Abstract
The technical solution adopted in the present invention is：Die cavity and connection die cavity and the runner in the external world inside a kind of casting die, including top case, drag box, molding sand, molding sand, are provided with the graphite rod of insertion die cavity in described die cavity.Graphite rod is set in the present invention in die cavity, not only there is rigidity due to graphite rod again with chilling action, can effectively eliminate casting thermal center, it is to avoid the situation that casting is scrapped.
Description
Technical field
The present invention relates to casting field, especially a kind of casting die.
Background technology
Casting thermal center is because casting internal ratio surrounding metal solidifies slow node or regional area, after solidification
Thermal stress is produced, causes casting deformation, crackle, opinion casting that the defects such as loose, cold shut, stomata occur,
It is the FAQs in casting technique.
The content of the invention
The technical problem to be solved in the present invention is：Casting die in the prior art is overcome to easily cause casting thermal center
Deficiency, there is provided a kind of casting die.
It is to solve above-mentioned technical problem the technical solution adopted in the present invention：A kind of casting die, including it is upper
Die cavity and connection die cavity and extraneous runner, described die cavity inside molding box, drag box, molding sand, molding sand
Inside it is provided with the graphite rod of insertion die cavity.
Preferably, described graphite rod two ends are arranged on the die joint formed between top case and drag box.
Preferably, described graphite rod one end is arranged on the connectivity part of runner and die cavity, so in liquation stream
Acted on by graphite rod when entering die cavity, can further be reduced casting thermal center.
Preferably, described graphite rod is the special-shaped stone inker with some boss, special-shaped stone inker compares table
Area is big, effectively improves chilling action.
Graphite rod is set in the present invention in die cavity, not only there is rigidity due to graphite rod but also be there is chilling action,
Casting thermal center can effectively be eliminated, it is to avoid the situation that casting is scrapped.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram,
Basic structure of the invention is only illustrated in a schematic way, therefore it only shows the composition relevant with the present invention.
Embodiment 1
As shown in figure 1, a kind of casting die, including top case 1, drag box 2, molding sand 3, in molding sand 3
The die cavity 4 and connection die cavity 4 in portion and the runner 5 in the external world, insertion die cavity 4 is provided with described die cavity 4
Graphite rod 7.The described two ends of graphite rod 7 are arranged on the die joint formed between top case 1 and drag box 2
On 6, and one end is arranged on the connectivity part of runner 5 and die cavity 4.Specifically, described graphite rod 7 is tool
There is the special-shaped stone inker of some boss.
Not only there is rigidity due to graphite rod 7 but also there is chilling action, and can effectively eliminate casting thermal center, it is to avoid
The situation that casting is scrapped.
