When using plastic to produce items, a plastic part injection molding device is often used for mass production of plastic products. An injection molding device is a device for manufacturing plastic products and is widely used in various industrial fields. Its working principle is to heat and melt plastic pellets and then inject the molten plastic into a mold under high pressure to form a shape. The injection molding device consists of an injection molding machine, a heating device, an injection system, a mold, a cooling system, and other parts. By precisely controlling the temperature, pressure, and injection speed, the injection molding device can produce high-quality plastic products with complex shapes.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] As Figures 1 - 4 shown, a plastic part injection molding device includes a bracket 1. An injection molding machine main body 9 is installed at the upper end of the bracket 1. The injection molding machine main body 9 is a prior art. The injection molding machine main body 9 is composed of components such as an injection part, a mold clamping part, a hydraulic control part, an electrical control part, a lubrication part, a heating and cooling part, and a safety monitoring part, and is used to manufacture injection molded parts. A top ejection mechanism is provided on the injection molding machine main body 9 for ejecting the injection molded parts after injection molding. A discharge groove 2 is opened on the upper wall of the bracket 1, and a through groove 10 is opened at the right end of the bracket 1. A slide plate 3 is arranged in the discharge groove 2, and a conveyor 4 is arranged in the through groove 10. Cooling components 6 are jointly installed at the upper left part and the upper right part of the upper end of the conveyor 4, and a flipping component 8 is installed in the middle of the upper end of the conveyor 4. The injection molded parts fall from the injection molding machine main body 9 onto the slide plate 3 and then slide onto the conveyor 4. The conveyor 4 drives the injection molded parts to move into the cooling components 6 for cooling operations.

[0025] The cooling components 6 can cool the injection molded parts that are not fully cooled, enabling the workpieces to be fully cooled, facilitating subsequent processing or packaging immediately, reducing the overall production cycle and waiting time, and improving production efficiency. The specific structure is as follows: The cooling components 6 include U-shaped frames 61. There are two U-shaped frames 61 which are distributed left and right. The two U-shaped frames 61 are respectively installed at the upper left part and the upper right part of the upper end of the conveyor 4. A blower 62 is installed at the upper end of the right U-shaped frame 61. Hollow plates 64 are installed on the upper inner walls of the two U-shaped frames 61. The exhaust end of the blower 62 is connected to a connecting pipe 63. The connecting pipe 63 extends into the two hollow plates 64 respectively. A plurality of through holes 65 are opened at the lower ends of the two hollow plates 64. The left hollow plate 64 is used to cool the top of the injection molded parts, and the right hollow plate 64 is used to cool the bottom of the injection molded parts after flanging.

[0026] In order to cool the bottom of the workpiece and further improve the cooling effect, enabling the injection molded part to be completely cooled, the flipping component 8 can drive the workpiece to flip, making the bottom of the workpiece face upward, facilitating the cooling of the bottom of the injection molded part by the hollow plate 64 on the right side. The specific structure is as follows: The flipping component 8 includes vertical plates 81. There are two vertical plates 81, which are distributed front and back. Both vertical plates 81 are installed at the upper end of the conveyor 4. A rotatable connecting shaft 83 is jointly arranged between the two vertical plates 81. A motor 82 is installed at the rear end of the rear vertical plate 81. The motor 82 is a reduction motor, and the motor 82 is in transmission connection with the connecting shaft 83. An electric gripper 84 is fixedly sleeved on the outer surface of the connecting shaft 83. The electric gripper 84 is a prior art and is used to grip both ends of the workpiece.

[0027] An infrared sensor 7 is installed at the upper left middle part of the conveyor 4. The infrared sensor 7 is a prior art and is used to detect whether the injection molded part moves near the flipping component 8.

[0028] Guide rods 5 are installed at the upper left front part and the upper left rear part of the conveyor 4. The two guide rods 5 are symmetrically distributed front and back. The guide rods 5 are used to guide the injection molded part to move to the central part of the conveyor 4, facilitating subsequent cooling and facilitating the flipping component 8 to pick up the injection molded part.

[0029] The slide plate 3 extends above the conveyor 4, and the slide plate 3 is used to guide the workpiece.

[0030] For a plastic part injection molding device proposed by the present utility model, during use, plastic particles are heated and melted, and then the molten plastic is injected into the injection molding machine main body 9 under high pressure. After the injection molding machine main body 9 completes injection molding, the injection molding machine main body 9 ejects the injection molded part. The injection molded part falls onto the slide plate 3 through the discharge chute 2 and slides onto the conveyor 4 through the slide plate 3. The conveyor 4 drives the injection molded part to move into the left U-shaped frame 61. The power of the blower 62 is turned on. The blower 62 conveys external air into the hollow plate 64 through the connecting pipe 63 and then discharges it from the through holes 65, blowing on the surface of the workpiece to cool the injection molding. When moving near the infrared sensor 7, the infrared rays emitted by the infrared sensor 7 are blocked to generate an electrical signal to the controller. The controller controls the electric gripper 84 to grip both sides of the workpiece, and then controls the motor 82 to drive the connecting shaft 83 to rotate. The connecting shaft 83 drives the electric gripper 84 and the workpiece to rotate half a turn, enabling the bottom of the workpiece to face upward. Then it is moved by the conveyor 4 into the right U-shaped frame 61 to cool the bottom of the injection molded part, enabling the injection molded part to be completely cooled. Finally, the cooled injection molded part is moved by the conveyor 4 to each work station.

[0031] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
