Description

TECHNICAL FIELD

[0001] The utility model relates to the mould field especially relates to a shoemaking mould and shoes manufactured with the mould. BACKGROUND

[0002] Currently, shoemaking moulds are mainly used for producing shoe soles and auxiliary parts of shoe uppers. For shoe soles, there are mainly two types of moulds. One is single-piece mould, which is usually composed of upper and lower parts, i.e. upper mould and lower mould. In injection molding, die casting and other processes, the upper mould and the lower mould form the upper and lower surfaces of the shoe sole respectively. The other is multi-piece combined mould. For complex shoe sole design, the mould may be composed of multiple parts, each part corresponding to a different area of the shoe sole, such as the heel, the front part of the shoe, the insole, etc. Different parts of the mould can be processed independently and then assembled to form the final shoe sole. Different mould types and manufacturing processes are adopted according to different shoe sole materials, such as rubber, EVA (ethylene-vinyl acetate copolymer) or PU (polyurethane).

[0003] The technical limitations of traditional shoemaking moulds are as follows. First, the process is complicated. Traditional moulds can usually only make one part of the shoe. The shoe sole and the shoe upper need to be made separately and then assembled, which increases the complexity and time cost of the production process. Second, the cost is high. Since multiple moulds are needed to complete the production of a pair of shoes, the manufacturing and maintenance costs of the moulds are high.

[0004] In the existing shoemaking mould technology, most moulds are mainly used for making shoe soles and some accessories, while moulds that can realize the integrated molding of shoe soles and shoe uppers are relatively few. This limitation makes the traditional shoemaking process rely on a multi-step production process, increasing the manufacturing complexity and time cost. Developing a new type of mould that can realize the integrated molding of shoe soles and shoe uppers not only can simplify the production process, but also can improve efficiency and reduce cost, while supporting more complex footwear design and material application.

[0005] In summary, the existing shoemaking mould technology mainly faces problems such as complex production process, high cost, design limitation and poor material compatibility. In order to improve the efficiency and flexibility of shoemaking production, developing a mould that can simultaneously form shoe soles and shoe uppers will become an important direction for the development of future shoemaking mould technology.

[0037] It can be understood that the structure of the first last 520 and the second last 530 being symmetrically arranged on both sides of the rod body in the embodiment is a preferred scheme. The overall structure of the mold arranged according to the structure is symmetrical, which facilitates taking out the formed shoes respectively, and the overall equipment is small in size and easy to operate. Those skilled in the art can arrange the first last 520 and the second last 530 on the same side of the connecting rod according to actual needs. The shoe top is connected with the connecting rod, and the effect of simultaneously manufacturing a pair of sole and upper integrally formed shoes can also be achieved.

[0038] Further, the width of the first end and the second end of the connecting assembly 510 gradually decreases from the two sides to the rod body, so that the connecting assembly 510 has a structure of being wide at both ends and narrow in the middle. The first end and the second end are fixed between the clamping blocks of the first mold 100 and the second mold 200, so as to avoid the deviation of the connecting assembly 510 in the first axis direction. Meanwhile, a clamping groove is arranged on the surface of the rod body opposite to the first mold 100, and cooperates with the protrusion on the first mold 100 to form a clamping structure, which is used to avoid the position deviation of the connecting assembly 510 in the mold after the mold is closed, and to avoid damage to the mold.

[0039] The first end of the movable inner core 500 is outwardly protrudingly provided with a pulling part, and the second end is provided with a third hinge structure 540. The hinge structure has the same size as the hinge structure on the first mold 100 and the second mold 200. The hinge structures are arranged in series along the third axis, so as to form a movable pivot connection structure between the first mold 100, the second mold 200 and the movable inner core 500. The pulling part at the first end of the connecting assembly 510 is convenient for an operator to hold one end of the movable inner core 500 to rotate or disassemble it around the hinge structure. The pulling part in the embodiment is provided as a ring body, which is convenient for the hand to hold.

[0040] At least one guide hole 550 penetrating along the second axis is arranged on the connecting assembly 510 of the movable inner core 500. Two guide holes 550 are arranged in the embodiment. The guide hole cooperates with the positioning column on the mold, so as to facilitate the positioning and fixing of the movable inner core 500 with the first mold 100 and the second mold 200. It can be understood that the guide hole 550 can also be arranged on the mold, and the corresponding positioning column is arranged on the connecting assembly 510, as long as the effect of positioning and fixing the connecting assembly 510 with the first mold 100 and the second mold 200 can be achieved.

