Abstract

The utility model belongs to the casting technical equipment and particularly relates to a self-hardening sand core bar cylinder which comprises a sand mould (1) and a sand core (3), wherein a core bar cylinder (4) is arranged in the middle of the sand core (3); a plurality of air outlets (4-1) are uniformly distributed on the wall of the core bar cylinder (4); the sand mould (1) is arranged on the periphery of the sand core (3); and a cavity (2) is arranged between the sand mould (1) and the sand core (3). The self-hardening sand core bar cylinder has a function of a core bar; the strength of the sand core is greatly increased; the sand dosage is saved; the use effect is more obvious in the cast production of large-size pipe cylinders; air outlets are uniformly drilled on the wall of the core bar cylinder, so that the excellent air-permeability of the sand core is ensured; the effect of reducing the defect of pin holes and air holes on a cast piece is obvious; a core head can be directly replaced by the core bar cylinder; the precision, the consistency and the matching effect can be more easily ensured; and the size precision of the cast piece is greatly increased.

Description

Self-hardening sand arbor tube
Technical field
The utility model belongs to casting technique equipment, particularly a kind of self-hardening sand arbor tube.
Background technology
In the self-hardening sand molding process, core is generally solid integral body, in bury reinforcing bar and do arbor; Both caused the waste of core sand and resin material; Handle for again knockout and sand and form difficulty and workload, it is unfavorable especially mould permeability to be improved, and foundry goods pin hole core defective tendency is bigger.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned technical deficiency, provides a kind of can the minimizing to use sand, can improve the self-hardening sand arbor tube of cored density.
The technical scheme that the utility model technical solution problem adopts is: self-hardening sand arbor tube comprises sand mold, core; Be characterized in being provided with an arbor tube in the centre of core; Be laid with several ventholes on the arbor tube barrel, the periphery of core is provided with sand mold, is provided with die cavity between sand mold and the core.
The beneficial effect of the utility model is: self-hardening sand arbor tube had both played the effect of arbor, strengthened sand core strength greatly, can practice thrift sand using amount again; Especially result of use is more obvious in large-scale socket class castings production, and arbor tube barrel is evenly got pore, can guarantee the core air permeability and good; To reducing foundry goods pin hole core defective positive effect is arranged; The arbor tube can directly replace core print, and its precision, uniformity, fiting effect are easier to guarantee, casting dimension accuracy is significantly improved.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is a self-hardening sand arbor barrel structure cutaway view.
Among the figure, the 1-sand mold; The 2-die cavity; The 3-core; 4-arbor tube; The 4-1-venthole.
The specific embodiment
Embodiment, with reference to accompanying drawing 1, self-hardening sand arbor tube is to be provided with an arbor tube 4 in the centre of core 3, is laid with several ventholes 4-1 on the barrel of arbor tube 4, the periphery of core 3 is provided with sand mold 1, establishes die cavity 2 between sand mold 1 and the core 3.Self-hardening sand arbor tube is applicable to the production of large-scale socket class foundry goods, and its saving and mass effect are particularly outstanding.
