Description

Technical Field

[0001] The invention relates to a shaping structure of a metal powder injection molding part, in particular to a high-efficiency automatic shaping system for a metal powder injection molding part. Background Art

[0002] Metal powder injection molded parts need to be sintered in the later stage. The sintering principle is: the residual binder components in the metal powder injection molded parts are cracked into gas during the heating process. At a high temperature close to the melting point of the metal, the metal atoms will migrate between different powder particles, resulting in sintering. The original loose powder accumulation becomes dense, and the volume of the parts becomes smaller and the strength becomes higher after sintering.

[0003] The smaller the volume of the sintered product, the smaller the size. The structure of the product, uneven thickness, the state of the product during sintering, and a series of other reasons may cause some dimensions of the product to exceed the tolerance.

[0004] For some products with out-of-tolerance dimensions, mold shaping is generally used to improve the dimensions. The traditional shaping method is to manually put the product into the shaping mold, and the mold is pressed up and down by a shaping hydraulic machine to improve the product size.

[0005] In addition, the shaping of metal powder injection molded parts is generally divided into two procedures. The first procedure is to shape the outer width and inner width, and the second procedure is to shape the plane.

[0006] The above shaping method has the following problems:

[0007] (1) Due to manual operation, the shaping method is inefficient, has high labor costs, and is unsafe;

[0008] (2) Two sets of molds are required for shaping, so the cost is very high. Summary of the invention

[0027] By adopting the above technical solution, each hopper is equipped with two chutes for material transportation, thereby further improving the material transportation efficiency.

[0028] In a preferred example, the present invention can be further configured as follows: the height of one end of the rectangular platform connected to the hopper is higher than the height of the other end.

[0029] By adopting the above technical solution, the rectangular platform is set to be inclined for material transportation, and there is no need to set up a conveyor belt, which saves costs.

DETAILED DESCRIPTION

[0050] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0051] See also Figure 1 and Figure 4The present invention provides a highly efficient automatic shaping system for metal powder injection molding parts, which includes a material screening mechanism 100, a material transporting mechanism 200, a shaping mold mechanism 300, a material receiving plate 400, a material shifting mechanism 500 and a controller 600.

[0052] The screening mechanism 100 is used to store the metal powder injection molding parts to be shaped and to arrange the metal powder injection molding parts to be shaped in a uniform, orderly and directional manner, so as to facilitate the transportation of the material transport mechanism 200 .

[0053] The screening mechanism 100 specifically includes two identical bases 110 , each base 110 is provided with a hopper 120 , and the material transport efficiency can be improved by adopting a double hopper structure.

[0054] The base 110 can be specifically a rectangular frame, on which a vibration structure 111 is provided, and a hopper 120 is arranged on the vibration structure 111. The hopper 120 can vibrate along with the vibration structure 111, and the metal powder injection molded parts to be shaped can be placed in the hopper 120. A spiral track 121 is provided in the hopper 120. When the hopper 120 vibrates, the metal powder injection molded parts to be shaped in the hopper 120 can rise along the spiral track 121, thereby being transported to the material transport mechanism 200.

[0055] Since the metal powder injection molded parts to be shaped rise along the spiral track 121 , the metal powder injection molded parts to be shaped can be arranged in an orderly manner.

[0056] The vibration structure 111 may be an existing structure, including a vibration disk and a pulse electromagnet. The vibration disk is arranged on the base 110, and the pulse electromagnet is arranged on the bottom surface of the hopper 120. After the vibration disk is powered on, the pulse electromagnet can make the hopper 120 vibrate vertically and torsionally.

[0057] In addition, four support rods 112 are provided at the bottom of the base 110, and a truncated cone-shaped support block 113 is provided at the bottom of each support rod 112. The support block 113 is in contact with the ground to improve the stability of the base 110 and prevent the vibration structure 111 from causing the base 110 to shake.

[0058] The support block 113 may specifically be a suction cup structure, which can further improve the stability of the base 110 .

[0059] In addition, the support rod 112 may be a telescopic structure, which makes it easy to adjust the height of the base 110.

