Abstract
This utility model relate to the casting core rod of a kind of fluid erosion prevention.A kind of casting core rod of fluid erosion prevention, it includes core rod body, described core rod this most internal is provided with die cavity；Described die cavity connects injection runner and delivery channel；Described die cavity is internally provided with centre hole；The just corresponding liquid inflow direction injecting runner of described centre hole；Centre hole protection set it is additionally provided with on described centre hole.The casting core rod of a kind of fluid erosion prevention of the present utility model; 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 is 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 the problem of the Quality Down that cast article occurs because of erosion.
Description
Technical field
This utility model relates to casting core rod field, particularly relates 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 in die cavity
Centre hole directly impacts, after using the long period, and the easy erosion of centre hole, thus cause the product quality of casting to decline.
Utility model content
For solving above-mentioned technical problem, this utility model provides the casting core rod of a kind of fluid erosion prevention.
This utility model solves its technical problem and be the technical scheme is that the casting core rod of a kind of fluid erosion prevention, its bag
Including core rod body, described core rod is the most internal is provided with die cavity；Described die cavity connects injection runner and delivery channel；Described die cavity
It is internally provided with centre hole；The just corresponding liquid inflow direction injecting runner of described centre hole；It is additionally provided with on described centre hole
Centre hole protection set.
The beneficial effects of the utility model: the casting core rod of a kind of fluid erosion prevention of the present utility model, in the position of centre hole
After 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 immediately centre hole protection set, replacement cost is cheap, changes at any time, easy to operate, it is to avoid cast article because of
Erosion and the problem of Quality Down that occurs.
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 understanding of the present utility model, below in conjunction with drawings and Examples, this utility model is done further
Describing in detail, this embodiment is only used for explaining this utility model, does not constitute protection domain of the present utility model and limits.
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, sets in described core rod body 1
It is equipped with die cavity 2；Described die cavity 2 connects injection runner 3 and delivery channel 4；Described die cavity 2 is internally provided with centre hole 5；Described
The positive corresponding liquid inflow direction injecting runner 3 of centre hole 5；Centre hole protection set 6 it is additionally provided with on described centre hole 5.
The casting core rod of a kind of fluid erosion prevention of the present embodiment, after the position of centre hole is plus centre hole protection set, can have
The protection centre hole of effect is not by erosion, and centre hole protection is overlapped after a longer time of use and by erosion, can be changed thimble immediately
Hole protection set, replacement cost is cheap, changes at any time, easy to operate, it is to avoid the Quality Down that cast article occurs because of erosion
Problem.
Above-described embodiment should not in any way limit this utility model, all employing equivalents or the mode of equivalency transform
The technical scheme obtained all falls within protection domain of the present utility model.
