Description

Technical Field

[0001] This utility model belongs to the field of stainless steel condenser parts manufacturing technology, specifically, it relates to a powder feeding device for metal injection molding of stainless steel condenser parts. Background Technology

[0002] In the manufacturing of stainless steel condenser parts, metal injection molding technology has been widely used due to its ability to produce high-precision, complex-shaped parts. In the metal injection molding process, the powder feeding device is one of the key pieces of equipment, and its performance directly affects the quality of the parts and the production efficiency.

[0003] Traditional metal injection molding powder feeding devices for stainless steel condenser parts mostly employ a one-piece structure for the mixing cylinder. While this structure can meet basic functional requirements such as mixing and feeding of metal powder and binder during normal production, it reveals serious drawbacks when cleaning the interior after production. Because the cylinder cannot be disassembled, cleaning personnel can only clean the interior through limited openings, resulting in extremely confined operating space. This makes it difficult to thoroughly clean corners and hidden areas. Residual metal powder and binder not only affect the purity and quality of feed in the next production run, thus impacting the performance and quality of the stainless steel condenser parts, but may also cause corrosion and damage to internal components over time, shortening the equipment's lifespan. Therefore, we propose a metal injection molding powder feeding device for stainless steel condenser parts. Utility Model Content

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A powder feeding device for metal injection molding of stainless steel condenser parts includes a top plate, a bottom plate, and two semi-cylinders (one and two). Support plates are installed near both sides of the top and bottom plates. Semi-cylinders one and two are engaged between the top and bottom plates. Each semi-cylinder has an inner groove, in which the support plates are movably embedded. Positioning blocks are installed on the inner walls of the grooves. Positioning holes are formed on the support plates, and the positioning blocks are inserted into the positioning holes. A connecting assembly is provided between semi-cylinders one and two. A feeding pipe is connected to the bottom end of the bottom plate. A rotating cylinder runs through the top plate and is rotatably connected to the top plate via bearings.

A support frame 11 is installed at the top of the top plate 1, and a motor 17 is installed at the top of the support frame 11. The rotating drum 12 is connected to the motor 17 via transmission. Multiple stirring plates 19 are fixedly installed on the outer wall of the rotating drum 12. A second motor 18 is installed at the top of the support frame 11. A long rotating shaft 14 is installed at the output end of the second motor 18. The long rotating shaft 14 passes through the top of the support frame 11 and the rotating drum 12 and extends into the feed pipe 20. The long rotating shaft 14 is rotatably connected to the support frame 11 via bearings. Spiral conveying blades 21 are fixedly installed on the outer wall of the long rotating shaft 14 inside the feed pipe 20.

[0018] Furthermore, a short shaft 16 is installed at the output end of motor 17. The short shaft 16 passes through the top of the support frame 11 and is rotatably connected to the support frame 11 through a bearing. A gear 2 15 is installed at the bottom of the short shaft 16. A gear 13 is fixedly sleeved on the outer wall of the rotating drum 12 near the top. The gear 13 meshes with the gear 2 15.

[0019] By setting gear 13 and gear 2 15, motor 17 can drive gear 2 15 to rotate via short shaft 16, and gear 2 15 can drive gear 13 to rotate, thereby enabling gear 13 to drive drum 12 to rotate.

[0020] Furthermore, sealing arc plates 7 are installed at the top and bottom of both half-cylinder 1 4 and half-cylinder 2 6. Sealing ring grooves 8 are opened on the outer walls of the bottom of the top plate 1 and the top of the bottom plate 2, and the sealing arc plates 7 are engaged in the sealing ring grooves 8.

[0021] By setting the sealing arc plate 7 and the sealing ring groove 8, the sealing performance between the first half cylinder 4 and the second half cylinder 6 and the top plate 1 and the bottom plate 2 can be increased.

[0022] Furthermore, there are two positioning blocks 9 in the groove 5, and the positioning blocks 9 are adapted to the positioning holes 10.

