Description

Technical Field

[0001] The present invention relates to the technical field of stamping dies, and particularly to a waste discharging die and its process. Background Art

[0002] A stamping die is a special process equipment for processing materials into parts (or semi-finished products) in cold stamping processing, called a cold stamping die. Stamping is a pressure processing method in which, at room temperature, a die installed on a press applies pressure to a material to cause separation or plastic deformation, thereby obtaining the required parts. Depending on the different product processing methods, the dies can be divided into five categories: punching and shearing dies, bending dies, drawing dies, forming dies, and compression dies. With the rapid development of the national economy, the market demand for dies is increasing continuously.

[0003] As the requirements for automated production in enterprise production are getting higher and higher, especially for the punching die of sheet metal parts, waste materials will fall on the die during stamping, affecting subsequent continuous stamping production. To solve the above technical problems, relevant patents have been proposed in the prior art. For example, the patent with the authorization announcement number CN217095251U and the name of a stamping die convenient for waste discharging discloses a stamping die convenient for waste discharging, including an upper die, a lower die, and a bottom plate. The upper die is located above the lower die, and the lower die is located above the bottom plate. The upper die is provided with a punching head, and the lower die is provided with a waste discharging hole corresponding to the punching head; a waste discharging groove is installed on the lower die, the waste discharging groove is located below the waste discharging hole, and the waste discharging groove is communicated with the waste discharging hole. The side wall of the waste discharging groove is provided with an air inlet, a cavity, and a plurality of air outlets. The air inlet is communicated with the cavity, the cavity is communicated with the plurality of air outlets, and the air outlets are inclined from both sides of the waste discharging groove towards the center along the direction of waste material discharge.

[0004] Another example is the Chinese patent with the authorization number CN221211935U and the name of a waste discharging die for die cutting. The above patent discloses a waste discharging die for die cutting, including a substrate and a trimming hole cutter. The trimming hole cutter is embedded on the substrate, and a waste discharging hole is opened on the substrate. The trimming hole cutter includes a cutter body and a cutting edge. The cutting edge is fixedly connected to the upper end of the cutter body, and the upper end of the cutting edge is a certain distance higher than the upper surface of the substrate. A waste discharging groove is arranged on the side wall of the cutter body, the cutting edge is communicated with the waste discharging groove, and the waste discharging hole is communicated with the waste discharging groove. In the above patent, a waste discharging hole is opened on the side of the trimming hole cutter, and waste paper edge materials fall from the waste discharging hole, preventing the waste paper edge materials from remaining near the trimming hole cutter. The structure cost is low, and the use effect is good.

[0005] The prior art, including the above-mentioned patent, can meet the waste discharge needs of the mold to a certain extent. It is known that in order to meet the waste discharge needs of the waste chips, a through groove is generally opened on the template. At this time, the waste chips will directly pass through the through groove and fall into a predetermined area after being punched out, so as to facilitate the collection of the waste chips. However, in the prior art, when the waste chips fall into the waste chip collection space, there is still the problem of inconvenience in cleaning. At this time, in order to effectively clean the waste chips, the prior art can only use dust removal mechanisms such as vacuum cleaners to discharge the waste, which has certain shortcomings. Summary of the invention

[0006] The object of the present invention is to provide a waste discharge mold and a process thereof to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a waste discharge mold, including a mold frame, an upper mold plate and a lower mold plate are respectively installed on the upper and lower sides of the mold frame, and an upper cutting mold is installed on the upper mold plate, and a lower cutting mold is installed on the lower mold plate, and a power cylinder for driving the upper mold plate to slide vertically is installed on the mold frame; a material storage trough is provided inside the mold frame, and a leakage hole communicated with the material storage trough is provided on the lower mold plate; a cleaning mechanism is slidably connected inside the material storage trough, and the cleaning mechanism is connected to the upper mold plate through a linkage mechanism; when the power cylinder drives the upper mold plate to move upward, the cleaning mechanism is driven by the linkage mechanism to slide back and forth inside the mold frame to clean the inside of the material storage trough.

[0008] Furthermore, the cleaning mechanism includes a cleaning plate slidably connected to the inside of the mold frame, and a driving unit for driving the cleaning plate to slide back and forth inside the material storage tank is provided inside the mold frame.

[0009] Furthermore, the driving unit includes a reciprocating power screw that is rotatably connected to the mold frame, and a threaded sleeve that is connected to the reciprocating thread is fixedly connected to the cleaning plate.

[0010] Furthermore, the linkage mechanism includes a linkage rod rotatably connected to the mold frame, the linkage rod is threadedly connected to the reciprocating power screw through an intermittent clamping piece; and a spur gear is installed on the linkage rod, and a rack is installed on the upper mold plate through an elastic unit, the rack is slidably connected to the mold frame, and the rack is meshed with the spur gear.

