Abstract
The utility model relates to a pressurizer of a material feeding front chamber of a die casting machine. The pressurizer comprises a pressurizing control oil way assembly and a pressurizing oil cylinder disposed on the material feeding front chamber. The pressurizing oil cylinder is connected with the pressurizing control oil way assembly through a pressurizing control pipeline. The pressurizer comprises a pressurizing oil cylinder used for ensuring the pressure ratio required by the design. The pressurizer further comprises a pressurizing control loop used for ensuring the initial pressure of pressurizing and pressurizing response time. The pressurizer mainly meets the requirements of die casting compact products made by the die casting machine and prevents an injection start segment from having gas rolling.
Description
Technical field
The utility model relates to a kind of supercharging device using in die casting machine equipment technical field, refers in particular to when die casting machine die casting sophisticated product, can prevent a kind of die casting machine dnockout ante-chamber supercharging device of the injection section of beginning volume gas.
Background technology
Along with manufacturing develop rapidly, more and more higher to the quality of die casting and required precision, die casting should have the inside and outside cavity shape of true-to-size, has again good mechanical property.Production practices prove, die casting to fill type intact, clear-cut, depend primarily on injection speed (being injection process), and the internal soundness of die casting and mechanical property mainly sees whether inside has pore.Use the die casting machine of controlling in real time injection system, in the injection section of beginning, due to hydraulic oil compression property, approximately have 15mm injection stroke uncontrollable, have the possibility of volume gas.
Utility model content
The purpose of this utility model is to adopt and control in real time after injection system for traditional die casting machine, in the slow shot section of beginning, has velocity perturbation and produces the phenomenon of rolling up gas, and a kind of dnockout ante-chamber supercharging device structure that can solve above-mentioned weak point is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of dnockout ante-chamber supercharging device of die casting machine, comprise pressurization control oil circuit assembly and be arranged on the installation pressurizing cylinder on dnockout ante-chamber, wherein pressurizing cylinder is connected with pressurization control pipeline with pressurization control oil circuit assembly.
Utilize pressurizing cylinder and its pressurization control loop, the ante-chamber of dnockout (rod chamber) is carried out to supercharging, reduce the velocity perturbation stroke causing because of fluid compressibility;
In the utility model supercharging device, the electric and hydraulic pressure of Pressure elation Control Unit will be connected with the electric and hydraulic system of main frame.
In the utility model supercharging device, pressurizing cylinder will guarantee that dnockout ante-chamber has enough large pressure in use.
In the utility model supercharging device, described supercharging device adopts liquid-liquid supercharging mode.
The utility model, has following beneficial effect: on Pressure elation Control Unit, have pressure-reducing valve, for regulating the inlet pressure of pressurizing cylinder, thereby change the force value after supercharging; There is flow control valve for regulating the response time of supercharging, make supercharging steadily quick; For pressurized cylinder, require the stroke depended on pressure balance of supercharging, rather than control by machinery simultaneously; Each operation cycle, pressurizing cylinder will can advance or retreat under the control of Pressure elation Control Unit.Thereby the steady requirement of the speed that meets die casting machine injection initial segment, is involved in aluminium alloy in case start Duan Youqi.

Fig. 2 is pressurizing cylinder installation diagram of the present utility model, comprises supercharging cylinder body 6, charged piston bar 8, fairlead 10, wherein on supercharging cylinder body 6, has pressurized cylinder oil-in 7 and pressurized cylinder gas returning port 9.
The specific embodiment
The following stated is only a specific embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
The die casting machine of controlling in real time injection system of take is example, during use, first the direction valve V2 in Pressure elation Control Unit obtains electric, pressure oil flows through pressure-reducing valve V1, direction valve V2 and flow control valve V3 from the oil sources of master control liquefaction, again by hydraulic control one-way valve V4, by 1/2 cun of flexible pipe, arrive the pressurized cylinder oil-in 7 of pressurizing cylinder 2, wherein the opposite side of pressurizing cylinder 2 is discharged to fuel tank by pressurized cylinder gas returning port 9 by the air in it again; When the pressure in the chamber, front and back of charged piston bar 8 equates, by stop motion, keep equilibrium of forces.If the pressure of ante-chamber is not enough, the pressure-reducing valve V1 of capable of regulating Pressure elation Control Unit; If supercharging has impact or fast not, the flow control valve V3 of capable of regulating Pressure elation Control Unit.Certainly the pressure size of ante-chamber is to detect by being installed on the pressure sensor of ante-chamber, only has the technological requirement that can meet die casting when the minor fluctuations of dnockout initial velocity, and calculate and adjusts rationally side.
The foregoing is only function of the present utility model and realize explanation introduction; not in order to limit the utility model; any modification of doing within every spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
