Description

Technical Field

[0001] The utility model relates to the field of charger shell production, in particular to an injection molding machine for producing charger shells. Background Art

[0002] The charger is a charging device that uses high-frequency power supply technology and advanced intelligent dynamic adjustment charging technology. To ensure the safe use of the charging equipment, most chargers are installed with corresponding shells during production to protect the internal structure of the charger. The charger shells are mostly processed by injection molding machines during production.

[0003] Most of the existing charging shell injection molding machines use a fixed mold shell and a movable mold shaping block to cooperate with each other to perform injection molding on the charger shell during production. After the charger shell is molded, the movable mold shaping block is moved to facilitate material removal. During injection molding, plastic solution is mostly filled into the space between the mold shell and the mold shaping block through the injection hole. When the plastic solution solidifies, the plastic solution at the injection hole will also solidify, so that when the movable mold shaping block is reset to prepare for material removal, the molded charger shell is easily stuck in the fixed mold shell, which is inconvenient during material removal. If the molded charger shell is forcibly pulled out or ejected, it is easy to cause a pit in the charger shell at the position of the injection hole, thereby making the molded charger shell a waste.

[0006] An injection molding machine for producing a charger shell comprises a stand, an injection molding mechanism for melting and outputting plastic pellets is installed on the upper end of the stand, and a shaping mechanism for shaping the plastic solution is also included;

[0007] The shaping mechanism includes a base plate, which is fixed to the upper end of one side of the platform, a mold frame is fixed to the upper end of the base plate, an injection hole is opened at one end of the mold frame, an electric push rod is installed in the middle of the base plate, a sliding plate is fixed to the telescopic end of the electric push rod, a mold block is fixed to one end of the sliding plate, a rotating rod is rotatably connected inside the mold block, a gear is fixed to the periphery of the rotating rod, and the upper and lower ends of the gear are engaged with a limit frame.

[0008] Preferably, the sliding plate is slidably connected to the bottom plate, and the limiting frame is slidably connected to the mold block.

[0009] Preferably, a convex strip is arranged on the periphery of one end of the sliding plate, and a rubber layer is arranged on one end of the convex strip, and a groove is arranged on one end of the mold frame corresponding to the shape of the convex strip of the sliding plate.

[0010] Preferably: the injection molding mechanism includes a frame, the frame is fixed at the upper end of the other side of the platform, a feed hopper is fixed at the upper end of the frame, a screw is rotatably connected to the bottom of the frame, a slider is threadedly connected to the outer periphery of the screw, a melt barrel is fixed to the upper end of the slider, a drive rod is rotatably connected to the middle of the melt barrel, a motor is installed at the input end of the drive rod, a spiral frame is fixed to the outer periphery of the drive rod, an insulating shell is fixed to the outer periphery of the output end of the melt barrel, an electric heating frame is installed inside the insulating shell, and an injection molding tube is fixed to the output end of the melt barrel.

[0011] Preferably, the slider is slidably connected to the frame, and an electric heating ring is installed at the output end of the injection molding tube.

[0012] Preferably, the inlet of the melt barrel is located below the outlet of the feed hopper, and the diameter of the inlet of the melt barrel is larger than the diameter of the outlet of the feed hopper.

[0013] The beneficial effects compared with the prior art are as follows:

[0014] When the device is operating, the electric push rod drives the sliding plate to move, so that the mold block extends into the mold frame, and then the gears and the two limit frames are meshed with each other and the mold frame and the limit frame are slidably connected. The rotating rod is rotated counterclockwise to make the two rotating rods move in opposite directions, so that one end of the limit frame exposes the mold block. In this way, when the device is injection molding and solidified, the limit frame can limit the solidified charger shell, and the electric heating structure at the output end of the injection molding mechanism can melt the plastic at the injection hole. In this way, the electric push rod can bring out the molded charger shell when it retracts, and then the rotating rod is rotated clockwise to retract the two limit frames into the mold block, so that the two limit frames do not limit the solidified charger shell, which is convenient for the removal of the charger shell and can also avoid the impact caused by forced removal.
