Inaccurate feeding will cause fluctuations in the amount of raw materials input, making it difficult to control parameters such as the weight and size of the molded products, thereby affecting the quality stability of the products. Since the amount of raw materials input cannot be accurately controlled, the working parameters of the injection molding machine may be frequently adjusted during the production process, increasing energy consumption and production costs.

[0031] In order to solve this technical problem, the utility model provides a quantitative feeding mechanism for an injection molding machine.

[0032] Specifically, please refer to Figure 1-5The quantitative feeding mechanism of the injection molding machine specifically includes: a frame 1, a driving component 5 and a quantitative component 11. A support plate 2 is fixedly installed on the top of the frame 1, a box body 3 is fixedly installed on the top of the support plate 2, a feed port 4 is opened on the top of the box body 3, a driving component 5 is fixedly installed on the top of the right side of the box body 3, a filter screen 6 is fixedly installed on the left side of the driving component 5, support blocks 7 are fixedly installed on the front and rear sides of the bottom of the filter screen 6, a support rod 8 is slidably installed in the inner cavity of the support block 7, a spring 9 is sleeved on the left side of the surface of the support rod 8, and the side of the spring 9 close to the support block 7 is fixedly connected to the support block 7, a collection shell 10 is fixedly installed in the inner cavity of the box body 3, a quantitative component 11 is fixedly installed on the front side of the bottom right side of the frame 1, a discharge port 12 is opened on the top of the quantitative component 11, and a discharge port 13 is opened at the bottom of the quantitative component 11.

[0033] The quantitative component 11 can be used to feed the injection molding machine quantitatively. Quantitative feeding ensures that the amount of plastic injected into the mold in each cycle is accurate, thereby ensuring the consistency of the weight, size and quality of the molded product. By accurately controlling the input amount of raw materials, the defective and scrap rates of the products can be reduced, and production efficiency and profits can be improved. Quantitative feeding can accurately control the amount of raw materials used, avoid waste caused by excessive input of raw materials, and reduce production costs.

[0034] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0035] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0036] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings. Example

[0037] Please refer to Figure 1-5A quantitative feeding mechanism for an injection molding machine comprises a frame 1, a driving assembly 5 and a quantitative assembly 11. A support plate 2 is fixedly installed on the top of the frame 1, a box body 3 is fixedly installed on the top of the support plate 2, a feed port 4 is provided on the top of the box body 3, a driving assembly 5 is fixedly installed on the top of the right side of the box body 3, a filter screen 6 is fixedly installed on the left side of the driving assembly 5, support blocks 7 are fixedly installed on the front and rear sides of the bottom of the filter screen 6, a support rod 8 is slidably installed in the inner cavity of the support block 7, a spring 9 is sleeved on the left side of the surface of the support rod 8, and the side of the spring 9 close to the support block 7 is fixedly connected to the support block 7, a collection shell 10 is fixedly installed in the inner cavity of the box body 3, a quantitative assembly 11 is fixedly installed on the front side of the bottom right side of the frame 1, a discharge port 12 is provided on the top of the quantitative assembly 11, and a discharge port 13 is provided at the bottom of the quantitative assembly 11. The driving assembly 5 includes a placement plate 501, which is fixedly mounted on the top of the right side of the box body 3, and a bidirectional motor 502 is fixedly mounted on the top of the placement plate 501. Rotating disks 503 are fixedly mounted on the front and rear sides of the bidirectional motor 502. Rotating rods 504 are fixedly mounted on the right sides of the opposite sides of the two rotating disks 503. A connecting plate 505 is movably mounted on the surface of the rotating rod 504. A supporting frame 506 is movably mounted on the left side of the connecting plate 505 through a rotating shaft. The side of the supporting frame 506 close to the filter screen 6 is fixedly connected to the filter screen 6. Fixed plates 507 are fixedly mounted on both sides of the placement plate 501, and the side of the fixed plate 507 close to the placement plate 501 is fixedly connected to the placement plate 501.

