Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to an ejection structure that improves the ejection efficiency and accuracy of iron-silicon-aluminum soft magnetic molds. Background Technology

[0002] In the mold industry, molds are various molds and tools used in injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, and other methods to obtain the desired products. In short, a mold is a tool used to create shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the shaping of the object by changing the physical state of the material being molded. Iron-silicon-aluminum soft magnetic cores are mostly ring-shaped structures and also require mold processing during production. After being shaped by the mold, the iron-silicon-aluminum soft magnetic cores need to be demolded.

[0003] However, existing methods for demolding and ejecting iron-silicon-aluminum soft magnetic cores have the following problems: Current demolding methods primarily employ an ejection mechanism to eject the cores one by one. When multiple cores need to be demolded, the demolding efficiency is low, and there is a lack of means for rapid demolding of iron-silicon-aluminum soft magnetic cores. Therefore, it is necessary to design corresponding technical solutions to address these problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution: an ejection structure for improving the ejection efficiency and accuracy of iron-silicon-aluminum soft magnetic molds, comprising a mounting frame 2 with a mounting port 1 in the middle and a mold body 3 embedded in the mounting port 1. The surface of the mold body 3 is evenly provided with several sets of mold forming ports 4. A floating ejection mechanism is provided below the mounting frame 2. The floating ejection mechanism includes a column 5, a base 6, a floating plate 7, a rotating roller 8, a gear 9, a rack 10, a guide plate 11, and a locking device 12. The column 5 is provided with several sets corresponding to several sets of mold forming ports 4. The base plate 6 is fixed to the column 5 and used in conjunction with the model forming opening. The floating plate 7 is fixed to the bottom of several sets of columns 5. The rotating roller 8 is divided into two sets and is rotatably installed below the floating plate 7. One end of the rotating roller 8 is connected to the gear 9. The rack 10 is located below the two sets of gears 9 and meshes with the two sets of gears 9. The guide plate 11 is located below the gears 9 and has a guide groove 13 on its top. The rack 10 is slidably set in the guide groove 13. The guide plate 11 has an adjustment groove 14 in the middle. The locking device 12 is set in the adjustment groove 14 and its inner end is connected to the rack 10.

[0020] Further improvements, such as Figure 1 As shown, the diameter of the base plate 6 is equal to the diameter of the mold forming opening 4. The base plate 6 is movably disposed inside the mold forming opening 4, and the mold forming opening 4 is sealed by the base plate 6.

[0021] Further improvements, such as Figure 2 As shown, the bottom of the floating plate 7 is symmetrically provided with two sets of arc-shaped grooves 15, and the rotating roller 8 is rotatably disposed in the arc-shaped grooves 15.

[0022] Further improvements, such as Figure 2 As shown, the rotating roller 8 includes a roller body 16 and an actuating protrusion 17 mounted on the roller body 16. The actuating protrusion 17 has a fan-shaped cross-section and one end is narrower than the other end. The actuating protrusion 17 contacts the arc-shaped groove 15. During the rotation of the roller body 16, the actuating protrusion 17 acts on the floating plate 7, causing the floating plate 7 to be adjusted up and down.

[0023] Further improvements, such as Figure 3 As shown, the locking device 12 includes a pull rod 18 and a connecting piece 19 fixed on the pull rod 18. The inner end of the pull rod 18 is connected to the rack 10. A positioning bolt 20 is inserted through the connecting piece 19. By pulling the pull rod 18, the rack 10 can be adjusted laterally, thereby driving the gear 9 to rotate. During the rotation of the gear 9, the rotating roller 8 is driven to rotate, which can realize the up and down adjustment of the floating plate 7.

[0024] Specifically, a row of positioning holes 21 is provided below the adjusting groove 14. The positioning holes 21 are used in conjunction with the positioning bolts 20 to position the rack 10.

[0025] In use: After the processing and molding within the mold forming opening 4 is completed, when it needs to be removed, the operator can pull the pull rod 18 to drive the rack 10 to make lateral adjustment, which in turn drives the gear 9 to rotate. During the rotation of the gear 9, the rotating roller 8 rotates. During the rotation of the roller 16, the roller body 16 acts on the floating plate 7 by moving the protrusion 17, causing the floating plate 7 to adjust upward. During the upward movement of the floating plate 7, the column 5, the base plate 6, and the iron-silicon-aluminum soft magnetic core formed on the base plate move upward synchronously and separate from the mold forming opening 4, completing the rapid demolding process of the iron-silicon-aluminum soft magnetic core. The operator can then directly remove the iron-silicon-aluminum soft magnetic core. The operation is simple and easy to use.
