Description

Technical Field

[0001] The utility model relates to a shoe-making moulding machine with uppers, belonging to the technical field of shoe-making equipment with uppers. Background Art

[0002] The existing upper shoe-making molding machine is shown in the Chinese utility model patent "Authorization Announcement No.: CN201296056Y; Authorization Announcement Date: August 26, 2009; Name: Rubber Foaming Molding Machine for Shoes". It consists of a bracket and a clamping device arranged in the middle of the bracket (the clamping device includes a sole core mold clamping mechanism and a sole side mold clamping mechanism). The upper beam on the top of the bracket is rotatable, and two shoe lasts are arranged on the rotatable upper beam. When in use, the upper beam can be manually rotated to achieve the correspondence between the two shoe lasts and the clamping devices below them. This scheme has the following defects: 1. The shoe last is fixed right above the mold clamping device, and the operator can only stand on the outside of the bracket. The worker is far away from the shoe last, which makes operation inconvenient; 2. Due to inevitable design and manufacturing errors and other reasons, there are gaps between the components of the shoe last flipping structure. During the molding force process, the shoe last flipping structure is under pressure, which easily causes the instep of the shoe last to bend up, resulting in defective shoes; 3. The shoe last is not only rotatable, but also needs to be pressed and lifted when the shoe last is clamped and demolded with the sole mold. (i.e. moving the shoe last down and moving the shoe last up), and the movable connection of moving the shoe last up and down will further increase the chance of the shoe last curling up during the molding force process, which will further increase the defective rate of shoes; 4. The maximum molding pressure of traditional rubber molding machines is only about 10 tons, which may easily lead to unclear sole patterns and air pockets in the corners of the soles ("air pockets" are caused by the rubber itself generating gas, and the 10-ton mold pressure is not enough to exhaust the gas, resulting in air pockets). There is a problem of product defects caused by insufficient mold pressure. Utility Model Content

[0003] The purpose of the utility model is to address the above-mentioned technical defects of the existing upper shoe molding machine, break through the inherent thinking in the industry, and provide a large-tonnage upper shoe molding machine that does not bear pressure during the flipping of the shoe last. The molding machine is provided with a rotating part for rotating the shoe last on the front side of the bracket, which is convenient for workers to operate on the shoe last (install the upper or remove the finished shoe). At the same time, an outer slideway is provided on the rotating part to cooperate with the inner slideway on the top of the bracket. On the one hand, it solves the problem of longitudinal movement of the shoe last. On the other hand, it also solves the problem that the shoe last in the existing molding machine is connected in multiple places by movable connections (when working, the shoe last needs to be flipped and moved up and down), which causes the molding force to cause the instep of the shoe last to curl up. The utility model has outstanding practicality.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A shoe-making molding machine with uppers includes a bracket, a rotating member is rotatably mounted on the front side of the top of the bracket, two or more axial outer slides are arranged on the side of the rotating member, a shoe last is arranged on the outer slides, and an inner slide is arranged on the lower side of the top of the bracket, which is longitudinally aligned with the outer slide on the lower side of the rotating member. When the outer slide is rotated to the lower side of the rotating member and longitudinally aligned with the inner slide, the shoe last can slide back and forth between the outer slide and the inner slide by longitudinal pushing. When the shoe last is pushed to the set position of the inner slide, the vertical correspondence between the shoe last and the sole mold in the middle of the bracket can be achieved.

[0006] By adopting the above technical scheme, a continuous upper shoe molding machine is provided, which is provided with a rotating part for rotating the shoe last on the front side of the bracket, so that workers can operate on the shoe last (install the shoe upper or remove the finished shoe), and at the same time, an outer slideway is provided on the rotating part to cooperate with the inner slideway on the top of the bracket. On the one hand, the problem of longitudinal movement of the shoe last is solved, and on the other hand, the problem of the shoe last in the existing molding machine being connected in multiple places by movable connections (when working, the shoe last needs to be turned over and moved up and down) is solved, which causes the molding force to cause the instep of the shoe last to warp up.

