Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machine injection, and more specifically, to an injection device of an injection molding machine. Background Art

[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;

[0003] The injection device of the existing injection molding machine often has excessive pressure and a small injection hole during injection, resulting in the hot-melt plastic flowing out through the structure during the injection process, making it difficult to clean and causing waste. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides an injection device for an injection molding machine, which has the advantages of easy cleaning of the outflowing hot-melt plastic and no waste.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an injection device of an injection molding machine, comprising a working bin, a material storage bin is fixedly installed on the left side of the working bin, an injection pipe is fixedly installed on the left side of the material storage bin, a connecting plate is fixedly installed on the surface of the injection pipe, a telescopic rod is fixedly installed on the right side of the connecting plate, a spring is sleeved on the surface of the telescopic rod, and a protective plate is fixedly installed on the left side of the spring.

[0006] As a preferred technical solution of the utility model, a feed port is opened above the working bin, a feed hopper is fixedly installed above the feed port, a sealing plate is fixedly installed on the right side of the working bin, a motor is fixedly installed on the right side of the sealing plate, a heating roller is fixedly installed on the output end of the motor, a guide port is fixedly installed on the left side of the heating roller, and a spiral plate is fixedly installed on the surface of the heating roller.

[0007] As a preferred technical solution of the utility model, there are two telescopic rods and two springs, and the two telescopic rods and the two springs are located outside the injection pipe.

[0008] As a preferred technical solution of the utility model, the storage bin is conical in shape, with a narrow left side and a hollow interior.

[0009] As a preferred technical solution of the utility model, the feed hopper is located directly above the heating roller and the spiral plate, and the interior of the feed hopper is hollow, so a larger volume of plastic particles can be placed therein.

[0010] As a preferred technical solution of the utility model, the heating roller, the guide port and the spiral plate are all located inside the working chamber, and the spiral plate follows the heating roller and is driven by the motor to rotate.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model has a connecting plate fixedly installed on the surface of the injection pipe, a telescopic rod and a spring fixedly installed on the left side of the connecting plate, and a protective plate fixedly installed on the left side of the telescopic rod and the spring, wherein the protective plate is slidably connected to the injection pipe, and the injection pipe is located inside the protective plate. When injection is performed, the protective plate will protect the periphery of the injection pipe, and the protective plate will be tightly attached to the injection molding machine at the other end, thereby effectively preventing the hot-melt plastic from falling and flowing out, thereby achieving the effect of convenient cleaning and no waste.

[0013] 2. The utility model provides a guide port inside the storage bin. When the plastic particles are heated on the surface of the heating roller and become a solution, they will be transported to the inside of the storage bin by the spiral plate for accumulation. When a certain amount of accumulation is reached, they will be discharged from the inside of the injection pipe. Therefore, after injection, no hollowness or bubbles will be generated inside, thereby ensuring the integrity of the injection mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] 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.

[0021] like Figures 1 to 5 As shown, the utility model provides an injection device of an injection molding machine, comprising a working bin 1, a material storage bin 2 is fixedly installed on the left side of the working bin 1, an injection pipe 3 is fixedly installed on the left side of the material storage bin 2, a connecting plate 4 is fixedly installed on the surface of the injection pipe 3, a telescopic rod 5 is fixedly installed on the right side of the connecting plate 4, a spring 6 is sleeved on the surface of the telescopic rod 5, and a protective plate 7 is fixedly installed on the left side of the spring 6;

[0022] The interior of the protective plate 7 is hollow and is slidably connected to the injection pipe 3. Its main function is to prevent the hot-melted plastic from flowing out and falling to the ground, which makes it difficult to clean up.

[0023] A feed port 8 is provided above the working bin 1, a feed hopper 9 is fixedly installed above the feed port 8, a sealing plate 10 is fixedly installed on the right side of the working bin 1, a motor 11 is fixedly installed on the right side of the sealing plate 10, a heating roller 12 is fixedly installed on the output end of the motor 11, a guide port 13 is fixedly installed on the left side of the heating roller 12, and a spiral plate 14 is fixedly installed on the surface of the heating roller 12;

[0024] The heating roller 12 is a horizontally placed cylinder, and its main function is to heat the plastic particles inside so as to melt the plastic and turn the plastic particles into liquid for easy reshaping.

[0025] There are two telescopic rods 5 and two springs 6, and the two telescopic rods 5 and the two springs 6 are located outside the injection pipe 3;

[0026] The two telescopic rods 5 and the two springs 6 mainly function to allow the protective plate 7 to have a certain degree of mobility, and at the same time, during injection, the protective plate 7 can be in closer contact with the machine.

[0027] The storage bin 2 is conical in shape, with a narrow left side and a hollow interior;

[0028] Since the storage bin 2 has a larger internal space and is narrower on the left side, the solution inside can be effectively accumulated, and bubbles may occur during injection, resulting in injection failure.

[0029] The feed hopper 9 is located directly above the heating roller 12 and the spiral plate 14, and the interior of the feed hopper 9 is hollow, so a relatively large volume of plastic particles can be placed therein;

[0030] The main function of the feed hopper 9 is to allow the plastic particles to fall into the surface of the heating roller 12 and the inside of the spiral plate 14 through the feed port 8, thereby achieving the effect of facilitating the discharge of the materials.

[0031] The heating roller 12, the guide port 13 and the spiral plate 14 are all located inside the working chamber 1, and the spiral plate 14 follows the heating roller 12 and is driven by the motor 11 to rotate;

[0032] The main function of the spiral plate 14 is to drive the plastic particles falling into the feed hopper 9 from the right to the left. When the plastic particles become liquid, they can be pushed to the left by the spiral plate 14 and pass through the storage bin 2 to achieve the injection effect.

[0033] The working principle and use process of this utility model:

[0034] First, the device is started to heat the heating roller 12, and at the same time, the motor 11 is started to drive the heating roller 12 and the spiral plate 14 to rotate, so as to achieve the effect of timely heating;

[0035] At this time, the plastic particles are poured into the inside of the feed hopper 9, and fall into the surface of the heating roller 12 and the inside of the spiral plate 14 through the feed port 8. When the plastic particles come into contact with the heating roller 12, the surface of the heating roller 12 is at a high temperature. When the plastic particles are in contact with the heating roller 12 for a long time, they will be melted by heat and become liquid.

[0036] The hot-melt plastic will be pushed to the left by the rotation of the spiral plate 14 and finally accumulated inside the storage bin 2. At the same time, since the guide port 13 has a certain stirring effect on the inside, the hot-melt plastic docked inside the storage bin 2 will not harden and no bubbles will be generated;

[0037] Finally, the hot melt plastic accumulated in the storage bin 2 will be injected into the mold through the injection pipe 3. At this time, the protective plate 7 will be attached to the surface of the injection molding machine to wrap the injection pipe 3, thereby preventing the hot melt plastic from falling and flowing out, achieving the effect of convenient cleaning and no waste.
