Abstract

This utility model relates to an anti-deflection guide structure for magnetic tile molds, including a base, a lower mold, and an upper mold. The lower mold is detachably connected to the top of the base. A vertical constraint structure is provided on the top of the base, and a docking mechanism is provided on the base and the vertical constraint structure. The vertical constraint structure includes a vertical guide column and a lifting plate. The vertical guide column is fixed to the top of the base. Through the overall design of the vertical constraint structure, during the lifting and lowering process of the upper mold, the lifting plate slides on the outer wall of the vertical guide column, forming a rigid constraint on the upper mold in the vertical direction, ensuring the coaxiality of the lower and upper molds and achieving the anti-deflection function. Furthermore, through the overall design of the docking mechanism, when the lower and upper molds are closed, the joint is inserted into the inner cavity of the docking hole, further enhancing the spatial positioning accuracy when the molds are closed, reducing the probability of misalignment of the lower and upper molds, and ensuring the production quality of the magnetic tiles.

Description

Technical Field

[0001] This utility model relates to the field of magnetic tile mold technology, and in particular to an anti-deflection guide structure for magnetic tile molds. Background Technology

[0002] Magnet tiles are a key functional material widely used in permanent magnet motors. They are mainly made of ferrite or rare-earth permanent magnet materials through powder metallurgy pressing and sintering. They are typically arc-shaped tiles with precision-ground surfaces to achieve specific dimensional accuracy. The inner arc surface fits tightly against the motor rotor core, while the outer arc surface forms a uniform air gap magnetic field. After magnetization, the magnet tiles have a stable north-south pole distribution, allowing them to interact with the alternating magnetic field generated by the stator windings, thus converting electrical energy into mechanical energy. As a core component of permanent magnet motors, the magnetic properties and temperature stability of magnet tiles directly affect the motor's efficiency, torque, and lifespan. They are commonly found in automotive starter motors, power tools, household appliance motors, and industrial servo systems. Their manufacturing process requires strict control of material ratios, orientation magnetic field strength, and sintering processes to ensure high magnetic energy product and resistance to demagnetization. Modern magnet tiles also utilize nickel plating or epoxy coatings to enhance corrosion resistance.

[0003] The production of magnetic tiles involves the use of molds. Traditional mold structures rely solely on a single-axis lifting device to move the upper mold up and down. When the molds are closed, slight misalignment can easily occur between the upper and lower molds, leading to dimensional deviations in the subsequently produced magnetic tiles and consequently reducing the yield rate of the magnetic tiles. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing an anti-deflection guiding structure for magnetic tile molds. The specific technical solution is as follows:

[0005] The magnetic tile mold anti-deflection guide structure includes a base, a lower mold and an upper mold. The lower mold is detachably connected to the top of the base. A vertical constraint structure is provided on the top of the base. A docking mechanism is provided on the base and the vertical constraint structure.

[0006] The vertical constraint structure includes a vertical guide column and a lifting plate. The vertical guide column is fixed to the top of the base. A connecting seat is fixedly installed on the top of the lifting plate. An embedded block is fixedly installed on the inner wall of the lifting plate. A groove is formed on the inner wall of the embedded block. A roller is rotatably connected to the inner wall of the groove. The outer wall of the roller is movably connected to the outer wall of the vertical guide column. The upper mold is detachably connected to the bottom of the lifting plate.

[0007] As an improvement to the above technical solution, a triangular support is fixedly installed on the side of the vertical guide column, the triangular support is fixedly installed on the top of the base, and a connecting rod is fixedly connected to the outer wall of the vertical guide column.

[0008] As an improvement to the above technical solution, the vertical constraint structure also includes columns, which are fixedly installed on the top of the base. The number of columns is set to two, and an X-shaped reinforcement is fixedly connected between the adjacent sides of the two columns. An extension arm is fixedly connected to the front of the column.

[0009] As an improvement to the above technical solution, the extendable arm is fixedly connected to the top of the vertical guide column, and a reinforcing diagonal brace is fixedly installed on the front of the column, with the bottom of the reinforcing diagonal brace fixedly connected to the top of the extendable arm.

[0010] As an improvement to the above technical solution, the docking mechanism includes a support leg, which is fixedly installed on the top of the base. A receiving block is fixedly installed on the top of the support leg. A round through hole is opened on the top of the receiving block, and a square through hole is opened on the side of the receiving block.

[0011] As an improvement to the above technical solution, a fixed docking block is fixedly installed on the top of the receiving block, and a docking hole is opened on the top of the fixed docking block.

[0012] As an improvement to the above technical solution, the docking mechanism further includes a side plate, which is fixedly connected to the side of the lifting plate, and a docking joint is fixedly connected to the bottom of the side plate.

[0013] The beneficial effects of this utility model are:

[0014] Through the overall design of the vertical constraint structure, during the lifting and lowering process of the upper mold, the lifting plate slides on the outer wall of the vertical guide column, forming a rigid constraint on the upper mold in the vertical direction, ensuring the coaxiality of the lower mold and the upper mold, and realizing the function of preventing deflection.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 of the present utility model and are not intended to limit the present utility model.

