Description

Technical Field

[0001] This utility model relates to the field of injection molding machine hopper technology, specifically to an injection molding machine hopper and an injection molding machine. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to make various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. Injection molding machines heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity. Usually, injection molding machines have a barrel for storing plastic raw materials, and the barrel is equipped with a hopper, which is the injection molding machine hopper. The injection molding machine hopper is a container for storing granular raw materials. When using an injection molding machine, it needs to be fed. Generally, the injection molding raw materials are added to the hopper and then added to the injection tube through the hopper.

[0003] For example, Chinese Patent Publication No. CN211389882U describes an injection molding machine hopper and an injection molding machine, which includes a hopper body and a connecting square tube for connecting with injection molding machine components. The hopper body is provided with a cover, which is threadedly connected to the hopper body. A butterfly valve is provided between the hopper body and the connecting square tube, and both the hopper body and the connecting square tube are fixedly connected to the butterfly valve. The hopper body and the connecting square tube are connected through the butterfly valve. The hopper body is provided with an installation port, which is connected to the interior of the hopper body. A discharge groove for sealing itself is inserted into the installation port. One end of the discharge groove is hinged to the hopper body, and the other end of the discharge groove is detachably connected to the hopper body. The discharge groove is transparent.

[0004] The existing technology has the following problems: when adding plastic raw materials to the injection tube, the plastic raw materials are prone to blockage when falling due to the lower discharge pipe of the hopper, which affects the overall injection process. Also, when unloading into the injection molding machine, the plastic raw materials rely on natural rolling, which leaves plastic raw material residue in the hopper and unloading components, thus reducing the utilization efficiency of the hopper.

[0013] A further improvement of this utility model is that the vibration rebound assembly includes a vibration motor detachably installed on the inner wall of the bottom surface of the discharge pipe away from the movable connector. The output end of the vibration motor is fixedly connected to a connecting plate. The top of the connecting plate is movably connected to the bottom surface of the discharge inclined plate. A rebound piece is fixedly connected to the inner cavity of the top of the connecting plate and fixedly connected to the bottom surface of the discharge inclined plate. Through the arrangement of the vibration motor and the connecting plate, and in conjunction with the vibration of the rebound piece and the discharge inclined plate caused by elasticity and vibration force, the flow of plastic raw materials in the discharge pipe is assisted.

[0025] The present invention will be further described in detail below with reference to embodiments:

[0026] Example

[0027] like Figure 1-5 As shown, this utility model provides an injection molding machine hopper, including: a hopper body 1; a filling port 2 fixedly installed on the top of the hopper body 1; an anti-blocking mechanism 3 installed on the hopper body 1; a discharge pipe 4 fixedly connected to the bottom of the hopper body 1; and a vibration discharge mechanism 5 disposed on the bottom surface of the inner cavity of the discharge pipe 4. The anti-blocking mechanism 3 includes a driving component fixedly installed on the hopper body 1, and the output end of the driving component is fixedly connected to an anti-blocking stirring component disposed inside the hopper body 1. The vibration discharge mechanism 5 includes an inclined discharge component rotatably installed on the inner wall of the discharge pipe 4, and the bottom of the inclined discharge component is provided with a detachable... The vibratory rebound assembly 52, installed on the inner wall of the bottom surface of the discharge pipe 4, applies vibration force to the plastic raw material using the vibratory discharge mechanism 5 to assist in the discharge of the plastic raw material. The hopper body 1 includes a hopper body 11, a top cover 12 detachably installed on the top of the hopper body 11, a discharge pipe 13 fixedly connected to the bottom surface of the hopper body 11, and a solenoid valve for controlling the discharge installed on the discharge pipe 13. The bottom surface of the filling port 2 is fixedly connected to the top of the top cover 12. The anti-blocking mechanism 3 agitates the plastic raw material in the hopper body 11 to prevent the plastic raw material from accumulating in the hopper body 11 and to prevent blockage when discharging from the discharge pipe 13.

[0028] Furthermore, in this embodiment, the driving component includes a drive motor 31 whose bottom surface is fixedly connected to the upper surface of the top cover 12. The output shaft of the drive motor 31 passes through the top cover 12 and is rotatably connected to the inner wall of the top cover 12. A coupling rotatably connected to the middle of the bottom surface of the top cover 12 is fixedly connected to the output shaft of the drive motor 31. The anti-blocking and stirring component includes a main rotating rod 32 fixedly connected to the bottom surface of the coupling. A distributing rod 33 is welded to the outer surface of the main rotating rod 32, and the distributing rods 33 are evenly distributed on the outer surface of the main rotating rod 32. An auxiliary rod is fixedly connected to the bottom surface of the main rotating rod 32. A horizontal plate 35 is fixedly connected to the outer surface of the rotating rod 34 and the auxiliary rotating rod 34. The outer surface of the horizontal plate 35 is rotatably connected to the inner surface of the discharge pipe 13. The outer surface of the dispensing rod 33 is rotatably connected to the inner surface of the bucket body 11. The output shaft of the drive motor 31 drives the main rotating rod 32 to rotate, which in turn drives the dispensing rod 33 to rotate. The dispensing rod 33 stirs the plastic material in the bucket body 11, causing it to be affected and put into motion. Then, the rotation of the auxiliary rotating rod 34 and the horizontal plate 35 is used to stir the plastic material falling and discharged at the discharge pipe 13, so that the plastic material falls in a flowing state.

[0029] Furthermore, in this embodiment, the inclined feeding component includes a discharge inclined plate 51 whose outer surface is movably connected to the inner surface of the discharge pipe 4. A movable connecting member 53 is fixedly connected to the bottom surface of the outer end of the discharge inclined plate 51.

Both ends of the movable connecting member 53 are rotatably connected to the inner wall of the discharge pipe 4. The vibration rebound assembly 52 includes a vibration motor 521 detachably installed on the inner wall of the bottom surface of the discharge pipe 4 at the end away from the movable connecting member 53. The output end of 1 is fixedly connected to a connecting plate 522. The top of the connecting plate 522 is movably connected to the bottom surface of the discharge ramp 51. A spring sheet 523, which is fixedly connected to the bottom surface of the discharge ramp 51, is fixedly connected to the top inner cavity of the connecting plate 522. Through the vibration of the vibration motor 521 and the cooperation of the connecting plate 522, the spring sheet 523 and the discharge ramp 51 shake due to elasticity and vibration force, which assists the flow of plastic raw materials in the discharge pipe 4 and reduces the amount of plastic raw materials remaining before entering the injection molding machine.

[0030] In addition, this utility model also provides an injection molding machine, including the injection molding machine hopper described above.

[0031] The following is a detailed explanation of the hopper and working principle of the injection molding machine.

[0032] like Figure 1-5As shown, during use, plastic raw materials are first poured into the hopper 11 through the filling port 2. When it is necessary to inject material into the injection molding machine, the solenoid valve on the discharge pipe 13 is opened, and the drive motor 31 and the vibration motor 521 are started at the same time. The output shaft of the drive motor 31 drives the main rotating rod 32 to rotate, which in turn drives the distributing rod 33 and the auxiliary rotating rod 34 to rotate. The distributing rod 33 and the horizontal plate 35 are used to stir the plastic raw materials, causing them to be in motion. The plastic raw materials are discharged from the discharge pipe 13 into the unloading pipe 4. At this time, the vibration of the vibration motor 521 and the connecting plate 522, along with the elasticity and vibration of the rebound plate 523 and the discharge inclined plate 51, help the plastic raw materials to flow in the unloading pipe 4 and assist the plastic raw materials to be quickly transported into the injection molding machine for processing.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
