Description

Technical Field

[0001] This utility model belongs to the field of cold stamping casting molds. Specifically, this utility model relates to a material feeding mechanism for cold stamping casting molds. Background Technology

[0002] The development cost of automotive parts molds accounts for about 20% of the total investment in vehicle development. While reducing costs and increasing efficiency and ensuring product quality, molds can be developed using a two-part mold process. During the stamping and trimming of body sheet metal parts, stamping waste is generated. The waste is easy to accumulate in the mold, which leads to poor material discharge during production. This not only affects production efficiency but also wastes energy and labor costs.

[0003] Chinese patent CN217700989U disclosed a stamping die for an automotive seat side panel on November 1, 2022, comprising: a base, a first lower die, a second lower die, a top plate, an upper die, a drive mechanism, and a fixing plate; two fixing plates are provided on the upper surface of the base, and the first lower die and the second lower die are respectively connected to the two fixing plates through the drive mechanism; a top plate is provided above the base, and an upper die base is provided below the top plate; the upper die is provided on the lower surface of the upper die base, but the die lacks a material discharge mechanism, thus failing to solve the material discharge problem. Utility Model Content

[0004] The present invention aims to provide a material discharge mechanism for cold stamping casting molds with good material discharge effect.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cold stamping casting mold discharge mechanism includes a first cylinder mounting base and a second cylinder mounting base. A first cylinder is mounted on the first cylinder mounting base, and a second cylinder is mounted on the second cylinder mounting base. The casting mold includes a lower mold body. Both the first cylinder mounting base and the second cylinder mounting base are mounted on the lower mold body. The first cylinder mounting base is located on one side of the second cylinder mounting base. A scrap slide is located below the first cylinder mounting base and the second cylinder mounting base. A first pull rod is connected to the output end of the first cylinder, and a second pull rod is connected to the output end of the second cylinder.

[0007] The first pull rod includes a first connecting plate, a first push plate, and a first trapezoidal frame. The first connecting plate is connected to the output end of the first cylinder. One end of the first push plate is connected to the first connecting plate, and the other end of the first push plate is connected to the first trapezoidal frame. The second pull rod includes a second connecting plate, a second push plate, and a second trapezoidal frame. The second connecting plate is connected to the output end of the second cylinder. One end of the second push plate is connected to the second connecting plate, and the other end of the second push plate is connected to the second trapezoidal frame.

[0008] The bottom of the first cylinder mounting base is provided with a first limiting through hole, and a first guide rod is provided in the first limiting through hole. The first guide rod and one end of the first connecting plate are connected by a first stop nut. The bottom of the second cylinder mounting base is provided with a second limiting through hole, and a second guide rod is provided in the second limiting through hole. One end of the second guide rod and one end of the second connecting plate are connected by a second stop nut.

[0009] The first cylinder has a first air pipe connected to its air port, and the second cylinder has a second air pipe connected to its air port.

[0010] The first air pipe is provided with a first air distribution block, the first air distribution block is provided with a first air passage connector, the first air passage connector is provided with a first air passage connector fixing seat, and the first air passage connector fixing seat is located on one side of the lower mold body; the second air pipe is provided with a second air distribution block, the second air distribution block is provided with a second air passage connector, the second air passage connector is provided with a second air passage connector fixing seat, and the second air passage connector fixing seat is located on the other side of the lower mold body.

[0011] The lower mold body has weight-reducing holes on both sides, and the first air pipe and the second air pipe are respectively installed in the weight-reducing holes on both sides.

[0012] The first guide rod and the first limiting through hole are in clearance fit, and the second guide rod and the second limiting through hole are in clearance fit.

[0013] The waste material slide plate is inclined.

[0014] Both the first cylinder mounting base and the second cylinder mounting base are fixed to the middle of the lower mold body by positioning pins and bolts.

[0015] The first air distribution block and the first air passage connector, as well as the second air distribution block and the second air passage connector, are all provided in multiple sets.

[0016] The technical advantages of this invention are as follows: By setting a first cylinder to drive a first pull rod and a second cylinder to drive a second pull rod, the cylinders drive the corresponding pull rods to extend and retract, thereby pulling the stamping waste generated during the stamping and trimming of the body sheet metal parts into the waste slide for discharge. This allows for rapid discharge of waste from the mold, improving the problem of poor discharge, preventing the accumulation of stamping waste, reducing the labor required for manual cleaning of stamping waste and the number of downtimes needed for cleaning, and improving production efficiency. It can be effectively applied to one-mold two-part processes, reducing mold development costs. Furthermore, it has a simple structure, low manufacturing cost, and strong practicality. The air distribution block reduces the number of external pipes, integrates them, is aesthetically pleasing and reliable, and occupies a small area. The air pipes are set inside the weight-reducing holes of the lower mold body to avoid interference during stamping and to avoid re-opening the mold for air pipe routing, thus reducing mold opening costs.

