Injection molding automatic production line for plastic chair and plastic chair production method

Abstract

The invention provides an injection molding automatic production line for a plastic chair, and the production line comprises an electric control cabinet, an inlaying and taking-out clamp, an injectionmolding machine, an injection mold assembled on the injection molding machine, a screw and nut combination machine and a multi-axis robot, wherein the screw and nut combination machine and the multi-axis robot are located beside the injection molding machine. The multi-axis robot is further arranged adjacent to the screw and nut combination machine. The electric control cabinet is electrically connected with the inlaying and taking-out clamp, the injection molding machine, the screw and nut combination machine and the multi-axis robot; the inlaying and taking-out clamp is assembled and connected with the output end of the multi-axis robot; and the inlaying and taking-out clamp takes away the screw and nut assembly combined by the screw and nut assembly machine under the driving of the multi-axis robot, takes out the plastic chair left in one of the fixed mold and the movable mold in the injection mold after the mold is opened, and embeds the taken-out screw and nut assembly into the other one of a fixed mold and a movable mold in the injection mold after the mold is opened. The production efficiency is improved, and the number of operators is reduced. In addition, the invention further discloses a production method of the plastic chair.

Description

technical field [0001] The invention relates to the field of plastic chair production, in particular to a method for realizing the automatic combination of screws and nuts, embedding the screw and nut assembly in the injection mold in one injection mold opening, and taking away the plastic chair in the injection mold Plastic chair injection molding automatic production line and plastic chair production method. Background technique [0002] With the continuous development of the economy and the continuous progress of the society, various material consumer goods are provided for people's lives to enrich people's living standards, and plastic products are one of many material consumer goods. [0003] As we all know, the cooperation of injection molding machine and injection mold is the most commonly used method for manufacturing plastic products. Among them, for the plastic chair with the screw and nut assembly formed by the assembly of screws and nuts, the manufacturing proce...

Problems solved by technology

[0004] However, in the existing plastic chairs that are foreseen to be embedded with screw and nut assemblies, the embedding of the screw and nut assemblies into the injection mold and the removal of the plastic chair in the injection mold are performed by two independent feeding manipulators and It is completed by the unloading manipulator. Because the loading manipulator and the unloading manipulator are independent of each other and occupy a large space, the loading manipulator embeds the assembly in the injection mold and the unloading manipulator takes out the molded product from the injection mold. It cannot be carried out at the same time. That is to say, after the feeding manipulator finishes embedding and withdraws, the unloading manipulator takes out the molded product, so the work continuity is poor

At the same time, the screw and nut assemblies need to be manually assembled by operators in advance, so the degree of automation is poor, thereby reducing production efficiency
