The invention discloses an improved sprue sleeve of a low-pressure casting mold, which comprises a sprue sleeve main body, a bump, an insulating material, a square fixing block, and a pouring channel, and is characterized in that: the sprue sleeve main body is fixed on the The middle part of the fixed structure, the top of the main body of the sprue sleeve is connected with the sprue of the bottom mold through the protrusion, the middle part of the main body of the sprue sleeve is left with a pouring channel structure, and the middle and top of the pouring channel are equipped with ceramic filters. The outer side of the pouring channel is filled with thermal insulation material, the bottom of the pouring channel is provided with a rectangular concave block structure for connecting with the liquid riser, and the ceramic filter is provided with mesh holes. The improved sprue sleeve of low-pressure casting mold has good heat preservation effect, and is simple to manufacture, reduces the cost of the sprue sleeve, can filter the inclusion and slag inclusion of molten metal, and improves the qualification rate of the casting body. The sprue sleeve has a reasonable design, The cost is low, and it is suitable for extensive popularization and use.
Description
technical field [0001] The invention relates to the technical field of low-pressure casting, in particular to an improved sprue sleeve of a low-pressure casting mold. Background technique [0002] Sprue sleeves have been widely used in low-pressure die-casting molds, which can protect the mold very well, but most of the sprue sleeves are of ordinary structure, made of simple metal alloys, with poor heat preservation effect, and some have heating structures on the outside , not only increases the cost, but also the insulation effect is not very ideal, and few sprue sleeves are equipped with leak-proof structure and filter structure. Contents of the invention [0003] The purpose of the present invention is to provide an improved low pressure casting mold sprue bushing to solve the problems raised in the above background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: an improved sprue bushing for ...
