Abstract
The utility model relates to an improved forming casting die for a flange casting, which comprises an upper die, a lower die and a core die. The upper die comprises an upper flask and an upper die sand mold in the upper flask; the upper die sand mold is provided with a sprue gate; the core die is connected with the upper die sand mold; the lower die comprises a lower flask and a lower die sand mold in the lower flask; in the state that the upper die and the lower die are assembled, a cavity is reserved between the core die and the lower die sand mold and the cavity is a forming cavity for the processed flange casting; the sprue gate is communicated with the forming cavity; the upper die sand mold is provided with a cooling body placement tank; the cooling body placement tank is correspondingly positioned above the position of an assembling hole of the processed flange casting; and cooling bodies are placed in the cooling body placement tank. In the scheme, a structure of placing chillers at the specific positions of a flange surface is adopted and the positions for placing the chillers are reserved on the die, so that the positions for placing the chillers are firstly solidified after being poured and the defects of shrinkage cavity and shrinkage porosity cannot be generated or can be reduced in the regions in which the chillers are placed.
Description
Technical field
The technical program belongs to casting technology field, specifically is a kind of shape casting mould of improved flange type foundry goods.
Background technology
In the prior art, flange type foundry goods itself requires to bear bigger pressure in actual environment for use, so do not allow to have in foundry goods inside the defective of shrinkage cavity shrinkage porosity.Ordinary circumstance all needs boring (being flange mounting hole) at these position work in-processes, thus in a single day in these positions internal flaw appears, all very big to foundry goods and cost of processing loss.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, this programme adopts the structure of placing chill at the flange face ad-hoc location, reserve the position of placing cooling body (for example chill) at mould, make the position of placing chill after cast, solidify earlier, just can or not reduce shrinkage porosity defect of contraction cavity in these zones of placing chill.Concrete technical scheme is as follows:
A kind of shape casting mould of improved flange type foundry goods comprises upper die and lower die and loam core mould; Described patrix comprises the last model sand mold in cope and the cope, has the sprue gate at last model sand mold; The loam core mould is connected with last model sand mold; Described counterdie comprises the following model sand mold in drag box and the drag box; Described under upper and lower mould confined state, leave cavity between loam core mould and the following model sand mold, cavity is the forming cavity of processed flange type foundry goods; Described sprue gate is communicated with forming cavity; Be provided with the cooling body standing groove at last model sand mold, this cooling body standing groove is positioned at the top corresponding with the pilot hole position of processed flange type foundry goods; Lay cooling body in the described cooling body standing groove.
Described upper and lower sandbox is provided with corresponding pin-and-hole and rigging pilotage outward; Under upper and lower mould confined state, the pin-and-hole of the correspondence that upper and lower sandbox is outer connects by rigging pilotage.
Described cooling body is the material of cooling iron block or other good heat conduction effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model principle schematic.
Among the figure: 1, drag box; 2, counterdie; 3, alignment pin; 4, loam core mould; 5, patrix; 6, sprue gate; 7, go up model sand mold; 8, cope; 9, following model sand mold; 10, cooling iron block; 11, processed flange correspondence position signal.
The specific embodiment
The technical program is further specified as follows below in conjunction with accompanying drawing and the specific embodiment:
A kind of shape casting mould of improved flange type foundry goods comprises upper die and lower die and loam core mould; Described patrix comprises the last model sand mold in cope and the cope, has the sprue gate at last model sand mold; The loam core mould is connected with last model sand mold; Described counterdie comprises the following model sand mold in drag box and the drag box; Described under upper and lower mould confined state, leave cavity between loam core mould and the following model sand mold, cavity is the forming cavity of processed flange type foundry goods; Described sprue gate is communicated with forming cavity, it is characterized in that being provided with the cooling body standing groove at last model sand mold, and this cooling body standing groove is positioned at the top corresponding with the pilot hole position of processed flange type foundry goods; Lay cooling body in the described cooling body standing groove.
Described upper and lower sandbox is provided with corresponding pin-and-hole and rigging pilotage outward; Under upper and lower mould confined state, the pin-and-hole of the correspondence that upper and lower sandbox is outer connects by rigging pilotage.