[0041] As Figure 3 and Figure 4As shown, the third mold 300 and the fourth mold 400 are in the form of a long cuboid structure, symmetrically arranged on the front and back sides of the connecting assembly 510, and the third mold cavity and the fourth mold cavity on the inner side are respectively arranged opposite to the first shoe last bottom and the second shoe last bottom, and the bottom mold embryo placed in the mold cavity can be foamed to form a sole structure, the bottom of the third mold 300 and the fourth mold 400 is formed with a strip-shaped flange 410, which is symmetrically arranged on the bottom of the left and right sides of the mold, and cooperates with the groove structure on the second mold 200 to form a clamping structure, so that the third mold 300 and the fourth mold 400 can be stably axially moved along the third axis to perform mold closing or mold opening, and the mold reaches a tightly closed state under the pressure of the machine platform, so as to reach the design appearance and thickness standard of the shoe product. The clamping structure is arranged on the bottom of the third mold and the bottom of the fourth mold, and is arranged in close contact with the second mold by means of the bottom wall of the mold, so as to quickly align the clamping structure of the mold bottom, improve the assembly efficiency, and improve the sealing performance.

[0042] It can be understood that the positions of the flange 410 and the groove structure in the clamping structure described above can be interchanged, that is, the flange 410 is arranged on the second mold 200, and the groove is arranged on the bottom of the third mold 300 and the fourth mold 400, as long as the third mold 300 and the fourth mold 400 can be stably axially moved along the third axis to perform mold closing or mold opening.

[0043] It should be noted that the third mold 300 and the fourth mold 400 can also be arranged in a pivoted manner, as long as the effect of closing the third mold 300 and the fourth mold 400 can be achieved, that is, the right end of the third mold 300 and the fourth mold 400 is connected to the right end of the first mold 100 or the second mold 200 through a hinge, and the hinge is turned inward to close the mold.

[0044] Further, the inner side opposite to the mold cavity in the third mold 300 and the fourth mold 400 is a third outer wall and a fourth outer wall, and the distance between the outer wall and the connecting assembly 510 gradually increases from top to bottom, so that the outer wall is arranged in an inclined manner. The purpose of arranging this structure is that when the first mold 100 is closed downward to close the mold, the downward pressure is decomposed into a part of pressure directed to the direction of the movable inner wall 500 through the inclined side wall, so as to extrude the third mold 300 and the fourth mold 400 to continue the movement in the direction of closing the mold under the guidance of the clamping structure, and at the same time, the tightness of the mold is enhanced to prevent the material in the mold cavity from overflowing.

[0045] Preferably, the first included angle between the third outer wall, the fourth outer wall and the second axis is 20 degrees to 45 degrees. If the included angle is less than this, the relative pressure formed is too small, which is not conducive to the inward sliding of the third mold 300 and the fourth mold 400. If the included angle is greater than this, the downward closing of the first mold 100 will be resisted by a relatively large force.

[0046] The bottom of the third mold 300 and the fourth mold 400 is provided with a guide groove 420 that is opened in the third axis direction. The guide groove 420 corresponds to the protruding ribs provided on the inner side surface of the first mold 100 and the second mold 200, so as to facilitate the guiding and fixing of the third mold 300 and the fourth mold 400 when they slide along the third axis. At the same time, the bottom of the third outer wall and the fourth outer wall is provided with a lifting part 430 that is outwardly arranged, which is used to pull out and insert the third mold 300 and the fourth mold 400 to slide. In the embodiment, the lifting part is arranged as a ring body, which is convenient for the hand to hold.

[0047] As shown in FIG. 1, Figure 5 The first mold 100 and the second mold 200 are symmetrically arranged on the upper and lower sides of the movable inner core 500 and have a flat cuboid structure. The first mold cavity 101 and the second mold cavity 201 on the inner side surface correspond to the two sides of the first shoe last surface and the second shoe last surface, respectively. The shoe upper sub-embryo placed in the mold cavity can be foamed to form a shoe upper structure. Since one side of the first mold cavity 101 and the second mold cavity 201 is connected with the third mold cavity 301, and the other side of the first mold cavity 101 and the second mold cavity 201 is connected with the fourth mold cavity 401, a pair of shoes with a foamed shoe sole and shoe upper structure can be directly formed.

