Abstract

A size-fine-tuning railway gauge block mold is characterized by comprising a movable mold core and a plurality of inserts, wherein the inserts are detachably mounted in the mold cavity of the movablemold core, the sizes of corresponding products are different, so the specifications of the inserts are different, and the inserts can be mounted in a fit manner with the mold cavity. According to thesize-fine-tuning railway gauge block mold, the inserts with different specifications can be changed according to the fine tuning requirements of the product sizes, the sizes of the railway gauge blocks can be adjusted rapidly and effectively, and the insert lines formed on the products are on the non-working surfaces of the products, so that the product performance is not affected. The problem that the mold requires to be modified repeatedly due to unqualified sizes is solved, the service life of the mold is prolonged, the mold modification fee and the mold modification time are saved, the mold use efficiency is improved, the cost investment in the mold use process is reduced, the product size fine tuning convenience is improved, and the mold use efficiency is improved. The invention further provides a size fine tuning method of the size-fine-tuning railway gauge block mold.

Description

technical field

[0001] The invention relates to a railway gauge block mold whose size can be fine-tuned and a size fine-tuning method thereof, which realizes the fine-tuning of the product size of the railway gauge block and belongs to the field of railway gauge block production. Background technique

[0002] Railway gauge blocks are widely used in railway fastener systems and are injection molded from nylon. The railway gauge block is the connecting part between the rail and the sleeper, and is generally placed between the shoulder of the iron seat and the rail. The railway gauge block usually has a "7"-shaped thick-walled structure. Due to the fluctuation of raw material batches, machine tools, and injection molding process parameters, etc., during the production process, there are often cases where the size is out of tolerance, and the mold needs to be loaded and unloaded repeatedly. Returning to the factory to modify the mold to adjust the size consumes a lot of time an...
