Description

Technical Field

[0001] This utility model relates to a flanging mold, and more particularly to a flanging mold for an air conditioner chassis. Background Technology

[0002] For sheet metal structures such as air conditioner chassis, grooves and protrusions need to be formed on the chassis to improve its strength, and flanging is also required to facilitate cooperation with other structures. For example, application number 202123327826.3 discloses a sheet metal flanging die. To solve the problem of material jamming, it has four sliding rods, four first springs, and a feeding block. The four first springs lift the sheet metal to avoid jamming, but the overall structure is relatively complex. However, this type of flanging die frequently stamps the product under high pressure. Therefore, with the increase of usage time, the first springs are prone to deformation or uneven force distribution among the four first springs, resulting in uneven stamping force on the product and affecting the forming quality. At the same time, when placing the sheet metal on this type of die, the operator's experience is required to place the sheet metal as centered as possible, which is inconvenient. Utility Model Content

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

[0004] According to one aspect of the present invention, an air conditioner chassis flanging mold is provided, comprising an upper mold assembly and a lower mold assembly. The upper mold assembly includes an upper ejector plate, an upper template insert, and an upper mold base, an upper clamping plate, and an upper template arranged sequentially from top to bottom. The upper ejector plate is disposed on the upper template, and the upper template insert is fixed on the upper template. The lower mold assembly includes a lower mold core, a lower ejector plate, and a lower template, a lower pad, a lower clamping plate, a lower mold base, a lower pad foot, and a lower support plate arranged sequentially from top to bottom. The lower mold core is correspondingly disposed with the upper template insert and is fixed above the lower template. The lower ejector plate is sleeved on the outside of the lower template. The lower ejector plate is provided with positioning pins, and positioning pins are provided on both adjacent sides of the lower ejector plate. The positioning pins are located on the outside of the lower mold core, and the highest point of the positioning pin is lower than the highest point of the lower mold core.

[0005] The beneficial effects of this utility model are as follows: By providing positioning pins on both sides of the lower ejector plate, the sheet material to be processed can be pressed against the positioning pins on both sides, thereby achieving positioning of both sides of the sheet material. This means that the position of the entire sheet material on the mold is defined, which is conducive to the rapid and accurate placement of the sheet material. The requirements for the operator's operating experience are greatly reduced, and the operation is convenient. At the same time, the lower ejector plate can be easily moved relative to the lower template, so that it can act on the base plate after the lower mold core is turned over, so that the lower mold core can be separated from the product, achieving rapid demolding of the product and greatly simplifying the entire mold structure.

[0006] In some embodiments, the upper mold assembly further includes a compression spring, one end of which abuts against the upper mold base, and the other end of which abuts against the upper ejector plate. Thus, by providing a compression spring, elastic force can be easily applied to the upper ejector plate, which in turn acts on the product, causing the flanged product to separate from the upper mold.

[0007] In some embodiments, the lower mold assembly further includes an ejector plate and a connecting rod. The ejector plate is located below the lower mold base. One end of the connecting rod is connected to the lower ejector plate, and the other end of the connecting rod passes through the lower clamping plate and the lower mold base before connecting to the ejector plate. Thus, force can be applied to the ejector plate and, through the connecting rod, to the lower ejector plate, causing the lower ejector plate to move upwards. The inner edge of the lower ejector plate acts on the flanged product, allowing the product to be ejected from the lower mold core, thereby completing the demolding process. Demolding is convenient and the structure is simple.

[0008] In some embodiments, the upper mold base is provided with a guide sleeve, and the lower mold base is provided with a guide post, which cooperates with the guide sleeve. Thus, the cooperation between the guide post and the guide sleeve facilitates the precise coordination between the upper and lower mold devices, ensuring the flanging quality of the product.

[0009] In some embodiments, the air conditioner chassis flanging mold also includes a hydraulic cylinder, the piston rod of which is connected to the ejector plate. Thus, by providing a hydraulic cylinder, the ejector plate can be easily moved upwards, enabling the product to be demolded from the lower mold. Attached Figure Description

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

[0016] Reference Figures 1-3An air conditioner chassis flanging mold includes an upper mold assembly 1 and a lower mold assembly 2. The upper mold assembly 1 includes an upper ejector plate 11, an upper template insert 12, and an upper mold base 13, an upper clamping plate 14, and an upper template 15 arranged from top to bottom. The upper ejector plate 11 is disposed on the upper template 15, and the upper template insert 12 is fixed on the upper template 15. The lower mold assembly 2 includes a lower mold core 21, a lower ejector plate 22, and a lower template 23, a lower pad 24, a lower clamping plate 25, a lower mold base 26, a lower pad foot 27, and a lower support plate 28 arranged from top to bottom. The lower mold core 21 is correspondingly disposed with the upper template insert 12 and is fixed above the lower template 23. The lower ejector plate 22 is sleeved on the outside of the lower template 23. The lower ejector plate 22 is provided with a positioning pin 3, and positioning pins 3 are provided on both adjacent sides of the lower ejector plate 22. The positioning pins 3 are located on the outside of the lower mold core 21, and the highest point of the positioning pin 3 is lower than the highest point of the lower mold core 21. The upper release plate 11 is fitted onto the upper template 15, and the outer wall of the upper release plate 11 is pressed against the inner wall of the upper template 15.

