Abstract
The utility model relates to a low pressure injection molding machine gear pump of moulding plastics, install on the casing through self -lubricating bearing (5) its driven shaft (4), gear (3) and driven shaft (4) link firmly, permanent magnet A (1) fixed mounting be in the lateral surface of gear (3), install on the casing through planet bearing (6) and jump ring (7) driving shaft (8), the tip of driving shaft (8) install with the magnetic disc of gear (3) looks adaptation, shown permanent magnet B (2) fixed mounting is at the lateral surface of magnetic disc, the lateral surface of gear (3) with the lateral surface contact of magnetic disc is connected. The utility model discloses must cause the rotary resistance grow of gear after the gear gets into the foreign matter, when its resistance greatly to can offset because of permanent magnet and the mutual actuation of permanent magnet after during ability synchronous transmission's torsion, the idle running of driving shaft has been realized to gear and magnetic disc alternate segregation, has avoided after getting into the foreign matter gear then caused the damage by the positive drive.
Description
Technical field
The utility model relates to a kind of low-pressure injection molding machine, is specifically related to a kind of low-pressure injection molding machine injection made gear pump.
Background technique
At present, in known low-pressure injection molding machine, injecting glue gear pump is all operate in the mode direct-connected with power motor rigidity, when there being foreign matter to enter after in gear pump, motor rotation blockage will being caused to cause equipment damage or damage, cause service life reduction; Simultaneously due to the long-term running of gear pump, the cushion rubber in each sealing place will inevitably wear and tear in various degree, and the direct mode of rigidity makes gear pump occur sealing not exclusively, causes leaking glue phenomenon and occurs.
Model utility content
The purpose of this utility model is to provide a kind of low-pressure injection molding machine injection made gear pump, and solve in existing low-pressure injection molding machine, injecting glue gear pump is easily damaged by the foreign matter entered, and the problem that sealing effect can reduce day by day.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of low-pressure injection molding machine injection made gear pump, comprise permanent magnet A, permanent magnet B, gear, driven axle, self oiling bearing, planetary bearing, jump ring and driving shaft, wherein said driven axle is arranged on casing by self oiling bearing, described gear and driven axle are connected, and described permanent magnet A is fixedly mounted on the outer side surface of described gear; Described driving shaft is arranged on casing by planetary bearing and jump ring, and the end of described driving shaft is provided with the disk suitable with described gear, and shown permanent magnet B is fixedly mounted on the outer side surface of disk; The outer side surface of described gear is connected with the outer side surface contact of described disk.
Further, described casing is made up of the first casing, the second casing and the 3rd casing fastening successively by fastening screw, fixing pin, driven axle is mounted in two casings mutually fastened by self oiling bearing, described gear is mounted in the gear cavity that formed after the first casing and the second casing fasten, and described disk is arranged in dish groove that the 3rd casing is formed.
Compared with prior art, the beneficial effects of the utility model are: the utility model makes the gear of driven axle and the disk of driving shaft adopt flexible connecting transmission, the rotational resistance of gear must be caused after gear enters foreign matter to become large, when its resistance greatly to can to offset after because of permanent magnet and the mutual adhesive of permanent magnet can the torsion of Synchronous Transmission time, described gear and disk are separated from each other, achieve the idle running of driving shaft, avoid after entering foreign matter, then gear is caused damage by positive drive.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Fig. 2, Fig. 3 and Fig. 4 show an embodiment of a kind of low-pressure injection molding machine of the utility model injection made gear pump: a kind of low-pressure injection molding machine injection made gear pump, comprise permanent magnet A1, permanent magnet B2, gear 3, driven axle 4, self oiling bearing 5, planetary bearing 6, jump ring 7 and driving shaft 8, wherein said driven axle 4 is arranged on casing by self oiling bearing 5, described gear 3 and driven axle 4 are connected, and described permanent magnet A1 is fixedly mounted on the outer side surface of described gear 3; Described driving shaft 8 is arranged on casing by planetary bearing 6 and jump ring 7, and the end of described driving shaft 8 is provided with the disk suitable with described gear 3, and shown permanent magnet B2 is fixedly mounted on the outer side surface of disk; The outer side surface of described gear 3 is connected with the outer side surface contact of described disk.
According to a preferred embodiment of a kind of low-pressure injection molding machine injection made gear of the utility model pump, described casing forms by by fastening successively the first casing 11, second casing 12 of fastening screw 9, fixing pin 10 and the 3rd casing 13, driven axle 4 is mounted in two casings mutually fastened by self oiling bearing 5, described gear 3 is mounted in the first casing 11 and the second casing 12 fastens in the gear cavity of rear formation, and described disk is arranged in the dish groove of formation on the 3rd casing 13.
Working principle of the present utility model is: when the injection made gear pump of low-pressure injection molding machine normally runs, by permanent magnet A1 and the mutual adhesive of permanent magnet B2, the disk making the gear 3 of driven axle 4 and driving shaft 8 mutually near and Synchronous Transmission, sealing effect is between the two also because magnetic force remains at good sealing effect, the rotational resistance of gear 3 must be caused after gear 3 enters foreign matter to become large, when its resistance greatly to can to offset after because of permanent magnet A1 and the mutual adhesive of permanent magnet B2 can the torsion of Synchronous Transmission time, described gear 3 and disk are separated from each other, achieve the idle running of driving shaft 8, avoid after entering foreign matter, then gear 3 is caused damage by positive drive.
Although be described the utility model with reference to multiple explanatory embodiment of the present utility model here, but, should be appreciated that, those skilled in the art can design a lot of other amendment and mode of execution, these amendments and mode of execution will drop within spirit disclosed in the present application and spirit.More particularly, in the scope of, accompanying drawing open in the application and claim, multiple modification and improvement can be carried out to the constituent elements of subject combination layout and/or layout.Except the distortion carried out constituent elements and/or layout and improving, to those skilled in the art, other purposes also will be obvious.
