Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to an automatic product gate removal device for taking out parts from an injection molding machine. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastic plastics or thermosetting plastics. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it ejected and fill the mold cavity. Among them, the "a demoulding and material taking device for injection molded parts with inner buckles" disclosed in the application number "CN214687769U" has solved the problem that when the existing injection molded parts with inner buckles are demoulded and taken out, the injection molded parts have not been completely cooled, resulting in their surface viscosity being still in an active state, which may cause them to adhere to the mold and be difficult to remove during demoulding. In addition, the injection molding environment temperature is high, the space is small, it is difficult to take them out manually, and it is easy to get burned. There are many disadvantages of certain safety hazards. After further retrieval, it was found that the application number "CN214687769U" 7169617U" disclosed in the "Automatic Discharging Device for Lens Injection Molding Production", through a specific technical structure setting, effectively solves the problem that although the existing automatic material-retrieving machines have improved efficiency, some of them have unstable material-retrieving problems. For example, when the weight of the lens group is large, the material may accidentally fall off during the retrieving process. In addition, many automatic material-retrieving machines are specially customized for specific injection molding machines, and have technical disadvantages such as a narrow scope of application. However, in actual use, an automatic product gate removal device for taking out parts from an injection molding machine with a similar structure still has many defects, such as: most of the existing injection molding machine parts are manually taken out after injection molding, and there is a lack of automatic clamping mechanism, and most of the parts after injection molding have gates, which need to be manually cut off, which is time-consuming and labor-intensive. Therefore, it is necessary to design an automatic product gate removal device for taking out parts from an injection molding machine. Utility Model Content

[0003] The utility model aims to provide an automatic product gate removal device for taking out parts from an injection molding machine, so as to solve the problems raised in the above-mentioned background technology.
