Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of sole processing, and particularly to a mold for sole processing. Background Art
[0002] A shoe is an item worn on the feet to prevent the feet from being injured. In the early stage of human civilization history, straw sandals and cloth shoes were more common. Nowadays, leather shoes and sports shoes are more common. In the manufacturing process of shoes, the pressing of the sole is indispensable to press and fix the sole to form it, so that the manufactured shoes are more durable.
[0003] For example, a mold for sole processing such as "CN117601340A" in the field of sole molds includes a lower mold, a pressing groove, an upper mold, a pressing die, an overflow groove, and pattern protrusions. The lower mold and the upper mold are hinged by a pin shaft. A number of pattern protrusions are set in a movable state. When the pressing die work is carried out, a number of pattern protrusions rise so that the work can proceed normally. When the demolding work is carried out, a number of pattern protrusions are hidden, so that the sole can be smoothly buckled on the pressing die and be lifted by the pressing die when the upper mold is opened, thus avoiding using other tools to take out the pressed sole in the pressing groove, avoiding pulling the sole, and avoiding damage to the sole. The demolding is very simple and convenient. At the same time, while hiding the pattern protrusions, the excess flash in the overflow groove, that is, the excess material, can be cut, so that secondary processing is not required, improving the work efficiency and the overall qualification rate.
[0004] However, in the prior art, as shown in the above patent, an ejector block that can move up and down is adopted. Through the lifting movement of the ejector block, the sole is evenly demolded from the mold. Although this method avoids directly pulling the sole, the ejection method is that all the pattern protrusions move up and down together. For soft materials, only the pattern part may be ejected, and it is difficult to separate the sole from the mold. Moreover, if the local pattern of the sole is particularly deep or complex, this solution is difficult to ensure uniform demolding in all areas, and the pattern may still be stuck, affecting the demolding effect. Summary of the Invention
[0005] In view of the above existing problems, the present invention is proposed.
[0006] The purpose of the present invention is to solve the problems that in the prior art, when dealing with soles with deep groove patterns, soft materials or complex structures, there may still be phenomena such as incomplete demolding and sole damage.
[0007] To solve the above technical problems, the present invention provides the following technical solutions:
[0008] On the one hand, the present invention provides a mold for sole processing, which includes an upper mold and a lower mold. A mold groove is provided above the lower mold, and a pressing block adapted to the mold groove is provided below the upper mold. An assembly groove is provided inside the lower mold, and the assembly groove is communicated with the mold groove through a printing groove above. A printing block is hermetically slidably arranged in the printing groove. A support shaft is provided below the printing block. A push bar is slidably arranged below the assembly groove. Both sides of the push bar are provided with inclined surfaces. A handle is provided at one end of the push bar. A flexible film is laid in the mold groove, and the upper part of the flexible film is used to place sole raw materials. An air pump is provided outside the lower mold. An air groove is communicated inside the support shaft and the printing block. A plurality of side grooves communicated with the air groove are provided on the side wall below the printing block. The upper side grooves of the support shaft in the state above the push bar are located in the mold groove, and the air groove is supplied with air by the air pump.
[0009] Further, a fixed seat is provided in the middle and lower part of the outer wall of the support shaft. Both sides of the fixed seat are hinged to the upper part inside the lower mold through telescopic shafts. A first spring is sleeved outside the telescopic shafts. By providing the fixed seat and the first spring, the first spring pushes the fixed seat downward, so that the lower end of the support shaft in the initial state is closely attached to the lower part inside the assembly groove of the lower mold, ensuring the dimensional accuracy when the upper mold and the lower mold cooperate to hot-press the inner rubber sole.
[0010] Further, a sealing frame is provided on the lower mold above the assembly groove. All the printing grooves are located directly above the sealing frame. The lower end of the support shaft slidably penetrates through the sealing frame and extends downward. The fixed seat is located above the sealing frame. The output end of the air pump extends into the assembly groove above the sealing frame. The lower end of the air groove extends outside the side wall of the support shaft. The air pump is a two-way pump body. When unloading, gas is filled below the flexible film, and the flexible film is unfolded to promote the separation between the sole and the lower mold. On the contrary, after unloading is completed, the gas below the flexible film can be discharged, so that the flexible film is closely attached to the surfaces of the lower mold and the printing block.
[0011] Further, a plurality of side grooves are evenly provided. One end of the side groove communicated with the outside is rotatably provided with a cover plate through a torsion spring. The edge of the cover plate is hermetically slidably arranged on the inner wall of the side groove. By providing the cover plate, the situation of gas entering below the flexible film during the hot-pressing process can be avoided.