[0060] The material transport mechanism 200 is connected to the material screening mechanism 100 and is used to transport the metal powder injection molding parts to be shaped transported by the material screening mechanism 100 to the shaping mold mechanism 300 for shaping.

[0061] See also Figure 1 and Figure 2 The material transport mechanism 200 specifically includes two identical rectangular platforms 210, one end of each rectangular platform 210 is fixedly connected to a hopper 120, and each rectangular platform 210 is provided with a first slide groove 211. The metal powder injection molding parts to be shaped coming out of the spiral track 121 can slide into the shaping mold mechanism 300 through the first slide groove 211 for shaping.

[0062] In this way, by equipping each hopper 120 with a corresponding rectangular platform 210 for transporting materials, the material transport efficiency can be improved.

[0063] In addition, there is a second slide groove 212 on each rectangular table 210, and the second slide groove 212 is parallel to the first slide groove 211. The metal powder injection molding parts to be shaped coming out of the spiral track can also slide into the shaping mold mechanism 300 through the second slide groove 212, which can further improve the material transportation efficiency.

[0064] The number of the hopper 120, the rectangular platform 210, and the chutes on the rectangular platform 210 can be increased or decreased accordingly according to actual needs.

[0065] The height of one end of the rectangular table 210 connected to the hopper 120 is higher than the height of the other end. Since one end of the rectangular table 210 is fixedly connected to the hopper 120, regardless of whether the other end of the rectangular table 210 is fixed or not, when the hopper 120 vibrates, the rectangular table 210 will also vibrate slightly with the hopper 120, and the metal powder injection molding parts to be shaped coming out of the hopper 120 will first fall onto the rectangular table 210. When the rectangular table 210 vibrates, the metal powder injection molding parts to be shaped on the rectangular table 210 will flow into the first chute 211 or the second chute 212. Since the height of one end of the rectangular table 210 connected to the hopper 120 is higher than the height of the other end, it can directly slide on the first chute 211 or the second chute 212 and slide into the shaping mold mechanism 300.

[0066] In this way, the material transport mechanism 200 formed by the above structure does not need to be provided with a material belt driven by a motor, and the structure is very simple, thus saving costs.

[0067] See also Figure 1 and Figure 4In addition, a plurality of grating probes 700 may be provided on each rectangular table 210, and these grating probes 700 are respectively connected to the controller 600. The grating probes 700 may capture the position of the metal powder injection molded parts to be shaped on the first chute 211 or the second chute 212, and send the captured position information to the controller 600. When the position information sent by the grating probe 700 is incorrect, the controller 600 may sound an alarm through an alarm and stop the screening mechanism 100 from working. At this time, the worker will correct the position of the metal powder injection molded parts to be shaped on the first chute 211 or the second chute 212.

[0068] In this way, through the above-mentioned grating probe 700, the metal powder injection molded parts moving on the first slide groove 211 or the second slide groove 212 on each rectangular table 100 can be monitored in real time to prevent the metal powder injection molded parts from changing their position when moving on the first slide groove 211 or the second slide groove 212, thereby affecting subsequent shaping.

[0069] See also Figure 1 and Figure 2 The shaping mold mechanism 300 is used to shape the metal powder injection molding parts to be shaped delivered by the material conveying mechanism 200, and a width shaping structure and a plane shaping structure are provided on the shaping mold mechanism 300. The metal powder injection molding parts to be shaped delivered by the material conveying mechanism 200 can first be shaped by the width shaping structure, and then shaped by the plane shaping structure.

[0070] The shaping mold mechanism 300 specifically includes a workbench 310 , a shaping lower mold 320 and a shaping upper mold 330 .

[0071] The workbench 310 is located at one side of the base 110 . The shaping lower die 320 is arranged on the workbench 310 . The material transporting mechanism 200 can transport the metal powder injection molded parts to be shaped to the shaping lower die 320 .

[0072] The shaping upper mold 330 is located above the shaping lower mold 320, and is connected to an external hydraulic shaping machine. It is driven by the hydraulic shaping machine to move up and down above the shaping lower mold 320, thereby realizing mold closing and mold separation.

