[0002] For sheet metal structures such as air conditioner chassis, holes need to be drilled in the folded side walls around the chassis to facilitate fixing to other structures. Currently, many processes use machining to punch these holes, punching holes one side at a time around the chassis. Therefore, this processing method is inefficient and increases labor costs during production. Utility Model Content

[0003] The purpose of this utility model is to provide a side punching mold for an air conditioner chassis that can solve at least one of the above problems.

[0004] According to one aspect of the present invention, a side punching mold for an air conditioner chassis is provided, including a cutting tool, a sliding device, a punch, and an upper mold base, an upper pad, an upper ejector plate, a lower ejector plate, a lower pad, a lower mold base, a lower foot, and a lower base plate arranged from top to bottom. The sliding device is disposed on the lower pad plate, the upper ejector plate and the lower ejector plate are correspondingly disposed, the punch is connected to the sliding device, the punch is located on one side of the lower ejector plate, one end of the cutting tool is fixed to the upper mold base, and the other end cooperates with the sliding device, and a float is provided on the lower ejector plate, the top of the float being able to extend beyond the upper end surface of the lower ejector plate.

[0005] The beneficial effects of this utility model are as follows: by providing a punch on the sliding device, when the mold is closed, the inserter acts on the sliding device, pushing the punch to move inward, thereby punching holes on the side of the air conditioner chassis without the need for additional machining, thus improving the efficiency of side punching; at the same time, by providing a float, the air conditioner chassis can be limited, thereby enabling the workpiece to be quickly positioned and installed on the lower stripper plate, which helps to improve work efficiency and ensure the accuracy of each punch.

[0006] In some embodiments, there are multiple floats, and each float is provided with a first spring below it. One end of the first spring is fixed to the lower mold base, and the other end is connected to the float. Thus, by providing the first spring, during demolding, the rebound force of the first spring pushes the air conditioner chassis upward, realizing the separation of the air conditioner chassis from the lower demolding plate, which facilitates demolding.

[0007] In some implementations, the sliding device is located around the lower ejector plate. This allows for punching holes on all sides of the chassis, significantly improving work efficiency.

[0008] In some embodiments, the sliding device includes a slider, a second spring, and a support block. The support block is fixed to a lower pad, one end of the second spring is fixed to the support block, and the other end is connected to the slider. The inserter engages with the slider, and the punch is fixed to the slider. Thus, the slider can move by engaging with the inserter, facilitating side punching by the punch.

[0009] In some embodiments, the inserter has a first inclined surface on one side, and the slider has a second inclined surface on one side. The first and second inclined surfaces are inclined in the same direction and can fit together. Thus, through the cooperation of the two inclined surfaces, the inserter can easily act on the slider, thereby driving the slider to move.

[0010] In some embodiments, a slide rail is provided on the lower pad, and a groove is provided on the bottom of the slider, which cooperates with the slide rail. Thus, by providing a slide rail, the slider can be moved smoothly and easily. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings.

[0016] Reference Figures 1-2 The side punching mold for an air conditioner chassis includes a cutting tool 1, a sliding device 2, a punch 3, and, arranged from top to bottom, an upper mold base 4, an upper pad 5, an upper ejector plate 6, a lower ejector plate 7, a lower pad 8, a lower mold base 9, a lower support foot 10, and a lower base plate 20. The sliding device 2 is mounted on the lower pad 8. The upper ejector plate 6 and the lower ejector plate 7 are correspondingly arranged. The punch 3 is connected to the sliding device 2 and is located on one side of the lower ejector plate 7. One end of the cutting tool 1 is fixed to the upper mold base 4, and the other end cooperates with the sliding device 2. The lower ejector plate 7 is provided with a float 30, the top of which can extend beyond the upper surface of the lower ejector plate 7. The sliding device 2 is located around the lower ejector plate 7, so the punches 3 mounted on the sliding device 2 can punch holes on each side of the air conditioner chassis, achieving side punching in multiple directions at once, greatly improving processing efficiency.

[0017] There are multiple floats 30, and each float 30 is provided with a first spring 40 below it. One end of the first spring 40 is fixed to the lower mold base 9, and the other end is connected to the float 30. In order to facilitate the installation of the first spring 40, mounting holes are provided on the lower pad 8 and the lower mold base 9 to limit the direction of the first spring 40.

[0018] When the mold is in the open state, each float 30 is higher than the lower ejector plate 7. When the workpiece is placed, the corresponding position of the workpiece is pressed against and pressed above the float 30. The float 30 can facilitate the quick positioning and placement of the workpiece.

[0019] When the air conditioning chassis (such as Figure 3 and Figure 4 When side punching is required, the air conditioner chassis is placed on the lower ejector plate 7, and the workpiece is positioned by the float block 30 to achieve product placement. Subsequently, the upper mold base 4, upper pad 5, and upper ejector plate 6 move downwards, causing the inserter 1 to move downwards as well; the inserter 1 acts on the sliding device 2, and the sliding device 2 drives the punch 3 to approach the lower ejector plate 7. As the inserter 1 moves downwards, when the upper ejector plate 6 moves down to the lower ejector plate 7, the punch 3 acts on the side of the lower ejector plate 7, which can punch the side of the air conditioner chassis.

[0020] When the upper ejector plate 6 acts downward on the workpiece on the lower ejector plate 7, the first spring 40 is pressed down under the action of the workpiece, and the float 30 moves down, so that the workpiece is pressed tightly against the lower ejector plate 7, and the first spring 40 is in a compressed state. After the punch 3 completes punching the workpiece, the upper die base 4 drives the upper ejector plate 6 to move upward to open the die; when the upper ejector plate 6 moves upward, the pressing action on the workpiece is released. At this time, under the action of the rebound force of the first spring 40, the float 30 is pushed upward, and the float 30 pushes the workpiece upward, so that the workpiece is separated from the lower ejector plate 7, realizing demolding. Then, the worker can remove the punched workpiece to complete the processing, which greatly improves the efficiency of side punching.

[0021] The sliding device 2 includes a slider 21, a second spring 22 and a support block 23. The support block 23 is fixed on the lower pad 8. One end of the second spring 22 is fixed on the support block 23 and the other end is connected to the slider 21. The inserter 1 cooperates with the slider 21 and the punch 3 is fixed on the slider 21.

[0022] The inserter 1 has a first inclined surface 11 on one side and a second inclined surface 211 on one side of the slider 21. The first inclined surface 11 and the second inclined surface 211 have the same inclination direction and can fit together.

[0023] The lower pad 8 is provided with a slide rail 81, and the bottom of the slider 21 is provided with a slide groove, which cooperates with the slide rail 81.

[0024] Specifically, as the inserter 1 moves downward with the upper mold base 4, the first inclined surface 11 gradually comes into contact with the second inclined surface 211 of the slider 21. Under the guidance of the first inclined surface 11, the slider 21 is pushed to move downward to the ejector plate 7 side, ultimately driving the punch 3 to punch holes on the product from the side. Because a slide rail 81 is provided, the slider 21 moves along the slide rail 81, improving the smoothness of the slider 21's movement.

[0025] When the slider 21 moves to the side of the lower ejector plate 7, the second spring 22 is gradually stretched, so that the second spring 22 is in a stretched state; when the mold opens, the inserter 1 moves upward, releasing the limit of the inserter 1 on the slider 21. At this time, the second spring 22 pulls back, driving the slider 21 to pull back and return to the initial state, so that the slider 21 can drive the punch to punch the next side.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
