Description

Technical Field

[0001] The invention belongs to the technical field of stamping devices, in particular to a die stamping device which is convenient for demoulding. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. Mold stamping refers to a processing method that applies pressure to the workpiece at room temperature to separate or plastically deform the material, thereby obtaining a workpiece of the desired shape and size.

[0003] The patent with announcement number CN218926034U discloses a stamping device, which relates to the technical field of stamping devices, including a base, a stamping table fixedly installed on the top of the base, a support frame fixedly connected to the top of the stamping table, and a power output device fixedly installed on the top of the support frame. The patent is arranged by the coordination between the mold shell, the movable plate, the second cylinder and the second piston rod. When the workpiece is stamped, the user can start the second cylinder, and the second cylinder drives the second piston rod to extend and push the movable plate located inside the mold shell to move up, thereby ejecting the stamped workpiece in the inner cavity of the mold shell, and avoiding the problem that the existing stamping device is hard squeezed during stamping, resulting in a close fit between the workpiece and the inner wall of the mold, which makes it inconvenient for the staff to take the stamped workpiece out of the mold, thereby greatly reducing the stamping efficiency.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] In order to facilitate the staff to remove the workpiece from the mold, a mechanism is set up to eject the workpiece after stamping. However, the workpiece after ejection still remains in the mold, and the staff still needs to manually move it elsewhere before the subsequent stamping work can be carried out. When the number of workpieces that need to be stamped is large, the process of manual removal of the workpieces by the staff is correspondingly increased, which increases the labor intensity of the staff. In addition, the workpieces manually removed by the staff may be placed randomly in the surrounding area, which will cause the distribution of multiple workpieces to be not uniform. When the workpieces need to be collected centrally, omissions are prone to occur, which is not conducive to the transportation of workpieces. Moreover, when the workpieces are piled together in a disorderly manner, it is inconvenient for the staff to record and count the stamping quality and quantity of the workpieces, which affects the subsequent process. Manual sorting of the workpieces will also increase the labor intensity of the staff.

[0006] To this end, the present invention provides a mold punching device that is easy to demould. Summary of the invention

[0017] Preferably, a support plate is fixedly connected to one side of the upper end surface of the flip plate, and a plurality of pressing plates are plugged and slidably connected to the support plate.

[0018] Preferably, a spring is fixedly connected to one side of the upper end of the pressing plate, and the lower end of the spring is fixedly connected to the upper end surface of the support plate.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The mold stamping device for easy demoulding described in the present invention, after the workpiece is stamped and formed, by starting the motor four to drive the threaded rod three to rotate, the connecting rod slides from right to left on the workbench, and the end of the connecting rod is used to push the workpiece in the lower mold, so that it can slide out from the inner wall of the lower mold, thereby avoiding the situation where the workpiece is squeezed and causes it to fit tightly with the inner wall of the lower mold and is difficult to remove, thereby improving the efficiency of subsequent stamping work.

[0023] 2. The mold stamping device for easy demoulding described in the present invention utilizes an anti-stuck arrangement and placement mechanism. When the U-shaped workpiece is ejected by the demoulding rod, the U-shaped workpiece can just enter the U-shaped placement groove formed by the outer plate and the inner plate, so that the U-shaped workpiece can be arranged and placed, eliminating the need for workers to manually remove the pushed-out workpieces, reducing the labor intensity of the workers, and under the limitation of the U-shaped placement groove, the workpieces are also relatively neat, which is convenient for the workers to record and unify the stamping quality and quantity of the workpieces, which is beneficial to the subsequent workpiece processing procedures, and when it is necessary to When taking out the workpiece in the U-shaped placement groove, it is only necessary to place the collection container under one side of the workbench, and then drive the flip plate to rotate to tilt the U-shaped placement groove, so that the workpiece in the U-shaped placement groove can fall into the collection container, thereby realizing the centralized collection of the workpieces without omission, which is conducive to the transfer of the workpieces, etc., and when the workpiece slips out of the U-shaped placement groove, the push block can be driven to move, so that the push block passes through the through groove and extends into the U-shaped placement groove, and then the push block is driven to move from left to right to push the workpiece in the U-shaped placement groove to promote the falling of the workpiece, thereby This avoids the situation where the workpiece is stuck in the U-shaped placement groove due to friction and cannot fall normally, thereby ensuring the normal collection of the workpiece. In addition, when the stamped workpieces need to be collected in different containers in batches, each time a workpiece is moved to the U-shaped placement groove by the demoulding rod, the push plate moves to the right and squeezes a pressing piece. After being squeezed by the end of the push plate, the pressing piece moves downward. When the bottom of the pressing piece contacts the upper end of the outer plate, it will have a blocking effect on the workpiece. Each time a workpiece enters the U-shaped placement groove, a pressing piece will drop, so that multiple workpieces can be separated. When the workpieces need to be collected, the push plate is driven to move and the pressing plates are reset in turn, so that the number of workpieces that fall can be controlled, thereby realizing the distribution of the number of workpieces, and then meeting different transportation and storage needs. At the same time, when some workpieces fall, if the workpieces are stuck, the stuck workpieces can be pushed by the push block. Moreover, since the workpieces have been separated from each other, when the push block pushes the workpieces, the workpieces that need to fall and the workpieces that do not need to fall will not fit together, and the push block will not be able to extend into the gap between the two, thereby ensuring the normal operation of the push block.

DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Please refer to Figure 1-Figure 8 The present invention provides a technical solution: a mold stamping device that is easy to demould, comprising a workbench 1, a lower mold 6 is fixedly connected to the middle of the upper end surface of the workbench 1, a plurality of sliding rods 4 5 are fixedly connected to the middle of the upper end surface of the workbench 1, a top plate 2 is connected to the upper end of the sliding rods 4 5, an upper mold 4 is slidably connected to the sliding rods 4 5, a punch 28 is fixedly connected to one side of the lower end surface of the upper mold 4, and a demoulding mechanism for pushing a workpiece out of the lower mold 6 is provided on the workbench 1;

[0036] The demoulding mechanism comprises a connecting rod 7 slidably connected to the right side of the upper end surface of the workbench 1, and two demoulding rods 31 are arranged on one side of the left end surface of the connecting rod 7;

[0037] The workbench 1 is also provided with an anti-stuck arrangement and placement mechanism for receiving the removed workpieces;

[0038] The anti-stuck arrangement and placement mechanism includes a fixed block 17 fixedly connected to the front and rear ends of the left side of the upper end surface of the workbench 1, a flip plate 32 is rotatably provided on one side of the fixed block 17, an outer plate 20 and an inner plate 26 are fixedly connected to the right end surface of the flip plate 32, a through groove 25 is provided on one side of the outer plate 20, and a U-shaped placement groove is formed between the outer plate 20 and the inner plate 26.

[0039] In this embodiment, Figure 1 , Figure 6-Figure 8 As shown, one end of the lower side of the connecting rod 7 is threadedly connected to a threaded rod three 29, both ends of the threaded rod three 29 are rotatably set on the workbench 1, and one side of the upper end surface of the workbench 1 is fixedly connected to a motor four 30, and the output end of the motor four 30 is fixedly connected to one end of the threaded rod three 29.

[0040] A hydraulic cylinder 3 is fixedly connected to one side of the upper end surface of the top plate 2 , and a piston end of the hydraulic cylinder 3 is fixedly connected to one side of the upper end surface of the upper die 4 .

[0041] Specifically, the sheet workpiece to be stamped is placed on the lower die 6, and then the hydraulic cylinder 3 is used to drive the upper die 4 to descend, and the punch 28 is used to stamp the workpiece so that the workpiece is embedded in the inner wall of the lower die 6. At this time, the workpiece becomes U-shaped, and then the punch 28 is driven to reset. Since the workpiece is squeezed, the workpiece fits tightly with the inner cavity of the lower die 6, which makes it inconvenient for the staff to take out the workpiece. Therefore, the motor four 30 can be started to drive the threaded rod three 29 to rotate, so that the connecting rod 7 slides from right to left on the workbench 1, and the end of the connecting rod 7 can be used to push the workpiece in the lower die 6, so that it can slide out from the inner wall of the lower die 6, thereby avoiding the situation where the workpiece is squeezed and the inner wall of the lower die 6 is tightly fitted and difficult to take out, thereby improving the efficiency of subsequent stamping work.

[0043] A fixed plate 12 is fixedly connected to one side of the left end surface of the flip plate 32, a sliding rod 11 is fixedly connected to one side of the left end surface of the fixed plate 12, the sliding rod 11 is slidably connected to the push plate 8, and the right end of the sliding rod 11 is fixedly connected to one side of the left end surface of the flip plate 32.

A motor 9 is fixedly connected to one side of the left end surface of the fixed plate 12, and the output end of the motor 9 is fixedly connected to one end of the threaded rod 10.

[0045] A support plate 13 is fixedly connected to one side of the upper end surface of the flip plate 32 , and a plurality of pressing sheets 14 are inserted and slidably connected to the support plate 13 .

[0046] A spring 27 is fixedly connected to one side of the upper end of the pressing plate 14 , and the lower end of the spring 27 is fixedly connected to the upper end surface of the supporting plate 13 .

