Description

Technical Field

[0001] This utility model belongs to the field of mold technology, and more specifically, it relates to a forging mold. Background Technology

[0002] Forging dies are an indispensable core forming equipment in the field of machinery manufacturing. They are widely used in the production and processing of various metal products such as automotive parts, aerospace components, and engineering machinery parts. The working principle of forging dies is to use the high pressure applied by forging equipment to cause high-temperature metal billets to undergo plastic deformation inside the pre-set cavity of the die, and finally form a workpiece that meets the design specifications, dimensional accuracy and mechanical performance requirements. It is a key means to realize the efficient utilization of metal materials and the mass production of components.

[0003] However, traditional forging dies often have obvious limitations. During the reciprocating process of mold closing and opening, some forging dies are easily affected by metal debris or uneven force, resulting in relative displacement, which leads to positioning deviation and makes the workpiece shape not meet expectations. There is an urgent need for a forging die with improved positioning capability. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a forging die to solve the technical problem that traditional forging dies are prone to positioning deviations in the prior art.

[0005] The purpose and effect of this forging die are achieved by the following specific technical means:

[0006] A forging die includes an upper die and a lower die. The upper die has a positioning component at its bottom and a protective component at its top. The positioning component includes four sets of upper limit grooves. The upper die has four sets of upper limit grooves at its bottom and the lower die has four sets of lower limit posts at its top. The protective component includes four sets of first rubber pads. The four sets of upper limit grooves each have four sets of first rubber pads, and the four sets of lower limit posts each have four sets of second rubber pads at their tops.

[0007] According to a preferred embodiment, the positioning component further includes four sets of guide rods, the top of the upper mold is provided with four sets of guide rods, the upper mold is provided with four sets of mounting holes, and the top of the upper mold is provided with a fixing bracket.

[0008] According to a preferred embodiment, the top of the lower mold is provided with four sets of threaded holes, and one end of each of the four sets of guide rods passes through the four sets of mounting holes and is inserted into the four sets of threaded holes.

[0009] According to a preferred embodiment, the protective assembly further includes four sets of first dust covers, and the top of the upper mold is provided with four sets of the first dust covers, the inner walls of the four sets of first dust covers respectively contacting the outer walls of the four sets of guide rods.

[0010] According to a preferred embodiment, the top of the upper mold is provided with four sets of first mounting slots, the bottom of the four sets of first dust covers is provided with four sets of first protective covers, and the top of the lower mold is provided with four sets of protective films.

[0011] According to a preferred embodiment, one end of each of the four sets of first dust covers is inserted into one of the four sets of first mounting slots, and the bottom of the upper mold is provided with four sets of second mounting slots.

[0012] According to a preferred embodiment, the bottom of the upper mold is provided with four sets of second dustproof sleeves, and one end of each of the four sets of second dustproof sleeves passes through the four sets of second mounting slots.

[0013] According to a preferred embodiment, four sets of second protective sleeves are respectively provided at the bottom of the four sets of second dust covers, and the inner walls of the four sets of second protective sleeves respectively contact the four sets of guide rods.

[0014] According to a preferred embodiment, the upper mold has an upper mold cavity at its bottom, the lower mold has a lower mold cavity at its top, and material retention slots are provided on both sides of the lower mold cavity.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Through the setting of the positioning components, the bottom of the upper mold has four sets of upper limit grooves, the top of the lower mold has four sets of lower limit posts, the top of the upper mold has four sets of guide rods, the upper mold has four sets of mounting holes, and the top of the lower mold has four sets of threaded holes. The four sets of guide rods pass through the four sets of mounting holes of the upper mold, and one end is threadedly connected to the four sets of threaded holes on the top of the lower mold. The top of the upper mold has a fixed bracket. The guide rods and the mounting holes form a sliding fit, which can guide the upper mold to move smoothly along a fixed trajectory to the lower mold and avoid deviation during the movement. The threaded holes can limit the guide rods and prevent the guide rods from shaking during the reciprocating motion of mold closing and opening, thereby causing the upper mold to deviate from the preset trajectory. As the guide rods guide the upper mold to gradually approach the lower mold, the lower limit posts are simultaneously and gradually embedded into the upper limit grooves, which can limit the relative displacement of the upper mold and the lower mold in the horizontal direction and avoid misalignment when the mold is closed. The fixed bracket can constrain the parallelism of the four sets of guide rods and prevent the upper mold from jamming and positioning deviation caused by the skew of a single guide rod. This solves the problem of easy deviation in the positioning of traditional forging molds.