[0022] Example

[0023] For the anti-deflection guide structure of the magnetic tile mold, please refer to... Figures 1-5 It includes a base 1, a lower mold 11 and an upper mold 12. The lower mold 11 is detachably connected to the top of the base 1. A vertical constraint structure 2 is provided on the top of the base 1. A docking mechanism 3 is provided on the base 1 and the vertical constraint structure 2.

[0024] The vertical constraint structure 2 includes a vertical guide column 21 and a lifting plate 22. The vertical guide column 21 is fixed to the top of the base 1. A connecting seat 23 is fixedly installed on the top of the lifting plate 22. An embedded block 221 is fixedly installed on the inner wall of the lifting plate 22. A groove 222 is formed on the inner wall of the embedded block 221. A roller 223 is rotatably connected to the inner wall of the groove 222. The outer wall of the roller 223 is movably connected to the outer wall of the vertical guide column 21. The upper mold 12 is detachably connected to the bottom of the lifting plate 22. The telescopic end of the lifting device can be connected to the connecting seat 23. During operation, the lifting plate 22 can be raised and lowered, driving the upper mold 12 to perform mold opening or closing. During the raising and lowering of the lifting plate 22, the roller 223 will roll on the outer wall of the vertical guide column 21, improving the smoothness of the lifting plate 22's raising and lowering. The upper mold 12 is installed on the lifting plate 22 with bolts. Users can replace the upper mold 12 with different specifications. By sliding the lifting plate 22 as a whole on the outer wall of the vertical guide column 21, a rigid constraint is formed on the upper mold 12 in the vertical direction, ensuring the coaxiality of the lower mold 11 and the upper mold 12, and realizing the function of preventing deflection.

[0025] like Figure 2As shown, a triangular support 24 is fixedly installed on the side of the vertical guide column 21. The triangular support 24 is fixedly installed on the top of the base 1. A connecting rod 25 is fixedly connected to the outer wall of the vertical guide column 21. The design of the triangular support 24 can improve the stability of the vertical guide column 21 connected to the top of the base 1. The design of the connecting rod 25 can connect the two vertical guide columns 21 in the front and rear directions to implement the reinforcement function.

[0026] like Figure 4 As shown, the vertical constraint structure 2 also includes columns 26, which are fixedly installed on the top of the base 1. There are two columns 26, and an X-shaped reinforcement member 261 is fixedly connected between the adjacent sides of the two columns 26. An extension arm 262 is fixedly connected to the front of the column 26, and the extension arm 262 is fixedly connected to the top of the vertical guide column 21. A reinforcing diagonal rod 263 is fixedly installed on the front of the column 26, and the bottom of the reinforcing diagonal rod 263 is fixedly connected to the top of the extension arm 262. Through the design of the extension arm 262, the two vertical guide columns 21 in the front-back direction can be connected from above to implement the reinforcement function. The column 26 reinforces the vertical guide column 21 with the extension arm 262. Through the design of the reinforcing diagonal rod 263, the connection stability between the extension arm 262 and the column 26 is improved. Through the design of the X-shaped reinforcement member 261, the two columns 26 can be connected to further increase the stability.

[0027] like Figure 5 As shown, the docking mechanism 3 includes a support leg 31, which is fixedly installed on the top of the base 1. A receiving block 32 is fixedly installed on the top of the support leg 31. A round through hole 33 is opened on the top of the receiving block 32, and a square through hole 34 is opened on the side of the receiving block 32. A fixed docking block 35 is fixedly installed on the top of the receiving block 32, and a docking hole 36 is opened on the top of the fixed docking block 35. The docking mechanism 3 also includes a side plate 37, which is fixedly connected to the side of the lifting plate 22. A connecting joint 38 is fixedly connected to the bottom of the side plate 37. The lower mold 11 When the upper mold 12 is closed, the connector 38 will be inserted into the inner cavity of the mating hole 36, further enhancing the spatial positioning accuracy when the mold is closed, reducing the probability of misalignment between the lower mold 11 and the upper mold 12, and ensuring the production quality of the magnetic tile. The bottom of the connector 38 is designed in the shape of a frustum, which facilitates smooth insertion into the interior of the mating hole 36. The interiors of the mating hole 36, the round through hole 33, and the square through hole 34 are connected in sequence. The debris inside the mating hole 36 will be discharged through the round through hole 33 and the square through hole 34, avoiding the problem that debris accumulation can easily affect the accuracy of the mating.

[0028] Working principle: When in use, the telescopic end of the lifting device is connected to the connecting seat 23. When the lifting device is working, it can drive the lifting plate 22 to rise and fall, driving the upper mold 12 to perform mold opening or closing. When closing the mold, the lifting plate 22 slides downward on the outer wall of the vertical guide column 21, forming a rigid constraint on the upper mold 12 in the vertical direction, ensuring the coaxiality of the lower mold 11 and the upper mold 12. When the mold is about to close, the connector 38 will be inserted into the inner cavity of the docking hole 36, further enhancing the spatial positioning accuracy when the mold is closed, reducing the probability of the lower mold 11 and the upper mold 12 offsetting, and realizing the function of high-precision guidance.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
