[0001] The invention relates to the technical field of MIM parts processing, in particular to an automatic encapsulation and implantation mechanism for MIM parts. Background Art
[0002] MIM parts are a process for manufacturing metal parts, usually using powder metallurgy technology. The MIM process mixes metal powder with polymer powder and other additives to make a paste material that can be injection molded. The paste material is then injected into a mold and sintered at high temperature to form a dense metal part.
[0003] When manufacturing MIM parts, it is necessary to implant adhesive into metal powder and polymer powder to achieve mixing of various powders. Therefore, when the powders are mixed, an injection mechanism is needed to inject the adhesive into the mixer to mix it with the powders. However, at present, when the adhesive is implanted into the mixer to mix with the powders, the measured adhesive is generally directly put into the mixer and stirred and mixed with the powders at a certain temperature. However, the implantation of this adhesive will cause the adhesive to form a mass at the initial stage of stirring. The adhesive cannot fully contact with the mixed powder without stirring, resulting in poor mixing effect of the adhesive and the powder, and the problem that mixing requires a long time. Therefore, an automatic adhesive implantation mechanism for MIM parts is designed to solve the above-mentioned problems. Summary of the invention

DETAILED DESCRIPTION
[0018] The following will be described clearly and completely in conjunction with 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. Example
[0019] See also Figure 1 , Figure 2 , Figure 3 ,and Figure 7 This embodiment provides a MIM part automatic encapsulation and implantation mechanism, comprising a mixing box 1, a protective frame 2 is fixedly installed on the upper end of the mixing box 1, Figure 1 As shown, the protection frame 2 is used to protect the first gear 32 and the second gear 33 in the injection assembly 3. The injection assembly 3 is installed in the protection frame 2. The injection assembly 3 includes a servo motor 31, which is fixedly installed in the protection frame 2. The output end of the servo motor 31 is fixedly connected to the first gear 32, one side of the first gear 32 is meshed with the second gear 33, and the middle of the second gear 33 is penetrated and fixedly connected to the discharge pipe 34.
[0020] The servo motor 31 drives the No. 1 gear 32 to rotate, and the No. 1 gear 32 drives the No. 2 gear 33 to rotate, so that the No. 2 gear 33 drives the feed pipe 34 set in the middle to rotate with the center of the No. 2 gear 33 as the axis, so that the lower part of the feed pipe 34 rotates in the mixing box 1. At this time, the adhesive is transported from the upper end injection pipe to the transport pipe 11, and then transported from the transport pipe 11 to the feed pipe 34, and finally implanted from the injection nozzle into the mixed powder in the mixing box 1 for mixing.
[0021] The upper end of the feed pipe 34 passes through the second gear 33 and is rotatably connected to the transport pipe 11. The feed pipe 34 is L-shaped, and the lower end of the feed pipe 34 is fixedly connected to the injection nozzle. Figure 2 As shown, the upper end of the feed tube 34 is fixedly connected to the limit rod 12 in the mixing box 1, the upper end of the limit rod 12 is slidably connected to the limit frame 13, and the upper end of the limit frame 13 is fixedly connected to the inner end wall of the mixing box 1. The limit rod 12 will rotate with the feed tube 34, and maintain stable movement under the limit of the limit frame 13. The limit rod 12 and the limit frame 13 are used to protect the stability of the feed tube 34 during rotation, and prevent the feed tube 34 from shaking due to insufficient support force. Example
[0022] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 , further improvements were made on the basis of Example 1: A control assembly 4 is installed on the injection assembly 3. The control assembly 4 includes a mounting rod 41. The lower end of the mounting rod 41 is fixedly connected to the middle of the upper end of the first gear 32. The upper end of the mounting rod 41 is clamped with a threaded rod 42. The threaded rod 42 is a reciprocating screw rod. When the threaded rod 42 rotates, it can drive the moving ring 43 to reciprocate in the up and down directions. The threaded rod 42 is threadedly connected to one side of the moving ring 43 and fixedly connected to the connecting frame 44. Figure 4 The connecting frame 44 is fixedly connected to the support frame 45 on one side away from the movable ring 43, the opening of the support frame 45 faces downward, and a No. 1 spring 46 is fixedly connected inside the support frame 45, and the lower end of the No. 1 spring 46 is fixedly connected to a pressing plate 47, and a control switch 51 is provided at the lower end of the pressing plate 47, and the control switch 51 is installed on the power supply 5.
[0023] A power supply 5 is provided on one side of the control component 4, and a magnetic coil 7 is installed on the output end of the power supply 5. The magnetic coil 7 consists of a coil, an iron core and a mounting block, wherein one side of the mounting block is fixedly connected to the side wall of the mounting frame 6, and a transport pipe 11 is provided on one side of the magnetic coil 7. The transport pipe 11 is located on the upper part of the mixing box 1, and an injection pipe is fixedly installed on the upper end of the transport pipe 11. Adhesive is injected from the injection pipe and flows into the transport pipe 11, and the transport pipe 11 transports the adhesive to the discharge pipe 34.
[0024] The transport pipe 11 is fixedly connected to the fixed pipe 8 on the side away from the control component 4, and the fixed pipe 8 is fixedly connected to the No. 2 tension spring 81, and one side of the No. 2 tension spring 81 is fixedly connected to the blocking block 9, and the side of the blocking block 9 away from the No. 2 tension spring 81 is fixedly connected to the iron block 10, and the fixed pipe 8 and the transport pipe 11 are connected.