[0017] 2. Through the setting of protective components, four sets of first rubber pads are respectively set in the four sets of upper limit grooves, and four sets of second rubber pads are respectively set on the top of the four sets of lower limit posts. During the mold closing process, when the lower limit posts are gradually embedded into the upper limit grooves, the first rubber pads and the second rubber pads come into contact first, which can reduce the rigid contact between the upper limit grooves and the lower limit posts, avoid wear or deformation caused by direct collision, and reduce the maintenance needs caused by component damage. Four sets of first dustproof sleeves are set on the top of the upper mold, and four sets of second dustproof sleeves are set on the bottom of the upper mold. These can prevent metal chips, dust and other foreign objects generated during the forging process from entering the mounting hole, preventing foreign objects from affecting the fit between the guide rod and the mounting hole, and avoiding jamming or wear. Four sets of protective films are set on the top of the lower mold, which can prevent foreign objects from entering the threaded hole, preventing the thread from having fit problems due to foreign object blockage or corrosion, reducing the cleaning and repair work of the threaded hole, and solving the problem of frequent maintenance required by traditional forging dies.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] Example 1

[0026] As attached Figure 1 To be continued Figure 6As shown: This utility model provides a forging die, including an upper die 11 and a lower die 12. A positioning component is provided at the bottom of the upper die 11, and a protective component is provided at the top of the lower die 12. The positioning component includes four sets of upper limit grooves 13. The upper die 11 has four sets of upper limit grooves 13 at its bottom, and the lower die 12 has four sets of lower limit posts 14 at its top. When the die is closed, the four sets of lower limit posts 14 are respectively embedded in the four sets of upper limit grooves 13, restricting the relative horizontal displacement of the upper die 11 and the lower die 12, preventing positioning deviations, and simultaneously constraining the die closing depth to avoid... Misalignment between the upper mold 11 and the lower mold 12 affects the forming effect of the workpiece. The protective component includes four sets of first rubber pads 25. Four sets of first rubber pads 25 are respectively installed in the four sets of upper limit grooves 13. Four sets of second rubber pads 28 are respectively installed on the top of the four sets of lower limit posts 14. As the lower limit post 14 is gradually inserted into the upper limit groove 13, the second rubber pads 28 first contact with the first rubber pads 25 and generate compression, which can reduce the rigid contact between the upper limit groove 13 and the lower limit post 14, avoid wear or chipping caused by direct collision, and ensure the long-term continuous operation of the device.

[0027] Please refer to, for example Figure 1 , Figure 2 and Figure 5 As shown, the positioning assembly also includes four sets of guide rods 21. The upper mold 11 has four sets of guide rods 21 on its top and four sets of mounting holes 19. The guide rods 21 and mounting holes 19 are sized to fit together in a sliding fit. The lower mold 12 has four sets of threaded holes 18 on its top. The four sets of guide rods 21 pass through the four sets of mounting holes 19 of the upper mold 11, and one end is threadedly connected to the four sets of threaded holes 18 on the top of the lower mold 12. With the cooperation of the guide rods 21 and mounting holes 19, the upper mold 11 is guided to move along a fixed trajectory towards the lower mold 12. The threaded holes 18 can limit the movement of the guide rods 21, preventing wobbling during the reciprocating motion of mold closing and opening, and avoiding deviation of the upper mold 11 from the preset trajectory. The upper mold 11 has a fixed bracket 32 ​​on its top. The inner walls of the four rings on the fixed bracket 32 ​​contact the outer walls of the four sets of guide rods 21, constraining the parallelism of the four sets of guide rods 21 and preventing the upper mold 11 from jamming or shifting due to the skew of a single guide rod 21.

[0028] Please refer to, for example Figure 1 and Figure 2As shown, the protective assembly also includes four sets of first dust covers 24. The top of the upper mold 11 is provided with four sets of first dust covers 24, which can block metal shavings, dust and other foreign objects generated during the forging process. The top of the upper mold 11 is provided with four sets of first mounting grooves 26, which are used to place the first dust covers 24 so that the first dust covers 24 fit against the top of the upper mold 11. The bottom of the four sets of first dust covers 24 is provided with four sets of first protective covers 23 to prevent foreign objects from entering the mounting hole 19. The top of the lower mold 12 is provided with four sets of protective films 17, which cover the threaded hole 18 and can block foreign objects from entering the interior, preventing the threaded hole 18 from having abnormal fit due to blockage or corrosion.

[0029] Please refer to, for example Figure 2 and Figure 4 As shown, the bottom of the upper mold 11 is provided with four sets of second mounting slots 27, and the bottom of the upper mold 11 is provided with four sets of second dust covers 31. One end of each of the four sets of second dust covers 31 passes through the four sets of second mounting slots 27. The second mounting slots 27 can limit the second dust covers 31, preventing the second dust covers 31 from shifting or falling off due to vibration during the forging process, and ensuring the stability of the protective position. The bottom of each of the four sets of second dust covers 31 is provided with four sets of second protective covers 29. The second dust covers 31 and the second protective covers 29 form a double-layer protective structure, which can prevent metal chips, dust and other foreign objects generated during forging from entering the mold.

[0030] Please refer to, for example Figure 3 and Figure 4 As shown, the upper mold 11 has an upper mold cavity 15 at its bottom, and the lower mold 12 has a lower mold cavity 16 at its top. When the molds are closed, the upper mold cavity 15 and the lower mold cavity 16 enclose each other to form a complete forming space. The high-temperature metal billet undergoes plastic deformation under pressure in this space, eventually forming a workpiece that meets the shape requirements. Material retention grooves 22 are provided on both sides of the lower mold cavity 16. The material retention grooves 22 can increase the friction between the workpiece and the lower mold 12, and prevent the workpiece from sticking to the inner wall of the upper mold cavity 15 due to adsorption force, ensuring that the workpiece remains stably in the lower mold cavity 16 when the mold is opened.
