Automatic deviation adjusting extruding machine head mold and automatic deviation adjusting device

Abstract

The invention discloses an automatic deviation adjusting extruding machine head mold. The mode comprises a machine head body, an outer mold, a core mold, deviation adjusting parts, a deviation adjusting driving part and deviation adjusting auxiliary parts,wherein a cavity is formed in the machine head body, the core mold and the outer mold are contained in the cavity, the outer mold is arranged outside the core mold in a sleeve mode, and a molding cavity is formed between the outer mold and the core mold; one ends of the deviation adjusting parts penetrate through the machine head body and isconnected to the outer mold, the ends, far away from the outer mold, of the deviation adjusting partsareconnected with the deviation adjusting driving part, and the number of the deviation adjusting auxiliary parts and the number of the deviation adjusting parts are the same and are in one-to-one correspondence; and the deviation adjusting auxiliary parts comprise movable ejector rods,the deviation adjusting auxiliary parts are arranged on one side of the machine head body, the ejector rods penetrate through the machine head body from the sides, oppositeto the corresponding deviation adjustingparts, of the machine head body and abuts against the outer mold, the deviation adjusting driving part is used for driving the deviation adjusting parts to move so as to drive the outer mold to moveso as to adjust the concentricity of the outer mold and the core mold, and the ejector rodsareused for being matched with the deviation adjusting parts to support the movement of the outer mold. The invention further discloses an automatic deviation adjusting device. According to the automatic deviation adjusting extruding machine head mold and the automatic deviation adjusting device, the concentricity of the outer mold and the core mold can be automatically adjusted, and the adjusting precision is high.

Description

【Technical field】 [0001] The invention relates to the technical field of mechanical equipment, in particular to an automatic deflection adjustment extruder die and an automatic deflection adjustment device. 【Background technique】 [0002] At present, the reduction of the wall thickness eccentricity of pipe extrusion is achieved by adjusting the concentricity of the outer mold and the mandrel. Generally, after manually observing the eccentricity, manually adjusting the locking screw of the extrusion mold based on experience or feeling, and measuring the wall thickness of the pipe. It is time-consuming and a waste of materials to confirm whether it is qualified in an eccentric state. Especially for the production of pipes with larger or smaller specifications, it often takes a lot of time to adjust continuously to ensure that the wall thickness eccentricity of the extruded pipes is within the standard range, which seriously affects the production efficiency, and the manual adj...

Generally, after manually observing the eccentricity, manually adjusting the locking screw of the extrusion mold based on experience or feeling, and measuring the wall thickness of the pipe. Eccentric state and then confirm whether it is qualified, it is time-consuming and a waste of materials

Especially for the production of pipes with larger or smaller specifications, it often takes a lot of time to adjust continuously to ensure that the wall thickness eccentricity of the extruded pipes is within the standard range, which seriously affects the production efficiency, and the manual adjustment error is large, affecting product quality
