[0065] See also Figure 5 The method for pre-adjusting the size of the lower cover forming mold is as follows:

[0066] S1: Positioning the inner box standard mold on the stamping side of the template;

[0067] S2: moving the first fixing member and the second fixing member along the first direction until the first fixing member and the second fixing member respectively abut against the two side walls of the inner box standard mold in the first direction, and moving the third fixing member and the fourth fixing member along the second direction until the third fixing member and the fourth fixing member respectively abut against the two side walls of the inner box standard mold in the second direction;

[0068] In this step, the inner box standard molds of different models and specifications can be positioned by adjusting the positions of the first fixing member, the second fixing member, the third fixing member and the fourth fixing member, and because the first positioning column and the second positioning column are arranged on the third fixing member, the third fixing member can drive the first positioning column and the second positioning column to move along the second direction when moving, that is, the positions of the first positioning column and the second positioning column in the second direction are determined while adjusting and determining the position of the third fixing member, and the third positioning column and the fourth positioning column are arranged on the fourth fixing member, so that the fourth fixing member can drive the third positioning column and the fourth positioning column to move along the first direction when moving, that is, the positions of the third positioning column and the fourth positioning column in the second direction are determined while adjusting and determining the position of the fourth fixing member, so that in the subsequent adjustment steps, there is no need to adjust and determine the positions of the first positioning column, the second positioning column, the third positioning column and the fourth positioning column in the second direction, and only the positions in the first direction need to be determined, thereby reducing the adjustment steps, achieving rapid adjustment, and greatly improving work efficiency.

[0069] It should be noted that the movement and positioning order of the first fixing member, the second fixing member, the third fixing member and the fourth fixing member is not fixed, as long as the first fixing member, the second fixing member, the third fixing member and the fourth fixing member are respectively abutted against the corresponding side walls of the inner box standard mold.

[0070] S3: fixing and positioning the lower cover standard mold on the inner box standard mold;

[0071] It should be noted that the order of this step and step S2 is not restricted, and this step can be performed before step S2, that is, the lower cover standard mold is first fixedly installed on the inner box standard mold, and then the positions of the first fixing member, the second fixing member, the third fixing member and the fourth fixing member are adjusted.

[0072] S4: moving the first positioning post and the second positioning post along the first direction until the first positioning post and the second positioning post respectively abut against two of the four recesses of the lower cover standard mold, and moving the third positioning post and the fourth positioning post along the first direction until the third positioning post and the fourth positioning post respectively abut against the other two recesses of the lower cover standard mold;

[0073] It should be noted that the movement and positioning order of the first positioning column, the second positioning column, the third positioning column and the fourth positioning column is not fixed, as long as the first positioning column, the second positioning column, the third positioning column and the fourth positioning column are respectively in contact with the corresponding recesses.

[0074] In this step, the positions of the first positioning column, the second positioning column, the third positioning column and the fourth positioning column in the first direction are adjusted and determined, that is, the first positioning column, the second positioning column, the third positioning column, the fourth positioning column, the first fixing member, the second fixing member, the third fixing member and the fourth fixing member are combined according to the size of the inner mold-surrounding strip combination and the lower cover to be formed to form the corresponding pre-forming cavity, and the pre-forming cavity can ensure the fitting effect of the lower cover to be formed with the inner mold-surrounding strip combination after forming.

[0075] S5: Remove the lower cover standard mold and the inner box standard mold.

[0076] In this step, after the size pre-adjustment of the lower cover molding mold is completed, the lower cover standard mold and the inner box standard mold are removed, and the lower cover molding mold can be put into use in the lower cover molding production process.

[0077] In the technical solution of the size pre-adjustment method of the lower cover forming mold provided by the present invention, the positions of the first fixing member, the second fixing member, the third fixing member and the fourth fixing member are moved and adjusted to adapt to the inner box standard molds of different specifications and sizes, and the positions of the first positioning column, the second positioning column, the third positioning column and the fourth positioning column are moved and adjusted to adapt to the lower cover standard molds of different specifications and sizes. In this way, the first positioning column, the second positioning column, the third positioning column, the fourth positioning column, the first fixing member, the second fixing member, the third fixing member and the fourth fixing member can enclose different pre-forming cavities to be suitable for the lower covers to be formed of various specifications to be folded along the folding line to form flanging for forming processing, that is, there is no need to replace different lower cover forming molds in the lower cover forming device to complete the forming of the lower covers to be formed of different specifications and sizes. At the same time, since the position adjustment of the first positioning column, the second positioning column, the third positioning column and the fourth positioning column in the second direction is completed at the same time as the position adjustment of the third fixing member and the fourth fixing member, the adjustment steps are reduced, rapid adjustment is achieved, and the adjustment efficiency is greatly improved, thereby improving the order change processing efficiency.
