Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to an injection molding device for producing plastic composite materials. Background Art

[0002] Injection molding is a method of producing industrial products. The injection molding process is to inject molten plastic into a mold through an injection molding device to form plastic or rubber products of various shapes.

[0003] For example, an injection molding device disclosed in Chinese patent CN216910957U mainly solves the following problems: a filter plate is provided to prevent unmelted plastic particles from entering the outer conveying tube; a feeding tray is provided in the outer conveying tube to further prevent the discharge of insufficiently melted plastics and thus affect the quality of the products; a spiral heating tube is provided on the outer wall of the outer conveying tube to prevent the outer surface layer of the molten material from condensing in the outer conveying tube, thereby blocking the feeding tray; an exhaust pipe is provided on the outer barrel, and the exhaust pipe is connected to the liquid barrel containing the treatment liquid to treat the irritating gas generated during the melting process and prevent direct discharge that endangers human health.

[0004] The injection molding device filters the particles through the filter and transports them to the outer tube, which affects the injection molding quality. However, the stirring device in the injection molding device is fixed and can only stir and flow the material at the bottom of the inner barrel. The material at the top is not stirred by the stirring blades because it is far away from the stirring blades, which leads to uneven heating of the material and retention of a large number of particles. Therefore, it takes a longer time to hot melt, which reduces the efficiency of the injection molding work. Utility Model Content

[0005] The utility model aims to provide an injection molding device for the production of plastic composite materials, which solves the problem that the stirring device in the injection molding device is fixed and can only stir and flow the material at the bottom of the inner barrel, while the material at the top thereof cannot be stirred because it is far away from the stirring blade, thereby causing uneven heating of the material and retaining a large number of particles, so that a longer time is required for hot melting, thereby reducing the efficiency of the injection molding work.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an injection molding device for producing plastic composite materials, comprising a supporting base plate;

[0010] Preferably, the discharging adjustment mechanism includes a discharging box that is connected and arranged at the bottom end of the supporting base plate, the inner wall of the discharging box is slidably connected with an adjusting block, the outer wall of the adjusting block is fixedly connected with a push rod, the outer wall of the push rod movably passes through the outer wall of the discharging box, the outer wall of the push rod away from the adjusting block is fixedly connected with a fixing ring, the fixing ring is fixedly connected with an end of the discharging box close to the discharging box, the second spring is fixedly connected to the outer wall of the discharging box at one end away from the fixing ring, the outer wall of the fixing ring is fixedly connected with a force rod, the top end of the force rod is contacted with one end of an electric telescopic rod, and one end of the electric telescopic rod is fixedly connected to the outer wall of the pushing rotating rod.

[0011] Preferably, there are two support plates, which are symmetrically distributed on the top of the support base plate.

[0012] Preferably, a slope is provided at the top end of the force-bearing rod, and an outer wall of the slope is in contact with the output end of the electric telescopic rod.

[0014] Preferably, the outer wall of the regulating block fits snugly with the inner wall of the discharge box.

[0015] The utility model provides an injection molding device for producing a plastic composite material. The injection molding device for producing a plastic composite material has the following beneficial effects:

[0016] (1) The injection molding device for producing plastic composite materials starts the motor to drive the rotating rod to rotate, and the rotating rod drives the stirring blade to rotate, so as to stir and mix the materials and flow. At the same time, the rotation of the rotating rod drives the pushing rotating rod to rotate, thereby driving the first protrusion to rotate. The first protrusion rotates and can contact and be squeezed by the second protrusion. The squeezed first protrusion can drive the motor and the rotating rod to move upward through the sliding connection between the supporting slide rod and the slide rod, and at the same time drive the first spring to stretch. When the two protrusions are no longer in contact, the first spring can rebound and reset, thereby driving the motor and the rotating rod to move downward. In this way, the rotating rod and the stirring blade can be repeatedly driven to move up and down, thereby increasing the stirring range and improving the uniform mixing of the materials.

[0017] (2) The injection molding device for the production of plastic composite materials starts the electric telescopic rod to drive the output end to contact the outer wall of the force-bearing rod, then turns off the motor, and then starts the electric telescopic rod again according to the capacity of the material to be discharged, thereby driving the force-bearing rod to move. The movement of the force-bearing rod can drive the push rod and the adjustment block to move on the inner wall of the discharge box, so that the capacity inside the discharge box can be adjusted to control the discharge amount. After the material is discharged from the outer wall, the discharge valve at the bottom of the discharge box is opened, and the material flows into the injection cylinder at the bottom to complete the injection molding.
