Description

Technical Field

[0001] This invention relates to the field of magnetic tile production equipment technology, and in particular to a multi-cavity synchronous material injection control device for magnetic tile molds. Background Technology

[0002] Magnet tiles are arc-shaped permanent magnet components specifically designed for rotating electric motors, typically made of hard magnetic materials such as ferrite, neodymium iron boron, or AlNiCo. Their core principle is to create a directional magnetic field in the stator or rotor of the motor through a tile-like geometry. When this magnetic field interacts with a energized coil, it generates a Lorentz force, driving the mechanical motion. Compared to traditional electromagnets, magnet tiles offer advantages such as no excitation current required, high energy conversion efficiency, and small size, while also meeting requirements for high-temperature stability and corrosion resistance. Modern magnet tiles optimize the magnetic field distribution through radial magnetization and multi-pole magnetization techniques, and enhance durability with epoxy resin coatings or nickel plating. They are widely used in new energy vehicle drive motors, air conditioning compressors, industrial servo motors, and other fields, serving as key components for improving motor power density and energy efficiency.

[0003] The production of magnetic tiles mainly involves four key steps: first, ferrite or rare earth raw materials are mixed and ground in a specific ratio; next, the material is poured into the magnetic tile mold to form the tile; then, it is sintered at a high temperature of 1200-1300℃ to form a dense crystalline structure; finally, grinding, surface treatment, and magnetization testing are performed. Traditional injection equipment can only inject material into one magnetic tile mold at a time. This results in low injection efficiency for mass production, thus limiting the overall production efficiency of magnetic tiles. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a multi-cavity synchronous injection control device for magnetic tile molds. The specific technical solution is as follows:

[0005] A multi-cavity synchronous injection control device for magnetic tile molds includes a worktable, a multi-cavity injection mechanism on the top of the worktable, and a mold support mechanism on the top of the worktable.

[0006] The multi-cavity injection mechanism includes a support leg, which is fixedly installed on the top of the workbench. A material distribution box is fixedly installed at the end of the support leg away from the workbench. A branch pipe is fixedly connected to the bottom of the material distribution box, and the number of branch pipes is set to six. A square tube is fixedly connected to the back of the material distribution box, and a connecting fitting is fixedly connected to the back of the square tube. A through hole is opened at the bottom of the material distribution box, and an electric cylinder is fixedly installed at the top of the material distribution box.

[0007] As an improvement to the above technical solution, the telescopic end of the electric cylinder extends into the inner cavity of the dispensing box and is fixedly connected to a connecting frame, and an annular valve is fixedly installed at the bottom of the connecting frame.

[0008] As an improvement to the above technical solution, a stainless steel mesh plate is fixedly installed on the inner wall of the square tube, and an internal threaded hole is opened at the bottom of the square tube, with a cover plate threaded to the bottom of the internal threaded hole.

[0009] As an improvement to the above technical solution, the mold support mechanism includes a rubber vibration isolation foot, which is fixedly installed on the top of the workbench. A base plate is fixedly installed on the top of the rubber vibration isolation foot, a support column is fixedly installed on the top of the base plate, a receiving plate is fixedly installed on the top of the support column, and a vibration motor is fixedly installed on the top of the base plate.

[0010] As an improvement to the above technical solution, the top of the receiving plate is detachably connected to a movable seat, the top of the movable seat is fixedly installed with a magnetic tile mold, and the top of the movable seat is fixedly installed with a handle.

[0011] As an improvement to the above technical solution, a protrusion is fixedly connected to the top of the receiving plate, and a bolt is threadedly connected to the top of the protrusion. A limit member is movably sleeved on the outer wall of the bolt.

