Description

Heightening mechanism for casting sand box

Technical Field

The utility model relates to a bed hedgehopping mechanism specifically is a bed hedgehopping mechanism for casting sand box.

Background

For a casting with a large plane facing downward during casting, a bottom pouring type gating system is generally adopted in order to prevent defects such as cold shut, iron beans and the like, and ingates are uniformly overlapped by using casting paper tubes or ceramic tubes. Because the ingate is far lapped, the material yield is relatively low, and simultaneously, the cost of raw and auxiliary materials is increased, thereby being not beneficial to energy conservation and consumption reduction. In order to solve the problem, an inclined pouring mode is usually adopted, one side of the bottom of a sand box is raised by a chilling block or a wood block, and when a casting is in a pouring position, a large plane of the casting forms a certain angle with a horizontal plane. Meanwhile, the inner pouring gate is designed to enter water from the lower position of the casting, the scheme can reduce the lap joint of the cast paper tube and the ceramic tube, improve the yield of molten iron products, and reduce the cost of auxiliary materials and labor hour.

In addition, the sand box is necessary technical equipment in the casting industry, and the space of a workshop is limited, so that the specification and the number of the sand box are generally required not to be too much on the premise of meeting the production requirement of casting products. In order to solve the problem, when the heights of different sand boxes are not greatly different, a method of padding the bottom of the sand box by using a chill or a wood block is also adopted. When the height of the sand box is not enough, the periphery of the sand box can be padded up through the chill or the wood block, which is equivalent to the height of one cushion block added to the whole sand box.

The method for lifting by using the chilling blocks or the wood blocks has certain safety risk and is inconvenient to use.
