Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection molded shoe technology, specifically to a grinding and edge-removing device for injection molded shoe production. Background Technology
[0002] Injection-molded shoes typically use plastic soles. Plastic injection molding is a production method that involves directly injecting plastic material from a barrel into a mold for vulcanization, followed by bonding of fabric or leather uppers. Injection molding, performed under specific temperature and pressure conditions, imparts a degree of flexibility and elasticity to the upper and sole, fusing the two together; hence the name "injection-molded shoe."
[0003] Utility model patent application with publication number "CN217097051U" discloses a grinding and edge-removing device for injection-molded shoe production. The device mainly includes a support frame, power supply, wires, a grinding machine, a two-way rotating rod with wheels, a slider, a collar, a mold rod, a shoe sole mold, and a clamping sleeve. During use, rotating the clamping sleeve causes the shoe sole mold to rotate via the mold rod, which in turn rotates the shoe sole. This allows the operator to perform circular grinding of the shoe sole while standing in a specific position, ensuring high grinding efficiency.
[0004] The aforementioned document discloses a grinding and edge-removing device for injection-molded shoes, which has the following defects: when grinding injection-molded shoes, personnel need to stand next to the device at all times, and the debris generated during grinding can easily enter the personnel's internal organs and cause adverse effects.
[0005] Therefore, it can be seen that the existing grinding and edge-removing devices used in injection molded shoe production do not have a structure that prevents debris from directly contacting personnel. Utility Model Content

The housing 101 has two third slide rails 10101 installed inside it. The movable wheels 4012 are slidably connected to the inside of the third slide rails 10101. The outer surface of the housing 101 has a groove, and the U-shaped part 401 is equipped with a push rod 4013 through the groove.
[0037] By setting up a U-shaped part 401, a first push block 402, a first spring 403, a first mounting base 404, a grinding wheel 405, a moving plate 406, a hydraulic rod 407, a second push block 408, a second spring 409, a second mounting base 4010, a rotary motor 4011, a moving wheel 4012, a third slide rail 10101, and a push rod 4013, the grinding structure 4 moves past the injection molded shoe, and the thrust generated by the first spring 403 and the second spring 409 causes the grinding wheel 405 to fit against the injection molded shoe for grinding.
[0038] In use, first open the dust door 102, then open the hydraulic rod 407 to move the moving plate 406 and the upper slide rail 201 upwards. Next, place the injection-molded shoe 3 to be ground onto the receiving plate 203. Then, control the hydraulic rod 407 to drive the pressing plate 202 downwards and press the injection-molded shoe. After closing the dust door 102, move the push rod 4013 to move the grinding structure 4 closer to the injection-molded shoe. When the grinding structure 4 contacts the injection-molded shoe, the grinding wheel 405 is first pushed by the injection-molded shoe, causing the grinding wheel 405 to carry the first push block 402 and the second push block 405. Push block 408 moves away from the injection molded shoe. During the movement, the first push block 402 and the second push block 408 are pushed by the first spring 403 and the second spring 409, which drives the grinding wheel 405 to move back to its original position so that the grinding wheel 405 fits against the injection molded shoe for grinding. When the grinding structure 4 moves away from the injection molded shoe, the grinding is successful. During the grinding process, debris often flies out. The dust door 102 should be closed first, and then the blower 103 should be turned on to blow the debris into the collection box 105. Then the debris in the collection box 105 can be poured out.