[0012] The beneficial effects of this invention are:

[0013] 1. By connecting pipe fittings (connecting to the hopper) → square pipe (conveying raw materials) → material distribution box (temporary storage and diversion) → electric cylinder + connecting frame + ring valve (controlling the opening and closing of the through hole) → branch pipe (diverting to multiple mold cavities), the raw materials can be conveyed, temporarily stored and controlled from the hopper and then simultaneously distributed to 6 branch pipes, realizing the simultaneous injection of materials into multiple magnetic tile mold cavities. This solves the problem of low single-cavity injection efficiency of traditional equipment, significantly improves injection efficiency, and thus improves the overall production efficiency of magnetic tiles.

[0014] 2. When raw materials pass through the square tube, the stainless steel mesh plate can intercept large particles of impurities, preventing them from entering the mold cavity and affecting the quality of the magnetic tiles. When impurities accumulate, they can be quickly cleaned by disassembling the cover plate (using the threaded connection of the internal threaded hole). This ensures the purity of the raw materials, facilitates maintenance, and indirectly improves the pass rate of magnetic tile production.

[0015] 3. The vibration is transmitted via a vibratory motor (providing vibration force) → base plate + support column (transmitting vibration) → receiving plate + movable seat (driving the mold) → magnetic tile mold (compacting the raw material through vibration); rubber vibration isolation feet (isolating vibration). The vibration force generated by the vibratory motor is transmitted through the base plate and support column to the receiving plate, causing the magnetic tile mold to vibrate. This eliminates gaps in the raw material within the mold cavity, resulting in a tighter filling. Simultaneously, the rubber vibration isolation feet reduce the transmission of vibration to the worktable, preventing overall equipment resonance from affecting stability. This combined effect improves the compactness of the filling and ensures the stability of the equipment operation, further increasing the yield rate of magnetic tile production.

[0016] 4. After the movable seat is positioned by the protruding block, the limiting component can be quickly locked by bolts to ensure the stability of the magnetic tile mold during injection and vibration. The handle facilitates the movement of the movable seat, and the detachable structure allows for easy replacement of magnetic tile molds of different specifications. This not only ensures the stability of mold installation but also improves the equipment's adaptability to different production needs and facilitates operation. This invention optimizes the magnetic tile production process in multiple dimensions, including injection efficiency, raw material quality, molding effect, and ease of operation, ultimately achieving comprehensive benefits such as increased production efficiency, higher product qualification rate, and enhanced equipment adaptability.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] Example

[0026] For the multi-cavity synchronous injection control device of magnetic tile mold, please refer to... Figures 1-6It includes a workbench 1, a multi-cavity injection mechanism 2 is provided on the top of the workbench 1, and a mold support mechanism 3 is provided on the top of the workbench 1.

[0027] The multi-cavity injection mechanism 2 includes a support leg 21, which is fixedly installed on the top of the worktable 1. A material distribution box 22 is fixedly installed at the end of the support leg 21 away from the worktable 1. A branch pipe 23 is fixedly connected to the bottom of the material distribution box 22. The number of branch pipes 23 is set to six. A square tube 24 is fixedly connected to the back of the material distribution box 22. A connecting pipe 25 is fixedly connected to the back of the square tube 24. A through hole 221 is opened at the bottom of the material distribution box 22. An electric cylinder 222 is fixedly installed at the top of the material distribution box 22. The output end of the hopper is pre-connected to the end of the connecting pipe 25. After the material is dispensed, the raw material is added into the hopper. The hopper is connected to the inner cavity of the connecting pipe 25. The raw material will pass through the connecting pipe 25 and the square tube 24 into the inner cavity of the material distribution box 22, and then pass through the through hole 221 into the interior of the branch pipe 23. The branch pipe 23 can introduce the raw material into multiple mold cavities, thus realizing the function of synchronous injection and improving efficiency.

