Patent document No. CN 215436889U discloses an exhaust water sleeve, which includes a sleeve main body, wherein a hollow cooling cavity is arranged inside the sleeve main body, and a cooling water connection pipe is further arranged on the sleeve main body and connected with an external cooling seawater pipe; and a butt joint pipe is also arranged on the end surface of one side of the sleeve main body and is in butt joint conduction with the main engine exhaust main pipe. The utility model discloses a can cool off the diesel engine exhaust combustion gas, reduce the destruction to hull plate paint and cabin insulating material. However, the utility model cannot solve the above technical problems.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a to the not enough of prior art, the carminative foundry goods structure of a solution water jacket pipe inner chamber that provides can in time discharge the die cavity gas, and the foundry goods pipe wall is smooth, pore-free, and the drawing of patterns is convenient moreover.

In order to solve the technical problem, the utility model discloses the technical scheme who takes is:

the utility model provides a solve carminative foundry goods structure of water jacket pipe inner chamber, includes the water jacket pipe foundry goods, the water jacket pipe foundry goods has two inner chambers on exhaust layer and water jacket layer, the water jacket pipe foundry goods left and right sides all is equipped with the exhaust flange, water jacket pipe foundry goods upside sets up an exhaust flange, and the downside sets up two exhaust flanges, and the exhaust flange of upside is located between two exhaust flanges of downside.

Furthermore, the two casting structures are provided with a static pressure line outer mold, the two casting structures are vertically placed, and a top riser exhausts air.

Further, the outer mold of the casting structure has three top risers.

Furthermore, three exhaust flanges on the upper side and the lower side of the water sleeve casting are communicated with an exhaust layer.

Further, the two exhaust flanges on the left and right sides are symmetrical to each other.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model provides an exhaust foundry goods structure of water jacket pipe inner chamber, on the basis that the water jacket pipe left and right sides is equipped with the exhaust flange, add three exhaust flange, the upside is one, the downside is two, forms spatial distribution with two original to make the die cavity that can in time discharge in a large amount of gases that the psammitolite that forms the water jacket layer produced at the in-process of pouring, avoid the foundry goods pipe wall too many gas pockets to appear, and the unqualified problem of wall thickness.

Additionally, the utility model discloses a casting mode of "two pieces of one mould", same static pressure line external mold is joined in marriage to two foundry goods structures, and two foundry goods structures are vertical to be placed, and the top rising head is carminative, and not only production efficiency is high, and the foundry goods pipe wall is smooth moreover, and the pore-free, the yield is high.

Detailed Description

In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention will be combined below to clearly and completely describe the technical solution of the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments, which can be derived from the description of the embodiments of the present invention by a person skilled in the art, are within the scope of the present invention.

As shown in figures 1-2, the left side and the right side of a water sleeve casting before improvement are provided with exhaust flanges, so that the problem of air holes of a water sleeve layer exists.

Comparative example 1

As shown in figure 3, a mode of 'one mould with two parts' is adopted, two castings are horizontally placed, and through multiple experiments, the problem of air holes of a water jacket layer cannot be solved by adjusting fire inlet and riser and increasing exhaust.

Comparative example 2

As shown in figure 4, the 'one-die-one-piece' mode is adopted, and a casting is vertically placed, so that the problem of air holes of a water jacket layer can be solved, but the process operation is too complex, batch production cannot be realized, the cold shut problem exists, and the yield is low.
