Abstract
The utility model relates to a novel press ejection structure. The novel press ejection structure comprises a press injection piston rod, wherein a press injection cylinder partition sleeve is arranged at the front end of the press injection piston rod, a lifting sliding block and a press injection oil way block are arranged outside the press injection cylinder partition sleeve, the press injection piston rod is connected with a pressurizing piston rod in a matched mode, a pressurizing piston rod guide sleeve is arranged at the front end of the pressurizing piston rod, a pressurizing piston is arranged at the rear end of the pressurizing piston rod, and a pressuring oil way block is arranged outside the pressurizing piston rod. The novel press ejection structure is high in reliability, pressurizing is rapid, the press injection route is not changed, and the length of a press injection cylinder is reduced, and materials are saved.
Description
Technical field
The utility model relates to a kind of injection structure, is specifically related to a kind of valve body injection structure.
Background technique
At present, the Proportional valve on the market is various.Proportional valve claims operated proportional flow control valve again, and it is to regulate pro rata and the flow of stable oil circuit by electrical signal, thereby changes a kind of valve of actuator's movement velocity.Electro-hydraulic proportional valve is that the proportion electro-magnet input voltage signal produces corresponding actions in the valve, makes spool produce displacement, and port size changes and finishes and the proportional pressure of input voltage with this.Wherein, the injection structure is particularly important, and there are defectives such as poor reliability in old-fashioned injection structure.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, a kind of reliability height to be provided, and supercharging is fast, and the injection stroke is constant, and injection cylinder length shortens, the novel injection structure of material-saving.
Technological scheme: in order to solve the problems of the technologies described above, a kind of novel injection structure described in the utility model, it comprises shot piston, be provided with the injection cylinder spacer at described shot piston front end, be respectively equipped with lifting slider and injection manifold block in described injection cylinder spacer outside, described shot piston and charged piston bar are connected, be provided with charged piston rod guidance cover at described charged piston bar front end, be provided with charged piston at described charged piston rod rear end, be provided with the Pressure Increasing Oil-Line piece in described charged piston bar outside.
Described injection manifold block closely is connected with the Pressure Increasing Oil-Line piece.
Between described injection manifold block and Pressure Increasing Oil-Line piece, be provided with described charged piston rod guidance cover.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model overall structure is simple, it is better to be used effect between each parts, the requirement of realistic production process has solved the variety of issue of former existence, the reliability height, supercharging is fast, the injection stroke is constant, and injection cylinder length shortens, material-saving.
