Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to an injection molding machine barrel assembly. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are classified as vertical, horizontal, and all-electric. Injection molding machines heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity.

[0003] However, existing injection molding machine barrels are difficult to use to ensure uniform feeding inside, resulting in uneven plasticization of plastic particles after feeding and easy blockage of the barrel connecting pipe. Therefore, it is necessary to provide a new injection molding machine barrel assembly to solve the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide an injection molding machine barrel assembly to overcome the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an injection molding machine barrel assembly, comprising: a fixed cylinder, a fixed plate installed on the top of the fixed cylinder, a conical groove fixedly connected to the bottom of the fixed cylinder, a feed pipe inserted into the upper left side of the fixed cylinder, a connecting pipe fixedly connected to the bottom of the conical groove, and a connecting disc fixedly connected to the bottom of the connecting pipe;

[0006] A uniform feeding mechanism is installed in the middle of the fixed plate, a connecting rod is fixedly connected to the bottom of the uniform feeding mechanism, and an installation plate is installed in the middle of the inner cavity of the fixed cylinder.

[0007] As a further description of the above technical solution: the upper surface of the connecting plate is provided with several mounting holes.

[0008] As a further description of the above technical solution: the uniform feeding mechanism includes a motor installed in the middle of the upper surface of the fixed plate, the power output end of the motor is connected to a rotating shaft, and the motor passes through the fixed plate. A fixed disk is fixedly connected to the bottom of the rotating shaft, and cleaning brushes are installed at the four corners of the outer surface of the fixed disk.

[0009] As a further description of the above technical solution: the cleaning brush is attached to the upper surface of the mounting plate.

[0010] As a further description of the above technical solution: the upper surface of the mounting plate is provided with a plurality of material leakage holes at equal intervals.

[0011] As a further description of the above technical solution: a spiral blade is connected to the bottom outer surface of the connecting rod, and the spiral blade is in contact with the inner wall of the connecting tube.

[0012] This utility model provides a barrel assembly for an injection molding machine. It has the following beneficial effects:

[0013] 1. This application features a uniform feeding mechanism. A motor drives a rotating shaft to rotate, causing the cleaning brush on the fixed plate to rotate. This facilitates the uniform discharge of plastic granules through the discharge holes on the mounting plate. Simultaneously, the rotating shaft also drives the spiral blades on the connecting rod to rotate, ensuring that the plastic granules entering the connecting tube are evenly conveyed into the injection molding machine. This ensures uniform plasticization of the plastic granules, avoids feeding blockages, and improves the stability of the device. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1, Reference Figure 1 and Figure 2This utility model discloses an injection molding machine barrel assembly, which can solve the problem that existing injection molding machine barrels are difficult to ensure uniform feeding inside, resulting in uneven plasticization of plastic particles after feeding and easy blockage of the barrel connecting pipe. It includes a fixed cylinder 1, a fixed plate 2 installed on the top of the fixed cylinder 1, a conical groove 3 fixedly connected to the bottom of the fixed cylinder 1, a feed pipe 4 inserted into the upper left side of the fixed cylinder 1, a connecting pipe 5 fixedly connected to the bottom of the conical groove 3, and a connecting plate 6 fixedly connected to the bottom of the connecting pipe 5.

[0022] The uniform feeding mechanism 8 is installed in the middle of the fixed plate 2. The bottom of the uniform feeding mechanism 8 is fixedly connected to the connecting rod 9. The mounting plate 11 is installed in the middle of the inner cavity of the fixed cylinder 1.

[0023] Working principle: Fixed cylinder 1 and fixed plate 2 facilitate component installation; conical groove 3 allows plastic granules entering the fixed cylinder 1 to slide into the connecting pipe 5 for feeding; feeding pipe 4 facilitates connection with the injection molding machine's feeding mechanism for injecting material into the cylinder; connecting plate 6 and mounting hole 7 facilitate connection between the cylinder and the injection molding machine; uniform feeding mechanism 8 facilitates uniform discharge of plastic granules through the discharge hole 12 on the mounting plate 11; connecting rod 9 facilitates the installation of the spiral blade 10.

[0024] Example 2, refer to Figure 3 and Figure 4 This embodiment solves the problem that existing injection molding machine barrels are difficult to ensure uniform feeding, resulting in uneven plasticization of plastic particles and easy blockage of the barrel connecting pipe. The injection molding machine barrel assembly also includes a plurality of mounting holes 7 on the upper surface of the connecting plate 6, a uniform feeding mechanism 8 including a motor 801 mounted in the middle of the upper surface of the fixed plate 2, a rotating shaft 802 connected to the power output end of the motor 801, and the motor 801 passing through the fixed plate 2. A fixed plate 803 is fixedly connected to the bottom of the rotating shaft 802. Cleaning brushes 804 are installed at the four corners of the outer surface of the fixed plate 803. The cleaning brushes 804 are attached to the upper surface of the mounting plate 11. A plurality of leakage holes 12 are equidistantly opened on the upper surface of the mounting plate 11. A spiral blade 10 is connected to the bottom outer surface of the connecting rod 9. The spiral blade 10 is attached to the inner wall of the connecting pipe 5.

[0025] Working principle: When using this device, after connecting the connecting plate 6 to the injection molding machine, tighten the fixing bolts on the mounting hole 7 to lock the barrel to the injection molding machine. Then, connect the injection molding machine's feeding mechanism to the feeding pipe 4 to feed the fixed cylinder 1. When the plastic particles enter the fixed cylinder 1, they are blocked and buffered by the mounting plate 11. Then, turn on the motor 801, which drives the rotating shaft 802 to rotate, causing the cleaning brush 804 on the fixed plate 803 to rotate. This facilitates the even discharge of the plastic particles through the discharge hole 12 on the mounting plate 11. When the plastic particles fall evenly into the conical groove 3, they slide into the connecting pipe 5 through the inclined surface of the inner wall of the conical groove 3. At the same time, the rotating shaft 802 rotates, driving the spiral blade 10 on the connecting rod 9 to rotate, so that the plastic particles that have entered the connecting pipe 5 are evenly transported into the injection molding machine, ensuring uniform plasticization of the plastic particles, avoiding feeding blockage, and improving the stability of the device.
