Description

Technical Field

[0001] The utility model relates to the technical field of mold locking, in particular to a locking device for a PU anti-fatigue mat forming mold. Background Art

[0002] PU anti-fatigue mats are widely used in industrial, commercial, and domestic environments due to their excellent fatigue resistance and comfort. These mats are produced using a specific molding mold, and the mold's locking mechanism is a critical component in ensuring the quality of the mat's molding. The locking mechanism must provide sufficient force to maintain mold stability during the foaming process.

[0003] After the mat is finished, the upper and lower molds are usually separated and cleaned with an air gun. However, residual PU material, debris, and dust may inevitably adhere to the locking mechanism's slots, making them difficult to clean. Over time, the accumulation of these residues can cause the slots to become clogged, affecting the proper functioning of the locking mechanism and reducing its effectiveness. Regular cleaning is usually required, especially of small areas like the slots, making maintenance more difficult. Utility Model Content

[0026] A partition 134 is fixedly connected to the outer wall of one side of the rotating seat 131, and the extrusion unit 140 includes a hydraulic rod 141. The outer wall of the hydraulic rod 141 is fixedly connected to the inner wall of the square plate 113, and the outer wall of one end of the hydraulic rod 141 is fixedly connected to a cross 142. The outer wall of one end of the cross 142 is fixedly connected to a frame 144. A spring telescopic rod is fixedly connected between the bottom wall of the cross 142 and the outer wall of the upper mold base 112. An air cavity 143 is opened inside the frame 144, and a plurality of circular holes 126 are opened at equal intervals on the outer wall of the trapezoidal block 124.
