Description

Technical Field

[0001] The utility model relates to the technical field of injection molding equipment, in particular to a device for collecting plastic products after molding. Background Art

[0002] Plastic products are a general term for daily and industrial products made from plastic as the main raw material, including products made from injection molding, blister molding, etc.

[0003] When the injection molding machine produces plastic products, the plastic raw materials may contain some small particles, dust and other impurities. These impurities are crushed during the injection molding process to form fine debris. In addition, under the action of high temperature and pressure, the plastic may degrade and produce some small molecular substances. These substances are crushed during the injection molding process to form fine debris, and will eventually be discharged together with the finished plastic products, so that some debris will be mixed in the plastic products. During the collection process of the products, the debris falls into the collection box together with the plastic products, which is not conducive to the later packaging of the plastic products and will also affect the product quality. Therefore, the Chinese utility model disclosed by the existing publication number CN204725763U Patent: A device for collecting injection molded products, wherein a screening mechanism is added above a material receiving guide plate, the screening mechanism being composed of a screen plate with meshes and a recovery tray. When the corner debris falls into the screening mechanism along with the injection molded product, the debris is small in size and falls from the meshes into the recovery tray arranged parallel to and directly below the screen plate, while the injection molded product that has been separated from the corner debris will not fall into the meshes due to its large size. In this application, by setting a plurality of screen holes in the screen plate, it is difficult for the plastic product to shake out the internal debris when it slides on the screen plate by itself. At the same time, the setting of the screen holes makes it difficult to effectively intercept the debris, and some of the debris will fall into the collection container along with the plastic product, thereby making the screening efficiency of the debris low.
