Abstract

The utility model relates to an improved forming casting die for valve body castings, which comprises an upper die, a lower die and core dies. 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; cavities are reserved between the core dies and 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, cavities are reserved between the core dies and the lower die sand mold; the cavities between the core dies and the upper and lower die sand molds are forming cavities for the processed valve body castings; and the sprue gate is communicated with the forming cavities. The improved forming casting die is characterized in that two identical core dies are provided; the two core dies are arranged in parallel; the two core dies are connected by a load carrying core; and handwheel rotating shafts of the processed valve body castings are positioned at the position of the load carrying core. Adoption of the manner of the scheme can improve a supporting force and strength of the core and is greatly helpful for solving or reducing the problem of core floating.

Description

A kind of shape casting mould of improved valve body class foundry goods
Technical field
The technical program belongs to casting technology field, specifically is a kind of shape casting mould of improved valve body class foundry goods.
Background technology
In the prior art, valve body class foundry goods is because environment for use itself, and the wall thickness of valve body moulding is had size tolerance requirements.General formative technology all can produce the phenomenon of floating core, is easy to cause the wall unevenness of mo(u)ld bottom half even foundry goods directly to scrap.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, this programme adopts the scheme in the loam core of carrying a load, and is specially adapted to valve body class foundry goods and prevents floating core.Adopt a mould two caves (mould two chambeies) at mould, the loam core of carrying a load is used in two caves, namely becomes a loam core by original independent two loam core disjunctors.Adopt this mode, can improve support force and the intensity in loam core, be very helpful to solving or reducing floating core.Concrete technical scheme is as follows:
A kind of shape casting mould of improved valve body class 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; Leave cavity between loam core mould and the 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 between described loam core mould and the upper and lower model sand mold is the forming cavity of processed valve body class foundry goods; Described sprue gate is communicated with forming cavity; Described loam core mould has identical two, and two loam core moulds are arranged in parallel, and two loam core moulds connect by the loam core of carrying a load; The carry a load position in loam core is the handwheel rotating shaft position of processed valve body class foundry goods.
Described sprue gate is positioned at the top, center of two loam core moulds.
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.
Among the figure: 1, drag box; 2, counterdie; 3, alignment pin; 4, loam core mould; 4.1, the loam core of carrying a load; 5, patrix; 6, sprue gate; 7, go up model sand mold; 8, cope; 9, following model sand mold; 10, processed valve body class foundry goods.
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 valve body class 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; Leave cavity between loam core mould and the 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 between described loam core mould and the upper and lower model sand mold is the forming cavity of processed valve body class foundry goods; Described sprue gate is communicated with forming cavity; Described loam core mould has identical two, and two loam core moulds are arranged in parallel, and two loam core moulds connect by the loam core of carrying a load; The carry a load position in loam core is the handwheel rotating shaft position of processed valve body class foundry goods.
Described sprue gate is positioned at the top, center of two loam core moulds.
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.