[0012] Further, both sides of the lower end of the support shaft are arc-shaped, and each support shaft is of equal length. The height of the printing block is higher than twice the thickness of the printing groove. By setting both sides of the bottom end of the support shaft to be arc-shaped, it is convenient for the push bar to lift the support shaft when passing through the bottom of the support shaft.
[0013] Further, a limiting groove is provided above one side of the pushing bar. A flap is rotatably provided in the limiting groove through a rotating shaft. The upper end of the flap is higher than the height above the pushing bar when the flap is in a state of fitting with the upper part of the pushing bar. By providing the flap, when the pushing bar moves for the first time, the lower end of the support shaft passes through the side of the pushing bar without the flap. At this time, the highest point after the support shaft is lifted is the highest point of the pushing bar. When the pushing bar moves from one end of the assembly groove to the other end and then moves in the reverse direction, the lower end of the support shaft needs to pass through the side of the pushing bar with the flap. When passing through the flap, the side of the support shaft will push the flap upward to flip until the flap rotates above the rotating shaft. At this time, the upper end of the flap is higher than the upper end of the pushing bar. When the support shaft passes through the flap, it needs to be lifted to a higher position. At this time, the printed block will push the formed sole to a higher position, so that the sole can be better demolded from the lower mold. By the reciprocating movement of the pushing bar, the support shaft can be gradually lifted a little height in sequence. When moving for the second time, more air can be injected between the sole and the lower mold, achieving a better and more complete demolding effect.
[0014] Further, sliding rails are symmetrically provided on both sides of the lower mold in the assembly groove. Sliders are slidably provided on the sliding rails. Both ends of the pushing bar are assembled and connected with the sliders. By pulling the pushing bar, the sliders can slide on the sliding rails, making the movement of the pushing bar more stable.
[0015] Further, a strip-shaped groove is provided on the side wall of the lower mold. The strip-shaped groove is located at one of the sliding rails. A connecting shaft is provided on the corresponding slider. One end of the connecting shaft slidably penetrates through the sliding rail and the strip-shaped groove and extends outside. The handle is assembled and connected with the outer end of the connecting shaft arranged outside. By sliding the handle, the pushing bar can be driven to move smoothly in the assembly groove, realizing the operation of lifting the support shaft.
[0016] Further, an installation groove is provided above the inner wall of the lower mold at the mold groove. A clamping strip is slidably clamped in the installation groove. The upper end of the flexible film is arranged between the installation groove and the clamping strip. By providing the clamping strip, the flexible film can be replaced when it is damaged.
[0017] Further, a protrusion is provided on the inner side of the clamping strip. A clamping groove adapted to the protrusion is provided on the inner side of the lower mold. Through the clamping and limiting of the protrusion and the clamping groove, the stability of the installation of the flexible film is ensured.
[0018] The beneficial effects of the present invention are as follows:
[0019] 1. In the present invention, by pulling the handle, the push bar is driven to slide smoothly at the bottom of the assembly groove. During the sliding process, the support shafts passed by the push bar are lifted by the sliding, and the lifting height is the height of the push bar. The elevation of the support shafts causes the upper printing blocks to be lifted, thereby lifting the flexible film and a part of the upper sole above by a certain distance, creating a gap between the sole and the lower mold. When the printing blocks move upward, the side grooves on their sides are gradually exposed inside the lower mold. The air pump is driven to inflate the space in the assembly groove above the sealing frame, and the gas enters the side grooves upward through the lower end of the air groove. The air flow pushes open the cover plate and enters the space below the flexible film. Through continuous filling of the gas, the creases of the flexible film can be gradually unfolded, further separating the sole from the flexible film by propping up the sole.
[0020] 2. In the present invention, the push bar moves from one end of the sole to the other end, separating each part of the sole from the lower mold by a certain distance, and the lifting height of each printing block is not too high, avoiding the situation of printing tearing caused by excessive lifting at one time. After one movement is completed, a reverse movement is carried out. During the reverse movement, the support shaft rotates and unfolds the flap on the push bar. When the support shaft passes through the flap, it can be lifted to a higher height, resulting in a better separation effect.
[0021] 3. In the present invention, through the provided fixed seat and the first spring, the first spring pushes the fixed seat downward, making the lower end of the support shaft in the initial state closely attached to the lower part inside the lower mold in the assembly groove, ensuring the dimensional accuracy when the upper mold and the lower mold cooperate to hot-press the internal rubber sole.
[0022] 4. In the present invention, through the provided engaging strip, the flexible film can be replaced when it is damaged. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners
[0034] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.
