Description

Technical Field

[0001] The utility model relates to the technical field of molded products, in particular to highly flame-retardant molded products. Background Art

[0002] Molding is the abbreviation of compression molding, also known as compression molding. It is a plastic processing method in which plastic or rubber compounds are formed into products by heating and pressurizing in a closed mold cavity. Presses and molds are usually used in the production of molded products. The function of the press is to apply pressure to the plastic through the mold to complete the production of molded products.

[0003] After searching, a DMC molded product seamless ejection mold with publication number CN220146508U was found. This utility model relates to a DMC molded product seamless ejection mold, which belongs to the field of molded products, and includes two side plates, a top plate, a molding control board, a movable mold and a static mold. The top plate is fixedly installed on the top of the two side plates, the molding control board is slidably connected between the two side plates, two cylinders are fixedly installed on the top of the top plate, and the output shafts of the two cylinders are fixedly connected to the top of the molding control board, the static mold is fixedly installed between the two side plates, a molding groove is provided on the static mold, and a movable mold is fixedly installed on the bottom of the movable mold.