[0048] Further, the first side block 102 and the second side block 103 are respectively arranged on the front side and the rear side of the first mold 100 and extend downward. The inner side surface of the first side block 102 is a first inner wall, and the inner side surface of the second side block 103 is a second inner wall. After the third mold 300 and the fourth mold 400 are closed, the first side block 102 of the first mold 100 is located on the outer side of the third mold 300, so that the first inner wall is opposite to the third outer wall. The second side block 103 of the first mold 100 is located on the outer side of the fourth mold 400, so that the second inner wall is opposite to the fourth outer wall. The distance between the first inner wall and the second inner wall and the connecting assembly 510 gradually increases from top to bottom, so that the outer wall is arranged in a whole inclined manner and has a second included angle with the second axis. It can be understood that the second included angle has the same degree as the first included angle. When the first mold 100 is closed downward, the first inner wall and the second inner wall form a downward pressure on the third outer wall and the fourth outer wall, respectively. Through the inclined arrangement of the inner wall and the outer wall, the downward pressure is decomposed into a part of inward pressure, which pushes the third mold 300 and the fourth mold 400 to further slide inward, improves the overall tightness of the mold, and avoids material overflow.

[0049] The right side of the first mold 100 and the second mold 200 is provided with a first hinge structure 104 and a second hinge structure 105, so that the first mold 100 and the second mold 200 are pivotally connected, so that the first mold 100 rotates around the hinge structure, and the interval between the two can accommodate the third hinge structure 540, and then the right side of the movable inner core 500 is pivotally connected to the right side of the first mold 100 and the second mold 200 for fixation. It can be understood that the hinge structure can also be provided as a sliding structure, a gas pressure and a hydraulic structure, as long as it can realize the pivotal connection effect between the first mold 100, the second mold 200 and the movable inner core 500.

[0050] A group of locking structures are arranged on the left side of the first mold 100 and the second mold 200, which are used to lock and fix the first mold 100 and the second mold 200 after closing. Specifically, a wedge-shaped protrusion 202 is arranged on the left side of the second mold 200, and a plate-shaped buckle plate 106 is arranged at the corresponding position on the left side of the first mold 100. The bottom of the buckle plate 106 is provided with a wedge-shaped buckle strip, which is clamped with the wedge-shaped protrusion 202 to complete the locking of the first mold 100 and the second mold 200. It can be understood that the positions of the two can also be transposed, or other hooking or other forms of locking structure can be used. The person skilled in the art can select according to the actual situation.

[0051] Further, the left side of the first mold 100 and the second mold 200 is provided with a lifting part 203, which is used to lift or rotate the first mold 100 and the second mold 200. The lifting part in the embodiment is provided as a ring body, which is convenient for hand holding. The person skilled in the art can select a rod or other structure as the lifting part according to the actual needs.

[0052] A group of clamping blocks are arranged on the left and right ends of the first mold 100 and the second mold 200, and the clamping blocks are kept apart from each other. The width of the interval region gradually decreases from outside to inside, and the shape of the two ends of the connecting rod of the movable inner core 500 is matched, so as to accommodate the two ends of the connecting rod and clamp them, so that the movable inner core 500 remains in a stable state after the first mold 100 and the second mold 200 are closed.

[0053] The two positioning columns 204 are arranged in the middle of the first mold 100 and the second mold 200, and the arrangement positions correspond to the positions of the two guide holes of the movable inner core 500, the guide holes are matched with the positioning columns 204 on the mold, so that the movable inner core 500 is positioned and fixed with the first mold 100 and the second mold 200. It can be understood that the positioning columns 205 and the guide hole structures 206 are correspondingly arranged on the opposite inner cavity surfaces of the first mold 100 and the second mold 200, so as to realize the rapid positioning and stability of the first mold 100 and the second mold 200, and improve the tightness of the mold. In the embodiment, the positioning columns and the guide hole structures are arranged on the left side of the first mold 100 and the second mold 200, so as to enhance the connection stability of the side away from the hinge structure, and improve the stability and tightness of the mold as a whole.

[0054] In use, the upper and the sole embryo are arranged in the shoe tree and the third mold 300 and the fourth mold 400. The first mold 100 and the fourth mold 400 are opened, the movable inner core 500 with the embryo is positioned with the first mold 100 through the guide column and is embedded in the second cavity 201 of the second mold 200, the third mold 300 and the fourth mold 400 with the bottom mold embryo on the two sides are pushed into the second mold 200 along the flange 410 and the guide groove 420, and finally the first mold 100 is tightly covered to complete the locking of the buckle, so that a closed embryo foaming cabin is formed in the mold, and the production of a pair of sole-upper integrated shoes can be carried out by being arranged in a heating container.
