Problems solved by technology
[0002] Some equipment panel structures are in the middle plane, with arc bends on both sides, and vertical right-angle bends on the sides of the arc bends. Generally, bending machines are used to bend bit by bit, and the forming effect after bending is poor, and A long time will eventually lead to a sharp increase in the number of defective products
Later, I tried mold compression molding, but because the top of the curved part has a vertical right-angled part for locking the screw, when the curved part is formed, it will be directly hooked on the mold, which is not easy to demould, and because The curved protruding part of the curved part is located in the middle of the curved part of the lower mold, so when the curved parts on both sides of the lower mold cannot be avoided, the finished product cannot be taken out, making it unusable

The invention discloses an automatic-demolding bending mold. The bending mold comprises an upper mold plate and a lower mold plate. Two slopes of the upper mold plate are each provided with a plurality of dovetail grooves. Dovetail sliding blocks moving along the directions of the dovetail grooves are arranged in the dovetail grooves. The dovetail sliding blocks are connected with an upper bending mold body. Second slopes matched with the slopes of the upper mold plate are arranged on the upper bending mold body. Stop blocks are further arranged at the upper portions of the surfaces of the dovetail sliding blocks and used for limiting. Baffles are arranged on the two sides of the lower mold plate respectively. A lower bending mold body is arranged between the baffles and the lower mold plate. An arc-shaped face is arranged at the bottom of the lower bending mold body, and a step part is arranged at one end of the lower bending mold body. A concave part is arranged on one side of the bottom of the lower mold plate, and the step part is matched with the concave part. The lower mold plate is connected with a lower mold base through springs. The bending mold is simple in structure and reasonable in design, one-time punch molding can be carried out, and automatic falling can be achieved.

technical field [0001] The invention relates to the field of bending molds, in particular to a bending mold for automatic demoulding. Background technique [0002] Some equipment panel structures are in the middle plane, with arc bends on both sides, and vertical right-angle bends on the sides of the arc bends. Generally, bending machines are used to bend bit by bit, and the forming effect after bending is poor, and A long time will eventually lead to a sharp increase in the number of defective products. Later, I tried mold compression molding, but because the top of the curved part has a vertical right-angled part for locking the screw, when the curved part is formed, it will be directly hooked on the mold, which is not easy to demould, and because The arc-shaped protruding part of the curved part is located in the middle of the arc-shaped part of the lower die, so when the arc-shaped parts on both sides of the lower die cannot be avoided, the finished product cannot be ta...
