Abstract

The utility model relates to an improved forming casting die for an elevator groove wheel 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 elevator groove wheel casting; the sprue gate is communicated with the forming cavity; and the sprue gate is positioned above the center position of the core die. In the scheme, a manner of pouring in the middle of the casting is adopted, so that both a pouring temperature and a setting rate of each point on the casting are more uniform and the defects of shrinkage cavity, porosity and the like are decreased or reduced.

Description

A kind of shape casting mould of improved elevator sheave foundry goods
Technical field
The technical program belongs to casting technology field, specifically is a kind of shape casting mould of improved elevator sheave foundry goods.
Background technology
In the prior art, the elevator sheave is very high to the material requirement of foundry goods, generally all adopts high-intensity ductile iron production, because the working environment safety requirements of itself is very high, so foundry goods inside does not allow to occur defectives such as shrinkage cavity shrinkage porosity.General technology so the setting rate of each point is inconsistent on the foundry goods, is easy to produce defectives such as shrinkage cavity shrinkage porosity in the cast of the side of foundry goods.
Summary of the invention
This programme adopts the mode of cast in the middle of foundry goods, makes that pouring temperature and the setting rate of each point all compare evenly on the foundry goods, reduces or defective such as reduction foundry goods shrinkage cavity shrinkage porosity, and specifically technical scheme is as follows:
A kind of shape casting mould of improved elevator sheave 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 elevator sheave foundry goods; Described sprue gate is communicated with forming cavity; Described sprue gate is positioned at the top, center of loam core mould.
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.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model principle schematic.
Fig. 3 is the schematic side view of Fig. 2.
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, processed elevator sheave 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 elevator sheave 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 elevator sheave foundry goods; Described sprue gate is communicated with forming cavity, it is characterized in that described sprue gate is positioned at the top, center of loam core mould.
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.
