4D elastic core support

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 support piece, a lower support piece, and a connecting piece used for connecting the upper support piece and the lower support piece. The elastic core support is characterized in that the connecting piece comprises an upper connecting rod and a lower connecting rod; the upper connecting rod is connected with the upper support piece; the lower connecting rod is connected with the lower support piece; the upper connecting rod and the lower connecting rod are connected by an elastic block; and threads are formed in the upper connecting rod. The elastic core support disclosed by the invention has the beneficial effects that the problems of core breaking, core floating and the like of the products are solved, the finished product rate of the products is increased, the producing efficiency of the products is improved, the production cost is reduced, and the market competitiveness of the products 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...

Problems solved by technology

However, for complex cavity products with multiple cores, multiple compartments, broken chambers, and broken suspension cores, as well as 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. Some core supports have great disparity in height, and each core support needs to be measured with mud balls to obtain the required height. The workload is quite large, and it has become a prominent weak link that affects the shape and the efficiency of core setting.
