Technical Field

[0001] The invention relates to the technical field of shoe moulds, in particular to a shoe sole mould with an adjustable cavity. Background Art

[0002] In today's market, consumers have an increasing demand for personalized products. However, sole molds that cannot adjust the size and shape of the cavity are difficult to meet such personalized needs because they can only produce soles of fixed sizes and styles. This makes companies more passive in the face of market changes and diversified consumer demand. In order to meet the production needs of soles of different sizes and styles, companies need to purchase a large number of molds of different specifications. The production costs of these molds are usually high, especially for some sole molds with complex shapes and high precision requirements. The production cost is even more expensive, which undoubtedly increases the production cost investment of the company.

[0003] Therefore, we designed a sole mold with adjustable cavity to solve the above problems. Summary of the invention

[0014] 1. The controller controls the operation of the electric telescopic shaft and the adjustment ball, and the mold can automatically complete the adjustment process of the cavity without manual intervention, which improves production efficiency. The adjustment ball rotates in the ball socket at the bottom of the flexible board, so that each small part of the flexible board can adjust the angle to achieve the effect of fully fitting the surface of the shoe sample, adapting to the production needs of various shoe samples, without the need to prepare a special mold for each specific shoe sample, reducing costs and greatly improving production flexibility.

DETAILED DESCRIPTION

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

A ball socket 9 is provided at the bottom of the flexible board 10, and the ball socket 9 is rotatably connected to the adjustment ball 8. An annular groove is provided on the outer surface of the ball socket 9, and an electromagnetic coil A17 and an electromagnetic coil B18 are placed in the annular groove. A storage module 16 is provided in the controller 3, and the storage module 16 is used to store the adjustment parameters of the electric telescopic shaft 7 corresponding to different sole models, as well as the current intensity and direction parameters of the electromagnetic coil A17 and the electromagnetic coil B18 for different sole models. The controller 3 and the electric telescopic shaft 7 are electrically connected through a cable, and the electromagnetic coil A17 and the electromagnetic coil B18 are connected to the controller 3 through a wire.

[0025] In specific implementation, since the storage module 16 inside the controller 3 pre-stores the adjustment parameters of the electric telescopic shaft 7 corresponding to various types of soles, the signal will be transmitted to the controller 3, and the controller 3 controls the power supply to turn on, so that the electric telescopic shaft 7 moves in the vertical direction. Similarly, the controller 3 also controls the current intensity and direction of the electromagnetic coil A17 and the electromagnetic coil B18, and then controls the rotation direction and angle of the adjustment ball 8. When producing different types of soles, it can be quickly called without tedious parameter adjustment every time, thereby improving production efficiency.

[0026] See also Figure 4 As shown, the flexible board 10 is made of polyimide, which is wear-resistant, high-temperature-resistant, and can withstand large tensile forces without being easily broken.

[0027] See also Figure 1-5 A friction block 11 is fixedly connected to the inner arc surface of the ball socket 9, and the friction block 11 contacts the adjusting ball 8, thereby increasing the resistance to rotation and preventing unnecessary movement during the manufacturing process.

[0028] See also Figure 1 A restore button 12 is provided on the controller 3, and a signal output end of the restore button 12 is electrically connected to a signal input end of the controller 3. By operating the restore button 12 on the controller 3, a signal is sent to the controller 3 to move the electric telescopic shaft 7 to its original position.

[0029] See also Figure 1-2 A handle 4 is provided on both the lower die 1 and the upper die 2 to facilitate the operator to open and close the upper die 2 and the lower die 1.

[0030] See also Figure 1-5 The outer tube of the electric telescopic shaft 7 is made of high-strength aluminum alloy, has good corrosion resistance and wear resistance, and can maintain stable performance during long-term use.

[0031] See also Figure 5 The friction block 11 is made of rubber and has a high friction coefficient, which can effectively increase the friction between the adjustment ball 8 and the ball socket 9 and improve the stability of the sole mold during use.

[0032] See also Figure 1-2 A positioning block 14 and a positioning groove 15 are respectively provided at the edges of the opposite sides of the upper mold 2 and the lower mold 1. The positioning block 14 is adapted to the positioning groove 15 so that the lower mold 1 and the upper mold 2 can be accurately aligned when the molds are closed.

[0033] Working principle: When a specific model of sole needs to be produced, the power is turned on, and the corresponding sole model instruction is selected through the controller 3. The controller 3 calls the corresponding electric telescopic shaft 7 adjustment parameters from the storage module 16 according to the instruction. Under the instruction of the controller 3, the electric telescopic shaft 7 starts to move to adjust the height of each small piece of the flexible plate 10. At the same time, the electromagnetic coil A17 and the electromagnetic coil B18 generate a vertical magnetic field after power is turned on. The controller 3 generates magnetic fields of different directions and intensities by adjusting the current direction and size in the electromagnetic coil A17 and the electromagnetic coil B18, thereby driving the adjustment ball 8 to rotate to the target angle. The rotation of the adjustment ball 8 drives the corresponding part of the flexible plate 10 to change the angle. In this way, the concave shape between the upper and lower flexible plates 10 is gradually adjusted to match the target sole shape. At this time, the controller 3 controls the electric telescopic shaft 7 and the adjustment ball 8 to stop running, and the cavity adjustment of the sole mold is completed. Then, the solution can be poured in for curing and molding. After the curing and molding of the sole is completed, the upper mold 2 and the lower mold 1 are opened to take out the prepared sole. If it is necessary to switch to producing other models of soles, the controller 3 selects the corresponding model instruction again and repeats the above process.

[0034] If it is necessary to make the next production, the restore button 12 on the controller 3 can be operated to send a signal to the controller 3 to move the electric telescopic shaft 7 to the original position to prepare for the next production.
