Abstract
The invention relates to an erosion-preventing casting mold core. The erosion-preventing casting mold core comprises a mold core body, and a cavity is formed in the mold core body; the cavity is connected with an injection flow way and an output flow way; a centre hole is formed inside the cavity; the centre hole right corresponds to the liquid flow-in direction of the injection flow way; a centre hole protection sleeve is further arranged on the centre hole; and according to the erosion-preventing casting mold core, after the centre hole protection sleeve is added on the position of the centre hole, the centre hole can be effectively protected against erosion, after the centre hole protection sleeve is used for a long time, the sleeve is eroded, the centre hole protection sleeve can be instantly replaced, the replacement cost is low, replacement can be carried out at any time, operation is convenient, and the problem that due to erosion of a casting product, the quality is reduced is solved.
Description
Technical field
The present invention relates to cast core rod field, particularly relate to the casting core rod of a kind of fluid erosion prevention.
Background technology
For casting core rod, owing to metal liquid is when injection runner is injected into die cavity, can be right
Centre hole in die cavity directly impacts, after using the long period, and the easy erosion of centre hole, thus cause casting
Product quality decline.
Summary of the invention
For solving above-mentioned technical problem, the invention provides the casting core rod of a kind of fluid erosion prevention.
The technical solution adopted for the present invention to solve the technical problems is: the casting core rod of a kind of fluid erosion prevention, it
Including core rod body, described core rod is the most internal is provided with die cavity；Described die cavity connects injection runner and output
Runner；Described die cavity is internally provided with centre hole；The just corresponding liquid inflow side injecting runner of described centre hole
To；Centre hole protection set it is additionally provided with on described centre hole.
Beneficial effects of the present invention: the casting core rod of a kind of fluid erosion prevention of the present invention, adds in the position of centre hole
After upper centre hole protection set, can be effectively protected centre hole not by erosion, it is longer that centre hole protection is enclosed within use
By erosion after time, can change centre hole protection set immediately, replacement cost is cheap, changes at any time, behaviour
Facilitate, it is to avoid the problem of the Quality Down that cast article occurs because of erosion.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the casting core rod of a kind of fluid erosion prevention of embodiment；
Fig. 2 is the schematic diagram of the centre hole protection set of the casting core rod of a kind of fluid erosion prevention of embodiment.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples, the present invention is done the most in detail
Thin description, this embodiment is only used for explaining the present invention, constitutes protection scope of the present invention and limit.
Embodiment
As depicted in figs. 1 and 2, the casting core rod of a kind of fluid erosion prevention, it includes core rod body 1, described core rod
Die cavity 2 it is provided with in body 1；Described die cavity 2 connects injection runner 3 and delivery channel 4；Described die cavity
2 are internally provided with centre hole 5；The positive corresponding liquid inflow direction injecting runner 3 of described centre hole 5；Described
Centre hole protection set 6 it is additionally provided with on centre hole 5.
A kind of casting core rod of the fluid erosion prevention of the present embodiment, after the position of centre hole is plus centre hole protection set,
Centre hole can be effectively protected not by erosion, centre hole protection set after a longer time of use and by erosion,
Can change centre hole protection set immediately, replacement cost is cheap, changes at any time, easy to operate, it is to avoid casting is produced
The problem of the Quality Down that product occur because of erosion.
Above-described embodiment should not in any way limit the present invention, all employing equivalents or the side of equivalency transform
The technical scheme that formula obtains all falls within protection scope of the present invention.
