Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example 1

[0023] This utility model provides a technical solution: such as Figure 1-3 As shown, a rapid prototyping device for tablet computer casing production includes a processing worktable 100. A base plate 101 is mounted on the upper end of the processing worktable 100. A mold table 103 is fixedly connected to the upper end of the base plate 101. Positioning components 200 are arranged on both sides of the mold table 103. The positioning components 200 include telescopic hydraulic cylinders 201. One end of the telescopic hydraulic cylinder 201 is fixedly connected to one end of a support plate 102. The lower end of the support plate 102 is located on the upper end of the processing worktable 100. One end of the telescopic hydraulic cylinder 201 is provided with a telescopic extension... The telescopic guide column 202 is driven by the telescopic hydraulic cylinder 201, which drives the telescopic guide column 202 to move. One end of the telescopic guide column 202 is rotatably connected to the mounting block 204. When the telescopic guide column 202 is pushed, the mounting block 204 rotates on the telescopic guide column 202. The mounting block 204 is fixedly installed on the upper end of the first positioning plate 205 and the second positioning plate 206. One end of the first positioning plate 205 and the second positioning plate 206 is provided with a rubber pad 208, which contacts both sides of the tablet computer shell material.

[0024] Furthermore, such as Figure 2-3 As shown, rotating rods 207 are provided on both sides of the first positioning plate 205 and the second positioning plate 206. The rotating rods 207 are rotatably connected to one end of the connecting rod 209. One end of the connecting rod 209 is rotatably connected to one end of the fixing block 210. The lower end of the fixing block 210 is located on the upper end of the base plate 101.

[0025] In this solution, the tablet computer shell workpiece to be processed is placed on the mold table 103, and the telescopic hydraulic cylinder 201 is activated. The telescopic hydraulic cylinder 201 pushes the telescopic guide column 202 to extend, and the retracted guide column pushes the mounting block 204, so that the first positioning plate 205 and the second positioning plate 206 rotate toward the mold. During the rotation, the rotating structure formed by the rotating rod 207 and the connecting rod 209 ensures that the positioning plate rotates smoothly. When the first positioning plate 205 and the second positioning plate 206 contact the two sides of the tablet computer shell workpiece, positioning is performed, which can position and clamp the tablet computer shell workpiece, avoiding the vibration generated during the stamping of the forming device and causing the tablet computer shell workpiece to shift on the mold table 103.

[0026] In this embodiment, through the first positioning plate 205 and the second positioning plate 206, the tablet computer shell workpiece is stably positioned and clamped during the stamping process of the forming device, which can effectively avoid the displacement caused by vibration, reduce dimensional deviation and scrap rate, and ensure that the tablet computer shell after forming has a flat and smooth appearance, and the shape of the edges and corners is more regular.

[0027] Example 2

[0028] like Figure 2-3 As shown, a connecting plate 203 is fixedly installed on the outer side of the telescopic guide post 202. L-shaped rods 211 are rotatably connected to both sides of the lower end of the connecting plate 203. One end of the L-shaped rods 211 is rotatably connected to both sides of the top plate 213.

[0029] like Figure 2-4 As shown, a top rod 212 is fixedly connected to the upper end of the top plate 213. The top rod 212 is connected through the inside of the mold table 103. A top hole 104 is opened inside the mold table 103. The top rod 212 is movably sleeved inside the top hole 104. The top plate 213 is set inside the bottom plate 101. A through opening 105 is opened inside the bottom plate 101.

[0030] In this scheme, when the first positioning plate 205 and the second positioning plate 206 finish positioning the tablet computer case workpiece, through the above operation in Embodiment 1, and the first positioning plate 205 and the second positioning plate 206 rotate, since the connecting plate 203 is fixedly installed on the outside of the telescopic guide post 202, when the telescopic guide post 202 extends, it drives the connecting plate 203 to move together. The forward movement of the connecting plate 203 will cause the L-shaped rod 211 to rotate around its connection point with the connecting plate 203. When the L-shaped rod 211 rotates, it pushes the top plate 213 to move upward, further driving the top rod 212 to move upward in the top hole 104 of the mold table 103. After the tablet computer case workpiece is formed, the tablet computer case workpiece is ejected from the mold table 103.

[0031] In this embodiment, the positioning of the tablet computer shell workpiece is completed by the first positioning plate 205 and the second positioning plate 206. The forward movement of the connecting plate 203 causes the L-shaped rod 211 to rotate around the connection point between it and the connecting plate 203. When the L-shaped rod 211 rotates, it pushes the top plate 213 to move upward, which in turn drives the ejector rod 212 to move upward in the top hole 104 of the mold table 103. The ejector rod 212 can quickly eject the formed tablet computer shell workpiece from the mold table 103, avoiding the slow and laborious problems that may occur with manual demolding.

[0032] This utility model provides a rapid prototyping device for tablet computer shell production. The specific working principle is as follows: The tablet computer shell workpiece to be processed is placed on the mold table 103. The telescopic hydraulic cylinder 201 is activated, pushing the telescopic guide column 202 to extend. The retracting guide column pushes the mounting block 204, causing the first positioning plate 205 and the second positioning plate 206 to rotate towards the mold. During rotation, the rotating structure formed by the rotating rod 207 and the connecting rod 209 ensures the stable rotation of the positioning plates. When the first positioning plate 205 and the second positioning plate 206 contact both sides of the tablet computer shell workpiece, positioning is achieved. This clamping and positioning of the tablet computer shell workpiece prevents vibration during stamping by the forming device from damaging the workpiece. When an offset occurs on the mold table 103, after the first positioning plate 205 and the second positioning plate 206 finish positioning the tablet computer case workpiece, through the above operation in Embodiment 1, and the first positioning plate 205 and the second positioning plate 206 rotate, since the telescopic guide post 202 is fixedly installed with the connecting plate 203 on the outside, when the telescopic guide post 202 extends, it drives the connecting plate 203 to move together. The forward movement of the connecting plate 203 will cause the L-shaped rod 211 to rotate around its connection point with the connecting plate 203. When the L-shaped rod 211 rotates, it pushes the top plate 213 to move upward, further driving the top rod 212 to move upward in the top hole 104 of the mold table 103. After the tablet computer case workpiece is formed, the tablet computer case workpiece is ejected from the mold table 103.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