[0028] like Figure 2 As shown, the telescopic end of the electric cylinder 222 extends into the inner cavity of the material distribution box 22 and is fixedly connected to the connecting frame 223. An annular valve 224 is fixedly installed at the bottom of the connecting frame 223. In the initial state, the bottom of the annular valve 224 moves against the bottom of the inner wall of the material distribution box 22, thereby closing the through hole 221 and blocking the material discharge. If material discharge is required, the electric cylinder 222 is controlled to retract, and the annular valve 224 is moved upward through the transmission of the connecting frame 223, adjusting the through hole 221 to the open state, and then the material discharge can be carried out.

[0029] like Figure 3 As shown, a stainless steel mesh plate 241 is fixedly installed on the inner wall of the square tube 24. The bottom of the square tube 24 has an internal threaded hole 242, and a cover plate 243 is threaded to the bottom of the internal threaded hole 242. The mesh diameter of the stainless steel mesh plate 241 is 10 mm, which facilitates the passage of raw materials and can intercept large particles of impurities, thus avoiding the problem of large particles of impurities affecting the quality of the magnetic tiles. During maintenance, the cover plate 243 is rotated out from the bottom of the internal threaded hole 242, and the impurities filtered by the stainless steel mesh plate 241 can be cleaned.

[0030] like Figure 4As shown, the mold support mechanism 3 includes a rubber vibration isolation foot 31, which is fixedly installed on the top of the workbench 1. A base plate 32 is fixedly installed on the top of the rubber vibration isolation foot 31, a support column 33 is fixedly installed on the top of the base plate 32, a receiving plate 34 is fixedly installed on the top of the support column 33, and a vibration motor 35 is fixedly installed on the top of the base plate 32. During the injection process, the vibration motor 35 is controlled to work, which can drive the receiving plate 34 to vibrate as a whole, thereby causing the magnetic tile mold 37 to vibrate, so as to eliminate the gap inside the magnetic tile mold 37, improve the tightness of the injection, and increase the production qualification rate of the magnetic tile. Through the design of the rubber vibration isolation foot 31, the amplitude of the vibration generated by the vibration motor 35 transmitted to the workbench 1 can be reduced.

[0031] like Figure 5 , Figure 6 As shown, a movable seat 36 is detachably connected to the top of the receiving plate 34. A magnetic tile mold 37 is fixedly installed on the top of the movable seat 36. A handle is fixedly installed on the top of the movable seat 36. A protrusion 341 is fixedly connected to the top of the receiving plate 34. A bolt 342 is threadedly connected to the top of the protrusion 341. A limiting member 343 is movably sleeved on the outer wall of the bolt 342. When installing the magnetic tile mold 37, the movable seat 36 is fitted into the outer wall of the protrusion 341. Then, the limiting member 343 is rotated so that it rests on the top of the movable seat 36. Then, the bolt 342 is tightened to fix the position of the limiting member 343, thus completing the fixing of the movable seat 36 for user convenience.

[0032] Working principle: In use, first install the magnetic tile mold 37, fit the movable seat 36 into the outer wall of the protrusion 341, then rotate the limiting member 343 so that the limiting member 343 rests on the top of the movable seat 36, and then tighten the bolt 342 to adjust the position of the limiting member 343. The output end of the hopper is pre-connected to the end of the connecting pipe 25. After the material is dispensed, the raw material is added into the hopper, and the electric cylinder 222 is controlled to retract. Through the transmission of the connecting frame 223, the annular valve 224 is moved upward, adjusting the through hole 22. When 1 is in the open state, material discharge can begin. The hopper is connected to the inner cavity of the connecting pipe 25. The raw material passes through the connecting pipe 25 and the square tube 24 into the inner cavity of the distribution box 22, and then passes through the through hole 221 into the interior of the branch pipe 23. The branch pipe 23 can introduce the raw material into multiple mold cavities, thus realizing the function of synchronous material injection. During the material injection process, the vibration motor 35 is controlled to work, which can drive the entire receiving plate 34 to vibrate, thereby causing the magnetic tile mold 37 to vibrate, so as to eliminate the gap inside the magnetic tile mold 37 and improve the production quality.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