[0007] The utility model is further configured as follows: the mold pressing machine of the molding machine is 20 tons or more, and the top of the bracket is also provided with an anti-upward device for preventing the instep of the shoe last from being upturned.

[0008] By adopting the above technical solution, an anti-warping device for preventing the instep of the shoe last from warping up is arranged on the top of the bracket, which can further solve the problem of the instep of the shoe last warping up.

[0009] The utility model is further configured as follows: the rotating member is rotatably arranged on the front side of the top of the bracket in the form of a rotating shaft obliquely facing forward and downward, and the shoe last on the outer slideway at the top of the rotating member is arranged obliquely facing forward and upward.

[0010] By adopting the above technical solution, the rotating part is designed to be inclined forward and downward, and the shoe last on the outer slide at the top of the rotating part is arranged obliquely forward and upward, which greatly facilitates the workers to put on the shoe uppers and disassemble the finished shoes.

[0011] The utility model is further configured as follows: the back and forth sliding of the shoe last between the outer slideway and the inner slideway is automatically realized by the longitudinal pushing device, and the rotation of the rotating member is automatically realized by the rotary driving device.

[0012] By adopting the above technical solution, a longitudinal pushing device is used to automatically push the shoe last, and a rotary driving device is used to realize the automatic rotation of the rotating part, thereby realizing automation, reducing the labor intensity of workers and improving production efficiency.

[0013] The main beneficial effects of the utility model are:

[0014] 1. The new molding machine is provided with a rotating part for rotating the shoe last on the front side of the bracket, which is convenient for workers to operate on the shoe last (install the upper or remove the finished shoe). At the same time, an outer slideway is provided on the rotating part to cooperate with the inner slideway on the top of the bracket to solve the problem of longitudinal movement of the shoe last;

[0015] 2. When the new molding machine is working, it only needs to rotate the shoe last as needed, and unlike the prior art, it does not need to press down and lift up the shoe last, which reduces a movable connection structure for the shoe last, making the fixed installation of the shoe last more reliable, and effectively reducing the probability of the shoe last instep curling up during the molding process;

[0016] 3. The new molding machine is provided with an anti-warping device on the top of the bracket to prevent the instep of the shoe last from warping up, which can further solve the problem of the instep of the shoe last warping up, and has outstanding practicality;

[0017] 4. The new molding machine designs the rotating part to be inclined forward and downward, and arranges the shoe last on the outer slideway at the top of the rotating part to be inclined forward and upward, which greatly facilitates the workers to put on the shoe upper and disassemble the finished shoes.

[0018] 5. The novel molding machine adopts a longitudinal pushing device to automatically push the shoe last, and adopts a rotary driving device to realize the automatic rotation of the rotating part, thus realizing automation, reducing the labor intensity of workers and improving production efficiency.

DETAILED DESCRIPTION

[0024] The technical solution of the utility model will be described clearly and completely below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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.

[0025] Embodiment 1:

[0026] like Figure 1 to Figure 2 As shown, a mold press for upper-jointed shoes, whose combined mold press is 20 tons or more, comprises a bracket 1, a first rotating member 81 is rotatably arranged on the front side of the top of the bracket 1, two or more first outer slides 91 are arranged on the side of the first rotating member 81, a shoe last 6 is arranged on the first outer slide 91, and a first inner slide 71 is arranged on the lower side of the top of the bracket 1, which is longitudinally aligned with the first outer slide 91 on the lower side of the first rotating member 81. When the first outer slide 91 rotates to the lower side of the first rotating member 81 and longitudinally aligns with the first inner slide 71, the shoe last 6 can slide back and forth between the first outer slide 91 and the first inner slide 71 by longitudinal pushing, and when the shoe last 6 is pushed to the set position of the first inner slide 71, the vertical correspondence between the shoe last 6 and the sole mold in the middle of the bracket 1 can be achieved. The back-and-forth sliding of the shoe last 6 between the first outer slideway 91 and the first inner slideway 71 can be achieved by manual pushing, or can be achieved automatically by a longitudinal pushing device.

