Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to a two-color injection molding machine with a manipulator. Background Art

[0002] At present, the injection molding industry has basically adopted automated manipulators to remove molded parts from the molding mold. The manipulator can automatically remove products with high precision, reduce the defective rate of product costs, ensure the safety of operators, reduce labor, accurately control production volume, and reduce waste. The products formed by the current two-color injection molding machine are generally located inside the molding mold. When removing, the manipulator needs to cooperate with a specific clamping fixture to reach into the mold to synchronously remove the product and the sprue. Such a design requires the manipulator to perform spatial displacement to solve the above problems. In actual use, most of the manipulators are three-axis spatial coordinate manipulators, which can slide on the X, Y, and Z axes respectively. Therefore, during the removal process, three-axis synchronous coordinated movement is required to remove, especially when encountering some molding molds with multiple avoidance positions inside. The product is more difficult, and the movement of the three-axis spatial coordinate manipulator is more complicated, so the control system is also more complicated. Utility Model Content
