Description
Technical field
The utility model relates to a kind of Jet forming machine, particularly a kind of mix oily electric mixed ejecting device of the Jet forming machine that shoots material of drive screw that is used for.
Background technology
Many automated machines regular meeting is used in combination electrical control and oil pressure control, realizes driving or fastening task performance.Present widely used plastics Jet forming machine utilizes electric and mainstream product oil hydraulic system exactly.The frame for movement of general Jet forming machine mainly can be divided into clamping die device and ejecting device two large divisions.This clamping die device has a mould that is intermittently driven die sinking and mold closing, this ejecting device then is to be used for that fusion is mixed and the preceding plastics that send storage, and this stored plastics quantitatively penetrate off and on to the mould of mold closing, with after the typing to be cooled again die sinking take out finished product.
The utility model mainly is to illustrate at this ejecting device.Just because ejecting device in the past, for the rotation that drives a screw rod with move, have plenty of and all utilize oil hydraulic system to drive, what have then is to control by electrical system purely, for this reason, below brief description difference wherein only.
As shown in Figure 1, a kind of hydraulic type ejecting device 1 in the past, comprise material pipe 12, that a hollow urceolus 11, is plugged on the front end of this urceolus 11 stretch through screw rod 13, in this material pipe 12 be fixed in inner core 14 in the rear end of this urceolus 11, one can before and after embed the power transmission shaft 17 that cover 16, that piston 15, in this inner core 14 is fixed in the rear end of this inner core 14 and is used for spacing piston 15 is hubbed on piston 15 rotationally and is connected this screw rod 13 slippingly, and one drives the motor 18 that this power transmission shaft 17 rotates.The storing oilhole 141 and one that this inner core 14 is separated by before and after the having oilhole 142 that shoots material.And having one, this piston 15 is limited in storing oilhole 141 and the plunger portion 151 of 142 of the oilholes of shooting material.
When storing, motor 18 can drive power transmission shaft 17 and rotate, and drives the rotation in material pipe 12 of this screw rod 13, mixes in order to fusion and advances the plastics of feeding pipe 12 via urceolus 11, simultaneously this molten plastic is sent to material pipe 12 front ends and stores.As shown in Figure 2, when shooting material, high-voltage oil liquid is injected this oilhole 142 that shoots material, squeeze plunger portion 151 piston 15 is moved forward, driving power transmission shaft 17, motor 18 and screw rod 13 in company with reach, and the molten plastic of borrowing screw rod 13 will be accumulated in material pipe 12 front ends is pushed ejaculation.As shown in Figure 1, after shooting material, again high-voltage oil liquid is injected this storing oilhole 141, in order to promotion plunger portion 151 piston 15 is moved backward and reset, and the member that drive is connected with it is also in company with resetting, to carry out the storing operation of next time.
From the above, hydraulic type ejecting device 1 in the past in design, come driven plunger 15 to move though have enough big motive force, to drive these screw rod 13 storings and to shoot material, but in the control that utilizes motor 18 drive screws 13 storings, but can't precisely control effectively, cause inlet amount, cause the instability of quality of finished than inaccuracy.
As for the design of (figure does not show) of, above-mentioned electric ejecting device, though on inlet amount measure control accurately, yet in the control that drive screw 13 shoots material, but can't produce enough big motive force, make the insufficient pressure that shoots material of this screw rod 13, therefore can not keep quality of finished.Certainly, in order to have the motive force of filling part, that also motor 18 can be designed is bigger, but thus, not only comparatively power consumption also takies placement space, and is textural still undesirable.
