Abstract
Description
Technical Field
[0001] This application relates to the field of die-casting parts processing technology, and more specifically, to a deburring mold for die-casting parts. Background Technology
[0002] In the production of aluminum alloy die-cast parts, to meet the requirements of heat dissipation and weight reduction, various hollow structures are often designed on the side walls of the parts without affecting performance and strength. This structure is manifested as an intercalation structure in the die-casting mold. However, in the mass production process of die casting, this intercalation structure inevitably produces burrs. Traditional burr removal methods rely on manual operation, which not only increases additional costs, but the related expenses may even exceed the profits brought by the weight reduction due to the hollow design. Therefore, it is necessary to design an efficient deburring solution to reduce part costs and improve production efficiency. Summary of the Invention
[0003] The purpose of this application is to provide a deburring mold for die-cast parts, which can solve the technical problem that traditional burr removal methods rely on manual operation, which not only increases additional costs but also results in poor production efficiency.
[0004] This application provides a deburring mold for die-cast parts, including a lower template for placing the die-cast parts and an upper template disposed above the lower template. An upper mold base is fixedly disposed at the bottom of the upper template, and a punch is fixedly disposed at the bottom of the upper mold base. The punch is inclined and can be moved to insert into the side wall through hole of the die-cast parts.
[0005] The upper template has a stripper plate at its bottom, and an elastic element is provided between the upper template and the stripper plate. The stripper plate has a guide hole that matches the punch, and the punch passes through the guide hole.
[0006] The lower mold base is fixedly installed on the top of the lower mold plate, and a positioning plate is fixedly installed on the lower mold base. The die-casting part is placed on the positioning plate, and a first positioning rod is fixedly installed on the positioning plate. The first positioning rod can be inserted and engaged with the first positioning hole of the die-casting part.
[0007] The lower mold base is fixedly provided with multiple positioning blocks, which are evenly distributed around the positioning disk. A second positioning rod is fixedly provided on each positioning block, and the second positioning rod can be inserted and engaged with the second positioning hole of the die-cast part.
[0008] The lower template and the lower mold base are both provided with interconnected chip removal holes, which correspond to the side wall through holes of the die-cast part.
[0009] The upper template has a fixed limit post at its bottom, and the lower template has a limit hole that matches the limit post.
[0010] The upper template has an upper mold foot and an upper support base fixedly installed at its top, and the lower template has a lower mold foot and a lower support foot fixedly installed at its bottom.
[0011] The angle of inclination of the punch is 1.5° to 3.5°.
[0012] The beneficial effects of this utility model are:
[0013] This utility model provides a deburring mold for die-cast parts. In use, the lower mold plate is installed on the top of the equipment platform, and the upper mold plate is installed on the bottom of the hydraulic equipment. First, the die-cast part is placed on the top of the lower mold plate. Then, the upper mold plate is moved down by the external hydraulic equipment. The upper mold base moves down with the upper mold plate, and the punch moves down with the upper mold base until the punch inserts into the side wall through hole of the die-cast part and scrapes off the burrs. This mold, by setting an inclined punch, forms a dynamic shearing action with the side wall through hole of the die-cast part. When the punch is inserted at an incline, the lateral component force generated by the angle scrapes the root of the burr, while the vertical component force completes the material separation. Compared with conventional vertical punches, the inclined punch can more effectively scrape off the burrs penetrating the side wall through hole of the die-cast part, avoid residue, reduce production time, improve production efficiency, and eliminate the need for additional labor, thus reducing production costs. Moreover, it does not produce processing omissions and improves the quality yield. Attached Figure Description

[0031] like Figures 1 to 6 As shown, this application provides a deburring mold for die-cast parts, including a lower template 2 for placing the die-cast part 1 and an upper template 3 disposed above the lower template 2. An upper mold base 31 is fixedly disposed at the bottom of the upper template 3, and a punch 32 is fixedly disposed at the bottom of the upper mold base 31. The punch 32 is inclined and can be moved to insert into the side wall through hole 11 of the die-cast part 1.
[0032] In use, the lower template 2 is installed on the top of the equipment platform and the upper template 3 is installed on the bottom of the hydraulic equipment. First, the die-casting part 1 is placed on the top of the lower template 2. Then, the upper template 3 is moved down by the external hydraulic equipment. The upper mold base 31 moves down with the upper template 3, and the punch 32 moves down with the upper mold base 31 until the punch 32 is inserted into the side wall through hole 11 of the die-casting part 1 and scrapes off the burrs.
[0033] The mold uses an inclined punch 32 to create a dynamic shearing action with the side wall through hole 11 of the die-cast part 1. When the punch 32 is inserted at an incline, the lateral force generated by the angle scrapes the root of the burr, while the vertical force completes the material separation. Compared with the conventional vertical punch 32, the inclined punch 32 can more effectively scrape the insertion burrs of the side wall through hole 11 of the die-cast part 1, avoid residue, reduce production time, improve production efficiency, and eliminate the need for additional manpower, thus reducing production costs. Moreover, it does not produce processing omissions and improves the quality yield.
[0034] like Figure 1 and 2 As shown, in this embodiment, a stripper plate 33 is provided at the bottom of the upper template 3, and an elastic element is provided between the upper template 3 and the stripper plate 33. A guide hole 34 adapted to the punch 32 is provided on the stripper plate 33, and the punch 32 passes through the guide hole 34.