[0035] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.
[0036] Secondly, as used herein, "one embodiment" or "an embodiment" refers to a specific feature, structure or characteristic that may be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.
[0037] Please refer to Figures 1-8The present invention provides a technical solution: a mold for processing a shoe sole, comprising an upper mold 1 and a lower mold 2, wherein a mold groove 3 is provided above the lower mold 2, a pressing block 4 adapted to the mold groove 3 is provided below the upper mold 1, an assembly groove 5 is provided inside the lower mold 2, the assembly groove 5 is connected to the mold groove 3 through a printing groove 6 above, a printing block 711 is provided in the printing groove 6 for sealing and sliding, a support shaft 712 is provided below the printing block 711, a push strip 713 is provided for sliding at the lower part of the assembly groove 5, and both sides of the push strip 713 are inclined surfaces. A handle 714 is provided at one end of the push strip 713, a flexible film 715 is laid in the mold groove 3, and the sole material is placed above the flexible film 715. An air pump 716 is provided on the outside of the lower mold 2. The support shaft 712 and the printed pattern block 711 are connected to each other and are provided with an air groove 717. The side wall below the printed pattern block 711 is provided with a plurality of side grooves 718 connected to the air groove 717. The support shaft 712 located above the push strip 713 has its upper end side groove 718 in the mold groove 3, and the air groove 717 is supplied with air through the air pump 716.
[0038] like Figures 1-8 As shown, a fixed seat 811 is provided in the middle and lower part of the outer wall of the support shaft 712, and the two sides of the fixed seat 811 are hinged to the upper part of the lower mold 2 through the telescopic shaft 812. The outer part of the telescopic shaft 812 is sleeved with a first spring 813. Through the set fixed seat 811 and the first spring 813, the first spring 813 pushes the fixed seat 811 downward, so that the lower end of the support shaft 712 in the initial state is tightly attached to the lower part of the lower mold 2 in the assembly groove 5, thereby ensuring the dimensional accuracy of the upper mold 1 and the lower mold 2 when hot pressing the internal rubber sole.
[0039] like Figures 1-8 As shown, a sealing frame 9 is provided on the lower mold 2 above the assembly groove 5, all the printing grooves 6 are located directly above the sealing frame 9, the lower end of the support shaft 712 slides through the sealing frame 9 and extends to the bottom, the fixed seat 811 is located above the sealing frame 9, the output end of the air pump 716 extends to the assembly groove 5 above the sealing frame 9, and the lower end of the air groove 717 extends to the outside of the side wall of the support shaft 712. The air pump 716 is a bidirectional pump body. During unloading, gas is filled under the flexible membrane 715, and the flexible membrane 715 is unfolded to separate the sole from the lower mold 2. Conversely, after the unloading is completed, the gas under the flexible membrane 715 can be discharged, so that the flexible membrane 715 is tightly fitted to the surface of the lower mold 2 and the printing block 711.
[0040] like Figures 1-8 As shown, a plurality of side grooves 718 are evenly arranged, and a cover plate 10 is provided at one end of the side groove 718 which is connected to the outside and is rotatably provided with a torsion spring. The edge of the cover plate 10 is sealed and slidably arranged with the inner wall of the side groove 718. The set cover plate 10 can prevent gas from entering under the flexible membrane 715 during the hot pressing process.
[0041] like Figures 1-8As shown, both sides of the lower end of the support shaft 712 are arc-shaped, and each support shaft 712 is of equal length. The height of the printing block 711 is higher than twice the thickness of the printing groove 6. By setting both sides of the bottom end of the support shaft 712 as arc-shaped, it is convenient for the push bar 713 to lift the support shaft 712 when passing through the bottom of the support shaft 712.
[0042] As Figures 1-8 shown, a limiting groove 111 is provided above one side of the push bar 713. A flap 113 is rotatably provided in the limiting groove 111 through a rotating shaft 112. When the flap 113 is in a state of being attached to the upper part of the push bar 713, the upper end of the flap 113 is higher than the upper height of the push bar 713. By providing the flap 113, when the push bar 713 moves for the first time, the lower end of the support shaft 712 passes through the side of the push bar 713 where the flap 113 is not provided. At this time, the highest point of the support shaft 712 after being lifted is the highest point of the push bar 713. When the push bar 713 moves from one end to the other end in the assembly groove 5 and then moves in the reverse direction, the lower end of the support shaft 712 needs to pass through the side of the push bar 713 where the flap 113 is provided. When passing through the flap 113, the side of the support shaft 712 will push the flap 113 upward until the flap 113 rotates around the rotating shaft 112 to the upper side. At this time, the upper end of the flap 113 is higher than the upper end of the push bar 713. When the support shaft 712 passes through the flap 113, it needs to be lifted to a higher position. At this time, the printing block 711 will push the formed sole to a higher position, so that the sole can be better demolded from the lower mold 2. Through the reciprocating movement of the push bar 713, the support shaft 712 can be gradually lifted a little height in sequence. When moving for the second time, more air can be injected between the sole and the lower mold 2, achieving a better and more complete demolding effect.
