AI Technical Summary

Technical Problem

In the existing disappearing mold casting technology, quartz sand flows rapidly when the casting is removed, resulting in operator safety threats and casting damage.

Method used

A disappearing mold casting mold is designed, including the first sand box and the second sand box. By setting up structures such as compacting plates, curling edges, reciprocating plates and pressure relief parts, the flow and discharge of quartz sand are controlled to ensure the safety of the castings. Sex and integrity.

Benefits of technology

Effectively slow down the flow rate of quartz sand, ensure the safety of operators, avoid damage to castings, and reduce the steps of laying the sand bottom during repeated casting by reusing sand bottom.

Abstract

The present invention belongs to the technical field of lost foam casting, and specifically discloses a lost foam casting mold, comprising a first sand box, wherein the bottom of the first sand box is fixedly connected to a base, and both sides of the inner wall of the first sand box are provided with evenly distributed second sand outlets, and both sides of the outer wall of the first sand box are slidably connected to closed doors, and the closed doors block the second sand outlets, and both sides of the inner wall of the first sand box are slidably connected to reciprocating plates, and one side of the outer wall of the reciprocating plate is fixedly connected to evenly distributed compacting plates. In the present invention, by arranging structures such as compacting plates and warping edges, the quartz sand inside the first sand box can be shaped and lifted to prevent it from sinking downward quickly after the second sand outlet is opened, and at the same time, it can also block the quartz sand in the middle, limit the flow speed of the quartz sand, facilitate operators to guide and collect it in an orderly manner in a safe environment, and ensure that the casting is not affected by it.
