Abstract
A hot core box molding technology of riser for casting comprises the following steps: preparing a riser hot core box; burdening, specifically uniformly heating raw materials to a high temperature, adding a hot core box resin, a curing agent and the like, and stirring uniformly; transferring the burdened material into a core making machine; installing the hot core box in the core making machine, heating and raising the temperature of the hot core box so as to reach the production requirement; turning on the core making machine for sand shooting, performing high-temperature baking; after the burdened material is solidified and forms a riser, opening the hot core box and taking out the riser. The technology helps to solve the problems that during sand-shooting type riser production, batch scraping of risers caused by deformation and only relatively small-size risers can be produced because of the wet strength of the risers; the baking procedures with a special baking apparatus are reduced, automatic production is basically realized, a large amount of labor and cost is saved, the labor intensity of operators is substantially reduced; and because the riser is taken out by demolding from a mold after solidified, the product is not easy to deform, and the dimension of the riser is extremely high in precision.
Description
Technical field
The present invention relates to casting field, relate in particular to rising head hot box forming technique technique for a kind of casting.
Background technology
During existing rising head is produced, with raw material and moulding process, distinguish, can be divided into and penetrate sand class rising head and slurry rising head.Penetrate sand class rising head, because caloric value is higher, size is relatively accurate, and is widely used in the production of middle-size and small-size foundry goods, in foundry goods such as blast pipe, turbine case, is widely used.The cold box resins such as general employing furane resins, waterglass, acrylic acid or other mixture of penetrating sand class rising head mix rear utilization and penetrate sand machine and inject in rising head mold cavity, recycle raw-material wet strength and carry out the artificial demoulding, then put into continous way or monomer drying oven baking molding.But in this process, due to the weight of die ontology, increase operating personnel's labour intensity; Owing to penetrating the fixed dimension of sand machine, limit the size of rising head, so can only produce the rising head compared with ting model; Before baking, need to have enough to meet the need and send into roasting plant wet rising head, the wet strength due to rising head in this process be less, easily causes rising head to be out of shape before week goes to drying oven and in drying oven bake process, cause Riser Dimensions to change, cause scrapping of rising head batch.
Summary of the invention
The object of the invention is, overcome prior art and have above-mentioned defect, and rising head hot box forming technique technique for a kind of casting is provided, solved and penetrated in sand class rising head production process the batch that the wet strength due to rising head causes rising head distortion to bring and scrap and can only produce compared with a difficult problem for ting model rising head, reduced the roasting procedure that uses special drying plant; Substantially realize automated production, save a large amount of labor costs, significantly reduce employee's labour intensity, because rising head is that curing and demolding is taken out in mould, so product is not yielding, Riser Dimensions precision is very high.
The technical solution adopted for the present invention to solve the technical problems is:
A rising head hot box forming technique technique for casting, comprises the following steps:
A, making rising head hot box;
B, batching: to high temperature, add hot box resin and curing agent etc. to stir raw material homogeneous heating;
C, batching week is gone in core making machine;
D, core making machine are installed hot box and to its heating, intensification, are reached production requirement;
E, startup core making machine are penetrated sand, and high-temperature baking;
F, batching sclerosis form rising head, open hot box and take out rising head.
The temperature of described b, d, e step, heat time, baking time are to determine according to the quality requirements of concrete model rising head.
Described b step is to be completed by proportioning machine.
In described e step, core making machine is the hot box core-making machine that can heat, and mode of heating can adopt gas heating or electrical heating.
The invention has the beneficial effects as follows: solved and penetrated in sand class rising head production process the batch that the wet strength due to rising head causes rising head distortion to bring and scrap and can only produce compared with a difficult problem for ting model rising head, reduced the roasting procedure that uses special drying plant; Substantially realize automated production, save a large amount of labor costs, significantly reduce employee's labour intensity, because rising head is that curing and demolding is taken out in mould, so product is not yielding, Riser Dimensions precision is very high.
