Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a concave mold bending mold which is convenient for demoulding. Background Art

[0002] A bending die is a die used for metal processing, mainly used to bend metal sheets. A bending die usually consists of an upper die and a lower die, where the upper die applies pressure and the lower die is used to support and position the metal sheet. By adjusting the structure and position of the lower die and the upper die, metal sheets of different shapes can be bent to meet the production needs of various products.

[0003] When the existing bending mold is used for processing, the plate is easily stuck in the upper mold or the concave mold under the action of pressure after bending, which is not convenient for demolding. The staff needs to remove it manually. The whole process is time-consuming and labor-intensive, and manual unloading is required, resulting in low work efficiency. Utility Model Content

[0004] In order to solve the above technical problems, a concave die bending mold that is easy to demold is provided. This technical solution solves the problem that during processing with the existing bending molds mentioned in the above background technology, the plate is easily stuck in the upper die or the concave die under the action of pressure after bending, which is inconvenient to demold and requires staff to remove it manually. The whole process is time-consuming and labor-intensive, and manual unloading is required, resulting in low work efficiency.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The mould is adapted to move the mould to a desired position, the mould being arranged on the upper edge of the workbench, the mould being arranged on a track and being arranged on the lower edge of the workbench, and being arranged on a track for movement between the mould ends and the lower edge of the workbench.

[0007] Preferably, an electric push rod is fixedly installed in the middle of the upper end of the workbench, and the output end of the electric push rod is fixedly connected to the lower end of the push plate.

[0008] Preferably, a hydraulic cylinder is fixedly mounted on the upper end of the fixed plate, and an output end of the hydraulic cylinder passes through the upper end of the fixed plate and is fixedly connected to the upper end of the upper mold.

[0009] Preferably, two through holes are formed through the upper end of the upper mold.

[0010] Preferably, a push rod is fixedly connected to the lower end of the fixing plate at a position corresponding to the through hole.

[0011] Preferably, a sliding groove is provided at the rear end of the workbench, and a collection box is fixedly connected to the interior of the sliding groove.

[0012] Preferably, a mounting frame is fixedly connected to the front upper end of the workbench, a cylinder is fixedly mounted on the upper end of the mounting frame, and a discharge plate is fixedly connected to the output end of the cylinder.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] This scheme proposes a concave die bending die that is easy to demold. When the metal sheet is stuck in the upper die due to pressure after being bent and formed, the upper die is driven to rise by a hydraulic cylinder. During the rising process, the push rod will pass through the through hole and push out the sheet stuck on the upper die. If it is stuck in the concave die, the push plate will be pushed up by an electric push rod. During the rising process, the push plate will drive the demolding rod to pass through the demolding hole to push out the sheet stuck in the concave die, so as to facilitate the demolding of the bent sheet.

[0015] In this solution, after the bent sheet is demolded, the sheet will fall on the upper surface of the concave mold. The cylinder pushes the unloading plate to move to the position of the sheet, and then the sheet is pushed from the upper surface of the concave mold to the collection box, thereby realizing automatic unloading and improving work efficiency.

[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0022] Reference Figure 1 and Figure 2 As shown, a concave die bending die for easy demoulding comprises a workbench 1, the upper end of the workbench 1 is fixedly connected to two brackets 13, the upper end of the bracket 13 is fixedly connected to a concave die 14, a demoulding hole 15 is penetrated through the middle of the upper end of the concave die 14, a slide groove 16 is opened on the inner side of the bracket 13, a slider 17 is slidably connected inside the slide groove 16, a push plate 18 is fixedly connected between the two sliders 17, a demoulding rod 20 is fixedly connected to the upper end of the push plate 18 at a position corresponding to the demoulding hole 15, and the diameter of the demoulding rod 20 is the same as the diameter of the demoulding hole 15 Similarly, by pushing the push plate 18, the demoulding rod 20 can pass through the demoulding hole 15 to eject the plate stuck in the concave mold 14. Two support plates 2 are fixedly connected to the edge of the upper end of the workbench 1, and the upper end of the support plate 2 is fixedly connected to the fixed plate 6. The four corners of the upper end of the concave mold 14 are fixedly connected with guide rods 21, and the other end of the guide rod 21 is fixedly connected to the lower end of the fixed plate 6. The outer surface of the guide rod 21 is slidably connected to the upper mold 8. The guide rod 21 guides the upper mold 8 to avoid deviation in the docking between the upper mold 8 and the concave mold 14.

[0023] An electric push rod 19 is fixedly installed in the middle of the upper end of the workbench 1, and the output end of the electric push rod 19 is fixedly connected to the lower end of the push plate 18. The electric push rod 19 is used to drive the push plate 18 to move. A hydraulic cylinder 7 is fixedly installed on the upper end of the fixed plate 6. The output end of the hydraulic cylinder 7 passes through the upper end of the fixed plate 6 and is fixedly connected to the upper end of the upper mold 8. The hydraulic cylinder 7 is used to drive the upper mold 8 to move and provide pressure during bending. Two through holes 9 are penetrated at the upper end of the upper mold 8. A push rod 10 is fixedly connected at the corresponding position of the lower end of the fixed plate 6 and the through hole 9. After bending, the upper mold 8 is driven to rise by the hydraulic cylinder 7. During the movement, the push rod 10 will pass through the through hole 9 to push out the plate stuck in the upper mold 8 to prevent the plate from being stuck in the upper mold 8.

[0024] Reference Figure 1 and Figure 3 As shown, a sliding groove 12 is provided at the rear end of the workbench 1, a collecting box 11 is fixedly connected inside the sliding groove 12, a mounting frame 3 is fixedly connected to the front upper end of the workbench 1, a cylinder 4 is fixedly installed on the upper end of the mounting frame 3, and a discharge plate 5 is fixedly connected to the output end of the cylinder 4.

[0025] Working principle: When the device is in use, the metal sheet to be bent is placed on the upper end of the concave mold 14, and the hydraulic cylinder 7 drives the upper mold 8 to descend and dock with the concave mold 14 to bend the metal sheet. After bending, the hydraulic cylinder 7 drives the upper mold 8 to rise, and the push rod 10 will pass through the through hole 9 during the rising process. At this time, if the metal sheet is stuck in the upper mold 8, it will be pushed out by the push rod 10 and fall on the surface of the concave mold 14. If the metal sheet is stuck in the concave mold 14, the electric push rod 19 will push the push plate 18 up, so that the push plate 18 drives the demoulding rod 20 to pass through the demoulding hole 15 to push the metal sheet out and separate it from the concave mold 14. After the metal sheet is separated from the concave mold 14, the cylinder 4 pushes the unloading plate 5 to move to the position of the metal sheet until the metal sheet falls into the collection box 11.
