Abstract
Description
Technical Field
[0001] The present application relates to the technical field of plastic injection molding, and in particular to an injection molding device for producing plastic products. Background Art
[0002] Plastic products are widely used in many fields such as daily life, industrial production, electronic appliances, etc. due to their excellent properties such as light weight, insulation, and corrosion resistance, such as common plastic containers, plastic toys, and automobile interior plastic parts.

The injection molding equipment is usually composed of an injection molding machine body, a feeding device, an injection molding mechanism and an injection mold. Its working principle is that the plastic raw material first enters the injection molding mechanism through the feeding device. A heating device is arranged inside the injection molding mechanism to heat and melt the plastic raw material to make it flowable. Subsequently, the screw rotates in the injection molding mechanism to push the molten plastic material forward and, under the action of high pressure, is injected into the mold cavity through the gate of the injection mold. After cooling and solidification, it is finally formed into a plastic product.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.
[0024] The following describes the injection molding equipment for producing plastic products according to an embodiment of the present application in conjunction with the accompanying drawings.
[0025] The injection molding equipment for plastic product production provided in the embodiment of the present application can be used in the injection molding process of plastic products, can effectively avoid feed blockage, and can also effectively improve the uniformity of plastic melting and the melting efficiency of plastic raw materials, thereby effectively improving the quality and production efficiency of plastic products.
[0026] like Figure 1-Figure 5 As shown, the injection molding equipment for producing plastic products according to the embodiment of the present application may include an injection molding table 1 , an injection molding mechanism 2 and a feeding assembly 3 .
[0027] The injection molding mechanism 2 and the feeding assembly 3 are respectively arranged on the injection molding platform 1 , and the injection molding mechanism 2 is communicated with the feeding assembly 3 .
[0028] The feeding assembly 3 may include a feeding box 31 , a storage box 32 , a mixing box 33 , a filter plate 34 , a clearing mechanism 35 , an air blowing mechanism 36 , a crushing mechanism 37 and a driving mechanism 38 .
[0029] Among them, the mixing box 33 is fixedly set on the injection molding table 1, the feeding box 31 is fixedly set on the mixing box 33, and the bottom of the feeding box 31 is connected with the top of the mixing box 33, the filter plate 34 is set on the side of the feeding box 31 close to the injection molding mechanism 2, and the filter plate 34 is respectively connected with the injection molding mechanism 2 and the interior of the feeding box 31, the storage box 32 is fixedly set in the feeding box 31, the top of the storage box 32 is open, and a feeding channel is formed at the top of the storage box 32 and between the storage box 32 and the filter plate 34, the blowing mechanism 36 is set on the injection molding table 1, and the blowing mechanism 36 can be rotatably extended into the mixing box 33 and the storage box 32 respectively, the crushing mechanism 37 is set on the blowing mechanism 36, and the crushing mechanism 37 is located in the mixing box 33, and the driving mechanism 38 is set on the injection molding table 1, and the driving mechanism 38 is connected to the blowing mechanism 36.
[0030] It should be noted that a feed hopper 311 is disposed on the top of the feed box 31 described in this embodiment. The feed hopper 311 is in a trumpet shape that is larger at the top and smaller at the bottom, and a sealing cover is also disposed on the top of the feed hopper 311.
[0031] Specifically, the entire injection molding equipment uses the injection molding table 1 as the basic bearing component, and the injection molding mechanism 2 and the feeding assembly 3 are both firmly installed thereon, and the two are interconnected to ensure the continuity of material transportation and injection molding process.
[0032] The feed assembly 3 is the key innovation of the present application. Its components work together to play a core role. The feed box 31 is fixed above the mixing box 33, and the top and bottom of the two are connected, so that the material can naturally fall to the mixing stage by gravity. The filter plate 34 is arranged at the position of the feed box 31 close to the injection molding mechanism 2. It is connected to the feed box 31 and the inside of the injection molding mechanism 2 to screen the feed. It can effectively intercept large particles and agglomerates that may have adverse effects on subsequent processes, and ensure the purity of the material entering the injection molding process. The storage box 32 is built into the feed box 31, and its open top and the feeding channel formed in cooperation with the filter plate 34 provide a precise path for the transportation of materials.
[0033] In one embodiment of the present application, Figure 1-Figure 5 As shown, the dredging mechanism 35 may include a movable plate 351 , a cylinder 352 and a plurality of dredging rods 353 .
[0034] Among them, the movable plate 351 is located between the filter plate 34 and the storage box 32, one end of a plurality of dredging rods 353 is respectively fixedly connected to the movable plate 351, and a plurality of dredging rods 353 are respectively located on one side of the movable plate 351 close to the filter plate 34, the cylinder 352 is arranged on the outer wall of the feed box 31, and the movable end of the cylinder 352 extends into the feed box 31 and is fixedly connected to the movable plate 351.
[0035] Specifically, the dredging mechanism 35 is mainly used to ensure the smooth flow of the filter plate 34. The movable plate 351 is arranged between the filter plate 34 and the storage box 32. One end of a plurality of dredging rods 353 is fixed to the side of the movable plate 351 close to the filter plate 34. The cylinder 352 is used as a power driving component, fixed to the outer wall of the feed box 31, and its movable end extends into the feed box 31 and is connected to the movable plate 351. When the filter plate 34 shows signs of blockage, the cylinder 352 responds in time, drives the movable plate 351 to drive the dredging rods 353 to make reciprocating motion, and cleans the filter holes of the filter plate 34, ensuring that the material can pass continuously and stably, effectively preventing feed blockage.