[0073] The hydraulic shaping machine can also be directly arranged on the workbench 310 .

[0074] A plurality of first shaping grooves 321 and a plurality of third shaping grooves 322 located in the same horizontal straight line are provided on the shaping lower die 320, and the third shaping grooves 322 are parallel to the first shaping grooves 321. A plurality of second shaping grooves and a plurality of fourth shaping grooves located in the same horizontal straight line are provided on the shaping upper die 330, and the fourth shaping grooves are parallel to the second shaping grooves. The number of the first shaping grooves 321, the number of the second shaping grooves, the number of the third shaping grooves 322 and the number of the fourth shaping grooves are the same.

[0075] Each second shaping groove is symmetrical with a first shaping groove 321, and each fourth shaping groove is symmetrical with a third shaping groove 322. When the shaping upper mold 330 and the shaping lower mold 320 are closed, each first shaping groove 321 contacts each second shaping groove to form a width shaping structure, and each fourth shaping groove contacts each third shaping groove 322 to form a plane shaping structure.

[0076] The number of the first shaping grooves 321, the number of the second shaping grooves, the number of the third shaping grooves 322 and the number of the fourth shaping grooves can all be four, which correspond to the four chutes respectively. The metal powder injection molding parts to be shaped conveyed by each chute can first slide into the corresponding first shaping groove 321, and then cooperate with the first shaping groove 321 to perform width shaping through the second shaping. After the width shaping, they can slide into the third shaping groove 322, and then cooperate with the third shaping groove 322 to perform plane shaping through the fourth shaping groove.

[0077] In addition, to facilitate the sliding of the metal powder injection molded parts, four slide rails 340 are correspondingly provided on the shaping lower die 320 , and each slide rail 340 is correspondingly provided with a first shaping groove 321 and a third shaping groove 322 .

[0078] The shaping mold mechanism 300 formed by the above structure can shape two batches of metal powder injection molded parts at the same time, and one batch is shaping the width while the other batch is shaping the plane, which greatly improves the work efficiency.

[0079] In addition, the present application does not make much change to the structure of the shaping upper mold 330 and the shaping lower mold 320. It can directly add a set of shaping grooves and a corresponding number of slide rails 340 to the existing shaping upper mold and shaping lower mold respectively. There is no need to redesign and manufacture the shaping upper mold 310 and the shaping lower mold 320, which saves costs.

[0080] In addition, the above-mentioned shaping mold mechanism 300 also includes a material limiting structure 350, which is used to pre-position the metal powder injection molding parts to be shaped delivered by the material transport mechanism 200, so that the material transfer mechanism 500 can accurately move the metal powder injection molding parts to be shaped into the corresponding shaping grooves on the shaping lower mold 330 according to the corresponding batches, thereby improving the shaping accuracy.

[0081] The material limiting structure 350 includes a telescopic cylinder 351 and a material receiving block 352. The telescopic cylinder 351 is arranged on the workbench 310. The material receiving block 352 is located between the shaping lower mold 320 and the rectangular table 210 and is connected to the telescopic cylinder 351. The telescopic cylinder 351 can drive the material receiving block 352 to rise and fall. Four material troughs 353 can be specifically arranged on the top of the material receiving block 352, and each material trough 353 corresponds to a slide groove.

[0082] When the telescopic cylinder 351 descends, the receiving block 352 can be driven to descend, and the metal powder injection molded parts transported from the rectangular table 210 can fall into the corresponding material trough 353 on the receiving block 352. When the telescopic cylinder 351 rises, the receiving block 352 can be pushed to rise. At this time, the receiving block 352 and the shaping lower mold 320 are located on the same horizontal plane, and the metal powder injection molded parts to be shaped on the rectangular table 210 are blocked, which is convenient for the material shifting mechanism 500 to shift the materials, and can also limit the metal powder injection molded parts to be shaped that are moved on the rectangular table 210, ensuring that the material shifting mechanism 500 can only move the limited metal powder injection molded parts each time, thereby improving work efficiency.

