Abstract

The utility model relates to a gas lead-out and heat dissipation device for a bun core below a large riser of cast steel. A T-shaped mud core is pressed on the bun core below the large riser of the cast, and the exhaust channel of the T-shaped mud core is communicated with the bun core through a steel pipe. Through using the mud core to lead out gas in the bun core, not only the exhaustion of the mud core is improved, but also the heat dissipation effect is enhanced. So that the shortcoming of the bun core of poor exhaustion is overcome, and the pore generation rate and shrinkage porosity rate of castings are lowered to ensure the internal quality of the castings.

Description

Steamed bun core bleed heat abstractor under the big rising head of cast steel

Technical field

The utility model belongs to casting technology field, relates to a kind of loam core that utilizes the gas of steamed bun in-core is drawn, and can improve the exhaust of steamed bun core, can strengthen steamed bun core bleed heat abstractor under the big rising head of cast steel of radiating effect again.

Background technology

The all gas that in casting process, is produced all is that the steamed bun core periphery under the avoiding greatly of casting quality, particularly rising head is surrounded by molten steel, is unfavorable for heat radiation and exhaust.The traditional exhaust method is to lean on the core print base bleed, and such shortcoming is the long-time high temperature of foundry goods, and the difficult discharge of gas, is prone to produce pore or shrinkage porosite, makes foundry goods have very big hidden danger of quality.

The utility model content

In order to overcome the above-mentioned shortcoming of prior art ,It is a kind of that the utility model provides, and utilizes the loam core that the gas of steamed bun in-core is drawn, and can improve the exhaust of steamed bun core, can strengthen steamed bun core bleed heat abstractor under the big rising head of cast steel of radiating effect again.

The utility model solves the technical scheme that its technical problem adopted: steamed bun core bleed heat abstractor under the big rising head of a kind of cast steel; On the steamed bun core under the big rising head of foundry goods, be pressed with " T " font loam core, the exhaust passage in " T " font loam core is connected with the steamed bun core through steel pipe.

The head of said steamed bun core is the plane.

The bore of said " T " font loam core both upper ends thereof is greater than the rising head diameter.

The periphery of said steel pipe is established the hole and is connected with the steamed bun core.

The beneficial effect of the utility model is: utilize the loam core that the gas of steamed bun in-core is drawn; The exhaust of steamed bun core can be improved, radiating effect can be strengthened again; Thereby changed the bad shortcoming of steamed bun core exhaust, reduced the probability of foundry goods generation pore or shrinkage porosite, guaranteed the inherent quality of foundry goods.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Among the figure: 1-foundry goods, 2-subsidy, the big rising head of 3-, 4-" T " font loam core, 5-steamed bun core, 6-steel pipe.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Referring to Fig. 1; Steamed bun core bleed heat abstractor under the big rising head of a kind of cast steel is cooked steamed bun core 5 heads under the foundry goods 1 big rising head 3 flat, " T " font loam core 4 is pressed on the flat steamed bun core 5 again; The bore of " T " font loam core 4 both upper ends thereof is greater than the diameter of big rising head 3; Under the situation that does not influence big rising head 3 feeding, steamed bun core 5 is connected with steamed bun core 5 through steel pipe 6 peripheral pores with the exhaust passage in " T " font loam core 4, and then draws exhaust from big rising head 3 both sides; Thereby solved the 5 bad exhausts of steamed bun core, long-time high temperature, be prone to produce pore or shrinkage porosite casting flaw.

Claims

1. steamed bun core bleed heat abstractor under the big rising head of cast steel, it is characterized in that: on the steamed bun core under the big rising head of foundry goods, be pressed with " T " font loam core, the exhaust passage in " T " font loam core is connected with the steamed bun core through steel pipe.

2. steamed bun core bleed heat abstractor under the big rising head of cast steel as claimed in claim 1, it is characterized in that: the head of said steamed bun core is the plane.
