Abstract
The utility model relates to a double-loop high-speed injection molding machine which adopts an independent hydraulic pressure source to provide a hydraulic support for injection loops, achieves the synchronous operation of the pressure compensation of an energy storage unit and the die opening or die unloading operation, and greatly increases the production efficiency.
Description
Technical field
The utility model relates to a kind of injection machine, especially relates to a kind of double loop high speed injection motding machine.
Background technology
The high speed injection motding machine is meant that mainly injection speed surpasses the injection machine of 300mm/s, and for reaching so high injection speed, the injection loop adopts accumulator to improve injection speed.High speed machine is mainly used to the plastic product of forming superthin wall thickness, the products of wall thickness below 1mm such as for example disposable PP lunch box, sanitary cup, it is little that this series products has a product weight, wall thickness, characteristics such as molding cycle weak point, general molding cycle is between 4 ~ 7 seconds, because this series products wall ratio is less, mould adopts the cooling of frozen water machine basically, and cooling velocity is exceedingly fast, and can realize cooling in die sinking and demoulding flow process; And traditional high speed injection motding machine of this type of product of moulding, in comprising the pressure circuit of injection, injection and other action circuits mostly adopt same hydraulic power source as surging power, on stream, finish after the storing action, before the die sinking, need give the independent repairing of accumulator so that accumulator recovers preset pressure by pump, usually the time and the mold cools down of this repairing process are synchronous, but for need not the thin-wall product of cooling separately, pump switches to the time of this accumulator compensation of accumulator compensation process, become the factor that prolongs process cycle, influenced the raising of productivity ratio.
Summary of the invention
The utility model mainly is to solve existing in prior technology to influence the technical problem that productivity ratio improves, and a kind of double loop high speed injection motding machine is provided.Double loop high speed injection motding machine, it adopts independently hydraulic power source the fluid power support to be provided for the injection loop, accumulator pressure make-up time and die sinking, the demoulding is equal to go on foot carries out, and productivity ratio is greatly improved.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of double loop high speed injection motding machine, the accumulator that it includes oil pump, injection oil cylinder and is connected with its formation pressure compensation, described oil pump is a duplex pump, and one output and injection oil cylinder and accumulator constitute pressure circuit.This structure, make the power fluid potential source in injection loop and separating of other actions, thereby can control separately injection action with and subsequent the energy storage pressure compensation, this pressure compensation process and die sinking, the demoulding are carried out synchronously, reduce the moulding process cycle, reach the purpose of boosting productivity thereby reach.
Need to prove; know-why of the present utility model is by the injection loop is separated with other action circuits; the control injection is moved and is carried out energy storage pressure and compensates separately; therefore; the also available independent hydraulic pump of above-mentioned duplex pump replaces; also can obtain same technique effect, so still belong to protection domain of the present utility model.
Therefore, the utlity model has rational in infrastructure, be easy to make the beneficial effect that especially has higher productivity.
