Description

Technical Field

[0001] This invention relates to the field of molds for side-flipping of automotive seat back panels. Background Technology

[0002] The structure of the backrest side panel of a car seat is usually irregular in shape, so during the processing and production of the backrest side panel, it is necessary to perform stamping processing on some parts of the backrest side panel. When using a side-flipping die to process one side of the backrest side panel, the stamping block of the existing side-flipping die is prone to displacement when stamping the side of the backrest, which can easily lead to stamping position misalignment. Therefore, the existing side-flipping die needs to be improved. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the prior art, the present invention provides a side-flipping mold for a car seat back panel, which ensures that the side-flipping position of the back panel after being pressed and stabilized is within the stamping zone, and then the side-flipping stamping block moves along the stamping zone to stamp the side-flipping position, thereby avoiding the situation where the stamping position is easily misaligned.

[0004] Technical solution: To achieve the above objectives, the technical solution of the present invention is as follows:

[0005] A side-flipping mold for a car seat back panel includes a lower side-flipping mold and an upper side-flipping mold. The lower side-flipping mold includes a limiting protrusion module, one side of which has a corresponding opening. One end of the limiting protrusion module gradually recesses to form a mating end. The upper side-flipping mold includes a relative template, on which a protruding block is arranged to mate with the mating end. One side of the protruding block has a single-sided opening that mates with the corresponding opening. The single-sided opening and the corresponding opening form a stamping area. A side-flipping stamping block on one side of the limiting protrusion module is arranged corresponding to the stamping area.

[0006] Furthermore, one end of the limiting protrusion module protrudes as a protruding end; the protruding end is set on the protruding block of the side-tilting lower template, and the protruding end is offset from the side-tilting stamping block.

[0007] Furthermore, one end face of the protruding block is a plane, and the plane is set corresponding to the protruding end; the plane is set away from the single-sided opening, and the single-sided opening is set corresponding to the mating end.

[0008] Furthermore, the single-sided opening forms a stepped shape with the surface of the protruding block; the top edge of the single-sided opening is adapted to the concave and convex surfaces of the protruding block, and the center of the top edge of the single-sided opening is recessed.

[0009] Furthermore, an installation notch is provided on one side of the convex module; the installation notch is positioned opposite to the corresponding opening; a stop block is fixedly provided inside the installation notch, and the stop block is positioned in cooperation with the side-flipping stamping block.

[0010] Furthermore, the side-tilting stamping block includes a connecting strip and a stamping block body; the driving device on the side-tilting lower template is driven to one side of the connecting strip; the other side of the connecting strip is fixed to the stamping block body by a number of clamping blocks; the end of the stamping block body away from the connecting strip is adapted to be set in the stamping zone.

[0011] A working method of a car seat back panel side-flipping mold: a relative template and a limiting convex template cooperate to press the back panel to be flipped. The position of the back panel to be flipped is in the stamping zone. The side-flipping stamping block moves and embeds into the stamping zone to stamp the position of the back panel to be flipped, causing the position of the back panel to be flipped to fold, thereby performing the side-flipping process.

[0012] Leave a stamping area at the position where the backrest side panel is to be flipped over, so as to avoid the backrest side panel from easily moving during the flipping process.

[0013] Beneficial effects: In this invention, the relative template and the limiting protruding template cooperate to press the backrest side panel to be flipped. The position of the backrest side panel to be flipped is in the stamping zone. The side-flipping stamping block moves and embeds itself in the stamping zone to stamp the position of the backrest side panel to be flipped, causing the position of the backrest side panel to be flipped to fold, thereby performing the side-flipping process. By leaving a stamping zone at the position of the backrest side panel to be flipped, the backrest side panel can be prevented from easily moving during the side-flipping process, and the stamping position is more accurate, avoiding stamping misalignment.

[0019] The invention will now be further described with reference to the accompanying drawings.

[0020] As attached Figure 1-5A side-flipping mold for a car seat back panel and its working method are disclosed, comprising a lower side-flipping mold 2 and an upper side-flipping mold 1. The lower side-flipping mold 2 includes a limiting protrusion module 21, one side of which has a corresponding opening 211. One end of the limiting protrusion module 21 gradually recesses to form a mating end 212. The upper side-flipping mold 1 includes a relative template 11, on which a protruding block 12 is disposed in relation to the mating end 212. One side of the protruding block 12 has a single-sided opening 121 that mates with the corresponding opening 211. The single-sided opening 121 and the corresponding opening 212 form a stamping section 3. A side-flipping stamping block 4 on one side of the limiting protrusion module 2 is disposed corresponding to the stamping section 3. The relative template and the limiting protruding template cooperate to press down on the backrest side panel to be flipped. The position of the backrest side panel to be flipped is in the stamping zone. The side-flipping stamping block moves and embeds itself in the stamping zone to stamp the position of the backrest side panel to be flipped, causing the backrest side panel to fold over, thereby performing the side-flipping process. By leaving a stamping zone at the position of the backrest side panel to be flipped, it is possible to prevent the backrest side panel from easily moving during the side-flipping process, and the stamping position is more accurate, avoiding stamping misalignment.

[0021] One end of the limiting protrusion module 21 protrudes as a protruding end 22; the protruding end 22 is set on the protruding block 51 of the side-flipping lower template 5, and the protruding end 22 is offset from the side-flipping stamping block 4; the non-stamped position is exposed, which can facilitate the installation and stabilization of the backrest side plate, and facilitate the installation onto the limiting protrusion module.

[0022] One end face of the protruding block 12 is a plane 122, which corresponds to the protruding end 22. The plane 122 is located away from the single-sided opening 121, which corresponds to the mating end 212. By using the plane to correspond to the mating end, it can be pressed against the backrest side plate for stable clamping, and it can avoid creating too many mating concave and convex structures, thus reducing the cost of the mold structure. The single-sided opening 121 and the surface of the protruding block 12 form a stepped shape. The top edge of the single-sided opening 121 is adapted to the concave and convex surfaces of the protruding block 12, and the middle of the top edge of the single-sided opening 121 is recessed. This facilitates the backrest side plate to be fitted and locked in the recessed position of the single-sided opening, preventing the backrest side plate from easily moving and preventing stamping misalignment.

[0023] The convex module 21 has an installation notch 24 on one side; the installation notch 24 is opposite to the corresponding opening 211; an abutment block 241 is fixedly installed in the installation notch 24, and the abutment block 241 is opposite to and cooperates with the side-flipping stamping block 4; the abutment block abuts against one side of the backrest side plate and can cooperate with the side-flipping stamping block, thereby stamping the backrest side plate.

[0024] The side-flipping stamping block 4 includes a connecting strip 41 and a stamping block 42; the driving device on the side-flipping lower template 5 is driven to one side of the connecting strip 41; the other side of the connecting strip 41 is fixed to the stamping block 42 by several clamping blocks 43; the end of the stamping block 42 away from the connecting strip 41 is adapted to be set in the stamping section 3; the driving device drives the connecting strip to move the stamping block to press the back panel at the side-flipping position, thereby performing side-flipping processing; the connecting strip and the stamping block can be disassembled and installed by clamping blocks, which is convenient to operate.

[0025] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