[0011] Furthermore, the intermittent clamping part includes a clamping rod slidably connected to the reciprocating power screw, and an extrusion spring is arranged between the clamping rod and the reciprocating screw, and a wedge-shaped groove adapted to the clamping rod is opened inside the linkage rod, and the elastic force of the extrusion spring drives the clamping rod to be clamped in the wedge-shaped groove.

[0012] Furthermore, there are two reciprocating power screw rods, which are rotatably connected to two sides of the mold frame respectively, and the two reciprocating power screw rods are transmission-connected via a synchronous member.

[0013] Furthermore, the elastic unit includes an installation cylinder fixedly connected to the upper template. A vertical rod is fixedly connected to the rack. The vertical rod is slidably connected to the installation cylinder, and a buffer spring is arranged between the vertical rod and the installation cylinder.

[0014] Furthermore, an installation groove is formed in the side wall of the mold base. A storage frame is slidably connected inside the installation groove. The storage frame is slidably connected to the mold base through a limiting part.

[0015] Furthermore, a clamping part for fixing the storage frame is also arranged between the storage frame and the mold base. The clamping part includes a card strip made of elastic material fixedly connected to the storage frame. A card slot adapted to the card strip is formed in the mold base. The card strip is in clamping fit with the card slot.

[0016] A waste discharging process specifically includes the following steps:

[0017] S1: Install the workpiece to be punched on the lower die.

[0018] S2: The power cylinder drives the upper template to drive the upper die to move downward. The upper die and the lower die cooperate to perform a punching operation on the workpiece. During the punching stroke, the upper die drops the waste material from the material leakage hole into the storage tank inside the mold base.

[0019] S3: After the punching operation is completed, during the upward movement stroke of the power cylinder driving the upper template, the intermittent clamping part drives the reciprocating power lead screw to rotate, driving the cleaning mechanism to move back and forth inside the storage tank to perform a cleaning operation on the inside of the storage tank.

[0020] S4: When the cleaning mechanism moves inside the storage tank, it will clean the waste material into the storage frame.

[0021] S5: Regularly drive the clamping part to unlock the storage frame, and pour the waste material inside the storage frame to achieve the waste discharging operation.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: In the working process of the waste discharging die and its process, when the workpiece is placed at the established stamping station, the power cylinder is started, and the power cylinder drives the upper template to move downward to perform stamping operations on the workpiece. During this process, the waste will enter the inside of the storage tank through the material leakage hole. At this moment, there will be no waste remaining between the upper die and the lower die, which can improve the cleaning efficiency of the waste and have a better use effect. After the stamping of the workpiece is completed, it is necessary to use the power cylinder to drive the upper template to drive the upper die to reset. During this process, when the power cylinder drives the upper template to move upward, the cleaning mechanism is driven by the linkage mechanism to reciprocate and slide inside the die holder to clean the inside of the storage tank, so that the waste can be cleaned to the established area. At this moment, it can also avoid the accumulation of waste inside the storage tank and further improve the waste discharging efficiency of the die. Therefore, only by regularly storing the waste inside the storage tank can the waste discharging operation of the die be realized, without the need to separately use a dust suction mechanism to clean the waste, improving the work efficiency.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0036] See also Figures 1 - 10 The present invention provides a technical solution: a waste discharge mold, comprising a mold frame 1, an upper mold plate 2 and a lower mold plate 3 are respectively installed on the upper and lower sides of the mold frame 1, and an upper cutting mold 4 is installed on the upper mold plate 2, and a lower cutting mold 5 is installed on the lower mold plate 3, and a power cylinder 6 for driving the upper mold plate 2 to slide vertically is installed on the mold frame 1; a material storage tank 7 is provided inside the mold frame 1, and a leakage hole 8 communicated with the material storage tank 7 is provided on the lower mold plate 3; a cleaning mechanism is slidably connected inside the material storage tank 7, and the cleaning mechanism is connected to the upper mold plate 2 through a linkage mechanism; when the power cylinder 6 drives the upper mold plate 2 to move upward, the cleaning mechanism is driven to slide back and forth inside the mold frame 1 through the linkage mechanism to clean the inside of the material storage tank 7.

