Abstract
The utility model discloses a core bone for cylinder body casting, including the core bone body, two links of core bone body parcel respectively have the temperature resistant soft materials. The utility model discloses a wrap up temperature resistant soft materials respectively at two links of core bone body, like this when the casting, along with the inflation of core bone, temperature resistant soft materials can be compressed, vacates the space for the core bone inflation to prevent that the core bone from rising the crack with water jacket psammitolite. The method is suitable for casting the cylinder body.
Description
Technical field
The utility model relates to a kind of parts for the cylinder body casting, particularly relates to a kind of arbor for the cylinder body casting.
Background technology
Before the utility model proposes, general cylinder body all contains jacket structure for water, and this jacket structure for water adopts the sand core of water jacket casting to form.For the intensity that guarantees sand core of water jacket with prevent from pouring into a mould rear foundry goods cylinder barrel distortion, generally can in the middle of sand core of water jacket, add arbor.But because in casting process, arbor and sand core of water jacket at high temperature can produce thermal expansion, and the arbor thermal coefficient of expansion is metal than the large 0.4(arbor of sand core of water jacket thermal coefficient of expansion), so arbor easily is split up sand core of water jacket, cause coating or sand grains to come off, so that the problems such as blemish or the rear seepage of processing appear in foundry goods.
The utility model content
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, to provide a kind of simple in structure, and is easy to use and do not affect the arbor that is used for the cylinder body casting of casting yield.
In order to realize above purpose, a kind of arbor for the cylinder body casting that the utility model provides comprises the arbor body, and described arbor body two links are enclosed with respectively the heatproof soft material.By wrapping up respectively the heatproof soft material at arbor body two links, when casting, along with the expansion of arbor, the heatproof soft material can be compressed, is arbor expansion vacating space, to prevent arbor sand core of water jacket is split up like this.
In such scheme, described heatproof soft material is asbestos, certainly also can adopt other heatproof soft materials.
In such scheme, the thickness of described heatproof soft material is 1 ~ 3mm.
The utility model is by wrapping up respectively the heatproof soft material at arbor body two links, and when casting, along with the expansion of arbor, the heatproof soft material can be compressed, is arbor expansion vacating space, to prevent arbor sand core of water jacket is split up like this.
The utility model is compared with the prior art, and shows that fully its superiority is: simple in structure, easy to use, cost is low and do not affect casting yield etc.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.
The present embodiment provides a kind of arbor for the cylinder body casting, comprises arbor body 1, and 1 liang of link of described arbor body is enclosed with respectively heatproof soft material 2.By wrapping up respectively heatproof soft material 2 at 1 liang of link of arbor body, when casting, along with the expansion of arbor 1, heatproof soft material 2 can be compressed, is arbor 1 expansion vacating space, to prevent arbor 1 sand core of water jacket 3 is split up like this.Described heatproof soft material 2 is asbestos, certainly also can adopt other heatproof soft materials.The thickness of described heatproof soft material 2 is 1 ~ 3mm.
The utility model is by wrapping up respectively heatproof soft material 2 at 1 liang of link of arbor body, and when casting, along with the expansion of arbor 1, heatproof soft material 2 can be compressed, is arbor 1 expansion vacating space, to prevent arbor 1 sand core of water jacket 3 is split up like this.
Claims (3)
