The invention discloses a hot runner oil pressure open-close pin type injection system. The system includes a columnar oil cylinder A provided with a cylinder body A, which is equipped with a hydraulic oil channel; an oil cylinder B, which is disposed in the cylinder body A and embosoms with the oil cylinder A to form a hydraulic cylinder body internally provided with a piston, and consists of a cylindrical part, an ear part and a cylinder tail, with the piston fixedly connected to the lower end of a piston connecting rod; and an oil cylinder upper cover, which is disposed on the oil cylinder B and is equipped with a main nozzle accommodation cavity, the top of which is equipped with a main nozzle. The bottom of the main nozzle is provided with a main nozzle connecting piece, and the main nozzle is provided with a transverse through hole, where a connection rod is movably disposed. Two connection rod ends stretching out of the through hole are fixedly connected to the upper end of the piston connecting rod. The pin head passes through the main nozzle and the main nozzle connecting piece and is fixed on the connection rod. The injection system provided in the invention can satisfy the casting work of ultrathin wall products and ensure casting efficiency and quality. When the products are added with glass fibers and other fillers, enough pressure can be provided to the pin.
Description
technical field [0001] The invention relates to a hot runner oil pressure opening and closing needle injection molding system. Background technique [0002] For the ultra-thin wall thickness products that appear in the current hot runner injection molding, the conventional design pins cannot work smoothly, and cannot provide customers with qualified products, and the product gate also has unsightly problems; when the product is filled with glass fiber, carbon fiber, etc. When filling, the sealing pressure of the pin is not enough during the filling and holding pressure. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems and provide a hot runner oil pressure opening and closing needle injection molding system. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A hot runner oil pressure opening and closing needle injection molding system, which ...
