Technical Field

[0001] This utility model relates to a shoe sole processing device, and more particularly to an EVA shoe sole cutting pattern processing device. Background Technology

[0002] Shoes are necessities, and people's demands for foot comfort have increased. The sole, as a crucial component of a shoe, is a key factor affecting wearing comfort, and its softness is a significant indicator of comfort. However, many existing soles are quite stiff, resulting in low comfort when worn. To improve sole comfort, some soles incorporate partitions during injection molding, creating bending grooves at the partitions. This process is relatively cumbersome. For example, patent application number 201610383490.7 discloses a biomimetic gripping and anti-slip sole with bending grooves. However, the bending grooves are quite wide, easily trapping stones and other foreign objects, affecting the sole's comfort. Summary of the Invention

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings.

[0017] Reference Figures 1-4 An EVA shoe sole cutting processing device includes an upper mold assembly 1, a lower mold assembly 2, and a vertical moving assembly 3. The upper mold assembly 1 includes a heating plate 11, a cutting template 12, and a pressure plate 13. The vertical moving assembly 3 is connected to the upper mold assembly 1. The lower mold assembly 2 is located below the upper mold assembly 1. The pressure plate 13 is located below the cutting template 12. The heating plate 11 is in close contact with the upper end of the cutting template 12. The pressure plate 13 and the cutting template 12 are both correspondingly arranged with the lower mold assembly 2. A cutting blade 16 is provided on the lower end face of the cutting template 12.

[0018] Specifically, when it is necessary to process the bottom of the shoe sole with knife-cut patterns, the shoe sole is upside down and fixed on the lower mold assembly 2, with the bottom surface of the shoe sole facing the upper mold assembly 1. After the shoe sole is fixed, the upper mold assembly 1 acts downward on the lower mold assembly 2, and the up-down moving assembly 3 pushes the upper mold assembly 1 downward, so that the cutting blade 16 on the cutting template 12 presses down and cuts knife-cut patterns on the shoe sole, completing the processing of the shoe sole with knife-cut patterns, so that the shoe sole can be bent in the corresponding direction along the knife-cut patterns.

[0019] Because of the heating plate 11, the cutting template 12 and the cutting blade 16 can be heated, so that the temperature of the cutting blade 16 is about 40°C higher than the melting point of the EVA sole. When the cutting blade 16 is pressed down quickly onto the sole, the contact part between the cutting blade 16 and the sole can melt to a certain extent. This causes the bottom of the cut to melt after the cutting blade 16 makes the cut, thus preventing the cut from deepening further during use.

[0020] The upper mold assembly 1 also includes a mounting plate 14 and an insulation layer 15, which are arranged closely from top to bottom. The insulation layer 15 uses existing glass fiber insulation material. By providing the insulation layer 15, the heat on the heating plate 11 can be effectively conducted to the lower cutting template 12 to heat the cutting blade 16, making it easier for the cutting blade 16 to press and cut grooves on the shoe sole, greatly reducing heat loss.

[0021] The lower mold assembly 2 includes a shoe mold 21 and a lower mold fixing plate 22. The shoe mold is set on the lower mold fixing plate 22. The shoe mold 21 is correspondingly set with the cutting template 12. That is, when the cutting template 12 moves downward, the cutting blade on the cutting template 12 can act on the shoe sole that is fixed upside down on the shoe mold 21.

[0022] To facilitate the installation of the shoe mold 21, an opening slot 221 is provided on the lower mold fixing plate 22. The shoe mold 21 is placed in the opening slot 221, and the adjusting screw 40 passes through the side wall of the opening slot 221 and abuts against the side wall of the shoe mold 21. Specifically, the adjusting screw 40 is located on both sides of the shoe mold 21, and the adjusting screw 40 is threadedly engaged with the lower mold fixing plate 22. By turning the adjusting screw 40, the shoe mold 21 can be pressed and fixed, and the position of the shoe mold 21 in the opening slot 221 can be adjusted, which facilitates the alignment of the sole and the cutting blade and ensures the cutting quality of the blade cut.

[0023] The upper mold assembly 1 also includes a panel 17, and a mounting plate 14 is fixed to the bottom of the panel 17 by bolts.

[0024] The upper mold assembly 1 also includes a pressure plate fixing plate 18, a guide rod 19 and a spring 20. The pressure plate fixing plate 18 is located below the die template 12. The pressure plate 13 is installed on the pressure plate fixing plate 18. One end of the guide rod 19 is sleeved on the panel 17 and the other end is fixed on the pressure plate fixing plate 18. The spring 20 is sleeved on the guide rod 19. One end of the spring 20 abuts against the panel 17 and the other end abuts against the pressure plate fixing plate 18.

