As shown in fig. 6, the storage is penetrated gate valve oil cylinder 44 and includes that gate valve cylinder block 441 is penetrated in storage and gate valve cylinder putter is penetrated in storage 442, the storage is penetrated gate valve cylinder putter 442 and penetrates valve core for gate valve 432 and be connected with the storage, drives described storage to penetrate valve core for gate valve 432 It is mobile, carry out conducting state switching.

The injection gate valve 46 includes injecting gate valve seat 461 and injection valve core for gate valve 462；When the injection valve core for gate valve 462 be located at position as shown in Figure 7 when, the injection gate valve 46 is closed, and the passage being attached thereto is not turned on, when the injection lock When valve core 462 is located at position as shown in Figure 9, the injection gate valve 46 is opened, and top is turned on the passage 45, bottom Turn on injection structure.

The injection gate valve oil cylinder 47 includes injecting gate valve cylinder block 471 and injection gate valve cylinder putter 472, the note Penetrate gate valve cylinder putter 472 to be connected with the injection valve core for gate valve 462, drive the injection valve core for gate valve 462 to move, realize institute State the open and close of injection gate valve 46.

The storage to be penetrated and be also respectively provided with least one heating on gate valve 43, the passage 45 and the injection gate valve 46 Device, for the injection melt continuous heating, being kept molten by the injection melt moment.

The storage is penetrated gate valve 43 and be also respectively provided with temperature-sensing element on gate valve 46 with described injection, for real-time monitoring Temperature conditionss in pipeline.

The storage to be penetrated and be respectively arranged with cooling water pipe on gate valve cylinder block 441 and the injection gate valve cylinder block 471 , there is oil leakage phenomenon, and scald operator in road, for cooling down to cylinder body, it is to avoid temperature is too high to cause sealed ring deformation Member.

The storage is penetrated, and causes to scald for preventing operator from surprisingly touching.

It is continuous feeding state during due to the compounding arrangement works, can continuously extrudes the injection melt, and Injection structure is service intermittent state, and after often injecting once, mould can all have one section of dwell time.So needing for continuously not The injection melt that cut-off comes arranges an interim storage space.Transformational structure is penetrated when the injection melt flows into the storage When, if the injection structure charge is finished, the injection gate valve 46 is closed under the drive of the injection gate valve oil cylinder 47, together When, the storage is penetrated gate valve 43 and is moved to position as shown in Figure 8 in the drive that gate valve oil cylinder 44 is penetrated in the storage, and the injection is melted After the passage 45 is full of by body, then it is filled with inside the buffering accumulator 41 via the first passage 4311 upwards, Carry out interim storing；If the injection structure injection and pressurize are finished, the injection gate valve 46 is in the injection gate valve oil cylinder Open under 47 drive, meanwhile, the storage is penetrated gate valve 43 and is moved to as shown in Figure 7 in the drive that gate valve oil cylinder 44 is penetrated in the storage Position, the injection melt that compounding structure conveying comes flowed in the passage 45, with this via the doubled via 4321 Meanwhile, the injection melt of buffering 41 storage inside of accumulator under the pressurization stored up and penetrate oil hydraulic cylinder 42, via the Two passages 4312 and three through holes 4322 are flowed in the passage 45.In actual production process, once cache storing and terminate, institute State injection melt to flow out from the buffering accumulator 41, but as the injection melt viscosity is larger, have described in fraction Injection melt buffers 41 internal residual of accumulator described, when the new injection melt is filled with institute from the first passage 4311 When stating buffering accumulator 41, the injection melt of residual will have part to be pressed against 4312 top of the second channel, work as caching At the end of storing, the injection melt of part residual is flowed out via second channel 4312, is so circulated, the outmoded note of residual Modeling melt will be substituted by new injection melt, is made the injection melt by turnover is exchanged in two valve roads, is reduced old material and exist It is described to store up the residence time penetrated in transformational structure.

It is that the injection melt for being compounded structure successively for coming arranges one temporarily that transformational structure is penetrated in the storage Storage space, in the industrial production, considerably increases production efficiency, it is to avoid the infringement that repeatedly starting and stopping is caused to equipment, while keeping away Exempt to cause the heating repeatedly of the injection melt waste of the energy.

Preferred embodiment of the present utility model is the foregoing is only, is merely illustrative for this utility model, and It is nonrestrictive.Those skilled in the art understanding, can be to which in the spirit and scope limited by this utility model claim Many changes are carried out, is changed, in addition it is equivalent, but fall within protection domain of the present utility model.