[0037] Specifically, the waste discharge mold includes a mold frame 1, and a plurality of support members 23 are arranged on the bottom of the mold frame 1. The support members 23 include support feet fixedly connected to the bottom of the mold frame 1, and anti-skid pads are arranged at the bottom of the support feet, so as to improve the stability of the mold during operation and achieve better use effect. The upper and lower sides of the mold frame 1 are respectively installed with an upper mold plate 2 and a lower mold plate 3, and an upper cutting mold 4 is installed on the upper mold plate 2, and a lower cutting mold 5 is installed on the lower mold plate 3. Specifically, the installation method of the upper cutting mold 4 being installed on the upper mold plate 2 and the lower cutting mold 5 being installed on the lower mold plate 3 are both prior arts and will not be described in detail here. The mold frame 1 is installed with a power cylinder 6 for driving the upper mold plate 2 to slide vertically, which provides power for the upper cutting mold 4 and the lower cutting mold 5 to perform stamping operations to meet work needs. A material storage trough 7 is provided inside the mold frame 1, and a material leakage hole 8 which is connected to the material storage trough 7 is provided on the lower mold plate 3. At this moment, after the stamping of the workpiece is completed, the waste material will enter the material storage trough 7 from the material leakage hole 8, so as to meet the collection of the waste material and avoid the waste material from accumulating between the upper cutting die 4 and the lower cutting die 5. At this moment, in order not to affect the subsequent stamping operation, a lot of time is needed to clean the waste material. At this moment, after the waste material enters the material storage trough 7 through the material leakage hole 8, no waste material will remain between the upper cutting die 4 and the lower cutting die 5, thereby improving the cleaning efficiency of the waste material and achieving a better use effect.

[0038] The storage tank 7 is slidably connected with a cleaning mechanism, and the cleaning mechanism is connected to the upper template 2 through a linkage mechanism. Therefore, when the power cylinder 6 drives the upper template 2 to move upward, the cleaning mechanism is driven to slide inside the storage tank 7 through the linkage mechanism to clean the waste inside the storage tank 7. More specifically, during the working process, when the workpiece is placed in a predetermined stamping station, the power cylinder 6 is started, and the power cylinder drives the upper template 2 to move downward to stamp the workpiece. During this process, the waste will enter the storage tank 7 from the leakage hole 8. At this time, no waste will remain between the upper cutting die 4 and the lower cutting die 5, thereby improving the cleaning efficiency of the waste and achieving a better use effect. After the workpiece is stamped, the power cylinder 6 is needed to drive the upper template 2 to drive the upper cutting die 4 to reset. During this process, when the power cylinder 6 drives the upper template 2 to move upward, the linkage mechanism drives the cleaning mechanism to slide back and forth inside the mold frame 1 to clean the inside of the storage tank 7, so that the waste can be cleaned to a predetermined area. At this moment, it can also avoid the accumulation of waste inside the storage tank 7, further improving the waste discharge efficiency of the mold.

[0039] In the embodiments provided by the present invention, the cleaning mechanism includes a cleaning plate 13 slidably connected inside the mold base 1. Cleaning bristles are provided at the bottom of the cleaning plate 13. When the cleaning plate 13 slides, it will drive the cleaning bristles to slide, so as to clean the waste chips to meet the working needs. And a driving unit for driving the cleaning plate 13 to reciprocally slide inside the storage tank 7 is provided inside the mold base 1. The driving unit drives the cleaning bristles to reciprocally slide, so that the cleaning operation of the waste in the storage tank 7 can be realized.

[0040] In the embodiments provided by the present invention, the driving unit includes a reciprocating power lead screw 15 rotatably connected to the mold base 1. A threaded sleeve 14 threadedly connected to the reciprocating thread is fixedly connected to the cleaning plate 13. Therefore, when the reciprocating power lead screw 15 rotates, it will drive the cleaning plate 13 to slide through the threaded sleeve 14 to clean the waste, and the use effect is better.

[0041] In the embodiments provided by the present invention, the linkage mechanism includes a linkage rod 18 rotatably connected to the mold base 1. The linkage rod 18 is threadedly connected to the reciprocating power lead screw 15 through an intermittent clamping member 24. That is, when the upper template 2 moves downward, at this moment, the intermittent clamping member 24 cannot drive the reciprocating power lead screw 15 to rotate. On the contrary, when the upper template 2 moves upward, it can drive the reciprocating power lead screw 15 to rotate through the intermittent clamping member 24. Therefore, when the reciprocating power lead screw 15 rotates, it will drive the cleaning plate 13 to slide through the threaded sleeve 14 to clean the waste, and the use effect is better. And a spur gear 17 is installed on the linkage rod 18, and a rack 16 is installed on the upper template 2 through an elastic unit. The rack 16 is slidably connected to the mold base 1, and the rack 16 meshes with the spur gear 17. Therefore, during use, when the upper template 2 moves upward, it will drive the linkage rod 18 to rotate through the cooperation between the rack 16 and the spur gear 17. When the linkage rod 18 rotates, it drives the reciprocating power lead screw 15 to rotate through the intermittent clamping member 24. Therefore, when the reciprocating power lead screw 15 rotates, it will drive the cleaning plate 13 to slide through the threaded sleeve 14 to clean the waste.

