Description

Technical Field

[0001] This application relates to the field of mold technology, specifically to a casting mold for an aluminum alloy bearing lower support. Background Technology

[0002] Aluminum alloy bearing lower support casting mold is a casting tool specifically used for producing aluminum alloy bearing lower supports.

[0003] This mold uses a series of precisely designed components working together to stamp and eject aluminum alloy materials, thereby producing a bearing lower support that meets the requirements.

[0004] For example, the patent with publication number CN214108750U discloses a casting mold that facilitates material discharge. By setting a demolding mechanism, the molded product does not need to be manually removed from the cavity during material discharge. The casting parts can be ejected by pressing the demolding mechanism, which helps to improve material discharge efficiency and reduce labor intensity.

[0005] In actual use, the contact area between the aluminum alloy bearing lower support and the mold is large after molding. If direct vertical ejection is adopted, the contact area is not effectively reduced and the frictional resistance increases significantly. This ejection method not only increases the difficulty of demolding, but may also cause scratches, wear or cracks on the surface of the workpiece due to friction. Such damage affects the appearance, weakens the structural strength, and reduces the assembly accuracy and service life.

[0006] Therefore, it is necessary to provide a casting mold for the lower support of an aluminum alloy bearing to solve the above problems.

[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

Detailed Implementation

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0035] like Figures 1-2 As shown, this application provides a casting mold for an aluminum alloy bearing lower support. The casting mold for an aluminum alloy bearing lower support is mainly installed inside the factory and is mainly used to manufacture bearing lower supports. Specifically, the casting mold for an aluminum alloy bearing lower support includes a die casting machine 1 installed inside the factory to facilitate subsequent molding operations.

[0036] Furthermore, the die-casting machine 1 includes a pressure plate 10, which is adapted to move vertically under the action of an external force. In this application, the external force can be a cylinder or a hydraulic cylinder. At the same time, a mold 2 is provided at the lower end of the pressure plate 10. The mold 2 is used to make the lower support of the bearing. The mold 2 includes an upper mold 20 fixedly provided at the lower end of the pressure plate 10, and a lower mold 21 is provided on the die-casting machine 1 at a position directly below the upper mold 20. The lower mold 21 cooperates with the upper mold 20 to facilitate the molding operation.

[0037] Meanwhile, a mold cavity 22 is provided between the lower mold 21 and the upper mold 20. The mold cavity 22 is used to accommodate the formed bearing lower support. A mold base 23 is fixedly provided at the lower end of the lower mold 21. The mold base 23 is used to support the various parts of the mold 2 so that the mold 2 can work stably.

[0038] Before pressing and molding, the die-casting machine 1 is started first. The upper mold 20 is driven to move closer to the lower mold 21 through the pressure plate 10 until the upper mold 20 is completely attached to the lower mold 21 and reaches a closed state, thereby forming a complete mold cavity 22. Then, aluminum alloy material is injected into the mold cavity 22, so that the aluminum alloy material fills every corner of the mold cavity 22 and forms the shape of the lower support of the aluminum alloy bearing. After the aluminum alloy material is completely solidified, the die-casting machine 1 separates the upper mold 20 and the lower mold 21 through the pressure plate 10, exposing the formed lower support of the aluminum alloy bearing.

[0039] In order to facilitate material removal after molding, an ejection mechanism 3 is provided at the lower end of the mold base 23. The ejection mechanism 3 ejects the molded aluminum alloy bearing lower support, thereby facilitating material removal.

[0040] The ejection mechanism 3 includes a fixed frame 31 fixedly mounted at the lower end of the mold base 23. A cylinder 32 is mounted on the fixed frame 31. To prevent surface scratches caused by forcibly ejecting the molded lower bearing support, a pre-loosening component 33 is provided at the output end of the cylinder 32. Figures 2-3 As shown, the pre-loosening assembly 33 is used to loosen the lower support of the aluminum alloy bearing before ejection, thereby reducing ejection resistance;

[0041] The pre-loosening assembly 33 includes a fixed seat 330 fixedly installed at the output end of the cylinder 32, and a vertical plate 334 fixedly installed on one side of the fixed seat 330. Multiple sets of guide plates 335 are installed on the vertical plate 334, and a main shaft 333 is slidably installed on the upper end of the guide plate 335, so that the main shaft 333 can slide vertically up and down along the guide plate 335.

[0042] A motor 331 is fixedly installed on one side of the vertical plate 334. The output end of the motor 331 passes through the vertical plate 334 and is fixedly connected to an eccentric shaft 332. The other end of the eccentric shaft 332 is rotatably connected to one end of the main shaft 333. Thus, when the motor 331 is started, it can drive the main shaft 333 to slide vertically up and down along the guide plate 335 through the eccentric shaft 332.

[0043] Meanwhile, a top plate 336 is fixedly installed at the other end of the main shaft 333, and a through hole 337 is provided on the mold base 23. The through hole 337 is used to allow the main shaft 333 and the upper top plate 336 to pass through. A hole 338 is provided at the lower end of the lower mold 21. The size of the hole 338 matches the size of the top plate 336 so that the top plate 336 can smoothly pass through the hole 338 to contact the formed lower bearing support, thereby facilitating subsequent loosening and ejection operations.

[0044] It should be noted that, in the initial state, the top plate 336 is located inside the hole 338, so as to facilitate the sealing operation of the hole 338, thereby allowing the molding operation to proceed smoothly;

[0045] When the molding is complete and the material needs to be removed, the motor 331 can be started first to drive the main shaft 333 to slide vertically up and down along the guide plate 335 through the eccentric shaft 332. At this time, the top plate 336 is also driven by the main shaft 333 to continuously lift the lower support of the bearing over a short distance until the lower support of the bearing is loosened. Then the cylinder 32 can be started to push the top plate 336 to push it out, thereby avoiding the violent friction that may occur if it is pushed out directly.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
