Reusable economical insulation sink head device with efficient feeding function

The embodiment of the invention provides a reusable economical insulation sink head device with an efficient feeding function. The device comprises a sink head cavity, wherein a insulation layer witha preset thickness is arranged on an outer side of the sink head cavity, and casting liquid in the sink head cavity is kept in a liquid state within a preset time length so as to fill a cavity formedby shrinkage of the casting liquid in a device cavity in the forming process. The device is advantaged in that the insulation layer is arranged on the outer side of the sink head cavity, the heat dissipation rate of the casting liquid in the sink head cavity can be reduced, the casting liquid in the sink head cavity is kept in the liquid state within the preset time period so as to fill the cavityformed by shrinkage in the forming process of the casting liquid in the device cavity, and thereby the device can be effectively fed, the yield of the device is increased, and casting efficiency is improved. 本发明实施例提供一种具有高效补缩功能