[0047] A slide rod 21 is fixedly connected to one side of the right end face of the flip plate 32, and a threaded block 22 is slidably connected to the slide rod 219. Slide rods 3 23 are slidably connected to both sides of the threaded block 22. One end of the slide rod 3 23 is fixedly connected to a push block 21. An electric push rod 24 is fixedly connected to one side of the front end face of the threaded block 22. The piston end of the electric push rod 24 is fixedly connected to one side of the push block 21.

[0048] One end of the threaded block 22 is threadedly connected to the threaded rod 2 18 , and the left end of the threaded rod 2 18 is rotatably set on the flip plate 32 . The left end surface of the flip plate 32 is fixedly connected to the motor 2 15 , and the output end of the motor 2 15 is fixedly connected to one end of the threaded rod 2 18 .

[0049] Specifically, in the existing stamping device, in order to facilitate the staff to take the workpiece out of the mold, a mechanism is set to eject the workpiece after stamping. However, the workpiece after ejection still stays at the mold, and the staff still needs to manually move it to another place before the subsequent stamping work can be carried out. When the number of workpieces to be stamped is large, the process of manual removal of the workpiece by the staff is correspondingly increased, which increases the labor intensity of the staff. In addition, the workpieces manually removed by the staff may be randomly placed in the periphery, which will cause the distribution of multiple workpieces to be not uniform. When the workpieces need to be collected in a centralized manner, omissions are likely to occur, which is not conducive to the transportation of the workpieces. Moreover, when the workpieces are piled up in a disorderly manner, it is inconvenient for the staff to record and count the stamping quality and quantity of the workpieces, which affects the subsequent process. When the workpieces are manually sorted, the labor intensity of the staff will also be increased.

[0050] Therefore, in order to solve the above problems, the present embodiment is used for the formed U-shaped workpiece when in use. When the U-shaped workpiece is ejected by the demoulding rod 31, the U-shaped workpiece can just enter the U-shaped placement groove formed by the outer plate 20 and the inner plate 26. Then, the above operation is repeated, so that the stamped U-shaped workpieces can all enter the U-shaped placement groove, and the distance moved by the demoulding rod 31 each time is different, so that the U-shaped workpieces can be arranged and placed. Moreover, under the limit of the U-shaped placement groove, the workpieces are also relatively neat, which is convenient for the staff to record and unify the stamping quality and quantity of the workpieces, which is beneficial to the subsequent workpiece processing procedures. Moreover, when it is necessary to take out the workpieces in the U-shaped placement groove, it is only necessary to place the collection container under one side of the workbench 1, and then use the motor 3 16 to drive the flip plate 32 to rotate, so that the U-shaped placement groove is tilted, so that the workpieces in the U-shaped placement groove can fall into the collection container, thereby realizing the centralized collection of the workpieces without omission, which is beneficial to the transportation of the workpieces.

[0051] When the workpiece slides down from the U-shaped placement groove, the workpiece may be stuck in the U-shaped placement groove due to friction, thereby affecting the normal falling of the workpiece. Therefore, when the workpiece slides down from the U-shaped placement groove, the electric push rod 24 can be used to drive the push block 21 to move, so that the push block 21 passes through the through groove 25 and extends into the U-shaped placement groove, and then the motor 15 is used to drive the threaded rod 18 to rotate, so that the push block 21 moves from left to right to push the workpiece in the U-shaped placement groove to promote the falling of the workpiece, thereby avoiding the situation that the workpiece is stuck in the U-shaped placement groove due to friction and cannot fall normally, thereby ensuring the normal progress of the workpiece collection work;

[0052] In some cases, it is necessary to collect the stamped workpieces in different containers to realize the distribution of the number of workpieces to meet different transportation and storage requirements. However, when the workpieces slide from the U-shaped placement groove to the container at one time, the distribution of the number of workpieces cannot be realized. Therefore, in order to solve this problem, when this embodiment is used, every time a workpiece is moved to the U-shaped placement groove through the demoulding rod 31, the motor 9 will drive the threaded rod 10 to rotate, so that the push plate 8 moves to the right and squeezes a pressing sheet 14. Since the upper side of the pressing sheet 14 is an inclined surface, the pressing sheet 14 is pressed by the push plate 8. After the end is squeezed, it will move downward, and the spring 27 is compressed. Since the upper end of the workpiece passes over the upper end of the outer plate 20, when the bottom of the pressing plate 14 contacts the upper end of the outer plate 20, it will have a blocking effect on the workpiece, and then repeat the above operation. Whenever a workpiece enters the U-shaped placement groove, a pressing plate 14 will drop, so that multiple workpieces can be separated. When the workpiece needs to be collected, the push plate 8 is driven to move, and the pressing plate 14 is reset in turn, so that the number of dropped workpieces can be controlled, thereby realizing the distribution of the number of workpieces, and then meeting different transportation and storage requirements;

[0053] Furthermore, when part of the workpiece falls, if the workpiece is stuck, the stuck workpiece can be pushed by the push block 21. Moreover, since the workpieces have been separated from each other, when the push block 21 pushes the workpiece, the workpiece that needs to fall and the workpiece that does not need to fall will not fit together, and the push block 21 will not be able to extend into the gap between the two, thereby ensuring the normal operation of the push block 21.