[0036] In one embodiment of the present application, Figure 1-Figure 5 As shown, the blowing mechanism 36 may include a blower 361 and a blowing shaft 362 .
[0037] Among them, the blower 361 is fixedly installed on the injection molding table 1, one end of the blower shaft 362 is connected to the output shaft of the blower 361, and the other end of the blower shaft 362 is rotatably extended into the mixing box 33 and the storage box 32 through sealed bearings, and the part of the blower shaft 362 located in the mixing box 33 and the storage box 32 is provided with multiple blower nozzles at intervals along the circumferential direction.
[0038] Specifically, the blowing mechanism 36 plays an important role in the entire feeding and mixing process. In the mixing box 33, multiple blowing nozzles are distributed at intervals along the circumference. Under the action of the blower 361, airflow is blown into the mixing box 33, causing the materials in the box to turn over and mix, greatly improving the uniformity of material mixing. In the storage box 32, the airflow blows the material to move to the feeding channel. On the one hand, it can preliminarily mix the material in the storage box 32, and on the other hand, it can continuously feed the material to avoid the material entering the mixing box 33 all at once.
[0039] In addition, the blowing mechanism 36 also delivers the fine particles crushed by the crushing mechanism 37 into the injection molding mechanism 2 through the filter plate 34.
[0040] In one embodiment of the present application, Figure 1-Figure 5 As shown, the crushing mechanism 37 may include a crushing blade holder 371 and a plurality of crushing blades 372 .
[0041] The crushing blade seat 371 is fixedly mounted on the portion of the blower shaft 362 located in the mixing box 33 , and a plurality of crushing blades 372 are evenly distributed on the crushing blade seat 371 along the circumferential direction.
[0042] Specifically, when the blast shaft 362 rotates under the drive mechanism 38, the crushing blade 372 rotates at a high speed to crush the agglomerated or large-particle raw materials, ensuring that the particle size of the materials entering the subsequent process is uniform, creating conditions for the uniformity of plastic melting.
[0043] In one embodiment of the present application, Figure 1-Figure 5 As shown, the driving mechanism 38 may include a driving motor 381 and a belt transmission mechanism 382 .
[0044] The driving motor 381 is fixedly mounted on the injection molding table 1 , and the belt transmission mechanism 382 is transmission-disposed on the output shaft of the driving motor 381 and the blower shaft 362 .
[0045] Specifically, the drive motor 381 is installed on the injection molding table 1, and the belt transmission mechanism 382 connects the output shaft of the drive motor 381 and the blower shaft 362. Through the belt transmission, the power of the drive motor 381 is stably transmitted to the blower shaft 362 to ensure the orderly coordination of the blowing, crushing and other actions.
[0046] Specifically, after the production of plastic products starts, the plastic raw materials are first poured into the feed hopper 311. With the help of its trumpet-shaped structure, the raw materials quickly gather into the feed box 31. At this time, the storage box 32 plays a preliminary buffering role, and the raw materials stay in the storage box 32. At the same time, the driving mechanism 38 is started, and the driving motor 381 drives the belt transmission mechanism 382 to operate, prompting the blowing shaft 362 of the blowing mechanism 36 to rotate at a high speed. The blowing shaft 362 extends into the mixing box 33, and the blowing nozzle thereon blows air into the mixing box 33, so that the raw materials in the mixing box 33 are stirred and tumbled to achieve preliminary mixing, and the part extending into the storage box 32 helps the raw materials to be transported to the filter plate 34 through airflow changes.
[0047] When the raw materials arrive at the filter plate 34, the filter plate 34 performs screening, and only small particles of raw materials that meet the requirements are allowed to pass through the injection molding mechanism 2, and large particles of impurities and lumps are intercepted. Once the filter plate 34 is at risk of being blocked, the cylinder 352 of the unblocking mechanism 35 is immediately started, pushing the movable plate 351 to drive the unblocking rod 353 to clean the filter plate 34 to ensure smooth feeding. The movable plate 351 can also achieve a sealing effect on the filter plate 34.
[0048] In the mixing box 33, as the blowing mechanism 36 continues to operate, the crushing blade 372 of the crushing mechanism 37 rotates synchronously at a high speed to crush the agglomerated or large-particle raw materials in real time, ensuring that the particle size of the raw materials entering the injection molding mechanism 2 is uniform and fully mixed, thereby effectively improving the uniformity of plastic melting and the melting efficiency of the plastic raw materials. After the raw materials pretreated as above enter the injection molding mechanism 2, according to the traditional heating, screw pushing and other processes in the injection molding mechanism 2, the subsequent processes such as melting and high-pressure injection molding are completed, and finally high-quality plastic products are produced.
[0049] In summary, the injection molding equipment for plastic product production according to the embodiment of the present application can effectively avoid feed blockage, and can also effectively improve the uniformity of plastic melting and the melting efficiency of plastic raw materials, thereby effectively improving the quality and production efficiency of plastic products.
