Abstract
The utility model relates to a casting mold for preventing bulging; comprising a mold base (4), a cavity (2) and a casting head (1); the casting mold is characterized in that: the casting mold also comprises an air outlet hole (3), the cavity (2) is matched with the mold base (4), the middle part of the cavity (2) is provided with the casting head (1), and the air outlet holes (3) are respectively arranged on the cavity (2) and at two sides of the casting head (1). The casting mold has simple process steps and easy operation, can effectively prevent bulging in the casting process; the design of the mold is scientific, the structure is simple and the effect is remarkable, and the mold can effectively exhaust the air in the cavity; the mold has high intensity and is not easy to damage, thereby being beneficial to inhibiting the bulging.
Description
Technical field
The utility model relates to the casting field of metal, especially relates to a kind of improvement that prevents the casting mould of bulging.
Background technology
When adopting present casting mould to carry out Foundry Production, as easy as rolling off a log generation swelling, especially when the bigger and thicker tabular foundry goods of casting area, its expansion is more obvious.Because the die cavity of formwork is bigger, when molten steel injected die cavity fast, the gas in the die cavity can not be got rid of in time, refluxed thereby form, and was formed centrally the powerful bulbs of pressure in refluxing.At these positions,, then produce and expand if the pressure that the bulbs of pressure at this position of strength ratio of formwork produce is little.For this reason, the someone has adopted dead head has been placed in the thermal center place, eliminates shrinkage cavity and shrinkage porosite phenomenon; Method with method that adds foundary weight and inclined casting prevents platform case phenomenon.Because formwork hollow, when foundary weight was added to constant weight, formwork can be pressed to subside, and form big pit, and near bulging is very high, makes this product rejection.
The utility model content
The utility model provides a kind of casting mould of expanding of preventing in casting process, be easy to produce in casting process and expand thereby solved existing in prior technology, and product rejection rate is higher, the technical problem that production cost is big; The structure that has solved simultaneously the existing in prior technology formwork again is very unreasonable, and intensity is not high, is easy to breakage, the anti-bad technical problem of expansion character.
For achieving the above object, the technical solution of the utility model is as follows:
Prevent the casting mould of bulging, comprise mould bases, die cavity, dead head is characterized in that, also comprises venthole, and described die cavity and mould bases are matched, and the middle part of die cavity is provided with dead head, is respectively equipped with venthole on die cavity and in the both sides of dead head.
Described die cavity is made of several layers, is provided with a back-up coat therebetween at least.
The quantity of back-up coat can be determined according to actual needs.
Described back-up coat is located between 3～6 layers of die cavity.
The network structure that described reinforcing series of strata are worked out by some steel wires.
Described mould bases both sides be respectively equipped with can be matched with column through hole.
On described through hole, be provided with guide way.
The opening of described dead head is made as horn-like.
Described venthole is provided with blast pipe.
Venthole on the described die cavity has two.
Venthole on the described die cavity is symmetrical.
Beneficial effect:
1, processing step is simple, and is easy to implement;
2, prevented the swelling in the casting process effectively;
3, the Mould design science is simple in structure, and effect is obvious, effectively the gas in the die cavity is discharged; 4, mould strength is higher, and is not fragile, helps repression of swelling.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As Fig. 1, shown in 2,3, prevent that the casting mould of bulging from comprising mould bases 4, the die cavity 2 matched with mould bases 4 is provided with dead head 1 on die cavity 2; Described dead head 1 is located at the middle part of die cavity 2, is respectively equipped with venthole 3 in the both sides of dead head 1; Described die cavity 2 is made of several layers, is provided with back-up coat therebetween.The network structure that described reinforcing series of strata are worked out by some steel wires.The opening of dead head 1 is made as horn-like, and described venthole 3 is provided with blast pipe.Described mould bases 4 both sides be respectively equipped with can be matched with column through hole 5, on through hole 5, be provided with guide way 6.Described back-up coat is located between the 5th layer and the 6th layer of model chamber 2; Be symmetrically arranged with two ventholes 3 on the die cavity 2, and be positioned at the top of die cavity 2.
