Embodiment Construction

[0009] Such as figure 1 As shown, the present invention supports and connects an upper fixing plate 3 above the sand pressing plate 1 through a plurality of connecting columns 2, and a circular mold avoidance hole 4 is respectively provided at the middle of the upper fixing plate 3 and the sand pressing plate 1, so that The above-mentioned fixed plate 3 corresponds to the circular mold avoidance hole 4 on the sand pressing plate 1 . Through the above settings, the upper fixing plate 3 of the present invention is connected with the upper pressing plate of the casting sand molding machine, the sand pressing plate 1 can compact the various parts of the sand mold of the brake hub, and the sand mold can enter the circular mold avoidance hole 4, The collision between the sand mold and the sand press plate 1 is avoided, and the sand press plate 1 keeps pressing down until the sand mold is compacted to ensure the compaction strength.

Abstract

The invention discloses a sand mould compressing frame for a brake hub moulding line, which is characterized in that an upper fixed plate is connected to the upper part of a sand compressing plate through a plurality of connecting posts in a supported manner; round mould avoiding holes are formed in middle parts of the upper fixed plate and the sand compressing plate respectively; the round mould avoiding holes in the upper fixed plate and the sand compressing plate correspond to each other. Through the arrangement, the sand mould compressing frame is mounted on an upper pressure plate of a moulding machine for casting sand moulds, all parts of sand moulds can be compressed, so that the requirements on rigidity of sand moulds can be met, the phenomena of sand expanding, sand removal and box expanding of a casting mould can be avoided, and the yield of cast can be improved.

Description

technical field [0001] The invention relates to a casting device, in particular to a molding sand pressing frame used on a casting sand molding machine. Background technique [0002] In the process of producing molds in the foundry industry, flat plates were originally used for compaction, but the molds were not fully compacted, and the hardness did not meet the requirements, resulting in sand swelling, sand washing, and box expansion in castings. Contents of the invention [0003] The object of the present invention is to provide a molding line molding sand press frame for brake hubs in the casting production process. [0004] In order to achieve the above object, the present invention supports and connects an upper fixing plate through a plurality of connecting columns above the sand pressing plate, and a circular mold-avoiding hole is respectively arranged in the middle of the upper fixing plate and the sand pressing plate, and the upper fixing plate Corresponding to t...
