Description

Technical Field

[0001] This utility model relates to the field of iron core technology, and in particular to a clamping fixture for a die-casting mold for an aluminum rotor. Background Technology

[0002] A cast aluminum rotor consists of a rotor core and an aluminum cage, with the aluminum cage serving as a fastening element between the rotor guide rod and the core. During the manufacturing process, the rotor core is placed into a mold, molten aluminum is poured into the mold, and die-casting is performed. The molten aluminum encapsulates the rotor core and cools to form the aluminum cage. The cast aluminum rotor is then removed from the mold to obtain the finished motor cast aluminum rotor.

[0003] During the demolding process of cast aluminum rotors, the aluminum liquid will remain at a high temperature after solidification, which is difficult for workers to discern from the outside, thus posing a safety hazard. Utility Model Content

The drive unit is fixedly connected to the housing. The clamping unit includes a first clamping body and a second clamping body. The first clamping body is installed on the housing, and the second clamping body abuts against the output end of the drive unit. A clamping space is formed between the first clamping body and the second clamping body. The number of clamping units is multiple.

[0005] Furthermore, the clamping part includes a transmission gear, which is rotatably mounted on the housing. The first clamping body has a first rack in the middle, and the second clamping body has a second rack in the middle. The first rack meshes with the transmission gear, and the second rack meshes with the transmission gear.

[0017] 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.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / as well" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] The following describes the embodiments in conjunction with the appendix. Figure 1-3 This utility model will be described in further detail.

[0020] A clamping fixture for a die-casting mold for an aluminum rotor includes a housing 1, a drive unit 2, and a clamping unit 3.

[0021] The drive unit 2 includes a cylinder 21, a drive shaft 22, and a connecting plate 23. The cylinder 21 is connected to the connecting plate 23 via the drive shaft 22.

[0022] The clamping part 3 includes a first clamping body 31, a second clamping body 32, a transmission gear 33, an abutment component 34, and a positioning rod 35. The first clamping body 31 has a first rack 311 in the middle and a first gripper 312 at the end. The first clamping body 31 also has a positioning hole 313 located on one side of the first gripper 312. The bottom of the first gripper 312 has a first blocking plate 3121 and the top of the first blocking plate 3121 has a first bending part 3122. The second clamping body 32 has a second rack 321 in the middle and a second gripper 322 at the end. The second gripper 322 has a second blocking plate 3221 at the bottom and a second bend 3222 above the second blocking plate 3221. The first blocking plate 3121 and the second blocking plate 3221 extend in opposite directions. A clamping space for clamping the mold is formed between the first gripper 312 and the second gripper 322. The first bend 3122 and the second bend 3222 are used to increase the friction of the gripper on the mold. Specifically, in this embodiment, there are multiple clamping parts 3. The abutting component 34 includes an elastic element 341 and a guide shaft 342. The guide shaft 342 is installed inside the housing 1, and both ends of the guide shaft 342 extend into the first clamping body 31 and the housing 1. The elastic element 341 is installed on the guide shaft 342, and both ends of the elastic element 341 abut against the first clamping body 31 and the housing 1.

[0023] Connection relationship of clamping fixture for a die-casting mold for an aluminum rotor: The cylinder 21 of the drive unit 2 is fixedly connected to the housing 1. The first clamping body 31 and the second clamping body 32 are installed on the housing 1. The first clamping body 31 and the second clamping body 32 extend out of the housing 1 to form the first gripper 312 and the second gripper 322. The transmission gear 33 is installed inside the housing 1. The first rack 311 and the second rack 321 are connected by transmission gear 33. Specifically, the first rack 311 and the second rack 321 are arranged in parallel. The connecting plate 23 of the drive unit 2 abuts against the second clamping body 32. The positioning rod 35 is engaged with the positioning hole 313. Multiple clamping parts 3 are installed on the housing 1 as described above.

[0024] The working principle of a clamping fixture for a die-casting mold of an aluminum rotor: The cylinder 21 of the drive unit 2 drives the connecting plate 23 to abut against the second clamping body 32. The second clamping body 32 moves outward, and through the transmission gear 33, the first clamping body 31 moves in the opposite direction, thereby expanding the clamping space. The elastic element 341 of the contact assembly 34 is compressed. When the mold enters the clamping space, the cylinder 21 contracts, and the elastic element 341 abuts against the first clamping body 31, causing the first clamping body 31 to move outward. The second clamping body 32 moves in the opposite direction, thereby reducing the clamping space and completing the clamping of the mold. When it is necessary to disassemble the mold step by step, the positioning bar 35 is pulled to make the second clamping body 32 move outward and expand the clamping space. When the end of the first clamping body 31 passes the positioning hole 313, the positioning bar 35 is pressed down to prevent the first clamping body 31 from rebounding, thereby keeping part of the clamping space expanded, which facilitates the step-by-step disassembly of the mold.

[0025] The advantages of this utility model are: the mold is clamped by multiple clamping parts 3 and their clamping spaces, avoiding direct contact between the staff and the mold during the mold transfer and disassembly process; by manipulating some of the clamping parts 3, some of the clamping spaces are kept open, and the mold parts are disassembled in sequence, reducing safety hazards.

[0026] The above embodiments only illustrate one implementation of the present utility model, and should not be construed as limiting the scope of the utility model patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of the present utility model, and all of these fall within the protection scope of the present utility model.