[0017] The upper ejector plate 11 can be T-shaped, with a T-slot formed in the upper template 15. The upper ejector plate 11 is inserted into the T-slot from one side, thus achieving a fit between the upper ejector plate 11 and the upper template 15. To facilitate the vertical movement of the upper ejector plate 11, the length of the T-slot is greater than the length of the upper ejector plate 11, allowing the upper ejector plate 11 to move vertically within the T-slot. This type of fit is a common T-shaped component and T-slot fit, and will not be elaborated further here.

[0018] In actual use, the bottom end of the positioning pin 3 is fixed to the lower mold base 26, and the other end extends upward after passing through the lower clamping plate 25 and the lower stripper plate 22. Since positioning pins 3 are provided on both adjacent sides of the lower stripper plate 22, and there can be two or three positioning pins 3 on each side, when the product needs to be flanged, the blank is pressed against the positioning pins 3 on both sides. The positioning pins 3 can quickly position both sides of the blank, thereby ensuring the consistency of blank placement each time and ensuring the flanging quality of the product.

[0019] When the air conditioner chassis flanging mold of this utility model is closed, the upper mold device 1 moves downward, and the upper ejector plate 11 contacts the blank, pressing the blank and preventing it from moving. As the upper mold device 1 continues to move downward, the upper mold insert 12 cooperates with the lower mold core 21, and the lower ejector plate 22 is pressed down. When the mold is fully closed, the upper mold insert 12 and the lower mold core 21 work together to achieve the forming and flanging of the product (e.g., Figure 4 and Figure 5 As shown in the figure, the required air conditioning chassis is obtained.

[0020] The upper mold assembly 1 also includes a compression spring 16, one end of which abuts against the upper mold base 13, and the other end of which abuts against the upper ejector plate 11. To facilitate the installation of the compression spring 16, a mounting groove is provided at the bottom end of the upper mold base 13, and one end of the compression spring 16 is fitted into the mounting groove. A through hole is provided on the upper clamping plate 14, so that the compression spring 16 passes through the through hole and abuts against the upper ejector plate 11.

[0021] When the mold is closed, the upper ejector plate 11 is pressed upward, and the upper ejector plate 11 acts on the compression spring 16, causing the compression spring 16 to be compressed. After the air conditioner chassis is flanged, during the mold opening process, the rebound force of the compression spring 16 acts on the upper ejector plate 11, pushing the upper ejector plate 11 downward, causing the upper ejector plate 11 to push the product downward and separate it from the upper mold insert 12, leaving the air conditioner chassis on the lower mold.

[0022] The lower mold device 2 also includes a punch plate 29 and a connecting rod 4. The punch plate 29 is located below the lower mold base 26. One end of the connecting rod 4 is connected to the lower ejector plate 22, and the other end of the connecting rod 4 passes through the lower clamping plate 25 and the lower mold base 26 and is connected to the punch plate 29.

[0023] The upper mold base 13 is provided with a guide sleeve 5, and the lower mold base 26 is provided with a guide post 6. The guide post 6 cooperates with the guide sleeve 5. When the mold is closed, the guide post 6 is inserted into the guide sleeve 5, which can guide the upper mold device and facilitate the accuracy of the upper and lower mold closing.

[0024] The air conditioning chassis flanging mold of this utility model also includes a hydraulic cylinder (not shown in the figure), and the piston rod of the hydraulic cylinder is connected to the ejector plate 29. The cylinder body of the hydraulic cylinder is mounted on the lower support plate 28, and the piston rod of the hydraulic cylinder extends upward and connects to the ejector plate 29. Multiple hydraulic cylinders are used to facilitate the uniformity of the force acting on the ejector plate 29.

[0025] When the mold is closed, the lower ejector plate 22 is pressed downwards by the pushing action of the upper mold plate. At this time, the piston rod of the hydraulic cylinder is pressed downwards. After the air conditioner chassis is flanged, the mold opens. When the upper mold device 1 moves upwards and separates from the lower ejector plate 22 by a certain distance, the piston rod of the hydraulic cylinder pushes upwards, pushing the ejector plate 29 upwards. The ejector plate 29 pulls the lower ejector plate 22 downwards together through the connecting rod 4. When the lower ejector plate 22 moves downwards, the inner ring of the lower ejector plate 22 can act as a scraper, smoothly ejecting the product from the lower mold and preventing the product from being stuck on the lower mold. The operator can directly remove the flanged air conditioner chassis. The structure is simple, eliminating the multiple springs structure of the lower mold in the prior art, which helps to improve the service life of the entire mold and ensures the flanged quality of the product.

[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.
