[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity. The screw is an important part of the injection molding machine. Its function is to transport, compact, melt, stir and pressurize the plastic. All of these are completed by the rotation of the screw in the barrel. When the screw rotates, the plastic will produce friction and mutual movement against the inner wall of the barrel, the bottom surface of the screw groove, the propulsion surface of the screw ridge, and between plastics;

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-4 As shown, a new type of injection molding device includes a supporting component, an injection molding component and a transmission component. The injection molding component is vertically installed on the supporting component, and the injection molding component is connected to the supporting component for injecting plastic into the mold. The transmission component is vertically installed on the injection molding component, and the transmission component is connected to the injection molding component for driving the injection molding component to move. The injection molding component includes a screw 103 and an injection molding barrel 104. The injection molding barrel 104 is installed at one end of the transmission component, and the screw 103 is installed inside the injection molding sleeve. The screw 103 is connected to the injection molding barrel 104 for squeezing out the raw material inside the injection molding barrel 104.

[0021] Specifically, the screw 103 starts to rotate under the drive of the transmission device. As the screw 103 rotates, the plastic material in the injection molding barrel 104 is evenly pushed forward and compressed and heated by the spiral structure of the screw 103. In this process, the plastic material gradually becomes a molten state and fills the interior of the injection molding barrel 104, which facilitates the injection molding of the product to be injected and improves practicality.

[0022] The plastic injection barrel 104 is extended outwardly to be provided with a material pipe 102, which is vertically installed on the plastic injection barrel 104 and connected to the plastic injection barrel 104 for transferring plastic into the plastic injection barrel 104. The plastic injection barrel 104 is extended outwardly to be provided with a hopper 101, which is vertically installed on the plastic injection barrel 104 and connected to the plastic injection barrel 104 for adding plastic raw materials.

[0023] Specifically, first, the operator adds the plastic raw material into the injection molding barrel 104 through the hopper 101. The plastic raw material smoothly enters the injection molding barrel 104 through the material pipe 102 under the action of gravity, thereby improving practicality.

[0024] The injection molding plastic barrel 104 is provided with a nozzle 105 extending outward, and the nozzle 105 is vertically installed on the injection molding plastic barrel 104. The nozzle 105 is connected to the injection molding plastic barrel 104 for discharging the injection molding raw material. The injection molding plastic barrel 104 is provided with a nozzle flange 106 extending outward, and the nozzle flange 106 is sleeved on the outer surface of the injection molding plastic barrel 104. The nozzle flange 106 is connected to the injection molding plastic barrel 104.

[0025] Specifically, when the screw 103 is advanced to a preset position, the nozzle 105 of the injection molding assembly is aligned with the injection hole (not shown) of the fixed mold 303. At this time, the screw 103 continues to advance forward to inject the molten plastic raw material into the fixed mold 303 through the nozzle 105, so as to complete the injection molding when the fixed mold 303 and the movable mold 304 are closed, thereby improving the practicality. At the same time, the setting of the nozzle flange 106 ensures the close connection between the nozzle 105 and the mold, thereby further improving the accuracy and stability of the injection molding.

[0026] A thrust ring 107 is extended outward from the screw 103 and vertically mounted on the screw 103 . The thrust ring 107 is connected to the screw 103 . A sealing ring 108 is extended outward from the injection molding barrel 104 and vertically mounted on the injection molding barrel 104 . The sealing ring 108 is connected to the injection molding barrel 104 .

[0027] Specifically, the thrust ring 107 and the sealing ring 108 play a key sealing role, preventing leakage and contamination of the plastic raw material and improving practicality.

[0028] The transmission assembly includes a first cylinder 301 and a second cylinder 302. The first cylinder 301 is vertically mounted on the support assembly, and the second cylinder 302 is vertically mounted on the support assembly.

[0029] A fixed mold 303 is extended outward from the first cylinder 301, and the fixed mold 303 is vertically installed on the supporting assembly. The fixed mold 303 is connected to the first cylinder 301. A movable mold 304 is extended outward from the second cylinder 302, and the movable mold 304 is vertically installed on the supporting assembly. The movable mold 304 is connected to the second cylinder 302. The injection molding cylinder 104 is located inside the fixed mold 303.

[0030] Specifically, when the product is to be injection molded, the first cylinder 301 and the second cylinder 302 control the opening and closing degree of the fixed mold 303 and the movable mold 304 to ensure that the plastic material in the mold is evenly distributed and fills the entire injection space, thereby improving practicality. When the mold injection is completed and the plastic material is completely cooled and solidified, the first cylinder 301 and the second cylinder 302 drive the fixed mold 303 and the movable mold 304 to open and close again, so that the injection-molded parts can be easily taken out by the operator, thereby improving practicality.

[0031] The supporting assembly includes a protective shell 201 and a workbench 202 . The protective shell 201 is vertically mounted on the workbench 202 . The protective shell 201 is connected to the workbench 202 . The first cylinder 301 and the second cylinder 302 are respectively located on the protective shell 201 . The fixed mold 303 and the movable mold 304 are respectively located on the workbench 202 .

[0032] Specifically, by setting up the protective shell 201, when the injection molding device is in operation, the protective shell 201 will be merged to prevent the excessively high temperature of the plastic material inside the injection molding device from harming the operator. After the mold injection is completed, the protective shell 201 can be opened. By setting up the workbench 202, it is convenient to further support the transmission assembly and the injection molding assembly, thereby improving the stability of the equipment.

[0033] A control box 1 is provided extending outward from the workbench 202 . The control box 1 is vertically mounted on the workbench 202 . The control box 1 is connected to the workbench 202 .

[0034] Specifically, the control system in the control box 1 monitors and adjusts the entire injection molding process in real time, ensuring the normal operation of the equipment and the quality of the injection molded products, thereby improving practicality.
