Injection molding method in power line production system

Abstract

The invention discloses an injection molding method in a power line production system. The injection molding method comprises the following steps of S1, material selecting, wherein a proper quantity of PP is selected as a raw material, and then a proper quantity of antioxygen agent and fire retardant are selected; S2, raw material inspecting, wherein the color, the grain size and the uniformity ofthe PP raw material are inspected, and the quality of the raw material is ensured; S3, drying, wherein the raw material is placed in a stirring drying box from a feeding opening, then a power switchis turned on, drying and stirring can be carried out at the same time, drying is carried out approximately for 10-15 min, and then the raw material is taken out from a discharging opening; S4, barrelcleaning, wherein the temperature of the barrel is increased to the lowest forming temperature of the PP raw material, then the PP raw material is added, continuous air injection is carried out till all residual plastic is cleaned, and the temperature is adjusted to achieve normal production. Compared with other injection molding methods, the technology price is low, space is saved, the process ismature, stress can be resisted, the work efficiency can be effectively improved, the forming effect of power lines can be improved, and safety of users can be guaranteed.

Description

technical field [0001] The invention relates to a power cord production process, and more specifically, to an injection molding method in a power cord production system. Background technique [0002] Power cords are wires that carry electricity. Usually the way of current transmission is point-to-point transmission. Power cords can be divided into AC power cords and DC power cords according to their uses. Usually, AC power cords are wires that pass through high-voltage alternating current. Due to the high voltage, such wires require uniform standards to obtain safety certification before they can be formally produced. The DC line basically passes DC with a lower voltage, so the safety requirements are not as strict as the AC line, but for safety reasons, countries still require unified safety certification. [0003] However, the injection molding method in the traditional power cord production process is relatively simple, and it is very inconvenient to operate. Generally,...

Problems solved by technology

[0003] However, the injection molding method in the traditional power cord production process is relatively simple, and it is very inconvenient to operate. Generally, during injection molding, an oven is used to dry the raw materials directly, but this not only has a bad drying effect, but also reduces work efficiency. Moreover, the power cord produced according to the traditional injection molding method has poor low-temperature impact resistance and is easy to age. The most important thing is that it cannot be steam sterilized, which leads to the safety of the power cord cannot be guaranteed and is not suitable for mass production. Therefore, We propose an injection molding method in a power cord production system
