The upper die matches and corresponds to the lower die, and each end corner of the upper die has several threaded holes, which are fixedly connected to the upper part of the cold setting machine by matching nuts. In use, after the shoe insole is stamped, due to pressure and the characteristics of the material, it often sticks to the cavity of the lower die. Workers usually need to pry the insole with their fingers to remove it from the cavity. This method is not only inconvenient but also easily damages the edges of the insole, affecting the product's appearance quality.

[0003] Therefore, it is necessary to propose a shoe insole stamping die to solve the above problems. Utility Model Content

[0004] Technical problem to be solved: The purpose of this utility model is to provide a shoe insole stamping mold to solve the problem mentioned in the background art of existing shoe insole stamping molds. After the shoe insole is stamped, due to the pressure and the characteristics of the material, it often sticks to the mold cavity of the lower mold. Workers usually need to use their fingers to pry the shoe insole to remove it from the mold cavity. This method is not only inconvenient to operate, but also easily leads to damage to the edge of the shoe insole, affecting the appearance quality of the product.

[0005] Technical Solution: To achieve the above objectives, this utility model is implemented through the following technical solution: A shoe insole stamping die includes an upper die and a lower die. The bottom of the upper die is detachably equipped with a stamping boss. The lower die cavity is provided with an ejector assembly, which includes a top plate disposed in and adapted to the cavity, and a piston cavity opened in the lower die. A piston II is axially slidably fitted inside the piston cavity. A spring is provided on the inner side of the piston II, and a push rod is fixedly installed on the outer side. The other end of the push rod passes through the lower die and is fixedly installed with a push plate. Piston holes are vertically opened at both the front and rear ends of the bottom of the cavity. Multiple piston holes are connected to the end of the piston cavity away from the push plate. A piston I is slidably fitted vertically inside the piston holes. A connecting rod is fixedly installed on the top of the piston I. The upper ends of multiple connecting rods are respectively fixedly connected to the corresponding top plates.

[0006] Preferably, the lower mold includes template I, template II bolted to the bottom of template I, and a sealing gasket disposed between template I and template II. The mold cavity is opened at the top of template I, and the piston cavity is horizontally opened inside template I.

First, the upper die and the lower die need to be installed on a stamping machine, and the formed insole is placed in the die cavity. The stamping machine controls the upper die to press down, and the die pressing boss stamps and forms the insole, so that corresponding patterns are pressed on the upper surface of the insole. After forming, when the upper die and the lower die are separated, press the push plate. The push plate drives the piston II to move through the push rod. The piston II slides in the piston cavity, and the gas in the piston cavity is input into the plurality of piston holes. Under the action of air pressure, the piston I in the piston hole moves upward, and then pushes the top plate to push the insole out of the die cavity, which is convenient for the staff to take out.

[0010] By arranging the ejection component, the insole stamping die effectively solves the problem that the insole adheres to the lower die cavity after stamping and forming in the prior art and is difficult to take out, and greatly improves the production efficiency and the product qualification rate.

[0017] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0018] Embodiment 1: Embodiment 1 of the present invention provides an insole stamping die, which is directly improved on the existing insole stamping die and has a unique structure. Please refer to Figure 1-5 As shown, it includes an upper die 1 and a lower die 2. A stamping die boss is detachably installed at the bottom of the upper die 1 (not shown in the figure), and its shape can be flexibly adjusted according to needs. There are various connection methods between the stamping die boss and the upper die 1, such as: bolt connection. An ejection component is provided in the die cavity 24 of the lower die 2. The ejection component includes a top plate 25 provided in the die cavity 24 and adapted to it, and further includes a piston cavity 29 opened in the lower die 2. A piston II 210 is slidably sleeved along the axial direction inside the piston cavity 29. A spring 211 is provided inside the piston II 210, and a push rod 212 is fixedly installed on the outside. The other end of the push rod 212 penetrates through the lower die 2 and is fixedly installed with a push plate 213. Piston holes 26 are vertically opened at both the front and rear ends of the bottom of the die cavity 24. The plurality of piston holes 26 are all communicated with one end of the piston cavity 29 away from the push plate 213. A piston I 28 is slidably sleeved along the vertical direction inside the piston hole 26. A connecting rod 27 is fixedly installed at the top of the piston I 28. The upper ends of the plurality of connecting rods 27 are respectively fixedly connected to the corresponding top plates 25.

[0019] The lower die 2 includes a template I 21, a template II 22 bolted to the bottom of the template I 21, and a gasket 23 provided between the template I 21 and the template II 22. The die cavity 24 is opened at the top of the template I 21, and the piston cavity 29 is horizontally opened in the template I 21. A communication hole 215 is opened at the bottom of the piston cavity 29 and communicated with it. "Soil"-shaped communication grooves 216 are opened at the tops of the template II 22 and the gasket 23, and the communication groove 216 on the gasket 23 penetrates through the gasket 23. The communication hole 215 and the lower ends of the plurality of piston holes 26 are all communicated with the communication groove 216. One end of the piston cavity 29 away from the spring 211 is open, and a cover plate 214 is bolted in the opening. A through hole for the push rod 212 to insert is opened on the cover plate 214.

[0020] Working principle: When using this mold, the upper mold 1 and lower mold 2 are first installed on the stamping machine. Then, the formed insole is placed in the mold cavity 24. The stamping machine controls the upper mold 1 to press down, and the pressing boss presses down on the insole, pressing the corresponding pattern onto the upper surface of the insole. After the upper mold 1 and lower mold 2 separate, the push plate 213 is pressed down. The push plate 213 pushes the piston II 210 to move through the push rod 212, thereby inputting the gas in the piston cavity 29 into multiple piston holes 26. At this time, the gas in the piston holes 26... Piston I 28 moves upward under air pressure, which in turn pushes top plate 25 to push the insole out of mold cavity 24, making it easier for workers to remove the stamped insole from mold cavity 24 and improving processing speed. After the workers remove the insole, push plate 213 can be released. At this time, piston II 210 returns to its initial position under the action of spring 211, and top plate 25 and piston I 28 also return to their initial positions under air pressure. At this time, the next pair of insoles can be placed into mold cavity 24 for stamping.

[0021] Example 2: The difference between Example 2 and Example 1 is that the push rod 212 is threadedly connected to the push plate 213. The threaded connection between the push rod 212 and the push plate 213 facilitates the assembly of the mold.
