Problems solved by technology

Due to the influence of temperature changes, screw gap size and other factors, the traditional plastic extruders have different extrusion volumes under continuous working conditions.
Therefore, the finished product after molding will be different due to the change of extrusion volume.

Abstract

The invention relates to an extruder. The extruder comprises a hopper and an extruding mold; the hopper is internally provided with extruding screws; the extruding mold is arranged at one end of the hopper, and is connected with the hopper through a discharge pipeline, wherein the extruding mold comprises an outer mold, a mold core and a mold panel; the outer mold is provided with a conical groove; the mold core is arranged in the conical groove; the mold panel is fixed outside the outer mold and the mold core so as to enable the outer mold and the mold core to be integrated; a plurality of channels are distributed on the outer surface of the mold core for enabling extruded substances to pass through; the mold panel also has mold holes corresponding to the channels. The extruder provided by the invention is simple in structure, can extrude multiple strands of extruded substances synchronously, is stable in performance, and is adjustable in speed.

Description

technical field [0001] The invention relates to the technical field of extrusion molding devices, in particular to an extruder. Background technique [0002] The conventional extruder is composed of motor, motor pulley, V-belt, reducer pulley, reducer, hopper, electrical control box and other parts. The plastic extruder is a machine that heats the plastic raw material and then is extruded into a mold by screw rotation. The rotation of the screw in the barrel produces extrusion thrust, which can change the plastic raw material from solid to molten liquid. The plastic raw material is compressed and mixed in the screw, and finally molded into a qualified part or appliance. Due to the influence of factors such as temperature changes and screw gap size, the extrusion volume of traditional plastic extruders is not equivalent under continuous working conditions. Therefore, the finished product after molding will be different due to the change of extrusion volume. With the progre...
