Abstract

The invention provides a new insulation riser sand mold and a moulding method thereof. So technical problems, which exist in moulding processes of traditional moulding methods and can be solved in the invention, are that a riser neck part is difficult to fill sand and the compaction of the sand is not enough because a height, a direction and a putting position of an insulation cover are difficult to control. In the invention, a technical idea of pre-embedding a riser neck even core is adopted. The method comprises the following steps: manufacturing the riser neck even core; putting the manufactured riser neck even core at the riser neck of a die; arranging the riser; arranging the insulation cover on the top of the riser neck even core; introducing and compacting the sand; solidifying the sand; and taking out a casting die and the riser die. So mouding is completed and the insulation riser in complete accordance with technological parameters is obtained. The method allows moulding efficiency to be improved, and riser feeding efficiency to be guaranteed, and has a popularization value to similar casting riser moulding.

Description

A kind of insulated feeder and formative method thereof
Technical field
The present invention relates to a kind of insulated feeder and formative method thereof.
Background technology
Traditional way is when putting feeding head on a certain foundry goods, to make a rising head mould earlier, outside apperance, put muff, muff and rising head mould directly are positioned over treat feeding correspondence position (having preestablished the spill shallow slot), as Fig. 1, put sand again, the consolidation molding sand.Because riser neck periphery A is empty to the indication position, in the operating process, A is difficult for consolidation to indication position riser neck periphery molding sand, and height dimension is wayward up and down for muff, make that muff and riser height direction are inconsistent, molding quality can not reach the requirement of process stipulation, has influence on the feeding efficiency of insulated feeder.
Adopt the conventional method moulding, rising head root tight sand difficulty, molding sand is difficult for consolidation, muff above-below direction play, size is difficult for guaranteeing that final rising head parameter and technological requirement deviation are big, has influenced the feeding effect of rising head, rarefaction defect often appears in foundry goods.
Summary of the invention
The invention provides a kind of new insulated feeder sand mold and formative method thereof, be difficult to control, make the riser neck position be difficult to back-up sand and the not enough technical problem of the degree of packing to solve traditional design method muff short transverse putting position in modeling process.
Technical scheme of the present invention is as follows:
A kind of formative method of insulated feeder may further comprise the steps:
(1) preparation riser neck mud core, the center of riser neck mud core is a cylindrical hole, the internal diameter of riser neck mud core is than the big 1~2mm of maximum outside diameter of the riser neck position of rising head mould;
What (2) riser neck mud core is placed casting die treats the feeding correspondence position, as substrate the rising head mould is installed with riser neck mud core, on the rising head mould muff is installed then;
(3) put sand, the consolidation sand mold, after the curing, riser neck mud core, molding sand natural combination are one;
(4) withdraw from casting die and rising head mould, promptly finish moulding, obtain and the on all four insulated feeder of technological parameter.
Above-mentioned riser neck mud core and molding sand all adopt resin sand.
A kind of insulated feeder that adopts above-mentioned formative method to obtain, comprise muff and be wrapped in the outer rising head main body sand mold of muff sidewall, this rising head main body sand mold is according to rising head mould and muff moulding gained, its special character is: the riser neck of described insulated feeder is made of pre-buried riser neck mud core, and described pre-buried riser neck mud core outer wrap has and the identical molding sand of rising head main body sand mould material.
Above-mentioned pre-buried riser neck mud core and rising head main body sand mold all adopt resin sand, and the two natural combination is an one.
The present invention has the following advantages:
1, this method is simple, has guaranteed the height dimension of riser neck, makes must not adjust in the modeling process to proofread and correct muff short transverse putting position, and the riser neck position is difficult to back-up sand and the not enough problem of the degree of packing is able to basic solution.
2, pre-buried riser neck mud core, the riser neck size is accurate after the moulding, the sand mold consolidation.Muff is consistent with rising head above-below direction height, effectively brings into play the feeding effect of rising head, rarefaction defect do not occur.
3, improve moulding efficient, guaranteed riser supplement shrink efficiency, similar casting pressing port moulding is had promotional value.

Fig. 2 is a riser neck mud cored structure schematic diagram of the present invention;
Fig. 3 is the schematic diagram that each parts is provided with in the modeling process of the present invention;
Fig. 4 is the schematic diagram of moulding of the present invention after finishing.
Above accompanying drawing is longitudinal cross-sectional view, the drawing reference numeral explanation:
The 1-muff; 2-rising head mould, the riser neck position of 21-rising head mould; The 3-casting die; The 4-rising head, the 41-riser neck; 5-riser neck mud core; The 6-foundry goods.
The specific embodiment
The present invention adopts the technological thought of pre-buried riser neck mud core, makes general core box one pair earlier, makes riser neck mud core.When carrying out the moulding operation, the mud core that has prepared is placed on mould riser neck position, put rising head again, muff is placed on riser neck mud core top, begin to put sand, consolidation then.Molding sand solidifies the back and takes out, and casting die and rising head mould are promptly finished the on all four insulated feeder of moulding acquisition and technological parameter.
Specific as follows:
1, do riser neck core box one pair, preparation riser neck mud core, riser neck mud core shape is as shown in Figure 2.The center of riser neck mud core is a cylindrical hole, through repeatedly test, determines that the internal diameter of riser neck mud core is more proper than the big 1~2mm of maximum outside diameter of the riser neck position of rising head mould;
2, riser neck mud core is placed in the treating on the feeding correspondence position (identical) of casting die, as substrate the rising head mould is installed, put muff again, put sand then, the tight sand moulding with riser neck mud core with the position of traditional approach.As shown in Figure 3.
3, after moulding was finished, casting die and rising head mould withdrawed from, and riser neck core and moulding are with sand and be combined as a whole, and muff is stayed and formed the true-to-size insulated feeder in the type.As Fig. 4. riser neck mud core position blanks and embodies with dotted line among Fig. 4, is that outside with it the moulding of expression riser neck mud core this moment is closely as one with sand.
Adopt the mode of above pre-buried riser neck mud core, the riser neck size is accurate after the moulding, the sand mold consolidation.Muff is consistent with rising head above-below direction height, effectively brings into play the feeding effect of rising head, rarefaction defect do not occur.Make must not adjust in the modeling process and proofread and correct muff short transverse putting position, the riser neck position is difficult to back-up sand and the not enough problem of the degree of packing is able to basic solution.
