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 a sprue basin sand box 1, a sprue basin molten metal holding room 6, a gate plug 11, a sprue nest 4 and an anti-siphon dam 3.

[0030] The outermost layer of the anti-siphon sprue basin is a sprue basin sand box 1, and the sprue basin sand box 1 is a hollow box body, and a sprue basin metal liquid storage room 6 is formed in the basin, and the bottom of the sprue basin sand box 1 is arranged There is a sprue nest 4 and an anti-siphon dam 3 connected to the upper part.

[0031] Further, the sprue pot sand box 1 is cast, and hangers are designed on the left and right outer walls of the sprue pot sand box 1 .

[0032] Further, the anti-siphon dam is fired from 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 nest 4 is formed by pl...

Embodiment 2

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

[0036] Pre-design the anti-siphon sprue basin mold 5, the shape of the anti-siphon sprue basin mold 5 is consistent with the shape of the sprue basin accommodation chamber 6, and the siphon dam positioning hole 7 is reserved on the mould, which is used to place the refractory materials, and leave a gap of 2 mm at the siphon dam positioning hole 7, so that the fire-resistant and anti-siphon dam refractory materials can be put in easily;

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

[0038] Fill the mixed resin sand 2 into the gap between the sand box and the mould, and vibrate continuously to ensure the filling density;

[0039] After the resin is hardened, separate the sprue pot sand box formed by the sand box and the resin sand from the mold; then apply a hi...

Embodiment 3

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

[0043] When molding the casting, 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 on the upper surface of the mold along the sprue, and then place the sprue basin to ensure that the center of the sprue pocket 4 of the sprue basin is aligned with the center of the sprue. Place gate plug 11 in 4 and seal so that molten metal cannot enter the mold in advance;

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

Abstract

The invention relates to a pouring basin, and provides an anti-siphon pouring basin, and manufacturing and use thereof. The problems of slag inclusion, pores and other quality defects of castings dueto easy occurrence of siphon of the pouring basin are solved. The anti-siphon pouring basin comprises a pouring basin sand box, a pouring gate plug, a pouring basin molten metal containing chamber, asprue base and an anti-siphon dam; the pouring basin sand box is arranged on the outermost layer of the anti-siphon pouring basin, and the pouring basin molten metal containing chamber is arranged inthe anti-siphon pouring basin; the sprue base is arranged at the bottom of the pouring basin sand box, and the anti-siphon dam is connected to the sprue base. According to the anti-siphon pouring basin, no siphon phenomenon exists in the pouring process of the pouring basin, and vortexes are avoided; the conditions of slag inclusion and gas entrapment of products are reduced and the defects of slag inclusion and pores are reduced; gas entrapment, dross and molten slag entering a cavity are reduced, thereby benefiting guarantee of the quality of molten iron; and the product quality of the castings is improved. 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 pot, in particular to an anti-siphon sprue pot and a method for making and using it. Background technique [0002] The sprue basin is connected to the top of the sprue, and is used to receive and introduce molten metal into the container, so that the molten metal reaches a suitable pouring speed before flowing into the sprue. 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 cause slag inclusion pores in castings. Contents of the invention [0003] The invention overcomes the quality defects of castings such as slag inclusions and air holes caused by the Yihong suction of the sprue pot, and provides an anti-siphon sprue pot and its production and use method, which ...
