Processing technology for preparing rubber magnetic strip from magnetic powder

Abstract

The invention relates to a processing technology for preparing a rubber magnetic stripe from magnetic powder. The processing technology involves a bottom plate, a fixed mold frame and a material injection device, wherein the fixed mold frame is arranged in the middle of the upper end of the bottom plate, the material injection device is arranged above the fixed mold frame, and the lower end of the material injection device is arranged on the bottom plate. According to the processing technology, the problems that when existing equipment carries out material injection processing on a molten mixture, the material injection effect is poor, material injection is inaccurate, generally, the molten mixture is manually loaded into a mold and then pressed, one-step forming cannot be achieved, the production and processing efficiency of the rubber magnetic strips is affected, and when the existing equipment carries out material injection processing on the rubber magnetic strips, formed rubber magnetic strips cannot be effectively ejected out, so that manual collection is inconvenient, and subsequent processing of the rubber magnetic strips is not facilitated are solved.

Description

technical field [0001] The invention relates to the field of processing rubber magnetic strips, in particular to a processing technology for preparing rubber magnetic strips from magnetic powder. Background technique [0002] Rubber magnetic strip is a kind of magnetic strip. It is mainly used in door seal rubber sleeves of refrigerators, kitchen appliances, bathroom facilities, doors and windows, etc. Because of its moderate suction, it has good sealing performance and adapts to temperature after being combined with plastic sleeves to form a door seal. Wide range, easy to open and durable, so it is widely used in various industries. [0003] At present, the existing rubber magnetic strips usually have the following defects during production and processing: 1. When the existing equipment injects the molten mixture, the injection effect is poor and the injection is inaccurate. Putting the melted mixture into the mold and then compacting it can not be formed in one step, whic...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem of poor injection effect and inaccurate injection of the existing equipment when the molten mixture is injected. Usually, the molten mixture is manually put into the mold and then compacted, which cannot be done in one step. Molding affects the production and processing efficiency of rubber magnetic strips, and the existing equipment cannot effectively eject the formed rubber magnetic strips when the rubber magnetic strips are injected, resulting in inconvenient manual collection, which is not conducive to Subsequent processing of rubber magnetic strips and other problems
