Casting mold capable of improving casting yield

Abstract

The casting mold capable of improving the casting yield comprises a pressing plate and a base, a casting pressing block is fixedly installed below the pressing plate, a casting groove body is fixedly installed on the base, two sealing cylinders are symmetrically arranged in the base, sealing plates are slidably installed in the two sealing cylinders, and the sealing plates are fixedly installed on the base. And fixing shafts are fixedly connected to the two sealing plates. The casting device has the advantages that a heat conduction block can make contact with a heat conduction piece firstly along with movement of a heat insulation plate, so that a temperature increasing device can fully preheat a casting groove body, and the situation that air holes are formed in the surface or the interior of a casting due to the fact that the contact position of a liquid material and the casting groove body is rapidly cooled is avoided; when the vibration device vibrates, the vibration device is electrified to prevent a gap from being generated between the upper cylinder and the circular groove during vibration, and the upper cylinder is made of an elastic metal material and can amplify vibration, promote gas in a liquid material to be discharged outwards and improve the defoaming effect.

Description

technical field [0001] The invention relates to the technical field of casting processing, in particular to a casting mold capable of improving the yield of castings. Background technique [0002] Most of the existing metal parts are formed by casting, which can not only reduce the production cost, but also process metal parts with complex structures by designing molds, which are less restricted by size and shape, but the scrap rate in the casting process is also high The main reason is that the casting structure is not dense enough, and there are defects such as shrinkage cavities, air pockets, and pores. The pores that only exist on the surface of the casting can be easily detected by visual observation or optical system identification, and are processed by grinding and other means. Improvement, porosity located inside the casting is difficult to detect and repair. [0003] The external factors that form pores inside the casting are mainly due to the low preheating temper...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the prior art, when the liquid material contacts the mold, the temperature of the mold is low, and the gas in the liquid material cannot be discharged during the pouring process, resulting in easy formation of pores inside the casting and the rate of rejects during the casting process. Higher problems, and a casting mold that can improve the yield of castings is proposed