[0027] The top of the bracket 1 is also provided with an anti-warping device to prevent the instep of the shoe last 6 from warping up. The anti-warping device includes a pressing cylinder 10 fixed to the top of the bracket 1 and a pressing block 12 arranged at the lower end of the telescopic rod of the pressing cylinder 10. The lower edge of the pressing block 12 is provided with an arc structure corresponding to the instep of the shoe last 6. The pressing block 12 is detachably fixed to the lower end of the telescopic rod of the pressing cylinder 10. When it is necessary to manufacture closed-toe shoes, the closed-toe shoe mold is used to replace the pressing block 12. The pressing block 12 is fixed to the telescopic rod of the top pressing cylinder 10 through the hollow bracket 11. The middle part of the hollow bracket 11 is provided with a space for the first inner slide 71 and the shoe last 6 fixing frame to pass through.

[0028] The sole mold includes a sole core mold 2 and a left / right sole mold 3. After the shoe last 6 is vertically aligned with the sole mold, the left / right sole mold 3 is first pushed horizontally, and then the sole core mold 2 is moved upward to achieve mold closing between the sole mold and the shoe last 6. The vertical pushing of the sole core mold 2 is achieved by the upward pushing cylinder 5, and the horizontal pushing of the left / right sole mold 3 is achieved by the left / right horizontal pushing cylinder 4.

[0029] Principle of use: By rotating the first rotating member 81, the shoe last 6 on the upper outer slideway of the first rotating member 81 can be directed upward, and the lower outer slideway of the first rotating member 81 can be docked with the first inner slideway 71. At this time, the worker can dismantle the finished shoe or put on the upper of the shoe last 6 on the upper side, and can push the lower shoe last 6 longitudinally to slide back and forth between the lower first outer slideway 91 and the first inner slideway 71. After moving the lower shoe last 6 to the position corresponding to the sole mold, add the sole molding material into the sole core mold 2 (directly put the rubber or plastic into the sole core mold 2). Then the left / right lateral pushing cylinder 4 controls the left / right side mold 3 of the sole to fit with the bottom of the left and right sides of the shoe last 6, and the upward pushing cylinder 5 controls the sole core mold 2 to move up to complete the mold closing with the shoe last 6 and the left / right side mold 3 of the sole. After the sole is formed, the sole core mold 2 moves down, and the left / right side mold 3 of the sole is separated to the left and right to complete the mold opening. The shoe last 6 on the first inner slide 71 is moved to the first outer slide 91 on the lower side of the first rotating part 81, and then the first rotating part 81 is turned over, and the shoe last 6 with the finished shoe is turned over to the upper side of the first rotating part 81, so that the workers can remove the finished shoes easily.

[0030] Embodiment 2:

[0031] like Figure 3 As shown, the difference between the second embodiment and the first embodiment is that the second rotating member 82 is used as the rotating member, and the second rotating member 82 is rotatably fixed to the front side of the top of the bracket 1 through a rotating drive device. The second rotating member 82 is arranged in the form of a rotating shaft obliquely facing forward and downward, and the shoe last 6 on the second outer slide 92 on the top of the second rotating member 82 is arranged obliquely forward and upward. The rotating drive device is composed of a rotating cylinder 13 and a rotating base 14. The second rotating member 82 is fixed on a turntable in the rotating base 14, and the gear on the turntable is meshed with the rack on the telescopic rod of the rotating cylinder 13. When in use, the rotating cylinder 13 drives the telescopic rod to move back and forth to drive the second rotating member 82 along Figure 3 The axis (dashed line) rotates.
