As can be seen in the example of FIG. 7, for example, in this step, the front and back of the case 10 are attached to the seating portion 510 so that the case 10 is accurately inserted and seated in the seating portion 510. It is advisable to seat it properly.

For example, step (S2-4) may be performed before step (S2-2) or step (S2-3).

Step (S2-5) is an operation start step in which the operation of the injection case deformed part correction device 900 is started by pressing the start button 110 described above after performing steps (S2-1) to (S2-4). all.

Step (S2-6) is a heating step in which the deformed case 10 is pressed and heated using the heating cylinder unit 300 to restore the deformed portion of the case 10 to its original state. As can be seen in the example of FIG. 8, for example, the heating cylinder unit 310 and the heating unit 320 descend to pressurize and heat the deformed case 10, and after a predetermined time (about 6 seconds) has elapsed It can rise back to its original position.

As can be seen in the example of FIG. 9, in step (S2-7), the heating cylinder unit 300 is raised back to its original position in step (S2-6) and then the moving part 520 of the seating unit 500 is operated. This is a moving step in which the seating portion 510 is moved below the cooling cylinder unit 400 located next to the heating cylinder unit 300.

In step (S2-8), the case 10 heated under the heating cylinder unit 300 moves below the cooling cylinder unit 400 and then connects the cooling cylinder unit 410 and the cooling unit ( This is a cooling step in which 420) descends to pressurize and cool the heated case 10.

As can be seen in the example of FIG. 10, for example, the cooling cylinder unit 410 and the cooling unit 420 descend to pressurize and cool the heated case 10, and after a predetermined time (about 6 seconds) has elapsed, It can rise back to its original position. For example, after the cooling cylinder unit 400 is raised to its original position, the seating portion 510 may be moved back to a position below the heating cylinder unit 300 by the moving portion 520.

Step (S2-9) is a stop step in which the operation of the injection case deformed part correction device 900 is stopped by pressing the stop button 120 described above. For example, if a problem occurs in the above-described steps (S2-1) to (S2-8) or in an emergency, the stop button 120 can be pressed to stop the operation or be reset.

As can be seen in the example of FIG. 11, the case 10 deformed by the correction method using the injection case deformed part correction device 900 is quickly, accurately and conveniently restored to its original state, improving the durability of the product and eliminating expensive costs. There is no need to replace it with a new product, so it is highly economical.

Step (S3) is a shipping step in which the injection molded product corrected after step (S2) is packaged and shipped, or if the injection molded product is determined to be good and not deformed in the deformation determination step, the product is packaged and shipped.
