Description

Technical Field

[0001] This utility model relates to the field of metal parts manufacturing technology, specifically to a high-efficiency and precise deburring structure for hardware molds. Background Technology

[0002] During the production and processing of automotive parts, metal burrs often appear on the surface of the parts due to the need for machining. Deburring of metal parts is a crucial step in metal processing because burrs not only affect the appearance of the product but may also affect its performance and safety. Traditional deburring methods include manual deburring and chemical deburring. Manual deburring involves direct contact between workers and burrs, posing a risk of workplace injury and resulting in low efficiency. Furthermore, chemical deburring requires the use of chemical agents, which can easily cause pollution. To address this issue, we propose a highly efficient and precise hardware mold deburring structure. By closing the lower mold assembly and the upper mold assembly, the burrs in the grooves on the metal parts are stamped, which can quickly and effectively remove burrs. Utility Model Content

Detailed Implementation

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Please see Figure 1-7 This utility model provides a high-efficiency and precise deburring structure for hardware molds: a high-efficiency and precise deburring structure for hardware molds includes a guide component 4, a lower mold component 1, a metal part 2, and an upper mold component 3. Specifically, the metal part 2 is placed on the lower mold component 1, and the burrs on the through groove of the metal part 2 are punched by the mold closing of the lower mold component 1 and the upper mold component 3, which can quickly and effectively remove burrs. Compared with traditional manual deburring or chemical deburring methods, this structure reduces the direct contact between workers and burrs, reduces the risk of workplace injuries, improves production efficiency, and eliminates the need for chemical agents, thus reducing environmental pollution.

[0042] The lower die assembly 1 and the upper die assembly 3 are fixed to the guide assembly 4 by bolts. The lower die assembly 1 and the upper die assembly 3 can be replaced according to the structure and size of the metal parts 2, so as to meet the deburring requirements of different workpieces.

[0043] When the upper die assembly 3 moves downward to close with the lower die assembly 1, the guide assembly 4 can achieve precise alignment between the lower die assembly 1 and the upper die assembly 3, which can reduce errors in the stamping process.

[0044] The lower die assembly 1 includes a lower die base 11, a material groove 12, a punch 14, a punch 2 15, a limit rod 13, and a nitrogen spring 16. Specifically, the two sets of punches 14, the multiple sets of punches 2 15, and the material groove 12 are all provided with bevels. During the stamping process, the bevels and metal parts 2 are used to achieve the effects of deburring and chamfering.

[0045] Metal part 2 is placed on lower mold assembly 1, and two sets of punches 14 pass through the upper through slot of metal part 2. Then, the upper part of multiple sets of nitrogen springs 16 contacts metal part 2. After upper mold assembly 3 and lower mold assembly 1 are closed, metal part 2 enters material groove 12. The two sets of punches 14 and multiple sets of punches 15 are used to perform deburring operation, and the beveled edge is used to perform chamfering operation on metal part 2. After upper mold assembly 3 and lower mold assembly 1 are opened, multiple sets of nitrogen springs 16 extend and push metal part 2 out of material groove 12 to achieve automatic ejection, making it easy to remove metal part 2.

[0046] The upper mold assembly 3 includes an upper mold base 31, a pressure plate 32, a nitrogen spring 33, a limiting groove 34, and a slot 35. Specifically, the positions of multiple sets of limiting grooves 34 and multiple sets of limiting rods 13 are corresponding, and the positions of two sets of slots 35 and two sets of punches 14 are corresponding. Thus, when the upper mold assembly 3 and the lower mold assembly 1 are closed, the upper parts of the multiple sets of limiting rods 13 and the two sets of punches 14 respectively enter the interior of the multiple sets of limiting grooves 34 and the two sets of slots 35, thereby aligning and guiding the movement of the upper mold assembly 3.

[0047] The guide assembly 4 includes a base plate 41, a top plate 42, guide pillars 43, and guide sleeves 44. Specifically, when the top plate 42 moves downward, it can drive the upper die base 31 to move downward. By sliding multiple sets of guide pillars 43 inside multiple sets of guide sleeves 44, the movement of the upper die assembly 3 can be guided and aligned, which can reduce errors in the stamping process.

[0048] The high-efficiency and precise deburring structure for metal molds works as follows: First, the metal part 2 is placed on the lower mold assembly 1, and two sets of punches 14 pass through the upper slot of the metal part 2. Then, the upper parts of multiple sets of nitrogen springs 16 contact the metal part 2. When the external power device drives the top plate 42 and the upper mold assembly 3 to move downward, multiple sets of guide pillars 43 slide inside multiple sets of guide sleeves 44, thereby guiding and aligning the movement of the upper mold assembly 3. After the upper mold assembly 3 and the lower mold assembly 1 are closed, the metal part 2 enters the material groove 12 and is deburred by the two sets of punches 14 and multiple sets of punches 15. The metal part 2 is also chamfered by the bevel. After the stamping is completed, the external power device drives the top plate 42 and the upper mold assembly 3 to move upward, and the multiple sets of nitrogen springs 16 extend to push the metal part 2 out of the material groove 12.
