Electric sand screening machine applied to sand mold casting

Abstract

The invention discloses an electric sand screening machine applied to sand mold casting. The electric sand screening machine comprises a frame; the top of the frame is respectively fixedly connected with the lower edges of the two sides of a first screening box; the internal surface of the first screening box is provided with two fixers; the fixers can be matched and connected with a second screening box in a matching manner; the bottom of each fixer is fixedly connected with the surface of the first screening box in a welding manner; each fixer comprises a shell and a fixing button; the top of the inner wall of each shell is fixedly connected with the top of a fixing part; and the bottom of each fixing part is fixedly connected with the upper surface of a sliding rod. According to the electric sand screening machine for sand mold casting, the sliding rods are movably connected with a first sliding sleeve and a second sliding sleeve, and the fixing buttons and returning rods are matched in use so that an effect of displacement of the returning rods is achieved; by an elastic deformation theory of a reset spring and by match usage of a fixing block and an L-shaped clamping groove which is formed in the shell of the second screening box, the effect of fixing the second screening box is achieved; the fixers and the second screening box are clamped, so dismounting can be implemented at any time.

Description

technical field [0001] The invention relates to the technical field of mechanical disassembly and assembly, in particular to an electric sand screening machine for sand casting. Background technique [0002] The electric vibrating sieve works by using the reciprocating vibration generated by the vibrating equipment to classify the volume of the objects. The small particles are screened out by vibration, and the large particles are left in the original sieve, thus helping people to separate quickly. out the required objects. [0003] Nowadays, when the existing electric vibrating screens for sand casting cannot be poured out due to the stuck sand particles, or because the internal parts are damaged, when the existing electric vibrating screens are working, it is often necessary to disassemble each part of the vibrating screen for maintenance or This not only wastes time, but also has low work efficiency and brings troubles to people.

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an electric sand screening machine for sand casting, which solves the problem that the existing electric vibrating screen for sand casting cannot be poured out due to sand stuck, or because internal parts are damaged. When it is unable to work, it is often necessary to disassemble each part of the vibrating screen for maintenance or processing, which not only wastes time but also reduces work efficiency.
