DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-2The utility model provides a technical solution for an automatic folding and leather pasting mold for a product: the automatic folding and leather pasting mold for a product comprises an upper mold component 3 for fixing the product, a lower mold component 1 for flanging the leather is arranged below the upper mold component 3, and four groups of folding components 2 for folding and hot pressing the leather after flanging are installed on the top of the lower mold component 1, and the four groups of folding components 2 are distributed in a rectangular shape.

[0019] It should be noted that the lower mold assembly 1 is fixed to the base of the hot press, and the upper mold assembly 3 is fixed to the driving end of the lifting device of the hot press;

[0020] By fixing the leather-bonded product at the bottom of the upper mold assembly 3, the upper mold assembly 3 and the product are driven downward by the lifting device, so that the product and the leather enter the interior of the lower mold assembly 1, and then the edge of the leather is flipped 90° around the product, and then the four groups of folding assemblies 2 push and press the flipped leather edge toward the middle to perform PU folding and hot pressing bonding, thereby realizing automatic folding operation. After the folding is completed, the four groups of folding assemblies 2 are reset, and the lifting device drives the upper mold assembly 3 and the product to move upward.

[0021] See also Figure 3 The lower mold assembly 1 includes a lower mold base 11, a boss 12 is installed at the top center of the lower mold base 11, a groove 13 is opened at the top of the boss 12, the size of the groove 13 is slightly larger than the product size, and slightly smaller than the leather size, the side of the lower mold base 11 and the position corresponding to the groove 13 are opened with installation grooves 14, and the top corners of the lower mold base 11 are installed with limiting columns 15.

[0022] It should be noted that when the upper mold assembly 3, the product and the leather are pressed downward, the center of the product and the leather enters the groove 13, and the edge of the leather is turned 90° around the product according to the size of the groove 13.
