Abstract
The utility model relates to a multiple row mould for casting steel balls, which comprises a sand separating mould, a metal mould and an aluminum soil mould. A plurality of ball bodies are arranged by a vertical form in arrangement methods of a single row or a plurality of rows. The balls are communicated by a casting channel. A direct pouring opening is injected with molten steel once, and thus the ball bodies are shaped. After the ball bodies are shaped to 900 DEG C, the moulds are unloaded, and the ball bodies are taken out and are tempered after quenched. The utility model has the advantages of high utilization rate of the molten steel and high finished product rate.
Description
The utility model relates to a kind of pattern of sand mold vertical steel ball casting, is used for the casting mould that solidification of molten steel becomes steel ball.Metal pattern, aluminium Fan clay model.
Existing steel ball casting mould all is flat pattern cast, and the molten steel of running channel consume about 25% of the gross weight that accounts for have only 3/4ths utilization rate, and percent defective is higher, has caused very big waste.
A kind of steel ball casting metal pattern has been invented by Hebei Polytechnical College the year before, and pattern is single cast steel ball, also can save a part of molten steel, but production efficiency is low also undesirable, does not also have to excavate the potentiality of saving molten steel to the greatest extent and enhancing productivity.
The purpose of this utility model is exactly in order to overcome the deficiency of above-mentioned prior art, and a kind of utilization rate that makes steel ball casting improve molten steel is provided, and easy and simple to handle, and cost is low, the pattern that production efficiency is high.
The purpose of this utility model can realize that whole enforcement branch two procedures is carried out by following scheme: first procedure is according to two HT20-40 cast iron type templates with 20 holes of figure casting, 20 half knob stubs.Tolerance by drawing carries out machined then, is assembled into the patterns of arranging more.Second operation work prepares the pattern sandbox, blending type sand, surface layer sand are coal dust sand, coke powder sand, high alumina flour sand, and the many arrange types template that assembles is placed on the level ground, the pattern sandbox is placed on many arrange types template, real toward molding sand, Chinese toon that the interior assembling of sandbox makes.Overturn then sandbox, pattern template.Take off many arranged models from sandbox, also can spill model in the bottom, again by above-mentioned technology, arrange that half steel ball tip of a twig type of system, two fan sand molds have all made on the patterns more, lumping together for half two is exactly a complete sand casting pattern.This arrangement is used for metal pattern equally.To not be after iron and steel is dissolved, be cast as the mould of producing abrasion-proof steel ball, its architectural feature is that the outline of pattern is rectangular three-dimensional shape, pattern is divided into opposite opened two fans, the die joint of every fan all is half a garden ball-shape of arranged vertical, between the steel ball die cavity of die cavity (4) and running channel (2) arranged vertical, be communicated with by running channel (2) entirely, two fan patterns are located by Xiao hole, behind the fastening, become a complete spheroid die cavity, be divided into a plurality of arrangements of vertical single file, duplicate rows is to a plurality of arrangements of multirow, when injecting molten steel at the pattern top, by cast gate (1) through cast gate (2), rising head (3) falls into steel ball die cavity (4), is communicated with through running channel (2) and waters full each steel ball die cavity.Running channel (2), it is that cast gate also is a rising head.Be cooled to 900 ℃ when steel ball solidifies, i.e. quench cooled is carried out in die sinking.
The utility model can make the steel ball casting yield rate reach more than 98%, and molten steel Utilization rate reaches more than 95%, obviously enhances productivity, and has reduced cost, and steel ball quality is good.
The explanation of Figure of description drawing: Figure of description 1 is the full structural front view of pattern, splits the fan in two fans, (identical mid section figure).
1, down gate; 2, running channel; 3, rising head; 4, steel ball; 5, pattern plate.
Claims (2)
1, a kind of steel ball casting is arranged pattern more, to not be after iron and steel is dissolved, be cast as the mould of producing abrasion-proof steel ball, its architectural feature is that the outline of pattern is rectangular three-dimensional shape, pattern is divided into opposite opened two fans, every fan somatotype face all is half a garden shape spheroid of arranged vertical, between the steel ball die cavity of die cavity (4) and running channel (2) arranged vertical, be communicated with by running channel (2) entirely, after two fan patterns are fastened by location, Xiao hole, become a complete spheroid die cavity, be divided into a plurality of arrangements of vertical single file or duplicate rows to a plurality of arrangements of multirow, when injecting molten steel at the pattern top, by cast gate (1) through cast gate (2), rising head (3) falls into steel ball die cavity (4), is communicated with through running channel (2) and waters full each steel ball die cavity.
2, steel ball casting according to claim 1 is arranged pattern more, it is characterized in that running channel (2), and it is that cast gate also is a rising head.
