Novel casting mold and molding method thereof

Abstract

The invention discloses a novel casting mold and a molding method thereof. The casting mold consists of a rotary disk (1), a base plate (2), a fixed scraping plate (3), a steel outer mold (4), steel upper mold (5), fixed shafts (6), (7) and (9) and a bracket (8). The molding method comprises the following steps of: placing a prefabricated two-sheet mold sample onto the edge of the base plate (2); matching the steel outer mold (4) and fastening; filling sand into the steel outer mold (4) and ramming; striking off a top surface with the scraping plate when the sand reaches the top surface; putting a top plate mold sample; matching the steel upper mold (5); filling sand into the steel upper mold (5) and ramming; leaving a sprue gate and an air outlet hole; opening the steel upper mold (5) and the steel outer mold (4); taking the mold sample out; and starting casting. When a second casting is required to be cast, the method comprises the following steps of: enclosing the two-sheet mold sample; filling sand into the cavity of the two-sheet mold sample; ramming; taking the mold sample away; scraping a mold cavity by rotating the rotary disk (1) and using the fixed scraping plate (3); and matching the steel outer mold (4) and the steel upper mold (5) to cast. The novel casting mold has the advantages of saved labor force, low labor intensity, high success rate, high accuracy, easiness for demolding, short flow, low time consumption and high efficiency, and is particularly suitable for casting container castings such as copper drums, boilers, basins and the like.

Description

Technical field [0001] The present invention relates to a casting mold, more specifically, the present invention relates to a novel casting mold and its modeling method Background technique [0002] At present, sand box modeling is mostly used in metal casting. The general production process is to place the pattern and the sand box, fill and scour the sand, trim and reshape, trim the parting surface, place the sand box, fill and scour the sand, trim and open the mold, trim the parting surface, and start the mold. And trim the sand mold to fit the mold. It can be seen from the above production process that it has the following shortcomings: first, the process is lengthy and complicated, which takes up a lot of time; second, the use of two upper and lower sand boxes to manually mold the core, which is labor-intensive; third, the continuous turning of the box during the process, The mold and the core are easily damaged; fourth, the molding sand around the pattern must be loosened ...

AI Technical Summary

Problems solved by technology

It can be seen from the above production process that it has the following defects: first, the process is lengthy and complicated, which takes up a lot of time; second, the upper and lower sand boxes are used to manually shape the core, which is labor-intensive; The mold core is easy to be damaged; the fourth is to loosen the molding sand around the pattern when the mold is opened, the core is easy to deform, and the core size and surface pattern are easy to lose shape, and it is difficult to form a precise casting after casting

So far, there is no better solution
