Abstract
The utility model relates to a sand mould for a casting stainless steel flange, which is composed of an upper model mould and a lower model mould. The model moulds are provided with side risers. The part close to one riser is provided with a pouring opening. The utility model is characterized in that the bottom part of a model chamber of the lower model mould is provided with two to one hundred cooling iron blocks and the top part of the upper model mould is provided with a circle of thermal-insulating cotton. The utility model can produce the casting stainless steel flange with high quality in order to enable the production of the stainless steel flange to obtain high material utilization, less occupied land, low manufacture cost and short periodicity.
Description
The utility model relates to the metallurgical casting technology, and a kind of sand mold structure that is used to cast high-performance, high reliability steel flange is provided especially.
The GIS tank body is very high to the requirement of flange, need have anti intercrystalline corrosion performance and superior corrosion resistance energy and cold-forming property preferably, and requiring has the welding performance good with other stainless steels, and has non magnetic.To high performance flange like this, all be with the cutting of stainless steel materials plasma in the prior art, machine adds and forms, and its shortcoming is that stock utilization is low, is about 30%; Complex procedures and occupied ground; The production cost height; Production cycle is long.
The purpose of this utility model is to provide a kind of cast stainless steel flange sand mold, and it can produce high-quality cast stainless steel flange, thereby makes the production of steel flange, the stock utilization height, and occupied ground is few, and production cost is low, and is with short production cycle.
The utility model provides a kind of cast stainless steel flange sand mold, constitute by upper and lower pattern (1) (2), side riser (3) is set on the pattern, be provided with cast gate (4) near one of them rising head, it is characterized in that: anvil swage (2) cavity bottom is provided with 2～100 blocks of chills (5), and mo(u)ld top half film (1) die cavity top is provided with a circle heat-preservation cotton (6).
In addition, chill in the utility model (5) is emitting oral region near endoporus, and end region reaches center line deeply, other chills in this way gradually transition arrange.
Heat-preservation cotton is arranged at the neighboring at die cavity top in the utility model, reaches center line deeply.
The utility model is controlled the consecutive solidification of foundry goods effectively by adopt to accelerate the cooling of sealing position and delay the way of non-tight position cooling, makes the position even tissue refinement of sealing, and defective is gone into for ground be controlled at the non-tight position.Install on the GIS tank body by the flange of the utility model production and experiment showed, that complete energy substitutes sheet material processing method orchid and satisfies instructions for use, casting and forging are developing direction of metal material, thereby have important popularizing application prospect.By embodiment in detail the utility model is described in detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is the cut-away view of cast stainless steel flange with sand mold.
Accompanying drawing 2 is the configuration diagram of anvil swage.
Accompanying drawing 3 is the configuration diagram of top swage.
Embodiment
As shown in Figure 1, the cast flange sand mold is made of upper and lower pattern (1) (2), and anvil swage (2) cavity bottom is provided with chill (5), and top swage (1) die cavity top is provided with a circle heat-preservation cotton (6); Accompanying drawing 2 is seen in arranging of chill (5).In zone near rising head (3), chill (5) one ends are near endoporus, the other end is imbedded pattern, end region is promptly cooled off in mid point district at two rising heads (3), chill (a 5) part is a cavity bottom, another part is imbedded pattern, and chill (5) can reach the center line position at most, and gradually arrange in this way by transition for other chills (5).Accompanying drawing 3 is seen in being provided with of heat-preservation cotton (6), places the neighboring of die cavity, can reach center line deeply.
Claims (3)
1. cast stainless steel flange sand mold, constitute by upper and lower pattern (1) (2), side riser (3) is set on the pattern, be provided with cast gate (4) near one of them rising head, it is characterized in that: anvil swage (2) cavity bottom is provided with 2～100 blocks of chills (5), and mo(u)ld top half film (1) die cavity top is provided with a circle heat-preservation cotton (6).
2. by the described cast stainless steel flange of claim 1 sand mold, it is characterized in that: chill (5) is emitting the close endoporus of oral region, and end region reaches center line deeply, other chills in this way gradually transition arrange.
3. by the described cast stainless steel flange of claim 1 sand mold, it is characterized in that: heat-preservation cotton is arranged at the neighboring of die cavity, reaches center line deeply.
