Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a flexible automatic grabbing clamp for copper insert injection molding products. Background Art

[0002] During the production process of copper insert pipe joints for household water pipes, the copper inserts need to be placed on the core of the injection mold cavity before injection molding can begin. Due to the requirements of production efficiency, one-mold multi-cavity molds are generally used for production; for the injection molding machine, a fixed type of mold production is used. According to the product mold cavity structure, a copper insert grabbing fixture with the same cavity spacing is used for copper part placement production. Due to the production capacity and order issues of a single product, the same injection molding machine often needs to frequently replace molds of different products. Moreover, the spacing between the mold cavities of different types of copper insert pipe joints is different, resulting in the same injection molding machine. When changing molds of different products, the copper part grabbing fixture with a single spacing cannot be used for other molds, resulting in the inability to automate production.

[0003] At present, when the order volume of copper insert pipe fitting injection molding products is not very large, due to the frequent switching of molds, the inserts can only be placed manually in the mold cavity and then injection molded during injection molding; not only is the labor intensity high and the efficiency low, but also the safety hazards caused by the malfunction of the equipment are easy to occur.

Each clamping cylinder group includes four clamping cylinders 11, and the clamping cylinders 11 in the same clamping cylinder group are connected by a telescopic bracket 12. The slider plates 5 at one end of the two clamping cylinder groups close to the second servo motor 8 are connected by a connecting plate 10, and the connecting plate 10 is connected to the second ball screw 9. An adjustment groove 13 is provided on the end of the connecting plate 10 close to the first servo motor 6, and an adjustment pin 14 is provided in the adjustment groove 13.
