Abstract

The invention relates to an investment casting sprue mold with adjustable size, which belongs to the technical field of investment casting sprue mold structure. The invention solves the problem that the existing investment casting sprue mold is an integral structure, and the fixed size cannot be adjusted. The invention includes an upper die, a lower die and a movable block, wherein the size of the upper die and the lower die is fixed, and the movable blocks are of different shapes and sizes. When in use, different movable blocks are combined and installed in different positions, so that the mold can be pressed into three There are different ring runners with different diameters, and the mold also includes a variable height module. By changing the height dimension of the variable height module, the size of the investment casting runner can be changed in the height direction, so that the height of the investment casting runner is also variable. of. The present invention can obtain individual rings each time the ring sprues with different diameters are separately pressed, without manually cutting off the rest of the rings. In addition, the mold also has the advantages of low additional cost, safety, reliability, and durability.

Description

technical field [0001] The invention relates to an investment casting sprue mold with adjustable size, which belongs to the technical field of investment casting sprue mold structure. Background technique [0002] Titanium and titanium alloys have a series of excellent properties, but the manufacturing cost of titanium alloys has always been high. This is because titanium products are generally forged, which is not easy to process, and the machining allowance is large, and the metal utilization rate is low, which limits the use of titanium alloys. application range. The foundry industry is an important branch of the manufacturing industry, and it plays a vital role in many important industries in the development of the national economy, such as aerospace, energy, and chemical industry. With the development of the market economy and the application of new technologies in industry, the structure of castings is becoming more and more complex and large-scale, and the requiremen...
