Abstract
This utility model discloses an in-mold automatic gate cutting mold, comprising: a fixed mold insert, a moving mold insert, a moving mold gate insert, a slide rail, a slider, an inclined guide post, and a cutter. The fixed mold insert and the moving mold insert interlock to form a product cavity. The moving mold gate insert is disposed within the moving mold insert and extends out of the moving mold insert. The fixed mold insert and the moving mold gate insert interlock to form a gate channel, which communicates with the product cavity. The slide rail is disposed on the moving mold insert and located on one side of the moving mold gate insert. The slider is slidably disposed on the slide rail. The cutter is connected to the slider and faces the gate channel. The upper end of the inclined guide post is connected to the fixed mold insert, and the lower end of the inclined guide post passes through the slider and extends into the moving mold insert. Through the application of this utility model, an in-mold automatic gate cutting mold is proposed, which can automatically cut the gate without manual operation, thus improving production efficiency and shortening the production cycle by overcoming the inefficiency of traditional manual gate cutting.