[0026] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this utility model, and to facilitate its implementation.

[0027] like Figure 1As shown, a cold stamping casting mold discharge mechanism includes a first cylinder mounting base 1 and a second cylinder mounting base 2. A first cylinder 3 is mounted on the first cylinder mounting base 1, and a second cylinder 4 is mounted on the second cylinder mounting base 2. The casting mold includes a lower mold body 5. Both the first cylinder mounting base 1 and the second cylinder mounting base 2 are mounted on the lower mold body 5. The first cylinder mounting base 1 is located on one side of the second cylinder mounting base 2. A scrap slide plate 6 is located below the first cylinder mounting base 1 and the second cylinder mounting base 2. A first pull rod 7 is connected to the output end of the first cylinder 3, and a second pull rod 8 is connected to the output end of the second cylinder 4. By having the first cylinder 3 drive the first pull rod 7, and the second cylinder 4 drive the second pull rod 8, the stamping scrap can be quickly discharged from the mold during the trimming process, improving the problem of poor discharge, avoiding the accumulation of stamping scrap, reducing the labor required for manual cleaning of stamping scrap, and reducing the number of machine stops needed for cleaning stamping scrap, thereby improving production efficiency. By setting two cylinders with opposite piston movement directions in the middle of the lower mold body 5 of the casting mold, it can be effectively applied to the two-piece mold process, reducing mold development costs. The structure is simple, manufacturing cost is low, and practicality is strong. The first cylinder 3 and the second cylinder 4 have the same structure, both being ordinary cylinders with built-in magnetic rings. The first pull rod 7 and the second pull rod 8 are composite pull rods. Compared with ordinary pull rods, the composite pull rods enhance the gripping force on the main runner waste through a combined structure, preventing solidified material from adhering to the fixed mold side during mold opening, resulting in better performance.

[0028] like Figure 2 , Figure 4 and Figure 5 As shown, the first pull rod 7 includes a first connecting plate 9, a first push plate 10, and a first trapezoidal frame 11. The first connecting plate 9 is connected to the output end of the first cylinder 3. One end of the first push plate 10 is connected to the first connecting plate 9, and the other end of the first push plate 10 is connected to the first trapezoidal frame 11. The second pull rod 8 includes a second connecting plate 12, a second push plate 13, and a second trapezoidal frame 14. The second connecting plate 12 is connected to the output end of the second cylinder 4. One end of the second push plate 13 is connected to the second connecting plate 12, and the other end of the second push plate 13 is connected to the second trapezoidal frame 14. The first trapezoidal frame 11 and the second trapezoidal frame 14 are located on both sides of the lower die body 5. The waste material from the stamping sheet metal parts on both sides during the trimming process is cut off and inserted into the trapezoidal frames on both sides. At this time, the first cylinder 3 drives the first connecting plate 9 and the first push plate 10, and the second cylinder 4 drives the second connecting plate 12 and the second push plate 13 to pull the stamping waste material into the waste slide plate 6 for discharge. After the discharge is completed, the two cylinders push the pull rod back to its original position through the air pipe, and then repeat the next discharge.

[0029] like Figure 3 , Figure 6 and Figure 7As shown, the bottom of the first cylinder mounting base 1 is provided with a first limiting through hole 15, and a first guide rod 16 is provided in the first limiting through hole 15. The first guide rod 16 and one end of the first connecting plate 9 are connected by a first stop nut 17. The bottom of the second cylinder mounting base 2 is provided with a second limiting through hole 18, and a second guide rod 19 is provided in the second limiting through hole 18. The second guide rod 19 and one end of the second connecting plate 12 are connected by a second stop nut 20. One end of the first guide rod 16 is connected to the first connecting plate 9 via the first stop nut 17, allowing for adjustment of the length of the first guide rod 16. The first cylinder mounting base 1 is provided with a first limiting through hole 15, and the other end of the first guide rod 16 is movably disposed within the first limiting through hole 15 to limit and guide the first pulling rod 7, thereby effectively ensuring the accuracy of the extension and retraction of the first pulling rod 7 and preventing jamming due to deviation. One end of the second guide rod 19 is connected to the second connecting plate 12 via the second stop nut 20, allowing for adjustment of the length of the second guide rod 19. The second cylinder mounting base 2 is provided with a second limiting through hole 18, and the other end of the second guide rod 19 is movably disposed within the second limiting through hole 18 to limit and guide the second pulling rod 8, thereby effectively ensuring the accuracy of the extension and retraction of the second pulling rod 8 and preventing jamming due to deviation.

[0030] The first cylinder 3 is connected to a first air pipe 21, and the second cylinder 4 is connected to a second air pipe 22. The first cylinder 3 is connected to a first air intake pipe 21, and the second cylinder 4 is connected to a second air intake pipe 22, which are used to guide air into the cylinder.