[0054] Working principle: Place the sheet workpiece to be stamped on the lower die 6, then use the hydraulic cylinder 3 to drive the upper die 4 to descend, use the punch 28 to stamp the workpiece, so that the workpiece is embedded in the inner wall of the lower die 6. At this time, the workpiece becomes a U-shape, and then drive the punch 28 to reset. Since the workpiece is squeezed, the workpiece fits tightly with the inner cavity of the lower die 6, which is inconvenient for the staff to take out the workpiece. Therefore, the motor 4 30 can be started to drive the threaded rod 3 29 to rotate, so that the connecting rod 7 slides from right to left on the workbench 1, and the end of the connecting rod 7 can be used to push the workpiece in the lower die 6, that is, The U-shaped workpiece can be made to slide out from the inner wall of the lower die 6, thereby avoiding the situation where the workpiece is tightly fitted to the inner wall of the lower die 6 and difficult to be taken out due to being squeezed, thereby improving the efficiency of subsequent stamping work. When the U-shaped workpiece is ejected by the demoulding rod 31, the U-shaped workpiece can just enter the U-shaped placement groove formed by the outer plate 20 and the inner plate 26, and then repeat the above operation, so that the U-shaped workpiece after stamping can all enter the U-shaped placement groove, and the distance moved by the demoulding rod 31 each time is different, so that the U-shaped workpieces can be arranged and placed, and under the limitation of the U-shaped placement groove, the workpieces are also relatively neat, which is convenient for work. The workers can record and unify the stamping quality and quantity of the workpieces, which is beneficial to the subsequent workpiece processing procedures. Moreover, when the workpieces in the U-shaped placement groove need to be taken out, it is only necessary to place the collection container under one side of the workbench 1, and then use the motor 3 16 to drive the flip plate 32 to rotate, so that the U-shaped placement groove is tilted, and the workpieces in the U-shaped placement groove can fall into the collection container, thereby realizing the centralized collection of the workpieces without omission, which is beneficial to the transportation of the workpieces. When the workpiece slides down from the U-shaped placement groove, it may be blocked by friction. The workpiece may be stuck in the U-shaped placement groove, thereby affecting the normal falling of the workpiece. Therefore, when the workpiece slides out of the U-shaped placement groove, the electric push rod 24 can be used to drive the push block 21 to move, so that the push block 21 passes through the through groove 25 and extends into the U-shaped placement groove, and then the motor 15 is used to drive the threaded rod 18 to rotate, so that the push block 21 moves from left to right to push the workpiece in the U-shaped placement groove to promote the falling of the workpiece, thereby avoiding the situation that the workpiece is stuck in the U-shaped placement groove due to friction and cannot fall normally, thereby ensuring the normal progress of the workpiece collection work;In some cases, it is necessary to collect the stamped workpieces in different containers to achieve the distribution of the number of workpieces to meet different transportation and storage needs. However, when the workpieces slide from the U-shaped placement groove to the container at one time, the distribution of the number of workpieces cannot be achieved. Therefore, in order to solve this problem, when this embodiment is in use, every time a workpiece is moved into the U-shaped placement groove through the demolding rod 31, the motor 9 will drive the threaded rod 10 to rotate, so that the push plate 8 moves to the right and squeezes a pressing piece 14. Since the upper side of the pressing piece 14 is an inclined surface, the pressing piece 14 will move downward after being squeezed by the end of the push plate 8, and the spring 27 will be compressed. Since the upper end of the workpiece passes over the upper end of the outer plate 20, when the bottom of the pressing piece 14 contacts the upper end of the outer plate 20, the workpiece will be pressed. The parts play a blocking effect, and then repeat the above operation. Whenever a workpiece enters the U-shaped placement groove, a pressing plate 14 will descend to separate multiple workpieces. When the workpieces need to be collected, the push plate 8 is driven to move, and the pressing plate 14 is reset in turn, so that the number of dropped workpieces can be controlled, thereby realizing the distribution of the number of workpieces, and then meeting different transportation and storage needs; and when some workpieces fall, if the workpieces are stuck, the stuck workpieces can be pushed by the push block 21, and because the workpieces have been separated from each other, when the push block 21 pushes the workpiece, the workpiece that needs to fall and the workpiece that does not need to fall will not be attached, and the push block 21 cannot extend into the gap between the two, thereby ensuring the normal operation of the push block 21. ;

[0055] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
