Problems solved by technology
[0002] The existing furan resin sand automatic line produces castings suitable for mass production and with medium wall thickness. It is a headache to solve the crack problem of thin-walled castings. The general solution is to control the parameters of the molding sand or add light foam fillers to the molding sand. It is easy to cause high scrap rate of sand molds, many pores and sand holes on the surface of castings, high labor intensity for finishing and grinding, long production cycle, high production cost, and extremely unstable casting quality

Embodiment Construction
[0017] The preparation method of furan resin sand boxless molding shell type comprises the following steps:
[0018] First, fix the tire mold 1 and the mold 2 on the template 3, then fix the sand frame 4 on the template 3, hang the assembled model to the molding line, put the riser 9 (the lower box does not put Riser, put in the upper box).
[0019] Next, control the appropriate molding sand parameters, continuously tighten the resin sand between tire mold 1 and mold 2 during the process of placing the resin sand, and after hardening, the box turning machine turns the sand mold and the model 180°, lifts the model, and takes out the tire from the sand mold. Mold 1, mold 2, sand frame 3 and pattern plate 4, put the upper box 7 on the lower box 5 after painting the paint, put the sprue cup 6 to pour molten steel, and the cavity 8 formed by the tire mold 1 does not enter the molten steel .

Abstract
The invention discloses a method for preparing a furan resin sand removable-flask moulding shell mold. The method mainly comprises the following steps of: preparing a mould required by a shell; and preparing the shell by controlling appropriate moulding sand parameters, swabbing the shell mold, performing mould assembling and pouring. The method reduces the labor intensity, the production cycle, and material consumption, and improves the stability of casting quality.
Description
technical field [0001] The invention mainly relates to the field of furan resin sand boxless molding casting, in particular to solving the problem of carbon steel, 4A, 5A, 6A and CK by using shell molding technology. 3 Casting cracks and casting defects of MCuN and other materials reduce the consumption of resin and curing agent and reduce production costs. Background technique [0002] The existing furan resin sand automatic line produces castings suitable for mass production and with medium wall thickness. It is a headache to solve the crack problem of thin-walled castings. The general solution is to control the parameters of the molding sand or add light foam fillers to the molding sand. It is easy to cause a high scrap rate of sand molds, more pores and sand holes on the surface of castings, high labor intensity for finishing and grinding, long production cycle, high production cost, and extremely unstable casting quality.
