Technical Field
[0001] The present application relates to the technical field of shoe production, and particularly relates to a pressing device for shoe production. Background Art
[0002] Currently, when processing shoe materials, it is necessary to apply glue and press one side of the insole and one side of the outsole of the shoe to make them adhere tightly without gaps.
[0003] However, in order to improve the pressing efficiency, the existing pressing machine only presses the shoes for a few seconds. This causes the shapes of the insole and the outsole that do not fully match to return to their respective shapes due to the release of pressure. Since the glue cannot bond large gaps, it will cause the shoes to come unglued along the gaps during later use, resulting in quality problems. In view of the above related technologies, the applicant proposes a pressing device for shoe production with a pressure-holding effect. Utility Model Content

A pressure-holding structure is arranged between the upper mold and the lower mold. The pressure-holding structure includes a threaded cover sleeved and vertically connected to the outside of the upper mold. The threaded cover can be screwed to the outer side wall of the lower mold. A balance structure that elastically abuts against the lower part of the threaded cover is vertically arranged at intervals around the side wall of the upper mold. One side of the press is provided with a pressure-applying structure.

[0027] Refer to Figure 1 , 3 , a balancing structure 7 is provided on the circumferential side wall of the upper mold 4 at intervals in a lifting manner and elastically abuts against the lower side of the threaded cover 61. The balancing structure 7 includes a support block 71 and a support spring piece 72. The support block 71 is connected to the side wall of the lower mold 5 in a lifting manner and can abut against the bottom wall of the upper mold 4; one end of the support spring piece 72 is fixed to the lower mold 5, and the other end is fixed and drives the support block 71 to rise corresponding to the top end of the thread on the outer side wall of the lower mold 5. The support block 71 keeps the threaded cover 61 horizontal during the docking process and prevents the threaded cover 61 from tilting and causing thread slipping.
[0028] Refer to Figure 1 , 2 , a pressing structure 8 is provided on one side of the press 3. The pressing structure 8 includes a lower pressing fork 81, a pressing annular groove 82, a driving motor 83 and a lifting barrel spring 84. The lifting barrel spring 84 slides horizontally towards the threaded cover 61 and is connected to the working platform 1; the driving motor 83 is fixed to the movable end of the lifting barrel spring 84, and the output shaft of the driving motor 83 is meshed and connected to the side wall of the threaded cover 61; the pressing annular groove 82 is opened on the outer side wall of the threaded cover 61; the lower pressing fork 81 is fixed to the driving motor 83 and extends towards the threaded cover 61, and an upward inclined slope is provided on the bottom surface of the end of the lower pressing fork 81 close to the threaded cover 61.
