Abstract
The utility model discloses a grinding disc type screw rod for an injection molding machine with a micro-fine injection molding function. The grinding disc type screw rod comprises a grinding disc screw rod and a grinding disc, wherein the grinding disc screw rod is provided with a grinding disc screw rod groove; the grinding disc is provided with a grinding disc groove. Compared with an elongated rod-like screw rod, the grinding disc type screw rod has the advantages of high strength, high rigidity and easiness in manufacturing, maintenance and cleaning; in addition, a discharging hole can be enlarged, normal raw plastic materials can be directly processed, and the problem of sol for injection molding or extrusion of a small amount of plastic is solved. The cost is controlled, the mold price is reduced, and the effect of zero waste materials can be achieved due to no stub bars.
Description
Technical field
The utility model relates to plastic screw field, relates in particular to a kind of abrasive disk type screw rod.
Background technology
Along with arriving micro-, nanometer era, product microminiaturization, equipment microminiaturization will be following trend, even, also more and more higher for the precision of small product and the requirement of complexity, the use of plastic material is also more and more diversified, obviously, for the application of precise and tiny injection molding, traditional jet injection moulding machine has been no longer a kind of economically feasible solution.If today we to want that a mouselet is become to an elephant so large, common practices amplifies size and present linearizing increase exactly, thinks it over, will how this big rat be a situation? can't stand, can't walk any longer; Because body weight be of a size of cube relation, and the sectional area that bears weight be of a size of quadratic relationship.As a same reason, an elephant is become to a mouse the same when size, allow large injection machine become small injection machine, whether will produce the problem of much efficiency and shaping.
Emission forming machine is on the market mostly to assemble very large equipment over the years; when the little article of shaping volume production; can be often to use large injection machine to go the volume production that is shaped; although the manufacturer of injection machine has developed small shaping machine always; the screw rod of general injection machine is long clavate; there is spiral goove its side, the degree that also only makes former injection machine dwindle 10%-20% in any case, the in other words scaled down version of just individual injection machine.Therefore, in the urgent need to developing new-type screw-rod structure.
Utility model content
Large in order to overcome the emission forming machine volume of precise and tiny injection molding in prior art, the defect of consumption of raw material and waste resource, the purpose of this utility model is to provide a kind of abrasive disk type screw rod.
The purpose of this utility model is achieved by the following technical programs:
An abrasive disk type screw rod, for the emission forming machine of precise and tiny injection molding, comprises mill screw rod and mill, and described mill screw rod is provided with mill screw slot, and described mill is provided with mill groove.Described abrasive disk type screw rod is discoid.
Further, described mill screw slot in the shape of a spiral.The inside and outside weekly assembly of mill screw slot obtains mixing effect because speed is different.
Described mill trench bottom is provided with centre bore, is wound with centre bore and is circle type and has a plurality of sickle shaped through holes.Preferably, described sickle shaped through hole has 6.During processing plastic grain raw material, plastic pellet raw material mixes outflow by centre bore and sickle shaped through hole.
The utility model is applied to the emission forming machine of precise and tiny injection molding, and the feed opening of described abrasive disk type screw rod can be manufactured greatlyr, can directly process normal plastic pellet raw material, reduces Mould Machining, and can be because reach the effect of zero waste material without stub bar.
Compared with prior art, the beneficial effects of the utility model are as follows:
With the comparison of long clavate screw rod, the utlity model has high strength, high rigidity, easily manufacture, easy-maintaining, easy to clean, feed opening can be manufactured greatlyr in addition, can directly process normal plastic raw materials, solves the injection moulding of pettiness amount plastics or the colloidal sol problem of extruding.Except the reduction Die price of controlling cost, and can be because reach the effect of zero waste material without stub bar.

Fig. 1 is mill screw-rod structure schematic diagram of the present utility model; Wherein, 1, mill screw slot;
Fig. 2 is mill screw rod stereogram of the present utility model; Wherein, 2, mill screw rod;
Fig. 3 is mill structural representation of the present utility model; Wherein, 3, mill groove; 5, sickle shaped through hole; 6, centre bore;
Fig. 4 is mill stereogram of the present utility model; Wherein, 4, mill.
The specific embodiment
Below in conjunction with specific embodiment, the present invention is made further and being elaborated, but embodiment does not limit in any form the present invention.
Embodiment 1
As shown in Fig. 1,2,3 and 4, a kind of abrasive disk type screw rod, comprises mill screw rod 2 and mill 4, and mill screw slot 1 is arranged on mill screw rod 2, and mill groove 2 is arranged on mill 4.The spiral goove of the side of this screw rod and traditional long clavate screw rod is different, and this abrasive disk type screw rod is discoid.In the shape of a spiral, its inside and outside weekly assembly obtains mixing effect to mill screw slot 1 because speed is different.Described mill groove 3 bottoms are provided with centre bore 6, are wound with centre bore 6 and are circle type and open 6 sickle shaped through holes 5.Abrasive disk type screw rod and the comparison of long clavate screw rod, there is high strength, high rigidity, easily manufacture, easy-maintaining, easy to clean, feed opening can be manufactured greatlyr in addition, can directly process normal plastic raw materials, solves the injection moulding of pettiness amount plastics or the colloidal sol problem of extruding.Except the reduction Die price of controlling cost, and can be because reach the effect of zero waste material without stub bar.
Claims (3)
