Technical field
The utility model relates to a kind of injector, particularly a kind of improved injector shaped device.
Background technology
Known rubber injection machine generally comprises frame and is located at injection device and shaped device on the frame, described shaped device comprises cover half, dynamic model, die cylinder, some leads etc., described cover half is fixed on the frame, dynamic model is located on each lead movably, and the cylinder body of die cylinder and valve rod are affixed with frame and dynamic model respectively.Injection molding the time, thereby described die cylinder with dynamic model push to cover half make cover half and dynamic model mutually the closure between form forming cavity, injection device advances closely and with rubber injection to go in the forming cavity to forming cavity then, through pressurize moulding after a while, described dynamic model is descending die sinking under the effect of die cylinder, and the stripper apparatus of being located on the cover half ejects the moulding that forming cavity is finished rubber parts with the rubber parts of forming.Known die cylinder has two kinds, a kind ofly form side by side by at least two small-bore die cylinders, this kind oil cylinder closure pressing speed is fast, but because frequent die sinking and the matched moulds of die cylinder, make oil pressure be difficult to keep the scope of setting, be that locked mode is under-voltage, cause forming cavity slurry in the mould when injection or pressurize to overflow thus, cause the rubber parts overlap from the slit between cover half and the dynamic model; Another kind of structure is to adopt single bigbore die cylinder, this kind die cylinder can satisfy the requirement of locked mode pressure, but because the cylinder diameter of oil cylinder is too big, the speed of hydraulic oil filling die cylinder is relatively slow, therefore required time is longer in matched moulds, causes the production efficiency of whole injection device on the low side.
The utility model content
The purpose of this utility model is to provide that a kind of closure pressing speed is fast, the reliable improved injector shaped device of locked mode.
The technical scheme that the utility model adopted is such: a kind of improved injector shaped device, comprise frame, cover half, dynamic model, die cylinder and some leads, described cover half is fixedly arranged on the frame, each lead is parallel to be located on the frame, dynamic model is located on each lead movably, the cylinder body of die cylinder and valve rod are affixed with frame and dynamic model respectively, frame is provided with pressurize oil cylinder and hydraulic oil container, described pressurize oil cylinder is made up of cylinder body and piston rod, described piston rod one end and dynamic model are affixed, the piston rod other end is positioned at the cylinder body medial compartment and forms the pressurize oil pocket with pressurize effect with cylinder body, be provided with in-line and oil return line between described pressurize oil pocket and the hydraulic oil container, described in-line is provided with check valve, and oil return line is provided with magnetic valve, and described pressurize oil pocket also is connected with the oil-out of an oil pump.
Above-mentioned improved injector shaped device, described lead are four and rectangular array.
Above-mentioned improved injector shaped device, described pressurize oil cylinder is located at the middle part of four leads.
Above-mentioned improved injector shaped device, described die cylinder and pressurize oil cylinder are connected in the oil-out of same oil pump.
Above-mentioned improved injector shaped device is provided with sealing ring between described piston rod and the cylinder body.
Above-mentioned improved injector shaped device is provided with fairlead between described piston rod and the cylinder body.
Above-mentioned improved injector shaped device is provided with dust ring between described piston rod and the cylinder body.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: described die cylinder can make dynamic model engage with cover half apace and form forming cavity in order to the injection device injection, piston rod fast rise under the drive of dynamic model of the oil cylinder of pressurize simultaneously, because the suction function of pressurize oil pocket is opened check valve, hydraulic oil in the hydraulic oil container enters the pressurize oil pocket fast, and in the pressurize oil pocket, setting up dwell pressure under the drive of oil pump, make cover half and dynamic model tightly fasten, thereby make plastic rubber shaping spare be unlikely the generation overlap, each shape is filled full, and shaping speed is fast.
