Abstract
The invention relates to a moulding process for horizontal moulding and vertical casting of plate castings, which is characterized in that: the moulding method for the plate castings is horizontal moulding, a casting system of a mould is arranged according to a vertical casting process, and a sand box matched with the castings is provided with corresponding water inlet and riser according to the casting system of the mould; and the vertical casting process is adopted during casting. The moulding process has the advantages that: the occupied area of vertical casting is only 1/3 of that of horizontal casting; and in the vertical casting, molten iron is gradually cooled from bottom to top, so that gas and impurities in a cavity are discharged upwards; therefore, the surface quality of the castings is ensured and the finished product ratio of the castings is improved.
Description
Technical field
The invention belongs to casting technique, relate in particular to the formative technology that a kind of suitable resin sand line is produced the horizontal moulding pouring in vertically clamped moulds of plate class foundry goods.
Background technology
The resin sand line produce plate class foundry goods as: the aside-liner in cement, the pitch a mixing bowl, its thickness are relatively thinner, area is big, surface quality requires than higher.The aside-liner that the cylinder inner surface of cement a mixing bowl is provided with is to be used for stoping cement friction stir cylinder, to increase the service life of a mixing bowl.Aside-liner adopts casting technique to make.The forging type of all horizontal moulding of employing of factory, casting on flat is produced at present.The shortcoming of the formative technology of casting on flat is: 1, the occupation of land space of production distribution is big, and as the sand mold piece of long 900mm, wide 600mm, high 20mm, it is 0.54 square metre that the putting of casting on flat accounts for the ground area; 2, modeling process complexity.Need the operator could begin to put sand to mouth of a river rod, rising head rod, the rod of giving vent to anger after all will putting during horizontal moulding, also will press when putting sand, prevent that the mouth of a river, rising head are crooked with hand by technological requirement; Simultaneously in order to prevent that casting deformation from also needing to put chill in sand mold.Operating procedure complexity, the distortion of foundry goods are still very big; 3, the surface quality of foundry goods is poor.The aside-liner area is bigger and thickness is thinner, and the gas during casting on flat in the molten iron can not well be got rid of, very easily occur choking defective.In a single day dirt in the molten iron enters in the die cavity, causes then that cast(ing) surface is large-area to scab, and local little defective causes whole foundry goods to scrap.Foundry industry demands researching and developing a kind of casting technique of being out of shape the large-scale thin plate class little, that technology is simple, surface quality is high urgently.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, and a kind of formative technology of being out of shape the horizontal moulding pouring in vertically clamped moulds of plate class foundry goods little, that technology is simple, surface quality is high is provided, be specially adapted to the aside-liner castings production that thickness is relatively thinner in cement, the pitch a mixing bowl, area is big, surface quality is had relatively high expectations.
The present invention for achieving the above object, by the following technical solutions: the formative technology of the horizontal moulding pouring in vertically clamped moulds of a kind of plate class foundry goods, it is characterized in that: the formative method of plate class foundry goods is horizontal moulding, the running gate system of mould is by the pouring in vertically clamped moulds technology arrangement, and the matching used sandbox of foundry goods is made corresponding water, rising head position according to the running gate system of mould; Adopt pouring in vertically clamped moulds technology during cast.
The technological process of horizontal moulding pouring in vertically clamped moulds combination is as follows:
1, make mould earlier, die and casting system arrangement will be made by the technology of pouring in vertically clamped moulds;
2, after mould is finished, mould is placed on the active line, blows off floating sand;
3, the placement of sandbox: the position, the mouth of a river on the mouth of a river position alignment template when putting sandbox on the sandbox, and the positioning strip of sandbox installed;
4, put sand: make die surface fill sand fast when putting sand, make real with hand;
5, lift: after sand mold solidified 15 minutes, with the steady lift of overhead traveling crane;
6, spacious case: behind the spacious case, in the inspection type zero defect is arranged, need will polishing flat of polishing, need the repairing of repairing;
7, following core: after wiping fash off, following core;
8, spraying: coating will stir, and the brush facade is brushed big face then earlier, is as the criterion can't see black sand;
9, oven dry, mould assembling, top box card, vertically put sand mold;
10, by pouring in vertically clamped moulds technology castable.
Beneficial effect: the pouring in vertically clamped moulds floor space is: 0.18 square metre, only account for 1/3 of casting on flat floor space.And during the pouring in vertically clamped moulds moulding, the operator need not put the mouth of a river, rising head, chill etc., and to pile sandbox just passable as long as sand made real, and shortened the moulding time greatly, improved operating efficiency.Yet pouring in vertically clamped moulds, molten iron be cooling gradually from bottom to top, makes interior gas of die cavity and impurity from last eliminating, thereby guarantees the surface quality of foundry goods, improves finished casting rate.
