Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to a plastic production injection molding machine. Background Technology

[0002] With the booming development of the plastics industry, injection molding machines, as the core equipment for molding plastic products, are increasingly widely used in various industries. Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment for making various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molding molds. They are divided into vertical, horizontal, and all-electric types. Injection molding machines can heat plastics and apply high pressure to molten plastics, causing them to be injected and fill the mold cavity.

[0003] Currently, most injection molding machines do not filter the raw materials during feeding. Impurities mixed in with the plastic raw materials are not filtered out before entering the injection molding machine. When the plastic raw materials are melted and molded under high pressure, black spots or impurities will appear on the surface of the product, resulting in substandard quality of the finished plastic product. To address this, we propose a new type of plastic production injection molding machine. Utility Model Content

[0004] The purpose of this utility model is to provide a plastic injection molding machine to solve the problem that most existing injection molding machines do not filter the raw materials during feeding. Impurities mixed in with the plastic raw materials are not filtered out before entering the injection molding machine, which leads to black spots or impurities on the surface of the product during high-pressure molding of the plastic raw materials, resulting in substandard quality of the finished plastic products.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic injection molding machine, including a mounting frame, a fixing plate fixedly mounted on the upper end of the mounting frame, a horizontal injection molding machine and a mold fixedly mounted on the surface of the fixing plate, a feeding assembly and a filtering assembly fixedly mounted on the surface of the mounting frame, the feeding assembly including a plastic storage box fixedly mounted on the surface of the mounting frame, the plastic storage box having a conveying pipe fixedly mounted on it via a pump body, the filtering assembly including a filter box fixedly mounted on the top of the mounting frame and a feed hopper on the top of the horizontal injection molding machine, the end of the conveying pipe away from the pump body passing through the upper end of the filter box and extending into the interior of the filter box.

[0006] As a preferred embodiment, the filter box is fixedly installed with a first filter plate and a second filter plate from top to bottom, and the bottom outlet of the filter box is located inside the feed hopper.

[0007] As a preferred embodiment, a heating coil arranged in a spiral is fixedly installed on the inner wall of the feeding hopper, and an electric valve is provided at the bottom of the feeding hopper where it connects to the horizontal injection molding machine.

[0008] As a preferred embodiment, a collecting component is fixedly installed on the surface of the mounting bracket and below the fixing plate, and a feeding groove is provided on one side of the fixing plate and at the mold, and a pull-out plate is slidably connected inside the feeding groove.

[0009] As a preferred embodiment, the collection assembly includes a base plate and a collection box fixedly installed on the surface of the mounting frame. A fixing frame is fixedly installed on the surface of the base plate. An inclined slide and a crushing box are fixedly installed on the left and right ends of the fixing frame, respectively. A top cover is detachably installed on the top of the crushing box.

[0010] As a preferred embodiment, one end of the inclined slide is fixedly installed at the bottom of the fixing plate and below the feeding trough, while the other end is fixedly installed inside the crushing box. A feeding plate is fixedly installed at the right end of the fixing frame and below the crushing box. A drive motor is fixedly installed at the center of the bottom surface of the crushing box. Multiple sets of crushing blades are fixedly installed on the output shaft of the drive motor. A discharge port is opened on the bottom surface inside the crushing box. The feeding plate is inclined and its bottom end is fixedly installed at the top of the collecting box.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] By setting up a feeding component and a filtering component, the plastic storage box stores the raw materials, the pump body drives the conveying pipe to feed the materials, the conveying pipe passes through the filtering box, and the materials are filtered and purified by the first and second filter plates in the box. After purification, the raw materials enter the feeding hopper, and the spiral heating coil on the inner wall of the feeding hopper preheats and softens the raw materials, reducing the main heating load of the horizontal injection molding machine and making the raw materials more uniformly plasticized. Combined with the high-pressure injection of the horizontal injection molding machine, the product quality is improved.

