Abstract
The invention relates to a sand mold casting technology comprising steps that: modeling sand is manufactured, wherein casting sand with a size of 40-70 meshes are added to 1-3% of water glass; the mixture is uniformly mixed in a fracturing blender; molding and core-making are carried out; a manufactured mould cavity is vibrated on a vibration platform; casting is carried out during vibration; when a metal solution starts to solidify, the vibration step is stopped. The equipment suitable for the sand mold casting technology comprises a lower platform rack which is used for supporting an upper platform rack used for bearing the mould cavity, wherein the supporting is realized by using a rubber spring. A high-frequency motor used for generating vibration is arranged on the upper platform rack. The equipment and the technology are advantaged in that: the technology and the equipment are environment-friendly; reproducibility for used sand recycling is good; and collapsibility of used sand is good.
Description
Technical field
The present invention relates to the equipment of a kind of sand casting technology and vibrating casting thereof.
Background technology
Coal dust decomposes in the green-sand discharges a large amount of toxic gases such as BaP, dioxin, hydrogen sulfide, carbon monoxide etc., pollutes the most serious; Furane resins and phenolic resins produce strong impulse property smell such as sulfur dioxide, sulfur trioxide, nitric oxide etc. in the resin sand in moulding and casting cycle; Especially produce dioxin with furans, in bad border, can not and cause severe contamination by the biology decomposition to environment; Waterglass is cheap, and nontoxic odorless does not burn, and in mulling, moulding and casting cycle, can not produce pernicious gas, but there are collapsibility and old sand reuse two hang-ups of regenerating in water-glass sand.And existing metal casting is in casting cycle; Because sandbox or mold remain static; Bubble in the metallic solution is difficult to overflow, be unfavorable for the come-up of slag inclusion, thereby makes finished product cast be prone to produce defectives such as bubble, slag inclusion, loose, crackle, has a strong impact on the quality of cast article.
Summary of the invention
The present invention will overcome the above-mentioned shortcoming of existing sand casting technology and equipment thereof, and a kind of environmental protection, old sand reuse reproducibility is good, collapsibility is good sand casting technology and equipment thereof are provided.
Sand casting technology of the present invention comprises the steps:
Step 1 is made molding sand, adopts 40～70 purpose mound sand, adds 1%～3% waterglass, after mixing in the puddle mixer;
Step 2, moulding;
Step 3, coremaking;
Step 4 is positioned over the die cavity of making on the shaking platform and vibrates;
Be applicable to the equipment of above-mentioned sand casting technology, it is characterized in that: comprise the lower platform frame, described lower platform frame supports the upper mounting plate frame that is used to carry die cavity through rubber spring, and the high-frequency electric machines that causes vibration is housed on the described upper mounting plate frame.
According to the different phase of material behavior, foundry goods size and the casting cycle of casting metals, vibration frequency, the time of vibration of high-frequency electric machines is set.The method can effectively be improved metal casting and produce defectives such as bubble, slag inclusion, loose, crackle, can also reduce system's occupancy volume of metal in the casting pressing port, saves production cost.
Advantage of the present invention is: solved in the existing all kinds of sand casting and produced toxic gas, destroyed the problem of ecological environment; Solved the sodium silicate sand collapsibility difference and reclaimed difficult problem, practiced thrift production cost with regeneration; Reduce defectives such as existing cast article bubble, slag inclusion, loose, crackle, reduced existing running and feeding system to account for the overweight problem of foundry goods ratio, made whole casting cost obtain reducing greatly, saved energy consumption.

The specific embodiment
With reference to accompanying drawing: 1-container of molten metal, 2-metallic solution, 3-cast gate, 4-rising head, 5-foundry goods die cavity, 6-shaking platform, 7-rubber spring, 8-high-frequency electric machines, 9-upper mounting plate frame, 10-lower platform frame
Sand casting technology of the present invention comprises the steps:
Step 1 is made molding sand, adopts 40～70 purpose mound sand, adds 1%～3% waterglass, after mixing in the puddle mixer;
Step 2, moulding;
Step 3, coremaking;
Step 4 is positioned over the die cavity of making on the shaking platform and vibrates;
Be applicable to the equipment of above-mentioned sand casting technology, it is characterized in that: comprise lower platform frame 10, described lower platform frame 10 supports the upper mounting plate frame 6 that is used to carry die cavity 5 through rubber spring 7, and the high-frequency electric machines 8 that causes vibration is housed on the described upper mounting plate frame 6.
Particularly, this equipment is equipped with 4 high-frequency excitation motors, and 4 rubber springs are through the not specification vibration up and down of last lower platform generation.4 motors symmetry respectively are installed in the upper mounting plate frame 6 times, through being flexible coupling of rubber spring 7, having realized the vibration of equipment and have kept whole stable.
According to the different phase of material behavior, foundry goods size and the casting cycle of casting metals, vibration frequency, the time of vibration of high-frequency electric machines is set.The method can effectively be improved metal casting and produce defectives such as bubble, slag inclusion, loose, crackle, can also reduce system's occupancy volume of metal in the casting pressing port, saves production cost.
