Abstract

A disclosed outer charging type material-storage cylinder die head comprises a material-storage cylinder barrel, and an outer core rod, a material press ring and an adjusting shaft all arranged in the material-storage cylinder barrel; one end of the material-storage cylinder barrel is provided with an end cover, and the other end is connected with a die material inlet; the adjusting shaft is arranged at a middle shaft inside the material-storage cylinder barrel; the outer core rod is arranged between the material press ring and the material-storage cylinder barrel; a material inlet hole of the material-storage cylinder barrel is connected with the outer core rod, and a flow channel on the outer core rod is communicated with the interior of the material-storage cylinder barrel; and gaps are reserved between the material press ring and the outer core rod, and between the material press ring and the adjusting shaft.

Description

technical field [0001] The invention belongs to the field of plastic processing, in particular to a storage cylinder die head for extruding plastic. Background technique [0002] Extrusion, also known as extrusion, is a plastic molding process and one of the important methods for thermoplastic molding. Extrusion molding is to heat the plastic raw material to make it into a viscous flow state. Under the action of pressure, it passes through the extrusion mold to form a continuous body with a cross-section similar to the shape of the die, and then cools and shapes it into a glass state, which is obtained by cutting. Plastic products with certain geometric shapes and dimensions. [0003] In the above process, the molten plastic is sent to the die head of the storage tank by the screw rod, and then extruded by the die head of the storage tank into the mold connected to the nozzle of the die head of the storage tank to be formed. However, the material extruded from the conventi...
