Abstract
Description
Technical Field
[0001] The invention relates to the technical field of plastic shell shaping, in particular to a plastic shell shaping device and method. Background Art
[0002] The structure of a plastic shell is as follows Figure 1~Figure 2 As shown, the top of the plastic shell is closed and its overall shape is rectangular. This plastic shell is formed by injection molding of an injection mold. When used, electronic products can be installed therein to protect the electronic products.
[0003] When the plastic shell is taken out of the injection mold, the left side plate 1, right side plate 2, front plate 3 and rear plate 4 of the plastic shell are not in a vertical state, but are bent inwards, while the four plates of the plastic shell required by the customer are all in a vertical state. Therefore, the worker needs to reshape the plastic shell just taken out of the injection mold so that the left side plate 1, right side plate 2, front plate 3 and rear plate 4 of the plastic shell are all in a vertical state, thereby meeting the customer's needs.
[0004] The method for workers in the workshop to reshape the plastic shell just taken out of the injection mold is: the worker wears heat-insulating gloves and presses the deformed part on the inner side of the front plate 3 with his hand until the front plate 3 of the plastic shell changes from a bent state to a vertical state; then the worker presses the deformed part on the inner side of the right plate 2 with his hand, directly changing the right plate 2 of the plastic shell from a bent state to a vertical state, thereby finally realizing the shaping of the plastic shell just taken out of the injection mold.
[0005] However, although this method can reshape the plastic shell, it still has the following technical defects: Workers need to press the deformed parts of the front plate 3 and the inner side of the right side plate 2 of the plastic shell in two steps in turn. There are many shaping steps, which results in a long time to complete the shaping of a plastic shell, thereby reducing the shaping efficiency of the plastic shell. In addition, the entire shaping process is completed manually, which not only increases the work intensity of the workers, but also results in a long time to complete the shaping of a plastic shell, further reducing the shaping efficiency of the plastic shell.
[0006] Therefore, there is an urgent need for a shaping device and method that can greatly reduce the work intensity of workers and greatly improve the shaping efficiency of plastic shells. Summary of the invention

[0017] The top seat 6 is provided with two pushing components 11 for applying pressure to the front plate 3 and the right side plate 2 of the plastic shell. The structure of the pushing component 11 on the front side is the same as that of the pushing component 11 on the right side. The two pushing components 11 are respectively opposite to the two wedge-shaped surfaces 10 on the movable block 9. The pushing component 11 located on the front side includes a strip guide groove 12 opened on the top surface of the top seat 6 and connected to the through groove 7, and a sliding plate 13 slidably installed in the strip guide groove 12. A limit plate 14 fixedly arranged on the top surface of the top seat 6 is arranged directly above the sliding plate 13. The limit plate 14 limits the vertical freedom of the sliding plate 13. A support platform 15 is fixedly arranged on the top surface of the sliding plate 13. A push plate 16 is fixedly arranged on the top surface of the support platform 15. The front end surface of the push plate 16 is a vertical surface 17, and the rear end surface of the push plate 16 is an inclined surface 18, and the inclined surface 18 of the push plate 16 matches the front wedge surface 10 of the movable block 9.
[0018] The shaping device also includes a controller, which is electrically connected to the solenoid valve of the shaping cylinder 8 via a signal line. Workers can control the lifting and lowering of the piston rod of the shaping cylinder 8 through the controller, thereby driving the lifting and lowering of the movable block 9.
[0019] A shaping method for a plastic shell comprises the following steps: S1. Workers will Figure 1~Figure 2 The inner cavity of the plastic shell shown is sleeved on the outside of the movable block 9 from top to bottom, as shown in FIG. Fig.10 As shown, the front plate 3 of the plastic shell is supported on the top surface of the support platform 15 of the front side pushing component 11, and the deformed portion on the inner side of the front plate 3 is opposite to the vertical surface 17 of the front side pushing component 11. At the same time, the right side plate 2 of the plastic shell is supported on the top surface of the support platform 15 of the right side pushing component 11, and the deformed portion on the inner side of the right side plate 2 is opposite to the vertical surface of the right side pushing component 11; S2, the piston rod of the shaping cylinder 8 is controlled to retract downward, the piston rod drives the movable block 9 to move downward, the movable block 9 drives the wedge-shaped surface 10 located on the front side and right side thereof to move downward synchronously, the wedge-shaped surface 10 located on the front side of the movable block 9 presses downward the inclined surface 18 of the push plate 16 of the front side pushing assembly 11, the push plate 16 drives the sliding plate 13 and the support platform 15 to move forward synchronously, and the vertical surface 17 of the push plate 16 applies pressure to the deformed portion on the inner side of the front plate 3; At the same time, the wedge-shaped surface 10 on the right side of the movable block 9 presses down the inclined surface 18 of the push plate 16 of the right push assembly 11, and the push plate 16 drives the sliding plate 13 and the support platform 15 to move rightward synchronously, and the vertical surface 17 of the push plate 16 presses the deformed portion on the inner side of the right side plate 2; When the piston rod of the shaping cylinder 8 is retracted downward to the set stroke, the front plate 3 and the right plate 2 of the plastic shell can be shaped from the bent state to the vertical state, and then the rear plate 4 and the left plate 1 of the plastic shell can be shaped from the bent state to the vertical state, thereby finally realizing the shaping of the plastic shell just taken out of the injection mold; S3. After the plastic shell is shaped, the worker controls the piston rod of the shaping cylinder 8 to extend upward, and the piston rod drives the movable block 9 to move upward, and the movable block 9 drives the two wedge-shaped surfaces 10 thereon to move upward synchronously, and the wedge-shaped surface 10 of the movable block 9 is separated from the inclined surface 18 of the push plate 16, and then the worker takes away the shaped plastic shell; S4: The worker repeats the operations of steps S1 to S3 for multiple times, and can continuously shape multiple plastic shells.
[0020] Among them, it can be seen from steps S1 to S3 that the worker only needs to put the plastic shell on the outside of the movable block 9 first, and then control the downward retraction of the piston rod of the shaping cylinder 8, so that the two wedge-shaped surfaces 10 of the movable block 9 can press down the inclined surfaces 18 of the two pushing components 11 respectively, thereby respectively pressing the front plate 3 and the right side plate 2 through the vertical surfaces 17 of the push plates 16 of the two pushing components 11, thereby finally realizing the rapid shaping of the plastic shell.
[0021] It can be seen that compared with the manual shaping method in the workshop, the shaping device does not require workers to shape the front plate 3 and the right side plate 2 of the plastic shell in two steps, but can shape the front plate 3 and the right side plate 2 of the plastic shell in one go and automatically, thereby completing the shaping of a single plastic shell in a short time, thereby greatly improving the shaping efficiency of the plastic shell. In addition, there is no need for workers to wear heat-insulating gloves for shaping, but automatic shaping is achieved, thereby greatly reducing the work intensity of workers.
