Plastic mold for producing mobile phone power adapter and production process

Abstract

The invention discloses a plastic mold for producing a mobile phone power adapter and a production process. The plastic mold comprises an injection mold body, a vibration disc, a rotating disc, a mold drawing plate and a connecting crawler belt, the upper end and the lower end of the injection mold body are fixedly connected with a fixed top plate and a fixed bottom plate correspondingly, and an open groove is formed in the fixed bottom plate. The connecting crawler belt is arranged in the open groove, a driving gear and a driven gear are arranged on the two sides of the interior of the connecting crawler belt correspondingly, a connecting belt is arranged on the surface of the driving gear, and the other end of the connecting belt is in transmission connection with a first driving motor. The vibration disc can be driven to rotate through the motor, so that a vibration head on the surface of the vibration disc makes contact with a vibration plate, the vibration plate vibrates up and down, through the arrangement of the vibrating plate and a vibrating rod, the vibrating plate can drive the vibrating rod to vibrate up and down in a reciprocating mode, the vibrating rod vibrates up and down on plastic in a model pipeline, so that the effect that the plastic in the model pipeline is loosened is achieved.

Description

technical field [0001] The invention relates to the technical field of plastic molds, in particular to a plastic mold for production of a mobile phone power adapter and a production process. Background technique [0002] The power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It is generally composed of housings, transformers, inductors, capacitors, control ICs, PCB boards and other components. Its working principle is converted from AC input to DC output; press the connection Ways can be divided into wall-mounted and desktop. It is widely used in security cameras, set-top boxes, routers, light strips, massagers and other equipment. [0003] Plastic mold is the abbreviation of a combined mold for compression molding, extrusion molding, injection, blow molding and low foam molding. A series of plastic parts of different shapes and sizes can be processed through the coordinated change of the mold convex, concav...

AI Technical Summary

Problems solved by technology

[0005] 1. Most of the plastic molds on the market are currently in use. Due to the high viscosity of the plastic after refining, it is difficult to take out the plastic after cooling and forming in the plastic mold. However, most of them use electric telescopic rods to drive the simple up and down reciprocating movement of the die, which has poor vibration effect and poor release effect;

[0006] 2. During the use of plastic molds, since the injection port is exposed to the outside world for a long time, it is easier to make the surface of the injection port fall into dust. Dust and impurities are brought into the mold, which will affect the plastic molding;

[0007] 3. During the use of plastic molds, due to the high temperature of the plastic after refining, the plastic molds currently on the market generally use natural cooling to cool the plastic, which is a waste of time