[0031] The first air pipe 21 is equipped with a first air distribution block 23, the first air distribution block 23 is equipped with a first air passage connector 24, and the first air passage connector 24 is equipped with a first air passage connector fixing seat 25, which is located on one side of the lower mold body 5. The second air pipe 22 is equipped with a second air distribution block 26, the second air distribution block 26 is equipped with a second air passage connector 27, and the second air passage connector 27 is equipped with a second air passage connector fixing seat 28, which is located on the other side of the lower mold body 5. The first air passage connector fixing seat 25 and the second air passage connector fixing seat 28 are respectively located on both sides of the lower mold body 5. The first air passage connector 24 is installed on the first air passage connector fixing seat 25, and one end of the first air pipe 21 is connected to the first air passage connector 24 through the first air distribution block 23. The second air passage connector 27 is installed on the second air passage connector fixing seat 28, and one end of the second air pipe 22 is connected to the second air distribution block 26 and the second air passage connector 27.

[0032] Weight reduction holes 29 are provided on both sides of the lower mold body 5, and the first air pipe 21 and the second air pipe 22 are respectively installed in the weight reduction holes 29 on both sides. The first air pipe 21 and the second air pipe 22 are respectively installed in the weight reduction holes 29 on both sides of the lower mold body 5 to avoid interference during the stamping process and to avoid re-opening the mold to arrange the air pipes, thereby reducing the mold opening cost.

[0033] The first guide rod 16 is clearance-fitted with the first limiting through hole 15, and the second guide rod 19 is clearance-fitted with the second limiting through hole 18. The clearance fit between the guide rod and the limiting through hole allows the guide rod to be movably disposed within the limiting through hole.

[0034] The waste slide plate 6 is an inclined surface. The inclined surface in the middle of the lower mold body 5 facilitates waste discharge.

[0035] Both the first cylinder mounting base 1 and the second cylinder mounting base 2 are fixed to the middle of the lower mold body 5 by positioning pins and bolts. The extension direction of the piston of the first cylinder 3 is opposite to that of the piston of the second cylinder 4. By setting two cylinders with opposite piston movement directions, the waste generated by the trimming process of the stamped sheet metal parts on the left and right sides can be discharged simultaneously.

[0036] Multiple sets of the first gas distribution block 23 and the first gas path connector 24, as well as the second gas distribution block 26 and the second gas path connector 27, are all provided. This multiple setup allows for efficient gas source distribution and reliable connection.

[0037] The working principle of this utility model:

[0038] The first cylinder mounting base 1 and the second cylinder mounting base 2 are both located in the middle of the lower die body 5. The first cylinder 3 is mounted on the first cylinder mounting base 1, and the second cylinder 4 is mounted on the second cylinder mounting base 2. The lower die body 5 is a two-piece die, with the stamped sheet metal parts placed on both sides of the lower die body 5. The two cylinders and the cylinder mounting bases are located in the middle of the two stamped sheet metal parts. The two cylinders are arranged with opposite piston directions. The output end of the first cylinder 3 is connected to the first pull rod 7, and the output end of the second cylinder 4 is connected to the second pull rod 8. During the trimming process, the stamping waste can be quickly discharged from the die, improving the problem of poor material discharge, avoiding the accumulation of stamping waste, reducing the labor required for manual cleaning of stamping waste and the number of machine stops required for cleaning stamping waste, and improving production efficiency. The first trapezoidal frame 11 and the second trapezoidal frame 14 are located on both sides of the lower mold body 5. The waste material from the stamped sheet metal parts on both sides during the trimming process is cut off and inserted into the trapezoidal frames on both sides. At this time, the first cylinder 3 drives the first connecting plate 9 and the first push plate 10, and the second cylinder 4 drives the second connecting plate 12 and the second push plate 13 to pull the stamped waste material into the waste slide plate 6 for discharge. After the discharge is completed, the two cylinders push the pull rod back to its original position through the air pipe, and then repeat the next discharge. The inclined scrap slide plate 6 is more conducive to the discharge of stamping scrap from the lower die body 5; the bottom of the first cylinder fixing seat 1 is provided with a first limiting through hole 15, and one end of the first guide rod 16 is connected to the first connecting plate 9 through the first stop nut 17, so that the length of the first guide rod 16 can be adjusted; the first cylinder fixing seat 1 is provided with a first limiting through hole 15, and the first guide rod 16 is provided in the first limiting through hole 15. The other end of the first guide rod 16 is movably provided in the first limiting through hole 15 to limit and guide the first pull rod 7, thereby effectively ensuring the telescopic movement accuracy of the first pull rod 7. Similarly, the second cylinder fixing seat 2 is also provided with a second guide rod 19, which is located in the second limiting through hole 18 to limit and guide the second pull rod 8, so as to avoid the problem of jamming caused by deviation.

Obviously, the specific implementation of the present invention is not limited to the above-described manner.
