Abstract
The present invention relates to a special mould for casting a helicoid and a shaping method of the helicoid. A helicoid casting model of the present invention comprises two helical communities whose cross sections are semicircular and two upper core moulds whose cross sections are semicircular, wherein the diameters of the upper ends of the upper core moulds are larger than the diameters of the helical communities, and the height of the upper ends of the upper core moulds is larger than one quarter of the product of the head number of the helicoid and a helical distance. The model of the present invention overcomes the defect that a common casting process can not be used for casting the helicoid, and the model has the advantages of simple manufacture and convenient use.
Description
(1) technical field under
The present invention relates to a kind of mould of casting spirochetal special use, and spirochetal formative method.
(2) background technology
In the conventional cast technology, spirochetal moulding is very difficult, especially produces in enormous quantities, requires efficient and quality and economy to take into account, and can be described as impossible.If use advanced model casting etc., its cost is quite high.Open day is the Chinese patent of on January 15th, 1997, application number 961049626: " centrifugal casting of screw of screw oil extruder and formative technology ", adopt centrifugal casting and formative technology, conveyor screw is cast, but this method needs specialized apparatus the technology more complicated.
(3) summary of the invention
The present invention is in order to overcome the deficiency of above technology, provides a kind of and can adopt having that conventional cast technology casts to make special purpose model simple, easy to use.
Adopt the formative method of above-mentioned special purpose model to have that technology is simple, easy to operate, cost is lower, be suitable for common casting technique produces conveyor screw.
Conveyor screw casting pattern of the present invention, include two spiral communities, two cross sections are the semicircular core of going up, the upper end external diameter of last core is greater than the external diameter of spiral community, the upper end height of last core is long-pending 1/4th greater than conveyor screw head number and pitch, and the profile of spiral community is identical with half spirochetal profile behind the vertical profile.
Conveyor screw casting pattern of the present invention, in order to cast the conveyor screw of hollow cast, described spiral community is divided into conveyor screw core and semicolumn inner core two parts, is fixed as one during use.
Conveyor screw casting pattern of the present invention also includes a pressing plate that matches with the conveyor screw longitudinal section.When spiral community is taken out in rotation, can prevent that sand mold is loosening.
Conveyor screw casting pattern of the present invention, for easy to operate, the upper surface of described spiral community and last core all has the operative position of a groove shape.
Adopt the formative method of above-mentioned conveyor screw casting pattern, include following steps,
(1) carries out modeling according to conveyor screw;
(2) conveyor screw core and semicolumn inner core are fixed as spiral community, and, are positioned in the sandbox on the flat board, add sand and compacting, again sandbox is turned over turnback with after last core aligns;
(3) take out upward core earlier, pressing plate is pressed on a side of conveyor screw core again, rotating screw community takes out spiral community.
Model of the present invention has overcome employing conventional cast technology and can not cast spirochetal deficiency, and this model has to be made simply, easy to use.
Adopt the formative method of above-mentioned special purpose model to have that technology is simple, easy to operate, cost is lower, be suitable for adopting common casting technique to produce conveyor screw.
(4) description of drawings
Fig. 1 tamps modeling structure schematic diagram after sand turns over turnback for the present invention
Among the figure, 1 conveyor screw core, 2 semicolumn inner cores, core on 3,4 operative positions, 5 sandboxes, 6 pressing plates.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done concrete description.
Present embodiment is used for casting the conveyor screw of hollow cast.
Its special-purpose model by two semicolumn inner cores 2, two conveyor screw cores 1, two go up core 3, a pressing plate 6 is formed.Semicolumn inner core 2 is the semicolumn bodily form, matches with the conveyor screw inner chamber.Semicolumn inner core 2 is fixed as spiral community with conveyor screw core 1.Last core 3 is positioned at the top of spiral community, be the semicolumn bodily form, the equal diameters of the lower end diameter of last core and semicolumn inner core, the upper end diameter of last core is slightly larger than the external diameter of conveyor screw core 1, and the upper end of last core highly is slightly larger than long-pending 1/4th of conveyor screw head number and pitch.The outer surface of semicolumn inner core 2 and last core 3 respectively has the operative position 4 of a groove shape, uses when being used to take out model.The profile of pressing plate 6 and spirochetal longitudinal section match.
Casting method is: carry out modeling according to spirochetal size; Semicolumn inner core 2 and conveyor screw core 1 be fixed as one form spiral community, and, be positioned in the sandbox on the flat board, add sand and compacting then, again sandbox is turned over turnback with after last core aligns; State as shown in Figure 1.Rap model, making has suitable gap between the sand mold, takes out earlier and goes up core 3, according to spirochetal left and right revolving, determines the pressing plate placement location, lives pressing plate with a hand, and another holds the operative position 6 of semicolumn inner core, revolves to turn 90 degrees, and takes out spiral community.
Similar approach is produced second half sand mold.
With common formative method, produce the assembly sand mold of semicolumn inner core 2 and last core 3, be positioned in the above-mentioned sand mold.Then, cast.
Claims (5)
1. conveyor screw casting pattern, it is characterized in that: include two spiral communities, two cross sections are the semicircular core of going up, the upper end external diameter of last core is greater than the external diameter of spiral community, the upper end height of last core is long-pending 1/4th greater than conveyor screw head number and pitch, and the profile of spiral community is identical with half spirochetal profile behind the vertical profile.
2. conveyor screw casting pattern according to claim 1 is characterized in that: described spiral community is made up of conveyor screw core and semicolumn inner core.
