, and the refrigerator door cannot be folded inward. The existing refrigerator door folding The edge structure is complex and easy to strain the folded edge

Abstract

The invention relates to a refrigerator door plate bending die. The refrigerator door plate bending die comprises an upper die rib plate, a lower die plate, an upper die plate, a lower die deck plate, lower die bending bars, driving blocks, upper die mounting bases, reset rear stopping bars, reset guide pillars and reset springs. The outer sides of the lower die bending bars are provided with bending surfaces. The other ends of the reset guide pillars are connected with upper die bending bars. The inner sides of the upper die bending bars are provided with bending inclined surfaces. The top surfaces of the inner sides of the driving blocks are provided with driving surfaces. The bottoms of the outer sides of the upper die bending bars are provided with driving inclined surfaces. The upper die plate is provided with pressing plate guide pillars and a material pressing plate. The outer sides of the lower die bending bars are provided with linear bearings and discharging guide pillars. Part returning strips and material returning springs are arranged at the tops of the discharging guide pillars. According to the refrigerator door plate bending die, the driving blocks drive the upper die bending bars to move along the edges of the lower die bending bars, so that an edge folding structure for a refrigerator door is simple; the part returning strips are arranged on the sides of the two longest lower die bending bars, so that discharging is facilitated; and positioning blocks on the part returning strips prevent interference between the upper die bending bars and the part returning strips.

Description

technical field [0001] The invention relates to a refrigerator door production mold, in particular to a refrigerator door panel bending mold. Background technique [0002] The cross-section of the refrigerator door is usually U-shaped, and its production method usually adopts stamping forming. However, the existing stamping forming process can only stamp the refrigerator door into a U-shape, and the refrigerator door cannot be folded inward. The existing refrigerator door folding The edge structure is complex and easy to strain the folded edge. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a refrigerator door panel bending mold. [0004] The technical solution adopted by the present invention to solve the technical problems is: a refrigerator door panel bending mold, including upper mold ribs, lower template, and upper template, the lower template is provided with a lower mold installatio...
