Abstract
The invention discloses a novel casting mold and a molding method thereof. The casting mold consists of a rotary disk (1), a base plate (2), a fixed scraping plate (3), a steel outer mold (4), steel upper mold (5), fixed shafts (6), (7) and (9) and a bracket (8). The molding method comprises the following steps of: placing a prefabricated two-sheet mold sample onto the edge of the base plate (2); matching the steel outer mold (4) and fastening; filling sand into the steel outer mold (4) and ramming; striking off a top surface with the scraping plate when the sand reaches the top surface; putting a top plate mold sample; matching the steel upper mold (5); filling sand into the steel upper mold (5) and ramming; leaving a sprue gate and an air outlet hole; opening the steel upper mold (5) and the steel outer mold (4); taking the mold sample out; and starting casting. When a second casting is required to be cast, the method comprises the following steps of: enclosing the two-sheet mold sample; filling sand into the cavity of the two-sheet mold sample; ramming; taking the mold sample away; scraping a mold cavity by rotating the rotary disk (1) and using the fixed scraping plate (3); and matching the steel outer mold (4) and the steel upper mold (5) to cast. The novel casting mold has the advantages of saved labor force, low labor intensity, high success rate, high accuracy, easiness for demolding, short flow, low time consumption and high efficiency, and is particularly suitable for casting container castings such as copper drums, boilers, basins and the like.
Description
Technical field
The present invention relates to a kind of casting mould, more particularly, the present invention relates to a kind of novel casting mould and formative method thereof
Background technology
At present, box moulding is adopted in metal casting more.Production procedure is to lay apperance and sandbox as the one of which, and type is repaired and turned in back-up sand and ramming, and the finishing die joint is placed cope, back-up sand and ramming, and finishing and open form, the finishing die joint, molding is also repaired sand mold, mould assembly.Can find out that from above-mentioned production procedure it exists following defective: the one, the tediously long complicacy of process has taken great amount of time; Two are to use two sandbox hand moulding cores up and down, and labour intensity is big; The 3rd, constantly mould turnover, molding, core are prone to be damaged in the process; The 4th, to become flexible the molding sand around the apperance during molding, the core easy deformation, and core size, surface detail etc. lose shape easily, are difficult to after casting, form accurate foundry goods.Up to the present, also there is not better solution.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide that a kind of process is simple, spended time is few, labour intensity is low, core is not fragile, the novel casting mould and the formative method thereof of core precision size.
The object of the invention is achieved through following technical proposals.
On carriage 8, establish rotating disk 1; Be fixedly connected backing plate 2 on the rotating disk 1; Backing plate 2 outer periphery are rotated the steel external mold 4 of foldings around fixed axis 6, the steel patrix 5 that an end setting of carriage 8 spins upside down around fixed axis 7, and the fixedly scraper plate 3 around fixed axis 9 activities is established in the appropriate location of carriage 8.
Formative method is: the cope and drag pattern appearance that will make in advance is placed on backing plate 2 limits on the rotating disk 1, and the steel external mold 4 that closes then, steel adventitia 4 back of closing is fastening and compress the two-piece type apperance through compressing member through screw rod; Irritate the sand and the reality of pounding then in the chamber of two-piece type apperance and between steel adventitia 4 and two-piece type apperance, when arriving end face, end face is wipeed off with scraper plate; Put the top board apperance, the steel patrix 5 that closes is then irritated sand rammer in fact again; Reserve sprue gate and venthole, film 5 on the steel that up overturns is then opened steel adventitia 4; Take out two-piece type apperance and top board apperance, film 5 on close again steel adventitia 4 and the steel can be cast.When casting second during with later foundry goods; Only need place the two-piece type apperance; In two-piece type apperance chamber, irritate sand rammer in fact, take the two-piece type apperance away, again through rotating disk 1 rotation and the fixedly acting in conjunction of scraper plate 3; Just can scrape and make casting mold cavity, the steel adventitia 4 that closes can be cast with steel patrix 5 in succession.
The invention has the beneficial effects as follows:
1, steel external mold 4 and the 5 rotatable foldings of steel adventitia, having avoided box moulding, common lift the big problem of labour intensity that case, mould turnover cause.Simultaneously, this new formative method, a people promptly can carry out moulding work, and if box moulding meets massive casting because the sandbox volume is big, weight is big, all wants two people could accomplish above the cooperation usually.Have that labour intensity is low, the characteristics of labor savings.
2, because new die and formative method thereof need not lifted case, mould turnover, the loosening demoulding etc., thereby have the power of being shaped to height, precision is accurate, high, is easy to advantages such as the demoulding.
3, because steel external mold 4 and steel patrix 5 its apperance when first time moulding is fixing; When second time moulding, only needing to go out the die cavity steel external mold 4 that can close through rotating disk 1 and fixing scraper plate 3 acting in conjunction strikings just can cast with steel patrix 5; Thereby flow process is short, and the time is few, and efficient is high; Be particularly suitable for casting container class foundry goods, like bronze drum, pot, basin etc.
Description of drawings
Accompanying drawing is a novel casting mould structure sketch map of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further elaboration.
Embodiment 1: on carriage 8, establish rotating disk 1, rotating disk 1 can manually also can be electronic; Be fixedly connected backing plate 2 on the rotating disk 1, be fixedly connected ribs on the backing plate 2, in order to strengthen the moulding intensity of core; Backing plate 2 outer periphery can be established ribs around 2 steel external molds 4 of fixed axis 6 rotation foldings in the steel external mold 4, and in order to strengthen moulding intensity, steel external mold 4 peripheral hardware fastening screw keyholes are through the steel external mold 4 fastening location of fastening bolt with closure; Corresponding after the steel patrix 5 that one end setting of carriage 8 spins upside down around fixed axis 7, steel patrix 5 close with the size of steel external mold 4, establish ribs in the steel patrix 5, in order to strengthen fixedly molding sand; The fixedly scraper plate 3 around fixed axis 9 activities is established in the appropriate location of carriage 8, and fixedly the head striking shape of scraper plate 3 is corresponding with the shape of apperance die cavity.Fixedly scraper plate 3 can up-down adjustment be fixedly clamped on fixed axis 9.
Its formative method is: the two-piece type apperance that will perform in advance is placed on backing plate 2 limits on the rotating disk 1, and the steel external mold 4 that closes then, steel external mold 4 back of closing is fastening and compress the two-piece type apperance through compressing member through screw rod; Irritate the sand and the reality of pounding then in the chamber of two-piece type apperance and between steel external mold 4 and two-piece type apperance, when arriving end face, end face is wipeed off with scraper plate; Put the top board apperance, the steel patrix 5 that closes is then irritated sand rammer in fact again; Reserve sprue gate and venthole, the steel patrix 5 that up overturns is then opened steel external mold 4; Take out two-piece type apperance and top board apperance, close steel external mold 4 and steel patrix 5 can be cast again; When casting second during with later foundry goods; Only need place the two-piece type apperance; In two-piece type apperance chamber, irritate sand rammer in fact, take the two-piece type apperance away, through rotating disk 1 rotation and the fixedly acting in conjunction of scraper plate 3; Just can scrape and make casting mold cavity, the steel external mold 4 that closes can be cast with steel patrix 5 in succession.
