Abstract
The invention relates to a precoated sand casting mold. The precoated sand casting mold comprises a base body, an upper mold body and a lower mold body, and is characterized in that the left side and the right side of the base body are respectively provided with a baffle plate, the lower mold body is fixed on one baffle plate, sliding rods which are disposed on the upper part and the lower part of the lower mold body are arranged between the two baffle plates, the upper mold body is fixed on the two sliding rods in a rotating manner, and the upper mold body is also connected with an air cylinder; two ends of the upper mold body and the lower mold body are respectively symmetrically provided with two rotating shafts, and the axes of the two rotating shafts stay on a same axis. The precoated sand casting mold is convenient to move and efficient to use.
Description
Technical field
The present invention relates to a kind of casting mould, particularly relate to a kind of precoated sand casting mould.
Background technology
The technique of precoated sand coremaking is precoated sand kneading completed, blow to the metal die cavity being warmed to 250-280 DEG C with pressure, pass through conduction of heat, phenolic resin is made to soften, melted, then solidify, shelly is formed in now sand mold hardening, therefore its another name is also known as shell sand moulding, the shortcoming of precoated sand coremaking is to use the metal die heated, precoated sand mould itself has the biggest weight, artificial movement is inconvenient for, secondly, during use, need with combustion gas, mold exterior to be heated, after mould is heated, the most more it is difficult to it is implemented the operations such as carrying and shelling owing to temperature is the highest.
Precoated sand i.e. sand grain surface is i.e. covered with molding sand or the core sand of one layer of hard resin film before moulding.Having cold process and two kinds of coating techniques of Re Fa: resin is dissolved by cold process ethanol, and add hexamethylenamine during mulling, make the two be coated on sand grain surface, ethanol volatilizees, and obtains precoated sand；Full-boiled process is preheating to uniform temperature sand, adds resin and makes it melt, and stirring makes resin-coating at sand grain surface, adds hexamethylenamine aqueous solution and lubricant, cools down, crushes, sieves to obtain precoated sand, for steel-casting, ironcasting.Precoated sand foundary weight mould is the mould used in foundary weight manufacturing and having precoated sand.This kind of mould needs special, manufacture process to be completed by Mechanical course, and prior art is not suitable for.
Summary of the invention
Not enough for prior art, the invention provides a kind of precoated sand casting mould being moved easily.
The present invention solves the technical scheme of above-mentioned technical problem employing: a kind of precoated sand casting mould, include matrix, upper die body, lower mold body, the arranged on left and right sides of matrix is respectively equipped with one piece of baffle plate, described lower mold body is fixed therein on one piece of baffle plate, the upper and lower part being positioned at lower mold body between two described baffle plates is provided with a slide bar respectively, upper die body rotates and is fixed on two slide bars, described upper die body is also associated with cylinder: the two ends of described upper die body and lower mold body are symmetrically arranged with two rotating shafts, and the axle center of described two rotating shafts is on same axial line.
Further, described two rotating shafts being each provided with an inward turning body, the inward turning body size in described two rotating shafts is identical.
Further, the fixed form that described lower mold body is fixed therein on a baffle plate is welding or screw fastened.
Further, described upper die body and lower mold body mutually fasten, and are internally formed core die cavity, described upper die body and lower mold body outer surface and are set side by side with a plurality of fin.
Further, described fin is wavy.
In use, lower mold body is fixed, and upper die body has cylinder control so that it is reciprocatingly slided on slide bar by inward turning body；Or upper die body is fixed, lower mold body has cylinder control so that it is reciprocatingly slided on slide bar by inward turning body.
Compared with prior art, the beneficial effect that the present invention possesses:
Present configuration is simple, easy to use, and lower mold is fixed, and upper mold has cylinder control so that it is reciprocatingly slide on slide bar, and whole process is by mechanical braking, and staff need not touch mould；The precoated sand mould of the present invention, by arranging two identical inward turning bodies of size in die ontology lateral symmetry, make precoated sand mould can move in orbit and overturn, from regardless of whether mold temperature is how high, all can move moulds easily, not only reduce the labor intensity of workman, also improve work efficiency simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
The present invention is described further below in conjunction with the accompanying drawings.
A kind of precoated sand casting mould as shown in Figure 1, include matrix 1, upper die body 2, lower mold body 3, the arranged on left and right sides of matrix 1 is respectively equipped with one piece of baffle plate 4, described lower mold body 3 is fixed therein on one piece of baffle plate 4, the upper and lower part being positioned at lower mold body 3 between two described baffle plates 4 is provided with a slide bar 5 respectively, upper die body 2 rotates and is fixed on two slide bars 5, described upper die body 2 is also associated with gas 6 cylinder: the two ends of described upper die body 2 and lower mold body 3 are symmetrically arranged with two rotating shafts, and the axle center of described two rotating shafts is on same axial line.
Further, described two rotating shafts being each provided with an inward turning body, the inward turning body size in described two rotating shafts is identical.
Further, the fixed form that described lower mold body 3 is fixed therein on a baffle plate 4 is welding or screw fastened.
Further, described upper die body and lower mold body mutually fasten, and are internally formed core die cavity, described upper die body and lower mold body outer surface and are set side by side with a plurality of fin.
Further, described fin is wavy.
In use, lower mold body 3 is fixed, and upper die body 2 has cylinder 6 to control so that it is reciprocatingly slided on slide bar 5 by inward turning body；Or upper die body 3 is fixed, and lower mold body 2 has cylinder 6 to control so that it is reciprocatingly slided on slide bar 6 by inward turning body.
