Pattern drawing mechanism for founding moulding and founding moulding machine using the pattern drawing mechanism

Abstract

A pattern drawing mechanism for founding moulding is characterized in that the mechanism comprises a pedestal, columns, a sand mould, a sandbox, and a pattern drawing bracket; a workbench plate is disposed at the upper end of the pedestal, the two columns are disposed at the back side part of the pedestal vertically with an interval; the pattern drawing bracket comprises two branch brackets facing to each other; each branch bracket is bended, and a central part is connected to the respective column and is rotatable; both front end parts have a support bar respectively, and back end parts are connected to a sliding member together; correspondingly, a guiding member is transversely extended out from the back end part of the pedestal; and the sliding member is disposed on the guiding member and is capable to move back and forth. The invention also discloses a founding moulding machine using the pattern drawing mechanism. Compared with the prior art, the pattern drawing mechanism of the invention has the advantages of convenient and fast operation, reduced labor intensity, no displacement or deformation of the sand mould, and can guarantee the precision of subsequent casting products.

Description

technical field [0001] The invention relates to a die-cutting mechanism, and also relates to a sand-turning molding machine applied with the die-cutting mechanism. Background technique [0002] Sand casting is widely used in the casting of metal products. First, a sand mold with an inner cavity consistent with the product is produced by a sand molding machine, and then the heated metal melt is poured into the sand mold through the pouring port. After cooling, it solidifies to obtain the desired result. The molding sand is generally made of quartz sand with strong refractoriness. When molding sand into a sand mold, it needs to be compacted, so that the density of each part of the sand mold will be uniform, and the quality of the obtained casting products can be guaranteed. The traditional compaction is achieved by manual beating, which is laborious and inefficient. Later, there is a mechanical compaction mechanism. Although labor is freed, the compaction effect is not ideal. ...

AI Technical Summary

Problems solved by technology

Traditional compaction is achieved by manual beating, which is laborious and inefficient. Later, a mechanical compaction mechanism was introduced. Although the labor force was liberated, the compaction effect was not ideal. When compacting, it is generally compacted from top to bottom. Here There is a shortcoming that the upper molding sand is compacted, while the lower one is relatively loose. There is unevenness in the upper and lower parts, and the quality of the casting product is still difficult to guarantee. At the same time, mechanical compaction has a relatively large impact on the overall molding machine, which is easy to cause damaged, thereby reducing the useful life

In addition, in the traditional molding of the sand box, the transfer of the sand box requires manual operation, the labor intensity of the workers is high, and it is easy to damage the formed shape
