Droplet jetting type sand mold casting device capable of uniformly mixing raw materials

Abstract

The invention discloses a droplet jetting type sand mold casting device capable of uniformly mixing raw materials. The droplet jetting type sand mold casting device comprises a base, an upper mold plate, a hydraulic rod, an extrusion screw rod, a first motor, a guide pipe, a connecting rod, a second motor and a threaded rod, the top of the base is movably provided with a lower mold plate, and the upper surface of the lower mold plate is attached to the upper mold plate; and the upper surface of the upper die plate is fixedly connected with a fixing frame, the bottom face of the fixing frame is fixedly connected with the upper end of a hydraulic rod, the lower end of the hydraulic rod is fixedly installed on a base, and the top of the upper mold plate is fixedly connected with a spraying cylinder. According to the micro-droplet jetting type sand mold casting device capable of uniformly mixing the raw materials, a raw material stirring device is arranged in the micro-droplet jetting type sand mold casting device, so that the raw materials are fully mixed, the mixed raw materials can be automatically added into a mold, the device has a higher raw material adding speed, the working efficiency is improved, and meanwhile, higher pressure can be applied to a raw material body.

Description

technical field [0001] The invention relates to the technical field of sand casting, in particular to a droplet jet sand casting device capable of uniformly mixing raw materials. Background technique [0002] Sand casting is a method of manufacturing products. Pour fluid raw materials into molds, and after certain processing steps, the raw materials are solidified and formed. Sand molds are mainly composed of siliceous sand and binders. Sand molds are cheap and high temperature resistance. [0003] Yet existing sand casting device has the following problems: [0004] 1. There is no stirring structure inside the device. When the operator pours the raw materials, the raw materials are not fully mixed, which will affect the product quality, and even defective products will appear, resulting in waste of raw materials and increased production costs; [0005] 2. The sand casting device on the market only uses the gravity of the raw material itself to make the raw material flow i...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to provide a droplet jet sand casting device that can evenly mix raw materials, to solve the above background technology, it is proposed that there is no stirring structure inside the device, and when the operator pours the raw materials, the raw materials are not fully mixed. It will affect the product quality. The sand casting devices on the market only use the gravity of the raw materials to make the raw materials flow into the mold. The speed of adding raw materials is slow, which reduces the production efficiency, and the pressure on the raw materials is relatively small.
