Example Embodiment

[0038] Example one:

[0039] Such as figure 2 As shown, the pouring system of the frame includes a first sprue 2, a first runner 3, two second sprues 4, two second runners 5, multiple filter units 6, multiple Inner runner 7, the first sprue 2 is connected to the upper part of the first runner 3, the lower part of the first runner 3 is connected to the two second sprues 4, and the second sprue 4 is connected to the first runner The upper part of the two runners 5 are connected, and each second runner 5 is provided with a filter unit 6 connected to it. The inner runner 7 is connected with the filter unit 6; when pouring, the exhaust side of the frame faces towards Bottom, the operating side faces upwards, the gating system is introduced from the oil pan from one side, and the molten iron enters from the bottom of the cavity of the casting frame through the inner runner.

[0040] Wherein, the upper part of the first sprue 2 is also provided with a sprue cup, the bottom of which is co...

Example Embodiment

[0041] Embodiment two:

[0042] Such as image 3 As shown, the filter unit 6 in this embodiment includes a filter cavity 61. The filter cavity 61 is arranged in an inverted trapezoidal structure, which has the function of gathering and collecting. The filter plate 62 is fixed transversely to the large end of the filter cavity 61 for filtering The pouring liquid of the second runner 5, the filter 61 is a ceramic foam filter, and the ceramic foam filter can be selected from different refractory materials such as silicon carbide, corundum, etc., and specifications. In this embodiment, a square structure is adopted. In addition, two adjacent filter cavities 61 share a filter sheet 62, or separate filter sheets may be used respectively.

[0043] Wherein, the number of the filtering unit 6 is the same as that of the inner runner 7 to ensure that the pouring liquid is filtered.

[0044] In this embodiment, there are two second runners 5, and there are 16 filter units. Each runner 5 is conn...

Abstract

The invention provides a casting system for a frame. The casting system comprises a first sprue, a first runner, one or more second sprues, one or more second runners, a plurality of filtering units and a plurality of ingates, wherein the first sprue communicates with the upper part of the first runner; the lower part of the first runner communicates with the one or more second sprues; the secondsprues communicate with the upper parts of the second runners; the filtering units communicating with the corresponding second runners are arranged at the lower parts of the corresponding second runners; and the ingates communicate with the filtering units. The invention also discloses a casting method for the frame. A horizontal moulding and pouring process is adopted, an exhaust side surface faces downwards, an operation side faces upwards, the casting system is introduced from a single side of an oil sump side, and molten iron enters from the bottom to realize a pure bottom casting type casting way. The casting system and the casting method have the beneficial effects that the operation is simple, the yield is high, and the stability is high; and defects of shrinkage porosity, air holesand slag holes of a frame casting are effectively reduced, the quality loss is reduced, and the fully-qualified rate of the casting is greatly increased.

Description

technical field [0001] The invention relates to a pouring system and method, in particular to a pouring system and method for a frame. Background technique [0002] The frame is one of the most important parts of the marine diesel engine frame. As the installation matrix of almost all parts of the diesel engine, it is often in a state of complex stress and variable load during work. Therefore, for frame castings, good strength, toughness , impact resistance and other mechanical properties are essential, especially for the compactness of the internal matrix structure of the casting; this targeted casting process meets the increasing strengthening degree (PeCm) of the diesel engine frame and mass production requirements. [0003] The original pouring system technology adopts the bridge type to introduce molten metal from the side of the cylinder hole and the claw side of the foot plate respectively. The flow rate of molten iron is reduced by designing a choke channel, and the...