[0043] As Figures 1-8 shown, slide rails 121 are symmetrically provided on both sides of the lower mold 2 in the assembly groove 5. Sliders 122 are slidably provided on the slide rails 121. Both ends of the push bar 713 are assembled and connected to the sliders 122. By pulling the push bar 713, the sliders 122 can be slid on the slide rails 121, making the movement of the push bar 713 more stable.
[0044] As Figures 1-8 shown, a strip-shaped groove 131 is formed on the side wall of the lower mold 2. The strip-shaped groove 131 is located at one slide rail 121. A connecting shaft 132 is provided on the corresponding slider 122. One end of the connecting shaft 132 slidably penetrates through the slide rail 121 and the strip-shaped groove 131 and extends outside. A handle 714 is assembled and connected to the outer end of the connecting shaft 132 provided outside. By sliding the handle 714, the push bar 713 can be driven to move smoothly in the assembly groove 5, realizing the operation of lifting the support shaft 712.
[0045] As Figures 1-8As shown, an installation groove 141 is formed above the inner wall of the lower mold 2 at the mold groove 3. A clamping strip 142 is slidably clamped in the installation groove 141. The upper end of the flexible film 715 is arranged between the installation groove 141 and the clamping strip 142. By means of the arranged clamping strip 142, the flexible film 715 can be replaced when it is damaged.
[0046] As Figures 1-8 shown, a protruding strip 143 is arranged on the inner side of the clamping strip 142, and a clamping groove 144 which is clamped and matched with the protruding strip 143 is arranged on the inner side of the lower mold 2. Through the clamping and limiting of the protruding strip 143 and the clamping groove 144, the stability of the installation of the flexible film 715 is ensured.
[0047] Working principle: When processing the sole, the rubber sheet of the sole raw material is placed into the mold groove 3 above the flexible film 715, and then the upper mold 1 and the lower mold 2 are covered and hot-pressed into shape. After the upper mold 1 and the lower mold 2 are separated, the formed sole is unloaded. Specifically, by pulling the handle 714, the pushing strip 713 is driven to slide smoothly at the bottom of the assembly groove 5. During the sliding process, the support shaft 712 passed by the pushing strip 713 is lifted by sliding, and the lifted height is the height of the pushing strip 713. The lifting of the support shaft 712 causes the printing block 711 above to be lifted, and then the flexible film 715 and the upper part of the sole are lifted by a certain distance, so that a gap is generated between the sole and the lower mold 2. When the printing block 711 moves upward, the side groove 718 on its side is gradually exposed in the lower mold 2. The air pump 716 drives air to be filled into the space of the assembly groove 5 above the sealing frame 9. The gas enters the side groove 718 upward through the lower end of the air groove 717, and the air flow pushes open the cover plate 10 and enters the space below the flexible film 715. Through the continuous filling of the gas, the creases of the flexible film 715 can be gradually unfolded, so as to further support the sole and separate it from the flexible film 715. Among them, the pushing strip 713 moves from one end of the sole to the other end, and a little distance can be separated between each part of the sole and the lower mold 2, and the lifted height of each printing block 711 is not too high to avoid the situation of printing tearing caused by one-time lifting too high. After one movement is completed, a reverse movement is carried out. When moving in the reverse direction, the support shaft 712 will rotate and unfold the flap 113 on the pushing strip 713. When the support shaft 712 passes through the flap 113, it can be lifted to a higher height, so that the separation effect is better. Through the lifting of the support shaft 712 and the filling of gas into the flexible film 715, the separation between the sole and the lower mold 2 can be promoted faster and more safely, effectively ensuring the integrity of the product. Among them, the material of the flexible film 715 can be high-temperature resistant silicone rubber, and its temperature resistance range is -60°C to 250°C. Some special silicone rubbers can reach 300°C. It has extremely strong flexibility, can adapt to complex patterns and concave-convex surfaces, has good wear resistance, is non-toxic, has good tear resistance, and can be used repeatedly.
[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