[0023] By setting the positioning block 9 and the positioning hole 10, the half-cylinder 4 and the half-cylinder 2 6 can be limited and fixed, thereby improving the stability of the half-cylinder 4 and the half-cylinder 2 6 during use.

[0024] Furthermore, the connecting components include connecting plate 1 22, connecting plate 23, and U-shaped clamping plate 30. Connecting plate 1 22 and connecting plate 23 are respectively installed on the outer walls of half cylinder 1 4 and half cylinder 2 6. The outer walls of connecting plate 1 22 and connecting plate 23 are provided with clamping groove 2 31. The U-shaped clamping plate 30 is clamped in the clamping groove 2 31. One end of connecting plate 1 22 and connecting plate 23 is hinged with an L-shaped clamping plate 25. The U-shaped clamping plate 30 is provided with clamping groove 1 29 on both sides.

[0025] Furthermore, both connecting plate 1 22 and connecting plate 23 have a rotating groove 24 at one end, a connecting shaft 26 is installed on the inner wall of the rotating groove 24, and an L-shaped clamping plate 25 has a shaft hole 27 at one end. The connecting shaft 26 moves through the shaft hole 27, and a torsion spring 28 is connected between the outer wall of the connecting shaft 26 and the inner wall of the shaft hole 27.

[0026] The L-shaped retaining plate 25 can be automatically reset by setting a torsion spring 28.

[0027] Furthermore, the L-shaped card plate 25 is adapted to the card slot 29, and the U-shaped card plate 30 is adapted to the card slot 31.

[0028] Furthermore, four mounting blocks 32 are installed on the outer wall of the base plate 2 near the bottom end, and mounting holes are opened on the mounting blocks 32. A feed pipe 33 is connected to the top of the top plate 1.

[0029] The implementation principle of the metal injection molding powder feeding device for stainless steel condenser parts is as follows: Metal powder and binder are added to the cylinder body consisting of half-cylinder 4 and half-cylinder 6 through the feed pipe. Then, motor 17 is started, which drives short shaft 16 to rotate. Short shaft 16 drives gear 2 15 to rotate. Gear 2 15 drives gear 1 13 to rotate. Gear 1 13 drives rotating cylinder 12 to rotate. Rotating cylinder 12 drives stirring plate 19 to rotate in the cylinder body, so that stirring plate 19 stirs and mixes metal powder and binder. When the two are evenly mixed, motor 2 18 is started, which drives long shaft 14 to rotate. Long shaft 14 drives spiral conveying blade 21 to rotate, so that spiral conveying blade 21 conveys the evenly mixed feed material inside the cylinder to the injection molding machine through feed pipe 20. Then, injection molding is performed by the injection molding machine. When the device is finished and its interior needs cleaning, the L-shaped clamping plate 25 can be rotated outwards to twist the torsion spring 28, causing the L-shaped clamping plate 25 to disengage from the first clamping slot 29. This removes the L-shaped clamping plate 25 from limiting the U-shaped clamping plate 30. Then, the U-shaped clamping plate 30 is moved upwards to disengage from the second clamping slot 31, removing the U-shaped clamping plate 30 from limiting the connection between the first connecting plate 22 and the second connecting plate 23. At this point, moving the first half-cylinder 4 and the second half-cylinder 6 to the sides will separate them from each other. The mixing cylinder is separated from the first half-cylinder 4, the second half-cylinder 6, the top plate 1, and the bottom plate 2, exposing the stirring plate 19 between the top plate 1 and the bottom plate 2. This greatly increases the operating space for cleaning personnel. Through the above structure, the mixing cylinder is set as a split structure of the first half-cylinder 4, the second half-cylinder 6, the top plate 1, and the bottom plate 2. When it is necessary to clean the inside of the cylinder, it can be separated, which greatly increases the operating space for cleaning personnel, reduces the difficulty of cleaning, and thus improves the efficiency of cleaning. The structure is simple and highly practical.