[0038] During the implementation process, the plastic particles enter the interior of the box body 3 through the feed port 4. When entering the interior of the box body 3, the plastic particles will pass through the filter screen 6. By starting the bidirectional motor 502, the bidirectional motor 502 will drive the rotating disk 503 to rotate when in use. Then, when the rotating disk 503 rotates, it drives the support frame 506 to move through the rotating rod 504 and the connecting plate 505. When the support frame 506 moves, it drives the filter screen 6 to move, so as to shake and screen the plastic particles, and keep the impurities mixed in the plastic particles on the filter screen 6, while the plastic particles will fall into the aggregate shell 10. The filter screen 6 can effectively filter out impurities in the plastic particles, such as foreign matter, dust, metal fragments, etc., to ensure that the plastic particles in the feeding mechanism of the injection molding machine are clean, which helps to improve the quality and surface finish of the molded products. Example

[0039] The quantitative component 11 includes a driving motor 1101, which is fixedly mounted on the front side of the bottom right side of the frame 1, a first synchronous wheel 1102 is fixedly mounted on the output end of the driving motor 1101, a second synchronous wheel 1104 is arranged on the top of the first synchronous wheel 1102, a belt 1103 is connected between the first synchronous wheel 1102 and the second synchronous wheel 1104, a connecting rod 1105 is fixedly mounted on the inner cavity of the second synchronous wheel 1104, both sides of the connecting rod 1105 are movably mounted on the inner cavity of the frame 1, a quantitative shell 1106 is fixedly mounted on the surface of the connecting rod 1105, and a shell 1107 is arranged on the surface of the quantitative shell 1106. A limiting plate 1108 is sleeved on the surface of the driving motor 1101, and the limiting plate 1108 is fixedly connected to the frame 1 on the side close to the frame 1.

[0040] During the implementation process, the filtered plastic particles enter the interior of the housing 1107 through the discharge port 12, and the drive motor 1101 is started. When in use, the drive motor 1101 drives the first synchronous wheel 1102 to rotate, and when the first synchronous wheel 1102 rotates, the second synchronous wheel 1104 is driven to rotate through the belt 1103, and when the second synchronous wheel 1104 rotates, the quantitative shell 1106 is driven to rotate in the inner cavity of the housing 1107 through the connecting rod 1105. When the plastic particles enter the interior of the housing 1107, because the quantitative groove is at the bottom of the discharge port 12, the plastic particles will enter the quantitative groove on the quantitative shell 1106. When the quantitative groove is full of plastic particles, the next quantitative groove rotates to the bottom of the discharge port 12 to add plastic particles, and the cycle is repeated to achieve quantitative feeding. Quantitative feeding ensures that the amount of plastic injected into the mold in each cycle is accurate, thereby ensuring the consistency of the weight, size and quality of the molded product. The quantitatively completed plastic particles are fed to the injection molding machine through the discharge port 13.

[0041] During installation, plastic particles enter the interior of the box body 3 through the feed port 4. When entering the interior of the box body 3, the plastic particles will pass through the filter screen 6. By starting the bidirectional motor 502, the bidirectional motor 502 will drive the rotating disk 503 to rotate when in use. Then, when the rotating disk 503 rotates, it drives the support frame 506 to move through the rotating rod 504 and the connecting plate 505. When the support frame 506 moves, it drives the filter screen 6 to move, thereby shaking and screening the plastic particles, and the impurities mixed in the plastic particles remain on the filter screen 6, while the plastic particles fall into the aggregate shell 10. The filter screen 6 can effectively filter out impurities in the plastic particles, such as foreign matter, dust, metal fragments, etc., to ensure that the plastic particles in the feeding mechanism of the injection molding machine are clean, which helps to improve the quality and surface finish of the molded products. The filtered plastic particles enter the inner part of the outer shell 1107 through the discharge port 12. The driving motor 1101 is started, and the driving motor 1101 drives the first synchronous wheel 1102 to rotate when in use. When the first synchronous wheel 1102 rotates, the second synchronous wheel 1104 is driven to rotate through the belt 1103. When the second synchronous wheel 1104 rotates, the quantitative shell 1106 is driven to rotate in the inner cavity of the shell 1107 through the connecting rod 1105. When the plastic particles enter the shell 1107, because the quantitative groove is at the bottom of the discharge port 12, the plastic particles will enter the quantitative groove on the quantitative shell 1106. When the quantitative groove is full of plastic particles, the next quantitative groove rotates to the bottom of the discharge port 12 to add plastic particles, and the cycle is repeated in sequence to achieve quantitative feeding. Quantitative feeding ensures that the amount of plastic injected into the mold in each cycle is accurate, thereby ensuring the consistency of the weight, size and quality of the molded product. The quantitatively completed plastic particles are fed to the injection molding machine through the discharge port 13.