[0013] By setting up a collection component, after the mold is opened, the finished product and waste fall onto the pull plate. After the finished product is picked up manually, the pull plate is pulled, and the waste slides into the inclined slide through the feeding chute. The slide is automatically transported to the crushing box, and the drive motor drives the crushing blades to crush the waste into small particles. The particles fall into the collection box through the discharge port and the inclined feeding plate, realizing the waste volume reduction and recycling, and reducing raw material waste.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see the appendix Figure 1 - Appendix Figure 4 A plastic injection molding machine includes a mounting frame 1. A fixing plate 2 is fixedly mounted on the upper end of the mounting frame 1. A horizontal injection molding machine 3 and a mold 4 are fixedly mounted on the surface of the fixing plate 2. A feeding assembly 5 and a filtering assembly 6 are fixedly mounted on the surface of the mounting frame 1. The feeding assembly 5 includes a plastic storage box 501 fixedly mounted on the surface of the mounting frame 1. A conveying pipe 503 is fixedly mounted on the plastic storage box 501 through a pump body 502. The filtering assembly 6 includes a filtering box 601 fixedly mounted on the top of the mounting frame 1 and a feeding hopper 602 on the top of the horizontal injection molding machine 3. The end of the conveying pipe 503 away from the pump body 502 passes through the upper end of the filtering box 601 and extends into the interior of the filtering box 601. The mounting frame 1 serves as a basic support, integrating the horizontal injection molding machine 3 and the mold 4 through the upper fixing plate 2. The feeding assembly 5 and the filtering assembly 6 are simultaneously mounted to construct a complete injection molding production unit. The components work together in an orderly manner to ensure a continuous injection molding process and improve equipment integration and space utilization.

[0022] Inside the filter box 601, a first filter plate 603 and a second filter plate 604 are fixedly installed from top to bottom. The bottom outlet of the filter box 601 is located inside the feed hopper 602. In the feeding assembly 5, the plastic storage box 501 stores the raw materials. The pump body 502 drives the conveying pipe 503 to accurately feed the raw materials. The conveying pipe 503 passes through the filter box 601, so that the raw materials are filtered before entering the feed hopper 602, forming a closed loop of storage, feeding and filtration. This avoids impurities from affecting subsequent injection molding and ensures the cleanliness of the raw materials. The first filter plate 603 and the second filter plate 604 in the filter box 601 intercept the raw materials conveyed by the conveying pipe 503 from top to bottom, performing two-stage filtration to effectively remove particulate impurities, metal scraps, etc., greatly improving the purity of the raw materials entering the feed hopper 602 and reducing the risk of wear between the mold 4 and the injection molding machine screw.

[0023] A spiral heating coil 605 is fixedly installed on the inner wall of the feed hopper 602, and an electric valve is provided at the bottom of the feed hopper 602 where it connects to the horizontal injection molding machine 3. The spiral heating coil 605 on the inner wall of the feed hopper 602 can preheat and soften the raw material before it enters the horizontal injection molding machine 3, start the plasticizing process in advance, reduce the load on the main heating system of the injection molding machine, save energy, and make the raw material plasticize more uniformly. Combined with high-pressure injection, it helps to improve the molding accuracy of the product.

[0024] Specifically, the plastic storage box 501 stores the raw materials, and the pump body 502 drives the conveying pipe 503 to precisely feed the materials. The conveying pipe 503 extends through the filter box 601 into the interior, realizing a continuous process from material storage to material feeding. The first filter plate 603 and the second filter plate 604 are installed sequentially from top to bottom in the filter box 601 to perform two-stage filtration on the plastic raw materials conveyed by the conveying pipe 503. This can effectively intercept impurities in the raw materials and improve the purity of the raw materials entering the feed hopper 602. The spiral heating coil 605 on the inner wall of the feed hopper 602 can preheat the raw materials before they enter the horizontal injection molding machine 3, so that the raw materials are softened in advance, reducing the workload of the main heating system of the horizontal injection molding machine 3. At the same time, preheating makes the plasticization of the raw materials more uniform, which, together with the high-pressure injection of the horizontal injection molding machine 3, improves the product quality.