[0042] In the embodiments provided by the present invention, the intermittent clamping member 24 includes a clamping rod 241 slidably connected inside the reciprocating power lead screw 15. A compression spring 243 is provided between the clamping rod 241 and the reciprocating lead screw. And a wedge-shaped groove 242 adapted to the clamping rod 241 is formed inside the linkage rod 18. The elastic force of the compression spring 243 drives the clamping rod 241 to be clamped in the wedge-shaped groove 242. Specifically, the clamping rod 241 is a wedge-shaped rod. When the wedge surface of the wedge-shaped rod abuts against the wedge-shaped groove 242, at this moment, the linkage rod 18 cannot drive the reciprocating power lead screw 15 to rotate during the rotation process, so that the cleaning plate 13 maintains a fixed state.

[0043] In the embodiment provided by the present invention, there are two reciprocating power screws 15, which are rotatably connected to the two sides of the mold frame 1 respectively. The two reciprocating power screws 15 are connected by a synchronous member 19, wherein the synchronous member 19 is a prior art, which is specifically a pulley assembly. When one of the reciprocating power screws 15 rotates, it will drive the other reciprocating power screw 15 to rotate, further improving the stability of the cleaning plate 13 when sliding, thereby indirectly improving the cleaning efficiency of the waste.

[0044] In the embodiment provided by the present invention, the elastic unit includes a mounting tube 21 fixedly connected to the upper template 2, a vertical rod 20 fixedly connected to the rack 16, the vertical rod 20 is slidably connected to the mounting tube 21, and a buffer spring 22 is arranged between the vertical rod 20 and the mounting tube 21. At this moment, when the upper template 2 moves downward, it will move downward through the rack 16 and the vertical rod 20, and then it can be raised, so that the rack 16 and the spur gear 17 are engaged to drive the linkage rod 18 to rotate. Specifically, when the rack 16 moves downward to a predetermined position, and the upper template 2 has not yet reached the predetermined position, the vertical rod 20 at this moment will squeeze the buffer spring 22 backward into the mounting tube 21 to avoid motion interference.

[0045] In the embodiment provided by the present invention, a mounting groove 11 is provided on the side wall of the mold frame 1, and a storage frame 9 is slidably connected inside the mounting groove 11, and the storage frame 9 is slidably connected to the mold frame 1 through a limiting portion 10. Specifically, the limiting portion 10 includes a positioning block fixedly connected to the side wall of the storage frame 9, a positioning rod is fixedly connected to the mold frame 1, a through slot is provided on the positioning block, and the positioning rod is slidably connected to the positioning block through the through slot, so as to improve the stability of the storage frame 9 when sliding, and the use effect is better.

[0046] In the embodiment provided by the present invention, a clamping portion 12 for fixing the storage frame 9 is further provided between the storage frame 9 and the mold frame 1, and the clamping portion 12 includes a clamping strip 121 of elastic material fixedly connected to the storage frame 9, and a clamping slot 122 adapted to the clamping strip 121 is provided on the mold frame 1, and the clamping strip 121 is clamped and matched with the clamping slot 122. Therefore, during use, when the storage frame 9 is installed in the installation slot 11, the clamping strip 121 at this moment will be clamped into the clamping slot 122, and the storage frame 9 will be installed in the mold frame 1. On the contrary, when the storage frame 9 slides out from the installation slot 11, the clamping strip 121 slides out from the clamping slot 122, and the storage frame 9 can slide out from the mold frame 1, so that the waste material inside the storage frame 9 can be removed conveniently to meet the work needs.

[0047] The present invention also provides a waste discharge process, which specifically comprises the following steps:

[0048] S1: Install the workpiece to be punched on the lower die 5;

[0049] S2: The power cylinder 6 drives the upper template 2 to drive the upper die 4 to move downward. The upper die 4 cooperates with the lower die 5 to perform a stamping operation on the workpiece. During the stamping stroke, the upper die 4 drops the waste material from the material leakage hole 8 into the storage tank 7 inside the die holder 1;

[0050] S3: After the stamping operation is completed, during the upward movement stroke of the power cylinder 6 driving the upper template 2, the intermittent clamping member 24 drives the reciprocating power lead screw 15 to rotate, driving the cleaning mechanism to move back and forth inside the storage tank 7 to perform a cleaning operation on the inside of the storage tank 7;

[0051] S4: When the cleaning mechanism moves inside the storage tank 7, it will clean the waste material into the storage frame 9;

[0052] S5: Periodically drive the clamping portion 12 to unlock the storage frame 9, and dump the waste material inside the storage frame 9 to achieve the waste discharging operation.

[0053] It should be noted that the electrical equipment involved in this application can be powered by a storage battery or an external power supply.

[0054] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, terms such as "installation", "provided with", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0055] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
