Abstract
The utility model discloses a kind of heat preserving type blind riser, the blind riser that belongs to gravity casting mould improves structure; Aim to provide the heat preserving type blind riser that one is incubated and feeding is effective, easy for installation, not fragile, foreign matter is difficult for entering.It comprises the inner blind riser body for cavity, and the steam vent being communicated with described cavity is arranged at the top of this blind riser body; Blind riser body (3) is embedded in metal-coating (1), is filled with asbestos fibre (2) in described steam vent.The utility model had not only improved the intensity of blind riser body and heat-insulating property, and but also can facilitate being connected and installed of blind riser body and mold cavity can also ensure to avoid foreign matter to fall in the unimpeded situation of exhaust and affect casting quality simultaneously.The blind riser that is a kind of gravity casting mould improves structure.
Description
Technical field
The utility model relates to a kind of casting mould, and the blind riser that relates in particular to a kind of gravity casting mould improves structure.
Background technology
As everyone knows, blind riser is a kind of rising head form adopting in gravity casting process, has certain intensity in order to be incubated and to ensure, conventionally blind riser is embedded in molding sand.Although fairly simple, this can increase mould volume, being connected and installed of rising head and mold cavity is more difficult, and easily damages.In addition, because steam vent is directly exposed in air, foreign matter easily falls into steam vent and affects casting quality.
Summary of the invention
In order to overcome the defect existing in prior art, the utility model aims to provide the heat preserving type blind riser that one is incubated and feeding is effective, easy for installation, not fragile, foreign matter is difficult for entering.
To achieve these goals, the utility model by the following technical solutions: it comprises the inner blind riser body for cavity, and the steam vent being communicated with described cavity is arranged at the top of this blind riser body; Blind riser body is embedded in metal-coating, in described steam vent, is filled with asbestos fibre.
Described cavity is inverted cone-shaped structure.
Compared with the prior art, the utility model is owing to having adopted technique scheme, at this external metal-coating that increased of blind riser, therefore not only improved the intensity of blind riser body and heat-insulating property, but also can facilitate being connected and installed of blind riser body and mold cavity; In addition, owing to being filled with asbestos fibre in steam vent, therefore can ensureing that exhaust is unimpeded, can avoid foreign matter to fall into and affect casting quality again.Moreover, the cavity of blind riser body, owing to having adopted up-small and down-big inverted cone-shaped structure, has therefore further improved insulation and feeding effect.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
In figure: metal-coating 1, asbestos fibre 2, blind riser body 3, foundry goods 4, mould 5.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
As shown in Figure 1: the blind riser body 3 by silico-calcium (B3A) compression molding is embedded in metal-coating 1, the steam vent being communicated with this blind riser body interior cavity is arranged at the top of blind riser body 3, is filled with asbestos fibre 2 in this steam vent.In order to be incubated and to improve feeding effect, the cavity of blind riser body 3 inside adopts inverted cone-shaped structure.
When use, the utility model is fixed on mould 5, ensures that the cavity of blind riser body 3 inside is communicated with mould 5.As can be seen from Figure 1, owing to adopting the up-small and down-big pyramidal structure that arrives, therefore, in the process of cast article 4, the metal liquid in blind riser body 3 internal cavities is difficult for quick cooled and solidified, thereby can improve feeding effect, raising casting quality.
Claims (2)
1. a heat preserving type blind riser, comprises the inner blind riser body for cavity, and the steam vent being communicated with described cavity is arranged at the top of this blind riser body; It is characterized in that: blind riser body (3) is embedded in metal-coating (1), in described steam vent, be filled with asbestos fibre (2).
2. heat preserving type blind riser according to claim 1, is characterized in that: described cavity is inverted cone-shaped structure.
