[0037] The present application embodiment discloses a lifting mechanism. Figure 1 , the lifting mechanism includes a support seat 1, a lifting frame 2 and a first driving member 3. The support seat 1 serves as a carrier, and the lifting frame 2 is lifted and arranged on the support seat 1. The lifting frame 2 moves up and down in the vertical direction, and the injection machine is installed on the lifting frame 2. The first driving member 3 is installed on the support seat 1 and connected to the lifting frame 2. The first driving member 3 is used to control the lifting frame 2 to move up and down. The first driving member 3 is a cylinder, an oil cylinder or an electric push rod. In this embodiment, it is a cylinder, and the piston rod of the cylinder is fixedly connected to the lifting frame 2. As shown in the figure, there are several first driving members 3 in this embodiment. The first driving members 3 are distributed at intervals on the support seat 1 and are all connected to the lifting frame 2. Multiple first driving members 3 jointly drive the lifting frame 2 to move up and down, and the stability of the lifting frame 2 during movement is improved by multi-point control. Among them, a control box 4 is provided on one side of the support seat 1, and the control box 4 is used to control the operation of the first driving member 3.

[0038] The injection machine is installed on the lifting frame 2, and the first driving member 3 is used to control the lifting of the injection machine. When the staff needs to spray liquid PU according to the flow channel, the injection machine can be controlled to lift to the corresponding flow channel for injection. There is no need to arrange multiple injection machines, which makes it convenient to inject the soles and reduce production costs.

[0039] Combination Figure 2 In some embodiments, a slide rail 5 and a slide seat 6 are connected to the lifting frame 2, and two slide rails 5 are arranged in parallel. The slide seat 6 is slidably connected to the slide rail 5, and the slide seat 6 is used for installation of the injection machine. When the slide seat 6 moves on the slide rail 5, the horizontal position of the injection machine will also change accordingly, so that the horizontal and vertical positions of the injection machine can be adjusted, making the position of the injection machine more flexible and improving practicality. Specifically, a second driving member 7 is fixedly installed on the lifting frame 2, and the second driving member 7 is connected to the slide seat 6 and is used to control the movement of the slide seat 6.

[0040] The second driving member 7 is detachably connected to the slide 6. In this embodiment, the second driving member 7 is a linear cylinder, and the piston rod of the linear cylinder is connected to the slide 6 through a connecting assembly 8. The connecting assembly 8 includes a rotary motor 81 and a clamping block 82. The rotary motor 81 is fixedly connected to the piston rod of the linear cylinder, and the clamping block 82 is fixedly connected to the output shaft of the rotary motor 81. A clamping groove 9 is provided on one side of the slide 6 facing the clamping block 82. The notch of the clamping groove 9 has the same shape as that of the clamping block 82, and the clamping block 82 is clamped on the slide 6.

[0041] During installation, the linear cylinder is first operated to gradually bring the block 82 closer to the slide 6, so that the block 82 is inserted into the slot 9, and then the rotary motor 81 is operated to control the block 82 to rotate, so that the block 82 and the slide 6 rotate relative to each other, so that the notches of the block 82 and the slot 9 are mutually misaligned, thus realizing the connection between the slide 6 and the linear cylinder. When the linear cylinder is extended and retracted, the slide 6 can be driven to move linearly.

[0042] In addition, an interception plate 10 is detachably mounted on one end of the slide rail 5. The interception plate 10 is locked on the lifting frame 2 by a fastener, and the interception plate 10 is used to intercept the slide 6. In this embodiment, the fastener is a detachable object such as a fastening bolt or a fastening screw. When the slide 6 slides on the slide rail 5, the interception plate 10 can play a role of blocking and limiting, preventing the slide 6 from falling directly from the end of the slide rail 5. At the same time, since the fastener is a detachable object, when the injection molding machine needs to be repaired, the interception plate 10 can be removed first, and then the slide 6 can be removed from the slide rail 5 without causing interference.

[0043] The implementation principle of a lifting mechanism in an embodiment of the present application is: when the staff needs to spray liquid PU according to the flow channel, the first driving member 3 can be used to control the injection machine to rise and fall to the corresponding flow channel for injection, without the need to arrange multiple injection machines, thereby facilitating the injection molding of the sole.
