Problems solved by technology

The sprue basin is the throat part of the entire pouring process, and its quality has an important impact on the quality of the casting. For traditional production methods, the sprue basin is mostly conical or basin-shaped, which is prone to siphon effect, resulting in curling Air-entrainment slag defects, resulting in slag inclusion pores in castings

Embodiment 1

[0029] An anti-siphon sprue basin, such as Figure 1-Figure 3 , including the sprue basin sand box 1, the sprue basin metal liquid holding room 6, the gate plug 11, the sprue socket 4 and the anti-siphon dam 3.

[0030] The outermost layer of the anti-siphon sprue pot is the sprue pot sand box 1, the sprue pot sand box 1 is a hollow box body, and a sprue pot metal liquid accommodating chamber 6 is formed in the pot, and the bottom of the sprue pot sand box 1 is provided with There is a sprue socket 4 and an anti-siphon dam 3 is connected to the upper part.

[0031] Further, the sprue pot flask 1 is made by casting, and hangers are designed on the left and right outer walls of the sprue pot flask 1 .

[0032] Further, the anti-siphon dam is made of refractory materials, and its size is: the height is 1.5 times the diameter of the sprue; the width is 1.0 times the diameter of the sprue, and the thickness is 0.5 times the diameter of the sprue .

[0033] Further, the sprue soc...

Embodiment 2

[0035] A method for making an anti-siphon sprue basin, comprising the following steps:

[0036] The anti-siphon sprue basin mould 5 is pre-designed, the shape of the anti-siphon sprue basin mould 5 is the same as the shape of the sprue basin accommodating chamber 6, and the siphon dam positioning hole 7 is reserved on the mould for placing the refractory dam forming the anti-siphon dam 3 material, and leave a 2mm gap at the 7 position of the siphon dam positioning hole to facilitate the placement of the refractory anti-siphon dam refractory material;

[0037] After making the designed mold, place the sprue pot mold 5 in a suitable position in the sand box, and place the sprue nest refractory porcelain tank and the refractory anti-siphon dam.

[0038] Fill the mixed resin sand 2 into the gap between the sand box and the mold, and keep vibrating to ensure the filling density;

[0039] After the resin is hardened, the sprue pot sand box formed by the sand box and the resin sand ...

Embodiment 3

[0042] An anti-siphon sprue basin, its use method is as follows:

[0043] When casting castings, lead the sprue 10 to the upper box surface, and fully tighten it to ensure the strength of the molding sand;

[0044] When closing the box, place a circle of refractory mud along the sprue on the upper surface of the mold, and then place the sprue basin to ensure that the center of the sprue nest 4 of the sprue basin is aligned with the center of the sprue, and then place the sprue nest in the sprue nest. Place the gate plug 11 in 4 and seal it so that the molten metal cannot enter the mold in advance;

[0045] When pouring, start pouring after the casting liquid is smelted qualified. After pouring to more than 2 / 3 of the nozzle basin, pull out the gate plug 11, and the molten metal enters the cavity through the sprue to complete the casting of the casting.

Abstract

The invention relates to a sprue basin, provides an anti-siphon sprue basin and its manufacture and use, which overcomes the problems of quality defects such as slag inclusion and pores in castings that are easily attracted by the sprue basin. Mouth basin sand box, gate plug, sprue basin metal liquid holding room, sprue socket and anti-siphon dam; the outermost layer of the anti-siphon sprue basin is the sprue basin sand box, and the sprue basin metal liquid is arranged inside In the accommodating room, the bottom of the sprue pot sand box is provided with a sprue socket, and an anti-siphon dam is connected to the sprue socket. The anti-siphon sprue basin realizes no siphon phenomenon during the pouring process of the sprue basin, prevents the generation of vortices, reduces the slag inclusion and air entrainment of the product, reduces the defect of slag inclusion pores, and reduces the entrainment of air, scum, and molten slag into the cavity. Conducive to the guarantee of molten iron quality and improve the product quality of castings. Meanwhile, the manufacturing method is simple, reliable and effective, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a sprue basin, in particular to an anti-siphon sprue basin and a method of making and using the same. Background technique [0002] The sprue basin is a container connected to the top of the sprue to receive and introduce molten metal, so that the molten metal can reach a suitable pouring speed and then flow into the sprue. The sprue basin is the throat of the whole pouring process. Its quality has an important influence on the quality of the casting. For the traditional production method, the sprue basin is mostly conical or water basin shape, which is prone to siphon effect, resulting in curling. Air-entrained slag defects, resulting in slag inclusion porosity defects in castings. SUMMARY OF THE INVENTION [0003] The invention overcomes the quality defects such as slag inclusions and pores in the castings that are easily attracted by the sprue basin, provides an anti-siphon sprue basin and a method for making and using it...
