Technical Field
[0001] The present application relates to the technical field of shoe manufacturing, and in particular to a bottom mold locking mechanism. Background Art
[0002] Soles, especially midsoles, are typically made from polymers such as ethylene vinyl acetate (EVA). The standard manufacturing process for such polymers includes injection molding the sole material into a conventional sole mold.
[0003] In the process of sole production, the sole mold needs to be fixed first, and then injection molding is performed. In the prior art, the bottom of the sole mold is mostly fixedly connected with a pin, and the pin is fixed on the frame, thereby completing the fixing of the sole mold.
[0004] In view of the above-mentioned related technologies, in order to prepare soles of different sizes, it is usually necessary to replace the sole molds of corresponding sizes. However, most of the existing sole molds are directly fixed on the frame. When the sole mold needs to be replaced, it is inconvenient to replace the sole mold, which is easy to cause irreversible damage such as cracking to the sole mold, so there is room for improvement.

Then operate the translation member to control the translation plate to move horizontally on the lifting seat, so that the nail body of the pin passes through the second hole. At this time, the nail cap of the pin cannot pass through the second hole, and the positioning of the pin is completed. Then operate the lifting member to control the lifting plate to move vertically downward, so that the translation plate presses down the pin, and a downward force will be generated on the sole mold, thereby pressing the sole mold on the frame.

[0036] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, those skilled in the art may combine and combine different embodiments or examples and features of different embodiments or examples shown in the present application.
[0037] The present application embodiment discloses a bottom mold locking mechanism. Figure 1The locking mechanism includes a support base 1, a lifting member 2, a lifting base 3, a translation plate 4 and a translation member 5. The support base 1 is used as a supporting carrier, and the lifting base 3 is arranged on the support base 1 for movement in the vertical direction. The lifting member 2 is installed on the support base 1 and connected to the lifting base 3. The lifting member 2 is used to control the lifting base 3 to move up and down. In this embodiment, the lifting member 2 is a linear cylinder, and the piston rod of the linear cylinder is connected to the lifting base 3. When the piston rod of the linear cylinder is extended and retracted, the lifting base 3 can be moved up and down.
[0038] A slide groove 6 is provided on the lifting seat 3, and the translation plate 4 is slidably connected in the slide groove 6; the translation member 5 is installed on the lifting seat 3 and connected to the translation plate 4, and the translation member 5 is used to control the horizontal movement of the translation plate 4. In this embodiment, the translation member 5 is a stretching cylinder, and the piston rod of the stretching cylinder is connected to the translation plate 4. The stretching cylinder can realize the linear movement of the translation plate 4, thereby controlling the movement of the translation plate 4. Among them, a limiting hole 7 is provided on the translation member 5, and the limiting hole 7 includes a first hole 71 and a second hole 72 that are interconnected. The cross section of the first hole 71 is circular, and the cross section of the second hole 72 is rectangular. The width of the first hole 71 is greater than the width of the second hole 72. The first hole 71 is used for the nail cap of the pin to pass through, and the second hole 72 is used for the nail body of the pin to pass through and to limit the nail cap of the pin.
[0039] When the sole mold needs to be fixed, the sole mold is first placed on the lifting seat 3, and the pin at the bottom of the sole mold is passed through the first hole 71. Then the translation member 5 is operated to control the translation plate 4 to move horizontally on the lifting seat 3, so that the nail body of the pin passes through the second hole 72, changing the relative position of the pin and the limiting hole 7. At this time, the nail cap of the pin cannot pass through the second hole 72, and the positioning of the pin is completed.
[0040] Then, the lifting member 2 is operated to control the lifting plate to move vertically downward, so that the translation plate 4 presses down the pin, which will generate a downward force on the sole mold, thereby pressing the sole mold on the frame. When the sole mold needs to be replaced, the pressure of the lifting member 2 on the sole mold can be removed, and then the pin of the sole mold is passed through the limiting hole 7, and the sole mold is replaced with a new sole mold and then pressed.
[0041] In some embodiments, an anti-skid layer (not shown in the figure) is provided on the inner wall of the limiting hole 7. The anti-skid layer is made of a polymer material, which may be, but is not limited to, rubber or polyvinyl chloride. When the pin is inserted into the limiting hole 7, the body of the pin will contact the inner wall of the limiting hole 7. Due to the presence of the anti-skid layer, the static friction between the pin and the translation plate 4 can be increased, thereby improving the connection stability between the pin and the translation plate 4.
[0042] Specifically, the piston rod of the linear cylinder is connected to the lifting seat 3 through a connecting rod 8, the cross-sectional area of the connecting rod 8 is larger than the area of the piston rod of the linear cylinder, and the two ends of the connecting rod 8 are respectively connected to the piston rod of the linear cylinder and the lifting seat 3. The connecting rod 8 replaces the piston rod of the linear cylinder to be connected to the lifting seat 3, which can increase the force-bearing area of the lifting seat 3 and improve the stability of the lifting seat 3 when moving.
[0043] In addition, a protective shell 9 is installed on the support seat 1. The protective shell 9 is detachably connected to the support seat 1. The protective shell 9 is locked to the support seat 1 by a fastener 10. The fastener 10 is a detachable object such as a fastening bolt or a fastening screw. The connecting rod 8 is lifted and arranged inside the protective shell 9. The protective shell 9 is used to protect the connecting rod 8 to prevent the connecting rod 8 from being directly exposed. In some embodiments, a key block 11 is also fixedly connected to the outer surface of the connecting rod 8. The key block 11 is arranged along the moving direction of the connecting rod 8. A key slot 12 is provided on the inner wall of the protective shell 9. The key block 11 slides in the key slot 12. When the linear cylinder drives the connecting rod 8 to move up and down, the key block 11 can move along the key slot 12, thereby achieving a guiding and limiting role for the connecting rod 8, limiting the circumferential movement of the connecting rod 8, and improving the stability of the movement of the lifting seat 3.
[0044] The implementation principle of a bottom mold locking mechanism in the embodiment of the present application is as follows: when the sole mold needs to be fixed, the sole mold is first placed on the lifting seat 3, and the pin at the bottom of the sole mold is passed through the first hole 71. Then, the translation member 5 is operated to control the translation plate 4 to move horizontally on the lifting seat 3, so that the pin body passes through the second hole 72, and the relative position of the pin and the limiting hole 7 is changed. At this time, the pin cap cannot pass through the second hole 72, and the positioning of the pin is completed.
[0045] Then, the lifting member 2 is operated to control the lifting plate to move vertically downward, so that the translation plate 4 presses down the pin, and at this time, a downward force is generated on the sole mold, thereby pressing the sole mold onto the frame.
[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
