Problems solved by technology

Although a great improvement has been made in preventing damage to the target part model, due to the carelessness of the staff or the slight impact of the outside world, the core support will tilt or fall, and the support is not firm, which will also cause damage to the target part model

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. As shown in the figure, the elastic support includes the upper stay 3 and the lower stay 2, and the connecting piece connecting the upper stay 3 and the lower stay 2. The material used for the upper stay 3 and the lower stay 2 is the same as that of the casting , its melting point is slightly higher than the melting point of the casting metal to ensure that it has enough strength to support the sand core before the casting is completely solidified, and at the same time it is well fused with the casting during the solidification process, and the surface is clean, oil-free, rust-free, and Moisture, preferably galvanized or tinned, must be pickled strictly before electroplating. The connecting piece includes an upper link 5 and a lower link 4, the upper link 5 is connected to the upper brace 3, the lower link 4 is connected to the lower brace 2, the upper li...

Abstract

The invention relates to an elastic core support for fixing a sand core, and belongs to the technical field of casting. The elastic core support comprises an upper supporting sheet, a lower supporting sheet, and a connecting part for connecting the upper supporting sheet and the lower supporting sheet. The elastic core support is characterized in that the connecting part comprises an upper connecting rod and a lower connecting rod; the upper connecting rod is connected to the upper supporting sheet, and the lower connecting rod is connected to the lower supporting sheet; the upper connecting rod and the lower connecting rod are connected through an elastic block; an extending block is arranged on the upper supporting sheet. The elastic core support has the beneficial effects that the problems that the core support inclines or topples and falls and is not firm in supporting are solved, the problems such as core breaking and core deviating of the product of such type can be solved, so that the rate of finished products can be increased; the product production efficiency is improved, and the production cost is reduced. Therefore, the market competitiveness of the product is improved.

Description

technical field [0001] The invention relates to an elastic core support for fixing a sand core, which belongs to the technical field of casting. Background technique [0002] At present, it is a common practice to use special shaped supports, ie core supports, to assist sand cores in casting technology. The shape of the core support is various, such as flat, arc-shaped, U-shaped, etc., and the size and length are different. The core support should be selected according to the position of the core support in the casting, the shape of the cavity, and the wall thickness of the casting. shape, size. However, for complex cavity products with multiple cores, multiple compartments, broken chambers, and broken suspension cores, and products with strict requirements on wall thickness, size, and shape and position accuracy, it is necessary to design and manufacture many core supports with different shapes and sizes. The height of some core supports is very different, and the require...