[0025] When the moving ring 43 drives the connecting frame 44 to descend, the connecting frame 44 drives the supporting frame 45 to descend, so that the supporting frame 45 drives the pressing plate 47 to descend and contact the control switch 51. After the control switch 51 is squeezed, the power supply 5 is started, so that the power supply 5 supplies power to the magnetic coil 7. After the magnetic coil 7 is energized, magnetism is generated. It is used to control the magnetic coil 7.
[0026] The power supply 5 is fixedly installed in the installation frame 6. One side of the installation frame 6 is fixedly connected to the side wall of the transport pipe 11. A through hole is opened at the upper end of the installation frame 6 for the pressing plate 47 to descend to contact the control switch 51 and start the control switch 51. Example
[0027] See also Figure 1 , Figure 2 , Figure 3 and Fig. 9 , further improvements were made on the basis of Example 2: When the feeding rate of the adhesive needs to be adjusted, the number of threads of the threaded rod 42 can be changed. Specifically, the threaded rod 42 can be replaced so that threaded rods 42 with different thread densities can be installed on the mounting rod 41. Therefore, a plug block 421 is fixedly connected to the lower end of the threaded rod 42, and slots are provided on both sides of the plug block 421. Push rods 411 are slidably connected to both sides of the upper part of the mounting rod 41, and a mounting groove is provided on the upper end of the mounting rod 41, and the plug block 421 is plugged into the mounting groove.
[0028] In order to maintain a stable connection, the push rod 411 and the mounting groove are also slidably connected, and the two sides of the push rod 411 are fixedly connected with a No. 1 tension spring 412, and the side of the No. 1 tension spring 412 away from the push rod 411 on the same side is fixedly connected to the side wall of the mounting rod 41.
[0029] When in use, the push rod 411 can be pulled to separate the push rod 411 from the slot and extend the No. 1 tension spring 412. Then the threaded rod 42 can be removed and replaced with a new threaded rod 42. The insert block 421 on the new threaded rod 42 can be inserted into the installation groove. Then the push rod 411 can be released so that the push rod 411 is driven by the No. 1 tension spring 412 to be reintegrated and the push rod 411 can be inserted into the slot.
[0030] When in use, start the servo motor 31, so that the servo motor 31 drives the No. 1 gear 32 to rotate, and the No. 1 gear 32 drives the No. 2 gear 33 to rotate, so that the No. 2 gear 33 drives the discharge pipe 34 set in the middle to rotate with the center of the No. 2 gear 33 as the axis, so that the lower part of the discharge pipe 34 rotates in the mixing box 1. At this time, the adhesive is transported from the upper end injection pipe to the transport pipe 11, and then transported from the transport pipe 11 to the discharge pipe 34, and finally implanted from the injection nozzle into the mixed powder in the mixing box 1 for mixing.
[0031] The feeding pipe 34 drives the injection nozzle to rotate at a uniform speed in the mixing box 1, so that the adhesive sprayed from the injection nozzle can evenly fall into the mixed powder in the mixing box 1, thereby avoiding reducing the contact area with the powder after agglomeration and avoiding the situation where a long mixing time is required.
[0032] When the No. 1 gear 312 rotates, the No. 1 gear 32 drives the mounting rod 41 to rotate, so that the mounting rod 41 drives the threaded rod 42 to rotate. The threaded rod 42 is a reciprocating screw rod. The rotation of the threaded rod 42 drives the moving ring 43 to reciprocate in the up and down directions. When the moving ring 43 rises, it drives the connecting frame 44 to move, so that the connecting frame 44 drives the supporting frame 45 to rise, and the supporting frame 45 drives the No. 1 spring 46 to rise, and the pressing plate 47 set at the lower end rises and moves away from the control switch 51. Therefore, the control switch 51 is in an open and closed state, so that the power supply 5 does not energize the magnetic coil 7.
[0033] When the movable ring 43 drives the connecting frame 44 to descend, the connecting frame 44 drives the supporting frame 45 to descend, so that the supporting frame 45 drives the pressing plate 47 to descend and contact with the control switch 51. After the control switch 51 is squeezed, the power supply 5 is started, so that the power supply 5 supplies power to the magnetic coil 7. After the magnetic coil 7 is energized, it will generate magnetism and adsorb the iron block 10 located on one side in the fixed tube 8, so that the iron block 10 moves and drives the blocking block 9 to move. After the blocking block 9 moves, it blocks the transport tube 11, so that the adhesive in the transport tube 11 cannot continue to be discharged, thereby realizing the function of controlling the discharge of the adhesive in the transport tube 11. When the power supply 5 no longer provides power to the magnetic coil 7, the No. 2 tension spring 81 in the fixed tube 8 pulls the blocking block 9 to move and restore, so that the blocking block 9 no longer blocks the transport tube 11, and the adhesive in the transport tube 11 can continue to be discharged.
[0034] The method of intermittently controlling the feeding of adhesive can avoid the problem of uneven mixing caused by continuous feeding of adhesive, which will lead to too much adhesive being put in at one time. The mixed powder and adhesive can always be fully stirred, which is conducive to the continuous operation of automatic encapsulation of MIM parts.
[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
