When the automotive interior plaque basic unit processing shaping is needed, the controller controls the electric telescopic rod 28 to start to drive the movable mould 27 to move towards the static mould 26, until the movable mould 27 contacts with the static mould 26, the movable mould 27 and the static mould 26 form a shaping cavity, at the moment, two conducting plates 214 contact, the circuit is conducted, the current is conveyed to the hydraulic push rod 212 through the conducting plates 214, the current direction of the hydraulic push rod 212 is changed, at the moment, the hydraulic push rod 212 stretches out, at the same time, when the material to be melted enters the melting pipe 23 through the feeding port of the melting pipe 23, the controller controls the electric heating plate 24 to heat the material to melt, and at the same time, the controller controls the motor 21 to start to drive the spiral auger 22 to rotate to convey the melted material into the extrusion pipe 25, at the moment, the hydraulic push rod 212 pushes the extrusion plate 213 to move downwards, overcomes the attractive force between the magnets and pulls the expansion joint 211 to stretch downwards, thereby driving the piston 210 to move downwards synchronously, and extruding the melted material at the bottom of the extrusion pipe 25 into the shaping cavity formed by the movable mould 27 and the static mould 26, and carrying out the shaping process.
When the extrusion plate 213 drives the piston 210 to move downwards through the expansion joint 211, the piston 210 pulls the rack 32 to slide upwards through the pulling rope, so as to drive the gear 33 meshed with the piston to rotate, the shifting post 34 on the gear 33 rotates synchronously, the special-shaped wheel 35 is shifted in the rotating process of the shifting post 34, so that the special-shaped wheel 35 is driven to rotate and periodically extrude the plugging plate 36, the plugging plate 36 compresses the spring 37 and opens the plugging of the connecting pipe 31, thereby providing a flow passage for air between the static die 26 and the film, the air enters the gas collecting tank 29 through the connecting pipe 31 under the action of pressure difference, the extrusion is stopped after the extrusion plate 213 extrudes a fixed amount of molten material, at the moment, the special-shaped wheel 35 does not extrude the plugging plate 36 any more, the plugging plate 36 plugs the connecting pipe 31 again under the restoring force of the spring 37, so that a vacuum environment is formed between the static mold 26 and the film, the adsorption film is tightly attached to the surface of the static mold 26, when the molded inner decoration plate base layer is required to be demolded after injection molding, the controller controls the electric telescopic rod 28 to drive the movable mold 27 to move rightwards, the two conductive plates 214 are separated from contact, the hydraulic push rod 212 is restored to the initial current direction, the hydraulic push rod starts to shrink and drives the extrusion plate 213 to move upwards, the piston 210 is pushed to move upwards under the transmission effect of the telescopic joint 211, the rack 32 slides downwards, the special-shaped wheel 35 is driven to rotate reversely under the effect of the gear 33 and the shifting column 34, the extrusion blocking plate 36 compresses the spring 37 again, so that the channel between the connecting pipe 31 and the cavity of the static mold 26 is opened again, the gas inside the gas collecting box 29 is extruded and the film is blown along the connecting pipe 31 again, the automobile inner decoration plate molded on the outer surface of the film is separated, thereby realizing the rapid demoulding of the base layer of the inner decorative plate.
When the movable mould 27 contacts with the static mould 26, the controller controls the water pump 42 to work to pump out water in the water tank 41, the water is conveyed into the cavity of the movable mould 27 through the circulating water pipe 43 to cool the melted material in the forming cavity, the forming efficiency of the base layer of the interior decorative plate is improved, the water after heat absorption returns into the water tank 41 again from the circulating water pipe 43, the water after heat absorption is cooled under the action of the refrigerating plate 44, the water in the water tank 41 is kept at a low temperature all the time, and therefore the movable mould 27 is continuously cooled, and the forming efficiency is guaranteed.
