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, which belongs to the technical field of casting. The elastic support includes an upper brace and a lower brace, and a connecting piece connecting the upper brace and the lower brace, and is characterized in that: the connecting piece includes an upper link and a lower link, and the upper link The upper brace is connected, the lower link is connected with the lower brace, the upper link and the lower link are connected by an elastic block, and an extension block is arranged above the upper brace. The beneficial effects of the present invention are: solve the problem that the core support will be tilted or toppled, and the support is not firm, solve the problems of folded core and floating core of this type of product, improve the yield of this type of product; improve the production rate of the product Efficiency, reduced production costs, and improved market competitiveness of products.

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...
