Abstract
The invention discloses an evaporative pattern casting encasement structure and an evaporative pattern casting encasement method, in particular to the evaporative pattern casting encasement structure and the evaporative pattern casting encasement method suitable for the casting field of small evaporative pattern castings. The evaporative pattern casting encasement structure can increase the yield of the evaporative pattern castings and comprises a box body, the evaporative pattern castings and a quartz sand filling layer, wherein the evaporative pattern castings are located in the box body, and the distance between every two adjacent evaporative pattern castings ranges from 30 mm to 50 mm. The evaporative pattern casting encasement method can increase the yield of the evaporative pattern castings and comprises the steps of A, placing the evaporative pattern castings into the box body and enabling the distance between every two adjacent evaporative pattern castings to range from 30 mm to 50 mm; B, filling the box body with quartz sand and carrying out jolt ramming through a vibrating table. According to the evaporative pattern casting encasement structure and the evaporative pattern casting encasement method, the phenomenon that the castings adhere to one another or are not formed in the pouring process of the evaporative pattern castings is effectively prevented, and the yield of the castings is increased by more than 50% compared with the prior art.
Description
Technical field
The present invention relates to a kind of evaporative pattern vanning structure and evaporative pattern packing method, the method for especially a kind of vanning structure of the evaporative pattern for smallclothes lost foam casting field and evaporative pattern packing method.
Background technology
Lost foam casting is the new technology of a kind of Near net shape, precise forming, this technique.Without the need to delivery, without die joint, without core, thus foundry goods does not have overlap, burr and pattern draft, and decreases the scale error caused due to core combination.The expense of the thick minimizing machining of cast(ing) surface, compares with conventional casting methods, can reduce by the machining time of 40% to 50%, therefore be widely used.Lost foam casting is the process of an operation versus busy, comprise the operations such as drawing mapping, sample making, modelling, stenciling coating, baking, vanning, smelting cast, mould preparation, heat treatment, and the control of each operation there is larger impact to casting quality.But the binning process of evaporative pattern is extremely important, but mold setting does not install, can go out the situations such as foundry goods is not shaping, adhesion, cause all process steps above all to be wasted, the lumber recovery of evaporative pattern especially smallclothes evaporative pattern is the hot issue that lost foam casting field does not solve for a long time.In the prior art evaporative pattern smallclothes in casting process, be easy to occur the adhesion between foundry goods, the problem such as not shaping, thus cause evaporative pattern smallclothes lumber recovery too low, output is too low, increases production cost.Therefore, also do not have in prior art a kind ofly effectively to prevent the adhesion between evaporative pattern casting process medium casting, the phenomenon such as not shaping, thus improve evaporative pattern vanning structure and the evaporative pattern packing method of evaporative pattern lumber recovery.
Summary of the invention
Technical problem to be solved by this invention is to provide and a kind ofly effectively can prevents the adhesion between evaporative pattern casting process medium casting, the phenomenon such as not shaping, thus improves the evaporative pattern vanning structure of evaporative pattern lumber recovery.
The present invention solves the evaporative pattern vanning structure that its technical problem adopts, comprise casing, evaporative pattern and quartz sand packed layer, described evaporative pattern is arranged in casing, and described quartz sand packed layer is filled in the gap between casing and evaporative pattern, and the spacing between described adjacent evaporative pattern is 30mm-50mm.
The present invention also provides a kind of effectively can prevent the adhesion between evaporative pattern casting process medium casting, the phenomenon such as not shaping, thus improves the evaporative pattern packing method of evaporative pattern lumber recovery.
The present invention solves the evaporative pattern packing method that its technical problem adopts, and comprises following step,
A, evaporative pattern is put into casing, make the spacing between adjacent evaporative pattern be 30mm-50mm;
B, in casing, fill full quartz sand, and carry out jolt ramming by shake table;
The invention has the beneficial effects as follows: the evaporative pattern vanning structure and the evaporative pattern packing method that adopt the application, effectively prevent the adhesion between evaporative pattern casting process medium casting, the phenomenon such as not shaping by the method adjusting spacing between adjacent evaporative pattern, make casting output improve more than 50% compared to existing technology.
Detailed description of the invention
Evaporative pattern vanning structure of the present invention, comprise casing, evaporative pattern and quartz sand packed layer, described evaporative pattern is arranged in casing, and described quartz sand packed layer is filled in the gap between casing and evaporative pattern, and the spacing between described adjacent evaporative pattern is 30mm-50mm.
The evaporative pattern packing method of making of the present invention above-mentioned evaporative pattern vanning structure, comprises following step:
A, evaporative pattern is put into casing, make the spacing between adjacent evaporative pattern be 30mm-50mm;
B, in casing, fill full quartz sand, and carry out jolt ramming by shake table.
Embodiment 1: the evaporative pattern made is put into casing, disposable in casing place 20 evaporative patterns, adjust the spacing between adjacent evaporative pattern, make spacing between evaporative pattern between 45mm to 46mm, then casing is filled full with quartz sand, and carry out jolt ramming by shake table, then through smelting the operation such as cast, mould preparation, heat treatment, finally the foundry goods obtained is tested, wherein have 16 qualified, with adopt 10 of prior art qualified compared with, certified products output adds 60%.
Embodiment 1: the evaporative pattern made is put into casing, disposable in casing place 30 evaporative patterns, adjust the spacing between adjacent evaporative pattern, make spacing between evaporative pattern between 39mm to 41mm, then casing is filled full with quartz sand, and carry out jolt ramming by shake table, then through smelting the operations such as cast, mould preparation, heat treatment, finally the foundry goods obtained is tested, wherein have 25 qualified, with adopt 16 of prior art qualified compared with, certified products output adds 56.25%.
Through lot of experiment validation, prove the evaporative pattern vanning structure and the evaporative pattern packing method that adopt the application, effectively prevent the adhesion between evaporative pattern casting process medium casting, the phenomenon such as not shaping by the method adjusting spacing between adjacent evaporative pattern, make casting output improve more than 50% compared to existing technology.
