[0032] Embodiment 2 (built-in metal mesh injection molding method to produce plastic distribution cabinet):

[0033] (a) According to the shape of the power distribution cabinet, the power distribution cabinet is divided into two parts, the front door and the rear shell. The front door is a single door, and the front door and the rear shell of the plastic power distribution cabinet are opened and molded.

[0034] (b) Add the gray flame-retardant nylon resin into the hopper of the injection molding machine, the temperature of the baking material is 100° C., and the drying time is 4 hours.

[0035] (c) Cut the barbed wire mesh with a wire diameter of 0.2mm and a mesh number of 80 meshes into a mesh with a size similar to the inner surface area of ​​the injection molding mold.

[0036] (d) Put the cut barbed wire into the mold of the injection molding machine, turn on the injection molding machine, adjust the temperature of the first stage of the plastic machine to 230°C, the tem...

Embodiment 3

[0039] Embodiment 3 (production of plastic distribution cabinet by molding method):

[0040] (a) According to the shape of the power distribution cabinet, the power distribution cabinet is divided into two parts, the front door and the rear shell.

[0041] (b) Feed the gray flame-retardant polypropylene resin into the hopper of the sheet material extruder, control the temperature of the first stage of the extruder to 240°C, the second stage to 230°C, the third stage to 220°C, and the fourth stage to 210°C, A flame-retardant polypropylene sheet with a thickness of 2 mm was prepared.

Abstract

The invention relates to a plastic power distribution cabinet. The plastic power distribution cabinet is mainly manufactured by manufacturing a front door and a back shell of the plastic power distribution cabinet by performing injection molding or compression molding on a flame-retardant polypropylene resin or a flame-retardant nylon resin or a polyvinyl chloride resin and metal meshes (or manufacturing a front door and a back shell of the plastic power distribution cabinet by performing injection molding on a flame-retardant polypropylene resin or a flame-retardant nylon resin or a polyvinyl chloride resin and glass fiber meshes) and assembling the front door and the back shell by using a plastic hinge. The plastic power distribution cabinet has the characteristics of high insulating property, flame resistance, light weight, paint-free property, aging resistance and low production cost and is widely applied to power distribution systems of power plants, communication departments and enterprises and public institutions.

Description

Technical field [0001] The invention belongs to the technical field of electrical equipment manufacturing, and relates to a production technology of a plastic distribution cabinet. Background technique [0002] At present, the power distribution cabinets on the market are all iron-shell power distribution cabinets. The production method is to open a stamping mold, then stamp the white iron sheet into shape, and then degrease the stamped parts, wash them with water, pickle them, wash them with water, and wash them with alkali. , water washing, surface adjustment, phosphating, scalding, drying, and painting to make the power distribution cabinet components, and finally assemble the power distribution cabinet components into a complete power distribution cabinet with hinges. The disadvantage of this kind of distribution cabinet is that the insulation performance is not good, the line is easy to short circuit, the product is relatively heavy, and the installation is inconvenient...
