Abstract
The utility model discloses a kind of exhaust radiating core frame of large tube-like foundry goods, solve the problem of easy displacement and poor radiation in core box that existing core frame exists.Comprise core frame cylindrical shell (1), the lower end of core frame cylindrical shell (1) is provided with lower flange (2), the upper end of core frame cylindrical shell (1) is provided with upper flange plate (3), core frame cylindrical shell (1) is provided with exhaust heat radiation round (4) at equal intervals radian, core frame cylindrical shell (1) is also provided with anti-rotation at equal intervals radian and erects gusset (5).The utility model makes the core of large tube-like foundry goods be provided with enough intensity, and has good exhaust heat sinking function, ensure that the castability of product.
Description
Technical field
The utility model relates to a kind of casting frock, the core frame particularly in a kind of core box used when casting barrel structure castings.
Background technology
Existing large tube-like foundry goods has been cast by pressure reduction in pressure reduction casting machine, beats in core process in casting, will place core frame in the middle of core box, for improving the intensity of core, and plays the effect of exhaust and heat radiation simultaneously.Existing core frame is a cylindrical body, easily be moved beating in core back-up sand process, have influence on the quality of core, because core frame cylindrical shell is closed cylinder, the gas produced during casting and heat are easily gathered in core and cannot shed, and easily cause foundry goods to produce the casting flaw such as pore, shrinkage porosite.
Summary of the invention
The utility model provides a kind of exhaust radiating core frame of large tube-like foundry goods, solves the technical problem of easy displacement and poor radiation in core box that existing core frame exists.
The utility model solves above technical problem by the following technical programs:
A kind of exhaust radiating core frame of large tube-like foundry goods, comprise core frame cylindrical shell, the lower end of core frame cylindrical shell is provided with lower flange, the upper end of core frame cylindrical shell is provided with upper flange plate, core frame cylindrical shell is provided with exhaust heat radiation round at equal intervals radian, core frame cylindrical shell is also provided with anti-rotation at equal intervals radian and erects gusset.
The anti-rotation that core frame cylindrical shell is arranged at equal intervals radian erects gusset six pieces, erects on gusset be provided with lightening hole in anti-rotation.
The utility model makes the core of large tube-like foundry goods be provided with enough intensity, and has good exhaust heat sinking function, ensure that the castability of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail:
A kind of exhaust radiating core frame of large tube-like foundry goods, comprise core frame cylindrical shell 1, the lower end of core frame cylindrical shell 1 is provided with lower flange 2, the upper end of core frame cylindrical shell 1 is provided with upper flange plate 3, core frame cylindrical shell 1 is provided with exhaust heat radiation round 4 at equal intervals radian, core frame cylindrical shell 1 is also provided with anti-rotation at equal intervals radian and erects gusset 5.
The anti-rotation that core frame cylindrical shell 1 is arranged at equal intervals radian erects gusset 5 six pieces, erects on gusset 5 be provided with lightening hole 6 in anti-rotation.
This core frame, by erecting gusset 5 in cylindrical shell arranged outside anti-rotation, makes core frame good location in sand not be moved, ensure that the Forming Quality of core.Make the gas in core and heat enter into cylindrical shell by louvre by arranging exhaust louvre on cylindrical shell and discharge, ensure that the castability of foundry goods.
