Description
Technical field
The present invention relates to injection machine field, especially a kind of miniature electric injection machine.
Background technology
Along with the progress of science and technology, the application of miniature injection machine will be more and more extensive.Miniaturization is various product important development direction from now on, and the market demand in fields such as electronics, information, electrical equipment, medical treatment, biologies has occurred obvious growth momentum at present.
1, the particular/special requirement of Micro Injection Molding Machines: at the beginning of the development of micro injection molding technology, do not have special injection molding machine for miniature parts manufacture.Produce in reality, generally use traditional in, large-scale injection machine coordinate multi-cavity mold design to realize part and prepare, this not only Runner Balance to mould design and require the highest, and the molding quality of part is also difficult to control to.Therefore, special injection (mo(u)lding) machine is needed to adapt to part miniaturization and high-precision requirement, compared with conventional injection molding technology, micro injection molding technology has many particular/special requirements to production equipment, mainly show as the following aspects: (1) high injection rate: micro injection molding part quality, volume are small, injection process requires to complete at short notice, to prevent melt solidification from causing part to be shorted, therefore requires during molding that injection speed is high.The injection speed of traditional hydraulic drive type injection (mo(u)lding) machine is 200mm/s, the injection speed of electrical servo motro drivien injection (mo(u)lding) machine is 600mm/s, and micro injection molding technique usually requires that the injection speed of polymer melt reaches more than 800mm/s, utilize the shear shinning principle of polymer melt, the viscosity of melt is reduced so that it is filling minute yardstick die cavity smoothly with high injection speed.(2) precise injection gauge amount: the quality of micro injection molding part is only measured with milligram, therefore Micro Injection Molding Machines needs to possess the control unit of a shot in delicate metering injection process, its quality control required precision reaches milligram level, screw stroke precision micron order to be reached.And conventional injection molding machine generally uses linear reciprocation segment injection structure, injection controlled quentity controlled variable error is relatively large, it is impossible to the trace meeting micro injection molding controls requirement, and the impact on forming parts quality is bigger.(3) quick-reaction capability: during micro injection molding, injection volume is the most small, the shift motion of the screw rod/plunger of corresponding injection device is the most small, therefore it is required that the driver element of Micro Injection Molding Machines must possess quickish response speed, thus ensure that equipment can reach required injection pressure in moment.
2, the feature of existing Micro Injection Molding Machines: for conventional injection molding machine application limitation in micro injection molding field, entering the nineties in 20th century, some companies of Europe, Japan and the U.S. have developed all types of special Micro Injection Molding Machines (usual clamp force ＜ 15t) cooperatively with scientific research institution.At present, at the whole dependence on import of China's miniature injection machine (domestic blank).External special miniature injection machine is primarily present following characteristics (not enough): (1) does not has generalization standardization: maximum injection amount is fixed, do not adapt to the different microminiaturized product demand to injection amount, need to purchase multiple stage machine and could meet the different microminiaturized product demand to injection amount, equipment component is caused to leave unused, making enterprise bear bigger cost pressure, promotion efficiency is big.(2) board is expensive: the special miniature injection machine price general charged of import one is more than 600,000 yuan.Due to all aobvious complexity of special miniature injection machine, adapted to injection system and clamping system, research and development and manufacturing cost are the highest.(3) injecting systems device assembly standardization: import injection machine is not carried out injecting systems device assembly standardization, thus, it is impossible to platform will be penetrated and take off, be contained in the injection demand realizing double-colored product or multi-colored product on other injection machines, at present, the special polychrome hydraulic injection molding machine of costliness is all used.(3) board is fixed: import miniature injection machine can not move freely, if needing mobile, it is necessary to use lifting device, move to working shop of enterprise planning management or board and make troubles, it is difficult to realize the demand of automated production.(4) using thimble to control special mechanism, action is complicated, adds cost.(5) process prompting and warning: import miniature injection machine acousto-optic buzzing is reported to the police.
