Description
Technical field
The utility model is related to juice extractor field, especially a kind of complex and spiral propeller for juice extractor.
Background technology
As the spiral propeller of Domestic fruit extractor core component, it is generally formed by plastic injection, and outer surface is provided with
The screw body of convex tendon completes charging, squeezing food materials and the deslagging work of juice extractor in rotary work.
But when squeezing food materials, the working surface of screw body can by food materials intense attrition and squeezing action, especially
It is that lower semisection is particularly evident, therefore the spiral propeller of plastic production usually loses because of surface abrasion or convex tendon generation fracture
Effect, so that Domestic fruit extractor loses the ability squeezed the juice and scrapped completely or partly, reduces the service life of juice extractor.
The content of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of complex and spiral for juice extractor and promoted
Device.
The utility model solves the technical scheme that its technical problem used：
A kind of complex and spiral propeller for juice extractor, including central shaft and outer surface are provided with the screw rod master of convex tendon
Body, the screw body includes the lower mold insert that upper main body and wear-resistant material are made；The lower mold insert is annular hard shell, and its is embedding
Together in the upper main body bottom；There is an opening cavity volume spiral propeller bottom, the wall of the opening cavity volume by the upper main body and
Lower mold insert is collectively formed, and outer embryo is injection molded with the cavity volume the upper main body and lower mold insert are connected.
The upper main body includes upper shell and interior embryo；It is injection molded with the central shaft on the interior embryo, the interior embryo
It is injection molded with the upper shell.
The lower mold insert inwall is embedded in the fixation that the lower mold insert is realized in the groove of the outer embryo provided with convex hook.
The upper bottom part body end face is provided with caulking groove I；The lower mold insert be correspondingly provided with the caulking groove I be fitted and fixed with it is embedding
Bar I realizes axially position.
The upper main body bottom projection has the ring wall coordinated with the lower mold insert inwall；The ring wall outer wall is provided with vertical cloth
The caulking groove II put；The lower mold insert inwall is correspondingly provided with realizes radial positioning with the caulking groove II filler rod II being fitted and fixed with.
The interior embryo surface is provided with depression or raised location division.
The beneficial effects of the utility model are：It is according to the job requirement of spiral propeller different parts, stress is larger, easy
The lower semisection of abrasion decouples out, processes to form lower mold insert using harder, wear-resisting material, and stress it is small, it is nonabradable on
Main body still uses common material, so as to reduce the abrasion or damage of screw body, has both extended the service life of product, reduces again
Production cost, and the structure design of outer embryo ensure that the fastening of main body and lower insert structure, reliability is high, designs more adduction
Reason, is widely portable on various juice extractors.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is sectional view of the present utility model；
Fig. 2 is structural representation of the present utility model.
Embodiment
Reference picture 1, Fig. 2, a kind of complex and spiral propeller for juice extractor, including central shaft 1 and outer surface are provided with
The screw body of convex tendon, the screw body is divided into main body 2 and the lower mold insert 3 being made of wear-resistant material, so as to reduce
The abrasion or damage of spiral propeller, had both extended the service life of product, production cost had been reduced again；The lower mold insert 3 is
Annular hard shell, it is embedded in the bottom of upper main body 2；Spiral propeller bottom forms opening cavity volume, due to constituting opening
The wall of cavity volume is collectively formed by both, in the cavity volume the outer embryo 4 of injection can simultaneously upper main body 2 described in Adherents junction and under
Mold insert 3, makes both fastening structures and can not depart from, reasonable in design, and reliability is high.
The inwall of lower mold insert 3 is provided with convex hook 33；After injection moulding, the convex hook 33 can be embedded in the corresponding shape of outer embryo 4
Into groove, both connect and fix the axial restraint for realizing the lower mold insert 3.
The bottom end face of upper main body 2 is provided with caulking groove I21；The lower mold insert 3 is correspondingly provided with chimeric with the caulking groove I 21
Fixed filler rod I 31, build-in can directly position when lower mold insert 3 is assembled with upper main body 2, realize both axially positions.
The bottom projection of upper main body 2 has the ring wall coordinated with the lower inwall of mold insert 3；The ring wall outer wall is provided with vertical
The caulking groove II 22 of arrangement；The inwall of lower mold insert 3 is correspondingly provided with the filler rod II 32 being fitted and fixed with the caulking groove II 22；Under
Mold insert 3 can be directly chimeric when being assembled with upper main body 2 and can not rotated, and realizes both radial positionings.
Further, for the ease of processing, the upper main body 2 is divided into upper shell 5 and interior embryo 6；On the central shaft 1
It is injection molded with being injection molded with the upper shell 5 on the interior embryo 6, the interior embryo 6.
The surface of interior embryo 6 can be filled to described provided with depression or raised location division 61, the upper shell 5 of injection moulding
Location division 61, it is to avoid both depend on effect it is not good when occur axially opposing rotation.
After the technical solution of the utility model, according to the job requirement of spiral propeller different parts, by stress compared with
Greatly, lower semisection easy to wear decouples out, processes to form lower mold insert 3 using harder, wear-resisting material, and stress is small, be difficult mill
