Abstract
The utility model discloses a thermal-insulation anti-blocking structure for a feed head, which comprises a feed head body arranged in a sand mould, and a conical bar inserted in the air outlet channel and the air outlet. An air outlet is arranged at the top of the feed head body; and an air outlet channel communicated with the air outlet is arranged at the top of the sand mould. During the casting manufacturing process, the conical bar is inserted in the air outlet, so that sand grains can be prevented from plugging the air outlet or from falling into a cavity below; and the conical bar is taken out after the molding, the air outlet is communicated with the atmosphere through the air outlet channel, and smooth air discharge can be achieved during the pouring, so that the defect of air holes on castings can be avoided.
Description
Technical field
The utility model relates to a kind of rising head.
Background technology
As shown in Figure 1, existing insulated feeder 02 is located in the sand mold 01, and insulated feeder 02 top is provided with venthole 03, and sand mold 01 top is provided with the outlet passageway 04 that communicates with venthole 03, and outlet passageway 04 is to produce with sand mold 01, and is identical with sand mold 01 material; During moulding, sand grains falls into venthole 03 from outlet passageway 04 unavoidably, stops up venthole 03 or falls into the die cavity 05 of below, brings burning into sand, defective such as is mingled with to foundry goods.
Summary of the invention
This practical problem to be solved just provides the anti-blocking structure of a kind of insulated feeder, can prevent effectively that sand grains stops up the die cavity that venthole perhaps falls into the below in the casting mold manufacture process, improves casting quality.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: the anti-blocking structure of a kind of insulated feeder; Comprise the rising head body of being located in the sand mold; Said rising head bodies top is provided with venthole, and said sand mold top is provided with the outlet passageway that is communicated with venthole, it is characterized in that: also comprise the awl rod that is inserted in outlet passageway and the venthole.
Further, said awl rod is no sharp cone distal.
Further, the cone angle of said awl rod is 3 °～5 °.
Further, the cone angle of said awl rod is 4 °.
Further, said awl rod is processed by hardwood.
The beneficial effect of the utility model: in the casting mold manufacture process, will bore rod and be inserted in the venthole, and prevent that sand grains from stopping up the die cavity that venthole perhaps falls into the below; To bore rod after moulding finishes and take out, venthole is through outlet passageway and atmosphere, and the bleb defective is avoided in exhaust smoothly during cast.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structural representation (during cast) of existing casting mold;
Fig. 2 is the structural representation (during moulding) of the utility model.
The specific embodiment
With reference to Fig. 2, the anti-blocking structure of a kind of insulated feeder comprises the rising head body of being located in the sand mold 12; Rising head body 2 tops are provided with venthole 21, and sand mold 1 top is provided with the outlet passageway 11 that is communicated with venthole 21, and outlet passageway 11 is bored rod 3 with venthole 21 interior being fitted with; Awl rod 3 is no sharp cone distal; Its cone angle is 3 °～5 °, is preferably 4 °, adopts hardwood to process; Specification requirement: bore excellent smooth surface, concavo-convex phenomenon can not be arranged.
In the casting mold manufacture process, will bore rod 3 and be inserted in the venthole 21, prevent that sand grains from stopping up the die cavity that venthole 21 perhaps falls into the below; To bore rod 3 after moulding finishes and take out, venthole 21 is through outlet passageway 11 and atmosphere, and the bleb defective is avoided in exhaust smoothly during cast.Simple in structure, easy to use.
