Gold mold casting mold of runner/riser cutting mechanism

Abstract

The invention discloses a gold mold casting mold of a runner / riser cutting mechanism. The gold mold casting mold comprises a movable mold and a fixed mold which are oppositely arranged, a sprue, a horizontal runner, a plurality of product cavities and a riser cavity are formed between the movable mold and the fixed mold, an easily broken groove forming part is arranged between the product cavitiesand the riser cavity, and an easily-break sprue is arranged between the product cavities and the horizontal runner, two cutting mechanisms are arranged on the outer side wall of the fixed mold, the two cutting mechanisms are correspondingly opposite to the riser cavity and the horizontal runner, the outer side wall of the fixed mold is provided with a plurality of cutter bar holes which are opposite to each of the riser cavities or the horizontal runners and are in communication with each other, each cutting mechanism comprises a main installing plate, power connecting rods and a plurality ofshearing cutter rods, the power connecting rods and the shearing cutter rods are fixedly connected to the two sides of the main installing plate correspondingly, and each shearing cutter rod is inserted into the corresponding cutter rod hole. The shearing cutter bar of the mold can be used for cutting off the easily-broken sprue and the riser under the action of an external force so as to realizeactive separation of a casting product from the runner and the riser, so that the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a gold mold casting mold with a runner / riser cutting mechanism. Background technique [0002] In the existing cast iron (such as gray cast iron, ductile iron) industry, metal mold (gold mold for short) casting and sand casting are the two most common casting methods, and both methods are suitable for batch production of iron product blanks. Production. However, as the country's control of environmental protection and energy conservation becomes more and more strict, the problems of sand casting, such as large dust, many equipment and high noise, have become particularly prominent. In contrast, the application of metal molds in the foundry industry has once again shown its advantages, such as: there is no procurement and storage of raw materials such as molding sand and bentonite; there is no procurement and maintenance of sand processing equipment; no sand cleaning is required in ...

Problems solved by technology

[0003] However, if figure 1 As shown, in the existing gold mold casting mold, the sprue (including the vertical sprue 3 and the horizontal sprue 4 ), the product 23 and the riser 24 are ejected as a whole when the mold is opened, and it needs to be manually removed after cooling. Sprue and riser 24, so as to obtain independent products 23, so it is necessary to set a specific post to correspond to the cutting work of sprue / riser 24, which not only reduces production efficiency, but also increases production cost