[0025] Please see the appendix Figure 1 - Appendix Figure 3 and appendix Figure 5 A collection component 7 is fixedly installed on the surface of the mounting frame 1 and below the fixing plate 2. A material discharge groove 8 is opened on one side of the fixing plate 2 and at the mold 4. A pull plate 9 is slidably connected inside the material discharge groove 8. The collection component 7 on the surface of the mounting frame 1 cooperates with the material discharge groove 8 and the pull plate 9 of the fixing plate 2. After the mold 4 is opened, the finished product and waste material fall onto the pull plate 9. After the finished product is picked up manually, the pull plate 9 can controllably unload the material. The waste material is guided by the inclined slide 704 through the material discharge groove 8 to realize automated unloading and pre-collection management.

[0026] The collection component 7 includes a base plate 701 and a collection box 702 fixedly installed on the surface of the mounting frame 1. A fixing frame 703 is fixedly installed on the surface of the base plate 701. An inclined slide 704 and a crushing box 705 are fixedly installed on the left and right ends of the fixing frame 703, respectively. A top cover is detachably installed on the top of the crushing box 705.

[0027] One end of the inclined slide 704 is fixedly installed at the bottom of the fixed plate 2 and below the feeding trough 8, while the other end is fixedly installed inside the crushing box 705. A feeding plate 706 is fixedly installed at the right end of the fixed frame 703 and below the crushing box 705. A drive motor 709 is fixedly installed at the center of the bottom surface of the crushing box 705. Multiple sets of crushing blades 707 are fixedly installed on the output shaft of the drive motor 709. A discharge port 708 is opened on the bottom surface of the crushing box 705. The feeding plate 706 is inclined and its bottom end is fixedly installed at the upper end of the collection box 702. The inclined slide 704 receives waste and transports it to the crushing box 705. The drive motor 709 drives the crushing blades 707 to crush at high speed, breaking large-volume waste into small particles. The particles are discharged into the collection box 702 through the discharge port 708 and the inclined feeding plate 706, realizing waste volume reduction storage and convenient recycling, and reducing raw material waste.

[0028] Specifically, the collection component 7 on the surface of the mounting frame 1, together with the feeding trough 8 and the pull plate 9 on the fixing plate 2, after the mold 4 is opened, the finished product or waste material falls onto the pull plate 9. The finished product is picked up, and the pull plate 9 is pulled. The waste material slides into the inclined slide 704 through the feeding trough 8. The pull plate 9 can control the feeding timing and flow rate as needed. One end of the inclined slide 704 is connected to the feeding trough 8 of the fixing plate 2, and the other end is connected to the crushing box 705. It can be automatically transported to the crushing box 705 without manual intervention. The drive motor 709 drives the crushing blade 707 to rotate at high speed, crushing the waste or defective products entering the crushing box 705 in real time, breaking large-volume waste into small particles, which fall into the inclined feeding plate 706 through the discharge port 708 and slide into the collection box 702. This reduces the space occupied by waste material, facilitates subsequent recycling, and reduces the waste rate of raw materials.

[0029] The working principle of this utility model is as follows: This utility model is a plastic injection molding machine. When the equipment is running, the feeding component 5 first works, and the raw materials stored in the plastic storage box 501 are transported through the conveying pipe 503 under the drive of the pump body 502. The conveying pipe 503 passes through the filter box 601. After the raw materials enter the filter box 601, they are filtered in two stages by the first filter plate 603 and the second filter plate 604 to intercept impurities. The pure raw materials fall into the feed hopper 602. The spiral heating coil 605 on the inner wall of the feed hopper 602 preheats and softens the raw materials, reducing the main heating load of the horizontal injection molding machine 3 and allowing the raw materials to... The plasticization is more uniform. Then the electric valve is opened, and the raw material enters the horizontal injection molding machine 3. After heating and high pressure, it is injected into the cavity of the mold 4 for molding. After the mold 4 is opened, the finished product or waste falls onto the pull plate 9. The finished product is picked up manually and the pull plate 9 is pulled. The waste slides into the inclined slide 704 through the discharge chute 8 and is automatically transported to the crushing box 705. The drive motor 709 drives the crushing blade 707 to rotate at high speed, crushing the waste. It falls into the inclined discharge plate 706 through the discharge port 708 and finally slides into the collection box 702 to realize the recycling and treatment of waste, completing the entire injection molding production process. At this point, the entire process ends.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
