Abstract
The invention discloses a kind of straight section ceramics sprue bush, its top connection foam sprue cup (5), bottom connection sprue straight section (6), described sprue bush to include conic ceramic mother set (1), conic ceramic sub-set (2)；Described conic ceramic mother set (1) forms taper fit by the outer conical surface of internal taper hole and conic ceramic sub-set (2).Using above-mentioned technical proposal, production cost is reduced：Conic ceramic covers and 0.93 yuan of straight section master-slave casing prices/set, according to averagely being calculated daily using 60, can save 20,000 yuan every year；Cancellation uses joint sealing mud bar, annual to save 5000 yuan；Improve product quality：Product defects is reduced, is solved because collecting knurl substandard products caused by ceramic jacket reason.
Description
Technical field
The invention belongs to the technical field of cast iron pipe production technology equipment.A kind of more particularly it relates to straight section pottery
Porcelain sprue bush.
Background technology
Because of lost foam process and the characteristic of evaporative pattern production equipment, timely yield is produced to improve evaporative pattern, accelerates production
Rhythm, improve production efficiency, production line moulding station increase overlay film station.To ensure product quality and efficiency, in prior art
In, docked using straight section primary and secondary ceramics sprue bush, be flat seal during because of docking, it is necessary to using joint sealing mud bar by mating surface
Sealing, prevents iron night from overflowing.
Above-mentioned prior art has the drawback that：
1st, straight section primary and secondary ceramic jacket mating surface coordinates for the plane of end face, requires height, it is necessary to use joint sealing product end surface
Mud bar carries out auxiliary seal；
2nd, during the use of straight section primary and secondary ceramic jacket, factor mother gap fit dimension is big, easily produce skew and it is crooked, no
It can well seal, casting collection knurl often occur.Moulding castings sprue collection knurl, directly results in casting sand washing, influences casting
Inherent quality.
The content of the invention
The present invention provides a kind of straight section ceramics sprue bush, the purpose is to reduce the production cost of sprue bush, improves interface
Quality of connection.
To achieve these goals, the technical scheme taken of the present invention is：
The straight section ceramics sprue bush of the present invention, its top connection foam sprue cup, bottom connection sprue straight section are described
Sprue bush includes conic ceramic mother set, conic ceramic sub-set；Described conic ceramic mother set passes through internal taper hole and conic ceramic
The outer conical surface of set forms taper fit.
The diameter in the internal taper hole aperture of described conic ceramic mother set is more than internal diameter.
Between described conic ceramic mother set, the opposing end surface of conic ceramic sub-set, end clearance is formed.
The top docking foam sprue cup of described conic ceramic mother set；The bottom docking sprue of conic ceramic sub-set is straight
Section.
The present invention uses above-mentioned technical proposal, reduces production cost：Conic ceramic covers and straight section master-slave casing prices
0.93 yuan/set, according to averagely being calculated daily using 60,20,000 yuan can be saved every year；Cancellation uses joint sealing mud bar, annual to save
5000 yuan；Improve product quality：Product defects is reduced, is solved because collecting knurl substandard products caused by ceramic jacket reason.
Brief description of the drawings
Content shown in accompanying drawing and the mark in figure are briefly described as follows：
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the schematic diagram of the conic ceramic sprue bush partial structurtes amplification in Fig. 1.
In figure mark for：
1st, conic ceramic mother set, 2, conic ceramic sub-set, 3, taper sheath mating surface, 4, end clearance, 5, foam sprue cup,
6th, sprue straight section.
Embodiment
Below against accompanying drawing, by the description to embodiment, embodiment of the invention is made further details of
Illustrate, to help those skilled in the art to have more complete, accurate and deep reason to inventive concept of the invention, technical scheme
Solution.
Expressed structure of the invention as shown in Figure 1, Figure 2, is a kind of straight section ceramics sprue bush, and its top connects foam cast gate
Cup 5, bottom connection sprue straight section 6.As shown in figure 1, the top docking foam sprue cup 5 of 2, conic ceramic mother set 1, taper pottery
The bottom docking sprue straight section 6 of porcelain sub-set 2.
The defects of in order to overcome prior art, the production cost for reducing sprue bush is realized, improves the quality of connection of interface
Goal of the invention, the technical scheme that the present invention takes are：
As shown in Figure 1 and Figure 2, straight section ceramics sprue bush of the invention, described sprue bush include conic ceramic mother set 1, cone
Shape ceramics sub-set 2；Described conic ceramic mother set 1 forms taper by the outer conical surface of internal taper hole and conic ceramic sub-set 2 and matched somebody with somebody
Close, that is, form the taper sheath mating surface 3 in Fig. 1 and Fig. 2.
The present invention uses conic ceramic interface set, straight section primary and secondary ceramics nested structure is redesigned, by original end
Face, which coordinates, is changed to cone match, increases the area of mating surface, solves, because of the crooked and offset problem of straight section primary and secondary ceramic jacket, to improve
The quality of docking；Using conic ceramic mother set 1 and the cone match of conic ceramic sub-set 2, fit clearance is eliminated, reaches required
Seal request.Simultaneously as conic ceramic set can cancel the use of mud bar, supplementary material cost is saved.
The diameter in the internal taper hole aperture of described conic ceramic mother set 1 is more than internal diameter.
Between described conic ceramic mother set 1, the opposing end surface of conic ceramic sub-set 2, end clearance 4 is formed.
As shown in figure 1, straight section primary and secondary ceramic jacket includes conic ceramic mother set 1, conic ceramic sub-set 2；Conic ceramic mother set
1st, conic ceramic sub-set 2 forms taper sheath mating surface 3；Conic ceramic mother set 1, conic ceramic sub-set 2 opposing end surface between, shape
Into end clearance 4.So that after coordinating surface wear, it can only reduce the gap value of end clearance 4, without making because of end in contact
Taper fit produces gap.
The top docking foam sprue cup 5 of described conic ceramic mother set 1；The bottom docking of conic ceramic sub-set 2 is directly poured
Road straight section 6.
It is of the invention to be using the beneficial effect of above-mentioned technical proposal：
Reduce cost：Conic ceramic covers and 0.93 yuan of straight section master-slave casing prices/set, and 60 are used according to averagely daily
Calculate, 20,000 yuan can be saved every year；Cancellation uses joint sealing mud bar, annual to save 5000 yuan；Improve product quality：Product is reduced to lack
Fall into, solve because collecting knurl substandard products caused by ceramic jacket reason.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that present invention specific implementation is not by aforesaid way
Limitation, as long as the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is employed, or without changing
Enter and the design of the present invention and technical scheme are directly applied into other occasions, within protection scope of the present invention.