[0035] During use, the upper mold plate 3 is moved downward by an external hydraulic device. The upper mold base 31 moves downward with the upper mold plate 3, and the punch 32 and stripper plate 33 move downward with the upper mold base 31. The stripper plate 33 presses on the die-cast part 1. Then the punch 32 continues to move downward until it inserts into the side wall through hole 11 of the die-cast part 1 and removes the burrs. After deburring, the upper mold plate 3 is moved upward and reset by an external hydraulic device. The upper mold base 31 moves upward with the upper mold plate 3, and the punch 32 moves upward with the upper mold base 31. Under the elastic force of the elastic element, the stripper plate 33 remains pressed on the die-cast part 1. After the punch 32 leaves the die-cast part 1, the stripper plate 33 also leaves the die-cast part 1. The stripper plate 33 can effectively prevent the die-cast part 1 from being moved upward by the punch 32 during its ascent. The guide hole 34 on the stripper plate 33 can ensure that the punch 32 moves downward at the correct angle, improving the accuracy of deburring.
[0036] like Figures 3 to 6 As shown, in this embodiment, a lower mold base 21 is fixedly provided on the top of the lower mold plate 2, and a positioning plate 22 is fixedly provided on the lower mold base 21. The die-casting part 1 is placed on the positioning plate 22, and a first positioning rod 23 is fixedly provided on the positioning plate 22. The first positioning rod 23 can be inserted and cooperated with the first positioning hole 12 of the die-casting part 1.
[0037] In use, the die-cast part 1 is placed on the positioning plate 22, and the first positioning rod 23 is inserted into the first positioning hole 12 of the die-cast part 1 to achieve the positioning and installation of the die-cast part 1, ensuring the accurate positioning of the die-cast part 1 in the mold, further improving the accuracy of deburring, and enhancing the stability of the die-cast part 1 in the deburring process.
[0038] like Figures 3 to 6As shown, in this embodiment, a plurality of positioning blocks 24 are fixedly arranged on the lower mold base 21. The plurality of positioning blocks 24 are evenly distributed around the positioning disk 22. A second positioning rod 25 is fixedly arranged on the positioning block 24. The second positioning rod 25 can be inserted and engaged with the second positioning hole 13 of the die-casting part 1.
[0039] In use, the die-cast part 1 is placed on the positioning plate 22, and the first positioning rod 23 is inserted into the first positioning hole 12 of the die-cast part 1, and the second positioning rod 25 is inserted into the second positioning hole 13 of the die-cast part 1, so as to realize the positioning and installation of the die-cast part 1, further fix the position of the die-cast part 1, ensure the accurate positioning of the die-cast part 1 in the mold, further improve the accuracy of deburring, and enhance the stability of the die-cast part 1 in the deburring process.
[0040] like Figure 4 and 5 As shown, in this embodiment, both the lower template 2 and the lower mold base 21 are provided with interconnected chip removal holes 26, which correspond to the side wall through holes 11 of the die-casting part 1. During use, the removed burrs are discharged from the mold through the chip removal holes 26, thus avoiding the accumulation of burrs in the mold.
[0041] like Figure 1 and 2 As shown, in this embodiment, a limiting post 35 is fixedly provided at the bottom of the upper template 3, and a limiting hole 27 adapted to the limiting post 35 is provided on the lower template 2. When the mold is closed, the limiting post 35 is inserted into the limiting hole 27 to control the relative position of the upper template 3 and the lower template 2 so that it does not shift. The design of the limiting post 35 and the limiting hole 27 ensures the accuracy of the mold when it is closed and improves the quality of deburring.
[0042] like Figures 1 to 5 As shown, in this embodiment, the top of the upper template 3 is fixedly provided with an upper mold foot 36 and an upper support seat 37, and the bottom of the lower template 2 is fixedly provided with a lower mold foot 28 and a lower support foot 29. The top of the upper template 3 is positioned and installed at the bottom of the hydraulic equipment through the upper mold foot 36 and the upper support seat 37, and the bottom of the lower template 2 is positioned and installed at the top of the equipment platform through the lower mold foot 28 and the lower support foot 29. The upper mold foot 36, the upper support seat 37, the lower mold foot 28 and the lower support foot 29 provide stable support and fixation for the mold.
[0043] In this embodiment, the tilt angle of the punch 32 is 1.5° to 3.5°; a punch 32 with a suitable tilt angle can be selected according to actual usage requirements to ensure that the punch 32 can effectively scrape the burrs in the through hole 11 on the side wall of the die-cast part 1.
[0044] Working principle: When using the deburring mold for die-cast parts provided in this application, the lower template 2 is installed on the top of the equipment platform, and the upper template 3 is installed on the bottom of the hydraulic equipment. First, the die-cast part 1 is placed on the positioning plate 22, and the first positioning rod 23 is inserted into the first positioning hole 12 of the die-cast part 1, and the second positioning rod 25 is inserted into the second positioning hole 13 of the die-cast part 1. Then, the upper template 3 is moved down by the external hydraulic equipment, and the upper mold base 31 moves down with the upper template 3. The punch 32 and the stripper plate 33 move down with the upper mold base 31. The stripper plate 33 presses onto the die-cast part 1, and then the punch 32 continues to move downward until it inserts into the side wall through hole 11 of the die-cast part 1 and scrapes off the burrs. The removed burrs are discharged from the mold through the chip removal hole 26. After deburring, the upper template 3 is moved upward and reset by the external hydraulic equipment. The upper mold base 31 moves upward with the upper template 3, and the punch 32 moves upward with the upper mold base 31. Under the elastic force of the elastic element, the stripper plate 33 remains pressed on the die-cast part 1. After the punch 32 leaves the die-cast part 1, the stripper plate 33 also leaves the die-cast part 1.
[0045] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
