Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically to a polymer material injection molding machine. Background Technology

[0002] Polymer materials are materials whose main components are polymer compounds. They are formed by the polymerization of many small and simple molecules through chemical reactions. Their structures include linear, branched, and three-dimensional. Polymer material processing technologies include extrusion molding, which is commonly used in the production of plastic pipes and sheets; injection molding, which is widely used in the manufacture of various plastic parts; and calendering, which is mainly used in the production of plastic films and sheets.

[0003] An injection molding machine is a mechanical device used for molding plastics. It heats and melts granular or powdered plastic raw materials, then injects the molten plastic into a mold cavity of a specific shape under high pressure. After cooling and solidification, various plastic products are formed. Injection molding machines are widely used in the plastics processing industry, capable of efficiently and precisely producing plastic products of various specifications and shapes.

[0004] Considering that existing polymer injection molding machines typically use different molds to produce different products, when producing small products, excessive feeding at one time can easily cause excess material to deteriorate due to overheating in the barrel, resulting in material waste. Conversely, when producing large products, insufficient feeding at one time can easily lead to incomplete products due to material shortage, thereby reducing the effectiveness and efficiency of the injection molding machine.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0025] Reference Figures 1 to 3The image shows a polymer injection molding machine, comprising a machine body 1, a feed hopper 2, an adjusting mechanism 3, and a filtering mechanism 4. The feed hopper 2 is fixedly installed on the machine body 1, through which polymer materials are added to the machine body 1 for melt injection. The adjusting mechanism 3 is fixedly installed on the feed hopper 2 and is used to adjust the feeding speed of the feed hopper 2, thereby improving the performance and efficiency of the injection molding machine. The filtering mechanism 4 is inserted into the feed hopper 2 and is used to filter the material added to the feed hopper 2. By filtering the polymer material, other impurities and foreign objects are prevented from entering the machine body 1. The adjusting mechanism 3, which affects the quality of injection molded products, includes a cylindrical tube 33, a moving block 34, and a moving mechanism 38. The cylindrical tube 33 is fixedly installed on the feed hopper 2 by a circular plate 32, which supports and fixes the cylindrical tube 33. The moving block 34 is slidably installed on the cylindrical tube 33. Through the sliding effect of the moving block 34, the position of the moving block 34 in the cylindrical tube 33 can be adjusted, thereby adjusting the actual size of the discharge chute 36 and thus adjusting the feeding speed. The moving mechanism 38 is fixedly installed on the circular plate 32 and is used to drive the moving block 34 to move and adjust the height position of the moving block 34 in the cylindrical tube 33.

[0026] Reference Figures 3 to 5 The adjusting mechanism 3 also includes a funnel 31, a conical block 35, and a rod 37. The funnel 31 is fixedly installed on the feed hopper 2 and is fixedly connected to the circular plate 32. Through the funnel 31, the polymer material can fall into the cylindrical tube 33. The conical block 35 is fixedly installed on the cylindrical tube 33. Through the conical block 35, the polymer material in the cylindrical tube 33 can be guided so that the polymer material can be discharged from the discharge trough 36 into the cylindrical tube 33. The rod 37 is fixedly installed on the moving block 34. Through the rod 37, when the moving block 34 moves, it can drive the rod 37 to clear the polymer material in the circular plate 32 and the funnel 31, avoiding blockage. The cylindrical tube 33 is provided with discharge troughs 36. Multiple discharge troughs 36 are provided to evenly discharge the polymer material in the cylindrical tube 33.

[0027] Reference Figure 4 and Figure 5The moving mechanism 38 includes a connecting rod 381, a fixed block 382, ​​a guide rod 383, and a slider 385. The connecting rod 381 is hinged to the moving block 34 via a hinge column 386. The movement of the connecting rod 381 enables the hinge column 386 to drive the moving block 34 to move vertically. The fixed block 382 is fixedly installed on the circular plate 32. There are two fixed blocks 382. The fixed blocks 382 support the guide rod 383 and the threaded rod 384. The guide rod 383 is fixedly installed on the fixed block 382. The guide rod 383 guides the slider 385. The slider 385 is slidably installed on the guide rod 383 and is hinged to the connecting rod 381. The sliding effect of the slider 385 enables the connecting rod 381 to move. The moving mechanism 38 also includes a threaded rod 384 and a handle 387. The threaded rod 384 is rotatably mounted on the fixed block 382. The rotation of the threaded rod 384 can drive the slider 385 to move. The threaded rod 384 is threadedly connected to the slider 385 and passes through the feed hopper 2. The handle 387 is fixedly mounted on the threaded rod 384. The handle 387 makes it easy for the operator to rotate the threaded rod 384.

[0028] Reference Figure 6 and Figure 7 The filtration mechanism 4 includes a filter cylinder 41 and a U-shaped rod 42. The filter cylinder 41 is inserted into the feed hopper 2. By inserting the filter cylinder 41 into the feed hopper 2, it is convenient to filter polymer materials. The U-shaped rod 42 is fixedly installed on the filter cylinder 41. The U-shaped rod 42 makes it convenient for the staff to pick up the filter cylinder 41. The filter mechanism 4 also includes a stop block 43, a moving ring 45, and a locking block 47. The stop block 43 is fixedly installed on the U-shaped rod 42. The stop block 43 supports and fixes the spring 44. The moving ring 45 is connected to the stop block 43 by the spring 44, and the moving ring 45 is slidably connected to the U-shaped rod 42. Through the elastic force of the spring 44, the moving ring 45 is always engaged with the locking block 47 and the locking groove 48 by the cylindrical rod 46. The locking block 47 is fixedly installed on the moving ring 45 by the cylindrical rod 46. The movement of the moving ring 45 can drive the cylindrical rod 46 and the locking block 47 to move. The feed hopper 2 has a locking groove 48. The locking block 47 engages with the locking groove 48. The engagement of the locking block 47 and the locking groove 48 can limit the filter cylinder 41 and keep the filter cylinder 41 fixed.

[0029] This polymer injection molding machine, through its adjustable and moving mechanisms, can adjust the height of the moving block within the cylindrical tube, thereby adjusting the actual size of the discharge chute and the material feeding speed, thus improving the machine's performance and efficiency. Furthermore, the included filtration mechanism filters the material entering the filter cylinder, preventing other particles and foreign matter from entering the machine body and affecting subsequent melt injection processes, thus reducing product quality.
