Description

Technical Field

[0001] This utility model belongs to the field of flat panel component manufacturing technology, and specifically relates to a shaping fixture. Background Technology

[0002] For some flat metal components, high pressure can be applied using equipment such as stamping presses to perform one or multiple stampings to achieve the desired shape. For example, minor deformation of some back shell components can be restored to their original shape through stamping.

[0003] Existing shaping fixtures cause the workpiece to adhere too tightly to the mold surface after shaping, increasing the demolding force required when opening the mold. When the demolding force is insufficient to overcome the adhesion between the workpiece and the upper mold, the workpiece will come out with the upper mold and become difficult to remove.

[0004] In view of this, the present invention provides a shaping fixture to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a shaping fixture, comprising a lower mold base and an upper mold base, wherein a shaping module for acting on a workpiece is further provided between the lower mold base and the upper mold base, the shaping module comprising a lower mold disposed on the top of the lower mold base, the lower mold having a positioning boss for positioning the workpiece, and a through groove that is relatively deepened on the top surface of the positioning boss;

[0006] The lower mold base is also provided with a positioning component. The positioning component has a limiting block that moves in the horizontal direction and extends into the through groove at one end. When the workpiece is placed on the lower mold, the movement of the limiting block forms a clamping force on the inside of the workpiece to position the workpiece.

[0007] As a preferred embodiment of the shaping fixture of this utility model, the shaping module further includes an upper mold disposed at the bottom of the upper mold base, the upper mold being able to close with the lower mold to extrude and shape the workpiece.

[0008] As a preferred embodiment of the shaping fixture of this utility model, the positioning component further includes a positioning frame, a linear drive is horizontally arranged on one side of the positioning frame, the movable end of the linear drive is connected to a movable frame, and the limiting block is installed on the top of the movable frame.

[0009] As a preferred embodiment of the shaping fixture of this utility model, a slide rail is further provided between the movable frame and the lower mold base to enable the movable frame to slide stably.

[0010] As a preferred embodiment of the shaping fixture of this utility model, the slide rail includes a guide rail mounted on the lower mold base and a slider mounted on the bottom of the movable frame and slidably connected to the guide rail.

[0011] As a preferred embodiment of the shaping fixture of this utility model, the lower mold base includes a base and support blocks disposed opposite to each other on the base, and the lower mold frame is mounted on the top of the two sets of support blocks.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model uses a positioning component that allows the linear drive component in the positioning component to drive the movable frame to move when the workpiece is placed on the lower mold. This, in turn, causes the limiting block to move in the opposite direction, thereby clamping and fixing the workpiece inside the mold. As a result, the workpiece will not be embedded in the upper mold during shaping and demolding, making it easier to remove the workpiece. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] This utility model relates to a shaping jig, such as Figures 1-2 As shown, the assembly includes a lower mold base 1 and an upper mold base 2, and a positioning component 4 for restricting workpiece movement, which is disposed opposite to each other on the lower mold base 1. A shaping module 3 for acting on the workpiece is also disposed between the lower mold base 1 and the upper mold base 2. The shaping module 3 includes a lower mold 302 disposed on the top of the lower mold base 1 and an upper mold 301 disposed on the bottom of the upper mold base 2. The upper mold 301 can close with the lower mold 302 to extrude and shape the workpiece. The lower mold base 1 includes a base 101 and support blocks 102 disposed opposite to each other on the base 101. The lower mold 302 is mounted on the top of the two sets of support blocks 102.

[0024] Specifically, such as Figures 4-6 As shown, the bottom of the upper mold 301 is provided with a shaping cavity (not marked in the figure), and the lower mold 302 has a positioning boss 3021 for preliminary positioning of the workpiece, and a through groove 3022 that is relatively deepened on the top surface of the positioning boss 3021. The positioning boss 3021 is adapted to the shaping cavity, and when the upper mold 301 and the lower mold 302 are closed, the positioning boss 3021 can extend into the shaping cavity. After extending in, there is a gap between the outer contour of the positioning boss 3021 and the inner wall of the shaping cavity. The space enclosed by this gap is the shape required for shaping.

[0025] Figure 3 This invention illustrates a specific embodiment of the positioning component 4, which has a positioning frame 401 mounted on the lower mold base 1. A linear drive 402 is horizontally arranged on one side of the positioning frame 401. The movable end of the linear drive 402 is connected to a movable frame 403. A limit block 404 is installed on the top of the movable frame 403.

[0026] In this embodiment, the linear drive 402 is preferably a cylinder, but it can also be an electric push rod, hydraulic rod, etc., and this application is not limited thereto. The limiting block 404 is L-shaped, with its top end extending into the through groove 3022 and lower than the top of the through groove 3022. The limiting block 404 is movable in the through groove 3022. In use, after the workpiece is placed on the positioning boss 3021 for initial positioning, the operation of the linear drive 402 drives the movable frame 403 to move, thereby allowing the limiting block 404 to move in the through groove 3022 and abut against the inner sidewall of the workpiece, forming a clamping and fixing of the workpiece.

[0027] Taking the flat plate back shell as an example: During use, the deformed flat plate back shell is placed on the positioning boss 3021 of the lower mold 302 for initial positioning. Then, through the operation of the positioning component 4, the limiting block 404 clamps and fixes the flat plate back shell inside. Through the operation of the stamping equipment, the upper mold base 2 gradually approaches the lower mold base 1, so that the upper mold 301 and the lower mold 302 close together. Figure 6 As shown, the shaping process of the flat plate back shell is achieved through the cooperation between the positioning boss 3021 and the shaping cavity.

[0028] Furthermore, in order to improve the mold closing accuracy of the upper mold 301 and the lower mold 302, a guide component is provided between the upper mold base 2 and the lower mold 302. The guide component includes a guide post 201 vertically disposed on the bottom surface of the upper mold base 2 and a guide groove 3023 formed on the top surface of the lower mold 302 that is adapted to the guide post 201. The adaptation includes positional and dimensional adaptation. When the upper mold 301 and the lower mold 302 are closed, and before the mold is fully closed, the guide post 201 can be preferentially inserted into the guide groove 3023 for adaptation, so as to improve the mold closing accuracy.

[0029] Furthermore, to improve the stability of the movable frame 403, a slide rail 5 is provided between the movable frame 403 and the base 101. The slide rail 5 includes a guide rail 501 mounted on the lower mold base 1 and a slider 502 mounted on the bottom of the movable frame 403 and slidably connected to the guide rail 501. The extension direction of the guide rail 501 is consistent with the movement direction of the movable end of the linear drive member 402. When the movable end of the linear drive member 402 extends or retracts, the movable frame 403 can move stably and with high precision with the cooperation of the guide rail 501 and the slider 502.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
