Shock-resistant type sand mould bearing device

Abstract

The invention discloses a shock-resistant type sand mould bearing device. The bearing device comprises a bearing device body and shock absorption devices; a placing tank is formed in the bottom of theinner surface of the bearing device; a limiting groove is formed in the surface of the placing tank and is symmetrical relative to the central line of the surface; a load bearing plate is further arranged in the bearing device body; limiting blocks are arranged below the load bearing plate and correspond to the limiting groove; the load bearing plate is fixedly connected with the bottom of the inner surface of the bearing device body via buffer springs; a fixing groove is formed in each of two sides of the lower end surface of the bearing device body; the shock absorption devices are arrangedin the fixing grooves; each shock absorption device comprises a connecting pole, an upper fixed plate, a shock absorber and a lower fixed plate; the upper fixed plate is arranged above the lower fixed plate; the shock absorber is arranged between the upper fixed plate and the lower fixed plate; and the connecting pole is fixedly installed on the upper end face of the upper fixed plate and is connected with the fixing groove. Via the arrangement of the shock absorption devices on the bearing device body and buffer assemblies arranged therein, collision- or shock-caused swaying of a sand mouldin the process of model manufacturing is effectively lessen.

Description

technical field [0001] The invention belongs to the technical field of sand mold equipment, and in particular relates to an anti-shock sand mold bearing device. Background technique [0002] Sand casting is a widely used form of casting; as the name suggests, sand is used to create molds, sand casting involves placing a finished part model or wooden model in the sand, then filling the pattern with sand at the weekend and removing the pattern from the box In the future, the sand forms the mold. In order to take out the mold before casting the metal, the mold should be made into two or more parts. During the mold making process, holes and vent holes for pouring metal into the mold must be left to form a pouring system. After the metal liquid is poured into the mold, it is kept for an appropriate time until the metal is solidified. After the parts are taken out, the mold is destroyed, so a new mold must be made for each casting; It is easy to shake, which affects the quality o...
