A droplet jet sand casting device capable of uniform mixing of raw materials

Abstract

The invention discloses a droplet jet sand casting device capable of uniformly mixing raw materials, comprising a base, an upper template, a hydraulic rod, an extrusion screw, a first motor, a conduit, a connecting rod, a second motor and a threaded rod. The top of the base is movably installed with a lower formwork, and the upper surface of the lower formwork is fitted with an upper formwork, and the upper surface of the upper formwork is fixedly connected to the fixing frame, and the bottom surface of the fixing frame is fixedly connected to the upper end of the hydraulic rod, while the lower end of the hydraulic rod is fixed. Installed on the base, the top of the upper template is fixedly connected with a spray cylinder. The micro-drop jet sand casting device that can mix raw materials uniformly is equipped with a raw material stirring device inside to fully mix the raw materials, and can automatically add the mixed raw materials to the mold, and the device has a faster raw material addition speed , which improves work efficiency and can exert greater pressure on the 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.
