Abstract
The invention relates to the technical field of casting, and particularly relates to a casting die for a ductile iron part. The casting die is provided with an ingate with a feeding head, wherein the cross section of the ingate is rectangular; and the cross section of the ingate is approximately the same as the cross section of the lateral face of the part to be machined in size. The casting die for the ductile iron part provided by the invention has the beneficial effects that the ingate of the casting die for the ductile iron part provided by the invention is designed to be square, and can be used for adjusting the size of the cross section of the ingate according to the size of the part, so that a workpiece is approximately and integrally connected with the feeding head, the smoothness of a feeding channel is ensured, and the casting effect is improved.
Description
Technical field
The present invention relates to casting technology field, relate in particular to a kind of cast pieces of spheroidal casting mould.
Background technology
Spheroidal graphite cast-iron is to obtain globular graphite by nodularization and inoculation, has effectively improved the mechanical performance of cast iron, has particularly improved plasticity and toughness, thereby obtains than carbon steel high intensity also.Spheroidal graphite cast-iron is 20th century a kind of high-strength cast iron materials of growing up of the fifties, and its combination property just is being based on its excellent performance close to steel, has been successfully used to cast some stressed complexity, the part that intensity, toughness, wearability are had relatively high expectations.Spheroidal graphite cast-iron developed rapidly for be only second to casting pig, use cast iron materials very widely.So-called " with iron for steel " mainly refers to spheroidal graphite cast-iron.
The spheroidal graphite cast-iron great majority are eutectic or hypereutectic composition, and its mushy freezing mode makes the foundry goods shell not resist the graphitization expansion ability, thereby the migration of casting mold generation type wall, increase the foundry goods volume, very easily produce internal shrinkage, shrinkage porosite.
In the casting process of spheroidal graphite cast-iron, the shrinkage porosite of heat energy-saving position is the problem that often faces.The way one of our employing was to use chill in the past, the 2nd, adopt feeding head.The result of use of chill is more satisfactory, but the outward appearance of foundry goods and hardness are difficult to control.And feeding head designs to such an extent that be not quite reasonable due to dark cast gate, and general cast gate cross section is rounded or oval, and casting effect is not very desirable.
Summary of the invention
The technical problem to be solved in the present invention is: unimpeded in order to ensure Feeding channel, improve casting effect, and the invention provides a kind of cast pieces of spheroidal casting mould.
The technical solution adopted for the present invention to solve the technical problems is: a kind of cast pieces of spheroidal casting mould, ingate with feeding head, the cross section of described ingate is square, and it is basically identical that the sectional area of ingate increases the cross-sectional sizes that causes with part to be processed side.
Further, particularly, the cross section of described ingate is rectangle.
The invention has the beneficial effects as follows, the present invention is the Design of Gate squarely of cast pieces of spheroidal casting mould, and adjusts the size in ingate cross section according to the size of part, and workpiece is connected substantially in feeding head, guarantee the unimpeded of Feeding channel, improve casting effect.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the optimum embodiment of the present invention.
Fig. 2 is the sectional view of ingate of the present invention.
In figure 1, ingate, 2, workpiece.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, 2, be the optimum embodiment of the present invention, have the ingate 1 of feeding head, the cross section of described ingate 1 is rectangle or square, it is basically identical that the sectional area of ingate 1 increases the cross-sectional sizes that causes with part to be processed side, and shape is coupling mutually also.
Design of Gate rectangularity or square, and adjust the size in ingate cross section according to the size of part, workpiece is connected substantially in feeding head, guarantee the unimpeded of Feeding channel.After this technology was used on producing, the qualified casting of complicated robot cast pieces of spheroidal improved 10%, and mach cutter loss reduces by 20%, has obtained good economic benefit.
Take above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to the claim scope.
Claims (2)
