Description

Technical Field

[0001] This utility model relates to a mold ejection structure for processing magnetic snap fasteners, and belongs to the field of magnetic snap fastener technology. Background Technology

[0002] Magnetic snaps are mainly formed by stamping using stamping dies during the production and processing process. After stamping, the magnetic snaps are usually removed by a stripping structure.

[0003] According to the announcement number "CN221952179U", a mold stripping structure includes a stripper plate, a sleeve fixedly installed above the stripper plate, and a push rod movably inserted into the inner side of the sleeve. A first spring is also fixedly installed between the push rod and the sleeve. By directly fixing the sleeve to the stripper plate, the push rod is inserted into the sleeve, eliminating the need to modify the upper mold and ensuring the uniformity and applicability of the upper mold.

[0004] The above-mentioned stripping structure mainly uses the method of directly fixing the sleeve on the stripper plate, with the ejector pin inserted into the sleeve. This eliminates the need to modify the upper mold, ensuring the uniformity and applicability of the upper mold. However, during use, we found that the stripper plate of the above mold is a fixed design, and it still needs to be stripped by ejector pins, which affects the processing efficiency of the magnetic snap fastener.

[0009] In the above-mentioned mold stripping structure for magnetic snap-on processing, a punch hole is provided at the center of the stripping plate, and the stripping plate is fixedly connected to the electric push rod of the stamping mold through a connecting rod.

[0010] In the above-mentioned mold stripping structure for magnetic snap-fit ​​processing, the limiting guide post consists of a fixed base, an auxiliary guide sleeve, a spring, a guide post body, and an inner sleeve. The fixed base is fixedly connected to the assembly hole. The fixed base is fixedly connected to the bottom end of the guide post body by a hexagonal countersunk screw. The guide post body is fixedly provided with an auxiliary guide sleeve. A spring is nested in the middle of the guide post body. The inner sleeve is fixedly connected to the corner of the bottom end of the upper template. The top of the guide post body is nested in the inner sleeve.
