Abstract
The utility model relates to the field of smelting technology, relates to a casting mould, and in particular relates to a negative-pressure casting mould box. The box comprises a casting mould box body, and is characterized in that the casting mould box body is provided with a cover body; the contact parts of the cover body and the casting mould box body are combined with each other in a sealing way; the cover body is provided with a water inlet; and the casting mould box body is provided with a vacuum pumping tube. Therefore, the negative pressure casting mould box with the structure has the advantages of improving product quality, and ensuring that internal structures of products are more compact and internal bubbles of the products are few.
Description
Technical field
The utility model relates to technical field of smelting, relates to casting mould, particularly a kind of negative pressure mold case.
Background technology
In the prior art, the mould of casting is to carry out in the situation of atmosphere, that is to say that the air pressure in the die box is atmospheric pressure, the product of making like this have organize not fine and closely woven, the pore phenomenon arranged, have shortcoming of low quality.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provides a kind of and can improve the quality of products, interiors of products organizes the negative pressure mold case tighter, that the interiors of products bubble is few.
The technical solution of the utility model is achieved in that a kind of negative pressure mold case, comprise mold case body, it is characterized in that: described mold case body has lid, lid and the sealing combination of mold case body contact position, described lid has water inlet, and described mold case body has vacuum-pumping tube.
The beneficial effects of the utility model are: the negative pressure mold case of this spline structure have can improve the quality of products, interiors of products organizes advantage tighter, that the interiors of products bubble is few.
Description of drawings
Fig. 1 is the structural representation of a kind of negative pressure mold of the utility model case.
Wherein: 1, mold case body 2, lid 3, water inlet 4, vacuum-pumping tube.
Specific embodiments:
Below in conjunction with accompanying drawing the utility model is further described.
As described in Figure 1, a kind of negative pressure mold case comprises mold case body 1, it is characterized in that: described mold case body 1 has lid 2, lid 2 and the sealing combination of mold case body 1 contact position, described lid 2 has water inlet 3, and described mold case body 1 has vacuum-pumping tube 4.
