Abstract
The utility model discloses an automatic centering extrusion die, which comprises an outer die sleeve and an inner die core, wherein an extrusion channel is formed between the outer side of the front end of the inner die core and a discharge port of the outer die sleeve, a centering inclined plane is arranged on the outer side of the rear end of the inner die core, the centering sleeve is sleeved on the outer side of the inner die core, and the centering inclined plane is consistent with the inclination of a positioning hole of the centering sleeve; the rear end of the inner mold core is arranged in the through hole of the positioning seat, and an elastic layer is arranged between the outer side of the rear end of the inner mold core and the through hole of the positioning seat. The utility model has the advantages that: the inner mold core is abutted to the positioning hole of the centering sleeve by utilizing the reaction force generated when the plastic is extruded, the centering sleeve and the positioning seat are fixed into a whole, and the inner mold core and the outer mold sleeve are fixed after debugging before extrusion, so that the inner mold core always ensures centering, and the thickness uniformity of the outer insulating layer is further ensured.
Description
Technical Field
The utility model relates to a manufacturing technical field of cable, a cable crust extrusion tooling specifically says so.
Background
The inner part of the cable is a metal conductor, the outer layer of the cable is a plastic insulating skin, and hot-melt plastic is covered on a metal conductor passing through the center of a die through an extrusion die generally; in the process of manufacturing the cable, the requirement on the thickness of the insulating sheath covered by the outer layer is high, because the quality of the cable is directly influenced if the thickness of the insulating layer is not uniform. The existing extrusion dies are not provided with an automatic centering structure, so that the problem that the outer side insulation thickness is uneven due to extrusion deviation of an inner die core of the die is very easy to occur when the extrusion die is used.
Disclosure of Invention
In order to solve the technical problem, the utility model aims at providing a can automatic alignment centering extrude mould, concrete technical scheme as follows:
an automatic centering extrusion die comprises an outer die sleeve and an inner die core, wherein an extrusion channel is formed between the outer side of the front end of the inner die core and a discharge hole of the outer die sleeve, a centering inclined plane is arranged on the outer side of the rear end of the inner die core, the centering sleeve is sleeved on the outer side of the inner die core in a penetrating manner, and the inclination of the centering inclined plane is consistent with that of a positioning hole of the centering sleeve; the rear end of the inner mold core is arranged in the through hole of the positioning seat, and an elastic layer is arranged between the outer side of the rear end of the inner mold core and the through hole of the positioning seat.
The radial outer side of the centering sleeve is abutted against the inner side of the fixing ring, the fixing ring and the positioning seat are of an integral structure, and the centering sleeve and the positioning seat are fixed into a whole by the fixing screw.
The included angle between the centering inclined plane and the horizontal plane is 3-5 degrees.
The utility model has the advantages that: the inner mold core is abutted to the positioning hole of the centering sleeve by utilizing the reaction force generated when the plastic is extruded, the centering sleeve and the positioning seat are fixed into a whole, and the inner mold core and the outer mold sleeve are fixed after debugging before extrusion, so that the inner mold core always ensures centering, and the thickness uniformity of the outer insulating layer is further ensured.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings, wherein the front end refers to the right side of fig. 1, and the rear end refers to the left side of fig. 1. As shown in the figure, the utility model comprises an outer die sleeve 1 and an inner die core 3, wherein an extrusion channel 4 is formed between the outer side of the front end of the inner die core 3 and a discharge hole of the outer die sleeve, and the extrusion channel 4 corresponds to an output end 2 of an extruder so as to ensure that hot-melt plastics flow out through the extrusion channel 4;
a centering inclined plane 9 is arranged on the outer side of the rear end of the inner mold core 3, a centering sleeve 10 is sleeved on the outer side of the inner mold core 3 in a penetrating manner, and the inclination of the centering inclined plane 9 is consistent with that of a positioning hole 11 of the centering sleeve 10; the rear end of the inner mold core is arranged in the through hole of the positioning seat 7, an elastic layer 8 is arranged between the outer side of the rear end of the inner mold core 3 and the through hole of the positioning seat, and the elastic layer can be made of rubber.
The radial outer side of the centering sleeve 10 is abutted against the inner side of the fixing ring 13, the fixing ring 13 and the positioning seat 7 are of an integral structure and can be processed into an integral structure, the metal wire 6 is arranged in the central through hole 5 of the positioning seat, and the centering sleeve and the positioning seat are fixed into a whole by the fixing screw 12.
The included angle between the centering inclined plane and the horizontal plane is 3-5 degrees.
In operation, plastic flows along the direction of an arrow a, and the metal wire moves along the direction of an arrow b; the inner mold core 3 is abutted to the positioning hole 11 of the centering sleeve 10 by utilizing the reaction force F when the plastic is extruded, the centering sleeve and the positioning seat are fixed into a whole, and the centering sleeve and the outer mold sleeve are fixed after debugging before extrusion, so that the inner mold core always ensures centering, and the thickness uniformity of the outer insulating layer is further ensured.
