[0002] At present, an iron core is a core component made of iron or iron alloy material and is widely applied to electrical equipment such as transformers, motors and generators. The main function of the iron core is to provide an efficient magnetic path, to enhance the magnetic field generated by the current and to reduce energy loss. The iron core usually adopts high magnetic permeability materials such as silicon steel sheets or iron powder to reduce eddy current loss and hysteresis loss.

[0003] In the process of processing the iron core, low-carbon silicon steel strips are selected, and surface treatment and coating are performed to enhance the magnetic property and insulation. Then, the steel strips are cut into small pieces and stacked into a multi-layer structure according to a specific direction to reduce eddy current loss. Then, the structure is ensured to be stable through pressing and fixing, and annealing treatment is performed to improve the magnetic property.

[0004] The existing Chinese patent with the publication number CN202523500U discloses an iron core, which aims to provide an iron core with good stability and not easy to deform. The technical solution points of the iron core are as follows: the iron core body includes a plurality of iron core pieces stacked together, the first iron core piece of the iron core body is provided with a rectangular through hole, the remaining iron core pieces are provided with rectangular half holes matched with the rectangular through hole, and the remaining iron core pieces are placed in the rectangular through hole after being stacked through the rectangular half holes.

[0005] According to the related technology in the above, the thickness error of the plurality of single iron core pieces is further enlarged after the plurality of iron core pieces are stacked together, and the iron core may have the problems of flash defects and different product heights in the process of injection molding of the iron core. UTILITY MODEL CONTENT

[0006] The utility model solves the technical problem that the thickness error of the plurality of single iron core pieces is further enlarged after the plurality of iron core pieces are stacked together, and the iron core may have the problems of flash defects and different product heights in the process of injection molding of the iron core.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical scheme.

[0008] A height adjustment mechanism for iron core injection molding includes: a fixed base for supporting a height adjustment component; a push rod assembly mounted on the fixed base for lifting the iron core; and an adjustment component mounted on one side of the fixed base for lifting the fixed base.

[0009] Furthermore, the adjustment assembly includes a hydraulic cylinder and an adjustment rod. The hydraulic cylinder is mounted on one side of the fixed base, and the adjustment rod is mounted on one end of the hydraulic cylinder, with the other end extending towards the side closer to the fixed base.

[0010] Furthermore, the fixed base is provided with an adjusting block, and the fixed base is mounted on the adjusting block.

[0011] Furthermore, a first guide slope is formed on the adjusting block, and a second guide slope is formed on the adjusting rod, with the second guide slope facing towards the side closer to the adjusting block.

[0012] Furthermore, the push rod assembly includes a first push rod and a second push rod, the first push rod is mounted on the fixed base, and a plurality of second push rods are arranged at intervals around the first push rod.

[0013] Furthermore, the ends of the first and second push rods away from the adjusting seat form a support surface, and the support surfaces are arranged in parallel intervals.

[0014] Furthermore, a groove is formed at the end of the adjusting rod away from the adjusting block, and a connecting rod is provided on the oil cylinder. One end of the connecting rod is connected to the oil cylinder, and the other end passes into the groove. A locking block is provided at the end of the connecting rod that passes into the groove, and the locking block engages with the groove.

[0015] In summary, this application includes at least one of the following beneficial technical effects of a height adjustment mechanism for iron core injection molding:

[0016] In use, iron chips are stacked in the cavity of the injection molded part, and then the ejector pins support the iron chips. The adjustment component supports the stacked iron chips through the ejector pins, and then the height of the iron chips is adjusted by the adjustment component. This ensures that the height of several finished iron cores is uniform after injection molding during the production process, preventing the thickness error from being further amplified when the iron chips are stacked together. This reduces the problems of flash defects and inconsistent product heights in the iron core during the injection molding process.

[0017] The design of the first push rod, the second push rod, the first guide slope, and the second guide slope improves the ease of adjusting the height of the iron chip.

[0018] By mounting the first and second push rods on the fixed base, and by setting the hydraulic cylinder with a connecting rod and a locking block, the adaptability of the height adjustment of the first and second push rods is improved. Attached Figure Description

The push rod assembly 2 is installed on the fixed base 1, and the adjustment assembly 3 is installed on one side of the fixed base 1. In use, the adjustment assembly 3 adjusts the height of the stacked iron cores through the push rod assembly 2 to reduce the flash caused by the height difference of individual iron cores after stacking.

[0027] Reference Figs. 2-3The push rod assembly 2 includes a first push rod 21 and a second push rod 22. The first push rod 21 is cylindrical in shape, and one end of the first push rod 21 passes through the fixed base 1. Several second push rods 22 are evenly spaced around the axis of the first push rod 21, and one end of each of the second push rods 22 protrudes from the fixed base 1. To improve the stability of the first push rod 21 and the second push rod 22 on the fixed base 1, a positioning block 23 is provided at one end of each of the first push rod 21 and the second push rod 22. The positioning block 23 is integrally formed with the first push rod 21 and the second push rod 22. A fixing groove is provided on the fixed base 1, and the positioning block 23 on the first push rod 21 and the second push rod 22 engages with the fixing groove on the fixed base 1.

[0028] Reference Fig. 2 The adjusting assembly 3 includes an adjusting block 31, which is located on one side of the fixed base 1 and is locked to the fixed base 1 by bolts. In use, the adjusting block 31 locks the first ejector rod 21 and the second ejector rod 22 onto the adjusting block 31. Furthermore, one end of the first ejector rod 21 and the second ejector rod 22 forms a support surface 24. In use, the iron chip inside the injection mold rests on the support surface 24 of the first ejector rod 21 and the second ejector rod 22.

[0029] Reference Fig. 3 In use, the first push rod 21 passes through the middle of the iron core, and the second push rod lifts the outer side of the iron core, thereby improving the stability of the iron core height adjustment. Furthermore, the end face of the second push rod 22 forms a limiting groove 221, and the stacked iron core chips are engaged in the limiting groove 221 of the second push rod 22, thereby improving the stability of the iron core height during adjustment.

[0030] The fixed base 1 has a fixing hole 11. The first push rod 21 and the second push rod 22 pass through the fixing hole 11 on the fixed base 1. In use, the operator can select different first push rods 21 and second push rods 22 according to different iron cores and pass different first push rods 21 and second push rods 22 through the fixing hole 11 of the fixed base 1, so as to improve the adaptability of the fixed base 1 and at the same time improve the stability of the first push rods 21 and second push rods 22 on the fixed base 1, and prevent the first push rods 21 and second push rods 22 from shifting during use.

In use, the first guide slope 311 and the second guide slope 331 are arranged parallel and spaced apart. When the adjustment rod 33 moves towards the side closest to the adjustment block 31, the adjustment block 31 drives the fixed base 1 to lift the first push rod 21 and the second push rod 22. When the adjustment rod 33 moves away from the adjustment block 31, the adjustment block 31 drives the fixed base 1 to lower the first push rod 21 and the second push rod 22.

[0032] Furthermore, the end of the adjusting rod 33 furthest from the adjusting block 31 has a slot 332. The slot 332 has a T-shaped cross-section and is open towards the side closest to the hydraulic cylinder 32. A connecting rod 34 is provided on the hydraulic cylinder 32.