[0083] See also Figure 2 and Figure 3 The material-discharging mechanism 500 includes two groups of identical material-discharging components, which are arranged on the workbench 310 and symmetrically distributed on both sides of the shaping lower mold 320. Each group of material-discharging components includes a horizontal cylinder 510, a first connecting plate 520, a vertical cylinder 530, a second connecting plate 540 and a material-discharging plate 550.

[0084] The horizontal cylinder 510 is disposed on the workbench 310 , the first connecting plate 520 is movably disposed on the horizontal cylinder 510 , the vertical cylinder 530 is fixed on the first connecting plate 520 , the second connecting plate 540 is movably disposed on the vertical cylinder 530 , and the material stripping plate 550 is fixed on the second connecting plate 540 .

[0085] In this way, the horizontal cylinder 510 can drive the material stripper plate 550 to move horizontally, and the vertical cylinder 530 can drive the material stripper plate 550 to move vertically. The horizontal cylinder 510 and the vertical cylinder 530 work at the same time, which can drive the material stripper plate 550 to move vertically and horizontally at the same time.

[0086] Four parallel slots 560 are sequentially arranged on each material shifting plate 550, and the size of the slots 560 corresponds to the size of the metal powder injection molded parts. Moreover, before the material shifting plate 550 is not working, the slots 560 at the first position are in the same straight line with the material slot 353, the slots 560 at the second position are in the same straight line with the first shaping slot 321, and the slots 560 at the third position are in the same straight line with the third shaping slot 322.

[0087] In addition, four placement grooves 323 located in the same straight line are provided on the shaping lower mold 320, each placement groove 323 is parallel to a third shaping groove 322, and the slot 560 located at the first position on the material removal plate 550 is located in the same straight line as the placement groove 323.

[0088] In this way, when the material-moving mechanism 500 moves the material, the vertical cylinder 530 can be operated first to place the metal powder injection molded parts on the material trough 353 in the first card slot 560, and at the same time, the metal powder injection molded parts on the first shaping trough 321 are located in the second card slot 560, and at the same time, the metal powder injection molded parts on the third shaping trough 322 are located in the third card slot 560, and at the same time, the metal powder injection molded parts on the placement trough 323 will be located in the fourth card slot 560, and then the horizontal cylinder 510 will work, and the material-moving mechanism 500 can move the material. Plate 550 drives each metal powder injection molded part to move on the corresponding slide rail 340 on the shaping lower mold 320. At this time, the metal powder injection molded part originally on the material trough 353 will move to the first shaping trough 321, the metal powder injection molded part originally on the first shaping trough 321 will move to the third shaping trough 322, the metal powder injection molded part originally on the third shaping trough 322 will move to the placement trough 323, and the metal powder injection molded part originally on the placement trough 323 will move to the receiving plate 400.

[0089] In this way, each time the material shifting mechanism 500 works, the metal powder injection molded parts will move forward once, so that the shaping mold mechanism 300 can simultaneously load, width shape, plane shape and discharge different batches of metal powder injection molded parts.

[0090] In addition, the material dispensing mechanism 500 does not affect the shaping mold mechanism 300 in operation. When the shaping mold mechanism 300 is open, the material dispensing mechanism 500 operates. When the shaping mold mechanism is closed, the material dispensing mechanism 500 does not operate.

[0091] The receiving plate 400 is specifically in the shape of a slide. The shaped metal powder injection molded parts moved out by the stripping plate 550 can directly fall onto the receiving plate 400 and slide down into the corresponding recovery device.

[0092] See also Figure 4, a controller 600, which is respectively connected to the screening mechanism 100, the shaping mold mechanism 300 and the material shifting mechanism 500, and is used to control the operation of the screening mechanism 100, the shaping mold mechanism 300 and the material shifting mechanism 500.

[0093] The controller 600 is specifically connected to the vibration structure 111, the telescopic cylinder 351, the horizontal cylinder 510, the vertical cylinder 530, the hydraulic shaping machine and the grating probe 700, through which the automatic operation between the various mechanisms can be realized, further improving the work efficiency.

[0094] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
