Charging wire sheath injection molding method

Abstract

The invention discloses a charging wire sheath injection molding method. Comprising the following steps: S1, preparing a copper ring, enabling the copper ring to penetrate through a wire rod of a charging wire, moving the copper ring to a position where a plug is connected with the wire rod, and reserving a gap of 5-10 mm; s2, the whole charging wire with the copper ring penetrating is put into an injection mold of an injection molding machine, and the copper ring is erected in an injection molding channel and is kept to wait for injection molding; and S3, injection molding is started, injection molding is conducted from the position of the charging wire plug, when injection molding is conducted on the wire rod, an injection molding sizing material can push the copper ring to move outwards till injection molding of the wire rod is completed, and then the copper ring is taken down to complete injection molding of the wire rod. Before injection molding, the copper ring is additionally arranged to penetrate through the wire rod, the copper ring moves along with the injection molding rubber material, the effect of fixing the wire rod is achieved, the wire rod subjected to injection molding is always in the center state, it is guaranteed that the wire rod cannot be exposed to the surface of the injection molding rubber material due to position deviation, the process is simple, injection molding is rapid, and high practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of industrial production fixtures, in particular to an injection molding method for a charging line sheath. Background technique [0002] During the production process of the charging line, after the charging line is initially formed, in order to improve the protection of the charging line, it is necessary to inject plastic on the periphery of the charging line, and wrap a layer of soft rubber around the charging line. [0003] At present, for the injection molding process of the charging line, because the charging line that needs to be injected will have wires, and the length of the wires will be about 100mm, and the wires are very soft. When the wire is injected, the wire bursts out, so that the injected skin cannot completely and evenly wrap the wire. Therefore, most of them are injected by aligning the upper and lower molds. Injection molding the other side, but this injection molding method is easy to ...

[0003] At present, for the injection molding process of the charging line, because the charging line that needs to be injected will have wires, and the length of the wires will be about 100mm, and the wires are very soft. When the wire is injected, the wire bursts out, so that the injected skin cannot completely and evenly wrap the wire. Therefore, most of them are injected by aligning the upper and lower molds. Injection molding the other side, but this injection molding method is easy to produce gaps at the cover, and there are likely to be miscellaneous edges at the cover after the cover, so subsequent grinding is required, thereby increasing redundant production processes
