Abstract
The utility model provides a cold core of a wax mold. The cold core of the wax mold is in shape of horn outside, and hollow inside, with a wax injection channel provided at the hollow portion. A channel is provided inside the cold core of the structure, and wax liquid can flow therefrom, so that the problem of bottom wax injection is solved. The wax liquid can not only enclose the cold core from outside, but also pass through the channel of the cold core. As a result, the wax injection time is shortened. The cold core with channel has an external form close to the hub of the wax mold, so thatcontraction rate of the wax mold is effectively controlled, pressure keeping time is shortened, and working efficiency is improved.
Description
Technical field
The utility model relates to a kind of wax-pattern cold core, particularly a kind of wax-pattern cold core that can reduce wax-pattern contraction distortion rate.
Background technology
Traditional cold core is solid, for casting certain influence is arranged, can not take from the mode of bottom casting, because cold core has been blocked the runner of casting, in the casting process, wax from around remove to wrap up cold core, can occur wax liquid like this and also not fill with the phenomenon that the die cavity of mould just solidifies, can cause the out-of-flatness on wax-pattern surface like this, and the dwell time can be long, influences production efficiency.
The utility model content
The technical problems to be solved in the utility model provides a kind of wax-pattern cold core that can reduce wax-pattern contraction distortion rate.
For solving the problems of the technologies described above, a kind of wax-pattern cold core of the present utility model, described wax-pattern cold core is tubaeform, its innovative point is: described wax-pattern cold core is inner for hollow, is provided with the casting runner in its hollow part.
The advantage of above structure is: have runner in the described cold core, wax liquid can flow out in runner.Solved the problem of mold bottom casting; Wax liquid not only can also pass through from the runner of cold core from cold core outer wrap cold core, has shortened the casting time; The cold core of described band runner is more near the profile of wax-pattern wheel hub, thereby the shrinkage factor of more effective control wax-pattern has reduced dwell time of wax-pattern simultaneously, has improved operating efficiency.
Description of drawings
Be illustrated as structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
As shown in the figure, described cold core 1 is by the mold integral injection mo(u)lding, and being shaped as of cold core 1 is horn-like, is hollow shape, has wax liquid runner 2 at its hollow parts.
During work, wax liquid is by outer wrap cold core 1, and part wax liquid flows into the wax liquid runner 2 of cold core 1 from the bottom, shortened the casting time, and cold core 1 profile of described band wax liquid runner 2 more approaches the wax-pattern wheel hub, thus the shrinkage factor of more effective control wax-pattern.