[0025] In use, the EVA shoe sole cutting device of this utility model fixes the shoe sole upside down onto the shoe mold 21. Then, the upper mold assembly 1 is moved downward by the up-and-down moving component 3. When the upper mold assembly 1 moves downward, the pressure plate 13 first presses against the shoe sole. As the entire upper mold assembly 1 moves downward, the spring 20 is gradually compressed, the guide rod 19 extends out after passing through the panel 17, and the cutting blade 16 on the cutting template 12 continues downward, passing through the pressure plate 13 and acting on the shoe sole to cut the grooves. In actual use, to facilitate better action of the cutting blade 16 on the shoe sole, the pressure plate 13 is pressed against the front and rear ends of the shoe sole. The middle part of the pressure plate 13 has a hollow structure to facilitate the cutting blade 16 passing through the pressure plate 13 and cutting down on the shoe sole.

[0026] After the cutter 16 completes its downward cut, the up-and-down moving component 3 drives the upper mold component 1 upward, causing the cutter 16 to move upward and away from the sole. Simultaneously, under the rebound force of the spring 20, it acts downward on the pressure plate 13, ensuring the pressure plate 13 remains pressed firmly against the sole. This facilitates better separation of the cutter 16 from the sole and prevents the sole from moving upward with the cutter. As the entire upper mold component 1 continues to move upward, the pressure plate finally leaves the sole, allowing the sole to be easily removed from the shoe mold 21.

[0027] The pressure plate fixing plate 18 is provided with a mounting groove 181. The opening of the mounting groove 181 is located on the front side of the pressure plate fixing plate 18, and the pressure plate 13 is fixed in the mounting groove 181. The pressure plate fixing plate 18 is composed of two plates, upper and lower, which are locked together by bolts, forming the mounting groove 181 between the two plates. When the pressure plate 13 needs to be replaced according to the size of the shoe sole, the corresponding bolts are loosened to increase the distance between the two plates of the pressure plate fixing plate 18, making it easier to remove the original pressure plate 13. Then, a pressure plate that meets the usage requirements is replaced, inserted into the mounting groove 181, and the bolts are tightened to fix the pressure plate on the pressure plate fixing plate 18.

[0028] The vertical movement assembly 3 includes a vertical movement hydraulic cylinder 31, which is located above the upper mold assembly 1. The piston rod of the vertical movement hydraulic cylinder 31 is connected to the panel 17. By extending and retracting the piston rod of the vertical movement hydraulic cylinder 31, the entire upper mold assembly 1 can be moved vertically accordingly.

[0029] Heating tubes 5 are provided inside the heating plate 11. There are multiple heating tubes 5, which are evenly distributed inside the heating plate 11 to facilitate uniform heating of the heating plate 11 and meet the heating temperature requirements.

[0030] An EVA shoe sole cutting and texturing device further includes a front-to-back moving assembly 4, located below the lower mold assembly 2. The front-to-back moving assembly 4 includes a front-to-back moving hydraulic cylinder 41, the piston rod of which is connected to the lower mold fixing plate 22. Specifically, after the shoe sole is fixed to the shoe mold 21, the piston rod of the front-to-back moving hydraulic cylinder 41 moves the lower mold fixing plate 22 to one side of the upper mold assembly 1, so that the lower mold fixing plate 22 moves below the upper mold assembly 1, aligning the shoe sole with the cutter 16, facilitating the cutter 16 to cut the texturing downwards. Conversely, after the shoe sole has been cut, the upper mold assembly 1 moves upwards away from the shoe sole, and the front-to-back moving hydraulic cylinder 41 pushes the lower mold fixing plate 22 away from the upper mold assembly 1, making it convenient for the operator to remove the processed shoe sole and place the next shoe sole to be processed. This operation is convenient and improves operational safety.

[0031] The upper mold assembly 1 also includes two die fixing blocks 30, which are fixed to both sides of the heating plate 11. The inner side of each die fixing block 30 has a protrusion 301, and the top of the die template 12 engages with the protrusion 301. The die fixing blocks 30 are bolted to the heating plate 11. When it is necessary to change to a different stripe cutting blade 16, the bolts fixing the die fixing blocks 30 are loosened, increasing the distance between the two blocks and facilitating the removal of the die template 12. Then, the required die template 12 is inserted between the two protrusions 301, and the corresponding bolts are tightened to press and fix the die template 12, facilitating its fixation and replacement to meet different processing requirements.

[0032] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
