Insulation sleeve injection molding process and matching injection molding machine thereof

Abstract

The invention discloses an insulation sleeve injection molding process. The insulation sleeve injection molding process includes the following steps that 1, a copper wire is straightened; 2, the copper wire is conveyed; 3, mold closing injection molding is carried out, an injection molding machine is started to make a movable mold plate and a static mold plate on the injection molding machine be closed, at the moment, the copper wire penetrates through an injection molding passage formed by the movable mold plate and the static mold plate, and then plastic raw materials are heated and injectedinto the injection molding passage by the injection molding machine; 4, equal distance transmission is conducted, the injection molding machine is started to separate the movable mold plate from thestatic mold plate, then the copper wire continues to be conveyed, so the copper wire is molded to form a section of the insulation sleeve separated from the static mold plate, and the next section ofthe copper wire enters the static mold plate; 5, the third step and the fourth step are repeated, so the rear section of the copper wire is molded to form the insulation sleeve; and 6, the wire is coiled, and in the third step, the copper wire is in sealed connection with the movable mold plate and the static mold plate to prevent molten plastic liquid flowing out of the injection molding passage.The insulation sleeve injection molding process has the following effects of improving the situation that the insulation sleeve is easily separated from the copper wire and facilitating to promote the quality of wire products.

Description

technical field [0001] The invention relates to the field of hardware production, in particular to an insulating sleeve injection molding process and a matching injection molding machine. Background technique [0002] Plugs and wires are common hardware products in daily life. These hardware products usually have a structure of insulating material wrapped on a built-in conductor to prevent people from getting an electric shock when they touch the conductor during use. Insulating materials are often made by injection molding or extrusion. This type of method usually involves heating PVC and other raw materials to a molten state and then injecting them into a specific template or extruding through a specific template to form a specific shape of insulating material products. In the manufacturing process of such hardware products (such as electric wires), the copper wire and the insulating sleeve are usually manufactured separately, and then the insulating sleeve is placed on th...

AI Technical Summary

Problems solved by technology

In addition, it is difficult for the existing injection molding machine to cooperate with the above-mentioned injection molding process to complete the production of the insulating sleeve. Therefore, a matching process for the insulating sleeve injection molding process is urgently needed to complete the technical effect of the above-mentioned injection molding process.
