A new type of vibrating ring casting mold

Abstract

The invention relates to a new type of vibrating ring casting mold, which includes a pressing plate, on which a module is correspondingly arranged, which is divided into an upper module and a lower module, and the lower module is arranged on the oblique inner side of the upper module, and on the pressing plate A sprue cup is provided in the middle of the upper part, and a runner is provided under the sprue cup. On the runners on both sides of the sprue cup on the positive pressure plate, there are horizontal and vertical sprues downward. An upper edge riser is provided under the horizontal and vertical sprues, and an upper inner gate is arranged on the upper edge riser, and the upper inner gate is arranged on the same horizontal line. There is an intermediate runner between the lower modules on the positive pressure plate, and a lower edge riser is provided between the lower modules on the positive pressure plate, and a lower inner gate is arranged on the lower edge riser, and the lower inner gate is arranged on On the same horizontal line, a flow blocking flange is provided on the counter pressure plate corresponding to the connection between the intermediate runner and the lower flange riser. The invention has reasonable structural arrangement, high product quality and high qualified rate.

Description

technical field [0001] The invention relates to a casting mold, in particular to a vibrating ring casting mold. Background technique [0002] Existing molds have relatively large lateral distances, thick castings, large shrinkage, and insufficient feeding is prone to sinking. In the existing vibrating ring, the molten iron of two mold numbers is directly rushed into the mold cavity from top to bottom. In addition, the ingate is very large, and the speed of punching is fast, so a large number of sand holes are prone to occur. In addition, the upper and lower castings are fed with one riser, and the upper row will suffer from insufficient feeding and shrinkage cavities. Contents of the invention [0003] Purpose of the invention: the purpose of the invention is to overcome the deficiencies in the prior art and provide a new vibrating ring mold with reasonable structure arrangement, high product quality and high pass rate. [0004] Technical solution: In order to solve the ...

Problems solved by technology

[0002] Existing molds have a relatively large lateral spacing, thick castings, large shrinkage, and insufficient feeding is prone to sinking

In the existing vibrating ring, the molten iron of the two mold sizes in the lower row is directly rushed into the cavity from top to bottom, and the ingate is very large, and the speed of the punching is slow, and a large number of sand holes are prone to appear.

In addition, the upper and lower castings are fed with one riser, and the upper row will suffer from insufficient feeding and shrinkage cavities.
