[0044] The working principle of the utility model is as follows:
[0045] When in use, the production material is first injected into the molding cavity 2 of the lower mold 1, and then the electric push rod 12 is started to control the upper mold 13 to move down to close the mold, and the material is extruded and molded. After the foam sole is formed, the upper mold 13 is raised and opened by the electric push rod 12, and then the staff manually squeezes and pushes the square rod 92 toward the inside of the lower mold 1. Figure 5 The first inverted truncated cone-shaped pressing block 93 shown in the figure can squeeze the driving wheel 7, and can control the lifting seat 4 to drive the two ejection mechanisms 8 to move upward synchronously. By raising the lifting seat 4, the molded foam sole in the molding cavity 2 can be ejected and demolded for the first time, and by Figure 3 The grooves 5 provided in the middle of the left and right ends of the lifting seat 4 and the limit blocks 3 fixedly provided on the inner wall of the molding cavity 2 can limit the lifting range of the lifting seat 4 and improve the lifting stability of the lifting seat 4;
[0046] After the lifting seat 4 is lifted up for the first ejection and demoulding, the square rod 92 is manually controlled to rotate 180° in the clockwise direction. During this process, the first pressing block 93 can always resist the transmission wheel 7 to ensure that the position state of the lifting seat 4 remains unchanged, and the second pressing block 94 eccentrically fixed to the outside of the square rod 92 can squeeze the steel ball 83 when rotating, and squeeze the ejector pin 81 to rise upward from the inside of the lifting seat 4, so that the foam sole adhered to the upper part of the lifting seat 4 can be ejected and demoulded for the second time. By using two ejections, the finished foam sole can be efficiently and quickly demoulded, and the material can be taken more quickly and conveniently;
[0047] Since the square rod 92 can drive the rotating sleeve 95 which is slidably connected with it to rotate synchronously so that the clockwork spring 96 can store force, after demoulding is completed, when the square rod 92 is released, the clockwork spring 96 and the third spring 97 are used to facilitate the rotation and reset of the square rod 92, the first pressure block 93, the second pressure block 94 and the rotating sleeve 95, and the protruding structure of the outer wall of the front end of the rotating sleeve 95 can be used to limit the rotation range of the rotating sleeve 95 and the square rod 92 with the cooperation of the stop block 10, and the setting of the first spring 6 and the second spring 82 can facilitate the downward movement and reset of the lifting seat 4 and the ejector pin 81, so as to facilitate the subsequent use of the molding equipment.
[0048] The above are only preferred specific embodiments of the utility model and are not intended to limit the protection scope of the utility model; any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the protection scope determined by the claims.
