Embodiment 1

[0025] An extrusion processing mold capable of improving the stripping force of automobile electric wires, comprising a mold sleeve 1 and a mold core 3, an extrusion channel 7 is opened at the right end of the mold sleeve 1, an inner mold 16 is arranged between the mold sleeve 1 and the mold core 3, and an inner mold 16 is arranged between the mold sleeve 1 and the mold core 3. The shape of the mold 16 is the same as that of the inner wall of the die sleeve 1. The right end of the inner mold 16 is provided with an extrusion tube 10 located in the extrusion channel 7. The extrusion tube 10 is covered with a sleeve 9. There are a number of ring grooves 12, bearings 11 are arranged in the ring grooves 12, and connecting blocks 13 extending into the ring grooves 12 and connecting with the bearings 11 are arranged on the inner wall of the sleeve 9, and the outer wall of the sleeve 9 and the inner wall of the extrusion channel 7 pass through The threaded connection is matched, and th...

Embodiment 2

[0031] This embodiment improves on the basis of Embodiment 1:

[0032] The inner walls of the upper and lower sides of the mold case 1 are provided with through holes 5 horizontally, and the outer walls of the inner mold 16 are provided with pillars 4 extending into the through holes 5 .

[0033] The advantages of the above improvements are: as part of the extrusion pressure of the insulating material will be applied to the inner mold, and the original inner mold only has the connection and constraint between the extrusion tube and the mold sleeve, the extrusion pressure will cause the rest of the inner mold to Some parts are not very stable in the vertical direction, so the cooperation between the pillar and the through hole is used to ensure the stability of the inner mold in the vertical direction.

Embodiment 3

[0035] This embodiment improves on the basis of Embodiment 1:

[0036] The through hole 5 is an internal screw hole, and an external screw rod 6 is arranged in the through hole 5. One end of the external screw rod 6 extends to the outside of the mold cover 1, and the end of the external screw rod 6 extending to the outside of the mold cover 1 is connected with a rotary operation block 14.

[0037] The advantages of the above improvements are: by using the thread fit between the outer screw and the through hole, the end of the outer screw can be rotated to make contact with the end of the pillar, and the pillar can be limited and restrained. When the wire is processed, the constraint of the outer screw can be used to offset the impact of the insulating material. The pressure of the inner mold further ensures the stability of the inner mold in the horizontal direction.

Abstract

The invention discloses an extrusion processing mold capable of improving the automobile electric wire stripping force, and relates to the technical field of electric wire cable production equipment.The extrusion processing mold solves the problems that the existing electric wire extrusion processing mold changes the electric wire stripping force through angle regulation, but the angle regulationhas trouble and has limitation. The extrusion processing mold comprises a mold sleeve and a mold core, wherein an extrusion passage is arranged at the right end of the mold sleeve; an inner mold is arranged between the mold sleeve and the mold core; the inner mold shape is the same as the mold sleeve inner wall shape; an extrusion pipe positioned in the extrusion passage is arranged at the rightend of the inner mold; a sleeve is sleeved outside the extrusion pipe; a plurality of annular grooves are formed in the circumferential direction of the outer wall of the extrusion pipe; a bearing isarranged in the annular groove; a connecting clamp block which extends into the annular groove and is connected with the bearing is arranged on the inner wall of the sleeve; the outer wall of the sleeve and the inner wall of the extrusion passage are connected and matched through screw threads; the length of the sleeve is greater than the length of the extrusion passage.

Description

technical field [0001] The invention relates to the technical field of wire and cable production equipment, and more specifically relates to an extrusion processing die that can improve the stripping force of automobile wires. Background technique [0002] In the middle of the nineteenth century, the second industrial revolution flourished, and mankind entered the electrical age. Up to now, electric energy has become one of the most important energy sources for human beings. As a carrier of electric energy, wires and cables are widely used in various fields of life. The current wires are covered with an outer insulating material layer to cover the inner metal conductor, which improves the safety of the wires during use. [0003] The maximum force required for peeling between the insulating material layer and the metal conductor is called the peeling force. If the peeling force is too small, the insulating material layer and the metal conductor are easily separated, which is ...
